growth and environmental quality testing the double convergence hypothesis abstract this paper discusses the double convergence hypothesis dch that the uncritical analysis of the so called environmental kuznets curve ekc implicitly implies according to the ekc empirical evidence would support the hypothesis that economic growth through a deterministic sequence of phases would produce cross country convergence in per capita output and as a by product convergence in the demand for environmental quality however factual analysis seems to reject the general hypothesis of convergence in per capita output limiting the validity of such an assessment to the case of homogeneous groups of countries this is why to test the dch the paper focuses on the original group of oecd countries for which the economic convergence turned out to be true this allows us to verify whether green and convergence follows as a consequence of economic convergence the paper also tests for a more equitable distribution of protection policies among countries unlike other studies which do not make the dch explicit and have focused on pollutant emissions this research explicitly tests for the double convergence using as a proxy for the demand for environmental quality the territory set aside for protected areas the results confirm that for the selected homogenous group of countries growth has accompanied the demand for environmental quality this happens both in terms of conditional and stochastic convergence

convergence in per capita carbon dioxide emissions among g7 countries a tar panel unit root approach the subject of this paper is the examination the convergence of per capita carbon dioxide emissions of the g7 countries during the 1960 2005 period in a nonlinear panel analysis framework in this approach first the linearity of the series was tested and when the linearity was rejected the threshold autoregressive tar panel unit root test which splits the data into two regimes was employed to examine the stationarity properties of the series because the null of linearity was rejected in the first step we tested the stationarity of the series using the tar panel unit root test in the tar panel unit root test we found that the united kingdom was the transition country whose per capita carbon dioxide co2 emissions determined the switch from one regime to the other the results showed that convergence existed in the first regime and divergence in the second when we tested whether absolute or conditional convergence existed we found that the per capita co2 emissions were conditionally converging in the first regime

stochastic divergence or convergence of per capita carbon dioxide emissions re examining the evidence this paper revisits the time series literature on the convergence of per capita carbon dioxide co2 emissions and examines the robustness of previous results using a sample of oecd countries for the period 1950 2002 we employ a battery of stationarity and unit root tests including those that allow for cross sectional dependencies within the panel we also correct for inaccuracies in previous studies that could result in a trend stationary series being labelled as converging even if it were actually diverging from the international average the body of evidence provided by our analysis suggests that per capita co2 emissions have not converged among oecd countries during the period under consideration this finding is of importance to both climate change policy makers and to those who construct climate change models

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

rural credit and agricultural supply in brazil the objective of this study is to determine the financing impact of total expenditure on the use of agriculture inputs fertilizers labor and pesticides and the output of cotton rice beans corn soybean and wheat in brazil we study the period 1976 2005 the analysis is based on duality applied to the production theory the output supplies and conditioned input demands are estimated from a translog multi output multi input restricted profit function where the total production credit is used as proxy of the total expenditure farmer expectations with respect to crop prices are incorporated to the estimation based on the quasi rational expectation model the output and input responses to the total expenditure are positive and statistically significant except for cotton wheat fertilizer and pesticides the short run output supply response to own prices is inelastic except for wheat which presents elastic response to its price acreage has a positive impact on the output supply and it is influenced by land productivity the main conclusion is that farmers face budget restrictions to purchase inputs and a government credit program might increase the agricultural supply

credit constraints credit unions and small scale producers in guatemala abstract efficient and equitable development outcomes may depend in part on whether formal financial institutions leave low wealth producers tightly constrained in their access to credit if so can cooperative institutions efficiently relax these constraints these issues are explored using survey data gathered from 950 small scale producer households in areas of guatemala with market oriented credit unions that mobilize savings and make unsubsidized loans nonprice rationing by banks is found to be common among lower wealth households while credit unions relax credit constraints for a significant portion of those rationed by banks but not the poorest of the study households

per capita carbon dioxide emissions convergence or divergence understanding and considering the distribution of per capita carbon dioxide co2 emissions is important in designing international climate change proposals and incentives for participation i evaluate historic international emissions distributions and forecast future distributions to assess whether per capita emissions have been converging or will converge i find evidence of convergence among 23 member countries of the organisation for economic co operation and development oecd whereas emissions appear to be diverging for an 88 country global sample over 1960 2000 forecasts based on a markov chain transition matrix provide little evidence of future emissions convergence and indicate that emissions may diverge in the near term i also review the shortcomings of environmental kuznets curve regressions and structural models in characterizing future emissions distributions

the impact of market friendly reforms on credit and land markets in honduras and nicaragua summary this article explores the impacts on credit access and agrarian structure of land market liberalization policies undertaken in honduras and nicaragua during the 1990s like liberalization efforts pursued in many latin american countries these market friendly reforms were designed to activate land transfers and enhance agricultural efficiency in large part by improving the access of the rural poor to both credit and land markets panel data sets gathered in honduras and nicaragua are used to compare title credit and land access patterns before and after the reforms descriptive nonparametric regression analyses show that despite major gains in titling across the land size spectrum and some increase in land market activity the other hoped for improvements in credit and land access did not occur and appear unlikely to occur without further policy attention to credit markets

convergence of per capita carbon dioxide emissions in the eu legend or reality abstract designing appropriate environmental and energy policies in order to meet the kyoto protocol s carbon dioxide co 2 reduction targets in the european union eu requires a detailed examination and thorough understanding of co 2 emission trends across the eu member states this paper investigates whether co 2 emissions have converged across 22 european countries over the 1971 to 2006 period the bayesian shrinkage estimation method is employed to do this work and the results reveal the following first the hypothesis of absolute convergence in per capita co 2 emissions is supported and a slight upward convergence is observed second the fact that countries differ considerably in both their speed of convergence and volatility in emissions makes it possible to identify different groups of countries third the results with respect to convergence do not vary much once the share of industry in gdp is accounted for in a conditional convergence analysis however a decreasing share of industry in gdp seems to contribute to a decline in per capita emissions these findings may carry important implications for both national and eu environmental policies

is there convergence in per capita renewable energy consumption across u s states evidence from lm and rals lm unit root tests with breaks abstract given the federal and state policy initiatives to curb fossil fuel consumption and expand the use of renewable energy sources in the u s this study investigates the convergence properties of per capita renewable energy consumption across u s states including the district of columbia in addition to cross sectional tests of and convergence our study employs lm and rals lm unit root tests with endogenously determined structural breaks to test for stochastic convergence traditional cross sectional tests indicate that both and convergence of per capita renewable energy consumption exists across u s states moreover our results also provides clear support for stochastic convergence of per capita renewable energy consumption for a majority of u s states including the district of columbia once allowance is made for structural breaks

have air pollutant emissions converged among u s regions evidence from unit root tests previous studies of income distribution have found evidence indicating that incomes across u s regions have converged supporting the prediction of the neoclassical growth model a potential shortcoming in these studies is that only one measure of well being is considered a measure of wealth linked to incomes or production this paper examines whether income convergence was accompanied by air pollutant emission convergence results from unit root tests provide some evidence that indicators of environmental quality have converged across u s regions during the 1929 1994 period

the relationship between credit and productivity in chinese agriculture a microeconomic model of disequilibrium credit is an important element in agricultural production systems it allows producers to satisfy the cash needs induced by the production cycle which characterizes agriculture preparation planting cultivation and harvesting of the crops are typically done over a period of several months in which very little cash revenue is earned while expenditures on materials purchased inputs and consumption must be made in cash cash income is received a short time after the harvest in the absence of credit markets farmers would have to maintain cash reserves so as to facilitate production and consumption in the next cycle the availability of credit allows both greater consumption and greater purchased input use and thus increases welfare of the farmers

internalizing co2 emissions via central banks financials evidence from the world researchers and policy makers have suggested tools to mitigate co2 emissions worldwide however there appears to be uncertainty in terms of policy effectiveness the objective of this paper is to develop an innovatively effective co2 internalizing mechanism worldwide which builds on currency in circulation as its core operational tool the study is based on a large sample of countries findings show that urbanization electric power consumption and trade positively impact on co2 emissions no evidence is found in favour of the environmental kuznets curve while the use of renewable energy reduces the level of co2 emissions the paper proposes a central bank carbon dioxide emissions internalizing fund which rests on quantitative and qualitative tools to ensure a truly effective mechanism in co2 emissions abatement quantitatively this implies the use of a direct tax on currency in circulation and a conversion penalty in the fund qualitatively there is the need to establish a global institution which would ensure that funds flow to the most polluting sectors in each country in view of unleashing the strongest decline in co2 emissions

are co2 emission levels converging among industrial countries time paths of carbon dioxide emissions intwenty one industrial countries are examinedfrom 1960 1997 to test for stochastic andconditional convergence both panel unit roottests and cross section regressions areperformed overall we find significantevidence that co2 emissions haveconverged

who benefits from partial tax coordination in this paper we investigate whether partial tax coordination is beneficial to countries within and outside a tax union in which countries are supposed to compete in taxes and infrastructure our results demonstrate that a subgroup of countries agreeing on a common tax rate can harm both member and nonmember states this is in contrast to the classical findings that partial tax harmonisation is pareto improving when a minimum tax rate is imposed within a tax union we demonstrate that it does not necessarily improve the welfare of the member countries moreover both the high tax and low tax countries can be worse off this conclusion is at odds with the classical result that a high tax country benefits from the imposition of a lower tax bound

the causal factors of international inequality in hbox co _ 2 emissions per capita a regression based inequality decomposition analysis this paper uses the possibilities provided by the regression based inequality decomposition fields in res labor econ 22 1 38 2003 to explore the contribution of different explanatory factors to international inequality in hbox co 2 emissions per capita in contrast to previous emissions inequality decompositions which were based on identity relationships this methodology does not impose any a priori specific relationship thus it allows an assessment of the contribution to inequality of different relevant variables in short the paper appraises the relative contributions of affluence sectoral composition demographic factors and climate the analysis is applied to selected years of the period 1993 2007 the results show the important though decreasing share of the contribution of demographic factors as well as a significant contribution of affluence and sectoral composition

dynamics and drivers of per capita co2 emissions in asia abstract the aim of this paper is to document recent trends in asia s co2 emissions and explore the mechanisms that drive those emissions for fourteen countries over the period 1971 to 2017 we apply a sequential method which has a strong relationship to policy indicators first an analysis of the dynamics is undertaken to identify if convergence is occurring followed by a study of the determinants of those dynamics this approach overcomes some of the limitations of previous work analyzing emission convergence by focusing on country specific characteristics such as energy mix and energy efficiency the analysis reveals per capita co2 emissions energy intensity carbonization and per capita incomes are slowly converging over the full sample yet this behavior is not uniform there were differences in transition paths prior to and after the asian financial crisis the per capita income driver was the most important driver in explaining the dynamics and variation of emissions while carbonization and energy intensity drivers were less pronounced the analysis reveals that the energy needs of the region s extraordinary economic growth favored fossil fuels and a surprising revelation is that despite having different per capita income levels china korea and vietnam all share a common convergence path this paper provides further evidence against using carbon intensity solely as a target for climate policy

drivers of industrial and non industrial greenhouse gas emissions abstract though there has been extensive analysis of the drivers of aggregate carbon dioxide emissions from fossil fuel combustion and cement production there has been much less analysis of the drivers of greenhouse gases in general and especially of aggregate emissions of greenhouse gases from agriculture forestry and other land uses which we call non industrial emissions in this paper we statistically analyze the relationship between both industrial and non industrial greenhouse gas emissions and economic growth and other potential drivers for 129 countries over the period from 1971 to 2010 our analysis combines the three main approaches in the literature into a single framework for investigating the evolution of emissions and income we find that economic growth is a driver of both industrial and non industrial emissions though economic growth has twice the effect on industrial emissions the time effect is negative for both sources of emissions though this effect is larger for non industrial emissions there is also convergence in emissions intensity for both types of emissions but given these other effects there is no evidence for an environmental kuznets curve

distribution dynamics of co2 emissions this paper uses nonparametric methods to examine the convergence in co2 emissions per capita on a sample of 100 countries for the period 1966 1996 industrial countries show a convergence pattern however there is little evidence of convergence for the whole sample

are shocks to ecological balance permanent or temporary evidence from lm unit root tests abstract ecological balance can be described as the difference between ecological footprint and biocapacity it is an important indicator of sustainable and environmental development in this regard the current study aims to determine whether policies on ecological balance are effective in g7 and e7 countries covering the period of 1961 2016 to this end we use the lagrange multiplier lm unit root test lm unit root test with structural breaks and fourier lm unit root test as well as more powerful versions of these tests to investigate the stationarity of the ecological balance we also examine the effectiveness of policies regarding ecological footprint and biocapacity the empirical results obtained from both linear and non linear unit root tests show that ecological balance is stationary in germany italy japan the us china india indonesia mexico and turkey while it is non stationary in the remaining five countries however the findings based on the structural break unit root tests suggest that ecological balance is stationary in more countries finally the overall results indicate that shocks to the ecological balance in g7 countries have a more permanent effect than in e7 countries therefore g7 countries can better apply environmental protection policies than e7 countries can in the long term in brazil canada france russia and the uk environmental policies can be effectively implemented to regulate ecological balance

expenditure constraints and profit maximization in u s agriculture the u s agricultural sector is undergoing some of its most severe financial problems since the great depression numerous reports have emerged of large numbers of farmers being unable to obtain short term oper

equilibrium credit rationing of small farm agriculture it is often argued that externally imposed contractual restrictions lead to inequitable credit rationing this paper argues that unrestricted laissez faire markets may also inequitably ration credit a formal model which grants borrowers autonomy in credit application and use demonstrates that adverse incentive and selection effects may cause banks to endogenously impose interest rate restrictions and ration small farms out of the credit market consequently liberalization of financial markets may be insufficient to guarantee small farms access to credit
