total factor productivity and the environmental kuznets curve a comment and some intuition abstract chimeli and braden chimeli ariaster b braden john b 2005 total factor productivity and the environmental kuznets curve journal of environmental economics and management 49 366 380 derive a necessary and sufficient condition under which inter country differences in total factor productivity can yield an environmental kuznets curve they argue that their results emphasize the importance of differences in total factor productivity across countries as well as the need for decreasing returns to scale in pollution abating technologies for the existence of an environmental kuznets curve we show that their proposition 1 is equivalent to proposition 2 in lieb lieb christoph m 2002 the environmental kuznets curve and satiation a simple static model environment and development economics 7 429 448 this implies that even in chimeli and braden s model contemporaneous changes in the marginal rate of substitution between environmental quality and consumption on the demand side and the marginal rate of transformation between these goods on the supply side drive the pollution income relationship this is a very general condition that does not rely on either differences in total factor productivity or decreasing returns to scale in abatement and which is widely applicable

the environmental kuznets curve environmental protection policy and income distribution abstract the effect of economic growth on pollution emissions differs substantially among high income countries i address this issue by analyzing public environmental policy decisions individual heterogeneity relative income effect and the political framework in which policy decisions are taken determine the emergence of the downward sloping segment of the environmental kuznets curve ekc income inequality produces a gap between the country s ability to pay for environmental protection and a country s willingness to pay i test this result by using oecd data on public r d expenditure for environmental protection the conclusion is that contrary to the ek hypothesis moments of the income distribution function other than the mean may be important for the emergence of a virtuous path of sustainable growth in high income countries

equilibrium and efficiency under pure entitlement systems two types of answer have been given to the question of how government should contribute to the happiness of its citizens one is that it should take a direct and perhaps coercive role in the pursuit of optimality or efficiency the other is that it should indirectly promote voluntary cooperation among its citizens by providing procedural justice to them e g enforcement of property rights this paper addresses the question of how cooperative equilibria of a minimal government one which guarantees rights but which does not make direct allocative decisions would compare with social states which are pareto efficient for its citizens specifically it examines whether or not such a government would be unbiased i e whether every pareto efficient social state would be possible to support as a cooperative equilibrium in an environment where its citizens might impose externalities on one another unbiasedness of equilibrium could be interpreted to mean that under ideal circumstances i e that cooperative outcomes would in fact be achieved a minimal government would be procedurally fair however unbiasedness would also imply that such a government could not guarantee an egalitarian distribution of wealth or any other feature except pareto efficiency in an equilibrium social state

assessing income population and technology impacts on co2 emissions in canada where s the ekc abstract this study investigates the macroeconomic forces underlying carbon dioxide co2 emissions from fossil fuel use in canada in keeping with the relevant literature on environmental degradation three forces are expected to influence co2 emissions gross domestic product per capita gdp capita population and technological change while previous work has employed reduced form models that allow for non linear relationships between co2 and gdp capita it has been common practice to assume linear relationships between co2 and the latter two variables this study tests a more flexible model using a five region panel data set in canada over the period 1970 2000 findings indicate that gdp capita is unrelated to co2 that an inverted u shaped relationship exists with population and that a u shaped relationship exists with technology thus technological and population changes are supported over the commonly hypothesized environmental kuznets curve an inverted u shaped relationship between gdp capita and environmental degradation for affecting co2 emissions from fossil fuel use in canada

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

technological vs ecological switch and the environmental kuznets curve we consider an optimal technology adoption ak model in line with boucekkine krawczyk and vallee 2011 an economy caring about consumption and pollution as well starts with a given technological regime and may decide to switch at any moment to a cleaner technology at a given permanent or transitory output cost at the same time we posit that there exists a pollution threshold above which the assimilation capacity of nature goes down featuring a kind of irreversible ecological regime we study how ecological irreversibility interacts with the ingredients of the latter optimal technological switch problem with a special attention to induced capital pollution relationship we find that if a single technological switch is optimal one recovers the environmental kuznets curve provided initial pollution is high enough if exceeding the ecological threshold is optimal then the latter configuration is far from being the rule

the vaccination kuznets curve do vaccination rates rise and fall with income abstract this paper presents a new stylized fact about the relationship between income and childhood vaccination it shows vaccination rates first rise but then fall as income increases this pattern is observed in who country level panel data and in us county level panel and individual level repeated cross section data this data pattern suggests that both low and high income parents are less likely to follow the standard vaccination schedule and that such behavior is reflected in the vaccination rate at the population level i provide several alternative explanations as to why we observe this data pattern including avoidance measures medical care and social segregation

does central supervision enhance local environmental enforcement quasi experimental evidence from china abstract this paper draws on a natural experiment generated by the national specially monitored firms nsmf program in china to evaluate the effectiveness of central supervision at improving local environmental enforcement we explore a unique firm level chinese environmental statistics dataset and utilize a regression discontinuity design to assess the impact of central supervision through the nsmf program on an industrial firm s chemical oxygen demand cod emissions the results suggest that central supervision significantly reduces industrial cod emissions by at least 26 8 these results highlight the substantial room for improvement in chinese environmental regulations via central supervision a more flexible environmental decentralization regime and comprehensive central supervision are thus recommended for future reforms

no regret pollution abatement options a correction of brechet and jouvet 2009 in why environmental management may yield no regret pollution abatement options ecological economics 2009 brechet and jouvet claim to have theoretically shown that profits maximizing firms can reduce pollution compared to laissez faire and increase their profits we correct multiple errors in their paper with the conclusion that their claim no longer stands

the environmental kuznets curve and the role of coal consumption in india cointegration and causality analysis in an open economy abstract this study investigates the dynamic relationship between coal consumption economic growth trade openness and co2 emissions in case of india in doing so narayan and popp journal of applied statistics 2010 37 1425 1438 structural break unit test is applied to test the order of integration of the variables long run relationship between the variables is tested by applying the ardl bounds testing approach to cointegration developed by pesaran et al journal of applied econometrics 2001 16 289 326 the results confirm the existence of cointegration for long run between coal consumption economic growth trade openness and co2 emissions our empirical exercise indicates the presence of environmental kuznets curve ekc in long run as well as in short run coal consumption as well as trade openness contributes to co2 emissions the causality analysis reports the feedback hypothesis between economic growth and co2 emissions and same inference is drawn between coal consumption and co2 emissions moreover trade openness granger causes economic growth coal consumption and co2 emissions

is trade good or bad for the environment sorting out the causality we seek to contribute to the debate over globalization and the environment by asking what is the effect of trade on a country s environment for a given level of gdp we take specific account of the endogeneity of trade using exogenous geographic determinants of trade as instrumental variables we find that trade tends to reduce three measures of air pollution statistical significance is high for concentrations of so2 moderate for no2 and lacking for particulate matter although results for other environmental measures are not as encouraging there is little evidence that trade has a detrimental effect on the environment

climate change policy what do the models tell us very little a plethora of integrated assessment models iams have been constructed and used to estimate the social cost of carbon scc and evaluate alternative abatement policies these models have crucial flaws that make them close to useless as tools for policy analysis certain inputs e g the discount rate are arbitrary but have huge effects on the scc estimates the models produce the models descriptions of the impact of climate change are completely ad hoc with no theoretical or empirical foundation and the models can tell us nothing about the most important driver of the scc the possibility of a catastrophic climate outcome iam based analyses of climate policy create a perception of knowledge and precision but that perception is illusory and misleading jel c51 q54 q58

the fate of easter island the limits of resource management institutions abstract malthus malthus thomas 1798 1970 an essay on the principle of population penguin new york believed that population growth will eventually lead to natural resource depletion economic and social collapse and population decline brander and taylor brander james a taylor m scott 1998 the simple economics of easter island a ricardo malthus model of renewable resource use american economic review 88 119 138 use a predator prey model with an assumption of an open access resource they show that the collapse of easter island could be explained by a malthusian trap combined with technical characteristics of the resources they suggest that institutional change such as assignment of property rights could potentially have averted the collapse of easter island in this paper we show that even if the islanders had complete assignment of property rights and implemented optimal resource management with infinite horizon or equivalently had a social planner that implemented such an optimal plan as in neoclassical welfare economics a similar boom bust cycle would have occurred

trade liberalization and environmental taxation in federal systems the literature on trade liberalization and environment has not yet considered federal structures in this paper we show how the design of environmental policy in a federal system has implications for the effects of trade reform trade liberalization leads to a decline in pollution taxes regardless of whether pollution taxes are set at the federal centralized or local decentralized level and it increases social welfare the effect under a decentralized system is smaller than if these taxes are set by the federal government and pollution emissions therefore decline in this case moreover majority bias interacts with trade liberalization if federal taxes are used

polluting non renewable resources and growth in an endogenous growth model with human capital accumulation we introduce non renewable resources which cause flow pollution problems in this set up the negative external effect of pollution on productivity does not cause any distortions in the economy the market economy will achieve the optimal extraction and growth rates consequently emission taxes are unnecessary and when introduced will have no effect on the economy the more important is the negative pollution externality the larger will be the optimal long run growth rate which may be either positive or negative in the case of a positive human capital externality consumption in the market economy may approach zero in the long run although positive consumption growth is socially optimal growth enhancing policies do not necessarily cause a larger drain in the resource stock

the feasibility of the double dividend hypothesis in a democratic economy the two dividends in the double dividend hypothesis are assumed to be independent this assumption can be misleading when it comes to formulating policy i construct a model where the pollution tax rate is voted for by heterogeneous people in addition to the revenue recycling effect the equilibrium pollution tax rate depends on two opposite forces the tax cutting effect and the profit effect the two forces show that an instrument that exploits a greater revenue recycling effect can cause a more severe environmental deterioration thereby resulting in the infeasibility of the hypothesis the introduction of the interdependence between the two dividends can also mean that non revenue raising instruments are more efficient than revenue raising instruments

north south trade and industry specific pollutants abstract this paper investigates the production and pollution patterns arising from trade between high and low income countries when firms discharge industry specific pollutants we extend the common pollutant model of copeland and taylor north south trade and the environment quart j econ 109 1994 755 787 to incorporate industry specific pollutants and obtained a diversified equilibrium which differs markedly from the complete specialization equilibrium obtained in the original model with diversified production individual countries shares of production and emissions change in a flexible manner reflecting the competitiveness of their products in the world market this result makes it easier for empirical studies to test the theoretical relationships between industrial production emissions and the different attributes of countries including income and factor endowment despite the striking difference in the equilibrium patterns of production and emissions the prediction of the pollution haven hypothesis is retained and pollution intensive industries relocate to south finally a composite of pollutants weighted by disutilities increases in south and decreases in north

public acceptance for environmental taxes self interest environmental and distributional concerns abstract while strongly recommended by economists it has often been politically difficult to impose taxes on externalities there is a substantial literature on public attitudes towards environmental taxes there has however been few comprehensive attempts to understand attitudes towards environmental taxes the main research question in this paper is which factors influence support for fuel taxation we propose a model of attitudes towards fuel taxation and test this model as well as more specific hypotheses using data from a representative survey of the adult norwegian population our results suggest that support for fuel taxation is best predicted by beliefs about environmental consequences followed by beliefs about consequences to others beliefs about consequences to self self interest is the factor that explains the least variation in support for fuel taxation the academically interesting result that support cannot be well explained without capturing a broad range of motivational factors is also highly policy relevant it implies that there is no magic formula for increasing public support for environmental taxes there are however some issues which can be addressed trust in how well the government spends the revenue and the perception that taxation does very little to change behaviour and thus to reduce environmental problems

does anticipated aggregate demand policy matter further econometric results a heated debate has arisen over what modigliani has dubbed the macro rational expections mre hypothesis this hypothesis embodies two component hypotheses 1 rational expectations and 2 short run neutrality i e that anticipated changes in aggregate demand will have already been taken into account in economic agents behavior and will thus evoke no output or employment response together these component hypotheses imply that deterministic feedback policy rules will have no effect on business cycle fluctuations the irrelevance of these types of policy rules is inconsistent with much previous macro theorizing as well as with the views of policymakers it is thus an extremely controversial proposition which requires a wide range of empirical research this paper is a sequel to a previous paper by the author that paper developed a methodology for testing the mre hypothesis and found that anticipated money growth does matter to the business cycle this paper extends the analyses to cases where the rate of nominal gnp growth or the inflation rate rather than money growth is the aggregate demand variable the empirical results are also negative on the mre hypothesis and its corresponding policy ineffectiveness proposition this abstract was borrowed from another version of this item

environmental policy and growth when inputs are differentiated in pollution intensity environmental policy affects the distribution of market shares if intermediate goods are differentiated in their pollution intensity when innovations are environment friendly a tax on emissions skews demand towards new goods which are the most productive in this case the tax has to increase along a balanced growth path to keep the market shares of goods of different vintages constant comparing balanced growth paths we find that tightening the policy stance spurs innovation because it increases the market share of recent vintages and promotes environment friendly technological progress as a result the cost of environmental policy in terms of slower growth is weaker

on a clear day you might see an environmental kuznets curve we shed some new light on the environmental kuznets curve ekc and show how it can be viewed as a particular form of equilibrium relationship where technology and preference parameters determine the shape of the curve in contrast to most of the literature on the ekc we estimate a theoretically consistent model on long run data swedish sulfur emission covering the period 1900 2002 furthermore we test and date structural change the model suggests four regimes 1900 1918 1919 1933 1934 1967 and 1968 2002 generating four rather different patterns for pollution over time the policy conclusions are consonant with pearce s general view about the ekc there is no theoretical presumption that it has an inverted u shape nor should any country try to grow out of the environmental problems without analyzing the benefits and costs of so doing

the impact of economic growth on co2 emissions in azerbaijan abstract this paper investigates the relationship between the economic growth and co2 emissions in azerbaijan a cointegration analysis is conducted over the period 1992 2013 for getting more robust results johansen ardlbt dols fmols and ccr methods are employed to explore cointegration and estimate long run coefficients we use cubic quadratic and linear specifications and conclude that the last one is an adequate representation for the impact of the economic growth on co2 emissions in azerbaijan the results from the different cointegration methods are consistent with each other and show that the economic growth has a positive and statistically significant impact on the emissions in the long run implying that the ekc hypothesis does not hold for azerbaijan the income elasticity of co2 emissions using different methods is found to be between 0 7 and 0 8 moreover we find that any short run imbalance can be adjusted towards the long run equilibrium path within less than one year the paper concludes that measures to increase energy efficiency carbon pricing instruments in production and international domestic trade activities and nationwide social awareness programs to instruct about the negative consequences of pollution can be considered as relevant environmental policies aimed at reducing carbon emissions

regime switching approach to monetary policy effects even though monetary policy has kept interest rates at historically low levels the japanese economy has experienced long lasting recessions since the 1990s in this paper japanese data are employed to conduct an empirical analysis of changes in the effects of monetary policy on the real economy it is found that monetary policy effects vary depending on the phase of the business cycle and the lending attitudes diffusion indices more precisely policy effects are larger in recession but diminish in extreme recession and monetary policy is more effective when lenders attitudes are severe but less effective when they are excessively severe

the growth of social security electoral push or political pull the growth of social security electoral push or political pull i introduction during the post world war ii period the social security program was among the fastest growing programs in the federal budget surpassing defense spending as the largest category of expenditures in the mid seventies the program which disbursed only 132 million dollars in 1942 disbursed more than 156 billion dollars forty years late a thousand fold increase as a consequence of this growth and the program s recent financial problems a number of economists have turned their attention to the economics of social security recent examples include kahn 1988 boskin et al 1987 and veall 1986 yet only weaver 1982 and turner 1984 attempt to analyze the growth of the social security program weaver s legislative history of the program suggests that special interest groups had a major impact on social security programs turner argues that program benefit levels are affected by demographic changes which affect the cost of intergenerational redistribution in this paper we use the public choice approach to explain increases in benefit levels from 1946 1980 we develop and test three alternative public choice models of the politics of retirement benefit levels our analysis thus sheds light on an important question neglected by previous research have social security expenditures grown because special interest groups have effectively captured the congress or is congress simply responding to demands placed on it by the electorate the answer to this question is relevant to normative analysis of existing programs and to alternative proposals for reform in addition our study of the principal determinants of the growth of program benefit levels serves as an event study for assessing the merits of alternative theories of political decision making borcherding 1985 discusses two public choice explanations for the growth of public expenditures first public programs may expand as a result of the voting rules which underlie the political process when decisions are made by majority rule an increase in the median voter s demand for public services tends to increase public service levels because prospective candidates will revise their policy positions in order to be elected the wagner 1958 hypothesis for example maintains that increases in real income cause individuals to prefer both absolutely and relatively larger public expenditures borcherding notes that about 40 percent of the rate at which public sector spending has replaced private sector spending over the past eighty years can be explained with a median voter approach such an approach does better in what borcherding calls traditional areas of public expenditure where a median voter model can account for about 73 percent of the rate at which public expenditures excluding transfers have displaced private expenditures the median voter might favor public transfers to the elderly for two reasons first he may have an interdependent utility function in which the plight of the elderly poor arouses a charitable response while the redistribution from young to old does not simply target the old poor as a group the elderly do seem to be relatively less wealthy than the middle aged and the yound if one considers the average capitalized value of future income receipts from labor and capital second to the extent that the social security program offers a connection between reductions in current consumption and increases in future consumption it is a rather complex savings and insurance program the median voter s motivation for transferring monies to today s elderly may be a vehicle for ensuring future transfers to himself while this explanation is difficult to motivate at the individual level since a savings program for future retirement need not pay anything to today s elderly a continuing program of tax funded transfers is plausible method of establishing the moral constitution necessary to ensure that future transfers do in fact take place

multiple equilibria in a stochastic implementation of dice with abrupt climate change abstract integrated assessment modeling of global climate change has focused primarily on gradually occurring changes in the climate system however atmospheric and earth scientists have become increasingly concerned that the climate system may be subject to abrupt discontinuous changes on short time scales and that anthropogenic greenhouse gas emissions could trigger such shifts incorporating this type of climate dynamics into economic or integrated assessment models can result in model non convexity and multiple equilibria and thus complicate policy analysis relative to models with unique globally optimal policies using a version of the nordhaus dice model amended in previous research by keller et al 2004 keller klaus benjamin m bolker david f bradford 2004 uncertain climate thresholds and optimal economic growth journal of environmental economics and management 48 1 723 741 in conjunction with a stochastic global optimization algorithm we generate level sets of solutions which helps identify multiple equilibria resulting from the potential abrupt cessation of the north atlantic thermohaline circulation we discuss the implications of this model geometry for formulating greenhouse gas abatement policy under uncertainty and suggest that this general approach may be useful for addressing a wide range of model non convexities including those related to endogenous technological change

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

efficient dynamic pollution taxation in an uncertain environment this paper analyzes efficient pollution taxation within a stochastic model of endogenous growth pollution is a by product of production and causes disutility furthermore the productivity which results from environmental quality is uncertain this reflects e g uncertain capital depreciation induced by natural disasters like hurricanes or floods this uncertainty is shown to raise an ambiguous impact on the optimal pollution level as well as on optimal environmental taxation market equilibrium turns out to be suboptimal since the households mis perceive their individual impact on pollution conditions for welfare maximizing pollution taxation are stated and it is shown that a direct pollution tax is not appropriate to yield pareto optimal growth instead a linear capital income tax together with a linear abatement subsidy build an efficient tax scheme if secondarily the governmental budget is balanced moreover an increase in the riskiness of environmental productivity may even lead to an increase in the optimal pollution level and to a decrease in optimal environmental taxation depending predominantly on the preference parameters

transboundary externalities in the environmental transition hypothesis the environmental kuznets curve ekc is a hypothesis which implies that it is possible to grow out of environmental degradation most theoretical models of the ekc relation have not accounted for transboundary and intergenerational externalities nor have empirical studies provided evidence that validates an inverted u shaped relation between environmental degradation and economic growth for pollution problems where the effects are far displaced or are long delayed

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

demand for environmental goods evidence from voting patterns on california initiatives this article studies voting behavior on 16 environmental ballot propositions in california in order to characterize the demand for environmental goods the environment is found to be a normal good for people with mean incomes but some environmental goods are inferior for those with high incomes at least when supplied collectively an important price of environmental goods is reduced income in the construction farming forestry and manufacturing industries income and price can explain most of the variation in voting there is little need to introduce preference variables such as political ideology

the environmental kuznets curve and equilibrium indeterminacy abstract we illustrate that the existence of the environmental kuznets curve ekc could be the result of indeterminacy of equilibria in a simple neoclassical growth model with a single environmental externality in households utility function and with public abatement we characterize the condition on the parameters in preferences and in the pollution technology leading to local indeterminacy of equilibrium estimates of the crucial parameters of the model using data from economies that display the ekc satisfy the theoretical indeterminacy condition we find that the presence of abatement activities is not a necessary condition for indeterminacy equilibria and hence an ekc to arise on the other hand non separability of consumption and pollution in the utility function is crucial

carbon capture and storage and transboundary pollution a differential game approach abstract we study the strategic behavior of two countries facing transboundary co2 pollution under a differential game setting in our model the reduction of co2 concentration occurs through the carbon capture and storage process rather than through the adoption of cleaner technologies furthermore we first provide the explicit short run dynamics for this dynamic game with symmetric open loop and a special markovian nash strategy then we compare these strategies at the games steady states and along some balanced growth paths our results show that if the initial level of co2 is relatively high state dependent emissions reductions can lead to higher overall environmental quality hence feedback strategy leads to less social waste

natural disasters in a two sector model of endogenous growth using an endogenous growth model with physical and human capital accumulation this paper considers the sustainability of economic growth when the use of a polluting input e g fossil fuels intensifies the risk of capital destruction through natural disasters we find that growth is sustainable only if the tax rate on the polluting input increases over time the long term rate of economic growth follows an inverted v shaped curve relative to the growth rate of the environmental tax and it is maximized by the least aggressive tax policy of those that asymptotically eliminate the use of polluting inputs unavailability of insurance can accelerate or decelerate the growth maximizing speed of the tax increase depending on the relative significance of the risk premium and precautionary savings effects welfare is maximized under a milder environmental tax policy especially when the pollutants accumulate gradually

swedish co2 emissions 1900 2010 an exploratory note abstract this paper projects swedish co 2 emissions during the period 2000 2010 based on data covering 1900 1999 swedish climate policy is currently based on the assumption that carbon emissions will increase ceteris paribus by 5 15 relative to the 1990 level this forecast has motivated a number of policy measures including carbon taxes subsidies and an information package we find however that co 2 emissions may well be lower in the future this outcome is broadly consistent with the literature on the environmental kuznets curve which portrays the relationship between emissions and gdp the key contribution of this paper is that our analysis is based on a long time series current literature is invariably based on short panel data sets while we study a single country through several phases of development our analysis also sheds some light on the key importance played by nuclear power for carbon emission projections

price level determinacy with an interest rate policy rule and rational expectations abstract this paper reconsiders a result obtained by sargent and wallace namely that price level indeterminacy obtains in their model if the monetary authorities adopt a feedback rule for the interest rate rather than the money stock it is shown that the indeterminacy vanishes if the interest rate rule is chosen so as to have a desired effect on the expected quantity of money demanded this holds even if considerable weight is given in the choice of a rule to the aim of smoothing interest rate fluctuations

economic development and the energy intensity of human well being evidence from the gcc countries abstract this paper empirically investigates the effect of economic development on the energy intensity of human well being eiwb in the gulf cooperation council gcc during the period 1995 2012 we employ a time series cross sectional prais winsten regression model with panel corrected standard errors pcse we conclude that economic development has had a significant positive impact on eiwb during the period 1995 2012 the results indicate that the stress on the environment had increased in a noticeable manner from 1995 until 2006 however over the period 2007 2012 the stress went back to the level observed in 1995 this observation is unfortunate from the perspective sustainable economics

scarcity growth and r d abstract the limits to economic growth due to resource scarcity can be alleviated only by the development of backstop substitutes this paper combines resource based economic growth with r d to reduce the cost of backstop technologies characterizing the entire dynamics of optimal growth and r d processes we find that an economy s growth prospects depend on its type as determined by its production technology and learning ability and by its knowledge capital endowment a wide variety of growth patterns emerges ranging from cases in which an economy that without r d eventually stagnates converges to a steady state is diverted by r d onto a path of sustained growth to cases in which r d is not warranted resource scarcity is shown to encourage r d due to the increased reliance on the backstop technology

is the income elasticity of environmental improvements less than one we estimated the income elasticity of environmental improvements for a number of european data sets the value of this parameter is consistently found to be less than one with few exceptions our findings are compared with state of the art contingent valuation studies from other countries we also compared our findings with those reported in the literature on charitable donations and corporate donations these studies show a similar pattern donations decrease as a percentage of income as income increases

harmonizing tailpipe policy in symmetric countries improve the environment improve welfare abstract we show that harmonizing emissions policy may be bad for the environment and or global welfare even when pollution is transboundary and countries are identical in every way harmonization effectively internalizes the transboundary aspects of pollution but it also changes the politics surrounding tailpipe regulation with harmonization producers can no longer avoid strict local regulation by simply exporting their products to overseas markets with weak standards for consumer goods as a result harmonization may raise political opposition to regulation to examine these competing effects we develop a generic treatment of the politics of environmental regulation a treatment we show to be isomorphic to three popular models of political economy majority rules a political elite and a political contributions approach we find that harmonization both weakens environmental regulation and reduces global welfare when the level of political capture by dirty industry is high relative to the rate of pollution transmission across borders

determinants of local school spending some consistent estimates the traditional median voter model predicts that median income and taxprice are the primary determinants of local school spending levels it further implies that lump sum grants wills be utilized like private income and thus income and grant coefficients should be the same our comprehensive search technique shows that excluding equalized assessed value these predictions hold up quite well over 2048 specifications income and taxprice elasticities are reasonable and tightly distributed with income and blockgrant effects of the same general size as note above any hint of flypaper effect is completely dependent on the inclusion of equalized assessed value in the regression equation since the state of new york has annual district level tax levy elections it would be hard to rationalize bureaucratic power or agenda control as capable of producing flypaper type effects so this absence is not surprising future research should 1 investigate the specification sensitivity of flypaper effects with other datasets and wealth variables and 2 examine election and tax rules for the possibility of budget maximizing actions by school officials finally the consistently positive effects of private schooling nonwhite and in poverty suggest that future work should attempt to model non linear income effects

are there limits to growth a simple theoretical model of pollution is developed that generates an inverted u shape relationship between per capita income and environmental quality this model is then used to study long run growth the same inverted u shape is shown to appear in time series and the prospects for sustained growth are shown to hinge on whether increasingly strict environmental regulation is compatible with a constant rate of return on capital implementation is also studied tax and voucher schemes are shown to have an advantage over direct regulation because they provide the correct incentives for capital accumulation copyright 1998 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

output emissions and technology some thoughts abstract the principal goal of this article is to identify the implications of a binding emission constraint on a firm s optimal capital labor ratio and to determine whether it is appropriate to write a firm s production function as an increasing function of its emissions alone i find that even though a firm s supply curve may be written as a positive function of its emissions it is not appropriate to write the production technology as an increasing function of only its emissions except under special circumstances

are there increasing returns to pollution abatement empirical analytics of the environmental kuznets curve in pesticides abstract according to the environmental kuznets curve ekc hypothesis economic growth and the reduction of environmental degradation are compatible goals an inverted u shaped relationship between economic performance and environmental pollution suggests that empirically an economy is associated with smaller levels of pollution after some threshold income point one potential explanation for the empirical evidence of an ekc is increasing returns to pollution abatement where the abatement efficiency rises with an increase in the scale of abatement doubling the clean up efforts more than doubles the abatement of pollution as this efficiency gain makes abatement less expensive pollution might fall as more abatement is undertaken this study tests the hypothesis that there are increasing returns to abating pollution empirical evidence on environmental risks in the us agricultural sector since 1970 support the existence of increasing returns in addition i estimate the productivity of pollution abatement using refined empirical productivity measurement methods and explicitly control the level of technology the results show the importance of including an environmental productivity variable in the ekc framework

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

sustainable growth and the environmental kuznets curve abstract this paper develops an endogenous growth model with pollution and both human and physical capital human capital is produced cleanly and physical capital can be used for pollution control economic growth is sustainable in the long run it is optimal for human capital to grow more rapidly than physical capital output and consumption while pollution declines for realistic parameter values our results differ sharply from stokey s result for an ak technology that sustained economic growth is not optimal the model can generate an environmental kuznets curve a pollution tax or a voucher system can implement the pareto efficiency solution

technical progress structural change and the environmental kuznets curve abstract the paper shows that under reasonable assumptions about technical progress a positive sustainable growth rate fails to exist the argument is that a growing part of income has to be spent for continuing technical progress in order to compensate the pollution effects of growth hence in the long run either the sustainability condition will be violated or the growth rate must decline to zero furthermore in finite time the level of wealth will decrease despite growing income and a constant pollution level thus further growth is no longer reasonable similar arguments also hold for the environmental effects of structural change favoring less pollution intensive economic activities an evolutionary change of goods and production technology may shift the limits of growth and is hence a prerequisite for a long run ekc

smooth transition pollution income paths abstract we explore the idea of regime switching as a new methodological approach in the analysis of the emission income relationship the basic idea is that when some threshold is passed the economy could move smoothly to another regime with the emission income relationship being different between the old and the new regime the methodology is applied to a panel dataset of us state level sulfur dioxide and nitrogen oxide emissions sulfur dioxide emissions are found to smoothly peak at a relatively late stage of economic development and then smoothly decrease at high levels of income however for the nitrogen oxide emissions environmental pressure tends to rise with economic growth then slows down but does not decline with further growth

the trade off between income inequality and carbon dioxide emissions abstract we investigate the theoretically ambiguous link between income inequality and per capita carbon dioxide emissions using a panel data set that is substantially larger in both regional and temporal coverage than those used in the existing literature using an arguably superior group fixed effects estimator we find that the relationship between income inequality and per capita emissions depends on the level of income we show that for low and middle income economies higher income inequality is associated with lower carbon emissions while in upper middle income and high income economies higher income inequality increases per capita emissions the result is robust to the inclusion of plausible transmission variables

carbon prices for the next hundred years this paper examines the socially optimal pricing of carbon emissions over time when climate change impacts are unknown potentially high consequence events the carbon price tends to increase with income but learning about impacts or their absence decouples the carbon price from income growth the price should grow faster than the economy if the past warming is not substantial enough for learning the true long run social cost it grows slower than the economy as soon as the warming generates information about events that could have arrived but have not done so a quantitative assessment shows that the price grows roughly at the rate of the economy for the next 100 years

the optimal timing of adoption of a green technology we study the optimal timing of adoption of a cleaner technology and its effects on the rate of growth of an economy in the context of an ak endogenous growth model we show that the results depend upon the behavior of the marginal utility of environmental quality with respect to consumption when it is increasing we derive the capital level at the optimal timing of adoption we show that this capital threshold is independent of the initial conditions on the stock of capital implying that capital poor countries tend to take longer to adopt also country specific characteristics as the existence of high barriers to adoption may lead to different capital thresholds for different countries if the marginal utility of environmental quality decreases with consumption a country should never delay adoption the optimal policy is either to adopt immediately or if adoption costs are too high to never adopt the policy implications of these results are discussed in the context of the international debate surrounding the environmental political agenda

pollution income dynamics this paper integrates the scale composition and technique effects of economic growth on pollution using a multi output endogenous growth framework under certain empirically verifiable parameter conditions economic growth is not sustainable even under an optimal pollution tax

towards an integrated framework for development and environment policy the dynamics of environmental kuznets curves abstract environmental kuznets curves ekcs have recently received considerable attention in development and environment policy but little is known on how the interaction between ecological and economic factors may result in an ekc or other qualitatively different outcomes we introduce a restricted class of vector valued differential equations for representing the evolution of socioeconomic and environmental variables which influence or are influenced by the process of economic development our model includes not only the complete path of each variable over time but also the highly critical interactions among multiple variables we demonstrate analytically and numerically that among a multiplicity of possible outcomes an inverted u pattern can only be obtained under specific circumstances and requires attention to the multiple factors which form the economic environmental system rather than a single dominant one

models as usual for unusual risks on the value of catastrophic climate change we study the role of alternative intertemporal preference representations in a model of economic growth stock pollutant and endogenous risk of catastrophic collapse we contrast the traditional discounted utility model which assumes risk neutrality with respect to intertemporal utility with a multiplicative choice model that displays risk aversion in that dimension first we show that both representations of preferences can rationalize the same business as usual economy for a given interest rate and no pollution externality second once we introduce a collapse risk whose hazard rate is a function of the pollution stock multiplicative preferences recommend a much more stringent policy response an illustration in the context of climate change indicates that switching to the multiplicative preference representation has a similar effect in terms of policy recommendations as scaling up the schedule of the hazard rate by a factor of 100

renewable resources in an endogenously growing economy balanced growth and transitional dynamics abstract we introduce a renewable resource sector into an endogenous growth model of a small economy deriving the transitional dynamic equilibrium the model generates a long run equilibrium in which a resource sector of limited size can coexist with constant ongoing growth elsewhere the key feature of the model is the allocation of labor between harvesting the resource and its use in the final output sector this naturally generates the empirically observed negative relationship between resource abundance and growth we examine both the dynamic and long run responses of the economy to various shocks pertaining to technological production conditions and resource sector parameters

voting for environmental policy under income and preference heterogeneity we examine the design of policies for promoting the consumption of green products under preference and income heterogeneity using organic food products as an example two instruments are considered a price subsidy for the organic food products and a tax on the conventional products under income disparity consumers with high income always prefer a socially optimal subsidy to a socially optimal tax while low income consumers prefer a tax on conventional products when environmental policy is determined by the median voter the policies implemented tend to be stricter than socially optimal policies if income differences are large

climate change and uneven development in this paper using a theoretical model with endogenous capital depreciation we study the effects of climate change and adaptation on long run development we show that climate change affects economic growth depending on climate exposure and adaptation efficiency which are asymmetric between different countries poor countries are likely to be hurt more because of the negative effects of climate change on the rate of depreciation of the assets that represent the engine of growth these asymmetries generally induce growth deficits and unsustainability traps in less developed economies

the environmental kuznets curve and the structural change hypothesis we provide a very simple macroeconomic investigation of the role that structural changes might play in generating inverted u shaped income pollution relationships differently from previous research which mainly focuses on empirical static or general equilibrium models we develop a standard balanced growth path bgp analysis we show that along the bgp equilibrium an inverted u shaped income pollution relationship may occur as a response to structural changes but whether this is the case or not it will crucially depend upon the magnitude of a production externality parameter moreover we show that the negative relationship between income and pollution can only be a transitory phenomenon and in the long run pollution will increase as income rises generating overall an n shaped pattern

trading rules and the environment does equal treatment lead to a cleaner world abstract in this paper we consider a three stage game in the context of a competing exporters model to compare and contrast the effects of discriminatory and uniform most favored nation mfn tariffs on countries choice over environmental standards for varying degrees of pollution spillovers because of the presence of punishment effects and stronger own and cross tariff effects we find that discrimination yields higher standards than mfn and free trade independently of the extent of pollution spillovers when pollution is local and incentives to free ride on other countries abatement efforts are weak we show however that welfare is larger under mfn than under discrimination in a dynamic setting we consider the impact of symmetric and asymmetric treatments on the sustainability of an international environmental agreement iea and obtain that multilateral cooperation is easier to sustain under discrimination than under mfn or free trade

trade politics and the environment tailpipe vs smokestack abstract the vast majority of economic research on environmental regulation in open economies focuses on producer generated smokestack pollution we instead consider consumer generated tailpipe pollution we examine how political opposition to environmental regulation varies with a country s trade regime and show that the impact on environmental policy of a move from autarky to free trade can depend critically on who ultimately generates pollution producers or consumers we find that opening to trade may raise industry opposition to smokestack regulation but reduce its opposition to strict tailpipe policy

intra industry trade in intermediate products pollution and internationally increasing returns this paper examines the relationship between intra industry trade in intermediate products pollution and increasing returns we develop a two country model in which production occurs in two stages final and intermediate good production intermediate goods are produced under monopolistic competition and final good production exhibits increasing returns with respect to the number of varieties of intermediates pollution occurs in the production of the final good when polluting intermediates are used we analyze the effects of international trade in intermediate products on pollution output and welfare under an endogenous tax scenario and with two types of pollution functions the results show that because of increasing returns international trade either leads to lower total pollution in each country or lower pollution per unit of output in at least one country in addition intra industry trade causes countries to import the environmental quality of their trading partners

a tradable permit system in an intertemporal economy it is known that in an intertemporal competitive economy a tradable permit system may not achieve efficiency without setting appropriate permit interest rates i e rewards for holding permits to find the rates however we need to know in advance the path of efficient permit prices which is difficult to obtain this study intends to solve this problem in two ways first we analyze a special case in which the permit interest rates are given by a simple rule for example if the marginal abatement cost of pollution emission is constant then the appropriate rate is to equal the monetary interest rate as is the case for global warming if the damage is caused in the future far beyond the planning period of the environmental program the appropriate rate coincides with the marginal self recovery of environmental stock under certain conditions as a second approach we propose a tradable permit system with a permit bank as a mechanism by which the permit interest rates are generated endogenously without governmental intervention other than the issuance of permits however we also show that this approach raises the problem of indeterminacy of the equilibrium

green attitude and economic growth we analyze the interdependence between green attitude and equilibrium development of environmental quality in an endogenous growth model individuals take only part of their impact on pollution into account hence there is a negative externality of capital accumulation on environmental quality increasing wealth or increasing pollution enhance green attitude and reduce the externality because individuals care more about the environment if their income is higher or if pollution is more obvious the time path of pollution as well as the evolution of equilibrium growth are shown to depend crucially on the determinants of green attitude ongoing growth may lead to complete internalization of the environmental externality if green attitude improves with increasing wealth e g as a consequence of an increase in environmental education in contrast if green attitude is determined exclusively by the level of environmental quality pollution remains at a suboptimally high level the interdependence of wealth and pollution in the determination of environmental awareness implies more complex dynamics capital growth enhances green attitude and thereby decreases pollution improved environmental quality in turn may increase capital growth due to less green attitude and therefore slow down convergence to the sustainable balanced growth path

taking the u out of kuznets a comprehensive analysis of the ekc and environmental degradation unlike most environmental kuznets curve ekc studies which focus on narrow measures of pollution as proxies for environmental quality we test the validity of the ekc using the ecological footprint ef a more comprehensive measure of environmental degradation we find no empirical evidence of an ekc relationship between the ef and economic development and only limited support for such a relationship among the components of the ef in addition we discover that energy is largely responsible for the lack of an ekc relationship and that energy consumption levels would have to be cut by over 50 in order for a statistically significant ekc relationship to emerge from the data overall these results suggest that growth alone will not lead to sustainable development

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

a tale of two elasticities a general theoretical framework for the environmental kuznets curve analysis abstract we show that a variety of seemingly diverse concepts used to theoretically explaining the ekc have a common origin in two key preference and production elasticities we also prove that they jointly correspond to a unique underlying preference technology theoretical framework

voting for pollution policy the importance of income inequality and openness to trade abstract this paper analyzes how openness and the distribution of factor ownership interact to determine individual and aggregate demand for pollution policy analysis of voter preferences in autarky shows that an increased stake in either the dirty or the clean industry can induce an individual voter to prefer stricter environmental policy similarly the paper shows that poorer voters may be the greener voters within an electorate the model also reveals that the incidence of pollution policy depends upon a country s trade regime with consequences for the direction in which income inequality influences aggregate demand for pollution policy

economic growth and environmental degradation when preferences are non homothetic we study the dynamics of pollution in an economic growth model with non homothetic preferences we characterize the forces that may drive the evolution of the income pollution relationship along the development process in particular we disentangle the standard accumulation mechanism which determines the intertemporal allocation of pollution from a mechanism based on the non homotheticity of preferences which leads the intratemporal allocation of expenditure between consumption and pollution abatement to depend on income as the economy develops and aggregate income grows up the fraction of income devoted to abatement increases if the income elasticity of abatement is larger than unity in this case the pollution may decrease with income even when the elasticity of pollution with respect to abatement is smaller than the elasticity of pollution with respect to emissions we numerically illustrate how this demand based mechanism determines the dynamic relationship between pollution and aggregate income

on impatience economic growth and the environmental kuznets curve a dynamic analysis of resource management the paper presents a dynamic analysis of natural resource management and investigates some key factors that affect optimal management and resource conservation using a recursive specification of time preferences we show how endogenous discounting and impatience can affect the motivation for both capital investments and environmental preservation we examine the relationships between economic growth and environmental quality endogenous discounting provides new insights in the economic dynamics underlying the environmental kuznets curve by treating growth as endogenous we examine how externalities and economic growth interact with each other we investigate how economic development can contribute to an increased demand for environmental preservation as an important new result we also show how poverty can contribute to environmental degradation

status concern and the exploitation of common pool renewable resources we examine the impact of social status concern in a common pool renewable resource oligopoly a small number of players share access to a common pool resource and sell their production in a common market where they are oligopolists we depart from the mainstream literature on common pool resource oligopolies by considering that each player cares about her social status we allow for two channels to impact a player s welfare harvest and profits under the first channel a player has a bump in her utility when her harvest is larger than the average harvest of the rest of the players in this case we show that the presence of this channel exacerbates the tragedy of the commons under the second channel a player enjoys a bump in her utility if she manages to earn more profits than the average profits of the other players in this case we show that social status concern may temporarily alleviate the tragedy of the commons it results in a decrease of extraction over an interval of stock sizes

cleaning up while cleaning up pollution abatement interest groups and contingent trade policies this paper analyzes the political economy of environmental policy formation in a trading economy with established rules for administered protection we argue that the social costs associated with the adoption of an inefficient environmental regime are likely to be compounded by induced restrictions on trade when the effected industries are import competing the preferences of interest groups for alternative environmental regimes tend to be linked to the legal institutional setting in which trade policy is conducted under existing rules and practices in the area of administered protection there is reason to believe that interest group preferences for an inefficient approach to pollution control will be strengthened because the adoption of such a regime is more likely to lead to a concomitant increase in trade barriers

relief for the environment the importance of an increasingly unimportant industrial sector deindustrialization stagnant real incomes of production workers and increasing inequality are latter day features of many economies it is common to assume that such developments pressure policymakers to relax environmental standards however when heavily polluting industries become less important economically their political importance also tends to diminish consequently a regulator may increase the stringency of environmental policies like some other studies we find that declining industrial employment translates into stricter environmental standards in contrast to previous studies but consistent with our argument we find that greater income inequality is associated with policies that promote a cleaner environment jel q58 p16 j31 c23
