energy market liberalization and renewable energy policies in oecd countries abstract this paper investigates the effect of energy liberalization compared to other drivers on policies that support renewable energy in a long panel of oecd countries we estimate this effect by accounting for the endogeneity of liberalization related to joint decisions within a country s energy strategy using regulation in other industries as instruments we find that energy liberalization increases public support for renewable energy the effect of liberalization is the second largest after the effect of per capita income and is mostly driven by reductions in entry barriers while the effect of privatization is unclear this finding suggests that a reduction in the monopolistic power of state owned utilities has a positive effect on renewable energy policies when various types of actors are ensured access to the grid instead of it being provided to only a few large private firms

institutions and the environmental kuznets curve for deforestation a crosscountry analysis for latin america africa and asia abstract the relationship between deforestation and income across 66 countries of latin america africa and asia is examined institutional characteristics as well as macroeconomic policies of each country are hypothesized to impact deforestation results show strong evidence of an environmental kuznets curve ekc relationship between income and deforestation for all three continents institutional structure and macroeconomic policy significantly affect the tropical deforestation process improvements in political institutions and governance significantly reduce deforestation the factors leading to deforestation differ across regions however and there is no one size fits all global policy recommendation for restraining the tropical deforestation process

political instability corruption and policy formation the case of environmental policy abstract this paper develops a theory of environmental policy formation taking into consideration the degree of corruptibility and political turbulence the predictions that emerge are that the interaction between the two variables is important political instability has a negative effect on the stringency of environmental regulations if the level of corruption is low but a positive effect when the degree of corruption is high corruption reduces the stringency of environmental regulations but the effect disappears as political instability increases the empirical findings are fully consistent with the predictions of the model

how does government ownership affect firm performance a simple model of privatization in transition economies abstract we present a game theoretical model of privatization in transition economies we consider the costs and benefits of government ownership and derive the net effect of government ownership on firm performance model predictions are consistent with empirical evidence in the literature

the enduring power of coase abstractby many measures ronald coase has been among the most influential economists of the past 60 years why is this so we suggest that coase s work has enduring appeal to and insight for social scientists in part because it addresses the biggest and most important social problems how do we solve governance and coordination problems when limited information common resource issues and public good issues produce conflicts among several people at once any scholar who works on issues of corporate or common pool governance pollution allocation of seats on legislative committees regulation of systemic risk in financial markets provision of military forces patent thickets creation of optimal communications networks regulation of decreasing cost industries or compensation of corporate officers can see his or her work stemming from several of coase s original insights just as john nash s work reshaped economic theory almost every field of economics and political science is shaped by coasean insights

chinese villages and townships as industrial corporations ownership governance and market discipline1 public firms in a reforming socialist economy face two problems the old soft budget constraint syndrome and new principal agent problems china s township village government owned enterprises tves outperform state owned enterprises soes in growth rate and productivity three explanations are proposed in the literature 1 tves represent informal or ambiguous private property rights which are most efficient in partial reform 2 the small size and scale of township village governments as industrial corporations allows officials to monitor tves directly and to limit their wherewithal for cross subsidizing 3 strict market disciplines facing tves render indirect market monitoring to mitigate agency problems effectively analyses of jiangyin data show that a while both superior to local soes village and township enterprises share similar productivity and b the scale of township village corporations slightly increases productivity i conclude that local state corporatism should be revised to inc

long run trends in energy related external costs this paper considers how energy related external costs change through time it focuses on one of the key periods in the history of energy after a period of declining coal prices and soaring consumption which fuelled the second industrial revolution the nineteenth century british economy was externalising the social costs of energy production and consumption on a massive scale rising from 25 in the 1820s an estimated 60 70 of the average social costs of coal were externalised in the 1880s imposing damages close to 20 of gdp the eventual decline in air pollution concentration around 1900 occurred fifty years later than was broadly socially optimal this experience highlights the evolution of the demand for and supply of environmental quality in the context of economic growth and the nature of related market and government failures implying the necessity for adaptation rather than encouraging mitigation this experience may offer lessons for climate analysis and policy making

inequality and the environmental kuznets curve abstract is income inequality harmful to the environment the answer to this question has not reached a consensus in the literature this study seeks to provide insight into this question by examining the influence of income inequality on the environmental kuznets curve ekc i e the impact of income inequality on the ekc turning point two potential mechanisms through which inequality may affect the ekc turning point by reducing public demand for environmental protection and by increasing a power of capital owners to prevent such protection using a large sample n 170 174 of countries we find evidence of the ekc for so2 emissions and income inequality has a significant impact on the ekc turning point income inequality increases the ekc turning point suggesting that high inequality can be damaging to the environment the results are robust to potential outliers different data sources of income inequality a different so2 emissions measure changes in model specification different samples and an alternative estimation method we also find that inequality appears to be more important than corruption in determining the ekc turning point

legislative organization and pollution taxation the role of political institutions in shaping public policy has been analyzed in isolation from corruption and legislative organization specifically bicameralism has received minimal attention we analyze pollution taxation when decisions are influenced by several veto players such as legislative chambers our theory predicts that an increase in the number of veto players e g moving from uni to bi cameralism pushes the pollution tax towards the social optimum with the effect being conditional on corruption as such dispersion around the optimal tax is lower under bicameralism empirical tests using data from 86 countries support the theory

democratic institutions versus autocratic regimes the case of environmental policy the literature suggests that democracy positively affects environmental policy stringency using the method of propensity score matching we find that this result appears to be largely driven by the parliamentary democracies as opposed to the presidential congressional proportional or majority systems moreover it appears that presidential congressional systems often set environmental policies not significantly different from autocracies these are novel contributions to the literature

governance and deforestation a meta analysis in economics abstract understanding which aspects of forest governance have the potential to effectively reduce deforestation is central to reversing trends in global deforestation there is a multitude of empirical studies examining this relationship using various measures of governance and study designs coming to diverse conclusions in order to identify the source of variation across studies this article conducts a meta analysis of 32 empirical cross country studies in the field of economics containing 227 estimates of the impact of different governance measures on deforestation using an ordered probit model we find that the choice of the governance measure is the main factor in explaining variations in the outcomes of the studies in particular studies using environmental policy ownership rights presence of environmental ngos and rule of law as measures of governance are more likely to find that better governance reduces deforestation in contrast studies using democracy and rights as a measure of governance are more likely to find that deforestation increases when governance is improved the finding that not all aspects of governance improvements are equally supportive of forest conservation suggests that more nuanced analyses of specific aspects of environmental governance are required to guide evidence based policy making

democracy and development the devil in the details does democracy promote economic development this paper reviews recent attempts to address this question that exploited within country variation it shows that the answer is largely positive but also depends on the details of democratic reforms first the sequence of economic vs political reforms matters countries liberalizing their economy before extending political rights do better second different forms of democratic government lead to different economic policies and this might explain why presidential democracy leads to faster growth than parliamentary democracy third it is important to distinguish between expected and actual political reforms taking expectations of regime change into account helps identify a stronger growth effect of democracy

testing the environmental kuznets curve hypothesis across the u s evidence from panel mean group estimators abstract it is widely believed that greenhouse gases contribute to a warmer climate since global warming is a serious threat and greenhouse gas emissions are one of the main causes of it analyzing the effects of economic development on environment have great importance in this study the validity of the environmental kuznets curve ekc hypothesis is tested for the 50 u s states during the 1960 2010 period using recent panel data estimators that take cross sectional dependence and slope heterogeneity into account accordingly the cross sectional dependence and slope heterogeneity robust estimators augmented mean group amg and common correlated effects mean group estimator ccemg provide mixed results the amg estimator strongly validates the ekc hypothesis asserting that the ekc holds in 30 of the 50 states with turning points for income per capita lie between 1292 and 48597 on the contrary the ccemg estimator provides only weak evidence on the ekc hypothesis and the ekc holds only in 10 states with turning points between 2457 and 14603

confronting the environmental kuznets curve t he environmental kuznets curve posits an inverted u relationship between pollution and economic development kuznets s name was apparently attached to the curve by grossman and krueger 1993 who noted its resemblance to kuznets s inverted u relationship between income inequality and development in the first stage of industrialization pollution in the environmental kuznets curve world grows rapidly because people are more interested in jobs and income than clean air and water communities are too poor to pay for abatement and environmental regulation is correspondingly weak the balance shifts as income rises leading industrial sectors become cleaner people value the environment more highly and regulatory institutions become more effective along the curve pollution levels off in the middle income range and then falls toward pre industrial levels in wealthy societies the environmental kuznets curve model has elicited conflicting reactions from researchers and policymakers applied econometricians have generally accepted the basic tenets of the model and focused on measuring its parameters their regressions typically fitted to cross sectional observations across countries or regions suggest that air and water pollution increase with development until per capita income reaches a range of 5000 to 8000 when income rises beyond that level pollution starts to decline as shown in the conventional ekc line in figure 1 in developing countries some policymakers have interpreted such results as conveying a message about priorities grow first then clean up numerous critics have challenged the conventional environmental kuznets curve both as a representation of what actually happens in the development process and as a policy prescription some pessimistic critics argue that crosssectional evidence for the environmental kuznets curve is nothing more than a

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

the instability of the adjusted and unadjusted environmental kuznets curves abstract we test the stability of the unadjusted and adjusted environmental kuznets curves ekcs our results provide evidence in favour of a theoretically funded adjusted ekc hypothesis in which the impact of per capita gdp on co 2 emissions is evaluated conditionally to the effects of the industry mix and of the energy supply infrastructure in this specification the shape of the gdp co 2 relationship appears quite sensitive to changes in the estimation period in the final part of the paper signs and dynamics of fixed effects of individual countries in different specifications are interpreted as measures of virtuous or vicious of environmental behaviour

voting collective action and liberalisation in latin america the rise and fall of the hillinger paradox chile s economic and political evolution after the 1982 83 financial crisis has been offered as a model for the rest of latin america this paper interprets the 1973 military coup and national recovery during the 1980s and 1990s in terms of the presence and absence respectively of the hillinger 1971 paradox the paradox arises when democratic voting on platforms consisting of several issues leads to majority support for a platform itself consisting of issues none of which is supported by the majority in the early 1970s a particular expression of the hillinger paradox led chile to the verge of a bloody civil war and to a prolonged military dictatorship in the mid 1980s an important policy question that of differentiated industrial protection versus free trade was solved by a stable compromise in favour of the latter this avoided the hillinger paradox and eventually made electoral politics possible again

how ambitious are china and india s emissions intensity targets abstract several developing economies have announced carbon emissions targets for 2020 as part of the negotiating process for a post kyoto climate policy regime china and india s commitments are framed as reductions in the emissions intensity of the economy by 40 45 and 20 25 respectively between 2005 and 2020 how feasible are the proposed reductions in emissions intensity for china and india and how do they compare with the targeted reductions in the us and the eu in this paper we use a stochastic frontier model of energy intensity to decompose energy intensity into the effects of input and output mix climate and a residual technology variable we use the model to produce emissions projections for china and india under a number of scenarios regarding the pace of technological change and changes in the share of non fossil energy we find that china is likely to need to adopt ambitious carbon mitigation policies in order to achieve its stated target and that its targeted reductions in emissions intensity are on par with those implicit in the us and eu targets india s target is less ambitious and might be met with only limited or even no dedicated mitigation policies

oil exploitation and the environmental kuznets curve abstract this study refers to a panel estimation of an environmental kuznets curve ekc for oil to determine the factors most affecting oil exploitation in 38 oil producing countries during 1990 2000 control variables such as oil reserves oil price population political rights and the gini index were used to determine its contribution to the main ekc model the empirical results fully support the existence of an ekc for oil exploitation furthermore the result indicates that the proved oil reserves has a significant and positive role in oil production but oil price and population do not significantly affect crude oil production also increased freedoms and a better income distribution will reduce the rate of oil exploitation thus policies aiming at enhancing democratic society and better income distribution would be more compatible with sustainability

trade transboundary pollution and foreign lobbying in this paper we explore the use of trade policy in addressing transboundary stock pollution problems such as acid rain and water pollution we show that a tariff determined by the current level of accumulated pollution can induce the time path of emissions optimal for the downstream polluted country but if the upstream polluting country can lobby the downstream government to impose lower tariffs distortions brought by corruption and foreign lobbying lead to a rise in the upstream country s social welfare and to a decrease in social welfare in the downstream country thus the usefulness of trade policy as a tool for encouraging cooperation and internalizing transboundary externalities depends critically on the degree of governments susceptibility to foreign political influence

the environmental kuznets curve ekc theory part a concept causes and the co2 emissions case abstract the main purpose of this study is to capture the main features of the environmental kuznets curve ekc concept according to the ekc theory the process of economic growth is expected eventually to limit the environmental degradation created in the early stages of development the ekc concept leads many researchers from the early 1990s to assume that each economy should focus on its growth and any environmental problems will be eventually eliminated by the process of economic growth several studies attempt to test empirically the ekc hypothesis using data on many countries and examining various types of environmental degradation while other studies examine the underlying factors that may drive such a relationship this article reviews the evolution of the ekc concept and the possible causes of an ekc pattern like the distribution of income the international trade pollution haven hypothesis structural changes technical progress and improvements in energy efficiency institutions and governance and consumer preferences as co2 emissions are a pollutant with global effects several studies deal with the possible ekc pattern for co2 emissions and these studies are discussed separately the various critiques on the ekc concept are reviewed in the second article of this work

the multiplier effect of globalization abstract this study uses a three stage common agency model to explore the linkages between trade policy corruption and environmental policy in an imperfect market setting we show that the effect of trade liberalization on the stringency of environmental policy depends critically on the level of corruption in relatively corrupt countries trade openness leads to more stringent environmental policy in such countries this interaction therefore lends trade liberalization a type of multiplier effect raising both economic growth and environmental policy stringency

kyoto protocol cooperation does government corruption facilitate environmental lobbying does environmental lobbying affect the probability of environmental treaty ratification does the level of government corruption play a role for the success of such lobbying in this paper we propose that a more corruptible government may be more responsive to the demands of the environmental lobby we use several stratified hazard models and panel data from 170 countries on the timing of kyoto protocol ratification to test this hypothesis we find that increased environmental lobby group activity raises the probability of ratification and the effect rises with the degree of corruption

environment during growth accounting for governance and vulnerability summary the conventional environmental kuznets curve ekc model holds that pollution inevitably increases until societies reach middle income status because poor countries do not have the institutional capacity or political will to regulate polluters some policy makers and researchers have cited the ekc model when arguing that developing countries should grow first and clean up later however new evidence suggests that this argument is incorrect because it mistakenly assumes that strong environmental governance is not possible for poor countries this paper extends the ekc model to include a new measure of environmental governance as well as a detailed accounting of geographic vulnerability climate and terrain factors we find that these two factors can account for much of the observed variation in developing country air pollution levels

the environmental kuznets curve and sustainability a panel data analysis abstract in recent years sustainability has represented one of the most important policy goals explored in the environmental kuznets curve ekc literature but related hypotheses performance measures and results continue to present a challenge the present paper contributes to this ongoing literature by studying two different ekc specifications for 10 middle east and north african mena countries over the period 1990 2010 using panel data methods for the first specification namely ekc we show that there is an inverted u shape relationship between environmental degradation and income while for the second specification namely modified ekc mekc we show that there is an inverted u shape relationship between sustainability and human development hd the relationships are shaped by other factors such as energy trade manufacture added value and the role of law more interestingly findings from the estimation show that ekc hypothesis hd and sustainability are crucial to build effective environmental policies

environmental performance corruption and economic growth global evidence using a new data set abstractthis study investigates the relationship between environmental performance corruption and economic growth using panel data of 87 countries covering the period from 2002 to 2012 the environmental performance index is used for the first time to evaluate the environmental quality on economic growth by employing both static and dynamic panel models we find that environmental performance is positively related to economic growth and is more significant in non organization for economic cooperation development oecd countries moreover when corruption is incorporated the empirical estimation results indicate that although lower corruption helps economic growth in non oecd countries the negative coefficients of the three interactive terms show that the positive effect of environment performance on economic growth will drop while greater environmental performance combined with natural resource abundance inevitably leads to inefficient bureaucracies and hence disadvantageous economic growth as

the demand for environmental quality in driving transitions to low polluting energy sources the purpose of this paper is to understand the long run demand for energy related environmental quality its influence on legislation and on transitions to low polluting energy sources it starts by presenting a simple framework of the relationship between the demand for and supply of environmental quality environmental legislation and energy this forms the structure for presenting a series of episodes in british history where a demand for improvements in energy related environmental quality existed this analysis proposes that markets can drive transitions to low polluting energy sources in specific economic conditions however most probably governments will need to push them and this cannot be expected without strong and sustained demand for environmental improvements yet while demand is a prerequisite it is not enough it must also be spearheaded by strong creative and sustained pressure groups i e powerful lobbying and the weakening of the counter lobby to introduce legislation to enforce it and to avoid it being over turned by future governments

foreign aid poverty reduction and democracy eradication of poverty is the most pervasive goal of donors foreign aid programmes as a result there has been much research on the degree of correlation between aid and poverty reduction however this work to date has shed little light on the direction of causation between the two variables using the method of granger causality and conditioning aid and poverty on the state of democracy in developing countries this study asks whether aid flows impact poverty whether poverty influences aid flows or whether causality proceeds in both directions simultaneously while the results identify no causal relationships in some of the sub samples they point to the existence of a multitude of relationships across others

pollution shadow economy and corruption theory and evidence abstract we study how the shadow economy affects pollution and how this effect depends on corruption levels in public administration production in the shadow economy allows firms to avoid environmental regulation policies a large informal sector may be accompanied by higher pollution levels our theoretical model predicts that controlling the levels of corruption can limit the effect of the shadow economy on pollution we use panel data covering the period from 1999 to 2005 in more than 100 countries to test this theoretical prediction our estimates confirm that the relationship between the shadow economy and the levels of pollution are dependent on the levels of corruption our results hold when we control for the effects of other determinants of pollution time varying common shocks country fixed effects and various additional covariates

the international response to the threat of chlorofluorocarbons to atmospheric ozone although environmental problems are common in many countries or affect large regions the threats of carbon dioxide induced climate change and depletion of stratospheric ozone are perhaps the most credible global environmental problems presently facing humankind while there are many differences between the co2 and 03 problems the diffuse global hazards share a number of common characteristics the threats are due to anthropogenic chemical changes of a slow cumulative nature early effects may be disguised by normal environmental variation which generates considerable scientific uncertainty by the time all the mechanisms and consequences are known and evaluated it may be too late to avoid the majority of effects which may persist for centuries in addition the climate or stratosphere so affected is not the property of any individual or nation the vulnerable natural and social systems require on going monitoring research and risk assessment as uncertainties are defined and hopefully reduced in short these are threats to the global commons for which there is no precedent in human history this paper examines the different national responses to the threat of chlorofluorocarbon cfc depletion of stratospheric ozone as the first of the global atmospheric problems for which nations have taken concrete action beyond scientific study and risk assessment

does democracy affect environmental quality in developing countries this article examines the impact of democracy on environmental conditions in a large sample of developing countries for the period 1976 2003 this relationship is explored empirically using three indicators of environmental quality carbon dioxide emissions water pollution and deforestation damage we find evidence that democracy is conducive to environmental improvement but that this result depends on the measure of the environmental quality that is used we also find remarkable differences in results across our different sub samples the conclusion therefore is that there is no uniform relationship between democracy and the state of the environment

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

democracy and environmental quality we develop and estimate an econometric model of the relationship between several local and global air pollutants and economic development while allowing for critical aspects of the socio political economic regime of a state we obtain empirical support for our hypothesis that democracy and its associated freedoms provide the conduit through which agents can exercise their preferences for environmental quality more effectively than under an autocratic regime thus leading to decreased concentrations or emissions of pollution however additional factors such as income inequality age distribution education and urbanization may mitigate or exacerbate the net effect of the type of political regime on pollution depending on the underlying societal preferences and the weights assigned to those preferences by the state

globalisation and sustainability environmental kuznets curve and the wto abstract economic globalisation is seen by many as a driving force for global economic growth yet opinion is divided about the benefits of this process as highlighted by the wto meeting in seattle in late 1999 proponents of economic globalisation view it as a positive force for environmental improvement and as a major factor increasing the likelihood of sustainable development through its likely boost to global investment these proponents mostly appeal to analysis based on the environmental kuznets curve ekc to support their views about environmental improvement but ekc analysis has significant deficiencies furthermore it is impossible to be confident that the process of economic globalisation will result in sustainable development if weak conditions only are satisfied strong conditions probably need to be satisfied to achieve sustainable development and given current global institutional arrangements these are likely to be violated by the economic globalisation process global political action seems to be needed to avert a deterioration in the global environment and to prevent unsustainability of development this exposition demonstrates the limitations of ekc analysis identifies positive and negative effects of economic globalisation on pollution levels and highlights connections between globalisation and the debate about whether strong or weak conditions are required for sustainable development the article concludes with a short discussion of the position of wto in relation to trade and the environment and the seemingly de facto endorsement of wto of weak conditions for sustainable development it suggests that wto s relative neglect of environmental concerns is no longer politically tenable and needs to be reassessed in the light of recent developments in economic analysis the skew of economic growth e g in favour of developing countries is shown to be extremely important from a global environmental perspective

corruption illegal trade and compliance with the montreal protocol this paper studies the effects of corruption rule of law and tariffs on illegal trade in chlorofluorocarbons cfcs controlled by the montreal protocol since data on illegal trade is not available it is not possible to test any theoretical conclusions about smuggling the paper however attempts to circumvent the problem by developing a model of illegal trade in cfcs that derives predictions about the effects of corruption rule of law and tariffs on both legal and illegal imports of cfcs then the theoretical predictions concerning legal imports are tested using panel data on cfc consumption using the estimates of legal imports inferences about illegal trade are made the basic findings indicate that knowledge about the degree of rule of law corruption and the level of tariffs is needed for the correct interpretation of the data on environmental performance reported to international monitoring agencies

corruption income and the environment an empirical analysis abstract in response to the recent growth of a largely theoretical body of literature analysing the linkages between corruption and pollution this paper subjects the corruption pollution relationship to a detailed empirical examination a distinction is drawn between the direct impact of corruption on pollution and the indirect impact which operates through corruption s impact on per capita income and the resultant impact of income on pollution using data for 94 countries covering the period 1987 2000 both direct and indirect impacts of corruption on air pollution emissions are estimated for both sulfur dioxide and carbon dioxide corruption is estimated to have a positive direct impact on per capita emissions indirect effects are found to be negative and larger in absolute value than direct effects for the majority of the sample income range as a result the total effect of corruption on emissions is negative for all but the highest income countries in the sample

governance and renewable energy investment in mena countries how does trade matter abstract the middle east and north africa mena countries have recently developed renewable energy re markets however their rate of investment in renewable energy remains small compared to other regions in the world despite their relatively abundant endowments particularly in wind and solar while the literature identifies some barriers to investment in renewable energy we assume that the investment of mena countries could be impeded by specific governance factors furthermore we consider recent literature showing that trade openness reduces the negative effects of weak governance in this paper we empirically investigate the link between governance openness and renewable energy investment in the mena region using panel data for 15 mena countries over the period 1996 2013 our results prove that high institutional quality is associated with re investment in mena countries in addition this relationship seems to be conditional on the trade regime our results are robust to several measures of renewable energy investment and governance as well as to an alternative econometric set up

real business cycle views of the great depression and recent events a review of timothy j kehoe and edward c prescott s great depressions of the twentieth century this book collects essays most of which were published earlier into an advertisement for real business cycle rbc analysis half of the essays discuss the great depression half discuss events of the 1980s and 1990s they all use the general equilibrium model of economic growth to analyze short run fluctuations in the rate of economic growth of various countries i find that the use of closed economy models without frictions is not useful for the analysis of short run variations in the rate of economic growth almost all of these essays end by claiming that variations in the rate of gdp growth were due to changes in the rate of total factor productivity tfp growth they do not provide any explanation for fluctuations in the rate of tfp growth leaving the reader no closer to understanding these periods of depression and slow growth i discuss in turn the essays on the great depression the essays on more recent fluctuations and the definition of great depressions used in this volume

the economic growth debate what some economists have learned but many have not one thing economists should have learned from the economic growth debate is the importance of defining the term growth by growth i mean quantitative increase in the scale of the physical dimensions of the economy i e the rate of flow of matter and energy through the economy from the environment as raw material and back to the environment as waste and the stock of human bodies and artifacts by development i mean the qualitative improvement in the structure design and composition of physical stocks and flows that result from greater knowledge both of technique and of purpose simply put growth is quantitative increase in physical dimensions development is qualitative improvement in non physical characteristics an economy can therefore develop without growing just as the planet earth has developed evolved without growing neoclassical growth models notwithstanding there is good evidence that neither the earth s surface nor the flux of solar energy grows at a rate equal to the rate of interest in fact they seem not to grow at all yet qualitative evolution occurred and continues to occur two general classes of limits to growth in the above defined sense can be further distinguished biophysical limits and ethicosocial limits in both cases it is growth not development that is limited there may or may not exist limits to development but that is another topic standard neoclassical economics was built on the assumption that the economy is far from both limits i e that it is always biophysically possible and ethicosocially desirable for aggregate product to grow as abramowitz l put it echoing pigou

an empirical study of the impact of corruption on environmental performance evidence from panel data this paper extends the empirical debate on the effects of corruption on environmental degradation by considering a recently available measure of environmental quality the environmental performance index this indicator is more comprehensive than the measures of air pollutant emissions commonly used in the literature and in particular can also capture the impact of pollution on human health this allows for a better understanding of the actual effects of a wide range of human activities on the ecosystem from a panel data analysis two regularities emerge first corruption deteriorates the overall environmental quality this effect is robust and persistent second our findings highlight the improvement of environmental quality as income rises even at an initial level of development this is not in contradiction with the ekc hypothesis because an increase in income levels provides positive externalities on the whole environmental quality by compensating the mere negative effects induced by industrialization on the emission levels as a consequence in emerging economies policies fighting corruption and enhancing development are very likely to improve the environmental performances

the impact of environmental regulation shadow economy and corruption on environmental quality theory and empirical evidence from china abstract mounting environmental pressures led china to focus on the effectiveness of the environmental regulation to control pollution since the shadow economy or underground economic activities that are not included in official statistics accounts for an increasing fraction of china s economy its impacts on environmental quality should be carefully evaluated in this study the main research questions are as follows 1 what is the extent of the effect of environmental regulation on environmental quality and 2 what are the factors that influence the impact of environmental regulation on environmental pollution a theoretical model is developed to explain the relationship among the environmental regulation shadow economy and environmental quality in china an empirical analysis is conducted to test the three propositions of the model thereby examining the explanatory power of the theoretical model concretely using panel data from 30 provinces for the period of 1998 2012 the generalized method of moments gmm method is employed to control for potential endogeneity and introduce dynamic effects the estimation results indicate that stringent environmental regulation and the level of the shadow economy are both positively related to china s environmental pollution however the results also indicate that tighter environmental control would help reduce pollution at a given level of the shadow economy moreover an increase in the proportion of corrupt officials may weaken the environmental regulation which would consequently lead to the increase in illegal production and total pollutant emissions besides many economic and social factors may also affect the environmental quality for instance the development of secondary industry contributes toward an increase in pollutant emissions however increased research and development r d spending on eco friendly industrial operations can help to reduce pollution

corruption pollution and the kuznets environment curve abstract this paper examines the implications of corruption and rent seeking behavior by the government for the relationship between pollution and growth cases of both cooperative and non cooperative interaction between the government and the private firm are studied it is shown that corruption is not likely to preclude the existence of an inverted u shaped kuznets environmental curve under both these cases however for any level of per capita income the pollution levels corresponding to corrupt behavior are always above the socially optimal level further the turning point of the kuznets curve takes place at income and pollution levels above those corresponding to the social optimum

corruption and the political economy of resource based development a comparison of asia and sub saharan africa we model how the supply and demand for bribes affects resource use by an economy and the reinvestment of resource rents in other assets this requires adjusting the world bank s measure adjusted net savings for any rent dissipation due to corruption the impacts of corruption on long run changes and periodic growth in the adjusted net savings rate are estimated across african and asian economies from 1970 to 2003 corruption rather than resource dependency per se affects negatively the ability of african countries to reinvest resource rents in the short term but for asian countries corruption is less important than point resources corruption influences long run growth in adjusted net savings rates in all countries and is also the pathway through which this growth is affected by patterns of resource use trade and abundance

ekc type transitions and environmental policy under pollutant uncertainty and cost irreversibility abstract previous studies have suggested that some pollutant levels first increases due to the economic growth and then start decreasing the pattern being called the environmental kuznets curve ekc we examine ekc type transitions of pollutant levels not with respect to economic growth but more generally in time assuming that each policy maker optimally executes the two switching options of regulation and unregulation for pollution the switching dynamics of environmental policy can be described by an alternating renewal process it is shown that the double laplace transform of transition density of a pollutant level can be obtained by a novel application of renewal theory the expected level of overall pollutants is then calculated numerically and found to exhibit either a shaped or an n shaped pattern in time our results present a simple explanation for the ekc type transitions of pollutant levels within a real options framework

aspects of governance and hbox co _2 co 2 emissions a non linear panel data analysis the reduction of hbox co 2 emissions has been at the centre of worldwide debates on environmental issues though its inclusion as one of the millennium development goals mdgs by the united nations has changed the focus of relative literature among many one of the world bank s recipes to achieve a higher position toward mdgs has been to undertake reforms for a better governance while the majority of researches focus has been on one single aspect and its relationship with the environment some studies have simultaneously considered two governance dimensions in this paper we focus on the role of several aspects of governance on hbox co 2 emissions this provides us with a chance to explore the possible impacts of all aspects of governance on a more direct measure of emissions that is different to previous researches which have focused on the indirect transmission and considered the maximum of two using the iv method within panel data analysis we show that only one single aspect of governance control of corruption has a negative significant effect on hbox co 2 emissions and its effect has a non linear relationship the non linearity exists in both parametric and nonparametric analysis after controlling for endogeneity

trade liberalization and environmental degradation in china being aware that trade liberalization affects the environment by scale technique and composition effects this study uses provincial data from 1993 to 2002 in china to empirically investigate how they affect the environment adopting the methodology provided by antweiler et al 2001 and slightly modifying their model this study examines whether the composition effects arising from increasing trade originate due to differences in capital labour endowment factor endowment hypothesis and or differences in environmental regulations accompanied by income growth pollution haven hypothesis in china the results indicate that the evidence of factor endowment hypothesis is found in most of the pollutants studied in this article whilst there seems no evidence of pollution haven hypothesis combining with all the estimated elasticities of scale and technique effects composition effects and trade intensity on emissions i find that increasing international trade has opposite impacts on the environment due t

assessing the role of institutions in limiting the environmental externalities of economic growth emissions of pollutants tend to be procyclical as they generally increase with economic growth however as government policy has a role to play in the mitigation of the environmental consequences of economic activity the quality of institutions may influence the procyclicality of pollution and reduce the environmental cost of economic growth based on the assumption that changes in emissions are stronger at earlier stages of development we develop a non linear framework and confirm first the presence of income related threshold effects in the relationship between pollution co 2 and greenhouse gas emissions and growth for a panel of 142 countries over a period spanning from 1960 to 2017 we also find that institutional quality influences this relationship as the quality of institutions lowers the value of the threshold and the degree of procyclicality of emissions these results bring therefore evidence that higher institutional quality can attenuate the environmental externalities of economic growth

the effect of growth and corruption on soil sealing in italy a regional environmental kuznets curve analysis this paper analyses and looks more closely at the empirical debate regarding the income elasticity hypothesis postulated in relation to the environmental kuznets curve and the impact of corruption on the relationship between growth and environmental impact measured in terms of soil sealing as proxied by the number of building permits issued by public authorities it postulates that when current private rent is high compared to perceived social costs and a large enough minority benefits from the rules the ekc does not emerge and public intervention fails to perceive social optimality to validate this hypothesis we run a panel data regression model based on data from all italian regions results confirmed the hypothesis evidencing a u shaped relationship i e a detrimental relationship between income and environmental impact quality it also demonstrated that this is contingent on the level of corruption the latter affects the position and the shape of the inverted ekc speeding up the exploitation process it shows that the higher the income the higher the effect of corruption on the environment therefore it advocates caution against any simplistic inference from ekc
