improvement of technical efficiency of firm groups abstract cooperation between firms can never improve the technical efficiency of any firm coalition the directional distance function by virtue of its additive nature is a useful tool that outlines this impossibility in this paper the additive aggregation scheme of input output vectors is generalized according to an aggregator accordingly cooperation between firms may increase the technical efficiency of the firm group this improvement is shown to be compatible with nonjoint semilattice technologies that bring out either output or input weak complementarity firm games are investigated to show that firms may merge on the basis of their inputs due to constraints imposed on outputs conversely they may merge with respect to the outputs they can produce because of limitations imposed on inputs

is economic growth good for the poor tracking low incomes using general means in this paper we propose the use of an alternative methodology to track low incomes based on atkinson s 1970 family of equally distributed equivalent income functions which are called general means here we provide a new characterization of general means that justifies their use in this context our method of evaluating the effects of growth on poor incomes is based on a comparison of growth rates for two standards of living the ordinary mean and a bottom sensitive general mean the motivating question is to what extent is growth in the ordinary mean accompanied by growth in the general mean a key indicator in this approach is the growth elasticity of the general mean or the percentage change in the general mean over the percentage change in the usual mean our empirical analysis estimates this growth elasticity for a data set containing 144 household surveys from 20 countries over the last quarter century among other results we find that the growth elasticity of bottom sensitive general means is positive but significantly smaller than one this suggests that the incomes of the poor do not grow one for one with increases in average income

democracy comes to europe franchise extension and fiscal outcomes 1830 1938 abstract this paper examines the relation between public spending and the spread of democracy in western europe during the period 1830 1938 our data set includes measures of the size of the electorate the election rule and electoral participation as well as measures of the size and composition of central government expenditures for 12 countries we estimate panel regressions and find that 1 the gradual lifting of socio economic restrictions on the voting franchise contributed to growth in government spending mainly by increasing spending on infrastructure and internal security 2 the female suffrage had a weak positive effect through spending on health education and welfare 3 the change from majority to proportional rule which took place in 10 of the countries did not contribute to growth in government spending and held back spending on health education and welfare 4 there exists weak complementarity between economic development and the spread of democracy

are macroeconomic policies better in curbing air pollution than environmental policies a dsge approach with carbon dependent fiscal and monetary policies abstract the environmental impacts of macroeconomic policies and their interaction with climate policies are under researched in the existing literature this paper compares the effectiveness of standard macroeconomic tools fiscal and monetary policies with carbon taxation in curbing air pollution by using an environmental dynamic stochastic general equilibrium e dsge model we show how government expenditure interest rate and carbon tax rate should vary over time in order to stabilize carbon emission levels we find that i while all the aforementioned policies could stabilize carbon emissions their underlying mechanisms are different fiscal monetary and carbon tax policies uniquely and respectively lead to a reduction in abatement effort income tax revenue and general price level ii with economic expansions driven by total factor productivity tfp shocks fiscal policy is the only policy that could maintain the emission levels and simultaneously improve household welfare in term of consumption and labor iii regarding the interaction between carbon and macroeconomic policies carbon taxation should complement monetary policy while it should not respond to fiscal policy

ethical social index numbers and the measure ment of effective tax benefit progressivity in this paper we propose a general method for constructing measures both relative and absolute of effective tax benefit progressivity from social welfare functions relative measures compare the after tax or benefit distribution of income with the distribution that would result if the burden were imposed proportionally absolute measures use the equal taxation of individuals as a benchmark these indices are related to relative and absolute indices of inequality our relative indices are generalizations of the gini index based musgrave thin measure of effective progressivity we compare our general indices to the proposals of kakwani khetan and poddar and suits

energy consumption and the influencing factors in china a nonlinear perspective abstract different from many studies on energy kuznets curve this paper does not directly consider income factor but conducts a nonlinear study on per capita primary energy consumption and electricity consumption in china whose economic development is considered investment driven in which government macroeconomic policies especially government expenditure plays a very important role in particular this paper attempts to compare the different impacts of government expenditures and the other influencing factors on energy consumption based on the results of the threshold regression in the future with the further development of the economy the driving force of labor population growth will slow down comparing with primary energy the relationship between electricity consumption and its influencing factors will change later and the difference in the effects of the influencing factors is mainly reflected in the formation of capital stock investment and the development of urbanization government expenditure on private goods may not be always as inefficient in energy consumption and cleaner production as previously thought in the literature meanwhile the growth of government expenditure on public goods will become a powerful driving factor which indicates that the government needs to assess its overall impact on energy consumption and energy efficiency when participating in the provision of public goods the paper also found that when studying the issue of energy consumption and regional differences in china the geographic classification of eastern central and western regions may not be appropriate grouping according to energy consumption levels may be one of the better options and the distribution of energy consumption levels in china s provinces is consistent with the distribution of government expenditure levels the estimation results also provide us with important policy implications the government expenditure in education is of great importance and it can produce a strong energy saving effect through technological progress

exploring the determinants of emerging bioenergy market participation abstract individual biomass producers will play a strong role in the emergence of robust and sustainable bioenergy markets research on what drives their participation however is substantial but fragmented despite a recognition of producer heterogeneity there have also been few comparative analyses of drivers of bioenergy market participation across feedstock types producer groups and geographic regions through narrative review and network analysis the following review of the bioenergy market participation literature generates both an increased appreciation of how bioenergy market participation is assessed in existing research and how social network analysis may be further employed as a tool for literature review across 41 studies selected for qualitative review and a subset of 22 selected for quantitative review the analysis reaches two central conclusions the first pertains to the findings of the literature itself suggesting that a variety of non production objectives structural and social constraints and market related attributes influence bioenergy market participation decisions a second conclusion is that the assessment of these factors varies significantly across the literature for both user group and feedstock type further examination of the individual variables within these segments of the literature as well as of authorship patterns across them suggests that this variation may rise from differences in the subject matter itself and not from differing perspectives of the researchers undertaking the work should disparities in the literature be reflective of actual socio economic differences in their respective markets policies or programs targeted to individual feedstock types or user groups may be more effective in encouraging participation than uniform national policy initiatives

inequality in male and female earnings the role of hours and wages the authors decompose annual earnings into hours of work and hourly earnings and analyze male female differences in earnings inequality using canadian data their results indicate that the larger female inequality in earnings is due to a greater inequality in the distribution of hours of work the distributions of wages for men and women are either statistically indistinguishable or more equal for women the authors compare two data points 1988 and 1981 and find the same structure in the gender comparisons also changes between 1988 and 1981 in earnings inequality are generated from movements in the hours distributions copyright 1996 by mit press

relationship between forest resources and economic growth empirical evidence from china abstract natural resources especially forests are critical to china s sustainable development in recent years effective utilization of forest resources has become a significant concern in china in this study on the basis of the environmental kuznets curve ekc hypothesis the relationship between forest resources and economic growth is examined using panel data from 30 provinces in china for the period 2002 2015 and the generalized method of moments gmm approach to control for potential endogeneity the empirical results indicate that with continuous economic growth the timber output and area of afforestation would at first increase and then decrease after reaching the corresponding turning points given the considerable regional gap in economic and social development three regions of china were investigated to perform a more in depth analysis evidence observed for the country and the three regions suggests an ekc for forest resources these findings indicate positive effects of china s pursuit of a more balanced growth path where forest resources would be less consumed and more actively protected

the effects of fiscal policy on co2 emissions evidence from the u s a abstract this paper examines the effects of fiscal policy on co2 emissions using vector autoregressions on u s quarterly data from 1973 to 2013 in particular we analyze the short and mid term interactions between fiscal policy and emissions by using sign restrictions to identify the policy shocks we construct the impulse responses to linear combinations of fiscal shocks corresponding to the scenarios of deficit financed spending and deficit financed tax cuts to consider possible variations of the effect of fiscal policy according to the sources of pollution we distinguish between production and consumption generated co2 emissions the results point out that the implementation of expansionary fiscal spending provides an alleviating effect on emissions from both sources of the pollutant whereas deficit financed tax cuts are associated with an increase on consumption generated co2 emissions the exact pattern of the effects depends on the source of emissions the scenario of fiscal policy that is implemented and the functional class of government expenditure being increased

a consistent multidimensional pigou dalton transfer principle abstract the unidimensional pigou dalton transfer principle demands that a regressive transfer in income a transfer from worse off poor to better off rich decreases social welfare in a multidimensional setting the direct link between income or any other attribute and individual well being is absent we interpret the social welfare level of a distribution in which each individual has the same bundle as the individual well being level we define regressivity on the basis of this individual well being ranking in a setting with both transferable and non transferable attributes the imposition of the ensuing consistent pigou dalton principle forces individual well being to have a quasi linear structure in the transferable attributes since we allow for transferable and non transferable attributes our result provides a normative underpinning for criteria in the distinct literatures of multidimensional inequality measurement only transferable attributes and of needs one transferable and one non transferable attribute

relative price changes and inequality in the size distribution of various components of income this article uses a comprehensive model of economic inequality to examine the impact of relative price changes on inequality in the marginal distributions of various income components in which the marginal distributions are derived from a multidimensional joint distribution the multidimensional joint distribution function is assumed to be a member of the pearson type vi family that is it is assumed to be a beta distribution of the second kind the multidimensional joint distribution is so called because it is a joint distribution of components of income and expenditures on various commodity groups gini measures of inequality are devised from the marginal distributions of the various income components the inequality measures are shown to depend on the parameters of the multidimensional joint distribution it is then shown that the parameters of the multidimensional joint distribution depend on the relative prices of various commodity groups and several other specified exogenous variables thus knowle

consumption needs and inequality most empirical studies demonstrating a u turn in inequality in the united states are based on the distribution of income however utility is derived from the consumption of goods and services and there are many reasons to expect the distribution of expenditure to be different from the distribution of income the author demonstrates that consumption based inequality indexes actually decrease over the postwar era this conclusion differs from the stylized facts because of differences in the income and expenditure distributions differences also arise from the inclusion of equivalence scales to account for the different needs of heterogeneous households copyright 1994 by economics department of the university of pennsylvania and the osaka university institute of social and economic research association

social criteria for evaluating population change abstract many applications of economic analysis require social evaluations of alternatives involving different numbers of people in this paper we use the tools of social choice theory to provide an axiomatic formulation of this problem it yields a class of social criteria called critical level generalized utilitarianism this class and its implications are compared with other criteria and are found to yield intuitively appealing results

income volatility of energy crops the case of rapeseed abstract the adoption of energy crops may generate significant benefits from reduced foreign energy dependence improved rural economies and achieved environmental goals nevertheless important issues arise as these crops are strongly competed by other presumably more standard uses of farmland and their choice will be restrictive unless profit becomes a powerful motive for farmers the abolishment of specific policies supporting first generation biofuels gives rise to the question whether the tactic of bioenergy land use change is just to be abandoned by european farmers the present paper endeavours to evaluate the reduction in income volatility in the case of the rapeseed energy crop a cultivation extensively used in biofuels in the european union employing the concept of entropy the results provide a vague picture regarding the limitations in rapeseed income volatility among the european member states consequently the issue of income uncertainties as a determinant of bioenergy cropland demand has been left pending the innovation of the study lies in the use of entropy concept and the kapetanios and shin unit root test in the case of income volatility for energy crops in the european context the estimation of the random components with the assistance of auto regressive integrated mean average models may provide a tool for confining income uncertainties with the assistance of other policy schemes including insurances within the common agricultural policy

the environmental kuznets curve for pm2 5 pollution in beijing tianjin hebei region of china a spatial panel data approach abstract the purpose of this study is to exam the existence of environmental kuznets curve ekc of pm2 5 pollution in the beijing tianjin hebei bth region of china as one of the most important economic growth poles in china bth region has long been suffering from air pollution especially pm2 5 pollution thus in this study we utilized satellite observations of pm2 5 pollution and panel data of 13 cities in bth region from 1998 to 2016 to investigate the relationship between economic growth and pm2 5 pollution after verifying the spatial effect of pm2 5 pollution by spatial statistical analysis the spatial econometric model spatial durbin model sdm was chosen over the non spatial model in the examination of ekc the results showed that 1 the relationship between economic growth and pm2 5 pollution presented a significant inverted u shaped pattern though bth region is still in the upward section there is a hope that it will cross the point and enter the downward section in the future 2 the turning points of ekc would happen later with spatial effect considered compared to the result of non spatial model 3 the turning point of ekc would not happen until the region enter the post industrial economy stage moreover though some of the cities in bth region have entered post industrial stage none of them has cross the turning point of ekc results of this study indicate a promising future in the control of pm2 5 pollution as well as provide suggestions to put more emphasis on regional cooperative governance in air pollution control for the policy makers

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

the effects of government spending on deforestation due to agricultural land expansion and co2 related emissions this paper examines the effect of changes in government spending level and composition on deforestation due to agricultural land expansion and related carbon dioxide emissions our theoretical model shows an unintended consequence from increased government spending and widening social safety nets in developing countries where agricultural land expansion significantly affects forest cover there is an increase in deforestation and carbon dioxide emissions from land use change our empirical tests show that an increase in total government spending significantly increases forest land clearing for agricultural production in the short run leading to more carbon dioxide emissions however there is no long run statistically significant effect on the steady state forest cover and carbon dioxide emissions

should governments stop subsidies to private goods evidence from rural latin america abstract this paper empirically documents the effects of subsidizing private goods to the detriment of the government s supply of public goods we use a new data set from the rural sector in fifteen latin american countries over the period 1985 2001 collected using a methodology that allows us to separate government subsidies to private goods from expenditures in the provision of public goods the econometric evidence shows that the government s decision to subsidize either private or public goods has dramatic consequences for economic development reducing the share of subsidies to private goods or equivalently increasing the share of public goods in the government s budget has ceteris paribus a large and significant positive impact on rural per capita income reduces certain undesirable environmental effects associated with output expansion and contributes to poverty reduction

how much inequality can we explain a methodology and an application to the united states we develop two simple measures of how much inequality is explained by individual population characteristics or groups of characteristics analogous to r2 in regression analysis we investigate the measures empirical implementation using several alternative theoretically consistent approaches to inequality decomposition results are illustrated using us psid income data explaining the level of and trends in inequality is an intriguing topic but one that is often dependent on a researcher s particular approach to inequality measurement sometimes the approach is simply one that accords with intuition sometimes principles of applied welfare economics or statistical analysis are invoked the particular approach adopted is important the issue of the explanation of inequality is not just a matter of computational procedure but can significantly affect our understanding of economic inequality and can potentially guide the design of economic policy in this paper we develop new summary measures of explanation the income inequality literature s analogue of the r2 statistic used in regression analysis using an approach which pays particular attention to theoretically consistent methods for inequality decomposition and illustrate them using a specially cleaned set of us psid data an important example of the explanation issue that is relevant to current policy debate is the suggestion that personal attributes and labour market status are major determinants of interpersonal income differences formal economic models stress the role of labour market opportunities in the structure of the income distribution other types of analysis emphasise the importance of characteristics such as ethnicity age and gender it is commonly supposed that these factors explain a major part of observed income inequality and of changes in inequality in the case of the united states we show that this conjecture is empirically unfounded the supposed determinants of inequality in fact account for only a very small part of the actual inequality of broadly defined personal income

the effect of government expenditure on the environment an empirical investigation abstract this paper examines the impact of government spending on the environment using a panel of 77 countries for the time period 1980 2000 we estimate both the direct and indirect effects of government spending on pollution the indirect effect in particular operates through the impact of government spending on income and the subsequent effect of the income level on pollution to take into account the dynamic nature and the potential endogeneity in the relationships examined appropriate econometric methods are used for so2 government spending is estimated to have a negative direct impact on per capita emissions while the direct effect is insignificant on co2 pollution the indirect effect on so2 is negative for low income levels and becomes positive as income increases while it remains negative for co2 for the most part of the sample range the resultant total effects follow the patterns of the indirect effects which dominate their respective direct ones for each pollutant policy implications from the results vary depending on the income level of the considered countries

corruption and the environmental kuznets curve empirical evidence for sulfur abstract we investigate how corruption influences the income level at the turning point of the relationship between sulfur emissions and income using a wide cross national panel of countries at different levels of development and with different degrees of corruption our results support the environmental kuznets curve hypothesis for sulfur we find evidence that the higher the country s degree of corruption the higher the per capita income at the turning point suggesting different income pollution paths across countries due to corruption we build upon a new specification for the ekc developed by bradford et al 2005 that avoids using nonlinear transformations of potentially nonstationary regressors in panel estimation also we account for the indirect impact of corruption on emissions through its impact on per capita income our main findings remain unchanged when we investigate additional heterogeneity allowing for different income slopes across richer and poorer countries

the cyclical behaviour of fiscal policy evidence from the oecd this paper addresses the topic of cyclicality in scal policy in particular we show that the level of cyclicality varies across spending categories and across oecd countries in line with leading theories of scal cyclicality we show that countries with volatile output and dispersed political power are the most likely to run procyclical scal policies wage government consumption is highlighted as the most important channel by which these variables affect scal cyclicality

modelling farmer uptake of perennial energy crops in the uk abstract the uk biomass strategy suggests that to reach the technical potential of perennial energy crops such as short rotation coppice src willow and miscanthus by 2020 requires 350 000 hectares of land this represents a more than 20 fold increase on the current 15 546 hectares previous research has identified several barriers to adoption including concerns over security of income from contracts in addition farmers perceive returns from these crops to be lower than for conventional crops this paper uses a farm level linear programming model to investigate theoretical uptake of energy crops at different gross margins under the assumption of a profit maximising decision maker and in the absence of known barriers to adoption the findings suggest that while src willow at current prices remains less competitive returns to miscanthus should have encouraged adoption on a wider scale than at present this highlights the importance of the barriers to adoption recently announced contracts for miscanthus appear to offer a significant premium to farmers in order to encourage them to grow the crops this raises the question of whether a more cost effective approach would be for government to provide guarantees addressing farmers concerns including security of income from the contracts such an approach should encourage adoption at lower gross margins

efficient firm groups allocative efficiency in cooperative games abstract the concept of efficiency in groups postulates that a coalition of firms has to record a smaller distance toward the aggregate technology frontier compared with the sum of individual distances efficiency analysis either allocative or technical is defined with respect to cooperative firm game in order to provide operational distance functions the so called pseudo distance functions these pseudo distances belong to the core interior of the allocative firm game in other terms any given firm coalition may always improve its allocative efficiency we prove that such a result is impossible for technical efficiency i e the technical efficiency cannot increase for all possible coalitions

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

unit consistent decomposable inequality measures this paper introduces a new axiom the unit consistency axiom into inequality measurement this new axiom requires the ordinal inequality rankings rather than the cardinal indices to be unaffected when incomes are expressed in different units i argue that unit consistency is an indispensable axiom for the measurement of income inequality when unit consistency is combined with decomposability i show that the unit consistent decomposable class of inequality measures is a two parameter extension of the one parameter generalized entropy class the extended class accommodates a variety of value judgments and includes different types of inequality measures

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

the willingness of farmers to engage with bioenergy and woody biomass production a regional case study from cumbria abstract in this paper we explore the willingness of cumbrian farmers to switch land use from food production to biomass production in a landscape where food production is both heavily subsidised and the area is a centre for tourism this is against a policy background of a switch of subsidies from food production to environmental benefits increased concerns about emissions from farming and an increased demand for renewable energy we identified an awareness of new markets for renewable energy alongside increasing volatility of other crops against a background of increasing demand for food from this our conclusions are that the main short term opportunities for increasing biomass production in this region are through intensifying management of existing woodlands in the medium term as the financial case for biomass crops becomes more certain we can envisage a tipping point which would favour a switch from marginal agricultural land to biomass

is there an environmental kuznets curve for sulfur abstract most existing estimates of the environmental kuznets curve ekc for sulfur which use samples of mainly high income countries indicate a maximum emissions turning point at middle to lower high income levels of gdp per capita we use a larger and more globally representative sample than previous sulfur ekc studies we find that sulfur emissions per capita are a monotonic function of income per capita when we use a global sample and an inverted u shape function of income when we use a sample of high income countries a model estimated in first differences results in a monotonic ekc when estimated with both high income and global samples reductions in emissions are time related rather than income related

income and democracy existing studies establish a strong cross country correlation between income and democracy but do not control for factors that simultaneously affect both variables we show that controlling for such factors by including country fixed effects removes the statistical association between income per capita and vari ous measures of democracy we present instrumental variables estimates that also show no causal effect of income on democracy the cross country corre lation between income and democracy reflects a positive correlation between changes in income and democracy over the past 500 years this pattern is con sistent with the idea that societies embarked on divergent political economic development paths at certain critical junctures jel d7 e 1
