the private wage sector in cote d ivoire homogeneity or heterogeneity one dominant feature of economic development is change in the structure of the economy some sectors expand while others shrink in response to changes in output markets considerable adjustments must take place in factor markets as well development will therefore proceed more speedily when barriers in the factor markets are minimal whether or not barriers in the labor market exist macroeconomic discussions of labor markets usually assume uninhibited flows between sectors 13 similarly a large literature on earnings of wage workers has treated the wage sector as a homogeneous part of the labor market yet if the wage sector is heterogeneous model estimates have no empirical meaning and policy recommendations have no foundation

the public private wage differential in a poor urban economy the occupational structure of wages is generally more compressed in high than in low income countries the role of non market forces in determining the structure of wages is of interest for reasons of allocative efficiency as well as for distributional concerns this paper considers how wage differentials may be generated between the public and private sectors of a developing economy data from a 1971 household survey of the tanzanian urban wage labor force are used to determine the pattern of wage differences across employer groups after standardizing by worker characteristics public sector employees are found to have earned a substantial wage premium over workers employed in the private sector the non market character of these differentials is examined in light of a number of hypotheses on public sector wage determination

income distribution and environmental quality in china a spatial econometric perspective abstract paying heed to a surge of concern about the serious and continuous environmental degradation that is currently being witnessed in china in this paper we investigate whether income distribution contributes to environmental deterioration environmental degradation can be linked not only to income growth we argue but also to increases in income inequality the study calculated the gini coefficient of 31 province using a data set of 403 city level data in mainland china and estimated the linkage between income distribution and environmental deterioration utilizing balanced data for 31 chinese provinces during the period 1996 2015 first the degree of environmental pollution was calculated by constructing a comprehensive index system which was formulated using the entropy method based on six environmental indicators then a spatial panel regression model was also employed in order to estimate whether income inequality is likely to be a relevant factor in environmental deterioration in china the estimation results showed that using the index and spatial analysis techniques significant spatial positive agglomeration were found existing between chinese provinces in terms of their levels of environmental degradation the influencing factors estimation results substantiated the existence of an invert u shaped relation lending support to the environmental kuznets curve theory more importantly the study found that income inequality played a significant role in preventing environmental degradation suggesting that an appropriate level of income inequality over a delimited period is beneficial to improving environmental quality it should however also be emphasized that optimizing the country s income distribution is remains an important long term task for the chinese government other factors were found to exert different types and magnitudes of impacts on environmental pollution results showed that many factors for instance energy intensity the share of secondary industry population density and foreign direct investment contribute to environmental deterioration conversely our findings also indicate that rising urbanization levels can have a positive effect on environmental quality in addition no clear evidence was found to suggest that local government expenditure is related to environmental degradation

capacity choice and water management in hydroelectricity systems this paper proposes a simple two period model that captures the seasonal pattern of water inflows and electricity demand observed in many countries where hydropower is a major source of electricity supply the model characterizes the effects of different inflows pattern on the optimal water management capacity and the associated electricity production and price the first best capacity is a non monotonic function of water inflows which provides a rationale for the observed differences in reservoirs sizes across hydropower systems around the world the monopoly solution is qualitatively similar to the first best outcome and the privatization of hydroelectric power generation systems does not always imply a social welfare loss

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

income inequality and co2 emissions in the g7 1870 2014 evidence from non parametric modelling abstract we examine whether income inequality effected carbon emissions in what are now the world s wealthiest countries over the period 1870 2014 employing a non parametric panel estimation method with cross sectional and time varying coefficients we find that the relationship between income inequality and co2 emissions is highly non linear in terms of signs and significance the nonparametric coefficient function for income inequality is found to vary over the period 1870 2014 income inequality exhibits a significant positive effect from 1870 to 1880 and a significant negative impact from 1950 to 2000 on co2 emissions we also find that for extended periods between 1881 and 1949 and between 2000 and 2014 there is no significant relationship between the two variables

sector choice multiple job holding and wage differentials evidence from poland this article uses data from poland to investigate the role played by wage differentials between the public and private sectors in influencing sector choice and the decision to moonlight standardising for worker characteristics and allowing for sector selection effects we find i a substantial private sector wage premium ii wage differentials are a significant determinant of sector choice and iii the desire to moonlight is particularly strong among those who face the greatest wage gap that is university educated employees

liberalizing the energy markets of western europe a computable equilibrium model approach using a computable equilibrium model the short run effects of a radical liberalization of the west european natural gas and electricity markets are examined in each model country oil gas coal and electricity are produced traded and consumed there are world markets for oil and coal and well integrated competitive markets for gas and electricity in western europe gas and electricity are transported and traded across markets under the assumption of ideal third party access regimes for transportation and limited capacities in the transportation networks it is found that relative to the data year 1996 radical liberalization reduces the average end user price of natural gas by around 20 and the average end user price of electricity by around 50 the supply of electricity increases by around 20 mainly due to increased coal power production after such liberalization coal power emerges with the largest market share of electricity production in western europe

design and implementation of carbon cap and dividend policies an important concept in discussions of carbon management policies is cap and dividend where some fraction of the revenues of an auction on emission allowances is returned to citizens on an equal per capita basis this policy tool has some important features it emphasizes the fact that the atmosphere is a common property resource and it is a highly transparent measure that can be effectively used to protect the income of low income individuals in this paper we examine this policy in the california context and focus on the costs and impacts of a cap and dividend scheme when applied to carbon emissions associated with electricity natural gas and transportation services we find that cap and dividend can effectively be used to address the economic impacts of carbon management policies making them progressive for the lowest income members of society we find that the majority of households receive positive net benefits from the policy even with the government retaining half of the auction revenue if auction revenues are instead dedicated only to low income households the majority of low income households can be fully compensated even with the state government retaining upwards of 90 of auction revenues for other purposes

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

social cost benefit analysis of electricity interconnector investment a critical appraisal abstract this paper examines the economic analysis social cost benefit analysis underlying two decisions to build an interconnector norned and the east west interconnector in europe the main conclusion is that current interconnector and transmission investment decisions in europe are unlikely to maximize social welfare the arguments are as follows i it is unclear how much demand for transmission capacity and interconnectors actually exists and thus the benefits of investment are unclear ii both analyses underlying the investments studied are incorrect to the point where in one case even the sign may be wrong iii the main criticism concerns the fact that they do not take the resulting changes in generator investment plans into account and ignore the potential benefits of increased competition iv several smaller issues can be improved such as the discount rate used v decisions at the european level are taken very differently and approval may depend on which authority grants approval vi interconnector decisions receive the most attention although most money goes to transmission investments two research recommendations for future improvements are formulated

job queues and the union status of workers this paper develops a model of the determination of the union status of workers that allows for the possibility of queuing for union jobs the empirical results derived using a sample from the university of michigan panel study of income dynamics are supportive of the queuing hypothesis the no queue model can be rejected using a likelihood ratio test this suggests that a simple probit or logit model for union status is misspecified because it is not based on any consistent behavioral theory an important implication of the model is that because most new entrants to the labor market prefer union jobs but cannot get them and because accrual of nonunion seniority makes workers progressively less likely to desire union jobs the union status of workers is largely determined by their success in being selected from the queue early in their working life

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

does income inequality facilitate carbon emission reduction in the us abstrct considering the short and long term impacts of income inequality on carbon emissions as well as the heterogeneity of the emission distribution this paper employs panel ardl and quantile regression models to analyze the effect of income inequality on carbon emissions across us states the findings suggest that higher income inequality increases us carbon emissions in the short term whereas it promotes carbon reduction in the long term furthermore we find that the absolute values for the coefficients on income inequality in the states from the 70th to the 90th quantiles are larger than those from the 10th to the 40th quantiles this indicates that income inequality reduces more carbon emissions in states with higher per capita carbon emissions the results provide important insights for policy makers to improve the quality of economic development and address climate change

decentralizing hydro power production we analyse the production of electricity from n power stations in a dynamic model each power station s production of electricity is constrained by the quantity of water available to it supply constraint as well as limitations on reservoir capacity storage constraint we show that hydro power production can lead to two sources of welfare loss suboptimal management of water resources and the exercise of market power a monopolist minimizes the first source of inefficiency whereas decentralized production in a competitive environment minimizes the second the decision to introduce competition in hydropower production must account for these two opposite effects jel classification l11 q48 decentralisation de la production d hydroelectricite nous analysons la production d hydroelectricite par n centrales dans un modele dynamique la production de chaque centrale est contrainte par la quantite d eau disponible contrainte d approvisionnement et la capacite du reservoir contrainte de stockage nous demontrons que la production hydroelectrique peut donner lieu a deux types d inefficacite la gestion sous optimale des ressources hydrauliques et l exercice de pouvoir de marche l entreprise monopolistique minimise la premiere inefficacite alors que la production decentralisee dans un marche concurrentiel minimise la deuxieme la decision d introduire la concurrence dans la production d hydroelectricite doit tenir compte de ces deux effets opposes

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

the supply of off farm labor a random coefficients approach a joint model of off farm labor decisions for farm operator and spouse is presented attention is given to operator and spouse participation decisions as well as associated problems of multiple sample selectivity biases two stage fixed and random coefficient methods corrected for possible selectivity biases are used to estimate supply function parameters results indicate that supply function parameters are random variation in important supply parameters is investigated results also illustrate the importance of spouse decisions on off farm labor supply function structure

power distribution the environment and public health a state level analysis abstract this paper examines relationships among power distribution the environment and public health by means of a cross sectional analysis of the 50 us states a measure of inter state variations in power distribution is derived from data on voter participation tax fairness medicaid access and educational attainment we develop and estimate a recursive model linking the distribution of power to environmental policy environmental stress and public health the results support the hypothesis that greater power inequality leads to weaker environmental policies which in turn lead to greater environmental degradation and to adverse public health outcomes

trade and price variation in an integrated european power market this paper examines the potential gains in terms of increased social surplus from integrating the power markets in europe and assesses the scope for free seasonal and diurnal trade in a setting of third party access tpa we construct an equilibrium model at the level of the wholesale markets taking account of the existing power generating infrastructure of varying flexibility as well as the existing transmission network interconnecting the countries involved the model indicates an overall gain from integrating the power markets electricity prices are substantially reduced for all regions involved thus implying a significant redistribution of income from producers to consumers trade flourishes with regions establishing themselves as either pure exporters pure importers or as intermediaries acting as transit countries

the demand for labor market structure an economic approach this paper formulates and estimates a model for the determination of employer and union demand for multiemployer vs single employer bargaining units utility maximizing risk averse firms and unions are both assumed to weigh the impact of each type of bargaining unit on the expected level and variability of profits and wages respectively the model is tested on a 1975 sample of 3 486 individual collective bargaining agreements because either party can generally leave a multiemployer unit without the other party s consent a partially observed bivariate probit model is used to estimate demand for structure it is found that the forgone profits due to a multiemployer unit relative to a single firm unit lower firm demands for this type of unit while forgone wages in a multiemployer unit relative to a single firm unit lower union demand for this type of unit

earnings determination and labour markets gran santiago chile 1978 abstract the purpose of this study is twofold first to ascertain whether or not there are statistical differences in the structure of earnings functions among workers in various sectors of economic activity second to provide a test of the human capital approach in the explanation of earning differentials among wage earners using individual characteristics of full time wage earners in santiago the results show that the structures of earnings functions are not statistically different across sectors of economic activity also the application of a human capital model shows that about 50 percent of the relative dispersion of earnings may be attributed to differences in schooling and experience

premiums to employment in larger establishments evidence from peru abstract examination of the employer size wage effect for males in urban peru suggests the following higher wages in larger establishments do not merely compensate for higher worker quality or inferior working conditions size differences in the use of rising wage tenure profiles cannot provide a market clearing explanation for the employer size wage effect unless workers are extremely impatient thus larger employers appear to pay premiums unionization explains none of the premiums and minimum wage compliance explains at best a small fraction shirking based efficiency wage explanations for premiums are implausible because peruvian job security legislation greatly inhibits dismissals in larger establishments explanations meriting further research involve the use of high wages to reduce turnover and to improve productivity enhancing morale

water on fire gains from electricity trade in light of the ongoing liberalization of electricity trade in the nordic countries and perhaps in northern europe we argue that gains from electricity trade may be different from those traditionally associated with comparative advantages and economies of scale in particular we consider gains arising from the exploitation of technological complementarities between hydro and thermal systems our theoretical framework highlights essential features of the two systems and allows for an analysis of effects of trade we study three trading regimes which may arise either endogenously or because of trade regulations day night power exchange seasonal energy banking and unbalanced trade the analysis suggests that gradual trade liberalization may be costly

union wage differentials in the public and private sectors a simultaneous equations specification the paper attempts to integrate new approaches to estimating union wage effects with the analysis of public private sector wage differentials estimates of the union differential in both public and private sectors allowing for the endogeneity of union status are presented the hypothesis that the recently measured rents to public sector employment primarily reflect the recent increase in unionization in that sector is examined and receives considerable empirical support there was evidence of positive selection into the union sector especially for private sector workers union status appears to be strongly influenced by the expected wage gain from joining the union sector

the effects of public sector hiring and compensation policies on the egyptian labor market this article examines the combined impact of the employment guarantee for graduates and public sector compensation policies on the egyptian labor market besides contributing to an unsustainable rate of growth in the government labor force these policies have encouraged queuing for government jobs contributed to high graduate unemployment rates and reduced the employment of graduates in the private sector despite substantial wage erosion in the public sector in recent years government wages when appropriately corrected for observed heterogeneity and sample selection are on a par with or higher than private sector wages especially for graduates when combined with the more desirable nonwage aspects of government jobs these compensation levels explain the attractiveness of public sector employment to graduates government pay scales are especially advantageous to female secondary school graduates who appear to face considerable discrimination in the private sector

are the economy and the environment decoupling a comparative international study 1960 20051 ecological modernization theory posits that even though economic development harms the environment the magnitude of the harmful link decreases over the course of development in contrast the treadmill of production theory argues that the strong relationship between environmental harms and economic development will remain constant or possibly increase through time to evaluate these competing propositions interactions between economic development and time are used in cross national panel analyses of three measures of carbon dioxide emissions the results vary across the three outcomes as well as between developed and less developed countries providing mixed support for both theoretical perspectives the authors conclude by discussing how both theories could benefit from engaging contemporary research concerning changes within the transnational organization of production and the structure of international trade and how these global shifts influence environment economic development relationships

two ways to success expansion of renewable energies in comparison between germany s federal states abstract expansion of renewable energies is a central pillar of the german energy transition towards a non nuclear renewable system the expansion rate is co determined to a significant degree at the level of the federal states and varies considerably from state to state apart from the existence of natural energy resources and general economic conditions do parties in government play an important role for the development at the state level we consider potentially influential factors in a fuzzy set qualitative comparative analysis fsqca focusing on the expansion of renewable electricity production in all 16 federal german states from 2004 to 2014 as a result two promising ways for accelerated expansion of renewable electricity production can be identified on the one hand a group of economically less developed states have succeeded in promoting expansion and uses it as part of an economic modernization strategy within the economically more developed states however the party political composition of the state governments green party s involvement plays a significant role these results also have implications for other federal countries beyond germany pointing to tailor made policy strategies that consider these specific circumstances

examining the determinants and the spatial nexus of city level co2 emissions in china a dynamic spatial panel analysis of china s cities abstract china now the world s top co2 emitter is facing increasingly pressure to instigate energy saving and emission reduction measures as a result great attention is being paid to the driving forces behind co2 emissions in china literature has to date however tended to exclude the city level due to a scarcity of energy statistics at that scale using gis technology and dynamic spatial panel data models and aided by spatiotemporal modeling that integrates remote sensing data and statistical data this study identifies the determinates and the spatial nexus of co2 emissions at china s city level the results show that the co2 emissions of all of china s cities increased between 1992 and 2013 with the highest co2 emission levels occurring in eastern rather than western or central china in addition an obvious spatial agglomeration effect was observed in city level co2 emissions highlighting the influence cities exert on their neighbors our empirical results also emphasize the influence that factors such as economic growth population the industrialization level capital investment and population density all exert in relation to raising co2 emissions as such the study found little evidence in support of the ekc hypothesis these results further imply that if china persists in its current development pattern the estimated factors will inevitably lead to increased co2 emissions in the long term road density and the traffic coupling factor were in contrast both found to exert strong influences to the mitigation of co2 emissions as such improving the coupling degree between the urban spatial structure of a city and its traffic organization could play an important role in reducing co2 emissions our findings merit attention from chinese policy makers as they shed new light on the path toward developing low carbon cities

the design of reform packages under uncertainty the authors present a model of large scale economic reforms modeled on the transition process in eastern europe with aggregate and individual uncertainty concerning the outcome of reforms the government is assumed to choose the speed and sequencing of reforms the authors compare big bang strategies with gradualist reform packages they show that gradualist reform packages may be easier to get started optimal sequencing of reforms should aim at creating constituencies for further reforms and gradualism may generate a higher investment response because of a lower option value of waiting than would a big bang approach copyright 1995 by american economic association

liquidity constraints as a cause of moonlighting an investigation of whether some workers respond to liquidity constraints by moonlighting is carried out using a unique large data set it is found that workers are more likely to moonlight if 1 they have low current incomes relative to their educational attainment and 2 they plan to purchase a house or a car during the next six months

identifying the impacts of income inequality on co2 emissions empirical evidences from oecd countries and non oecd countries abstract the emergence of environmental quality challenges is rooted in social problems which mainly come from income inequality and power gap income inequality and climate change have been highlighted as hindering the achievement of sustainable development and environmental protection globally though existing literature has estimated the influences of income inequality on co2 emissions relatively little is known about the long run and short run effects from a cross national perspective therefore the aim of this study is to shed light on the long run and short run relationships between income inequality and per capita co2 emissions based on balanced country level panel dataset for 78 countries from 1990 to 2017 in order to understand how a country s economic level affects the link between inequality and co2 emissions this study classified the sample countries into three groups oecd countries low income non oecd countries and high income non oecd countries the fmols and dols model is applied to examine the relationship between the income inequality and per capita co2 emission meanwhile the estimates of an ardl model revealed the long run and short run effects our empirical results indicate that there is a long term cointegration relationship between income inequality and per capita co2 emissions higher income inequality promotes emission reductions in oecd countries and high income non oecd countries while the influences are insignificant in low income non oecd countries in the long run per capita income carbon intensity population size and urbanization were also considered in this study the estimates of an ardl model indicate that whilst income inequality does not have a significant impact on co2 emissions in the short run per capita national income positively affects co2 emissions meaning that income growth will accelerate emissions carbon intensity positively affects co2 emissions in the long term indicating that increased income facilitates increased energy use and emissions but that progress in co2 recycling technology may ultimately reduce emissions neither population size nor urbanization rate exerted any obvious effects on per capita co2 emissions from a policy perspective governments have an onerous task ahead of them in balancing economic efficiency and distributary justice lastly we provide insights for policy makers that in order to realize the goal of emission reductions in the long run it may be best to proceed by making reasonable national income redistribution policies and by adjusting the welfare system

the income inequality and carbon emissions trade off revisited abstract this paper investigates the marginal effect of income inequality on carbon emissions per capita we use a panel consisting of 68 countries over a 50 year period from 1961 to 2010 we report estimates that support the hypothesis that there is a trade off between carbon emissions per capita and income inequality this trade off is not homogeneous across countries and depends upon the level of development measured by income per capita using panel smooth transition regression we find that this relationship is negative for countries with low to moderate income per capita but becomes slightly positive after passing a threshold located around fifteen thousand 2011 us dollars moreover the inequality elasticity of emissions per capita is comparable in magnitude to its income elasticity therefore both inequality and income levels are crucial to define policies to reduce carbon emissions this implies a challenge to policymakers who pursue to reduce both income inequality and carbon emissions

the puzzling pattern of multiple job holding across u s labor markets multiple job holding mjh rates differ substantially across u s regions states and metropolitan areas rates decrease markedly with respect to labor market size these patterns have been largely overlooked despite being relatively fixed over at least the past 20 years this article explores explanations for these persistent differences we account for roughly two thirds of the mean absolute deviation in mjh across local labor markets msas the results suggest that variation in mjh across labor markets is driven by labor market differences in job opportunities and worker preferences most important in explaining variation in mjh are msa industry and occupation structure ancestry shares commute times and to a lesser extent labor market churn

wage rigidity micro and macro evidence on labor market adjustment in the modern sector aggregate data on wages and employment may provide misleading indicators of labor market conditions they may suggest inappropriate wage policies in the face of rising unemployment experienced in many developing countries during the 1980s such increases in unemployment are often attributed to wage rigidities a cursory review of aggregate data for the modern sector in cote d ivoire would support this view suggesting that employment declined during the 1979 84 recession due to an increase in real wages examination of disaggregated data from two labor force censuses of the modern sector however shows that real wages declined for specified classes of labor the work force was characterized by greater education training and experience workers with a given level of attributes received a lower real wage by the end of the recession than before it despite this drop in real wages employment in the modern sector declined

a time series analysis of labour absence in australia the authors find evidence from australian time series data supporting two hypotheses about the determination of labor absence first labor absence modeled in a utility maximizing framework that stresses the opportunity cost of labor absence receives considerable support from the data variables that change the slope and or shift the budget constraint facing workers affect labor absence secondly the authors find tentative evidence that coercive or difficult work environments which apparently affect job satisfaction adversely affect labor absence in particular it appears that labor absence is a leading indicator of a deteriorating industrial relations environment characterized by increased industrial disputation copyright 1989 by mit press

the gini coefficient structure and its application for the evaluation of regional balance development in china abstract the evaluation of balanced regional development should consider not only the economic and ecological benefits but also regional differences a nongrouped gini index is constructed based on a continuous distribution function to evaluate the regionally balanced development of the economy and the environment and the applicability of the method is analyzed given the data characteristics combining the difference in the regional economic base and ecological carrying capacity a multigroup overall gini index mgo gini with regional spatial heterogeneity is further developed along with its decomposition structure this work evaluates and analyses the regional balance in china s development with regard to regional industrial output energy consumption and pollution emissions from 2000 to 2015 using both the nongrouped and the mgo gini the results show that the gini index constructed in this paper can be well adapted to fat tailed data which is a typical feature of china s regional economic and ecological benefits data the regionally balanced development of china does not obviously promote industrial output whereas the regional balance of energy consumption shows the same upward trend when evaluated with both the nongrouped and the mgo gini from 2000 to 2015 in recent years after a period of improvement the regional balance of pollution emissions has experienced a downward trend there is disparity in cleaner production efficiency between regions of china as well as an upward trend in this disparity in recent years china s interregional balance has been enhanced in terms of energy consumption and pollution emissions considering regional spatial heterogeneity whereas the balance of economic output has been further reduced the balance in regional energy consumption plays a supporting role in balanced development among regions the imbalance within developed areas is the main source of regional economic output and energy consumption imbalances and the imbalance in developing areas is the main source of the regional pollution imbalance in china

impact of income inequality and environmental regulation on environmental quality evidence from china abstract china s environmental pollution is of widespread concern and environmental governance has become the country s main method of achieving high quality development environmental quality is a comprehensive indicator which includes many factors such as air water and solid waste pollution this study did not use a single pollutant as a substitute variable for environmental quality firstly we used principal component analysis to construct a comprehensive environmental quality index secondly the stochastic impacts by regression on population affluence and technology and panel quantile regression models were used with data from 30 chinese provinces in china from 1998 to 2017 to analyze the effect of income inequality and environmental regulation on environmental quality the constructed comprehensive index revealed that china s environmental quality had an m type trend over time the mean regression results showed that income inequality and environmental regulation improved environmental quality but higher income inequality reduced environmental quality the panel quantile regression model results revealed that the coefficient of income inequality was positively significant at the 10 30 quantiles and negatively significant at the 70 90 quantiles the coefficients of the absolute value of income inequality at the 10 30 quantiles were less than those at the 70 90 quantiles this implied that higher income inequality reduced environmental quality whereas higher environmental regulations improved environmental quality considering the possible impact of environmental quality on income inequality and environmental regulations we designed a simultaneous equation model to overcome the deviation caused by bilateral causality the conclusions of this study provide policymakers with a new perspective on environmental governance and new paths for achieving high quality development

wage differentials and moonlighting by civil servants evidence from cote d ivoire and peru as part of their efforts to reduce fiscal deficits many governments have allowed public sector salaries to erode often on the assumption that government workers are overpaid vis a vis those in the private sector that assumption is tested by analyzing public private pay differentials in cote d ivoire and peru switching regressions models are estimated using full information maximum likelihood fiml and the results are compared to those obtained using ordinary least squares ols techniques the ols yields seriously biased estimates of the pay structure suggesting that public wages are higher than private wages the fiml estimates show the opposite our probit analysis also shows that the wage disadvantage of civil servants is a determinant of the greater prevalence of moonlighting among public than private employees the evidence suggests that reductions in employment rather than pay while being less palatable in the short term will be more effective in the long run

income inequality and carbon emissions in the united states a state level analysis 1997 2012 abstract this study investigates the relationship between u s state level co 2 emissions and two measures of income inequality the income share of the top 10 and the gini coefficient each of the inequality measures which focus on unique characteristics of income distributions is used to evaluate the arguments of different analytical approaches results of the longitudinal analysis for the 1997 to 2012 period indicate that state level emissions are positively associated with the income share of the top 10 while the effect of the gini coefficient on emissions is non significant the statistically significant relationship between co 2 emissions and the concentration of income among the top 10 is consistent with analytical approaches that focus on political economy dynamics and veblen effects which highlight the potential political and economic power and emulative influence of the wealthy the null effect of the gini coefficient is generally inconsistent with the marginal propensity to emit approach which posits that when incomes become more equally distributed the poor will increase their consumption of energy and other carbon intensive products as they move into the middle class

taxes and bribery the role of wage incentives this paper presents a simple model to evaluate alternative payment schemes for tax inspectors in the presence of corruption we consider problems of both moral hazard which arises because taking bribes cannot be observed without costly monitoring and adverse selection since not all potential tax inspectors can be identified as being honest or dishonest we identify three wage regimes first one could pay the same wage that a tax inspector could earn elsewhere his reservation wage second one could pay a wage which solves the moral hazard problem i e deters bribery this we call an efficiency wage by analogy with recent models examined i n macro economics third the government could pay a wage below the reservation wage at which only the dishonest become tax inspectors the capitulation wage we make precise the conditions under which each yields the greatest amount o f tax revenues net o f administrative costs many countries in the developing world are undergoing structural adjustment programmes which require fundamental fiscal changes outside agencies advise restoration of budget balance a task which involves expenditure cuts and tax increases the treatment of public employee pay scales often poses a particular dilemma i n this process wages and salaries are a significant component of government expenditures and one important question concerns the extent to which wages rather than employment cuts should be used to save money there is sometimes a reluctance to advocate wage cuts stemming in part from a feeling that this might impair the performance of the public sector hence tanzi 1990 argues that a policy of wage cutting is likely to increase the inefficiency of public sector employees especially at a time when the public sector is expected to play a larger role in restructuring the economy p 16 in the context of tax collection the issue is particularly pressing given the need to raise more tax revenues a reduction in efficiency in this branch of the government i s likely t o mean that fewer returns are processed and when individuals living standards are squeezed their incentive to accept bribes in lieu o f collecting taxes i s increased o n this count i t i s even sometimes suggested that wages of tax inspectors should be increased to aid the effort to the comments of henry bienen john hey and two anonymous referees have been helpful in revising this paper the authors are also grateful t o the john m olin program for the study o f economic organization and public policy at princeton university and the pew charitable trusts for financial support mclaren also acknowledges support from the international finance section of princeton university none of the above should be implicated in any way see for example goode 1984 chapter 1 3 and gould and amaro reyes 1983

quantifying the global and distributional aspects of american household carbon footprint abstract analysis of household consumption and its environmental impact remains one of the most important topics in sustainability research nevertheless much past and recent work has focused on domestic national averages neglecting both the growing importance of international trade on household carbon footprint and the variation between households of different income levels and demographics using consumer expenditure surveys and multi country life cycle assessment techniques this paper analyzes the global and distributional aspects of american household carbon footprint we find that due to recently increased international trade 30 of total us household co 2 impact in 2004 occurred outside the us further households vary considerably in their co 2 responsibilities at least a factor of ten difference exists between low and high impact households with total household income and expenditure being the best predictors of both domestic and international portions of the total co 2 impact the global location of emissions which cannot be calculated using standard input output analysis and the variation of household impacts with income have important ramifications for polices designed to lower consumer impacts on climate change such as carbon taxes the effectiveness and fairness of such policies hinges on a proper understanding of how income distributions rebound effects and international trade affect them

public private wage differentials in haiti do public servants earn a rent abstract this study uses a newly collected data set on haiti where data are very limited to assess how individuals are selected into the public vs private sectors and to estimate public private sector wage differentials the central question is whether or not public servants are earning a rent the estimation procedure is an extension of heckman s 1979 sample selection technique to the case where two selection rules generate the sample the procedure first estimates by bivariate probit analysis the probability of employment in the public or private sector and then for those in the public sector the probability of employment in the state owned enterprises soes vs public administration wage functions are then estimated for all three sectors using the inverse mills ratios from reduced form probits selectivity bias is found to exist in one sector soes correction for this bias in the wage equations lowers the wage differentials between the soe and the private sector and the soe and public administration as is clearly demonstrated by the oaxaca decomposition of these estimated mean differentials nevertheless the corrected findings still indicate that the public sector especially the soes earn a sizable rent

emulation inequality and work hours was thorsten veblen right we investigate the manner in which a desire to emulate the rich influences individuals allocation of time between labour and leisure greater inequality inducing longer work hours as a result data on work hours in ten countries over the period 1963 98 show that greater inequality is indeed associated longer work hours these veblen effects are large and the estimates are robust using country fixed effects and other specifications because consumption inequality is a public bad a social welfare optimum cannot be implemented by a flat tax on consumption but may be accomplished by more complicated progressive consumption taxes at the close of the nineteenth century thorsten veblen proposed what he termed pecuniary emulation as the foundation of a theory of consumption spending he maintained is driven by relative status considerations that is by the desire to be a particular type of person as much as bythedesire to enjoytheconsumer goodsper se the joneses with whom one had to keep up were not the neighbours but the rich theirleveloflivingbecamethenever attainableobjectiveinaconsumptionarmsrace among the less well to do in the theory of the leisure class he wrote the motive is emulation the stimulus of an invidious comparison especially in any community in which class distinctions are quite vague all canons and reputability and decency and all standards of consumption are traced back by insensible gradations to the usages and thoughts of the highest social and pecuniary class the wealthy leisure class 1934 p 81 while valued by some economists as capturing common sense aspects of consumption as a form of status seeking veblen s view of social preferences was soon eclipsed by the simpler and more tractable neoclassical theory of the consumer relegated to the underworld of economics veblen s ideas have nonetheless resonated over the ensuing years in the writing of duesenberry 1949 leibenstein 1950 and galbraith 1958 at the middle of the past century and schor 1998

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
