an analysis of the driving forces of energy related carbon dioxide emissions in china s industrial sector abstract both energy consumption and the growth of carbon dioxide co2 emissions in china are attributed to the industrial sector energy conservation and co2 emissions reduction in china s industrial sector is decisive for achieving a low carbon transition we analyze the change of energy related co2 emissions in china s industrial sector from 1991 to 2010 based on the logarithmic mean divisia index lmdi method results indicate that industrial activity is the major factor that contributes to the increase of industrial co2 emissions while energy intensity is the major contributor to the decrease of co2 emissions industry size shows a varying trend interchanging intervals of growth along the study period moreover both energy mix and carbon intensity of energy use have negative effects on the increase of co2 emissions the cointegration method is adopted to further explore determinants of co2 emissions in china s industrial sector results show that there exists a long run relationship between industrial co2 emissions and affecting factors such as co2 emissions per unit of energy consumption industrial value added labor productivity and fossil fuel consumption china s industrial co2 emissions are mainly attributed to the coal dominated energy structure policy suggestions are thus provided to reduce industrial co2 emissions in china

reduction potentials of energy demand and ghg emissions in china s road transport sector abstract rapid growth of road vehicles private vehicles in particular has resulted in continuing growth in china s oil demand and imports which has been widely accepted as a major factor effecting future oil availability and prices and a major contributor to china s ghg emission increase this paper is intended to analyze the future trends of energy demand and ghg emissions in china s road transport sector and to assess the effectiveness of possible reduction measures a detailed model has been developed to derive a reliable historical trend of energy demand and ghg emissions in china s road transport sector between 2000 and 2005 and to project future trends two scenarios have been designed to describe the future strategies relating to the development of china s road transport sector the business as usual scenario is used as a baseline reference scenario in which the government is assumed to do nothing to influence the long term trends of road transport energy demand the best case scenario is considered to be the most optimized case where a series of available reduction measures such as private vehicle control fuel economy regulation promoting diesel and gas vehicles fuel tax and biofuel promotion are assumed to be implemented energy demand and ghg emissions in china s road transport sector up to 2030 are estimated in these two scenarios the total reduction potentials in the best case scenario and the relative reduction potentials of each measure have been estimated

a dynamic approach to the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis states that pollution levels increase as a country develops but begin to decrease as rising incomes pass beyond a turning point in ekc analyses the relationship between environmental degradation and income is usually expressed as a quadratic function with the turning point occurring at a maximum pollution level other explanatory variables have been included in these models but income regularly has had the most significant effect on indicators of environmental quality one variable consistently omitted in these relationships is the price of energy this paper analyzes previous models to illustrate the importance of prices in these models and then includes prices in an econometric ekc framework testing energy income and co2 income relationships these long run price income models find that income is no longer the most relevant indicator of environmental quality or energy demand indeed we find no significant evidence for the existence of an ekc within the range of current incomes for energy in the presence of price and trade variables

tourism as a long run economic growth factor the spanish case this paper examines the role of tourism in the spanish long run economic development the tourism led growth hypothesis is confirmed through cointegration and causality testing the results indicate that at least during the last three decades economic growth in spain has been sensible to persistent expansion of international tourism the increase of this activity has produced multiplier effects over time external competitivity has also been proved in the model to be a fundamental variable for spanish economic growth from the empirical analysis it can be inferred the positive effects on income that government policy in the adequacy of supply as well as in the promotion of tourist activity may bring about

the long run causal relationship between transport energy consumption and gdp evidence from heterogeneous panel methods robust to cross sectional dependence abstract this paper employs panel methods that address mitigate heterogeneity and cross sectional dependence to determine the direction and sign of long run causality between transport energy consumption per capita and real gdp per capita granger causality was determined to run from gdp to energy

economic growth and pollutant emissions in tunisia an empirical analysis of the environmental kuznets curve abstract this paper investigates the relationship between economic growth and pollutant emissions for a small and open developing country tunisia during the period 1961 2004 the investigation is made on the basis of the environmental kuznets curve hypothesis using time series data and cointegration analysis carbon dioxide co 2 and sulfur dioxide so 2 are used as the environmental indicators and gdp as the economic indicator our results show that there is a long run cointegrating relationship between the per capita emissions of two pollutants and the per capita gdp an inverted u relationship between so 2 emissions and gdp has been found with income turning point approximately equals to 1200 constant 2000 prices or to 3700 in ppp constant 2000 prices however a monotonically increasing relationship with gdp is found more appropriate for co 2 emissions furthermore the causality results show that the relationship between income and pollution in tunisia is one of unidirectional causality with income causing environmental changes and not vice versa both in the short run and long run this implies that an emission reduction policies and more investment in pollution abatement expense will not hurt economic growth it could be a feasible policy tool for tunisia to achieve its sustainable growth in the long run

are there multiple bubbles in the ethanol gasoline price ratio of brazil this paper tests for the existence of bubbles in the ethanol gasoline price ratio in brazil from 2000 to 2012 using right tailed adf tests results suggest the existence of two bubbles one which has already burst during the re election of president lula and one which has been ongoing since 2010 thus corroborating empirical and anecdotal evidence in the brazilian sugarcane industry freezing gasoline prices not only depressed ethanol prices but also depressed investments in new sugarcane crops and distillation plants

environmental kuznets curve hypothesis in pakistan cointegration and granger causality abstract the paper is an effort to fill the gap in the energy literature with a comprehensive country study of pakistan we investigate the relationship between co2 emissions energy consumption economic growth and trade openness in pakistan over the period of 1971 2009 bounds test for cointegration and granger causality approach are employed for the empirical analysis the result suggests that there exists a long run relationship among the variables and the environmental kuznets curve ekc hypothesis is supported the significant existence of ekc shows the country s effort to condense co2 emissions and indicates certain achievement of controlling environmental degradation in pakistan furthermore we find a one way causal relationship running from economic growth to co2 emissions energy consumption increases co2 emissions both in the short and long runs trade openness reduces co2 emissions in the long run but it is insignificant in the short run in addition the change of co2 emissions from short run to the long span of time is corrected by about 10 yearly

environmental kuznets curve in romania and the role of energy consumption abstract the aim of present study is to probe the dynamic relationship between economic growth energy consumption and co 2 emissions for period of 1980 2010 in case of romania in doing so ardl bounds testing approach is applied to investigate the long run cointegration between these variables our results confirm long run relationship between economic growth energy consumption and energy pollutants the empirical evidence reveals that environmental kuznets curve ekc is found both in long and short runs in romania further energy consumption is major contributor to energy pollutants democratic regime shows her significant contribution to decline co 2 emissions through effective implementation of economic policies and financial development improves environment i e reduces co 2 emissions by redirecting the resources to environment friendly projects

discrete equilibrium price dispersion an explicit solution of an equilibrium model with price setting firms and searching customers makes possible a number of comparativestatics predictions about how cost differences among firms search costs of customers and taxes will affect the mean and variance of the distribution of market prices another implication of the model is that a firm s demand depends on the difference between its price and the average price in the market

china s energy consumption and sustainable development comparative evidence from gdp and genuine savings this paper employs the structural vector autoregressions framework and the generalized impulse response function to study the long term dynamic relation between china s energy consumption and sustainable economic growth in addition to the conventional economic indicators gdp growth rates genuine savings rates are particularly examined to indicate sustainable economic development results show that the high elasticity of energy consumption dramatically undermines the capacity of china s sustainability in terms of reducing genuine savings rates we also use variance decomposition to calculate relative variance contribution rates in order to identify the most important factor affecting gdp growth as well as genuine savings rates the analysis finds that clean and renewable energy increase the country s genuine savings significantly that is renewable energy consumption promotes sustainable development for both natural and economic societies however increase in traditional solid energy consumption is more likely to benefit only the growth of gdp

the aim end use model and its application to forecast japanese carbon dioxide emissions abstract the asian pacific integrated model aim has been developed for predicting greenhouse gas emissions and evaluating policy measures to reduce them two socioeconomic scenarios were assumed and co 2 emissions were predicted based on these scenarios and policy intervention assumptions it is found that mitigating co 2 emissions by 6 to the 1990 level is possible without scaling back productive activities or living standards in japan however this cannot be achieved by relying on the market mechanism alone our analysis shows that it is indispensable to introduce new policies and measures such as a carbon tax and subsidies

indicators for sustainable energy development a multivariate cointegration and causality analysis from tunisian road transport sector this paper studies causal mechanism between indicators for sustainable energy development related to energy consumption from tunisian road transport sector the investigation is made using the johansen cointegration technique and the environmental kuznets curve ekc approach it examines the nexus between transport value added road transport related energy consumption road infrastructure fuel price and co2 emissions from tunisian transport sector during the period of 1980 2010 empirical results show that road transport related energy consumption transport value added transport co2 emissions and road infrastructure are mutually causal in the long run these results do not support the hypothesis of neutrality between energy and income for the tunisian road transport sector also there is a unidirectional causality running from fuel price to road transport related energy consumption with no feedback in both the short and long runs the fuel price and the road infrastructure are significant in the causal chain though the estimated long run cointegrated equation we conclude that there is an inverse n shaped relation between transport value added and transport co2 emissions with income turning point respectively equal to 75 and 579 constant 2000 tnd prices therefore our empirical findings refute the hypothesis of an inverted u shaped ekc for transport co2 emissions in tunisia the findings of this study have a number of policy implications economic growth environmental degradation energy and transportation policies should be recognized in order to improve the energy efficiency in transport sector all measures that should reduce petroleum consumption and greenhouse gas emissions without affecting economic growth may be undertaken the policymakers in tunisia should plan urban transport relocate production units improve fuel efficient vehicles and reinforce legislation on controlling emissions in order to copying with policies based on low carbon development and climate resilient strategies

oil vulnerability index of oil importing countries abstract this paper assesses the relative oil vulnerability of 26 net oil importing countries for the year 2004 on the basis of various indicators the ratio of value of oil imports to gross domestic product gdp oil consumption per unit of gdp gdp per capita and oil share in total energy supply ratio of domestic reserves to oil consumption exposure to geopolitical oil market concentration risks as measured by net oil import dependence diversification of supply sources political risk in oil supplying countries and market liquidity the approach using the principal component technique has been adopted to combine these individual indicators into a composite index of oil vulnerability such an index captures the relative sensitivity of various economies towards developments of the international oil market with a higher index indicating higher vulnerability the results show that there are considerable differences in the values of individual indicators of oil vulnerability and overall oil vulnerability index among the countries both inter and intraregional

from the copenhagen accord to efficient technology protocols abstract as the copenhagen conference of parties cop failed to negotiate a binding post kyoto agreement an alternative is proposed based on the copenhagen accord ca the ca as endorsed by cop16 in cancun aims to combat global warming with differentiated reduction targets of greenhouse gas emissions and by mobilizing resources supporting adaptation and carbon free technology in developing countries dcs using a special version of merge we study the global implications of the ca postulating extensions of the accord in the direction of technology transfer protocols ttps we assess scenarios needed to reach sustainable climate targets under such protocols it is shown that without binding commitments for dcs the warming target of 2 c will be exceeded with a probability above 50 even if annex b countries eliminate their emissions however moderate commitments of dcs when they reach sufficient economic development make the 2 c scenario feasible ttps combined with binding emission reduction targets thus provide a mechanism to reduce climate change damages and may generate significant secondary benefits for example the reduced tax subsidy scenario rts20 has 77 to 40 chances to remain below 2 c of warming and an undiscounted cumulative gross domestic product gdp cost of 0 75 relative to baseline not accounting for the benefits of avoided damages

evaluating energy security in the asia pacific towards a more comprehensive approach the energy security conundrum how to equitably provide available affordable reliable efficient and environmentally benign energy services is a technology and policy challenge perhaps unlike any other the recent article on an energy security in the asia pacific by vlado vivoda is an excellent starting point for how to best capture the unique energy security challenges facing the region this article builds on vivoda s work but also points out some shortcomings with his analysis

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

are australia s tourism markets converging in this paper we make an important contribution towards understanding australia s tourism industry by examining whether or not australia s tourism markets are converging we define convergence as the reduction in tourist arrivals differential which is calculated as the difference between total visitor arrivals to a country and visitor arrivals from a particular tourist source market we analyze australia s thirteen major tourist source markets using monthly data over the period january 1991 to september 2003 to test for convergence we use the univariate and panel lagrange multiplier lm tests our main finding is that when we allow for two structural breaks in the data series both univariate and panel lm tests provide strong evidence for convergence of australia s tourism markets this implies that policies aimed at attracting visitor arrivals from any one of australia s thirteen tourist source markets will boost the volume of tourists coming into the country

carbon dioxide emissions and economic growth panel data evidence from developing countries in this paper we test the environment kuznet s curve ekc hypothesis for 43 developing countries we suggest examining the ekc hypothesis based on the short and long run income elasticities that is if the long run income elasticity is smaller than the short run income elasticity then it is evident that a country has reduced carbon dioxide emissions as its income has increased our empirical analysis based on individual countries suggests that jordan iraq kuwait yemen qatar the uae argentina mexico venezuela algeria kenya nigeria congo ghana and south africa approximately 35 per cent of the sample carbon dioxide emissions have fallen over the long run that is as these economies have grown emissions have fallen since the long run income elasticity is smaller than the short run elasticity we also examine the ekc hypothesis for panels of countries constructed on the basis of regional location using the panel cointegration and the panel long run estimation techniques we find that only for the middle eastern and south asian panels the income elasticity in the long run is smaller than the short run implying that carbon dioxide emission has fallen with a rise in income

world transport energy demand modelling methodology and elasticities abstract this paper presents the international energy agency s iea approach of modelling transport energy demand fuel demand which is not a demand per se is derived whenever possible from the economic activity in the transport sector and not estimated directly ie using one equation or simultaneous equation system in general the transport models employ a two step approach in the first step transport activity the sector s relevant energy service is estimated econometrically in the second step the transport activity projections are then combined with estimates of efficiency improvements car turnover rates and diesel gasoline penetration assumptions in order to arrive at projections of fuel demand the principal advantages of this approach are that the relevant energy services are modelled and that for model simulation efficiency improvements can be dealt with explicitly the effectiveness of economic instruments is a function of the reaction of consumers and businesses to income and price changes an in depth understanding of income and price elasticities of transport demand and transport energy demand is important in order to be able to assess the effectiveness of policies considered the paper also shows the underlying long term income and price elasticities for oecd and non oecd regions

energy consumption real income and temporal causality results from a multi country study based on cointegration and error correction modelling techniques abstract unlike previous studies on the causal relationship between energy consumption and economic growth this paper illustrates how the finding of cointegration i e long term equilibrium relationship between these variables may be used in testing granger causality based on the most recent johansen s multivariate cointegration tests preceded by various unit root or non stationarity tests we test for cointegration between total energy consumption and real income of six asian economies india pakistan malaysia singapore indonesia and the philippines non rejection of cointegration between variables rules out granger non causality and imples at least one way of granger causality either unidirectional or bidirectionial secondly by using a dynamic vector error correction model we then analyse the direction of granger causation and hence the within sample granger exogeneity or endogeneity of each of the variables thirdly the relative strength of the causality is gauged through the dynamic variance decomposition technique by decomposing the total impact of an unanticipated shock to each of the variables beyond the sample period into proportions attributable to shocks in the other variables including its own in the bivariate system results based on these tools of methodology indicate that while all pair wise relationships shared common univariate integrational properties only relationships for three countries india pakistan and indonesia were cointegrated for these countries temporal causality results were mixed with unidirectional causality from energy to income for india exactly the reverse for indonesia and mutual causality for pakistan the vdcs were not inconsistent with these results and provided us with an additional insight as to the relatively more dominant direction of causation in pakistan simple bivariate vector autoregressive models for the three non cointegrated systems did not indicate any direction of causality significantly in either direction

an investigation of co integration and causality between energy consumption and economic activity in taiwan applying hsiao a version of the granger causality method this paper examines the causality between energy and gnp and energy and employment by applying recently developed techniques of co integration and hsiao s version of the granger causality to taiwanese data for the 1955 1993 period the phillips perron tests reveal that the series with the exception of gnp are not stationary and therefore differencing is performed to secure stationarity the study finds causality running from gdp to energy consumption without feedback in taiwan it is also found that causality runs from gdp to energy but not vice versa

energy consumption and gdp causality relationship in g 7 countries and emerging markets abstract the causality relationship between energy consumption and income is a well studied topic in energy economics this paper studies the time series properties of energy consumption and gdp and reexamines the causality relationship between the two series in the top 10 emerging markets excluding china due to lack of data and g 7 countries we discover bi directional causality in argentina causality running from gdp to energy consumption in italy and korea and from energy consumption to gdp in turkey france germany and japan hence energy conservation may harm economic growth in the last four countries

how economic growth affects emissions an investigation of the environmental kuznets curve in portuguese and spanish economic activity sectors abstract it is a disquieting reality that increased economic growth for many years now in the western world is at odds with environmental degradation in this paper the relationship between economic growth and environmental variables is analyzed under two non linear specifications a quadratic and a cubic specification the study is conducted for portugal and spain in the period 1975 2012 using data for 13 sectors gva is used as proxy for income while energy use and carbon dioxide account for environmental degradation there is evidence for an inverted u shaped ekc however there are also other inverted n shaped functions that explain the relationship between economic growth and emissions altogether empirical results do indicate particular differences between portuguese and spanish sectors the results are of interest not only for researchers but also for policy makers political mitigation measures are also analyzed

stoking the fires co2 emissions and economic growth abstract we examine the relationship between economic development and carbon dioxide emissions a greenhouse gas central to global warming predictions estimates derived from global panel data suggest a diminishing marginal propensity to emit mpe carbon dioxide as gdp per capita rises despite this global carbon dioxide emissions growth will continue at 1 8 percent per annum for the foreseeable future a result that is not sensitive to average output growth instead emissions growth continues because output and population will grow most rapidly in lower income nations with high mpes this latter feature emphasizes the distributional consequences of policies to reduce emissions

evaluation of property tax bonus to promote solar thermal systems in andalusia spain abstract this paper evaluates the effects of a property tax bonus to promote the installation of solar thermal energy systems in buildings in andalusia southern spain the propensity score matching methodology is used the treatment group consists of municipalities of andalusia that established property tax bonuses in their municipalities in 2010 the control group consists of municipalities that did not the response variable measures the number of new square meters of solar thermal systems installed in 2010 the analysis leads to the conclusion that municipalities that established a property tax bonus had installed on average 102 245 to 122 389 square meters more these results indicate that the percentage increase in squares meters installed in municipalities which adopted the tax bonus promotion ranged from 70 74 to 98 38 these percentages were lower for rural municipalities 49 00 to 77 06

economic growth and transport energy consumption in the latin american and caribbean countries abstract transport is a strategic sector for economic development whilst being one of the most polluting sectors of the economy the latin american and caribbean countries have been consolidated as the region with significantly faster energy consumption growth this paper analyzes how the gdp per capita affects the transport energy consumption testing possible non linear relationships between variables a transport energy consumption function depending on gdp and its squared and cubed value is estimated for 22 lac countries over the period 1990 2014 the results support an n shaped curve while the elasticity values of transport energy consumption with respect to gdp per capita do not show a tendency to decrease in the long term fourteen lac countries show absolute coupling levels at the end of the period while the rest exhibit partial couplings likewise trade openness population density degree of urbanization and structural changes in the economy have positive effects on the transport energy consumption this paper proposes some energy efficiency measures to control the growing energy use and the promotion of biofuels and electric vehicles is also considered necessary to reduce the negative effects of transport energy use

economic growth and emissions reconsidering the empirical basis of environmental kuznets curves abstract recent empirical research indicates that certain types of emissions follow an inverted u or environmental kuznets curve ekc as income grows this regularity has been interpreted as a possible de linking of economic growth and patterns of certain pollutants for developed economies in this paper the empirical basis of this result is investigated by considering some statistical particularities of the various ekc studies performed it is argued that the inverted u relationship between income and emissions estimated from panel data need not hold for specific individual countries over time based on insights from intensity of use analysis in resource economics an alternative growth model is specified and estimated for three types of emissions co2 nox and so2 in four countries netherlands uk usa and western germany it is found that the time patterns of these emissions correlate positively with economic growth and that emission reductions may have been achieved as a result of structural and technological changes in the economy sustainable growth is defined as the rate of economic growth that does not lead to growth in emissions its rate is calculated for each type of emission and country based on estimated parameter values the resulting indicators reflect a balance between the positive influence of growth and negative influence of structural change and technological progress on emission levels

projection of future transport energy demand of thailand the objective of this study is to project transport energy consumption in thailand for the next 20 years the study develops log linear regression models and feed forward neural network models using the as independent variables national gross domestic product population and the numbers of registered vehicles the models are based on 20 year historical data between years 1989 and 2008 and are used to project the trends in future transport energy consumption for years 2010 2030 the final log linear models include only gross domestic product since all independent variables are highly correlated it was found that the projection results of this study were in the range of 54 84 59 05 million tonnes of oil equivalent 2 5 times the 2008 consumption the projected demand is only 61 65 of that predicted in a previous study which used the leap model this major discrepancy in transport energy demand projections suggests that projects related to this key indicator should take into account alternative projections because these numbers greatly affect plans policies and budget allocation for national energy management

assessing the energy vulnerability case of industrialised countries the emergence of new big consumer countries on the energy markets and the perspective of oil and gas depletion at the end of the current century raise the concerns about fair distribution of the remaining resources for the common and sustainable wellbeing of the mankind high volatility of energy prices discourages the investment and delays the energy technology transition voluntary measures are needed mainly in industrialised countries in order to develop alternative and sustainable energy sources to enable technology transfer towards emerging and developing countries and to avoid struggle for energy procurement in this paper a composite index of energy demand supply weaknesses is defined as a proxy of energy vulnerability the proposed index is based on several indicators such as energy intensity oil and gas import dependency co2 content of primary energy supply electricity supply weaknesses and non diversity in transport fuels the assessment of this composite index for selected industrialised countries is discussed as well as the sensitivity to various factors

reexamining the empirical evidence for an environmental kuznets curve this paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted u shaped relationship between national income and pollution we test the sensitivity of the pollution income relationship to functional forms to additional covariates and to changes in the nations cities and years sampled we find that the results are highly sensitive to these changes and conclude that there is little empirical support for an inverted u shaped relationship between several important air pollutants and national income in these data

price dispersion in an automobile insurance market from automobile insurance data for alberta over the period 1974 81 we find thatpremiums are highly correlated across driver classes in a given year but that premiums for a given driver class are not correlated over a period of more than 5 years firms relative market shares among drivers over age 25 and married males under 25 are inversely related to their deviations from the mean premiums in these driver classes the variance of real premiums decreases with the numberof firms in the market and increases with the real loss cost per car insured and the number of cars insured from these results we conclude that the price dispersion in automobile insurance in alberta is based on costly consumer search

number of sellers average prices and price dispersion abstract a variety of models provide differing predictions regarding the effect of an increase in the number of competitors in a market seller density on prices and price dispersion we review different approaches to generating equilibrium price dispersion and then empirically estimate the relationship between seller density average product price and price dispersion in the retail gasoline industry using four unique gasoline price data sets controlling for station level characteristics we find that an increase in station density consistently decreases both price levels and price dispersion across four geographical areas

revisiting the convergence hypothesis for tourism markets evidence from turkey using the pairwise approach abstract this paper empirically revisits the tourism markets convergence hypothesis narayan 2006 for the case of turkey by employing the newly developed pairwise approach to the analysis of stochastic convergence pesaran 2007 pesaran et al 2009 this new approach allows for unit root tests to be conducted on all possible pairs of tourist arrival differentials across turkey s 20 major tourist source markets thus avoiding the need to choose a base source market or total tourist arrivals figure as the benchmark using monthly data over the period january 1996 to december 2009 the main finding is that despite considerable co movement of international tourist arrivals in turkey there is no evidence of long run convergence among turkey s major tourism markets cluster based club convergence analyses alongside bivariate pairwise estimations confirm the lack of convergence and highlight specific tourist source markets with considerable untapped potential these findings have profound policy implications for turkey s inbound tourism planning and promotion

is there an environmental kuznets curve for deforestation abstract this paper examines the relationship between deforestation and gross domestic product gdp per capita in particular whether an inverted u relationship indicative of worsening then improving deforestation exists between them we note that previous work has used models with restrictive assumptions and recommend a more flexible random coefficients specification which allows for a greater degree of cross country heterogeneity empirical results using data for 76 developing countries between 1961 1992 suggest that the inverted u shaped relationship observed in other studies does not appear to be an empirical regularity with our less restrictive specification statistical tests indicate that this specification is supported by the data we argue that such results are not surprising in view of the wide diversity of physical and social characteristics that exist across countries

energy models for demand forecasting a review abstract energy is vital for sustainable development of any nation be it social economic or environment in the past decade energy consumption has increased exponentially globally energy management is crucial for the future economic prosperity and environmental security energy is linked to industrial production agricultural output health access to water population education quality of life etc energy demand management is required for proper allocation of the available resources during the last decade several new techniques are being used for energy demand management to accurately predict the future energy needs in this paper an attempt is made to review the various energy demand forecasting models traditional methods such as time series regression econometric arima as well as soft computing techniques such as fuzzy logic genetic algorithm and neural networks are being extensively used for demand side management support vector regression ant colony and particle swarm optimization are new techniques being adopted for energy demand forecasting bottom up models such as markal and leap are also being used at the national and regional level for energy demand management

long term outlook of energy use and co2 emissions from transport in central and eastern europe a forecast of transport activity energy consumption and carbon dioxide emissions from transportation carried out under business as usual economic assumptions is presented for the 10 countries of central and eastern europe that have acquired the status of accession countries to the european union energy demand is projected under considerations of the dynamic evolution of transport modes and their use the evolution of automotive fuel prices which are assumed to gradually converge with western european price levels within the current decade and assumptions on efficiency improvements in all transport modes according to current technological trends and european regulations the results showing transportation energy demand to double and co2 emissions to be 70 higher in 2030 compared to 2000 are compared with other published forecasts and discussed with a view to potential future energy and environmental impacts in these countries outlining major policy implications r 2002 elsevier science ltd all rights reserved

relationship between level of economic development and motorcycle and car ownerships and their impacts on fuel consumption and greenhouse gas emission in thailand abstract an increase in road vehicles secondary to economic development has strongly pushed up energy demand and adversely impact the environment by the emission of greenhouse gases and pollutants this paper aims to analyse the relationship between motorcycle and car ownerships and level of economic development in thailand in addition an overall private vehicle ownership which is a sum of both types of private vehicle ownership is also studied an understanding of these relationships due to the economic development is a key knowledge for the sustainable transport policy in the future the results of this study revealed that at the early stage of economic development of developing countries like thailand the number of motorcycles predominates over private cars economic development strongly affects the ownership of private vehicles in two ways 1 overall private vehicle ownerships increase as the income levels grow and 2 after personal income grows up to a certain level people will shift from motorcycle to car ownerships for their prestige convenience comfort and safety because of continuing economic development and population growth the expected increase in overall private vehicle ownership is projected to push up the total private vehicle stock of thailand in the year 2050 to about twice of the present level this will drive fuel demands in 2050 to about 2 4 times and the greenhouse gases ghg emission to about 2 5 times of the current levels hence policy makers in developing countries should not overlook the impacts on the consequences of increasing overall private vehicle stock in the near future the best and most appropriate policies should be given to the development of public transport as the first priority rather than the traditional one which gives highest priority to traffic mobility of private vehicles by road transport neglecting the effectiveness of passengers mobility of the public transport in addition policies to promote high efficiency vehicle technologies particularly for motorcycles should also be taken into consideration particularly for a low income country due to a high share of the motorcycles in the overall private vehicle stock

empirical assessment of the determinants of road energy demand in greece this paper attempts to cast light on the determinants of road energy demand in greece for this purpose we used cointegration techniques and vector autoregression var analysis in order to capture short run and long run dynamics for gasoline and diesel demand respectively from the empirical analysis that covers the period 1978 2003 we find that in the long run gasoline energy demand appears to be price and income inelastic while diesel demand appears to be price inelastic and income elastic we also found that the absence of close substitutes in the road sector denotes the low level of energy switching in greece

low carbon society scenario analysis of transport sector of an emerging economy the aim enduse modelling approach abstract the transport sector of a country is the backbone driving the economy forward thailand s land transport sector is modelled using the aim enduse which is a recursive dynamic optimization model based on bottom up modelling principle the travel demand is divided into two major categories which are passenger travel and freight travel the objective of this paper is to analyse the mitigation possible through low carbon society lcs measures and emission tax et two scenario clusters are devised along with the bau case the lcs scenario cluster has three designed scenarios which are lcs l lcs m and lcs h the emission tax et cluster has four scenarios where the taxes of 50 100 200 and 500 usd t co2 are implemented along with this the marginal abatement costs mac of the counter measures cms and the co benefits in terms of energy security productivity and air pollutant mitigation are also assessed results show that lcs scenarios are possible of mitigating up to 1230 mt co2 cumulatively from 2010 to 2050 in terms of macs new vehicles play a pivotal role along with hybrid vehicles the average abatement cost aac assessment shows that the aac of lcs h scenario is in the order of 100 usd t co2 all the lcs and et scenarios show an enhancement in energy security and also a threefold increase in productivity there is distinct mitigation in terms of air pollutants from the transport sector as well

economic growth and atmospheric pollution in spain discussing the environmental kuznets curve hypothesis abstract the environmental kuznets curve ekc hypothesis posits an inverted u relationship between environmental pressure and per capita income recent research has examined this hypothesis for different pollutants in different countries despite certain empirical evidence showing that some specific environmental pressures have diminished in developed countries the hypothesis could not be generalized to the global relationship between economy and environment at all in this article we contribute to this debate analyzing the trends of annual emission flux of six atmospheric pollutants in spain the study presents evidence that there is not any correlation between higher income level and smaller emissions except for so2 whose evolution might be compatible with the ekc hypothesis the authors argue that the relationship between income level and diverse types of emissions depends on many factors thus it cannot be thought that economic growth by itself will solve environmental problems

dynamic linkages among transport energy consumption income and co2 emission in malaysia this paper examines the dynamic relationship between income energy use and carbon dioxide co2 emissions in malaysia using time series data during 1975 to 2011 this study also attempts to validate the environmental kuznet curve ekc hypothesis applying a multivariate model of income energy consumption in the transportation sector carbon emissions structural change in the economy and renewable energy use the empirical evidence confirmed that there is a long run relationship between the variables as shown by the result of co integration analysis the results indicate that the inverted u shape ekc hypothesis does not fully agree with the theory the coefficient of squared gdp is not statistically different from zero the time duration and the annual data used for the present study do not seem to strongly validate the existence of ekc hypothesis in the case of malaysia causality test shows that the relationship between gdp and co2 is unidirectional the granger causality test results reveal that emissions granger cause income energy consumption and renewable energy use moreover we find that income granger causes energy consumption and renewable energy use and both structural change and renewable energy use granger cause energy consumption in road transportation

the demand for gasoline in south africa an empirical analysis using co integration techniques abstract using the recently developed autoregressive distributed lag ardl bound testing approach to co integration suggested by pesaran et al pesaran m h shin y smith r j bounds testing approaches to the analysis of level relationships journal of applied econometrics 2001 16 3 289 326 we empirically analyzed the long run relationship among the variables in the aggregate gasoline demand function over the period 1978 2005 our study confirms the existence of a co integrating relationship the estimated price and income elasticities of 0 47 and 0 36 imply that gasoline demand in south africa is price and income inelastic

on the causal nexus of road transport co2 emissions and macroeconomic variables in tunisia evidence from combined cointegration tests abstract this paper investigates the causal relationship between road transportation energy consumption fuel prices transport sector value added and co2 emissions in tunisia for the period of 1980 2012 we apply the newly developed combined cointegration test proposed by bayer c hanck c combining non cointegration tests j time ser anal 2013 34 1 83 95 and the ardl bounds testing approach to cointegration for establishing the existence of long run relationship in presence of structural breaks the direction of causality between these variables is determined via vector error correction model vecm our empirical exercise reveals that cointegration is present energy consumption adds in co2 emissions fuel prices decline co2 emissions road infrastructure boosts co2 emissions transport value added also increases co2 emissions the causality analysis indicates the bidirectional casual relationship between energy consumption and co2 emissions road infrastructure causes co2 emissions and similar is true from opposite side in granger sense the bidirectional causality is also found between transport value added and co2 emissions fuel prices cause co2 emissions energy consumption road infrastructure and transport value added in granger sense this paper provides new insights to policy makers for designing a comprehensive energy transport and environment policies for sustainable economic growth in long run

a household level environmental kuznets curve abstract richer households may create more vehicle emissions because they own more vehicles and drive more poorer households may pollute more because they use high polluting vintages and maintain them less well this paper uses 1993 california vehicle microdata to show that there is a kuznets u shaped hydrocarbon emissions relation

investigating the causal relationship between transport infrastructure transport energy consumption and economic growth in tunisia this study investigates the causal relationships between transportation infrastructure rail and road the transport value added gross capital formation transportation energy consumption and transport co2 emissions in tunisia over the period of 1971 2012 we use the johansen multivariate cointegration approach generalized impulse response functions and variance decomposition technique to examine the effect of transportation infrastructure on economic growth and the environment these findings show the existence of unidirectional long run causality running from transport value added road transport related energy consumption transport co2 emissions and gross capital formation to road infrastructure it also finds a unidirectional long run causality running from railway infrastructure the transport value added gross capital formation and transport co2 emissions to rail transport related energy consumption besides we find a unidirectional short run causality running from the road infrastructure to transport value added and a unidirectional short run causality running from road transport related energy consumption to transport co2 emissions furthermore there are unidirectional short run causality running from railway infrastructure to rail transport related energy consumption and a unidirectional short run causality running from transport co2 emissions to rail transport related energy consumption these results are very important in terms of the choice of government policy decisions our results cast a new dimension to the importance of investing in infrastructure as a promising device to generate higher economic growth

examining carbon emissions economic growth nexus for india a multivariate cointegration approach abstract the study probes cointegration and causality between carbon emissions and economic growth for india using ardl bounds testing approach complemented by johansen juselius maximum likelihood procedure in a multivariate framework by incorporating energy supply investment and employment for time span 1971 2006 the study fails to establish long run equilibrium relationship and long term causality between carbon emissions and economic growth however there exists a bi directional short run causality between the two hence in the short run any effort to reduce carbon emissions could lead to a fall in the national income this study also establishes unidirectional short run causality running from economic growth to energy supply and energy supply to carbon emissions the absence of causality running from energy supply to economic growth implies that in india energy conservation and energy efficiency measures can be implemented to minimize the wastage of energy across value chain such measures would narrow energy demand supply gap absence of long run causality between carbon emissions and economic growth implies that in the long run focus should be given on harnessing energy from clean sources to curb carbon emissions which would not affect the country s economic growth

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

energy consumption and gdp in tunisia cointegration and causality analysis abstract in this paper the johansen cointegration technique is used to examine the causal relationship between per capita energy consumption pcec and per capita gross domestic product pcgdp for tunisia during the 1971 2004 period in order to test for granger causality in the presence of cointegration among the variables a vector error correction model vecm is used instead of a vector autoregressive var model our estimation results indicate that the pcgdp and pcec for tunisia are related by one cointegrating vector and that there is a long run bi directional causal relationship between the two series and a short run unidirectional causality from energy to gross domestic product gdp the source of causation in the long run is found to be the error correction terms in both directions hence an important policy implication resulting from this analysis is that energy can be considered as a limiting factor to gdp growth in tunisia conclusions for tunisia may also be relevant for a number of countries that have to go through a similar development path of increasing pressure on already scarce energy resources

energy consumption and economic growth the case of oil exporting countries this paper examines the causal relationship between the per capita energy consumption and the per capita gdp in a panel of 11 selected oil exporting countries by using panel unit root tests and panel cointegration analysis the results show a unidirectional strong causality from economic growth to energy consumption for the oil exporting countries the findings have practical policy implications for decision makers in the area of macroeconomic planning in most major oil exporting countries government policies keep domestic prices bellow free market level resulting in high levels of domestic energy consumption the results imply that the energy conservation through reforming energy price policies has no damaging repercussions on economic growth for this group of countries

benefits of low carbon development in a developing country case of nepal this paper analyzes the direct and indirect benefits of reducing co2 emission during 2005 to 2100 in the case of nepal a low income developing country rich in hydropower resource it discusses the effects on energy supply mix local pollutant emissions energy security and energy system costs of co2 emission reduction targets in the country by using an energy system model based on the markal framework the study considers three cases of co2 emission reduction targets and analyzes their benefits during the study period as compared to the reference scenario the first two cases consist of a 20 cutback scenario ert20 and 40 cutback scenario ert40 of co2 emission in the reference scenario the third case considers a 40 cutback of co2 emission with the share of electric mass transport emt in the land transport service demand increased to 30 as compared to 20 in the reference scenario the study shows that an implementation of scenario ert40 would increase the cumulative electricity generation mainly from hydropower by 16 5 794 twh reduce the cumulative consumption of imported fuels by 42 24 400 pj and increase the total energy system cost by 1 6 during 2005 to 2100 as compared to the reference scenario besides there would be a reduction in the emission of local pollutants and generation of additional employment in the country with the share of emt increased to 30 there would be a further reduction in local pollutant emissions an improvement in energy security and a decrease in the energy system cost compared to that in scenario ert40

assessing co2 emissions in china s commercial sector determinants and reduction strategies abstract the commercial sector is one of the key sectors in china s economic transformation and carbon emissions control this paper applies var and stirpat models to investigate the major influencing factors of co 2 emissions in china s commercial sector over the period 1980 2014 according to the empirical results per capita gdp urbanization and energy structure have positive effects on co 2 emissions while energy intensity has negative effect on co 2 emissions in the long term besides per capita gdp ranks as the most important driving factors of co 2 in china s commercial sector followed by urbanization energy structure and energy intensity in that order this paper argues that reducing energy intensity and improving energy structure are the means to realize co 2 emission reductions in the commercial sector in the short and long term respectively besides this paper forecasts that co 2 emissions in china s commercial sector will be 1942 mt by 2030 which is huge and about half of the co 2 emissions of the european union in 2014 the findings have important implications for policy makers to enact co 2 emission reduction policies

causality between energy consumption and economic growth in india a note on conflicting results abstract this note examines the different direction of causal relation between energy consumption and economic growth in india applying engle granger cointegration approach combined with the standard granger causality test on indian data for the period 1950 1996 we find that bi directional causality exists between energy consumption and economic growth further we apply johansen multivariate cointegration technique on the different set of variables the same direction of causality exists between energy consumption and economic growth this is different from the results obtained in earlier studies

estimating the effect of urban density on fuel demand much of the empirical literature on fuel demand presents estimates derived from national data which do not permit any explicit consideration of the spatial structure of the economy intuitively we would expect the degree of spatial concentration of activities to have a strong link with transport fuel consumption the present paper addresses this theme by estimating a fuel demand model for urban areas to provide a direct estimate of the elasticity of demand with respect to urban density fuel demand per capita is decomposed into car stock per capita fuel consumption per kilometre and annual distance driven per car per year urban density is found to affect fuel consumption mostly through variations in the car stock and in the distances travelled rather than through fuel consumption per kilometre

energy consumption employment output and temporal causality evidence from taiwan based on cointegration and error correction modelling techniques in this study a cointegration analysis and a vector autoregressive model var are used to examine the causal relationships among energy consumption employment and output for taiwan over the period january 1982 to november 1997 johansen 1988 and johansen and juselius 1990 cointegration test result indicates these three variables are cointegrated with one cointegrating vector the results from granger causality tests based on vector error correction models vecm suggest bidirectional grange causality for employment output and employment energy consumption but only unidirectional causality running from energy consumption to output furthermore the impulse responses and variance decompositions are also incorporated into the analysis the results from impulsive response and variance decomposition analysis tell similar stories energy consumption appears to have led to output growth in taiwan over this period the policy implication of this finding is that energy conservation will restrain the outpu

the independent submarkets model an application to the spanish retail banking market abstract the aim of this paper is to test the predictions of sutton s independent submarkets model with data on the spanish retail banking market the prediction of this model for aggregates of submarkets is that the form of equilibrium outcome must involve some minimal degree of size inequality however within each submarket when three conditions hold the only form of equilibrium outcome will be an extreme fragmented structure to test these predictions firstly i propose methods to identify independent submarkets then i analyze the degree of inequality in bank sizes for markets with different levels of aggregation submarkets regions and national market using concentration by towns data i find that in single submarket towns the degree of inequality of the size among banks is zero moreover multimarket towns with a significant degree of concentration are shown to be formed by a different number of independent submarkets where each bank owns one branch nonetheless when the regional and the national bank markets are considered the degree of inequality in bank sizes becomes high these results are consistent with the predictions of the theoretical model

latent submarket dynamics and industry evolution lessons from the us laser industry in its first 35 years the us laser industry was characterized by steady growth in output and the number of producers whereas subsequently the number of producers steadily declined despite continued growth in the industry s output a model of industry evolution that features the creation destruction and fusing of independent submarkets is developed to explain these two eras data on all laser producers are used to test various implications of the model concerning entry exit and innovation the findings suggest that the emergence of an integrative submarket can fundamentally alter an industry s market structure and the character of innovation which is applied to explain historical developments in the evolution of various innovative industries

road transport energy demand in australia a cointegration approach abstract a cointegration framework is used to examine the short run and long run characteristics of energy demand in the australian road transport sector a lagged endogenous equation based on a partial adjustment process is proposed and estimated results indicate that energy demand output and real energy prices are integrated of order 1 and cointegrated the long run output and price elasticities of energy demand are estimated to be 0 52 and 0 12 respectively causality tests ervealed a bidirectional causality path between output and energy demand and a unidirectional path from energy consumption to prices no other causality paths between output prices and energy demand are detected the short run output elasticity of energy demand is estimated to be 0 25 based on an error correction model the short run price elasticity is found to be insignificant the inertia parameter is 0 48 corresponding to 95 of the demand adjustment occurring after five periods the results are compared with previous findings and the variations are partially attributed to the structural changes in the road transport sector in the 1980s some of which are discussed

testing the transport energy environmental kuznets curve hypothesis in the eu27 countries abstract transport activities are essential for economic and social development nevertheless the transport sector has also shown the fastest growth in energy consumption in the european union and its contribution to increasing greenhouse gas emissions merits the thorough attention of academics and policy makers in this paper we analyze the relationship of economic growth and transport activities with transport final energy consumption energy kuznets curves are estimated for a panel data set covering the eu27 countries in the period 1995 2009 for total transport energy use household transport energy use and productive transport energy use all three in absolute and per capita energy use terms the productive transport energy use and gross value added relationship are further considered as per hour worked finally the control variables of energy prices and differences in the economic structures are tested empirical results show that the elasticity of transport energy use with respect to gross value added in per capita terms decreases from a threshold for the three transport energy consumption variables but the turning point of improved environmental quality is not reached in any instance

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

energy policies for low carbon sustainable transport in asia abstract transformation of asia s transport sector has vital implications for climate change sustainable development and energy indicators papers in this special issue show how transport transitions in asia may play out in different socio economic and policy scenarios including a low carbon scenario equivalent to 2 c stabilization accounting for heterogeneity of national transport systems these papers use diverse methods frameworks and models to assess the response of the transport system to environmental policy such as a carbon tax as well as to a cluster of policies aimed at diverse development indicators the analysis shows that co2 mitigation in a transport system is achieved more effectively by aligning mitigation policies with sustainable development policies and measures such as mandates for mode share and choices such as urban design information and communication systems and behavioral measures authors therefore advocate policies that target multiple dividends vis a vis carbon mitigation energy security and local air quality whereas four papers focus on emissions mitigation policies one paper examines challenges to adapt fast growing transport infrastructures to future climate change induced risks collectively the papers exemplify a set of policies and measures that can deliver co benefits and also demonstrate the use of methods frameworks and models to delineate the optimal mix of such policies and measures

the applicability of marginal abatement cost approach a comprehensive review abstract the marginal abatement cost mac methodology is widely used in climate change policies policy makers rely on mac to assess feasible strategies and related costs to achieve emission reduction goals this paper introduces a variety of mac methodologies aiming at solving diverse problems which utilizes various calculable logic thus producing different results and implications this study applies a mind mapping method to capture differentiation of mac methods and systematically classify mac methodologies the applicability path analysis was proposed based on principles such as stakeholder type decision making objectives cost concept strategy mode and information scope our goal is to assess the applicability of different methodologies to reduce misuse by policy makers and to serve as a guide for subsequent research which might prompt and lead to the derivation of more consequential results in future studies the results of this study suggest that the complex method is not always better than the simplified method because policy makers are required to select the appropriate method according to the type of information needed it may even be suggested that mac could be reliable by ranking relative value of options compared with baseline rather than focusing on the absolute value of individual measures

decomposing road freight energy use in the united kingdom applying the techniques of decomposition analysis we estimate the relative contribution of ten variables termed key ratios plus gdp to the change in uk road freight energy use over the period 19892004 inclusive the results are best interpreted as an estimate of the percentage growth in energy consumption that would have resulted from the change in the relevant factor e g length of haul had the other factors remained unchanged the results demonstrate that the main factor contributing to the decoupling of uk road freight energy consumption from gdp was the decline in the value of domestically manufactured goods relative to gdp over the period 19892004 this largely offset the effect of increases in gdp on road freight energy consumption while the decline in domestic manufacturing was to some extent displaced by increases in imports the net effect of these supply factors together with shifts in the commodity mix has been to reduce uk road freight energy consumption by 30 1 the net effect on global carbon dioxide co2 emissions is likely to be somewhat less beneficial since many freight movements associated with the manufacture of imported goods have simply been displaced to other countries

energy consumption and gdp in turkey is there a co integration relationship energy consumption and gdp are expected to grow by 5 9 and 7 annually until 2025 in turkey this paper tries to unfold the linkage between energy consumption and gdp by undertaking a co integration analysis for turkey with annual data over the period 1970 2003 the analysis shows that energy consumption and gdp are co integrated this means that there is a possibly bi directional causality relationship between the two we establish that there is a unidirectional causality running from gdp to energy consumption indicating that energy saving would not harm economic growth in turkey in addition we find that energy consumption keeps on growing as long as the economy grows in turkey

exploring the regional distribution of tourism and the extent to which there is convergence abstract in this paper we test the hypothesis of convergence in a set of twelve of the main tourism source markets of spain over a time period that ranges from january 2000 to september 2015 we analyse the potential convergence by following an econometric strategy consisting of three different methodologies firstly we test for the presence of full convergence in the dataset by means of the panel stationary test developed by hadri 2000 next we conduct a robustness check for the full convergence hypothesis by considering the potential existence of structural breaks in the dataset through the test proposed by carrion i silvestre et al 2005 finally the hypothesis of club convergence philips and sul 2007 is also tested the results point to absence of full convergence even when controlling for structural breaks while three different clubs of convergence are found we discuss potential policy implications that can be extracted from these results

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

co2 emissions energy consumption and output in france abstract this paper examines the dynamic causal relationships between pollutant emissions energy consumption and output for france using cointegration and vector error correction modelling techniques we argue that these variables are strongly inter related and therefore their relationship must be examined using an integrated framework the results provide evidence for the existence of a fairly robust long run relationship between these variables for the period 1960 2000 the causality results support the argument that economic growth exerts a causal influence on growth of energy use and growth of pollution in the long run the results also point to a uni directional causality running from growth of energy use to output growth in the short run

energy consumption income and carbon emissions in the united states abstract this paper investigates the effect of energy consumption and output on carbon emissions in the united states earlier research focused on testing the existence and or shape of an environmental kuznets curve without taking energy consumption into account we investigate the granger causality relationship between income energy consumption and carbon emissions including labor and gross fixed capital formation in the model we find that income does not granger cause carbon emissions in the us in the long run but energy use does hence income growth by itself may not become a solution to environmental problems

firm size distribution testing the independent submarkets model in the italian motor insurance industry this paper tests the presence of multiple independent submarkets in the italian motor insurance industry independence is motivated by administrative boundaries among provinces and by further locational reasons we find that the independence effects are sufficient to induce a minimum degree of inequality in the size distribution of firms once submarkets are aggregated these results are fully consistent with the predictions of sutton 1998 we also show that the degree of skewness in the firms size distribution is related to characteristics such as the population living in an area its density and the riskiness of a submarket

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment
