empirical study on the determinants of co2 emissions evidence from oecd countries this article empirically investigates the environmental kuznets curve ekc for co2 emissions in the cases of 11 oecd countries by taking into account the role of nuclear energy in electricity production the autoregressive distributed lag approach to cointegration is employed as the estimation method our results indicate that energy consumption has a positive impact on co2 emissions in most countries in the study however the impact of trade is not statistically significant the results provide evidence for the role of nuclear power in reducing co2 emissions only in some countries additionally although the estimated long run coefficients of income and its square satisfy the ekc hypothesis in finland japan korea and spain only finland s ekc turning point is inside the sample period of the study providing poor evidence in support of the ekc hypothesis

the environmental consequences of globalization a country specific time series analysis abstract the dynamic relationships among trade income and the environment for developed and developing countries are examined using a cointegration analysis results suggest that trade and income growth tend to increase environmental quality in developed countries whereas they have detrimental effects on environmental quality in most developing countries it is also found that for developed countries the causal relationship appears to run from trade and income to the environment a change in trade and income growth causes a consequent change in environmental quality for most developing countries on the other hand the causality is found to run from the environment to trade and income however the opposite causal relationship holds for china

contingent commodities and implementation abstract in this note we study the relevance of using contingent commodity allocations when states are not directly contractible in such a setting a contingent commodity allocation takes the form of a social choice function and the question is whether this function is implementable using only very mild assumptions on the rule for selecting contingent commodity allocations we derive a strong negative result which proves to be robust with respect to different solution concepts employed for implementation these findings have interesting implications for the interpretation of arrow debreu economies

is there a turning point in the relationship between income and energy use and or carbon emissions abstract we analyze the effect of fuel mix model specification and the level of development on the presence and size of a turning point in the relationship between income and energy use and or carbon emissions the results indicate that fuel mix the specification for income and the level of economic development affect conclusions about whether there is a turning point in the relationship between economic activity and energy use and carbon emissions including fuel shares generally reduces the size of a turning point that is estimated from a panel that includes observations from both oecd and non oecd nations but this result varies according to the level of development for oecd nations there is limited support for a turning point in the relationship between income and per capita energy use and or carbon emissions for non oecd nations there is no turning point in the relationship between income and either energy use or carbon emissions instead the relationship is positive together the results indicate that forecasters and policy makers should not depend on a turning point in the relationship between income and energy use or carbon emissions to reduce either

the role of market forces in assuring contractual performance the conditions under which transactors can use the market repeat purchase mechanism of contract enforcement are examined increased price is shown to be a means of assuring contractual performance a necessary and sufficient condition for performance is the existence of price sufficiently above salvageable production costs so that the nonperforming firm loses a discounted steam of rents on future sales which is greater than the wealth increase from nonperformance this will generally imply a market price greater than the perfectly competitive price and rationalize investments in firm specific assets advertising investments thereby become a positive indicator of likely performance

the divergence of japanese and u s corporate financial structure a comparison of the balance sheet structure of the largest u s and japanese firms for 1979 shows that japanese firms significantly differ from u s firms in their greater reliance on bank funded short term debt low levels and composition of net working capital parsimonious use of stockholder s equity and greater commitment to long term investments in other corporations

incomplete contracts and strategic ambiguity why are observed contracts so often incomplete in the sense that they leave contracting parties obligations vague or unspecified traditional answers to this question invoke transaction costs or bounded rationality in contrast the authors argue that such incompleteness is often an essential feature of a well designed contract specifically once some aspects of performance are unverifiable it is often optimal to leave other verifiable aspects of performance unspecified the authors explore the conditions under which this occurs and investigate the structure of optimal contracts when these conditions are satisfied copyright 1998 by american economic association

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

environmental kuznets curve for co2 emissions the case of arctic countries abstract the main new contribution of this paper is to examine the environmental kuznets curve ekc hypothesis using time series data at individual country levels empirical focus is on the assessment of income per capita on co 2 emissions in the arctic countries by taking into account the role of energy consumption an autoregressive distributed lag ardl modeling approach to cointegration is applied to annual data for the period 1960 2010 the results provide little evidence of the existence of the ekc hypothesis for the arctic countries we also find that economic growth has a beneficial effect on the environment only in some arctic countries finally energy consumption is found to have a detrimental effect on the environment in most countries

subjective performance measures in optimal incentive contracts objective measures of performance are seldom perfect in response incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures this paper explores the combined use of subjective and objective performance measures in respectively implicit and explicit incentive contracts naturally objective and subjective measures often are substitutes sometimes strikingly so we show that if objective measures are sufficiently close to perfect then no implicit contracts are feasible because the firm s fallback position after reneging on an implicit contract is too attractive we also show however that objective and subjective measures can reinforce each other if objective measures become more accurate then in some circumstances the optimal contract puts more weight on subjective measures because the improved objective measures increase the value of the ongoing relationship and so reduce the firm s incentive to renege we also analyze the use of subjective weights on objective performance measures and provide case study evidence consistent with our analyses

economic growth and energy consumption the energy environmental kuznets curve for latin america and the caribbean abstract this paper investigates the relationship between economic growth and energy consumption using the hypothesis postulated for the energy environmental kuznets curve which assumes an inverted u shape relationship between income and energy consumption panel data for 22 latin american and caribbean countries for the period 1990 2011 were used absolute energy consumption was chosen as an environmental pressure indicator because energy consumption is the major contributor of emissions pollutants the results obtained in the estimations show that the hypothesis postulated for the energy environmental kuznets curve is not supported for the region on the contrary the results show an exponential growth as gross value added grows also notable differences are shown between the analyzed economies

testing the kuznets curve hypothesis for qatar a comparison between carbon dioxide and ecological footprint abstract this paper explores the validity of the environmental kuznets curve ekc using two different environment indicators the carbon dioxide emissions co2 and the ecological footprint ef in qatar over the 1980 2011 period to this end we investigate the impact of real gross domestic product rgdp the square of rgdp the energy use the financial development and the trade openness on the co2 emissions and the ef we employ the autoregressive distributed lag ardl model with the presence of unknown structural breaks in order to study short run and long run elasticity between the variables the findings infer that there is a long run relationship among the selected variables with a shift in the cointegration vector in 1991 and 2000 the empirical result indicates that the inverted u shaped hypothesis is not valid in qatar when we use the co2 emissions whereas the inverted u shaped held when using the ef furthermore the error correction results confirm that the convergence towards the long run equilibrium will mostly occur within one year after a short run shock generally the findings suggest that qatar should invest more in efficient energy and continue sustained its growth moreover more efforts are needed for diversification particularly in technology intensive and environment friendly industries to improve environmental quality

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

transaction costs and contractual incompleteness the case of electricite de france abstract this paper explores the incompleteness of inter firm contracts through the lens of recent developments in transaction cost economics we built a non truncated contract database representing all the relationships of electricite de france edf with its coal carriers over the period 1977 1997 we tested and corroborated most propositions derived from transaction cost theory relating contractual incompleteness to transaction characteristics even when we considered the complete set of the theory s propositions by endogeneizing the asset specificity at stake in transactions to our knowledge this kind of test has never been conducted before

cheap talk and bogus network externalities in the emerging technology market many emerging technologies exhibit path dependent demands driven by positive network feedback such network effects profoundly impact marketing strategists thinking in today s network economy however the significant network externalities expected by many people often fail to materialize in the emerging technology market we analyze this phenomenon in the context of a technology distribution channel by studying cheap talk strategies under information asymmetry we show that incentive compatible contracts are essential for achieving credible information transmission in our model the better informed technology vendor has an incentive to inflate the retailer s ex ante belief of network externalities when a wholesale price contract is adopted when properly termed revenue sharing contracts are implemented there are information efficient cheap talk equilibria where truthful information transmission is mutually beneficial when the vendor s information is imperfect even revenue sharing contracts cannot guarantee credible information transmission if there is significant prior belief disparity between the vendor and the retailer this study demonstrates how information inefficient equilibria e g information blockage arise because of the conflict of interest or the conflict of opinion among channel members it also explores the role of cheap talk in facilitating channel coordination

information and the hold up problem we examine situations in which a party must make a sunk investment prior to contracting with a second party to purchase an essential complementary input we study how the resulting hold up problem is affected by the seller s information about the investing party s likely returns from its investment our principal focus is on the effects of the investment s being observable by the non investing party contrary to popular intuition we find that an improvement in the seller s information e g the investment s being observable rather than not can benefit the buyer and harm the seller we also find that other popular intuitions about this problem are either false incomplete or require strong assumptions to be valid

is economic growth good or bad for the environment empirical evidence from korea abstract the effects of economic growth on the environment in korea for a given level of energy consumption and fossil fuels and nuclear energy in electricity production are examined in a dynamic cointegration framework to that end the autoregressive distributed lag ardl approach is used we find empirical evidence supporting the existence of the environmental kuznets curve ekc hypothesis for korea that is economic growth indeed plays a favorable role in influencing environmental outcomes it is also found that in both the short and long run nuclear energy has a beneficial effect on environmental quality whereas fossil fuels in electricity production and energy consumption have a detrimental effect on the environment

relational incentive contracts standard incentive theory models provide a rich framework for studying informational problems but assume that contracts can be perfectly enforced this paper studies the design of self enforced relational contracts i show that optimal contracts often can take a simple stationary form but that self enforcement restricts promised compensation and affects incentive provision with hidden information it may be optimal for an agent to supply the same inefficient effort regardless of cost conditions with moral hazard optimal contracts involve just two levels of compensation this is true even if performance measures are subjective in which case optimal contracts terminate following poor performance jel c73 d82 l14

the econometric consequences of an energy consumption variable in a model of co2 emissions abstract many studies that model the determinants of co 2 emissions treat energy consumption as one of its determinants itkonen 2012 argues that this causes underestimation of both the responsiveness of co 2 emissions to income growth and the turning point of the carbon kuznets curve we first demonstrate that itkonen s 2012 conclusions are sensitive to the assumed form of the relationship between energy consumption and income we then argue that the presence of an energy consumption variable in a model of co 2 emissions can lead to systematic volatility in its coefficients which has the potential to change their magnitude and sign we also argue that misleading cointegration test results can be generated by such a model the potential nature and severity of these effects are illustrated with data for seven countries

on the income nuclear energy co2 emissions nexus revisited this paper seeks to contribute to the debate over the income nuclear enery co2 emissions nexus by taking specific account of the possible endogeneity of income which has been largely ignored by early studies a multivariate cointegrated vector autoregression cvar is applied to top six nuclear generating countries we find that nuclear energy tends to reduce co2 emission for all countries it is also found that income has a beneficial effect on the environment only in some countries finally we find that co2 emissions and income are indeed determined simultaneously while nuclear energy acts exogenously indicating that nuclear energy is the driving variable which significantly influences the long run movements of co2 emissions and income but is not affected by co2 emissions and income in the model

environmental kuznets curve for carbon emissions in pakistan an empirical investigation this study investigates the relationship between carbon emissions income energy consumption and foreign trade in pakistan for the period 1972 2008 by employing the johansen method of cointegration the study finds that there is a quadratic long run relationship between carbon emissions and income confirming the existence of environmental kuznets curve for pakistan moreover both energy consumption and foreign trade are found to have positive effects on emissions the short run results have however denied the existence of the environmental kuznets curve the short run results are unique to the existing literature in the sense that none of the long run determinants of emissions is significant the contradictory results of short and long run give policy makers the opportunity to formulate different types of growth policies for the two terms taking environmental issues into consideration in addition the uni directional causality from growth to energy consumption suggests that the policy makers should not only focus on forecasting future demand for energy with different growth scenarios but also on obtaining the least cost energy furthermore the absence of causality from emissions to growth suggests that pakistan can curb its carbon emissions without disturbing its economic growth

the effect of domestic uncertainty on the real options value of international investments scholars have noted that international investments have the potential to provide firms with real options value under uncertainty to assess this issue prior studies have tended to focus primarily on exchange rate volatility although multinational firms face other types of uncertainty as well including those stemming from their domestic operating environment the role of such uncertainty for firms flexibility needs has not been previously considered in this study we compare the influence of both domestic economic uncertainty and exchange rate uncertainty on the real option value of international investments of korean firms over 16 years of varying uncertainty we find evidence that an international investment network characterized by greater breadth and lower depth is associated with higher firm value under domestic economic uncertainty exchange rate uncertainty however was not found to play a role in firms need for flexibility the results suggest that firms are able to hedge exchange rate uncertainty by using mechanisms such as forward contracts or derivatives thus potentially reducing the impact of this type of uncertainty on their operations

explaining the relationship between co2 emissions and national income the role of energy consumption i estimate a simultaneous equation system in which gdp and co2 emissions are jointly determined i find that including energy consumption in the regression implies a negative relationship between income and co2 emissions which is contrary to previous findings

the role of renewable energy to validate dynamic interaction between co2 emissions and gdp toward sustainable development in malaysia abstract closing the gap between economy activity and environmental quality is one of the solutions for reaching sustainable development in malaysia to do so the cubic polynomial functional form of ekc is utilized by accommodating renewable energy into the base of the ekc model and validating its hypothesis between co 2 emissions and gdp growth for the 1971 2015 period the f bounds vecm granger causality cusum and cusumsq tests are utilized the estimated results consistently show that the inverted n shaped ekc hypothesis holds in malaysia ceteris paribus the co 2 emissions will be declined when the gdp reach rm2841 9 billion in 2030 which is beyond the sample period the renewable energy has a negative significant effect on co 2 emissions and the direction of causality is running from co 2 emissions to renewable energy also the gdp growth will be the remedy for environmental pollution problems and that renewable energy is one of important elements to be considered for improving environmental quality a tighter and concentrated environmental policy is needed to direct the environment economic growth nexus toward a downward trend consequently these results may help malaysian policymakers to establish an energy policy that guarantees a balance between economic growth and environmental prosperity

carbon dioxide income and energy evidence from a non linear model abstract this study applies the panel smooth transition regression pstr model to explore the impacts of real income energy and investment on the co 2 income nexus for 99 countries covering the period from 1971 to 2010 we find that in the full sample as real income rises co 2 emissions rapidly increase first and then their increasing rate starts to slow down while the environmental kuznets curve ekc hypothesis for co 2 emissions is supported from the composite results of three income groups our results show that decreasing energy usage improving energy efficiency and enhancing clean energy usage could effectively ease the impacts of real income on co 2 emissions moreover countries with different energy trade conditions and income levels have different co 2 income correlations indicating that one size does not fit all

carbon intensity and economic development 1962 1991 a brief exploration of the environmental kuznets curve the relationship between national carbon dioxide emissions intensity co2 emitted per unit of gross domestic product and level of economic development has changed from essentially linear in 1962 to strongly curvilinear in 1991 the inverted u curve reached statistical significance briefly in the early 1970s and increasingly since 1982 this is the result not of groups of countries passing through stages of development but of efficiency improvements in a small number of wealthy countries combined with worse performance in poor and middle income countries the curvilinear relation is deepening and is likely to persist due to constraints on poorer countries in the world economy

multimarket contact and collusive behavior traditional analyses of industrial behavior typically link the exercise of market power in an industry to internalfeatures such as demand conditions concentration and barriers to entry nevertheless some economists have remained concerned that external factors such as contact across markets may also play a significant role in determining the level of competitiveness in any particular industry in this article we examine the effect of multimarket contact on the degree of cooperation that firms can sustain in settings of repeated competition we isolate conditions under which multimarket contact facilitates collusion and show that these collusive gains are achieved through modes of behavior that have been identified in previous empirical studies of multimarketfirms

economic models for the environmental kuznets curve a survey abstract the environmental kuznets curve ekc refers to an inverted u shaped relationship between some pollutant level and per capita income i e the environmental quality deteriorates at early stages of economic growth and subsequently improves at a later stage since the early 1990s a considerable number of empirical studies have been conducted on the ekc and although there is no conclusive proof it has been recognized that the ekc emerges as an empirical regularity however some recent studies cast doubt on the concept and methodology of empirical results and evidence of the existence of the ekc has been questioned in fact how economic growth affects the environmental quality i e the shape of the ekc is still controversial in order to identify the actual relationship between the environmental quality and economic growth it is essential to develop economic models from various points of view this paper overviews the current stage of theoretical models that explain such relationship

endogenous verifiability and relational contracting for contracting parties it will often be uncertain whether a legal court is able to enforce the real intents of their contract the strict requirements of verifiability make it costly if not impos sible for parties to arrange their transactions and design their contract in a way that makes it completely protected by the court a way out is then to rely on self enforcing relational con tracts through repeated transactions the parties can make it costly for each other to breach the contract by letting breach ruin future trade but the self enforcing range of contracts is limited so the court s ability to enforce a contract is not without consequence for the contracting parties if possible the parties may thus have incentives to take costly actions that affect the ability of the court both ex ante preparations in terms of detailed contracting and ex post revelation of informa tion can increase the probability of fair court enforcement in this paper we focus on the former assuming that the parties are able to improve the verifiability of the contracted actions by care ful ex ante contract specifications we assume that careful contracting can improve the court s ability to verify whether an action conforms to the one described in the contract then we ask what happens to the self enforcing contract equilibrium if a party takes actions ex ante that affect the probability of verification in order to provide some answers we analyze a simple repeated principal agent game where the verifiability of the agent s actions is endogenously determined by the principal s investments in drafting an explicit contract pertaining to the quality of the agent s output the model makes it possible to identify some subtle effects of two key enforcement devices legal courts and repeated interaction note that by endogenizing verifiability we also endog enize the degree of contractual incompleteness and the equilibrium level of incompleteness will depend on the verification technology i e the resource costs that are necessary to achieve various verifiability levels this verification technology will be influenced in an essential way by the quality of courts in fact we can use the model to study relationships between two distinct aspects of courts namely their ability which influences the verification technology and their predictability which manifests itself in the equilibrium level of verifiability i e the probability with which the court in fact will verify the relevant action the repeated game approach formalizes an economic concept of trust and trustworthiness since a party honors trust if the present value of honoring exceeds the present value of abusing it the discount factor is then a proxy for the trust level in the relationship by studying the effect of variations in verification technology and the discount factor we can gain insight into the rela tionship between court ability explicit contracting trust and relational contracting below we summarize the results

endogenous institutional selection building trust and economic growth abstract private order market institutions founded on trust based relational contracts suffer adverse selection and moral hazard problems while public order market institutions have a limited capacity to enforce contracts i model agent selection between contract enforcement institutions and demonstrate that the state s contract enforcement capacity is complementary to private order contract enforcement institutions for low to moderate levels of public order enforcement capacity this suggests that initial improvements to public order institutions cause the accumulation of trust and result in economic growth in both institutions however i show that the private order institution must collapse once the public order contract enforcement capacity is too great

empirical study on the environmental kuznets curve for co2 in france the role of nuclear energy this paper attempts to estimate the environmental kuznets curve ekc in the case of france by taking the role of nuclear energy in electricity production into account we adopt the autoregressive distributed lag ardl approach to cointegration as the estimation method additionally we examine the stability of the estimated models and investigate the granger causality relationships between the variables in the system the results from our estimation provide evidence supporting the ekc hypothesis and the estimated models are shown to be stable over the sample period the uni direction running from other variables to co2 emissions are confirmed from the casualty tests specifically the uni directional causality relationship running from nuclear energy to co2 emissions statistically provides evidence on the important role of nuclear energy in reducing co2 emissions

modeling the evolutionary nexus between carbon dioxide emissions and economic growth abstract given the fast paced world economy increasing carbon dioxide co2 emissions have caused serious concern regarding global warming many studies have examined the nexus between co2 emissions and economic growth and inconsistent results are provided limited evidence suggests that different time periods under investigation could be a source of inconsistency but there lacks of a thorough analysis this paper systematically focuses on the evolutionary characteristics of the nexus to explore the influence of time periods the panel data are reorganized by considering different time periods in various countries and an intelligent data driven approach symbolic regression is applied to discover models for each period without predefined structure and parameters three issues does the time period matter what are the trends in different time periods what are the applicable scopes of the models have been addressed in this paper the results reveal the evolutionary nature of the nexus and it is verified that an intrinsic time period distinction does generate extrinsic inconsistency the detailed dynamics of models indicate that the optimal models tend to be more complex as the time periods are extended for countries with different locations and income levels the applicable scopes of the four superior models monotonically increasing inverted u shaped inverted n shaped and m shaped vary in different time periods the findings highlight that the effect of time periods cannot be ignored and the models should not be applied unconditionally when conducting empirical research finally several policy implications are provided which are critical for the balance of economic growth and co2 emissions particularly in some developing countries

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

impact of corruption in public sector on environmental quality implications for sustainability in brics and next 11 countries abstract this study investigates the impact of corruption in public sector on carbon emissions in presence of energy use segregation following the environmental kuznets curve ekc framework the study has been carried out for brazil russia india china south africa brics and next 11 countries over the period of 1990 2017 along with the finding of inverted n shaped ekc for both the cases we find that incidents of corruption enhance environmental degradation by reducing the positive impact of renewable energy consumption on environmental quality and increasing the negative impact of fossil fuel consumption this study has also divulged that the corruptive practices are more prone in case of the countries where the development is mature and institutionalization is more stringent based on these findings we suggest that environmental policies should take account of the corruption and thereby making the policies more robust and effective

environment kuznets curve for co2 emissions a cointegration analysis for china abstract this study examines the long run relationship between carbon emissions and energy consumption income and foreign trade in the case of china by employing time series data of 1975 2005 in particular the study aims at testing whether environmental kuznets curve ekc relationship between co 2 emissions and per capita real gdp holds in the long run or not auto regressive distributed lag ardl methodology is employed for empirical analysis a quadratic relationship between income and co 2 emission has been found for the sample period supporting ekc relationship the results of granger causality tests indicate one way causality runs through economic growth to co 2 emissions the results of this study also indicate that the carbon emissions are mainly determined by income and energy consumption in the long run trade has a positive but statistically insignificant impact on co 2 emissions

the co2 emissions development nexus revisited abstract this study revisited the co2 emissions development nexus for this purpose a comprehensive analysis was performed using recent and extensive datasets and employing three different econometric methods namely the cross sectional regression the cointegrating regression and the threshold regression the findings revealed that an environmental regime transformation had occurred in the relationship between the co2 emission intensity and economic development thus the results indicated that in recent decades the inverted n shaped cubic relationship between these variables transformed into the inverted u shaped quadratic relationship by contrast as far as the relationship between the co2 emission per capita and economic development is concerned the u shaped relationship between the variables remained unchanged in other words the present study has detected the inverted u shaped or the environmental kuznets curve ekc relationship between the co2 emission intensity and economic development however it was unable to validate the ekc relationship between the co2 emission per capita and economic development

cluster analysis of the relationship between carbon dioxide emissions and economic growth abstract as global warming continues to worsen the balance between carbon dioxide emissions and economic growth has received increasing attention and carbon reduction comes to be an urgent task in many countries in literature various regression models have been developed to investigate the relationship between carbon dioxide emissions and economic growth such as the inverted u shaped ekc model inverted n shaped model etc which play critical roles in analyzing the relationships existing studies suggest that some countries follow similar models to describe the relationships while others employ different ones regarding the interplay between carbon dioxide emissions and economic growth there lacks a cluster analysis to systematically uncover the similarity of countries that employ models more similar to each other than to the countries in other clusters in this paper a novel clustering approach is proposed to identify clusters of 67 countries from the spatial temporal and descriptive dimensions unlike the traditional clustering technique in which clusters are determined by geometric distances the clusters in this research are obtained based on the differences between the fitting models of the countries in each cluster the first step of the approach is to find clusters of countries sharing similar models in a given year based on the symbolic regression method and the second step is to determine the countries that frequently cooccur in the same cluster by the apriori algorithm the results present two high order clusters with different dynamic features during the period between 1971 and 2010 one high order cluster mainly consists of countries in higher level of income while the other contains lower income level countries and the carbon intensities of the two high order clusters have distinct differences the findings suggest that the countries within the same cluster could learn more lessons from each other while countries belonging to different clusters should not be examined together indiscriminately several policy implications are provided which may inform decision making for policymakers when choosing proper learning objects and help researchers with designing optimal models for specific countries

environmental degradation in france the effects of fdi financial development and energy innovations abstract this paper explores the determinants of carbon emissions in france by accounting for the significant role played by foreign direct investment fdi financial development economic growth energy consumption and energy research innovations in influencing co 2 emissions function in this endeavour we employ the novel sor shahbaz et al 2017 unit root test on french time series data over the period 1955 2016 to examine the order of integration in the presence of sharp and smooth structural breaks in the variables we also apply the bootstrapping bounds testing approach recently developed by mcnown et al 2018 to investigate the presence of cointegration and the empirical findings underscore the presence of cointegration among the time series moreover we find that fdi has a positive impact while energy research innovations have a negative impact on french carbon emissions financial development lowers carbon emissions thereby improving the french environmental quality fdi degrades the environment and thus supports the pollution haven hypothesis in france similarly financial development suggests that financial stability is a required condition for improving environmental quality so are energy research innovations contrarily energy consumption is positively linked with carbon emissions however the relationship between economic growth and co 2 emissions is an inverted u which is a validation of the environmental kuznets curve ekc

literature survey on the relationships between energy environment and economic growth abstract the aim of this study is to exhibit an exhaustive survey which is related to the great flight of the literature of energy environment growth nexus at the individual and regional scale studies covering the period from 1978 to 2014 the survey takes into consideration the sample country region etc periods covering econometric strategies and conclusions our survey is based on the causality direction among i the energy use variables electricity nuclear renewable and non renewable and output growth ii between economic growth and environment and between the three variables at the same time globally these surveys provide paradoxical and not conclusive results which energy consumption can boost economic growth through the productivity enhancement and it can boost also the environmental damages through the enhancement of pollutant emissions our survey sheds more the lights on the energy environment growth literature by giving an extensive listing 1978 2014 of these causal linkages among the energy use variables environment and economic growth for both individual and collective cases there is a unanimous consensus about the importance of dealing with such dynamic relationship which is seems to be a cornerstone element in setting any ambition strategies energy ecological and economics

co2 emissions energy consumption economic and population growth in malaysia abstract this study investigates the dynamic impacts of gdp growth energy consumption and population growth on co2 emissions using econometric approaches for malaysia empirical results from ardl bounds testing approach show that over the period of 1970 1980 per capita co2 emissions decreased with increasing per capita gdp economic growth however from 1980 to 2009 per capita co2 emissions increased sharply with a further increase of per capita gdp this is also supported by the dynamic ordinary least squared dols and the sasabuchi lind mehlum u slm u test tests consequently the hypothesis of the ekc is not valid in malaysia during the study period the results also demonstrate that both per capita energy consumption and per capita gdp has a long term positive impacts with per capita carbon emissions but population growth rate has no significant impacts on per capita co2 emission however the study suggests that in the long run economic growth may have an adverse effect on the co2 emissions in malaysia thus significant transformation of low carbon technologies such as renewable energy and energy efficiency could contribute to reduce the emissions and sustain the long run economic growth

do countries influence neighbouring pollution a spatial analysis of the ekc for co2 emissions abstract by considering spatial relationships this study aims to analyse to what extent per capita co2 emissions are determined by renewable energy consumption the share of the services sector in gdp energy intensity and real per capita income a panel data set composed of 173 countries over the 1990 2014 period is used to estimate an environmental kuznets curve ekc augmented by neighbouring per capita income and energy intensity both standard and spatial forms are estimated for seven different sets of countries to assess the robustness of the results finally several forecasts are performed to verify global sustainability and to provide some policy suggestions for the period 2015 2100 the empirical results indicate that i most areas support the standard ekc ii there seems to be an inverted u shaped relationship between neighbouring per capita income and national per capita emissions in europe asia and the world as a whole iii neighbouring energy intensity increases national per capita emissions and iv forecasts show that economic growth will accelerate climate change however a steady annual growth in renewable energy consumption and a steady decrease in energy intensity both close to 2 5 may guarantee environmental sustainability prior to 2100

investing in a relationship a principal can make an investment anticipating a repeated relationship with an agent but the agent may appropriate the returns through ex post bargaining i study how this holdup problem and efficiency depend on the contracting environment when investment returns are observable informal contracts ex post can be more efficient than formal contracts as they induce higher investment ex ante the principal invests not only to generate direct returns but also to improve relational incentives unobservability of returns increases the principal s ability to appropriate the returns but reduces her ability to improve incentives the optimal information structure depends on bargaining power

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

incomplete contracts and signaling this article presents a principal agent model in which asymmetric information leads to contractual incompleteness i show that in the presence of transactions costs incompleteness may act as a signal of the principal s type two types of transactions costs are considered those incurred ex ante drafting costs and those incurred ex post enforcement or verification costs i prove that in the presence of either of these costs asymmetric information leads to more contractual incompleteness than full information does

participation and duration of environmental agreements we analyze participation in international environmental agreements in a dynamic game in which countries pollute and invest in green technologies if complete contracts are feasible participants eliminate the holdup problem associated with their investments however most countries prefer to free ride rather than participate if investments are noncontractible countries face a holdup problem every time they negotiate but the free rider problem can be mitigated and significant participation is feasible participation becomes attractive because only large coalitions commit to long term agreements that circumvent the holdup problem under well specified conditions even the first best outcome is possible when the contract is incomplete

regional differences in the dynamic linkage between co2 emissions sectoral output and economic growth environmental degradation measured by co2 emissions is a significant challenge to sustainable economic development owing to significant differences in the empirical relationship between the economic growth and co2 emissions and policies adopted by different countries to overcome the challenge are not decisive this study aims to generalize our knowledge about the relationship between co2 emissions per capita and economic growth across the world for 1980 2009 periods besides it explores whether the transformation of different economies e g agrarian to industrial and industrial to sophisticated service economy over the past few decades yielded any significant positive impact towards sustainable economic development by reducing the level of co2 emission empirical results suggest that i except for high income countries environmental kuznets curve ekc is a general phenomenon across the world and ii the transformation of different economies towards a service economy has produced more pollution in high income countries and less pollution in low and middle income countries

the importance of renewable energy consumption and fdi inflows in reducing environmental degradation bootstrap ardl bound test in selected 9 countries abstract this study examines the relationship between renewable energy consumption non renewable energy consumption foreign direct investment economic growth and carbon emissions for the nine countries i e denmark finland france india italy morocco norway portugal sweden identified in the climate change performance index ccpi 2018 report this study mainly aims to demonstrate the role of renewable energy consumption and foreign direct investment on co2 emissions in countries with high scores in the ccpi using the newly developed bootstrap autoregressive distributed lag ardl approach for this purpose the unit root properties of the variables are determined by sharp and smooth structural break unit root test sor shahbaz et al 2018 we then conduct a bootstrap ardl test developed by mcnown et al 2018 to investigate the existence of cointegration we also use granger causality based on the bootstrap ardl approach to identify causal relationships between variables empirical analysis results show only a few cointegration relationships between variables exist however we have identified significant long term relationships between foreign direct investment renewable energy consumption and economic growth in some countries and our study includes important policy implications particularly for relationship among co2 emissions and foreign direct investment inflows

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

the impact of foreign direct investment on environmental quality a bounds testing and causality analysis for turkey abstract this study aims to investigate the impact of foreign direct investment fdi together with gross domestic product gdp the square of gdp and energy consumption on carbon dioxide co2 emissions in turkey over the period 1974 2010 we employ both the bounds test approach which has superior properties especially in small samples and the hatemi j test which takes structural breaks into consideration in the co integration analysis due to the co integration relationship between co2 emissions and other variables the autoregressive distributed lag ardl model is used in order to investigate short and long run elasticity between the variables the long run coefficients of the ardl model indicate that the effect of fdi on co2 emissions is positive but relatively small while the effects of the gdp and energy consumption on co2 emissions are quite considerable moreover the short run coefficients obtained by the error correction model ecm are found to be similar to those of the long run model the findings support the validity of the environmental kuznets curve ekc hypothesis in both time horizons the vector ecm based granger causality test is also applied to investigate the causal link the causality test results indicate the existence of a causality running from all explanatory variables to co2 emissions in the long run overall the findings suggest that turkey should promote energy efficiency with sustainable growth and encourage more fdi inflows particularly in technology intensive and environment friendly industries to improve environmental quality

nash equilibrium and welfare optimality if is a set of social alternatives a social choice rule scr assigns a subset of a to each potential profile of individuals preferences over a where the subset is interpreted as the set of welfare optima a game form or mechanism implements the social choice rule if for any potential profile of preferences 1 any welfare optimum can arise as a nash equilibrium of the game form implying in particular that a nash equilibrium exists and 2 all nash equilibria are welfare optimal the main result of this paper establishes that any scr that satisfies two properties monotonicity and no veto power can be implemented by a game form if there are three or more individuals the proof is constructive

foreign direct investment income and environmental pollution in developing countries panel data analysis of latin america abstract effects of foreign direct investment fdi and income on pollution emissions are examined using time series data from 1980 to 2010 for 14 latin american countries specifically we test the validity of pollution haven hypothesis phh and environmental kuznets curve ekc hypothesis for this region results from panel fixed and random effects models that controlled the effects of physical capital energy human capital population density and unemployment rate indicate the validity of both the phh and ekc hypothesis estimating two separate models for high and low income countries does not alter the findings for the phh however the impacts of human capital on pollution emission are found to be different for the two groups of countries policies that focus on attracting clean and energy efficient industries through fdi have potential to improve environmental health while enhancing economic growth in latin america

optimal incentives for teams much of the existing theory of incentives describes a static relationship that lasts for just one transaction this static assumption is not only unrealistic but the resulting predictions appear to be at odds with many work organizations the current paper introduces possible long term interaction among agents and studies how the design of explicit incentives and work organizations can exploit and interact with the implicit incentives generated by the repeated interaction of the agents the optimal incentive scheme is shown to display observed features of the increasingly popular teams such as the use of low powered group incentives
