global energy use decoupling or convergence we examine the key factors driving change in energy use globally over the past four decades we test for both strong decoupling where economic growth has less effect on energy use as income increases and weak decoupling where energy use declines overtime in richer countries ceteris paribus our econometric approach is robust to the presence of unit roots unobserved time effects and spatial effects our key findings are that the growth of per capita energy use has been primarily driven by economic growth convergence in energy intensity and weak decoupling there is no sign of strong decoupling

does economic recession reduce material use empirical evidence based on 157 economies worldwide abstract the research on economic recession has been more focused on the interactions between macroeconomic and financial variables however whether material use has been affected during the recession period has remained under explored in order to fill up this gap this study investigates the relationship between material use and economic recession as well as other socio economic drivers by using the material flow analysis and the system generalized method of moments for 157 economies worldwide during 1980 2011 results show that economic recession poses significant and negative impact on domestic material consumption at 1 level illustrating its role as a determinant factor on material mitigation by dividing the research sample into extractive and non extractive economies as well as high mid and low income groups we again confirmed the significant negative correlations as expected no significant sign is found between recession and physical trade balance besides other drivers such as population gross domestic production gdp per capita and technological variables also exert marked effects at different situations this research work provides an empirical study on how recession and other factors affect material use at various scenarios which have essential implications for understanding material flow dynamics in different economic cycles

new venture survival ignorance external shocks and risk reduction strategies abstract although scholars have long recognized the increased mortality risk that new ventures face in terms of a liability of newness most of the discussion around this risk has been in terms of the contextual constraints that new ventures face and the difficulties that managers have in overcoming them this emphasis is in part a reflection of the perils of newness but also stems from the retrospective and aggregate perspective taken by researchers although the macro level perspective of new venture mortality has made a significant contribution to our knowledge of mortality risk patterns there has been little interest in identifying how venture managers can address the risks that all new organizations face we argue that in order to make progress in explaining new venture survival a theoretical model is required that uses a more micro level perspective to explain new venture failure and the flip side new venture survival in this paper we develop such a model we establish a definition of mortality risk and argue that the liability of newness is largely dependent on the degree of novelty ignorance associated with a new venture novelty is viewed in three different dimensions viz to the market to the technology of production and to management novelty to the market concerns the degree to which the customers are uncertain about the new venture novelty in production concerns the extent to which the production technology used by the new venture is similar to the technologies in which the production team has experience and knowledge novelty to management concerns the entrepreneurial team s lack of business skills industry specific information and start up experience we argue that mortality risk increases with the degree of novelty in each dimension and with the number of dimensions in which the new venture is novel we propose that the decline in mortality risk occurs as the venture s novelty in each of the three dimensions is eroded by information search and dissemination processes this allows the new firm to become an established business and explains what we term the evolutionary path of mortality novelty and risk decline monotonically after a period of adolescence as ignorance decays over time due to passive learning we also propose that there is a strategic mortality risk path that reflects the impact of positive and negative shocks shocks are exogenous events that alter the overall degree of novelty at a point in time positive shocks decrease overall novelty while negative shocks increase overall novelty and reversals endogenous actions that increase the overall novelty of the new venture at a point in time on the mortality risk of a new venture if the incidence and effects of these disruptions can be managed then venture managers may be able to mitigate the mortality risk for their venture we argue that risk reduction strategies can be employed most of which impact on one or more of the dimensions of mortality risk in order to increase the firm s chances of survival a series of risk reduction strategies are proposed and their impact on the determinants of mortality risk is considered

income resources and electricity mix this paper presents evidence on a national level electricity ladder which sees countries transition toward coal and natural gas and finally nuclear power and modern renewables such as wind power for their electricity needs as they develop the extent to which countries climb the electricity ladder is dependent on energy endowments the results imply that the environmental implications of economic development differ in countries with different energy resource endowments an effective global carbon mitigation strategy will require developing countries to leapfrog the middle rungs of the electricity ladder

the physical dimension of international trade part 1 direct global flows between 1962 and 2005 abstract the physical dimension of international trade is attaining increased importance this article describes a method to calculate complete physical trade flows for all countries which report their trade to the un the method is based on the un comtrade database and it was used to calculate world wide physical trade flows for all reporting countries in nine selected years between 1962 and 2005 the results show increasing global trade with global direct material trade flows reaching about 10 billion tonnes in 2005 corresponding to a physical trade volume of about 20 billion tonnes adding both total imports and total exports the share from european countries is declining mainly in favour of asian countries the dominant traded commodity in physical units was fossil fuels mainly oil physical trade balances were used to identify the dominant resource suppliers and demanders australia was the principal resource supplier over the period with a diverse material export structure it was followed by mainly oil exporting countries with varying volumes as regards to regions latin america south east asian islands and central asia were big resource exporters mostly with increasing absolute amounts of net exports the largest net importers were japan the united states and single european countries emerging countries like the asian tigers with major industrial productive sectors are growing net importers some of them to an even higher degree than european countries altogether with the major exception of australia and canada industrialized countries are net importers and developing countries and transition countries are net exporters but there are important differences within these groups

sustainable de growth mapping the context criticisms and future prospects of an emergent paradigm article i nfo sustainable de growth is both a concept and a social grassroots northern movement with its origins in the fieldsofecologicaleconomics socialecology economicanthropologyand environmentalandsocialactivistgroups this paper introduces the concept of sustainable de growth by mapping some of the main intellectual influences fromthese fields with special focus on the francophone and anglophone thinking about this emergent notion we propose hypotheses pertaining to the appeal of sustainable de growth and compare it to the messages enclosed within the dominant sustainable development idea we scrutinize the theses contradictions and consequences of sustainable de growth thinking as it is currently being shaped by a heterogeneous body of literature and as it interacts with an ample and growing corpus of social movements we also discuss possible future paths for the de growth movement compared to the apparent weakening of the sustainable development paradigm

decoupling of emissions and gdp evidence from aggregate and provincial chinese data abstract we provide a comprehensive analysis of the relationship between greenhouse gas ghg emissions and gdp in china using both aggregate and provincial data the trend or kuznets elasticity is about 0 6 for china higher than that in advanced countries but below that of major emerging markets the elasticity is somewhat lower for consumption based emissions than for production based emissions providing mild evidence consistent with the pollution haven hypothesis the kuznets elasticity is much lower for the last three decades than for the three previous decades suggesting a longer term trend toward decoupling as china has become richer further evidence of this comes from provincial data richer provinces tend to have smaller kuznets elasticities than poorer ones in addition to the trend relationship we find that there is a cyclical relation also holding in china

stochastic convergence in per capita fossil fuel consumption in u s states abstract this study examines the stochastic convergence of per capita fossil fuel consumption across u s states including the district of columbia utilizing lm and rals lm unit root tests with allowance for endogenously determined structural breaks our results indicate that with the exception of nevada the evidence from two break and one break lm and rals lm unit root tests rejects the null hypothesis of a unit root in the relative per capita fossil fuel consumption in the u s this finding indicates the presence of stochastic convergence in relative per capita fossil fuel consumption in the u s states

the effects of stock market growth and renewable energy use on co2 emissions evidence from g20 countries the primary objective of this study is to empirically examine the effect of stock market growth and foreign direct investment fdi inflows on co2 emissions further this study investigates the impact of renewable energy consumption on co2 emissions and economic output in a panel of the g20 countries the empirical analysis was carried out on the full sample as well as on sub samples of developed and developing economies of the g20 member countries the results confirm a significant long run equilibrium relationship among the variables across the panels further the long run elasticities suggest that fdi significantly reduces co2 emissions in the full sample and developing economies while stock market growth reduces in developed economies similarly the renewable energy consumption substantially reduces co2 emissions and increases economic output across the panels our findings have important policy implications for instance the policy makers have to initiate effective policies to promote the renewable energy sources to meet the increasing demand for energy by replacing the use of conventional energy such as coal gas and oil this will therefore help to reduce the co2 emissions and also ensure sustainable economic development in the g20 nations

industrialization electricity consumption and co2 emissions in bangladesh this paper investigates the relationship between industrialization electricity consumption and co2 emissions in case of bangladesh using quarter frequency data over the period of 1975 2010 the ar

energy consumption carbon emissions and economic growth in saudi arabia an aggregate and disaggregate analysis the objective of this study is to examine the relationship among economic growth carbon emissions and energy consumption at the aggregate and disaggregate levels for the aggregate energy consumption model we use total energy consumption per capita and co2 emissions per capita based on the total energy consumption for the disaggregate analysis we used oil gas and electricity consumption models along with their respective co2 emissions the long term income elasticities of carbon emissions in three of the four models are positive and higher than their estimated short term income elasticities these results suggest that carbon emissions increase with the increase in per capita income which supports the belief that there is a monotonically increasing relationship between per capita carbon emissions and per capita income for the aggregate model and for the oil and electricity consumption models the long and short term income elasticities of carbon emissions are negative for the gas consumption model this result indicates that if the saudi arabian economy switched from oil to gas consumption then an increase in per capita income would reduce carbon emissions the results also suggest that electricity is less polluting than other sources of energy

between estimates of the emissions income elasticity abstract recent papers by wagner and vollebergh et al point out some fundamental econometric problems with traditional methods of estimating the environmental kuznets curve ekc and propose alternative approaches that avoid these issues wagner notes that traditional methods do not take into account the presence of powers of unit root variables and cross sectional dependence in the data while vollebergh et al point out that the time effects are not uniquely identified in the ekc model the between estimator is a simple estimator that also addresses the concerns of these authors it makes no a priori assumption about the nature of the time effects and is likely to provide consistent estimates of long run relationships in real world data situations i apply several common panel data estimators including the between estimator to oecd and global carbon and sulfur emissions datasets the between estimates of the sulfur income elasticity are 0 732 in the oecd and 1 067 in the global data set and the estimated carbon income elasticity is 1 612 in the oecd and 1 509 globally

co2 emissions renewable energy and the environmental kuznets curve a panel cointegration approach abstract this study combines a panel cointegration analysis with a set of robustness tests to assess the short and long run impacts of renewable energy on co2 emissions as well as the kuznets environmental curve hypothesis for 25 selected african countries over the period 1980 2012 the results provide no evidence of a total validation of ekc predictions however co2 emissions are found to increase with income per capita the overall estimations strongly reveal that renewable energy with a negative effect on co2 emissions coupled with an increasing long run effect remains an efficient substitute for the conventional fossil fuelled energy nonetheless the impact of renewable energy is outweighed by primary energy consumption in both the short and long run entailing more global synergy for outpacing the environmental challenges

assessing the energy saving effect of urbanization in china based on stochastic impacts by regression on population affluence and technology stirpat model abstract the rapid urbanization process has posed great challenges to china s energy system this paper uses the stochastic impacts by regression on population affluence and technology stirpat model to evaluate the energy saving effect of china s urbanization based on provincial panel data the results suggest that 1 the urbanization induces the energy consumption with a notable negative energy saving effect 2 the heterogeneity of urbanization impact on energy consumption is analyzed in different stages of urbanization showing that the energy saving effect of urbanization follows a u shaped path 3 considering the heterogeneity of the energy saving effect of urbanization at different income levels the energy saving effect increases with income level the outcome may draw a causation picture on the relationship between energy consumption and urbanization in addition an in depth causation analysis on energy inefficiency of china s urbanization is carried out and policy recommendations are put forward accordingly

the effects of energy prices urbanization and economic growth on energy consumption per capita in 186 countries abstract energy is the material basis for the development of national economy however energy shortages become increasingly serious as a result of the growing population and the modernization of the global economy therefore investigating drivers of energy consumption is crucial to coordinate the relationship between energy and national economic growth this study aimed to uncover the effects of energy prices ep urbanization urn and gdp on per capita energy consumption ec with considering the income gaps between countries the paper adopted the granger causality test approach and the impulse response function analysis by using long term time series data on ec ep urn and gdp during 1980 2015 in 186 countries divided into three groups high income upper and lower middle income groups the results indicated a long term co integration relationship among these variables granger causality test showed a bidirectional causality between urn and ec in high and lower middle income countries but no causality in the upper middle income group in all groups there is a bidirectional causal link between gdp and ec the results of irf showed that as urbanization level improves its role in promoting ec become less significant moreover ep affected ec negatively both in high and lower middle income countries but it has a positive impact on ec in upper middle income countries the study supports the finding that urbanization is an important factor affecting energy consumption per capita although its contributions vary across income groups which offers a new pathway to control the excessive growth of energy consumption

energy and resource allocation a dynamic model of the dutch disease it is well known that a domestic resource discovery gives rise to wealth effects that cause a squeeze of the tradeable good sector of an open economy the decline of the manufacturing sector following an energy discovery has been termed the dutch disease and has been investigated in many recent studies our model extends the principally static analyses to date by allowing for 1 short run capital specificity and long run capital mobility 2 international capital flows and 3 far sighted intertemporal optimizing behaviour by households and firms the model is solved by numerical simulation

carbon pricing efficacy cross country evidence to date there has been an absence of cross country empirical studies on the efficacy of carbon pricing in this paper we present estimates of the contribution of carbon pricing to reducing national carbon dioxide co2 emissions from fuel combustion using several econometric modelling approaches that control for other key policies and for structural factors that are relevant for emissions we use data for 142 countries over a period of two decades 43 of which had a carbon price in place at the national level or below by the end of the study period we find evidence that the average annual growth rate of co2 emissions from fuel combustion has been around 2 percentage points lower in countries that have had a carbon price compared to countries without an additional euro per tonne of co2 in carbon price is associated with a reduction in the subsequent annual emissions growth rate of approximately 0 3 percentage points all else equal while it is impossible to fully control for all relevant influences on emissions growth our estimates suggest that the emissions trajectories of countries with and without carbon prices tend to diverge over time

is china s economic growth decoupled from carbon emissions abstract a comprehensive understanding of the interdependence between china s economy and carbon emissions can better serve china s transition towards a low carbon economy and can also provide reference for other developing countries the purpose of this paper was to investigate the dependence of china s economy on co2 emissions i the tapio decoupling model was applied to quantify the decoupling elasticity between china s economy and co2 emissions ii the structure decomposition technique was utilized to quantity the contribution of china s economic structure to the decoupling elasticity iii the combined decomposition model which combined cobb douglas c d production function with logarithmic mean divisia index lmdi technique and was solved the residual problem was employed to identify more driving factors labor input investment carbon coefficient energy structure energy intensity economic structure and technology state affecting the decoupling elasticity the main results were as follows i the decoupling elasticity showed a downward trend during the whole period and the decoupling state was characterized by two types expansive negative decoupling 2002 2005 and weak decoupling 2000 2002 and 2005 2014 ii the industry sector played the most negative effect on the decoupling process expect 2013 2014 from the cumulative effect the contribution of six sectors to promote decoupling effect was ranked as follows construction agriculture trade other transport industry iii the most critical factor driving the increased co2 emissions was the investment effect accounting for 145 34 of the cumulative total co2 emissions while the energy intensity effect contributed to a cumulative reduction in co2 emissions of 1443 72 mt finally some policy recommendations were offered to achieve the decoupling of china s economic growth and carbon emissions

voter information and power dilution evidence from sicilian provincial elections it is generally accepted that an increase in the amount of voter information is desirable as reisman 1990 points out a well informed and committed electorate is better able to exercise rational choice and consequently is less likely to have its wishes being thwarted by elected representatives in this connection a crucial question relates to the effect of increased voter information on power of elected representatives in other words does increased voter information dilute or increase the power of political parties from the answer to this question flow numerous conclusions about the size of rents enjoyed by political parties under differing electoral systems

environmental degradation economic growth and energy consumption evidence of the environmental kuznets curve in malaysia this paper tests for the short and long run relationship between economic growth carbon dioxide co2 emissions and energy consumption using the environmental kuznets curve ekc by employing both the aggregated and disaggregated energy consumption data in malaysia for the period 1980 2009 the autoregressive distributed lag ardl methodology and johansen juselius maximum likelihood approach were used to test the cointegration relationship and the granger causality test based on the vector error correction model vecm to test for causality the study does not support an inverted u shaped relationship ekc when aggregated energy consumption data was used when data was disaggregated based on different energy sources such as oil coal gas and electricity the study does show evidences of the ekc hypothesis the long run granger causality test shows that there is bi directional causality between economic growth and co2 emissions with coal gas electricity and oil consumption this suggests that decreasing energy consumption such as coal gas electricity and oil appears to be an effective way to control co2 emissions but simultaneously will hinder economic growth thus suitable policies related to the efficient consumption of energy resources and consumption of renewable sources are required

is decoupling economic growth from fuel consumption possible in developing countries a comparison of china and india abstract a better understanding the coupling decoupling of economic growth from energy demand in china and india can serve both countries and other developing countries to achieve the goal of gaining higher economic growth with less energy demand to demonstrate the relationship between coupling decoupling economy and energy in china and india better this work has made following contributions i analyzes the decoupling elasticity between economic growth and energy consumption by using the tapio model ii explores the five key effects labor input investment energy structure energy intensity technology level of decoupling elasticity by combining the cobb douglas c d function and log mean divisia index lmdi method and iii evaluates the decoupling efforts by applying decoupling efforts model in china and india between 1990 and 2015 the decoupling elasticity results show china s decoupling elasticity curve is in an inverted u shaped trend and the decoupling elastic value is concentrated between 0 and 0 8 in most years showing a weak decoupling state furthermore the decoupling state is strong decoupling during 2014 2015 indicating china has initially achieved the decoupling of economy and energy consumption while india s decoupling elasticity presents irregular fluctuations indicating that india s decoupling status is not very satisfactory the decomposition results uncover that major effects of decoupling in china and india are similar i e the investment effect is the biggest driver which contributed to a cumulative increasing impact in energy consumption in china and india by 3017 10 million tonnes oil equivalent and 675 18 million tonnes oil equivalent respectively whereas the energy intensity effect is the greatest inhibiting factor which contributed to a cumulative reduction in energy consumption in china and india by 1437 81 million tonnes oil equivalent and 139 21 million tonnes oil equivalent the decoupling efforts results show decoupling effort in china is better than that in india improving energy efficiency is the leading contributor to china s decoupling efforts while advancing technology is the major contributor to india s decoupling effort

identifying reduced form relations with panel data the case of pollution and income abstract in this paper we propose a solution to the non robustness that plagues the estimation of inverted u shaped relationships using panel data such as the relation between pollution and income when dependent and independent variable like pollution and income are both time related separating the effect of the independent variable from time effects brings about a fundamental identification dilemma the imposition of restrictions on the controls might drive the shape of the relationship between the dependent pollution and independent income variables our solution consists of imposing the very weak constraint that arbitrary cross sectional units have the same relationship we apply our methodology to two widely studied cases namely so 2 and co 2 emissions interestingly our estimates are insensitive to the required subjective choices but also strongly differ from the literature so far we find consistent positive income effects for both cases and time effect estimates with a clear u shaped trend for so 2 emissions but only slightly so for co 2 emissions

agency in action entrepreneurs networking style and initiation of economic exchange this multimethod study investigates the effects of entrepreneurs interpersonal networking style on the initiation of interorganizational exchange ties i use inductive theorizing to make a distinction between interpersonal networking actions aimed at adding new contacts network broadening actions versus managing existing contacts network deepening actions i reason that because networking actions alter the cost benefit calculus of using referrals the extent to which entrepreneurs rely on referrals when searching for new exchange partners should vary with their networking actions i then propose that entrepreneurs are likely to add fewer new exchange partners when they rely more on referrals to search the empirical analysis employs a longitudinal design using data coded from the business cards of new contacts formed over a two month period by a panel of indian entrepreneurs operating business to business ventures this study makes a theoretical contribution by identifying decision makers networking style as a distinct mechanism shaping partner selection for their organization specifically the study shows entrepreneurs using more network deepening actions initiate fewer new economic exchanges due in part to their increased reliance on referral based search whereas entrepreneurs using more network broadening actions initiate more new economic exchanges due in part to their decreased reliance on referral based search

closeness expenditures and turnout in the 1982 u s house elections students of elections have repeatedly found that the closeness of an election is modestly correlated with turnout this may be due to a direct response of instrumentally motivated voters but recent theoretical work casts doubt on the adequacy of this explanation another possibility is that elite actors respond to closeness with greater effort at mobilization we explore the latter possibility by using fec and state data on campaign expenditures in house senate and gubernatorial races our results indicate that closeness has an effect at both the mass and elite levels we also provide quantitative estimates of the effect of senate and gubernatorial expenditure on house turnout

getting out the vote participation in gubernatorial elections scholarship on electoral turnout has long emphasized two main themes explanations of nonvoting in terms of individual characteristics and in terms of contextual variables these investigations have deeply enriched our understanding of electoral participation but their limitations have also sensitized us to the remaining problems of explanation perusal of the work on american politics exposes a rather striking tendency in studies of participation to ignore or soft pedal the effects of active political mobilization in this article we formulate two models of electoral turnout socioeconomic and political mobilization and apply them to aggregate data on voting in gubernatorial elections of 1978 and 1980 the socioeconomic model of turnout includes such influences as income age and educational attainment to assess the effects of political mobilization we have considered campaign spending partisan competition electoral margin and the presence or absence of a simultaneous race for the united states senate both of the models perform quite well individually producing significant and meaningful coefficients and adequate fits yet in the final analysis we demonstrate that quite apart from major sources of variation in gubernatorial turnout such as region and presidential versus nonpresidential years the mobilizing influences of campaign activism and competitiveness have a strong impact on electoral participation electoral law i e closing date of registration retains a small but significant effect on voting for governor and socioeconomic characteristics included in a fully specified model have little to contribute independently to an explanation of electoral turnout these findings are very much in the same vein as related cross national investigations which emphasize the crucial role of electoral law and political parties and downplay individual characteristics as determinants of electoral participation on the basis of the research reported here we argue that scholars need to pay more attention to political mobilization as an explanation of electoral turnout in the presidential election between cox and harding in 1920 only half of the eligible voters participated this relatively low turnout together with the historically minimal rates of participation in state and local elections created deep concern among those who believed that reasonably high levels of political involvement are crucial in maintaining a healthy democratic politics it was in this atmosphere of worry about low electoral turnout that charles e merriam and harold f gosnell 1924 conducted in the city of chicago the first systematic study of nonvoting subsequently gosnell 1927 went even further and executed the first experimental study in modern political science demonstrating conditions that could stimulate electoral turnout we too worry about low participation in elections today at every level of government and we believe these classic studies

china s changing energy intensity trend a decomposition analysis china experienced a dramatic decline in energy intensity from the onset of economic reform in the late 1970s until 2000 but since then the rate of decline slowed and energy intensity actually increased in 2003 most previous studies found that most of the decline was due to technological change but disagreed on the role of structural change to the best of our knowledge no decomposition study has investigated the role of inter fuel substitution in the decline in energy intensity or the causes of the rise in energy intensity since 2000 in this paper we use logarithmic mean divisia index lmdi techniques to decompose changes in energy intensity in the period 1980 2003 we find that 1 technological change is confirmed as the dominant contributor to the decline in energy intensity 2 structural change at the industry and sector sub industry level actually increased energy intensity over the period of 1980 2003 although the structural change at the industry level was very different in the 1980s and in the post 1990 period 3 structural change involving shifts of production between sub sectors however decreased overall energy intensity 4 the increase in energy intensity since 2000 is explained by negative technological progress 5 inter fuel substitution is found to contribute little to the changes in energy intensity

toward to economic growth without emission growth the role of urbanization and industrialization in china and india abstract the contradiction between economic growth and carbon emissions in china and india is the most prominent in the world both countries have faced tremendous pressures to curb carbon emissions because they are major source of new added emission sources meanwhile both countries have faced greater pressures to achieve industrialization and urbanization in order to eradicate poverty better understanding the decoupling status and its drivers can serve to develop effective policy to achieve economic growth without an increase in emission this paper comparatively analyses the decoupling effect of the economic growth from the carbon emissions as well as its drivers during the period 1980 2014 in china and india the tapio decoupling model was used to analyze the decoupling status and the co integration theory and the impulse response functions were applied to investigate the effects of urbanization industrialization per capita gdp and carbon emission intensity to decoupling the results show that china mainly performed a weak decoupling of economic growth from carbon emissions in 1980 2014 while the decoupling status of india was no regular in china carbon emission intensity is the biggest contributor of decoupling followed by urbanization per capita gdp and industrialization in india the biggest driver of decoupling is also the carbon emission intensity followed by urbanization industrialization and per capita gdp therefore improving energy efficiency is the best policy to toward economic growth without emission growth in china and india

an ecological macroeconomics model the energy transition in the eu abstract the energy roadmap 2050 er2050 is committed to achieve the european union s emissions mitigation goals by reducing energy use and a transition to renewables the macroeconomic impacts of the ref16 and euco scenarios of this strategy have been reported to entail an absolute decoupling between gdp growth and energy use the aim of this paper is assessing the er2050 targets with a novel modelling methodology based on post keynesian economics i e demand led economic growth and ecological economics i e taking into account absolute biophysical energy availability constrains to economic growth thus this article presents the economy module of the integrated assessment model medeas europe combining system dynamics and input output analysis and evaluates the er2050 targets under different scenarios regarding primary income distribution foreign trade labour productivity industrial policy and working time reduction our results show that gdp growth and employment creation may be halted due to energy scarcity if the er2050 targets are met even considering great energy efficiency gains in addition the renewables share would increase enough to reduce the energy imports dependency but not sufficiently to meet the emissions targets only a post growth scenario would be able to meet the climate goals and maintain the level of employment

energy paths in the european union a model based clustering approach this paper examines typical energy paths i e the intertemporal development of the energy mixes of the member states of the european union over 1971 2010 we apply model based clustering to detect major energy profiles and their compositional dynamics the seven identified clusters show typical combinations of energy carriers dominating the primary energy consumption of a country we find that countries tend to take a path towards higher quality energy mixes over time however path inertia and dependencies arise from both infrastructure and resource endowments higher energy quality profiles are usually associated with higher national income and energy use per capita providing some evidence of the existence of a national level energy ladder we also find convergence in energy intensity over time and a relationship between a country s own resources and import dependency

price and income elasticities of residential and industrial electricity demand in the european union this study examines the short and long run price and income elasticities of residential and industrial electricity demand in the european union between 1996 and 2016 instrumental variable models using the between estimator as well as dynamic panel models are employed to present robust estimates and to assess the impact of different methodologies on the reported elasticities the long run price elasticity of residential electricity consumption is estimated between 0 53 and 0 56 these elasticities are more inelastic than that of industrial electricity use which is reported between 0 75 and 1 01 the choice of different econometric methodologies has only moderate impact on the estimates while long run residential income elasticity estimates are moderately inelastic and estimated around 0 61 industrial electricity use tends to be closely tied to income with elasticities between 0 76 and 1 08 electricity demand in all sectors is highly price and income inelastic in the short run additionally population density temperatures and policy measures also influence sectoral electricity use the above estimates can aid the design of european energy and environmental policy

convergence analysis of city level energy intensity in china abstract understanding the convergence patterns of energy intensity and the drivers leading to the club convergence are of great significance for local governments to implement targeted policies to improve energy efficiency with this in mind we begin with the collection of energy consumption data of 193 chinese cities at prefecture level or above then we adopt the log t test and clustering algorithm to investigate convergence characteristics of energy intensity besides the ordered probit model is adopted to investigate the drivers that affect the formulation of convergent club we identify four convergent clubs among total 193 cities and these clubs show great differences in energy intensity marketization degree population density foreign direct investment resource endowment and industrial structure are recognized as the drivers of the formation of convergence clubs this paper adds more evidence to understand the energy intensity gap we propose that upgrading the industrial structure exerting economic assemble advantage enhancing the level of opening up and improving the marketization level are favorable measures to reduce energy intensity

is there convergence in per capita renewable energy consumption across u s states evidence from lm and rals lm unit root tests with breaks abstract given the federal and state policy initiatives to curb fossil fuel consumption and expand the use of renewable energy sources in the u s this study investigates the convergence properties of per capita renewable energy consumption across u s states including the district of columbia in addition to cross sectional tests of and convergence our study employs lm and rals lm unit root tests with endogenously determined structural breaks to test for stochastic convergence traditional cross sectional tests indicate that both and convergence of per capita renewable energy consumption exists across u s states moreover our results also provides clear support for stochastic convergence of per capita renewable energy consumption for a majority of u s states including the district of columbia once allowance is made for structural breaks

decoupling analysis and environmental kuznets curve modelling of provincial level co2 emissions and economic growth in china a case study abstract guangdong is one of the most representative provinces of china in terms of reflecting how the provincial level co2 emissions dynamically evolve with economic development during the process of industrialisation and urbanisation the present study combines decoupling analysis with environmental kuznets curve ekc modelling to systematically explore the interactions between co2 emissions and economic growth in guangdong from the short to long terms aiming to provide the referential significance of low carbon development to other chinese provinces empirical results indicate that co2 economy interactions in guangdong dynamically changed with time performing an effect of expansive weak decoupling during 1995 2014 and having a potential to achieve a strong decoupling in the long run the decoupling states of various sectors and their contributions to the provincial overall decoupling differed greatly and varied by time and household and service sectors played increasingly important roles overall the decoupling effect of provincial co2 emissions is distinctly affected by the stage of industrialisation and urbanisation renewable energy utilisation as well as low carbon technical progress therefore promoting co2 economy decoupling at the provincial level should be specific to the feature and development reality of various provinces

modeling energy and development an evaluation of models and concepts most global energy models are developed by institutes from developed countries focusing primarily on issues that are important in industrialized countries evaluation of the results for asia of the ipcc sres models shows that broad concepts of energy and development the energy ladder and the environmental kuznets curve can be observed in the results of the models however improvements can be made in modeling the issues that underlie these concepts like traditional fuels electrification economic structural change income distribution and informal economies given the rapidly growing importance of energy trajectories of developing countries for global sustainability the challenge for the future is to develop energy models that include all these aspects of energy and development

renewable energy output co2 emissions and fossil fuel prices in central america evidence from a nonlinear panel smooth transition vector error correction model abstract this study examines the determinants of renewable energy consumption per capita for a panel of seven central american countries over the period 1980 to 2010 specifically we find that a long run cointegrated relationship exists between renewable energy consumption per capita real gdp per capita carbon emissions per capita real coal prices and real oil prices with the respective coefficients positive and statistically significant a structural break in the cointegrating relationship appears in 2002 which coincides with the establishment of the energy and environment partnership with central america initiative to expand the use of renewable energy sources recognizing the regime shift in 2002 we estimate a nonlinear panel smooth transition vector error correction model to show that for the post 2002 period the influence of renewable energy consumption per capita upon real coal and oil prices strengthened relative to the pre 2002 period as well as a greater sensitivity of real gdp per capita to carbon emissions per capita

will history repeat itself economic convergence and convergence in energy use patterns in this paper a difference in differences estimator on panel data for 30 developing and 21 industrialized countries is employed over the period 1971 2005 to examine how patterns of energy use characterized by the consumption of primary energy carriers sectoral energy use and carbon emissions are changing in the process of economic development for the average developing country in our sample the results indicate that economic catch up has been accompanied by above average growth of the use of most primary energy carriers the consumption of final energy in most sectors and total co2 emissions for industrialized countries we find that economic growth is partially decoupled from energy consumption and that above average rates of economic growth were accompanied by larger improvements in energy efficiency these results emphasize the need to identify the relevant engines of economic growth their implications for energy use and possibilities to achieve low carbon growth centered on productivity and efficiency improvements rather than on capital accumulation

rule of law and the resource curse abundance versus intensity we examine the resource curse using new data on historic resource stocks and an improved econometric methodology the paper distinguishes between resource abundance stocks and extractive intensity flows focusing on relationships between resources and rule of law previously unavailable information on past resource stocks is estimated we find that economically large initial natural resource stocks are associated with subsequent lower levels of rule of law and do not directly affect growth while raw resource exports do not have a significant effect on rule of law when stocks are included in the analysis but do affect average growth rates sample size is maximized through the use of an emis expectation maximization with importance sampling algorithm to replace missing data minimizing the bias and inefficiency associated with listwise deletion which commonly eliminates half or more of the available data in this setting

the physical dimension of international trade part 2 indirect global resource flows between 1962 and 2005 global trade is increasingly being challenged by observations of growing burden shifting in particular of environmental problems this paper presents the first worldwide calculations of shifted burden based on material flow indicators in particular direct and indirect physical trade balances this study covers the period between 1962 and 2005 and includes between 82 and 173 countries per year the results show that indirect trade flow volumes have increased to around 41 billion tonnes in 2005 the traded resources with the highest share of associated indirect flows are iron hard coal copper tin and increasingly palm oil regarding the burden balance between regions europe is the biggest shifter whereas australia and latin america are the largest takers of environmental burden due to resource extraction to evaluate the findings from a global perspective the results are analysed in terms of resource flow induced environmental pressure related to a country s land area in terms of total and per capita area resource endowment and population density seem to be more relevant in determining the physical trade balance including indirect flows than income level

inside the black box of outcome additionality effects of early stage government subsidies on resource accumulation and new venture performance this paper examines the outcome additionality of prestigious early stage government subsidies drawing on arguments from liabilities of newness and certification literatures we develop a mediated model that unpacks the outcome additionality of the subsidy we hypothesize that subsidized new ventures attract more human and financial capital than their non subsidized counterparts because the association with a prestigious government organization signals legitimacy of the new venture such legitimacy is crucial for attracting qualified employees and financiers the effect of the access to human and financial capital in turn has long term and substantial influence on performance whereas the effect of the subsidy itself is marginal and short lived applying a novel matching approach we compare 130 approved applicants of a prestigious government subsidy with a control group of 154 applications rejected at the very last stage thereby overcoming some of the selection and endogeneity biases associated with similar studies the hypothesized model receives strong support by the data these findings have several implications for government support of new ventures as well as scholars in the field

does ecologically unequal exchange occur the hypothesis of ecologically unequal exchange posits that low and middle income developing nations maintain an ecological deficit with wealthy developed nations exporting natural resources and high impact commodities thereby allowing wealthy economies to avoid operating ecologically impactful industries at home in this survey we assess the footprint of consumption of 187 countries using eight indicators of environmental pressure in order to determine whether or not this phenomenon occurs we use input output analysis with a new high resolution global multi region input output table to calculate each trading pair s balance of trade in biophysical terms of ghg emissions embodied water and scarcity weighted water content air pollution threatened species human appropriated net primary productivity total material flow and ecological footprint we test three hypotheses that should be true if ecologically unequal exchange occurs one the inter regional balance of trade in biophysical terms is disproportional to the balance of trade in financial terms we find this is true though not strongly so two exports from developing nations are more ecologically intensive than those from developed nations we find this is true three high income nations disproportionately exert ecological impacts in lower income nations we find this is false high income nations are mostly exporters not importers of biophysical resources

macroeconomic modelling under energy constraints global low carbon transition scenarios abstract integrated assessment models provide a framework to study sustainability transitions and their economic impacts models seldom consider energy constraints taking supply availability for granted and thus suggesting a mere change in the energy mix from non renewables to renewables in order to address these limitations a macro economic module within a broader system dynamics model medeas has been developed the model has been run for the whole world from 1995 to 2050 under three different scenarios business as usual bau considering no further transition policies and keeping current trends green growth gg undertaking the low carbon transition according to the paris agreement set of policies and with high gdp growth standards and post growth pg testing the sustainability transition under a gdp non growth degrowth approach the results reveal the conflict between economic growth climate policy and the sustainability of resources whereas a bau approach would not even be an option to achieve climate goals a gg view would not only face the downsizing of economic output but neither would it be able to achieve the 2 c objective the success of the pg approach in meeting emissions objectives suggests a redirection from economic growth policies to an industrial policy that incorporates efficiency and redistribution

embracing digital networks entrepreneurs social capital online abstract this paper presents a research agenda for understanding how entrepreneurs accrue social capital in the digital age we develop a conceptual framework with 12 research propositions that specify how the unique technical capabilities of social network sites impact entrepreneurs bridging and bonding social capital online these propositions are informed by anecdotal evidence from founders that finds entrepreneurs social capital accrual differs online we include theoretical and methodological insights for overcoming research challenges concerning context dynamism intertwined networks and unclear behavioral norms this agenda addresses a growing gap between contemporary entrepreneurial practices and existing social capital theory and research in entrepreneurship

a multivariate cointegration analysis of the role of energy in the us macroeconomy abstract this paper extends my previous analysis of the causal relationship of gdp and energy use in the usa in the post war period a majority of the relevant variables are integrated justifying a cointegration analysis the results show that cointegration does occur and that energy input cannot be excluded from the cointegration space the results are plausible in terms of macroeconomic dynamics the results are similar to my previous granger causality results and contradict claims in the literature based on bivariate models that there is no cointegration between energy and output

decomposing the decoupling of co2 emissions and economic growth in brazil abstract this paper examines the occurrence of a decoupling between the growth rates in economic activity and co 2 emissions from energy consumption in brazil from 2004 to 2009 this decoupling was highlighted when economic activity and co 2 emissions moved in opposite directions in 2009 more generally we observe several periods of relative decoupling in brazil but not to the extent witnessed in 2009 to identify the determinants of emissions change we develop a decomposition model based on a log mean divisia index lmdi framework the results indicate that the carbon intensity and energy mix are the main determinant of emissions reduction in brazil between 2004 and 2009 modifications in the economy structure are also associated to emission mitigation in the period such evidence demonstrates similarities with events of decoupling registered for the interval 1980 1994 in brazil finds from brazil differ from observations in other countries in which improvement in energy intensity has been the most common determinant of emissions reduction

technological progress and sustainable development what about the rebound effect abstract sustainability concepts that rest on the idea of resource or energy efficiency improvements due to technological progress tend to overestimate the potential saving effects because they frequently ignore the behavioral responses evoked by technological improvements efficiency improvements also affect the demand for resources and energy and often an increase in efficiency by 1 will cause a reduction in resource use that is far below 1 or sometimes it can even cause an increase in resource use this phenomenon is commonly labeled the rebound effect which is well known among energy economists but never attracted much attention in ecological economics the paper starts with the traditional neoclassical analysis of the rebound effect in a partial equilibrium framework that concentrates on the demand of one particular energy service such as mobility or room temperature it also provides an overview of some of the main empirical studies based on this model that mostly confirm the existence of the rebound effect but are controversial about its actual importance however we have to go beyond the neoclassical single service model in order to take care of the variety of possible feedback affecting energy use the paper presents two important expansions of the single service model in order to show the potential relevance of the rebound effect to ecological economics first it is shown that in a multi services model it proves to be difficult to make general statements about the relevance of the rebound effect in this case the overall effect of an increase in energy efficiency on total energy use depends on the on the assumptions about the substitutability between the services considered and the direction of the income effect second the paper also tries to take care of the fact that changes in resource use or energy use are frequently just side effects of other forms of technological progress especially technological change of a time saving nature can have a large influence on energy use as many time saving devices for example faster modes of transport require an increase in energy consumption that is frequently reinforced by a rebound effect with respect to time this effect will be especially strong when wages are high and at the same time energy prices are low as is currently the case in most industrialized countries consequently the paper also provides a strong argument for the introduction of energy taxes

does urbanization lead to less energy use and lower co2 emissions a cross country analysis despite the relationship between urbanization energy use and co2 emissions has been extensively studied in recent years little attention has been paid to differences in development stages or income levels most previous studies have implicitly assumed that the impact of urbanization is homogenous for all countries this assumption can be questionable as there are many characteristic differences among countries of different levels of affluence this paper investigates empirically the effects of urbanization on energy use and co2 emissions with consideration of the different development stages using the stochastic impacts by regression on population affluence and technology stirpat model and a balanced panel dataset of 99 countries over the period 1975 2005 the findings suggest that the impact of urbanization on energy use and emissions varies across the stages of development surprisingly urbanization decreases energy use in the low income group while it increases energy use in the middle and high income groups the impact of urbanization on emissions is positive for all the income groups but it is more pronounced in the middle income group than in the other income groups these novel findings not only help advance the existing literature but also can be of special interest to policy makers and urban planners

panel estimation for co2 emissions energy consumption economic growth trade openness and urbanization of newly industrialized countries abstract this paper empirically examines the dynamic causal relationships between carbon dioxide emissions energy consumption economic growth trade openness and urbanization for the panel of newly industrialized countries nic using the time series data for the period 1971 2007 using four different panel unit root tests it is found that all panel variables are integrated of order 1 from the johansen fisher panel cointegration test it is found that there is a cointegration vector among the variables the granger causality test results support that there is no evidence of long run causal relationship but there is unidirectional short run causal relationship from economic growth and trade openness to carbon dioxide emissions from economic growth to energy consumption from trade openness to economic growth from urbanization to economic growth and from trade openness to urbanization it is found that the long run elasticity of carbon dioxide emissions with respect to energy consumption 1 2189 is higher than short run elasticity of 0 5984 this indicates that over time higher energy consumption in the newly industrialized countries gives rise to more carbon dioxide emissions as a result our environment will be polluted more but in respect of economic growth trade openness and urbanization the environmental quality is found to be normal good in the long run

decoupling economic growth from carbon emissions growth in the united states the role of research and development abstract the united states has achieved economic growth compatible with carbon reduction since 2007 this work is addressed to understand the eight effects especially effects related to research development rd whereas economic scale was the primary inhibitor to the drop of carbon emission followed by investment intensity population size and sectoral energy structure the results of decoupling efforts analysis uncover that energy intensity r d intensity r d efficiency and sectoral carbon intensity contributed to decoupling economic growth from carbon emission whereas investment intensity population size and sectoral energy structure did not contribute to the decoupling finally some policy implications are proposed

does increasing investment in research and development promote economic growth decoupling from carbon emission growth an empirical analysis of brics countries abstract it is generally recognized that increasing research and development investment is an effective measure to promote economic and social progress an open question is if increasing research and development investment help economic growth decoupling from carbon emission this study investigates research and development investment and carbon emission in brics countries by using the fully modified ordinary least squares for empirical estimation from 1996 to 2014 the results show that every 1 increase in research and development investment carbon emissions will be decreased by 0 8122 for the brics as a whole which indicates increasing research and development investment has a positive impact on decoupling economic growth from environmental pressure for individual this impact is most significant in china weak in russia and india however it also should be noted that only increasing research and development investment cannot achieve the decoupling between economic growth and carbon emission because other factors such as economic activity industrialization and urbanization renewable energy also influences the decoupling economic growth from carbon emission the results also show that economic activity industrialization and urbanization pose negative impact on the decoupling whereas renewable energy consumption promote the decoupling

does the use of renewable energy sources mitigate co2 emissions a reassessment of the us evidence abstract previous research on the determinants of co 2 emissions has concluded that although increasing nuclear energy consumption can help to mitigate emissions increasing use of renewable energy sources is not effective in this regard these studies however do not consider energy prices as a possible driver of energy demand and hence of emissions and we find that this omission and the choice of functional form materially alters the outcome in the us case specifically our cointegration and granger causality test results indicate that co 2 emission levels are negatively related to the use of renewable energy but are unrelated to nuclear energy consumption

global patterns of materials use a socioeconomic and geophysical analysis abstract human use of materials is a major driver of global environmental change the links between materials use and economic development are central to the challenge of decoupling of materials use and economic growth dematerialization this article presents a new global material flow dataset compiled for the year 2000 covering 175 countries including both extraction and trade flows and comprising four major material categories biomass construction minerals fossil energy carriers and ores industrial minerals first we quantify the variability and distributional inequality gini coefficients in international material consumption we then measure the influence of the drivers population gdp land area and climate this analysis yields international income elasticities of material use finally we examine the coupling between material flows and between income and material productivity measured in economic production per tonne material consumed material productivity is strongly coupled to income and may thus not be suitable as an international indicator of environmental progress a finding which we relate to the economic inelasticity of material consumption the results demonstrate striking differences between the material groups biomass is the most equitably distributed resource economically the most inelastic and is not correlated to any of the mineral materials the three mineral material groups are closely coupled to each other and economic activity indicating that the challenge of dematerializing industrial economies may require fundamental structural transformation our analysis provides a first systematic investigation of international differences in material use and their drivers and thus serves as the basis for more detailed future work

the convergence of u s state level energy intensity abstract this study extends a neoclassical growth model to include the accumulation of physical capital and energy consumption within a panel of fifty states plus the district of columbia in the u s the theoretical model allows us to examine the implications for convergence in economic growth and energy intensity from the theoretical model we formulate an empirical approach using a dynamic panel model that is estimated using a general method of moments framework to test the conditional rates of convergence the empirical results indicate convergence in energy intensity and our estimates accurately predict both the growth in and convergence of energy intensity across our entire sample consistent with other findings in the literature our results imply that energy use over the past four decades plays a small and positive role in state level per capita economic growth and convergence based on these results we discuss policy implications for state level income growth and energy consumption

impact of natural gas consumption on co 2 emissions panel data evidence from china s provinces abstract this study utilizes 1995 2014 panel data of the 30 provinces in china to investigate the existence of the environmental kuznets curve ekc for carbon dioxide co 2 emissions in china the potential impact of natural gas consumption on co 2 emissions is also analyzed according to the panel fully modified ordinary least squares fmols and panel dynamic ols dols estimation results in the long run an inverted u shaped ekc link exists between per capita co 2 emissions and per capita gross domestic product gdp in the panel fmols model and panel dols model with 99 261 yuan and 59 159 yuan for per capita gdp the ekc of china will reach its peak by around 2029 or 2019 respectively furthermore natural gas consumption has a significant negative impact on co 2 emissions which indicates that 1 increase in natural gas consumption for the panel fmols model and panel dols model will decrease co 2 emissions by 0 033627 or 0 054914 respectively at the provincial level provinces in which the ekc hypothesis holds are predominantly concentrated in central and eastern china and the energy consumption structure share of natural gas in total energy consumption may affect the occurrence of a significant negative impact of natural gas consumption on co 2 emissions another finding of this study is that both the existence of ekc and the occurrence of a positive negative impact of natural gas consumption on co 2 emissions are independent of the individual provincial per capita gdp

understanding the energy gdp elasticity a sectoral approach abstract this paper uses per capita data for 132 countries over 1960 2010 to estimate elasticities of sectoral energy use with respect to national gross domestic product gdp we estimate models in both levels and growth rates and use our estimates to sectorally decompose the aggregate energy gdp elasticity our estimates show that residential energy use is very inelastic to gdp if primary solid biofuels are counted in energy use tallies especially at low income levels residential use of electricity is more tightly linked to gdp as is energy use by the transportation industrial and services sectors agriculture typically accounts for a small share of energy use and has a modest energy gdp elasticity the aggregate energy gdp elasticity tends to be higher for countries at higher income levels in large part because traditional use of primary solid biofuels is less important gasoline prices winter temperature population and land area are among other factors influencing sectoral energy use

firm networks and firm development the role of the relational mix abstract this study examines the role of different networks called the relational mix on the development of the entrepreneurial firm our regression analysis of survey data from 60 venture capital financed firms questions the importance of network size on firm development rather our results suggest that different types of networks are more important for firm development in particular we found a significant positive relationship for reputational networks and a weak significant negative relationship for cooperative technology networks at founding with time to break even social networks at founding have no direct effect on time to break even and a significant negative relationship with sales in the years after foundation furthermore our findings show the important role of marketing information and co opetition networks relationships with direct competitors on firm development in the years after foundation these results suggest that the relational mix is a more appropriate construct for explaining network development than network size alone

towards a common renewable future the system gmm approach to assess the convergence in renewable energy consumption of eu countries abstract this paper investigates whether the contribution of renewable energy sources to primary energy consumption is characterized by a convergence process across core european union eu countries over the period from 1990 to 2014 the system generalized method of moments gmm methodology is employed for 5 year span panel data of 14 eu members the findings indicate strong evidence for both the absolute unconditional and conditional convergence of renewables share in primary energy consumption across eu 14 countries moreover the control variables namely co2 emissions per gdp fdi inward stock and electricity prices contribute to the speed of convergence hence the implicit rate of conditional convergence is higher than that of absolute convergence the empirical evidence suggests that the energy mixes of core eu members have a tendency to become similar in the long run as the shares of res in primary energy consumption converge to the average level nonetheless it does not necessarily imply that this average would be 20 target which is to be achieved by 2020 according to eu directive 2009 28 ec

why do governments subsidize gasoline consumption an empirical analysis of global gasoline prices 2002 2009 abstract governments spend hundreds of billions of dollars annually to subsidize the consumption of fossil fuels without understanding the environmental and economic problems this practice creates to shed light on these problems we examine the case of gasoline subsidies using data on gasoline prices in 137 countries for the years 2002 2009 it is useful to study gasoline pricing because gasoline is the most important transportation fuel and there are data for many countries for the time period of investigation we find that major oil producers subsidize gasoline consumption by artificially reducing prices countries with weak institutional capacity also seem to subsidize gasoline but the effects are weaker these results suggest that policy interventions to improve institutional capacity could help developing countries in particular reduce their fossil fuel subsidies

modelling socio economic and energy data to generate business as usual scenarios for carbon emissions abstract the uk government is legally committed to achieving an 80 reduction in carbon dioxide emissions compared with 1990 by 2050 the use of scenarios is wide ranging to inform policy development and forming a business as usual scenario helps to understand possible effects of different policy interventions however the term business as usual is frequently misused we show how econo physical business as usual scenarios can be developed by examining the historical behaviour of coefficients which manifest the relationship between components of an economy we endogenise economic growth by mimicking national level policies that focus on a target level of unemployment our case study demonstrates the trendability of coefficients which for one example coefficient is replicated for australia colombia taiwan and the usa we manifest a gross domestic product growth of 2 falling to 1 which contrasts with an exogenous growth of 2 3 of a comparator business as usual scenario we suggest that it may be possible to achieve a greater reduction in the business as usual carbon dioxide emissions in the uk fifth carbon budget than currently projected

structural change and convergence of energy intensity across oecd countries 1970 2005 abstract this paper uses new and unique data derived from a consistent framework of national accounts to compute and evaluate energy intensity developments across 18 oecd countries and 50 sectors over the period 1970 2005 we find that across countries energy intensity levels tend to decrease in most manufacturing sectors in the service sector energy intensity decreases at a relatively slow rate with diverse trends across sub sectors a decomposition analysis reveals that changes in the sectoral composition of the economy explain a considerable and increasing part of aggregate energy intensity dynamics a convergence analysis reveals that only after 1995 cross country variation in aggregate energy intensity levels clearly tends to decrease driven by a strong and robust trend break in manufacturing and enhanced convergence in services moreover we find evidence for the hypothesis that across sectors lagging countries are catching up with leading countries with rates of convergence that are on average higher in services than in manufacturing aggregate convergence patterns are almost exclusively caused by convergence of within sector energy intensity levels and not by convergence of the sectoral composition of economies

renewable energy consumption economic growth nexus for china abstract the aim of this paper is to investigate the relationship between renewable energy consumption and economic growth in china for the period 1977 2011 autoregressive distributed lag approach ardl to cointegration and johansen cointegration techniques are employed by including intermittent variables namely carbon dioxide emissions and labor we also employed granger causality test in order to determine the direction of the causality among the variables the results show that there is a bi directional long term causality between renewable energy consumption and economic growth this finding implies that growing economy in china is propitious for the development of renewable energy sector which in turn helps to boost economic growth we also find that labor influences renewable energy consumption in the short term however there is no evidence of long or short run causality between carbon emissions and renewable energy consumption this implies that actual level of renewable energy in china is still insignificant and not considerably exploited in order to contribute to the mitigation of carbon dioxide emissions

starting up in a turbulent environment a process model of failure among firms with high customer dependence abstract this paper proposes a process model on how new and small organizations may fail based on prior research the paper builds a foundation for a process model and then elaborates it inductively by explaining how and why significant reversals and shifts occurred between 1983 and 1985 in the entrepreneurial organizational and ecological conditions of ten new educational software companies the process model states that all organizations engage in transactions with others in the normal conduct of business and it is inevitable that a certain proportion of these transactions fail the probability of transaction failures is a product of the failure rate at the level of the organizational population as well as the kinds of transactions in which individual firms engage new and small firms in a turbulent environment represent a subset of the organizational population particularly vulnerable to the chance occurrence of a failed transaction because of liabilities of newness and small size these firms lack legitimacy furthermore in many industries there is an absence of tangible physical assets that entrepreneurs can use as collateral to attract valuable resources and customers in such situations entrepreneurs often use transactions with key external constituencies as a surrogate to attract other resource constituents thus giving rise to a leveraged set of transactions this leveraging strategy however makes the set of transactions of the firm tightly coupled and when any one transaction in a tightly coupled set fails the set often collapses hence a small business firm in this situation fails when a transaction in which it is highly dependent or leveraged happens to fail the very strategies that contributed to overcoming the problems of liabilities of newness and small size turn out to be the root causes of failure the experiences of the courseware companies are generalized to a process model of failure of new small businesses in turbulent environments

when should entrepreneurs expedite or delay opportunity exploitation abstract we theorize on the performance implications of the timing at which entrepreneurs stop exploring their business opportunities and start exploiting them using an optimal stopping approach we characterize the time when exploitation should begin based primarily on when an entrepreneur s ignorance has been sufficiently reduced through knowledge accumulation this ignorance threshold captures a tradeoff between the time needed to increase legitimacy and the necessity to act now to minimize competition changes in legitimacy and competition are based on how entrepreneurs manage their knowledge tacit versus explicit under differing degrees of novelty for the business opportunity these changes in turn impact the performance and timing of opportunity exploitation

the impact of competitors firm power divergence on chinese smes environmental and financial performance competitor pressure is one of the major reasons that a sme engages in environmentally friendly or damaging activities extant research has argued that environmental strengths and concerns have mirror opposite relationships with stakeholder antecedents as well as with performance outcomes we suggest this argument does not reflect the reality building on stakeholder management and red queen theories we hypothesize that environmental strengths and concerns have differential relationships with competitors firm power exchange and financial performance for chinese smes results of ten interviews a pretest and a large scale field study indicate that competitors firm power divergence has a positive relationship with environmental strengths yet the link between this divergence and environmental concerns does not exist further environmental strengths mediate the relationship between competitors firm power divergence and financial performance of chinese smes

hostile environmental jolts transaction set and new business abstract in this exploratory study we examine empirically the effects of environmental jolts on the evolution of the set of relationships that entrepreneurs have with their customers and suppliers which we call the transaction set we believe that understanding how turbulence in the environment affects the ability of entrepreneurs to hold on to their existing relationships or to add new relationships is fundamental to understanding the evolution and growth of an organization from a start up to a stable wealth creating enterprise in the long run using longitudinal data spanning 7 to 10 years from five start up firms we investigate three questions on the connection between environmental jolts and changes in the transaction set of the firm first do environmental jolts during the early life of the firm induce significant reductions in the set of relationships of a new small firm second are entrepreneurs able to add new relationships in greater numbers than the exit of old relationships following a jolt and third do start ups enjoy a honeymoon period when environmental jolts do not induce significant reductions in the set of relationships after a jolt our study yielded several findings that may be of interest to entrepreneurs academics and incubator managers first environmental jolts have a significant impact on the exits of relationships from the transaction set of a new small firm but not necessarily on the entry of new relationships into the set thus although liabilities of newness and small size seem to affect the ability of entrepreneurs to hold on to their existing relationships during environmental jolts these jolts do not seem to affect the entrepreneur s ability to add ties at least in the very early life of the firm second the level of reduction after environmental jolts seems to be less severe during the early life and greatest during the adolescent period further entries of new relationships decrease with each succeeding jolt one implication of our findings is that environmental selection pressures are more severe after an incubation period called the honeymoon period a second implication of our findings is the way in which liability of adolescence manifests itself the honeymoon does not provide incubation against exits of relationships rather the incubation manifests itself in the form of the willingness of new customers and suppliers to join the entrepreneur s transaction set even during a jolt however this goodwill shown by new customers and suppliers decreases with each succeeding jolt thus making the firm very vulnerable to failure during its adolescent phase of life we believe our study emphasizes the role that chance plays in the early survival and growth of firms firms lucky to avoid hostile jolts after their honeymoon period will be in a better position to grow rapidly other things being equal despite sound management and superior exercise of enterprise jolts appear in the life of firms in a stochastic often unpredictable fashion although it is not clear that firms who have superior enterprise ability or slack are more likely to succeed than those who don t what is clear is that the ability to survive and grow is seriously affected with each succeeding jolt whatever the ability if our findings and our inference from the findings are general they have an important public policy implication for new small companies conventional wisdom holds that given liabilities of newness and small size incubator environments are best provided to start up firms we would recommend a different strategy incubator environments are best provided not at the start up stage to new business but at the adolescent stage incubators should be provided to companies that show during the honeymoon phase that their ideas and products have merit and that they can attract customers and investors to their venture it is during the adolescent stage that firms are most vulnerable to environmental disturbances and where ability may not be a sufficiently good discriminator between survival and failure

is political rivalry an incentive to vote according to the theory of the rational voter s behavior riker and ordeshook 1968 the decision to vote depends among other things on the expected effectiveness of his vote to bring to power his preferred candidate or party though this hypothesis is valid in the case of a two party political system in the case of a multi party system one has to take into consideration the influence of the competition2 between parties upon the vote s efficiency and on the distribution of the votes among parties3 in a multi party system quite often no one party is in a position to win an overal majority and the result is a governmental coalition therefore the voter is in more doubt about the effectiveness of his vote for a given number of parties the closer the outcome of the election the more likely people would be to vote see tullock 1972 110 an increase in the number of parties might be considered as contributing to a better representation of the electorate s preferences and therefore as an incentive to vote on the other hand when parties become too numerous there could be a weakening of power among them and that in turn would cancel out the incentive to vote therefore an optimal degree of competition encouraging electoral participation as shown in figure 1 must exist4 this paper will concentrate on the assessment of the explanatory power of the competition among parties upon the rate of electoral participation it should however not be overlooked that in practice there are many factors of an institutional as well as of a psychological nature which prevent such an ideal balance being attained factors affecting the voter s behavior such as compulsory participation tend to reduce considerably the margin between the expected benefit from voting and the costs the development of efficient lobbies considered by the voter to be more likely to support his preferences in parliament tend to reduce the

plurality versus proportional representation an analysis of sicilian elections the competing merits of plurality and proportional representation have intrigued political economists and political scientists for quite some time of primary interest is whether one or the other system is better in serving the interests of the electorate since theoreticians are unable to unambiguously determine the answer to this question the issue must ultimately be decided empirically

drivers of industrial and non industrial greenhouse gas emissions abstract though there has been extensive analysis of the drivers of aggregate carbon dioxide emissions from fossil fuel combustion and cement production there has been much less analysis of the drivers of greenhouse gases in general and especially of aggregate emissions of greenhouse gases from agriculture forestry and other land uses which we call non industrial emissions in this paper we statistically analyze the relationship between both industrial and non industrial greenhouse gas emissions and economic growth and other potential drivers for 129 countries over the period from 1971 to 2010 our analysis combines the three main approaches in the literature into a single framework for investigating the evolution of emissions and income we find that economic growth is a driver of both industrial and non industrial emissions though economic growth has twice the effect on industrial emissions the time effect is negative for both sources of emissions though this effect is larger for non industrial emissions there is also convergence in emissions intensity for both types of emissions but given these other effects there is no evidence for an environmental kuznets curve

dynamics of final sectoral energy demand and aggregate energy intensity this paper proposes a regional and sectoral model of global final energy demand for the main end use sectors of consumption industrial commercial and public services residential and road transportation per capita demand is expressed as an s shaped function of per capita income other variables intervene as well like energy prices temperatures and technological trends this model is applied on a panel of 101 countries and 3 aggregates covering the whole world and it explains fairly well past variations in sectoral final consumption since the beginning of the 2000s further the model is used to analyze the dynamics of final energy demand by sector and in total the main conclusion concerns the pattern of change for aggregate energy intensity the simulations performed show that there is no a priori reason for it to exhibit a bell shape as reported in the literature depending on initial conditions the weight of basic needs in total consumption and the availability of modern commercial energy resources various forms might emerge

decoupling analysis of world economic growth and co2 emissions a study comparing developed and developing countries abstract this study discusses decoupling trends in world economic growth and co2 emissions based on decoupling theories the decoupling trends of economic growth and co2 emissions in typical developed and developing countries in 1965 2015 are compared by using an oecd decoupling factor model and tapio elastic analysis tea method and the igtx decoupling model on this basis this study evaluates correlations of these three decoupling models by employing the spearman s rank correlation coefficient the research indicates that owing to the igtx decoupling model being easily affected by other non environmental factors the shorter the research period of interest the more easily the decoupling indices distort while the accuracy of the tea method is not limited by the length of the research period of interest with respect to the overall decoupling trend the research shows that 1 strong decoupling is found in developed countries and slightly increases in the stabilisation thereof the decoupling state in the united kingdom and germany is more stable than that of the united states and france 2 developing countries demonstrate weak decoupling that fluctuates significantly and lacks regularity the stabilisation and optimisation of china in decoupling process are better than those of brazil and india finally according to research conclusions relevant policies and suggestions are proposed in view of energy savings and emissions reduction in developing countries

income and democracy existing studies establish a strong cross country correlation between income and democracy but do not control for factors that simultaneously affect both variables we show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and vari ous measures of democracy we present instrumental variables estimates that also show no causal effect of income on democracy the cross country corre lation between income and democracy reflects a positive correlation between changes in income and democracy over the past 500 years this pattern is con sistent with the idea that societies embarked on divergent political economic development paths at certain critical junctures jel d7 e 1

decoupling global environmental pressure and economic growth scenarios for energy use materials use and carbon emissions in recent decades economic growth and increased human wellbeing around the globe have come at the cost of fast growing natural resource use including materials and energy and carbon emissions leading to converging pressures of declining resource security rising and increasingly volatile natural resource prices and climate change we ask whether well designed policies can reduce global material and energy use and carbon emissions with only minimal impacts on improvements in living standards we use a novel approach of combined economic and environmental modelling to assess the potential for decoupling for 13 world regions and globally we apply a production territorial and consumption approach to discuss regional differences in natural resource use and carbon emissions across three stylized policy outlooks a reference case with no significant changes to environment and climate policies a high efficiency outlook involving a global carbon price rising from 50 to 236 constant price per tonne of co2 between 2010 and 2050 and improvements in resource efficiency rising from 1 5 historically to between 3 5 and 4 5 in the scenarios and a medium efficiency outlook midway between the no change and high outlooks we find that global energy use will continue to grow rapidly under all three scenarios from 17 billion tonnes of oil equivalent toe in 2010 to between 30 and 36 billion toe carbon emissions would be considerably lower with a global carbon price less than half the level of the reference case 29 37 billion tonnes of co2 instead of 74 billion tonnes and also material use would grow much more slowly under a carbon price and significant investment to increase resource efficiency 95 instead of 180 billion tonnes of materials we find that oecd economies have significant potential to reduce their material throughput and carbon emissions with little impact on economic growth and that developing economies such as china could expand their economies at much lower environmental cost globally the effects of very strong abatement and resource efficiency policies on economic growth and employment until 2050 are negligible our study suggests that decarbonization and dematerialization are possible with well designed policy settings and would not contradict efforts to raise human wellbeing and standards of living the research demonstrates the usefulness of scenarios for unpacking environmental and economic outcomes of policy alternatives the findings have important implications for future economic opportunities in a highly resource efficient and low carbon global economy to set human development and achieving the sustainable development goals on a more resilient path

the causal relationship between renewable electricity generation and gdp growth a study of energy sources abstract this paper examines the causal relationship between economic growth and electricity generation from renewable sources biomass geothermal hydroelectric solar waste and wind across 20 oecd countries over 1990 to 2008 the results from a commonly used panel error correction model find a a bidirectional relationship between aggregate renewable generation and real gdp b biomass hydroelectricity waste and wind energy exhibit a positive long run relationship with gdp c hydroelectricity and waste generation exhibit a short run positive bidirectional relationship with gdp growth and d biomass hydroelectric and waste electricity generation have the largest impact on real gdp in the long run we extend the analysis to consider the possibility of structural breaks and cross sectional dependence accounting for cross sectional dependence we find that in the short run increases in biomass and waste generation negatively affect gdp while aggregate renewable and hydroelectricity increase gdp energy conservation policies will positively impact gdp if the policies cause decreases in biomass or waste energy but increase hydroelectricity and wind energy

energy consumption and economic growth in central america evidence from a panel cointegration and error correction model abstract this study examines the relationship between energy consumption and economic growth for six central american countries over the period 1980 2004 within a multivariate framework given the relatively short span of the time series data a panel cointegration and error correction model is employed to infer the causal relationship based on the heterogeneous panel cointegration test by pedroni pedroni p 1999 critical values for cointegration tests in heterogeneous panels with multiple regressors oxford bulletin of economics and statistics 61 653 670 pedroni p 2004 panel cointegration asymptotic and finite sample properties of pooled time series tests with an application to the ppp hypothesis new results econometric theory 20 597 627 cointegration is present between real gdp energy consumption the labor force and real gross fixed capital formation with the respective coefficients positive and statistically significant the granger causality results indicate the presence of both short run and long run causality from energy consumption to economic growth which supports the growth hypothesis
