renewable energy consumption urbanization financial development income and co2 emissions in turkey testing ekc hypothesis with structural breaks abstract in this study the short and long run dynamic relationship between per capita gdp per capita carbon dioxide co2 emissions financial development per capita total renewable energy consumption hydropower consumption alternative energy consumption and urbanization was investigated by using ardl bounds testing approach gregory hansen and hatemi j cointegration tests for turkey during 1974 2014 the results of three cointegration test indicated that there was a long run relationship between these variables the coefficients obtained from the ardl fully modified least squares fmols and canonical cointegrating regression ccr estimators showed that economic growth financial development and urbanization increase environmental degradation while total renewable energy consumption hydropower consumption and alternative energy consumption had no effect on co2 emissions the findings showed that economic growth caused the greatest increases in co2 emissions followed by urbanization and financial development however renewable energy consumption was not at a desirable level to reduce co2 emissions the study also support environmental kuznets curve ekc hypothesis which establishes an inverted u shaped relationship between economic growth and co2 emissions the turning points of per capita gdp obtained from long run regressions were found to be around 13523 14077 us dollars outside the sample period the overall results indicated that turkey has not reached the level of per capita gdp that can reduce environmental pollution and renewable energy consumption is not a solution to reduce co2 emissions

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

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

income inequality and co2 emissions in the g7 1870 2014 evidence from non parametric modelling abstract we examine whether income inequality effected carbon emissions in what are now the world s wealthiest countries over the period 1870 2014 employing a non parametric panel estimation method with cross sectional and time varying coefficients we find that the relationship between income inequality and co2 emissions is highly non linear in terms of signs and significance the nonparametric coefficient function for income inequality is found to vary over the period 1870 2014 income inequality exhibits a significant positive effect from 1870 to 1880 and a significant negative impact from 1950 to 2000 on co2 emissions we also find that for extended periods between 1881 and 1949 and between 2000 and 2014 there is no significant relationship between the two variables

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

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

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

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

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

developments in the throughput income relationship theoretical and empirical observations abstract it has been suggested that the relationship between income and the associated environmental pressure in terms of derived materials inputs and pollution levels may take an inverted u shape indicating a delinking of environmental pressure from economic growth in relation to rising per capita incomes the likelihood of such a relationship being persistent is discussed in the context of a simple macro model of industrial metabolism and the possibility of relinking clearly emerges data on specific indicators of environmental pressure i e the throughput of materials energy and the volume of transport in 19 countries have been used to investigate patterns of delinking the results suggest that delinking may not be persistent already some advanced economies may be entering a new period of relinking the relationships between environmental pressure and welfare in the medium long term may be n shaped rather than inverted u shaped

an alternative analysis of apparent ekc type transitions abstract the hypothesis of the environmental kuznets curve ekc depends upon the assumption that countries pass through a similar environmental impact trajectory as they experience income growth implying that income levels determine pollution levels the authors present evidence that this is not representative of the way many individual country s pollution emission trajectories evolve and question the emphasis on income determinism by the ekc the study proposes that nonlinear dynamic systems analysis provides a more complete description of individual country pollution trajectories in the case of co 2 emissions the nonlinear time trajectories show abrupt transitions that occur contemporaneously with historical events and over a broad range of incomes

on the relationships between co2 emissions energy consumption and income the importance of time variation abstract the environment that governs the relationships between energy consumption carbon dioxide co2 emissions and gross domestic product gdp in the g7 countries changes over time due to variations in economic growth regulatory policy and technology using a novel approach that may detect causalities when the time constant hypothesis is rejected we find significant time varying granger causalities among the variables under consideration there is bidirectional causality between gdp and energy consumption for japan unidirectional causality running from gdp to energy consumption for italy and unidirectional causality running from energy consumption to gdp for the resource country canada moreover the results also show a bidirectional time varying causality between energy consumption and co2 emissions for the united states and causality from energy consumption to co2 emissions for france finally while we find significant time varying causalities running from gdp to co2 emissions for italy and japan the finding of inverted n shaped curves italy and japan lends no support to the traditional environmental kuznets curve ekc hypothesis for these countries it implies that environmental policy and economic growth should go hand in hand other policy implications of the empirical results have been proposed

do economic financial and institutional developments matter for environmental degradation evidence from transitional economies abstract several studies have examined the relationship between environmental degradation and economic growth however most of them did not take into account financial developments and institutional quality moreover stern stern d 2004 the rise and fall of the environmental kuznets curve world development 32 8 1419 1439 noted that there are important econometric weaknesses in the earlier studies such as endogeneity heteroscedasticity omitted variables etc the purpose of this paper is to fill this gap in the literature by investigating the linkage between not only economic development and environmental quality but also financial development and institutional quality we employ the standard reduced form modelling approach to control for country specific unobserved heterogeneity and gmm estimation to control for endogeneity our study considers 24 transition economies and panel data for 1993 2004 our results support the ekc hypothesis while confirming the importance of both institutional quality and financial development for environmental performance we also found that financial liberalization may be harmful for environmental quality if it is not accomplished in a strong institutional framework

co2 emissions energy consumption and economic growth in turkey abstract this paper examines the long run and causal relationship issues between economic growth carbon emissions energy consumption and employment ratio in turkey by using autoregressive distributed lag bounds testing approach of cointegration empirical results for turkey over the period 1968 2005 suggest an evidence of a long run relationship between the variables at 5 significance level in turkey the estimated income elasticity of carbon emissions per capita is 0 606 and the income elasticity of energy consumption per capita is 1 375 results for the existence and direction of granger causality show that neither carbon emissions per capita nor energy consumption per capita cause real gdp per capita but employment ratio causes real gdp per capita in the short run in addition ekc hypothesis at causal framework by using a linear logarithmic model is not valid in turkish case the overall results indicates that energy conservation policies such as rationing energy consumption and controlling carbon dioxide emissions are likely to have no adverse effect on the real output growth of turkey

the environmental kuznets curve for pm2 5 pollution in beijing tianjin hebei region of china a spatial panel data approach abstract the purpose of this study is to exam the existence of environmental kuznets curve ekc of pm2 5 pollution in the beijing tianjin hebei bth region of china as one of the most important economic growth poles in china bth region has long been suffering from air pollution especially pm2 5 pollution thus in this study we utilized satellite observations of pm2 5 pollution and panel data of 13 cities in bth region from 1998 to 2016 to investigate the relationship between economic growth and pm2 5 pollution after verifying the spatial effect of pm2 5 pollution by spatial statistical analysis the spatial econometric model spatial durbin model sdm was chosen over the non spatial model in the examination of ekc the results showed that 1 the relationship between economic growth and pm2 5 pollution presented a significant inverted u shaped pattern though bth region is still in the upward section there is a hope that it will cross the point and enter the downward section in the future 2 the turning points of ekc would happen later with spatial effect considered compared to the result of non spatial model 3 the turning point of ekc would not happen until the region enter the post industrial economy stage moreover though some of the cities in bth region have entered post industrial stage none of them has cross the turning point of ekc results of this study indicate a promising future in the control of pm2 5 pollution as well as provide suggestions to put more emphasis on regional cooperative governance in air pollution control for the policy makers

the impact of growth energy and financial development on the environment in china a cointegration analysis this article aims to investigate the impact of financial development economic growth and energy consumption on environmental pollution in china from 1953 to 2006 using the autoregressive distributed lag ardl bounds testing procedure the main objective is to examine the long run equilibrium relationship between financial development and environmental pollution the results of the analysis reveal a negative sign for the coefficient of financial development suggesting that financial development in china has not taken place at the expense of environmental pollution on the contrary it is found that financial development has led to a decrease in environmental pollution it is concluded that carbon emissions are mainly determined by income energy consumption and trade openness in the long run moreover the findings confirm the existence of an environmental kuznets curve in the case of china

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

carbon dioxide emission and income a temporal analysis of cross country distributional patterns the existence of a cointegrating relationship between income and co2 emission for individual country groups suggests existence of a corresponding relationship between the inter country disparities in the levels of income and co2 emission this paper explores the relationship between the patterns of cross country distribution of income and co2 emission and temporal shifts in such a relationship this paper also examines how the mean level of per capita co2 emission and its distributional inequality are related to the corresponding mean income level and the distributional inequality of income the analysis is based on a cross country panel data set at the level of country group environmental quality demanded is treated as a private good and not as a public good as done in most other studies the technique of lorenz and specific concentration curve analysis are used as the basic analytical framework to argue that a measure of relative distributional inequality of income should be used as an explanatory variable in the environmental kuznets curve ekc relationship along with the mean income level in the empirical exercise johansen s cointegration analysis technique is used to explore existence of statistically significant cointegrating vector s relating mean level of emission and specific concentration ratio scr of emission to mean income level and lorenz ratio lr of income the empirical results confirm that the pattern of cross country income distribution has significant effect on the mean level of emission for all the country groups considered

economic growth energy consumption financial development international trade and co2 emissions in indonesia this study examines the linkages among economic growth energy consumption financial development trade openness and co2 emissions over the period of 1975q1 2011q4 in the case of indonesia the stationary analysis is performed by using zivot andrews structural break unit root test and the ardl bounds testing approach for a long run relationship between the series in the presence of structural breaks the causal relation between the concerned variable is examined by the vecm granger causality technique and robustness of causal analysis is tested by innovative accounting approach iaa our results confirm that the variables are cointegrated it means that the long run relationship exists in the presence of structural break stemming in the series the empirical findings indicate that economic growth and energy consumption increases co2 emissions while financial development and trade openness compact it the vecm causality analysis has shown the feedback hypothesis between energy consumption and co2 emissions economic growth and co2 emissions are also interrelated i e bidirectional causality financial development granger causes co2 emissions the study opens up a new policy insights to control the environment from degradation by using energy efficient technologies financial development and trade openness can also play their role in improving the environmental quality

disclosure of environmental violations and the stock market in the republic of korea for almost 20 years the ministry of environment of the republic of korea has published on a monthly basis a list of enterprises that fail to comply with national environmental laws and regulations in this paper the authors examine the reaction of investors to the publication of these lists and show that enterprises appearing on these lists have experienced a significant decline in their market valuation firms in developing countries are often said to have no incentives to invest in pollution control because they typically face weak monitoring and enforcement of environmental regulations the findings of the authors however indicate that the inability of formal institutions to control pollution through fines and penalties may not be as serious an impediment to pollution control as is generally argued environmental regulators in developing countries could harness market forces by introducing structured programs to release firm specific information about environmental performance

economic growth trade and energy implications for the environmental kuznets curve abstract the environmental kuznets curve ekc hypothesis asserts that pollution follows an inverted u path with respect to economic growth the ekc has been explained in terms of structural changes in the composition of economic output and increased environmental regulation at higher income levels while some authors have incorporated the impact of trade policy orientation on the ekc the impact of the actual movement between countries of goods that embody pollution has not been considered this paper attempts to econometrically quantify the effect using pooled cross country and time series data the ekc hypothesis is examined with respect to commercial energy consumption the source of many serious environmental problems it was found that while both industrializing and industrialized countries have added to their energy requirements by exporting manufactured goods the growth has been substantially higher in the former at the same time industrialized countries have been able to reduce their energy requirements by importing manufactured goods exports of manufactured goods by industrialized countries has thus been an important factor in generating the upward sloping portion of the ekc and imports by industrialized countries have contributed to the downward slope

environmental kuznets curve and financial development in pakistan abstract in this study we analyzed the effects of financial development per capita real income the square of per capita real income per capita energy consumption and openness on per capita co 2 emissions for pakistan during 1972 2013 the bound f test for cointegration yielded evidence of a long term relationship among these variables the results confirm the existence of an environmental kuznets curve in pakistan for both the short and long term this finding indicates that at the initial stage of development the level of co 2 increases with income and after some threshold level of income this relationship may change from positive to negative as more efficient infrastructure and energy efficient technology are implemented during the development process of the country the findings of this study also reveal a significantly positive sign for the coefficient of financial development suggesting that financial development has occurred at the expense of environmental quality the results further indicate that the key contributing factors to carbon emissions in pakistan are income energy consumption and financial development in addition the openness variable has no significant influence on carbon emission in either the short or long term

is monthly us natural gas consumption stationary new evidence from a garch unit root test with structural breaks we apply a recently developed unit root test that simultaneously accounts for heteroskedasticity and structural breaks to united states monthly natural gas consumption we find that united states monthly natural gas consumption is stationary our results illustrate the importance of accounting for heteroskedasticity when testing for a unit root in energy consumption with higher frequency data

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

the impact of financial development on energy consumption in emerging economies abstract financial development is often cited as a very important driver of economic growth in emerging economies and it is thus likely that financial development affects energy demand this study uses generalized method of moments estimation techniques to examine the impact of financial development on energy consumption in a sample of emerging countries several different measures of financial development are examined using a panel data set on 22 emerging countries covering the period 1990 2006 the empirical results show a positive and statistically significant relationship between financial development and energy consumption when financial development is measured using stock market variables like stock market capitalization to gdp stock market value traded to gdp and stock market turnover the implications of these results for energy policy are discussed

does higher economic and financial development lead to environmental degradation evidence from bric countries abstract a vast number of studies addressed the environmental degradation and economic development but not financial development moreover as argued by stern 2004 the rise and fall of the environmental kuznets curve world development 32 1419 1439 they present important econometric weaknesses using standard reduced form modeling approach and controlling for country specific unobserved heterogeneity we investigate the linkage between not only economic development and environmental quality but also the financial development panel data over period 1992 2004 is used we find that both economic and financial development are determinants of the environmental quality in bric economies we show that higher degree of economic and financial development decreases the environmental degradation our analysis suggests that financial liberalization and openness are essential factors for the co 2 reduction the adoption of policies directed to financial openness and liberalization to attract higher levels of r d related foreign direct investment might reduce the environmental degradation in countries under consideration in addition the robustness check trough the inclusion of us and japan does not alter our main findings

the long run and causal analysis of energy growth openness and financial development on carbon emissions in turkey abstract the aim of this paper is to examine the causal relationship between financial development trade economic growth energy consumption and carbon emissions in turkey for the 1960 2007 period the bounds f test for cointegration test yields evidence of a long run relationship between per capita carbon emissions per capita energy consumption per capita real income the square of per capita real income openness and financial development the results show that an increase in foreign trade to gdp ratio results an increase in per capita carbon emissions and financial development variable has no significant effect on per capita carbon emissions in the long run these results also support the validity of ekc hypothesis in the turkish economy it means that the level of co 2 emissions initially increases with income until it reaches its stabilization point then it declines in turkey in addition the paper explores causal relationship between the variables by using error correction based granger causality models

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

the effects of financial development economic growth coal consumption and trade openness on co2 emissions in south africa abstract this paper explores the effects of financial development economic growth coal consumption and trade openness on environmental performance using time series data over the period 1965 2008 in case of south africa the ardl bounds testing approach to cointegration has been used to test the long run relationship among the variables while short run dynamics have been investigated by applying error correction method ecm the unit root properties of the variables are examined by applying saikkonen and lutkepohl 2002 econometric theory 18 313 348 structural break unit root test our findings confirmed long run relationship among the variables results showed that a rise in economic growth increases energy emissions while financial development reduces it coal consumption has significant contribution to deteriorate environment in south african economy trade openness improves environmental quality by reducing the growth of energy pollutants our empirical results also verified the existence of environmental kuznets curve this paper opens up new insights for south african economy to sustain economic growth by controlling environment from degrdation through efficient use of energy

environmental productivity and kuznets curve in india abstract as a result of india s extremely rapid economic growth the scale and seriousness of environmental problems are no longer in doubt whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies in this study we use state level industry data of sulfur dioxide nitrogen dioxide and suspended particular matter over the period 1991 2003 employing recently developed productivity measurement technique we show that overall environmental productivities decrease over time in india furthermore we analyze the determinants of environmental productivities and find environmental kuznets curve type relationship existences between environmental productivity and income panel analysis results show that the scale effect dominates over the technique effect therefore a combined effect of income on environmental productivity is negative

the world per capita electricity consumption distribution signs of convergence abstract considering residential per capita electricity consumption as one of the most suitable economic welfare indicators the aim of this paper is to explore worldwide differences on this variable over the period 1980 2007 the paper adds to the standard practice of and convergence analysis by tracking the external shape and time evolution of the entire distribution applying nonparametric techniques density functions and stochastic kernels to a sample of 98 countries the main finding is that a weak process of electricity consumption convergence has taken place this reduction of disparities is clearly related to at least three issues firstly the rapid economic changes experienced by some developing countries secondly the energy conservation policies implemented by most developed countries following the first oil shock and thirdly the growing awareness on energy issues in rich countries notwithstanding this the ergodic distribution on per capita electricity consumption indicates that large cross country disparities will persist in the long run

the relative technical efficiency of northern and southern u s farms in 1860 prior to the 1960s it was widely accepted that the slave economy of the south was unprofitable and inefficient 14 however in the 1960s a number of scholars demonstrated using economic analysis and econometric techniques that slavery was indeed profitable 5 12 this evidence was further supported by findings that per capita income in the south was not only high by standards of the mid nineteenth century but was also growing rapidly during the two decades preceding the civil war 7 8 9 although these findings were important they did not address the issue of the technical efficiency of northern and southern farms however in the early 1970s fogel and engerman determined that southern agriculture was more technically efficient than northern agriculture 11 13 this paper will also compare the relative technical efficiency of northern and southern farms for a sample of farms for the year 1860 however the method we will use to measure technical efficiency is superior to that used by fogel and engerman a non parametric production frontier is constructed with inefficiency measured by the extent to which firms operate below the frontier using this approach it is possible to determine whether technical inefficiency is the result of operating off of the isoquant pure technical inefficiency or operating at an inappropriate scale i e not operating at constant returns to scale the next section of this paper reviews the literature concerning the relative technical efficiency of northern relative to southern agriculture section three discusses the methodology used in this paper to measure the technical efficiency of farms section four presents and analyzes the empirical results and section five summarizes the paper

energy consumption economic growth and carbon emissions challenges faced by an eu candidate member abstract this paper investigates the long run granger causality relationship between economic growth carbon dioxide emissions and energy consumption in turkey controlling for gross fixed capital formation and labor the most interesting result is that carbon emissions seem to granger cause energy consumption but the reverse is not true the lack of a long run causal link between income and emissions may be implying that to reduce carbon emissions turkey does not have to forgo economic growth

environmental kuznets curve time series application for turkey why controversial results exist for similar models abstract this paper investigates the environmental kuznets curve ekc hypothesis using 40 year spanned time series for the turkey case co 2 emission series representing environmental pressure and gdp per capita values representing economic development are used for the period 1968 2007 a cointegration has been determined among nonstationary series first phases of an inverted u form ekc relationship have been determined for turkey from the econometric estimations this result is conflicting with that of the similar models for turkey case on the other hand this conflict refers the important arguments in the literature and constitutes the main points of the paper sensitivity critiques for example ahking et al for cointegration tests johansen and engle granger tests have been supported in our study moreover we detected important diversion in results according to drift and trend assumptions both in ci vector and ekc model specifications we conclude that building ekc model according to cointegration ci equation restrictions can be important source for diversion when sensitivity exists in estimations and cointegration tests therefore ekc estimations should be held in non restrictive way the additional structural reasons have been also discussed for developing country ekc cases the most important one is that the narrow income sample of developing countries makes it possible to be defined by similar but different paths therefore policy implications to be drawn from those analyses should not ignore this feature of developing country analyses

will initiatives to promote hydroelectricity consumption be effective evidence from univariate and panel lm unit root tests with structural breaks abstract this paper examines whether initiatives to promote hydroelectricity consumption are likely to be effective by applying univariate and panel lagrange multiplier lm unit root tests to hydroelectricity consumption in 55 countries over the period 1965 2011 we find that for the panel as well as about four fifths of individual countries that hydroelectricity consumption is stationary this result implies that shocks to hydroelectricity consumption in most countries will only result in temporary deviations from the long run growth path an important consequence of this finding is that initiatives designed to have permanent positive effects on hydroelectricity consumption such as large scale dam construction are unlikely to be effective in increasing the share of hydroelectricity relative to consumption of fossil fuels

the impact of financial development on carbon emissions an empirical analysis in china given the complexity between china s financial development and carbon emissions this paper uses some econometric techniques including cointegration theory granger causality test variance decomposition etc to explore the influence of financial development on carbon emissions results indicate that first china s financial development acts as an important driver for carbon emissions increase which should be taken into account when carbon emissions demand is projected second the influence of financial intermediation scale on carbon emissions outweighs that of other financial development indicators but its efficiency s influence appears by far weaker although it may cause the change of carbon emissions statistically third china s stock market scale has relatively larger influence on carbon emissions but the influence of its efficiency is very limited this to some extent reflects the relatively lower liquidity in china s stock markets finally among financial development indicators china s fdi exerts the least influence on the change of carbon emissions due to its relatively smaller volume compared with gdp but it is mainly utilized in carbon intensive sectors now therefore with the increase of china s fdi in the future many efforts should be made to adapt its utilizing directions and play its positive role in promoting low carbon development
