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

is democracy good for the environment quasi experimental evidence from regime transitions this paper tests the hypothesis that democratisation is conducive to less environmental depletion due to human activity using interrupted time series design for a panel of 47 transition countries and two indexes of pollution co 2 emissions and pm10 concentrations i find that democracies and dictatorships have two different targets of environmental quality with those of democracies higher than those of dictatorships income inequality may as well alter this targets but with opposite effects in the two different regimes

does income inequality harm the environment empirical evidence from the united states abstract this study revisits the growth inequality environment nexus in the context of country specific time series data the short and long run effects of income inequality economic growth and energy consumption on co2 emissions in the u s are examined using the autoregressive distributed lag ardl approach we find that more equitable distribution of income in the u s results in better environmental quality in the short and long run it is also found that in both the short and long run economic growth has a beneficial effect on environmental quality whereas energy consumption has a detrimental effect on the environment

the renewable energy growth and environmental kuznets curve in turkey an ardl approach abstract this study examines the potential of renewable energy sources in reducing the impact of ghg emissions in turkey using autoregressive distributed lag ardl approach the relationship between co 2 emissions electricity generated using renewables and gdp in turkey has been investigated during 1961 2010 moreover the validity of environmental kuznets curve ekc hypothesis has been tested model results show that the coefficient of electricity production from renewable sources hydro power excluded with respect to co 2 emissions is negative and significant in the long run although this effect is positive and statistically significant in the short run since the ecm term is 0 82 it becomes negative around 1 year this means that renewable electricity production will contribute to environmental enhancement with a one year lag our results also suggest a u shaped ekc relationship between per capita ghgs and income estimations from a long run regression show that although the peak point of gdp per capita has been calculated to be 9920 us dollars this turning point was outside of the observed sample period therefore ghg emissions start to decrease with an increase in per capita gdp in the following years model research implies the potential and the importance of renewable energy sources in controlling of emissions in turkey

measuring the liquidity effect this paper measures the effect on the federal funds rate of an open market operation the paper deals with simultaneous equations bias by developing a proxy for the errors the federal reserve makes in forecasting the extent to which treasury operations will add or drain reserves available to private banks these errors induce fluctuations in bank reserves which have measurable consequences for the federal funds rate the paper estimates that a reduction in nonborrowed reserves of 30 million if sustained for an entire fourteen day reserve maintenance period will cause the federal funds rate to rise by ten basis points copyright 1997 by american economic association

precision of dichotomous choice contingent valuation welfare measures some simulation results the purpose of this research is to examine the roles of individuals heterogeneous economic factors and model misspecification in dichotomous choice contingent valuation welfare measurement willingness to pay for an improvement of environmental quality is studied simulation results indicate that the precision of welfare estimates increases with individuals income levels and decreases with the price of the quality related good the dependence of the consumption of the quality related good on the environmental quality also affects the reliability of welfare estimates

an econometric study of co2 emissions energy consumption income and foreign trade in turkey abstract this study attempts to empirically examine the dynamic causal relationships between carbon emissions energy consumption income and foreign trade in the case of turkey using the time series data for the period 1960 2005 this research tests the interrelationship between the variables using the bounds testing to cointegration procedure the bounds test results indicate that there exist two forms of long run relationships between the variables in the case of first form of long run relationship carbon emissions are determined by energy consumption income and foreign trade in the case of second long run relationship income is determined by carbon emissions energy consumption and foreign trade an augmented form of granger causality analysis is conducted amongst the variables the long run relationship of co2 emissions energy consumption income and foreign trade equation is also checked for the parameter stability the empirical results suggest that income is the most significant variable in explaining the carbon emissions in turkey which is followed by energy consumption and foreign trade moreover there exists a stable carbon emissions function the results also provide important policy recommendations

political and economic inequality and the environment abstract this paper analyzes and tests the hypothesis that political and economic equality result in lower levels of environmental degradation based on formal statements of the argument put forward by boyce r 1994 ecological economics 11 169 178 i show that equality may or may not be necessary to minimize degradation under some plausible conditions greater inequality may even be conducive to lower degradation actual results depend primarily on the intersection between the distribution of preferences across groups and the institutional rules two cross national empirical tests tend to support the contention that distributional issues do not systematically explain variations in environmental quality the results reinforce the conclusion that assumptions about the structure of preferences and workings of social choice institutions ignore complex interactions which influence the relationship between degradation and equality

income inequality and the environment aggregation bias in environmental kuznets curves abstract the environmental kuznets curve assumes an inverted u shaped relation between environmental damage and per capita income recently it has been argued in the literature that in addition to income levels the inequality in the distribution of power and income is positively related to environmental degradation we provide an additional argument based on simple aggregation for including a measure of income dispersion in empirical analyses when the relationship between environmental damage and household income is concave e g resembles an environmental kuznets curve then income inequality is negatively related to total environmental damage results from an empirical analysis of cross national variation indicate that the aggregation effect can run counter to and outweigh the political economy effect for some environmental indicators

smooth breaks and non linear mean reversion post bretton woods real exchange rates the recent literature on purchasing power parity ppp has emphasized the role of two phenomena that may lead to the rejection of the ppp hypothesis structural breaks and non linear adjustment induced by transaction costs these two hypotheses are analyzed separately in the literature we develop tests for unit roots that account jointly for structural breaks and non linear adjustment structural breaks are modeled by means of a fourier function that allows for infrequent smooth temporary mean changes and is hence compatible with long run ppp nonlinear adjustment is modeled by means of an estar model our tests present good finite sample properties the tests are applied to a set of 15 oecd countries rers and are able to reject the null of a unit root in 14 cases the breaks are usually associated with the great appreciation and later depreciation of the dollar in the 1980s and the estar adjustment appears to play an important role

income inequality in the united states 1913 1998 this paper presents new homogeneous series on top shares of income and wages from 1913 to 1998 in the united states using individual tax returns data top income and wages shares display a u shaped pattern over the century our series suggest that the large shocks that capital owners experienced during the great depression and world war ii have had a permanent effect on top capital incomes we argue that steep progressive income and estate taxation may have prevented large fortunes from fully recovering from these shocks top wage shares were flat before world war ii dropped precipitously during the war and did not start to recover before the late 1960s but are now higher than before world war ii as a result the working rich have replaced the rentiers at the top of the income distribution

inequality as a cause of environmental degradation abstract this paper advances two hypotheses first the extent of an environmentally degrading economic activity is a function of the balance of power between the winners who derive net benefits from the activity and the losers who bear net costs second greater inequalities of power and wealth lead all else equal to more environmental degradation

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

the liquidity effect in the federal funds market evidence at the monthly frequency in this paper we argue that much of the research into the link between money and interest rates suffers from misspecification the measure of money and the measure of interest rates are not always well matched in examining the transmission of monetary policy we show that using an appropriate measure of money federal reserve balances and the appropriate interest rate the federal funds rate a clear liquidity effect exists furthermore we explain how a lack of a clear institutional understanding may have contributed to the finding of a liquidity puzzle in the past

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

conducting monetary policy at very low short term interest rates can monetary policy committees accustomed to describing their plans and actions in terms of the level of a short term nominal interest rate find effective means of conducting and communicating their policies when that rate is zero or close to zero the very low levels of interest rates in japan switzerland and the united states in recent years have stimulated much interesting research on this question and have led some central banks to make changes in their operating procedures and communications strategies in this paper we will give a brief overview of current thinking on the conduct of monetary policy when short term interest rates are very low or even zero monetary policy works for the most part by influencing the prices and yields of financial assets which in turn affect economic decisions and thus the evolution of the economy when the short term policy rate is at or near zero the conventional means of effecting monetary ease lowering the target for the policy rate is no longer feasible however it would be a mistake to think that monetary policy was impotent we discuss three strategies for stimulating the economy at an unchanged level of the policy rate these involve i providing assurance to investors that short rates will be kept lower in the future than they currently expect ii changing the relative supplies of securities in the marketplace by altering the composition of the central bank s balance sheet and iii increasing the size of the central bank s balance sheet beyond the level needed to set the short term policy rate at zero quantitative easing we also discuss the costs and benefits of very low interest rates an issue that bears on the question of whether the central bank should take the policy rate all the way to zero before undertaking alternative policies

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

differences between willingness to pay estimates from open ended and discrete choice contingent valuation methods the effects of heteroscedasticity most comparative studies find that the discrete choice contingent valuation method dc cvm yields higher willingness to pay wtp estimates than the open ended oe format in this paper we discuss and test several hypotheses to explain why wtp estimates from oe and dc cvm questions differ we find that wtp estimates from discrete choice data are very sensitive to assumptions made about the random utility in particular violation of the homoscedasticity assumption may lead to biased wtp estimates if the error terms are correlated with the cost this violation was a main source of difference in wtp estimates in our studies

mechanisms explaining the impact of economic inequality on environmental deterioration abstract rising economic inequality often considered intrinsically harmful is increasingly being viewed as having a number of secondary impacts as well including impacts on health and economic growth the ongoing nature of today s environmental crisis also raises questions about inequality s role in environmental deterioration despite the large number of papers that have been written on this topic no theoretical or empirical consensus presently exists firstly our article identifies that authors conclusions in this area depend on their hypotheses regarding 1 the relationship between individual income and individual environmental pressure 2 the impact of inequality on the social norms that influence individual environmental pressure 3 the interests that social groups have in degrading or protecting the environment 4 how these interests play out in terms of political demands and 5 how these political demands translate into political decisions secondly the study shows that despite enabling a general test of the causal relationship between inequality and the environment the empirical methods utilised do not account for the full range of theoretical mechanisms in play hence the suggestion that a research programme be launched to conduct empirical studies of the five aforementioned hypotheses by applying a recursive approach

income inequality and carbon dioxide emissions the case of chinese urban households abstract this paper draws on chinese survey data to investigate variations in carbon dioxide emissions across households with different income levels rich households generate more emissions per capita than poor households via both their direct energy consumption and their higher expenditure on goods and services that use energy as an intermediate input an econometric analysis confirms a positive relationship between emissions and income and establishes a slightly increasing marginal propensity to emit mpe over the relevant income range the redistribution of income from rich to poor households is therefore shown to reduce aggregate household emissions suggesting that the twin pursuits of reducing inequality and emissions can be achieved in tandem

testing for misspecification in the referendum contingent valuation approach binary choice models are frequently used in the analysis of referendum contingent valuation data because omitted regressors heteroskedasticity and distribution asymmetry in these models result in inconsistent parameter estimates it is important that misspecification tests be undertaken in this article conditional moment tests for these problems are presented and applied to data from two referendum contingent valuation studies results show that some models have misspecification problems and that these problems affect the estimation of welfare measures

the federal reserve s balance sheet and overnight interest rates empirical modeling of exit strategies abstract this paper provides a comprehensive study of the interplay between the federal reserve s balance sheet and overnight interest rates we model both the supply of and the demand for excess reserves treating outright securities holdings of the federal reserve as a policy tool we estimate the effects of unconventional monetary policy on overnight funding rates further we offer the first empirical assessment of the fomc s principles of the exit strategy assuming a path for removing monetary policy accommodation that is consistent with the fomc s exit principles we project that the federal funds rate increases to 70 basis points by 2016 settling in a corridor bracketed by the discount rate and the interest rate on excess reserves as excess reserves of depository institutions decline to near zero

the liquidity effect for open market operations abstract the liquidity effect is the negative relationship between the supply of federal funds and the overnight federal funds rate deviations of the federal funds rate from its target can be interpreted as demand innovations for federal funds permanent adjustments to demand are modeled as an unobserved component and estimated using the kalman filter to identify liquidity effects the demand based approach for identifying the liquidity effect contrasts previous work which concentrates on errors forecasting the supply of federal funds this paper finds a liquidity effect several times larger than that from previous studies indicating the market for federal funds is less liquid than previously thought the effect of a 1 billion increase in open market operations over a 1 week period is a decrease of the federal funds rate by about 12 basis points

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 preliminary analysis of texas ranchers willingness to participate in a brush control cost sharing program to improve off site water yields abstract brush cover of 30 is estimated to be economically optimal for ranches on the edwards plateau texas this contrasts with a regional objective to increase off site water yield which is maximized if brush cover is removed survey research was conducted to assess ranchers willingness to enter a 10 year easement contract to clear brush to 3 for a fixed cost share payment to offset their opportunity costs of participation sixty six percent of the 119 ranchers surveyed were willing to enroll ranch size income from livestock and deer hunting enterprises and perceptions about brush control costs were important explanatory variables in statistical analysis using probit and cragg models

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

the saving and investment nexus for china evidence from cointegration tests the saving and investment nexus as postulated by feldstein and horioka fh 1980 is revisited the saving investment correlation for china is estimated over the periods 1952 1998 and 1952 1994 the latter culminating in a period of fixed exchange rate regime amongst the key results it is found that saving and investment are correlated for china for both the period of the fixed exchange rate and the entire sample period with high saving investment correlation the results suggest that the chinese economy is in conformity with the fh hypothesis this is a valid outcome for in china capital mobility was fairly restricted over the 1952 1994 period as indicated by the relatively low foreign direct investment

the nexus between income inequality and co2 emissions in turkey abstract environmental degradation and income inequality are two of the most important international debates that await immediate resolution despite that their interaction in the environmental economics literature has been very little analysis the aim of this study is to examine the impact of income distribution on the co2 emissions in turkey during 1984 2014 an autoregressive distributed lag model ardl test is employed to determine possible long term and short term nexus among the series the ardl test results show that the series are cointegrated and that income inequality has a positive effect on co2 emissions we also find that the environmental kuznets curve ekc is valid in turkey the toda yamamoto causality test denotes that gini coefficient is the granger cause of co2 emission the results show that deterioration in income distribution will reduce environmental quality in turkey which validates that political economy approach is valid in turkey study results can be an important guide for policymakers reducing income inequality for a new strategy in the fight against environmental problems may lead to a win win situation for turkey and the international community
