unequal vulnerability to climate change and the transmission of adverse effects through international trade in this paper we consider the unequal distribution of climate change damages in the world and we examine how the underlying costs can spread from a vulnerable to a non vulnerable country through international trade to focus on such indirect effects we treat this topic in a north south trade overlapping generations model in which the south is vulnerable to the damages entailed by global pollution while the north is not we show that the impact of climate change in the south can be a source of welfare loss for northern consumers in both the short and the long run in the long run an increase in the south s vulnerability can reduce the welfare in the north economy even in the case in which it improves its terms of trade in the short run the south s vulnerability can also represent a source of intergenerational inequity in the north therefore we emphasize the strong economic incentives for non vulnerable and a fortiori less vulnerable economies to reduce the climate change damages on more vulnerable countries

democracy financial openness and global carbon dioxide emissions heterogeneity across existing emission levels summary the determinants of co 2 emissions have attracted many researchers over the past few decades most of studies however ignore the possibility that effect of independent variables on co 2 emissions could vary throughout the co 2 emission distribution we address this issue by applying quantile regression methods we examine whether greater democracy and more financial openness consistently reduce emissions among the most and least emission nations our results show that the effect of democracy on co 2 emissions is heterogeneous across quantiles among the most emissions nations greater democracy appears to reduce emissions but more financial openness does not appear to reduce it

discount rates and credit markets theory and evidence from rural india three models of credit markets 1 the permanent income model 2 upward sloping credit supply to individual borrowers and 3 constrained credit due to imperfect enforcement are tested using credit market data and an experimental study of individuals discount rates in south india the permanent income model is rejected by both the discount rate and the credit market data the discount rate data are consistent with either of the other two models while the credit market data are consistent with a combination of these two models other explanations are found to be insufficient to explain the results of this study

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

trade openness and the environmental kuznets curve evidence from chinese cities this paper examines the impact of economic growth and trade openness on environment in 261 chinese cities over the period of 2004 2013 using recently developed continuously updated fully modified method which allows for both cross sectional dependence and endogeneity two types of pollutants industrial waste water and sulphur dioxide are investigated and three measures of openness are employed in the regression from the results we find that the environmental kuznets curve hypothesis holds not only for the whole china but also in different regions it is estimated that wastewater pollution increases with economic development until per capita gdp reaching the turning point of 42 991 48 828 yuan in constant 2002 price which varies depending on the specific measure of trade openness the turning point for sulphur dioxide is found to occur at a much lower income level around 9 588 10 663 yuan per capita gdp furthermore export is mostly found to be positively related with pollution and the impact of import is likely to be negative for both the whole china and across regions if the significance is identified in the estimation results

does trade liberalization increase national energy use abstract this paper utilises the theoretical principles of antweiler et al antweiler w b r copeland and m s taylor 2001 is free trade good for the environment american economic review 91 4 pp 877 908 to estimate empirically the linkages between trade liberalization and energy use focusing on scale technique and composition effects results suggest that trade will increase energy use for the mean country in the sample

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

is the troika bad for the environment an analysis of eu countries environmental performance in times of economic downturn and austerity memoranda abstract in this paper we examine the effect of the current economic crisis on the environmental performance of the eu countries by employing hierarchical linear multilevel hlm modeling we find that for the period 2000 2015 a drop in the national gdp a recession effect as well as endorsing a memorandum of understanding mou for receiving a imf eu ecb financial rescue package a troika effect have non significant to positive impacts on a number of national environmental quality and policy indicators over and above other economic political and governance predictors for eurozone and non eurozone countries alike nevertheless this changes drastically if we examine these two factors interaction experiencing a recession while being a recipient of a troika sponsored rescue package has detrimental effects on an eu country s national environment

a simple dynamic equilibrium model with adjustment costs abstract the equivalence of a perfect foresight equilibrium to a fisher competitive equilibrium and an optimal planning model is demonstrated for a model with an adjustment cost technology and a representative household adjustment costs lead to a non trivial dynamic optimization problem for the producer the results depend on the necessity of a transversality condition for the household producer and planner in their respective optimization problems the equivalence theorems are used to discuss conditions for multiple steady state equilibrium solutions and the corresponding stability properties

does trade liberalization lead to environmental burden shifting in the global economy abstract does trade liberalization lead to the outsourcing of pollution from industrialized countries to developing countries according to the pollution haven hypothesis international trade is a key channel through which richer countries can geographically dissociate consumption from production of goods we examine whether and how trade liberalization via preferential trade agreements ptas facilitates the shifting of consumption based environmental burdens from developed countries via imports to poorer countries via exports based on panel data analysis of 183 countries from 1987 to 2013 we find partial evidence for trade induced environmental burden shifting while we observe an increase in footprint exports from low income countries when these countries liberalize trade this is not matched by an increase in footprint imports of high income countries our results also show that environmental clauses in ptas and participation in international environmental agreements do not influence the relationship between trade liberalization and ecological footprint movements however domestic institutions have a significant effect on the trade induced distribution of environmental burdens these findings suggest that ptas as a policy tool for trade liberalization are per se unlikely to induce exploitation of low income countries natural capital by wealthier nations however they suggest that political incentives inherent to democratic institutions encourage environmental burden shifting

are rta agreements with environmental provisions reducing emissions article i nfo this paper investigates whether rtas with environmental provisions affect relative and absolute pollution levels in order to do so the determinants of carbon dioxide emissions convergence are estimated for a cross section of 182 countries over the period 1980 to 2008 a propensity score matching approach is com bined with difference in differences techniques to effectively isolate the effect of the regional trade agree ment rta variable the usual controls for scale composition and technique effects are added to the estimated model and the endogeneity of income and trade variables is modeled using instruments the main results indicate that the co2 emissions of the pairs of countries that belong to an rta with environmen tal provisions tend to converge and are lower in absolute terms whereas this is not the case for rtas without environmental provisions as regards specific agreements we find that emissions converge more rapidly for nafta than for eu 27 and euro med countries we find consistent evidence that only rtas with environ mental harmonization policies affect relative and absolute pollution levels

transversality conditions budget constraints and the determinacy of a perfect foresight equilibrium in a monetary growth model the purpose of this paper is to analyze the number of perfect foresight equilibria in a monetary model where the consumer s behavior and the firm s behavior are explicitly derived from an intertemporal optimization we show that the relevant transversality conditions reduce to the satisfaction of the intertemporal budget constraint of the consumer or alternatively of the government the assumption of a separable utility function enables us to characterize completely the perfect foresight equilibria their number is shown to depend both on the specification of the government s policy instruments and on the utility function

revisiting the environmental kuznets curve in malaysia the role of globalization in sustainable environment abstract the present study examines the presence of environmental kuznets curve ekc in malaysia by investigating impact of globalization including overall social economic and political on ecological footprint in the malaysian economy using quarterly data from 1970 to 2018 this research utilizes the quantile autoregressive distributed lag qardl method this approach is useful as it depicts the causality patterns through various quantiles of the globalization and environmental degradation by providing more comprehensive explanations of the over all dependence among the aforementioned variables almost ignored by the traditional approach for instance ardl and ols the outcomes of qardl showed that the error correction coefficient is significant with the anticipated negative sign for all quantiles this outcome provides evidence on the presence of considerable return to the long run equilibrium association between the factors of interest and environmental degradation overall the results recommended that overall globalization and economic globalization enhance the level of environmental degradation in the long run however political and social globalization help to reduce the level of environmental degradation in the long term moreover the results of qardl also confirmed the existence of inverted u shape curve in the malaysian economy in the shorter run period this study found a significant negative impact of overall globalization and political globalization on environmental degradation the results recommended that the malaysian government and policymakers need to give more attention to social and political globalization to achieve the goals of sustainable environment in the long run equilibrium

does economic integration damage or benefit the environment africa s experience abstract the leaders of african nations have committed to the establishment of the continental free trade area cfta over the coming years improved links among the african nations via increased intra regional trade have been considered as an essential mechanism to produce desired growth run overs and to support regional economic improvement however remarkable theoretical and empirical evidence has shown that increased trade might damage the environment and therefore may hinder the effort towards sustainable development and poverty reduction on the continent the present paper seeks to investigate and test the impact of intra africa trade using two measurements of environmental pollutants namely co2 and mp10 whilst integrating economic growth and energy consumption the study used a panel dataset regarding 46 african countries over the period 1990 2017 to carry out the empirical analysis the latest panel estimation techniques were employed more specifically and for the urbaneness purpose we employed a parametric technique which is dynamic ols and a non parametric approach which is fmols the results of both methods suggested that intra africa trade improved environmental quality on the continent in addition the results confirmed the presence of the environmental kuznets curve ekc hypothesis the findings also indicated that whilst the consumption of energy played a vital role in the deterioration of the environment its impact remained marginal overall the results implied that intra regional trade and the environment quality were mutually supportive in africa

trade openness and environmental quality international evidence we examine the relationship between trade openness and the environment in a cross country panel using the emission of particulate matter pm10 as the basic indicator of environmental quality the panel cointegration test results show a long run relationship between particulate matter emissions trade openness and economic growth we find that increased trade openness leads to environmental degradation for the global sample however the results differ according to the income of countries trade openness has a benign effect on the environment in high income countries but a harmful effect in middle and low income countries these results are generally robust to different measures of trade openness and environmental quality interestingly and significantly the results are consistent with the popular notion that rich countries dump their pollution on poor countries finally we find evidence of a feedback effect between trade openness and particulate matter emissions for the global sample as well as different income groups of countries

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

the environment left wing political orientation and ecological economics the objectives of this commentary are twofold the first is to examine the relationship between a party s position within the left right political spectrum and its stance on environmental issues as stated in party manifestos the second is to examine the relationship between individuals ideological orientation and pro environmental beliefs attitudes and self reported behavior equality distributional concerns and market skepticism are typically regarded as defining factors of left wing political orientation our results suggest that left wing parties and individuals are also more pro environmental than their right wing counterparts ecological economics similarly embraces sustainability efficient resource allocation and equitable distribution and is skeptical towards the ability of unregulated markets to achieve these objectives the hypothesis is put forward that ecological economics is more likely to be supported by left wing parties and individuals

macroeconomic uncertainty precautionary saving and the current account abstract the relationship between current account developments and changes in the macroeconomic environment is a key issue in open economy macroeconomics this paper extends the standard intertemporal model of the current account to incorporate the effects of macroeconomic uncertainty on external saving behavior it is shown that the greater the uncertainty in national cash flow defined as output less investment less government consumption the greater will be the incentive for precautionary saving and ceteris paribus the larger the current account surplus empirical support for the model is found using post war quarterly data for the united states japan and the united kingdom as well as a long time series 1919 1990 for the united states

present bias quasi hyperbolic discounting and fixed costs in this paper we elicit preferences for money time pairs via experimental techniques we estimate a general specification of discounting that nests exponential and hyperbolic discounting as well as various forms of present bias including quasi hyperbolic discounting our experimental data do not appear peculiar in any dimension in particular we find clear evidence for present bias as most of the previous literature however no evidence for quasi hyperbolic discounting is found and the data strongly favor instead a specification with a small present bias in the form of a fixed cost of the order of 4 on average across subjects with such a fixed cost the curvature of discounting is imprecisely estimated and exponential discounting is hardly rejected in this specification the present bias tends to vanish for economically relevant monetary rewards

trade in environmental goods evidences from an analysis using elasticities of trade costs negotiations on the liberalization of environmental goods egs and services within the wto doha round mandated in november 2001 are facing specific challenges conflicting interests and differing perceptions of the benefits of increased trade in egs were reflected in different approaches proposed for determining egs using import data of 34 organisation for economic co operation and development oecd member countries and from a sample of 167 countries from 1995 to 2012 we discuss the trade effect of reducing barriers on egs we analyze the lists of egs proposed by the asia pacific economic cooperation and oecd using a translog gravity model we found that removing tariff barriers for egs will have a modest impact because for the biggest importers and exporters elasticities of trade costs are very low while for most trading relationships they are very high making it difficult for exporters to maintain their markets overall our results suggest that because of their substantial effect on international trade future negotiations on egs should also address the issues of standards and nontariff barriers

investigation of the environmental kuznets curve for carbon emissions in malaysia do foreign direct investment and trade matter abstract environmental degradation has become a central issue of discussion among the economists and environmentalists in view of malaysia s position as one of the main contributors to co2 emissions in asia and its status as a fast growing economy it is vital therefore to conduct a study to identify the relationship between economic growth and co2 emissions for malaysia this study attempts to examine empirically the environmental kuznets curve hypothesis for malaysia in the presence of foreign direct investment and trade openness both in the short and long run for the period 1970 to 2008 the bounds testing approach and granger causality methodology are applied to test the interrelationships of the variables the results of our study indicate that the inverted u shaped relationship does exist between economic growth and co2 emission in both the short and long run for malaysia after controlling for two additional explanatory variables namely fdi and trade importantly the results of the study also provide some crucial policy recommendations to the policy makers

does trade openness improve environmental quality the literature on trade openness economic development and the environment is largely inconclusive about the environmental consequences of trade this study treats trade and income as endogenous and estimates the overall impact of trade openness on environmental quality using the instrumental variables technique we find that whether or not trade has a beneficial effect on the environment varies depending on the pollutant and the country trade is found to benefit the environment in oecd countries it has detrimental effects however on sulfur dioxide so2 and carbon dioxide co2 emissions in non oecd countries although it does lower biochemical oxygen demand bod emissions in these countries we also find the impact is large in the long term after the dynamic adjustment process although it is small in the short term

trade openness carbon emissions nexus the importance of turning points of trade openness for country panels abstract this paper explores the relationship between trade openness and co 2 emissions by incorporating economic growth as an additional and potential determinant of this relationship for three groups of 105 high middle and low income countries we apply the pedroni 1999 and westerlund 2007 panel cointegration tests and find that the three variables are cointegrated in the long run trade openness impedes environmental quality for the global high income middle and low income panels but the impact varies in these diverse groups of countries the panel vecm causality results highlight a feedback effect between trade openness and carbon emissions at the global level and the middle income countries but trade openness granger causes co 2 emissions for the high income and low income countries policy implications are also provided

the carbon footprint of greek households 1995 2012 abstract the goal of this paper is twofold i to investigate the carbon footprint of greek households throughout the period 1995 2012 in order to identify the main socio economic factors that affect ghg emissions and ii to evaluate the effectiveness of the implemented policies to tackle climate change in this a consumption based emissions inventory approach is applied the analysis is based on an environmentally extended input output model including direct co2 emissions from households indirect co2 emissions from electricity consumption and indirect co2 emissions from energy used in the production of goods and services purchased by households domestic or imported statistical analysis and appropriate regression models were developed in order to identify the main factors influencing the carbon footprint of greek households the results indicate that the observed trends during the period 1995 2008 can be attributed to the effect of high economic growth this trend is partially counterbalanced by favorable weather conditions and the implementation of greenhouse mitigation policies and measures mainly in the supply side since 2008 the shrinking household income is the dominant driver in addition the effectiveness of energy conservation policies and measures in place is rather low while the effect of imports is limited

energy intensity developments in 40 major economies structural change or technology improvement this study analyzes energy intensity trends and drivers in 40 major economies using the wiod database a novel harmonized and consistent dataset of input output table time series accompanied by environmental satellite data we use logarithmic mean divisia index decomposition to 1 study trends in global energy intensity between 1995 and 2007 2 attribute efficiency changes to either changes in technology or changes in the structure of the economy and 3 highlight sectoral and regional differences we first show that heterogeneity within each sector across countries is high these general trends within the sectors are dominated by large economies first and foremost the united states in most cases heterogeneity is lower within each country across the different sectors regarding changes of energy intensity at the country level improvements between 1995 and 2007 are largely attributable to technological change while structural change is less important in most countries notable exceptions are japan the united states australia taiwan mexico and brazil where a change in the industry mix was the main driver behind the observed energy intensity reduction

participation in gvcs and co2 emissions abstract this paper attempts to explore the determinants of co2 emissions in the context of international trade while there exist studies that examine the roles of horizontal specialization and inter industry trade transactions little previous research attention has been paid to the roles of vertical specialization and intra industry trade transactions in affecting co2 emissions to fill the knowledge gap this study uses the panel data of 62 countries and regions for the period of 1995 2011 to estimate the effect of participation in global value chains gvcs on per capita co2 emissions major findings include 1 the relationship between participation degrees in gvcs and per capita co2 emissions is found to be inversely u shaped at the aggregate economy level and for most individual industries 2 per capita gdp shows an n shaped relationship with per capita co2 emissions and 3 benign drivers of co2 emissions include r d energy conservation and population control it can be concluded that countries with low gdp or gvc participation degrees are expected to experience worsening co2 emissions in the short or even medium run this trend however can be moderated or even reversed with more r d investments

trade the pollution haven hypothesis and the environmental kuznets curve examining the linkages abstract this paper examines the extent to which the ekc inverted u relationship can be explained by trade and specifically the migration or displacement of dirty industries from the developed regions to the developing regions the pollution haven hypothesis phh using detailed data on north south trade flows for pollution intensive products the evidence for the phh is assessed emissions of 10 air and water pollutants are then estimated controlling for trade openness structural change and dirty north south trade flows evidence of pollution haven effects is found although such effects do not appear to be widespread and appear to be relatively small compared to the roles played other explanatory variables

are left wing party strength and corporatism good for the environment evidence from panel analysis of air pollution in oecd countries abstract the effect of left wing party strength and corporatism on air pollution levels in up to 21 oecd countries over the period 1980 or 1990 1999 is tested with both fixed effects and random effects estimators controlling for scale composition technique as well as aggregate time effects robust evidence is found that parliamentary green left libertarian party strength is associated with lower pollution levels the rise of ecologically oriented parties has thus had a real impact on air pollution levels traditional left wing party strength is possibly also associated with lower pollution levels but the evidence is less consistent and robust combined left wing party strength in government is possibly associated with higher pollution levels but this result is also far from robust and is practically small no evidence is found for a consistent systematic impact of corporatism on pollution levels

domestic and international influences on green taxation economists have made a strong case for the relative efficiency of market based mechanisms for environmental regulation such as cap and trade and green taxes yet the spread of these forms has been limited and traditional command and control regulation still predominates the authors explain geographical and temporal variation in green tax burdens by considering their domestic and international determinants modeling international influences using spatial lags hypotheses are tested using panel data on organisation for economic co operation and development member states from 1995 to 2004 at the domestic level the authors show that green tax burdens are influenced by the left right and environmental positions of legislative medians and the power of the energy producing sector among other factors the authors also show that ideas about policy diffuse through international networks generated by trade and environmental intergovernmental organizations but they do not find compelling evidence for intern

macroeconomic volatility and welfare in developing countries macroeconomic volatility and welfare in developing countries an introduction norman v loayza romain ranciere luis serven and jaume ventura macroeconomic volatility both a source and a reflection of underdevelopment is a fundamental concern for developing countries this article provides a brief overview of the recent literature on macroeconomic volatility in developing countries highlighting its causes consequences and possible remedies to reduce domestic policy induced macroeconomic volatility by controlling the level and variability of fiscal expenditures by keeping inflation low and stable and by avoiding price rigidity including that of the exchange rate which eventually leads to drastic adjustments the ability to conduct countercyclical fiscal policies is crucial and it depends largely on the ability of the authorities to reduce public indebtedness to internationally acceptable levels establish a record of saving in good times to provide for bad times and develop credibility tha

environmental policy design innovation and efficiency gains in electricity generation this paper explores the relationship between environmental regulation innovation and competitiveness drawing upon a unique dataset on environmental regulations directed at combustion plants a global dataset of power plants and a global dataset of environmental patents the analysis is conducted in two stages first a nonparametric frontier analysis is implemented to estimate efficiency scores including a measure of technological innovation based on patent stocks second econometric methods are applied to analyse the role of policy stringency and policy design on efficiency our estimation sample covers thermal power plant sectors in 20 countries from 1990 to 2009 the results show that the stringency of environmental regulations is a significant determinant of productive efficiency with respect to pollutant emissions as well as fuel use however these effects turn negative once the level of stringency leaps over a certain threshold in addition the paper concludes that the positive effect of regulatory stringency can be diminished by a negative effect of regulatory differentiation with measures which are differentiated across plant size and age having negative consequences and these effects are increasing over time this finding is important given the prevalence of size and vintage differentiated policies in many countries finally it is found that integrated approaches to environmental innovation are more likely to bring about efficiency improvements than end of pipe technologies

tariffs and environmental taxes in the presence of environmental r d it is generally held that trade liberalization results in less stringent environmental regulations which suggests that policies regulating trade and the environment are positively correlated this paper examines whether this monotonic relationship still holds true when pollution reducing environmental research and development erd ii an environmental tax instrument only and iii both regulatory instruments to correct for distortions relating to trade and the environment we find that if it is not possible to abate pollution completely through er d then the monotonic relationship between tariffs and environmental taxes is sustained however if it is possible to fully abate pollution through er d then the optimal tariff environmental tax may not increase monotonically with taxes tariffs when both environmental taxes and tariffs are employed these two policies may be strategic substitutes a positive relationship between tariffs and environmental taxes may not be applicable

is economic volatility detrimental to global sustainability in a dynamic panel data model allowing for error cross section dependence output volatility is found to impede sustainable development through a financial development channel liquidity liability ratio output volatility exerts a significant effect on depletion of natural resources a key component of sustainability low income countries low energy intensity countries and low trade share countries tend to be especially vulnerable to macroeconomic volatility and shocks the findings highlight the interaction between global financial markets and the wider economy as a key factor influencing sustainable development with important implications for macroeconomic and environmental policies in an integrated global green economy

measuring the effect of economic growth on countries environmental efficiency a conditional directional distance function approach using a recently developed probabilistic approach of a conditional directional distance function we measure the effect of economic growth on countries environmental efficiency in carbon dioxide emissions for a sample of 99 countries over the period of 1980 2010 our approach directly accounts for the exogenous factors influencing countries environmental production therefore we do not impose the separability condition on the estimated environmental efficiencies when examining the entire sample as well as the sample of developed countries our results reveal an inverted u shaped relationship between countries gdp per capita and environmental efficiency however when examining the relationship for the sample of developing countries the results reveal an n shaped form moreover our results show that countries ratifying the kyoto protocol tend to have higher efficiency scores implying that their mitigation activity is less costly

macroeconomic volatility and welfare in developing countries an introduction macroeconomic volatility both a source and a reflection of underdevelopment is a fundamental concern for developing countries their high aggregate instability results from a combination of large external shocks volatile macroeconomic policies microeconomic rigidities and weak institutions volatility entails a direct welfare cost for risk averse individuals as well as an indirect one through its adverse effect on income growth and development this article provides a brief overview of the recent literature on macroeconomic volatility in developing countries highlighting its causes consequences and possible remedies it then introduces the contributions of a recent conference on the subject sponsored by the world bank and pompeu fabra university barcelona

crises volatility and growth how do volatility and liquidity crises affect growth when credit is constrained a bias toward short term debt can arise in financing long term investments generating maturity mismatches and leading potentially to liquidity crises the frequency of liquidity crises and the volatility of growth are found to have independent negative effects on growth financial development however dampens the growth cost of volatility but only in the case of normal volatility the growth cost of volatility therefore depends critically on the composition of normal and abnormal volatility the latter being more costly for growth

temporal change of china s pollution terms of trade and its determinants abstract based on the world input output database wiod this study employed a revised pollution terms of trade ptt indicator to investigate the temporal change of china s environmental cost relative to its economic gains from international trade from 1995 to 2009 the results show that china has ptt larger than 1 indicating that china emits more emissions to obtain each unit of value added from exports than its trade partners over the period china s ptt first decreased from 1995 to 2001 and then increased from 2001 to 2009 the further decompositions show that improving technology is the leading driving force to decrease ptt while the change in global trade pattern is the leading force increasing ptt especially after 2001 we further decomposed the temporal change of china s ptt by income group of the trading partners the results show that the change in the global trade pattern is the crucial driving force behind the different changes of ptt by income group

the environmental consequences of trade evidence from subnational trade flows abstract the debate over the environmental consequences of free trade is not only quite heated but also entails significant policy ramifications recently cross sectional analysis at the country level has made use of exogenous determinants of trade to identify the causal effect of trade on the environment finding moderate evidence of a beneficial impact of expanded trade on environmental quality given the stakes involved we revisit this finding using subnational data on trade flows across us states and several measures of pollution not only does the analysis shed further light on the debate at the international level but also addresses a heretofore unexamined question does greater inter regional commerce at the subnational level harm the environment our findings are striking providing further evidence against a negative environmental impact of trade for the majority of measures analyzed however several sources of heterogeneity arise that are noteworthy

discounting by intervals a generalized model of intertemporal choice according to most models of intertemporal choice an agent s discount rate is a function of how far the outcomes are removed from the present and nothing else this view has been challenged by recent studies which show that discount rates tend to be higher the closer the outcomes are to one another subadditive discounting and that this can give rise to intransitive intertemporal choice we develop and test a generalized model of intertemporal choice the discounting by intervals dbi model according to which the discount rate is a function of both how far outcomes are removed from the present and how far the outcomes are removed from one another the model addresses past challenges to other models most of which it includes as special cases as well as the new challenges presented in this paper our studies show that when the interval between outcomes is very short discount rate tends to increase with interval length superadditive discounting in the discussion we place our model and evidence in a broader theoretical context

are we consuming too much this paper articulates and applies frameworks for examining whether consumption is excessive we consider two criteria for the possible excessiveness or insufficiency of current consumption one is an intertemporal utility maximization criterion actual current consumption is deemed excessive if it is higher than the level of current consumption on the consumption path that maximizes the present discounted value of utility the other is a sustainability criterion which requires that current consumption be consistent with non declining living standards over time we extend previous theoretical approaches by offering a formula for the sustainability criterion that accounts for population growth and technological change in applying this formula we find that some poor regions of the world are failing to meet the sustainability criterion in these regions genuine wealth per capita is falling as investments in human and manufactured capital are not sufficient to offset the depletion of natural capital

the role of education in the environmental kuznets curve evidence from australian data abstract this paper is based on the underlying idea that the use of energy resources in a society significantly depends on their level of education then it is hypothesized that education might directly affect environmental quality by worsening it at early stages and improving it once education expands from its certain level thus we pursue an extension of the standard environmental kuznets curve by including an indicator of the evolution of citizens education this empirical strategy might avoid bias on income coefficients and in turn assess the value of education as environmental policy an application for australia is given to illustrate this possibility by using higher education data for a large time span 1950 2014 empirical results suggest that in most of the studied period expansion in education rate has increasingly compensated the rise of per capita co 2 emissions stemming from the economic growth moreover only in recent years both per capita income and education expansion have been proved to reduce emissions however provided that income growth is difficult to manage it would be worth considering the possibility of promoting education in order to achieve environmental objectives

why cooperate public goods economic power and the montreal protocol this paper develops a correlated probit model to describe dichotomous choices that may contain a public goods component or some other forms of interdependency the key contribution of the paper is to formulate tests for interdependent behavior among agents in particular we examine the decisions by nations whether or not to ratify the montreal protocol on substances that deplete the ozone layer specifically we reject free riding as a motive for not ratifying the protocol and we find little evidence that individual nations were influenced by the behavior of their largest trading partners hence the data suggest that with respect to the montreal protocol most nations acted without regard for the actions of other nations

the participation decision versus the level of participation in an environmental treaty a spatial probit analysis abstract this paper represents treaty participation as a two stage game for which nations first decide whether or not to participate and then they choose their level of participation the resulting subgame perfect equilibrium is used to derive a reduced form equation for estimating and separating the influences of the variables at the two decision stages this spatial probit equation forms the basis for a full information maximum likelihood estimator that accounts for the simultaneity bias associated with public good spillins at both stages when the procedure is applied to the helsinki protocol we find that the strategic influence of a variable may drastically differ depending upon which stage is scrutinized

carbon dioxide emissions and international trade at the turn of the millennium we present a new dataset of geographical production final embodied production and consumption based carbon dioxide emission inventories covering 78 regions and 55 sectors from 1997 to 2011 we extend previous work both in terms of time span and in bridging from geographical to embodied production and ultimately to consumption we analyse the recent evolution of emissions the development of carbon efficiency of the global economy and the role of international trade as the distribution of responsibility for emissions across countries is key to the adoption and implementation of international environmental agreements and regulations the final production and consumption based inventories developed here provide a valuable extension to more traditional geographical production based criteria

effects of political institutions on air quality we empirically test existing theories on the provision of public goods in particular air quality using data on sulfur dioxide so2 concentrations from the global environment monitoring projects for 107 cities in 42 countries from 1971 to 1996 the results are as follows first we provide additional support for the claim that the degree of democracy has an independent positive effect on air quality second we find that among democracies presidential systems are more conducive to air quality than parliamentary ones third in testing competing claims about the effect of interest groups on public goods provision in democracies we establish that labor union strength contributes to lower environmental quality whereas the strength of green parties has the opposite effect

estimating individual discount rates in denmark a field experiment we estimate individual discount rates with respect to time streams of money using controlled laboratory experiments these discount rates are elicited by means of field experiments involving real monetary rewards the experiments were carried out across denmark using a representative sample of 268 people between 19 and 75 years of age individual discount rates are estimated for various households differentiated by socio demographic characteristics such as income and age our conclusions are that discount rates are constant over the 12 month to 3 year horizons used in these experiments and that discount rates vary substantially with respect to several socio demographic variables hence we conclude that it would be reasonable to assume constant discount rates for specific household types but not the same rates across all households

reversal and magnitude effects in long term time preferences results from a field experiment we use a multiple price list approach with real payments to elicit long term time preferences on a sample of french farmers elicited individual discount rates vary with the time delay which supports the existence of a reversal effect in long term time preferences and increase with rewards which contradicts the usual magnitude effect finding

the equivalence of a fisher competitive equilibrium and a perfect foresight competitive equilibrium in a multi sectoral model of capital accumulation the purpose of this paper is to demonstrate the importance of the transversality condition for an intertemporal competitive equilibrium to be equivalent to a fisher competitive equilibrium the transversality condition also emerges to show the optimality of either equilibrium process 2 another concern of this paper is the importance of assumptions about individual savings and expectations 3 the models of this paper derive an agent s savings decision from an explicit intertemporal optimization model under conditions of perfect capital markets and long run perfect foresight the perfect foresight assumption means that paths of prices dividends and rental rates expected to occur at any future time are realized in an intertemporal equilibrium referred to as a perfect foresight competitive equilibrium this paper provides a demonstration that a perfect foresight competitive equilibrium is equivalent to a fisher competitive equilibrium the abstract economy under consideration consists of a representative consumer and a production or investment opportunity sector there are n capital goods used for investment goods and one pure consumption good produced under the condition of nojoint production capital goods are not consumed nor do they depreciate

estimating time preferences from convex budgets experimentally elicited discount rates are frequently higher than what seems reasonable for economic decision making such high rates are often attributed to present biased discounting a well known bias of standard measurements is the assumption of linear consumption utility attempting to correct this bias using measures of risk aversion to identify concavity researchers find reasonable discounting but at the cost of exceptionally high utility function curvature we present a new methodology for identifying time preferences both discounting and curvature from simple allocation decisions we find reasonable levels of both discounting and curvature and surprisingly dynamically consistent time preferences jel c91 d12 d81 understanding and estimating time preferences is obviously of great importance to economists marketers and policy makers consumers decide how much to invest in savings education real estate and life insurance how much to diet exercise and smoke whether to marry when to have children and what to leave in their wills while there has been substantial research estimating time preferences using aggregate consumption data 1 the bulk of the effort has occurred in laboratory environments 2 among the many laboratory techniques employed recent studies have favored multiple price lists mpl with monetary payments 3 with mpls individuals are asked multiple times to choose between smaller payment amounts closer to the present and larger amounts further into the future the interest rate increases monotonically in a price list such that the point where an individual switches from preferring sooner payments to later payments carries interval

volatility and development why is gdp growth so much more volatile in poor countries than in rich ones we identify four possible reasons i poor countries specialize in more volatile sectors ii poor countries specialize in fewer sectors iii poor countries experience more frequent and more severe aggregate shocks e g from macroeconomic policy and iv poor countries macroeconomic fluctuations are more highly correlated with the shocks of the sectors they specialize in we show how to decompose volatility into these four sources quantify their contribution to aggregate volatility and study how they relate to the stage of development we document the following regularities first as countries develop their productive structure moves from more volatile to less volatile sectors second the level of specialization declines with development at early stages and slowly increases at later stages of development third the volatility of country specific macroeconomic shocks falls with development fourth the covariance between sector specific and country specific shocks does not vary systematically with the level of development we argue that many theories linking volatility and development are not consistent with these findings and suggest new directions for future theoretical work

sources of emission reductions market and policy stringency effects abstract international trade and economic development affect air emissions previous studies have decomposed their effects into scale composition and technique effects while the scale and composition effects occur through market responses the technique effect is a policy stringency influence through the mix of environmental policies this study analyzes whether the market or policy stringency effects are more prominent previous studies have been unable to adequately separate the market and policy stringency effects to independently measure the technique effect we use two indicators of policy stringency i e shadow prices of energy and industrial energy prices these policy stringency measures are treated as endogenous the effects on six types of air emissions are estimated utilizing a sector specific international panel dataset that includes newly industrialized and former transition economies the empirical results show that the major source of emissions reductions is the policy stringency effect through carbon related policies pollution offshoring to countries with weaker carbon related regulation has a minor role in the reduction of air emissions

the personal discount rate evidence from military downsizing programs the military drawdown program of the early 1990s provides an opportunity to obtain estimates of personal discount rates based on large numbers of people making real choices involving large sums the program offered over 65 000 separatees the choice between an annuity and a lump sum payment despite break even discount rates exceeding 17 percent most of the separatees selected the lump sum saving taxpayers 1 7 billion in separation costs estimates of discount rates range from 0 to over 30 percent and vary with education age race sex number of dependents ability test score and the size of payment

cross country evidence on the link between volatility and growth this paper presents empirical evidence against the standard dichotomy in macroeconomics that separates growth from the volatility of economic fluctuations in a sample of ninety two countries as well as a sample of oecd countries the authors find that countries with higher volatility have lower growth the addition of standard control variables strengthens the negative relationship the authors also find that government spending induced volatility is negatively associated with growth even after controlling for both time and country fixed effects copyright 1995 by american economic association
