median voters or budget maximizers evidence from school expenditure referenda some readers may have found these results of greater interest were we able to confirm the directional hypotheses of the certainty setter model in addition to finding that spending is related to the reversion the much weaker prediction of the uncertainty model yet the failure of the certainty when base elections were optional their infrequent occurrence might be expected under either a median voter or a setter model for those districts that did hold base elections the observations appear consistent with a setter model but are either inexplicable by or inconsistent with a median voter model finally both a the relationship between the number of budget elections and the presence of base elections and b the outcome of mandatory base elections in 1978 provide a set of observations that are challenging to either model a similar challenge was posed by our investigation of budget elections when we called attention to the inadequacy of static full information models rather than resolving the question of the simple setter model against the simple median voter model our results indicate that both may be inappropriate and that endeavors dealing with complexities omitted here are warranted

testing for asymmetric information in insurance markets the first goal of this paper is to provide a simple and general test of the presence of asymmetric information in contractual relationships within a competitive context we also argue that insurance data are particularly well suited to such empirical investigations to illustrate this claim we use data on contracts and accidents to investigate the extent of asymmetric information in the french market for automobile insurance using various parametric and nonparametric methods we find no evidence for the presence of asymmetric information in this market

price adjustment in long term contracts the case of coal in two recent papers i examined the effects of relationship specific investment on the duration of contracts negotiated between electric utilities and coal suppliers that work demonstrated that when relationshipspecific investment is important for a cost minimizing supply relationship contracts are frequently utilized that specify ex ante the terms and conditions of trade over many future years in this article i examine the characteristics of the price adjustment provisions specified in these long term coal contracts i utilize a sample of about 250 coal contracts to analyze the structure of formal price adjustment provisions in coal contracts in order to determine the factors that affect initial negotiated contract prices and to examine actual transaction price behavior over time there has been much recent theoretical work as well as some related empirical work that has focused on the benefits of long term contracts when relationship specific investments are important 2 there has also been some theoretical work that focuses on the contractual arrangements that may be chosen to mitigate opportunism problems and guard against

political instability corruption and policy formation the case of environmental policy abstract this paper develops a theory of environmental policy formation taking into consideration the degree of corruptibility and political turbulence the predictions that emerge are that the interaction between the two variables is important political instability has a negative effect on the stringency of environmental regulations if the level of corruption is low but a positive effect when the degree of corruption is high corruption reduces the stringency of environmental regulations but the effect disappears as political instability increases the empirical findings are fully consistent with the predictions of the model

has the median voter found a ballot box that he can control this paper examines the appropriateness of the median voter hypothesis within an agenda control framework where the alternative to a proposed expenditure level is the existing level evidence from new york state school districts suggests that within this institutional setting the actual level of public service provision does not differ significantly from the median voter s preferred level the evidence also suggests that demand function parameter estimates for educational expenditures are not sensitive to the assumption that the public service output level corresponds to the median voter s private equilibrium

investigating environmental kuznets curve from an energy intensity perspective empirical evidence from china abstract this study pioneers investigating the environmental kuznets curve ekc hypothesis and its possible regional differential characteristics in china based on 2003 2017 years of provincial panel data this research employs panel smooth transition auto regression pstr model to analyze the impact of income levels on environmental pollution and identify the ekc threshold of energy intensity then 30 chinese provinces were categorized by energy intensity to examine the inter provincial and interregional differences in the ekc threshold of energy intensity rather than the traditional threshold of income the results indicate that china s pollution emissions and energy intensities show a stepwise decreasing pattern from the western region to the eastern region in addition the impact of income levels on pollution emissions is non linear and the critical value of energy intensity is 0 9168 between the high and low regimes an inverted u shaped environmental kuznets curve is accepted for energy intensity with 0 7670 as its threshold value when the energy intensity is higher lower than the threshold value the income elasticity of pollution emission is positive negative the more developed provinces and municipalities mainly in the eastern region are proved to exceed the threshold than the provinces in the central and western regions within the sample period given these findings this study further divides china s provinces into eco friendly low pollution and high pollution provinces and accordingly the most important policy recommendations were discussed for policy makers and researchers this research can provide a new insight to investigate countries with unbalanced development levels within and a reference for environmental governance policies in sub regions

industrial pollution in economic development the environmental kuznets curve revisited abstract using new international data this paper tests the environmental kuznets curve ekc hypothesis for industrial water pollution we measure the effect of income growth on three determinants of pollution the share of industry in national output the share of polluting sectors in industrial output and end of pipe eop pollution intensities per unit of output in the polluting sectors we find that the industry share of national output follows a kuznets type trajectory but the other two determinants do not when combined our results imply rejection of the ekc hypothesis for industrial water pollution it rises rapidly through middle income status and remains roughly constant thereafter

endogenizing the median voter public choice goes to school this paper investigates implications of the relationship between voter self selection and the behavior of politicians voter self selection arises in elections because only a portion of eligible voters actually vote it is likely to be more pronounced whenever the implied net benefits from a given electoral choice are disproportionately distributed across voters public choice theory predicts that incumbent officials will manipulate this self election pursuant to the maximization of their personal objective functions this paper provides evidence from school bond elections that politicians influence voter self selection via manipulation of election parameters

is there a leviathan in your neighborhood this paper measures effects of decentralization in local government hierarchies on local public sector size this sector shrinks if decentralization encourages competition among governments it expands if decentralization sacrifices scale economies in a sample of 3 022 counties larger county governments reduce competition and increase aggregate local public sector size relative to aggregate county income more cities and towns increase competition and reduce its size more special and school districts sacrifice scale economies and increase it two recent articles have attempted to identify the effects of decentralization in state and local government on the size of the state and local public sector wallace oates 1985 finds no important effects michael nelson 1987 finds modest evidence that increased competition among government units reduces the size of the public sector this article demonstrates that the effects of decentralization are important and complex decentralization which encourages competition reduces the size of the local public sector decentralization which discourages scale economies increases it

the hidden economy as an unobserved variable abstract the technique of unobserved variables is used to estimate the relative size and development time of the hidden economy of oecd countries the burdens of taxation and regulations and the tax morality turn out to be statistically significant determinants at the end of the scandinavian and benc lux countries are expected to have a relatively large and japan and switzerland a relatively small hidden economy canada and the united states are rank in the middle the size of all hidden sectors is estimated to have increased in the period 1960 1973 relative to officially measured gnp

political institutions and financial development an empirical study summary this paper examines whether political institutional improvement promotes financial development using a panel dataset of 90 developed and developing countries over 1960 99 the empirical evidence reveals a positive effect of institutional improvement on financial development at least in the short run particularly for lower income countries the preliminary evidence by a before after event study indicates that a democratic transformation is typically followed by an increase in financial development

financial contracting under imperfect enforcement we develop a model ofnancial contracting under imperfect enforcement financial contracts are designed to keep entrepreneurs from diverting project returns but enforce ment is probabilistic and penalties are limited the model rationalizes the prevalence of straight debt and common stock and its predictions are consistent with a host of empirical capital structure regularities across countries acrossrms and across time

interrelationships between income health and the environment extending the environmental kuznets curve hypothesis abstract this paper examines the link between the health indicators and the environmental variables for a cross section of countries widely dispersed on the economic development spectrum while environment and income are seen to have an inverted u shaped relationship environmental kuznets curve ekc hypothesis it is also well established that environment and health are positively related our study focuses on the implications of this for the relationship between health and income in the early phases of income growth the gains in health and the losses in environmental quality could cancel each other out and this challenges the idea that as incomes increase health would always improve to empirically analyse these issues we estimate a two stage least squares model that focuses on the impact of income and the environment on health status with environment being an endogenous variable our results show that the environmental stress variable has a significant negative effect on health status at the same time gross national product gnp levels are shown to vary positively with health status variables we find that the health gains obtained through improved incomes can be negated to a significant extent if the indirect effect of income acting via the environment is ignored research findings in this regard would be a useful policy instrument towards maximising both the environmental and health gains that come with economic growth and development

political economy of public education non college bound students my previous research showed that two important changes in the political environment of public schools growing teacher unionization and a shift of funding responsibility to state governments adversely affected the performance of college bound students here i show similar impacts for public school students who do not go to college these effects are found in analyses of 1971 91 changes in a school performance measure derived from individual scores on the armed forces qualifying test comparative analysis of performance trends in different areas of the same state suggests that the adverse performance effects of teacher unionization and spending centralization stem from their impact on state educational policy rather than on the direct operation of schools these adverse effects are also found for students in the lower tail of achievement and for black students they are not plausibly related to broader political and social changes

an alternate test of the tiebout hypothesis this paper has presented an indirect test of the tiebout hypothesis that does not require explicit consideration of the interaction between the markets for housing and local public services the results suggest that at least in the case of elementary and secondary education when allowed to choose from a selection of jurisdictions individuals locate so as to minimize the allocative inefficiency that results from collective provision of local services

subjective performance measures in optimal incentive contracts objective measures of performance are seldom perfect in response incentive contracts often include important subjective components that mitigate incentive distortions caused by imperfect objective measures this paper explores the combined use of subjective and objective performance measures in respectively implicit and explicit incentive contracts naturally objective and subjective measures often are substitutes sometimes strikingly so we show that if objective measures are sufficiently close to perfect then no implicit contracts are feasible because the firm s fallback position after reneging on an implicit contract is too attractive we also show however that objective and subjective measures can reinforce each other if objective measures become more accurate then in some circumstances the optimal contract puts more weight on subjective measures because the improved objective measures increase the value of the ongoing relationship and so reduce the firm s incentive to renege we also analyze the use of subjective weights on objective performance measures and provide case study evidence consistent with our analyses

relational contracts and the theory of the firm relational contracts informal agreements sustained by the value of future relationships are prevalent within and between firms we develop repeated game models showing why and how relational contracts within firms vertical integration differ from those between nonintegration we show that integration affects the parties temptations to renege on a given relational contract and hence affects the best relational contract the parties can sustain in this sense the integration decision can be an instrument in the service of the parties relationship our approach also has implications for joint ventures alliances and networks and for the role of management within and between firms

the effect of the expansion of the voting franchise on the size of government this paper examines the claim that expansion of the voting franchise has been an important factor in the growth of government state government spending and state and local spending are explained using a panel of 46 states for 1950 88 elimination of poll taxes and literacy tests led to higher turnout particularly among the poor and a poorer pivotal voter as predicted we find that these changes a fall in the income of voters relative to state income and the ouster of republicans from state government led to a sharp rise in welfare spending but no change in other spending

strategic default in the international coffee market this article studies strategic default on forward sale contracts in the international coffee market to test for strategic default we construct contract specific measures of unanticipated changes in market conditions by comparing spot prices at maturity with the relevant futures prices at the contracting date unanticipated rises in market prices increase defaults on fixed price contracts but not on price indexed ones we isolate strategic default by focusing on unanticipated rises at the time of delivery after production decisions are sunk and suppliers have been paid estimates suggest that roughly half of the observed defaults are strategic we model how strategic default introduces a trade off between insurance and counterparty risk relative to indexed contracts fixed price contracts insure against price swings but create incentives to default when market conditions change a model calibration suggests that the possibility of strategic default causes 15 8 average losses in output significant dispersion in the marginal product of capital and sizable negative externalities on supplying farmers

the effects of environmental regulation and technical progress on co2 kuznets curve an evidence from china based on environmental kuznets curve theory a panel data model which takes environmental regulation and technical progress as its moderating factors was developed to analyse the institutional and technical factors that affect the path of low carbon economic development the results indicated that there was a co2 emission kuznets curve seen in china environmental regulation had a significant moderating effect on the curve and the inflection of co2 emissions could come substantially earlier under stricter environmental regulation meanwhile the impact of technical progress on the low carbon economic development path had a longer hysteresis effect but restrained co2 emission during its increasing stage and accelerated its downward trend during the decreasing stage which was conducive to emission reduction strict environmental regulation could force the high carbon emitting industries to transfer from the eastern regions to the central or the western regions of china which would make the co2 kuznets curve higher in its increasing stage and lower in its decreasing stage than that under looser regulation furthermore energy efficiency energy structure and industrial structure exerted a significant direct impact on co2 emissions we should consider the above factors as essential in the quest for low carbon economic development

budget referendums and government spending evidence from swiss cantons vortrag im forschungsseminar der wirtschaftswissenschaftlichen fakultat der universitat basel schweiz am 20 november 2000

toward a new conception of the environment competitiveness relationship accepting a fixed trade off between environmental regulation and competitiveness unnecessarily raises costs and slows down environmental progress studies finding high environmental compliance costs have traditionally focused on static cost impacts ignoring any offsetting productivity benefits from innovation they typically overestimated compliance costs neglected innovation offsets and disregarded the affected industry s initial competitiveness rather than simply adding to cost properly crafted environmental standards can trigger innovation offsets allowing companies to improve their resource productivity shifting the debate from pollution control to pollution prevention was a step forward it is now necessary to make the next step and focus on resource productivity

the decline in the number of school districts in the u s 1950 1980 between 1950 and 1980 the number of school districts fell from 83 642 to 15 987 data for the fifty states for 1950 1960 1970 and 1980 are used to identify the factors that contributed to this decline the focus is on the tradeoff between cost savings through scale economies a few large districts and a diverse population s demand for choice in public schooling many small districts we find that much of the decline in the number of school districts has resulted from 1 the decline in the farm population and increase in population density which has made it easier to take advantage of scale economies 2 the growing importance of state aid which reduces quality variation among districts within a state and 3 the increase in the fraction of teachers that belong to the national education association teacher s union which may reflect increased political influence used to lower the costs of organizing

the public choice of educational choice the very small literature explaining i how citizens have voted in two california voucher referenda ii how legislators have voted on voucher bills in the state of florida and the us congress and iii the variation across states in charter school provisions is summarized new empirical evidence documenting the cross state variation in the success of voucher referenda and voucher bills is examined voucher bill characteristics and state characteristics play important roles voucher bills have been passed only in the more conservative republican states and almost all of the successful voucher programs have been targeted at large struggling school districts

evidence on voter preferences from unrestricted choice referendums from 1939 to 1968 florida used a unique referendum system to set property tax rates for public school operating expenditures at the median millage rate selected by voters these referendums revealed the entire distribution of voter preferences which is not possible in the standard up or down referendum we are the first to use the florida referendum data the form of the ballot played an important role in how people voted voting machine elections were much more likely than paper ballots to result in rejections of the recommendations of school boards and produced much greater dispersion of expressed preferences

corruption and the shadow economy an empirical analysis this paper analyzes the influence of the shadow economy on corruption and vice versa we hypothesize that corruption and the shadow economy are substitutes in high income countries while they are complements in low income countries the hypotheses are tested for a cross section of 98 countries our results show that there is no robust relationship between corruption and the size of the shadow economy when perceptions based indices of corruption are used employing an index of corruption based on a structural model however corruption and the shadow economy are complements in countries with low income but not in high income countries

dynamic incentives of environmental regulations the effects of alternative policy instruments on technology diffusion abstract we develop a framework for comparing empirically the effects of alternative environmental policy instruments on the diffusion of new technology market based and command and control approaches can he quantitatively compared by estimating the economic penalty that firms through their actions reveal to be associated with violation of standards in the context of concerns about global climate change we empirically examine the likely effects of pigouvian taxes technology adoption subsidies and technology standards we employ state level data on the diffusion of thermal insulation in new home construction comparing the effects of energy prices insulation cost and building codes

an analysis of the principal agent problem most analyses of the principal agent problem assume that the principal chooses an incentive scheme to maximize expected utility subject to the agent s utility being at a stationary point an important paper of mirrlees has shown that this approach is generally invalid we present an alternative procedure if the agent s preferences over income lotteries are independent of action we show that the optimal way of implementing an action by the agent can be found by solving a convex programming problem we use this to characterize the optimal incentive scheme and to analyze the determinants of the seriousness of an incentive problem

a model of optimal plant size with an application to the demand for cognitive achievement and for school size a model of optimal plant size is developed which predicts that 1 plants experience increasing returns to in plants inputs 2 the relative price of plant output is greater in rural areas than in urban areas and 3 plants are larger in urban areas than in rural areas the model s predictions appear to be consistent with behavior in a number of consumer services e g grocery movie and library services these predictions are more rigorously tested and are strongly supported when demand functions for cognitive achievement and for school size are estimated these regressions also lend support to the quality quantity model of fertility

the economics of schooling production and efficiency in public schools n recent years public and professional interest in schools has been heightened by a spate of reports many of them critical of current school policy these policy documents have added to persistent and long standing concerns about the cost effectiveness and fairness of the current school structure and have made schooling once again a serious public issue as in the past however any renewed interest in education is likely to be short lived doomed to dissipate as frustration over the inability of policy to improve school practice sets in this frustration about school policy relates directly to knowledge about the educational production process and in turn to underlying research on schools although the educational process has been extensively researched clear policy prescriptions flowing from this research have been difficult to derive 2 there exists however a consistency to the research findings that does have an immediate application to school policy schools differ dramatically in quality

in kind finance a theory of trade credit it is typically less profitable for an opportunistic borrower to divert inputs than to divert cash therefore suppliers may lend more liberally than banks this simple argument is at the core of our contract theoretic model of trade credit in competitive markets the model implies that trade credit and bank credit can be either complements or substitutes among other things the model explains why trade credit has short maturity why trade credit is more prevalent in less developed credit markets and why accounts payable of large unrated firms are more countercyclical than those of small firms

the determinants of attitudes towards strategic default on mortgages we use survey data to measure households propensity to default on mortgages even if they can afford to pay them strategic default when the value of the mortgage exceeds the value of the house the willingness to default increases in both the absolute and the relative size of the home equity shortfall our evidence suggests that this willingness is affected by both pecuniary and non pecuniary factors such as views about fairness and morality we also find that exposure to other people who strategically defaulted increases the propensity to default strategically because it conveys information about the probability of being sued

pollution shadow economy and corruption theory and evidence abstract we study how the shadow economy affects pollution and how this effect depends on corruption levels in public administration production in the shadow economy allows firms to avoid environmental regulation policies a large informal sector may be accompanied by higher pollution levels our theoretical model predicts that controlling the levels of corruption can limit the effect of the shadow economy on pollution we use panel data covering the period from 1999 to 2005 in more than 100 countries to test this theoretical prediction our estimates confirm that the relationship between the shadow economy and the levels of pollution are dependent on the levels of corruption our results hold when we control for the effects of other determinants of pollution time varying common shocks country fixed effects and various additional covariates

observing unobservables identifying information asymmetries with a consumer credit field experiment information asymmetries are important in theory but difficult to identify in practice we estimate the presence and importance of hidden information and hidden action problems in a consumer credit market using a new field experiment methodology we randomized 58 000 direct mail offers to former clients of a major south african lender along three dimensions i an initial offer interest rate featured on a direct mail solicitation ii a contract interest rate that was revealed only after a borrower agreed to the initial offer rate and ii a dynamic repayment incentive that was also a surprise and extended preferential pricing on future loans to borrowers who remained in good standing these three randomizations combined with complete knowledge of the lender s information set permit identification of specific types of private information problems our setup distinguishes hidden information effects from selection on the offer rate via unobservable risk and anticipated effort from hidden action effects via moral hazard in effort induced by actual contract terms we find strong evidence of moral hazard and weaker evidence of hidden information problems a rough estimate suggests that perhaps 13 to 21 of default is due to moral hazard asymmetric information thus may help explain the prevalence of credit constraints even in a market that specializes in financing high risk borrowers

does restricting choice in referenda enable governments to spend more if school boards represent the preferences of the median voter referendums to approve school expenditures should not constrain school expenditures if school boards would choose expenditures larger than the median voter s preference referendums that restrict voters to approving or disapproving a school board s recommended expenditure level will result in expenditures larger than the median voter would prefer however florida used a unique referendum system which guaranteed the median voter s most preferred outcome using florida education expenditures as a benchmark the evidence suggests that spending was slightly higher in restricted choice referendum states than in florida

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

searching for leviathan comment and extension in a recent article wallace oates 1985 investigated whether fiscal decentralization tended to act as a constraining influence on the overall size of the public sector this hypothesis has been advanced by several alternative theories of government behavior including richard musgrave s 1959 model of how the distribution function of government would be carried out by subnational governments geoffrey brennan and james buchanan s 1980 leviathan model and the more traditional public choice model for example walter hettich and stanley winer 1984 all contend that the decentralization of tax and spending decisions introduces competition among governmental units seeking to attract citizens and other mobile resources and thereby constrains taxing power oates analyzed two data sets one pertaining to the state and local sector in the united states and the other consisting of a sample of 43 countries and found little empirical support for the decentralization hypothesis the purpose of this paper is to reconsider his analysis in the case of state and local governments specifically it will be argued that oates s measures of decentralization may be inappropriate to test the hypothesis furthermore by taking into account the structure or composition of local governmental jurisdictions within a state empirical support of the decentralization hypothesis can be marshaled for general purpose local governments such as counties and municipalities i measuring fiscal decentralization among the states

why hold ups occur the self enforcing range of contractual relationships one of my most enjoyable intellectual experiences was working with armen alchian on the klein crawford and alchian 1978 hold up paper in this paper i extend the basic framework presented in that paper pointing out what i now consider to be its shortcomings and providing insights into the nature of hold ups and the form of contracts chosen by transactors to avoid hold ups the major analytical extension entails combining hold up analysis with my work on private enforcement because private enforcement capital is limited and written contract terms are necessarily imperfect transactors must optimally combine court enforced written terms together with privately enforced unwritten terms to define what i call the self enforcing range of their contractual relationship hold ups occur when unanticipated events place the contractual relationship outside the self enforcing range this probabilistic framework where transactors enter contractual relationships knowing that a hold up may take place but believing that the expected gains from trade outweigh the expected rent dissipating costs associated with the hold up risk is shown to have important implications for understanding the structure of contracts adopted by transactors in the marketplace i why do hold ups occur i begin with a simple example that illustrates the basic economic forces involved in a hold up assume that a builder constructs a house on a piece of land the builder does not own but rather only leases short term after the initial land lease expires the landowner could hold up the builder by raising the land rent to reflect the costs of moving the house to another lot this example illustrates all the hold up factors emphasized in klein crawford and alchian a the builder has made an investment that is highly specific to a particular piece of land and b the landowner has taken advantage of the incompleteness of the contract that governs the relationship in particular the fact that the lease does not cover future years to c expropriate the quasi rents on the builder s specific investment the obvious question is why anything like this would ever occur that is why would someone be so naive as to build a house on land for which they had only a short term lease our primary goal in klein crawford and alchian was not to explain the existence of hold ups but rather the institutions adopted by transactors to avoid hold ups for example we would expect that builders anticipating a potential hold up problem would decide to purchase the land or at least to sign a long term ground lease before starting construction however we do present some examples in the paper of hold ups that actually occurred the implicit reason we give for the occurrence of these hold ups is transactor ignorance apparently transactors are not always smart enough to choose the contractual arrangement that would eliminate the hold up problem oliver williamson provides a similar but much more explicit answer to the question of why hold ups occur when defining opportunism he states by opportunism i mean self interest seeking with guile this includes but is scarcely limited to more blatant forms such as lying stealing and cheating opportunism more often involves subtle forms of deceit more generally opportunism refers to the incomplete or distorted disclosure of information especially to calculated efforts to mislead distort obfuscate or otherwise confuse 1 for example the hold up may have occurred in our illustrative house construction example because the landowner deceived the builder with a low up front land rental price and vague promises about the future relying on the ability of one transactor to take advantage of the naivete or ignorance of another transactor is a highly unsatisfactory way to explain the incidence of hold ups simple examples of deception such as a builder constructing a house on land that is only rented short term rarely if ever occur

environmental kuznets curve in china new evidence from dynamic panel analysis this paper applies a panel of 28 provinces of china from 1996 to 2012 to study the impacts of economic development energy consumption trade openness and urbanization on the carbon dioxide waste water and waste solid emissions by estimating a dynamic panel model with the system generalized method of moments gmm estimator and an autoregressive distributed lag ardl model with alternative panel estimators respectively we find that the environmental kuznets curve ekc hypothesis is well supported for all three major pollutant emissions in china across different models and estimation methods our study also confirms positive effects of energy consumption on various pollutant emissions in addition we find some evidence that trade and urbanization may deteriorate environmental quality in the long run albeit not in the short run from policy perspective our estimation results bode well for chinese government s goal of capping greenhouse emissions by 2030 as outlined in the recent china us climate accord while containing energy consumption and harm effects from expanding trade and urbanization remains some environmental challenges that china faces

the political economy of benefits and costs a neoclassical approach to distributive politics this essay offers a rational political explanation for the notorious inefficiency of pork barrel projects with an optimization model of legislative behavior and legislative institutions the model emphasizes the economically arbitrary from a welfare point of view importance of the geographic incidence of benefits and costs owing to the geographic basis for political representation we explore the implications of a legislator s objective function and derive conditions under which a representative legislature will select an omnibus of projects each of which exceeds the efficient scale

evidence on the impact of state government on primary and secondary education and the equity efficiency trade off abstract state governments may affect the productivity of primary and secondary education in two ways first various regulations imposed on local school districts are expected to make schools less efficient second state efforts to reduce inequality in education spending make it more difficult for voters to increase school quality which should lead to less voter monitoring of schools and thus less efficient schools our empirical analysis of state scholastic aptitude test sat scores from 1987 to 1992 provides evidence on both effects the state s revenue share which captures state meddling in local decisions has the expected negative impact on school efficiency but our novel result is that state induced spending equalization also lowers average test scores but has had little if any effect on reducing the disparity in student achievement these results bring into question policy efforts designed to shift education responsibilities from local governments to state and federal governments

determinants of pollution abatement in developing countries evidence from south and southeast asia abstract developing countries pa ticularly those in asia are fast adopting industrial pollution control standards similar to those in developed countries formal regulation has been greatly hampered however by the absence of clear and legally binding regulations limited institutional capacity lack of appropriate equipment and trained personnel and inadequate information on emissions one would predict highly pollution intensive production under such conditions our research however has uncovered strongly contradictory evidence despite weak or nonexistent formal regulation there are many clean plants in the developing countries of south and southeast asia of course there are also many plants which are among the world s most serious polluters what explains such extreme interplant variation this paper reviews evidence drawn from three empirical studies of plant level abatement practices conducted 1992 1994 the analyses test the importance of plant characteristics economic considerations and external pressure in determining environmental performance the results consistently show that pollution intensity is negatively associated with scale productive efficiency and the use of new process technology it is strongly and positively associated with public ownership but foreign ownership has no significant effect once other plant characteristics are taken into account among external sources of pressure community action or informal regulation emerges as a clear source of interplant differences in all three studies the results suggest that local income and education are powerful predictors of the effectiveness of informal regulation they also show that existing formal regulation has measurably beneficial effects even when it is quite weakly developed

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 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

the median voter model in public choice theory the changing perception by public choice theorists about the relevance of the median voter model is a result of excessive extrapolation of the conclusions of theoretical models to the real world early in the 1970s the median voter model was often accepted as implying that the output produced in the public sector was what was most preferred by the median voter this claim is excessive because the median voter model is only a model of demand aggregation under majority rule and has little to say about the supply side of the public sector in the late 1970s many scholars identified several circumstances under which the model would not apply in theory but these critiques of the model were often viewed as reasons to abandon the median voter model altogether the model went from having excessive claims that made the model appear to be more powerful than it really is to excessive claims that made the model appear to be less powerful than it really is these latter claims were often in response to the earlier claims rather than to the model appropriately applied

the environmental consequences of domestic and foreign investment evidence from china abstract fixed asset investment fai and foreign indirect investment fdi have important influences on economic development and environmental quality because environmental performance is related with economic development fai and fdi may affect environment indirectly through their impacts on economic growth in this study the direct and indirect effects of both fai and fdi on china s environmental quality are distinguished and separately estimated for the first time with a carefully designed framework of a two equation model because most economic activities and environmental pollutions occur in the urban areas a panel data of 112 chinese cities for the period 2002 2015 is utilized several spatial factors are also introduced to control for the potential spatial correlations in economic development and pollutant emissions the estimation results indicate that there exist apparent differences in the environmental effects of fai and fdi the direct effects of fai on so 2 emissions are significant positive and dominate the negative indirect effects by contrast the direct indirect and total effects of fdi on pollutant emissions are all negative therefore overall speaking well designed and targeted policies should be formulated to reduce the negative environmental impacts of fai and to increase the positive influences of fdi on environment

the choice of municipal government structure and public expenditures numerous empirical studies have attempted to measure the effect of varying government structures on public expenditures i argue that these prior may have produced biased estimates as they are predicated on the assumption that government structures are exogenous

competition and relational contracts in the rwanda coffee chain how does competition affect market outcomes when formal contracts are not enforceable and parties resort to relational contracts difficulties with measuring relational contracts and dealing with the endogeneity of competition have frustrated attempts to answer this question we make progress by studying relational contracts between upstream farmers and downstream mills in rwanda s coffee industry first we identify salient dimensions of their relational contracts and measure them through an original survey of mills and farmers second we take advantage of an engineering model for the optimal placement of mills to construct an instrument that isolates geographically determined variation in competition conditional on the suitability for mills placement within the catchment area we find that mills surrounded by more suitable areas i face more competition from other mills ii use fewer relational contracts with farmers and iii exhibit worse performance an additional competing mill also iv reduces the aggregate quantity of coffee supplied to mills by farmers and v makes farmers worse off competition hampers relational contracts directly by increasing farmers temptation to default on the relational contract and indirectly by reducing mill s profits

impact of corruption in public sector on environmental quality implications for sustainability in brics and next 11 countries abstract this study investigates the impact of corruption in public sector on carbon emissions in presence of energy use segregation following the environmental kuznets curve ekc framework the study has been carried out for brazil russia india china south africa brics and next 11 countries over the period of 1990 2017 along with the finding of inverted n shaped ekc for both the cases we find that incidents of corruption enhance environmental degradation by reducing the positive impact of renewable energy consumption on environmental quality and increasing the negative impact of fossil fuel consumption this study has also divulged that the corruptive practices are more prone in case of the countries where the development is mature and institutionalization is more stringent based on these findings we suggest that environmental policies should take account of the corruption and thereby making the policies more robust and effective

is there convergence in per capita so2 emissions in china an empirical study using city level panel data abstract as china s economy has grown rapidly in recent years china s environmental pollution has become increasingly significant among all the traditional pollutants sulfur dioxide has been monitored by the chinese government since the 1990s in this study china s city level panel data between 2002 and 2012 are utilized to investigate the existence of convergence in per capita sulfur dioxide emissions across chinese cities the conventional estimation methods for convergence suffer from an endogeneity problem and therefore produce biased results to address the endogeneity problem and allow for dynamics dynamic panel data estimators are utilized and the static estimation results are conducted as a robustness check in addition the influential factors for convergence are examined the empirical results indicate that in the chosen sample period there were absolute and conditional convergences in per capita sulfur dioxide emissions across cities within the whole nation as well as in the eastern western and central regions of china because per capita gross domestic product and the ratio of secondary industry to gross domestic product are both positively related with per capita sulfur dioxide emissions higher income per capita and greater importance of the secondary industry would cause the convergence speed to be lower therefore the most straightforward policy implication for the empirical results is that the policies for controlling sulfur dioxide emissions should be regionally differentiated for cities with high sulfur dioxide emissions per capita the regulation could be tight as the emissions would decrease faster because convergence exists however for cities with low sulfur dioxide emissions per capita the target for reducing emissions should not be excessively aggressive

unionization and cost of production compensation productivity and factor use effects unionization affects cost of production through compensation premia technology shifts and deviations from the least cost combination of inputs the first two are familiar but the last is not this article distinguishes the three effects illustrates the factor use effect and suggests that it may resolve several apparent inconsistencies union induced cost effects appear larger than those implied by union compensation and productivity differentials union compensation and productivity differentials suggest a larger effect on labor intensity of output than is observed and employers complain that union work rules reduce productivity when there is little evidence that this is so

the legacy of serrano the impact of mandated equal spending on private school enrollment 1 introduction the california supreme court decision in serrano v priest in 1971 was the first state supreme court ruling to declare a state s education finance system unconstitutional 1 the suit originally filed by a class of los angeles county public school children and their parents argued that the california public school finance system was unconstitutional because of its reliance on a local property tax system under this system large differences in property wealth created enormous variations in educational resources across the state in its subsequent 1976 serrano h decision the california supreme court found that the state legislature s response to the first serrano decision was insufficient the court ordered the state legislature to follow a trial court s requirement to implement a funding formula that reduces wealth related per pupil expenditure disparities i e property tax revenue exclusive of categorical aid and special needs to 100 across school districts the serrano ii decision resulted in a nearly complete shift of the fiscal responsibility for k 12 education in california from local to state government in the aftermath of the initial serrano decision suits were filed in several other states claiming unconstitutional inequities in the state education system many of these suits were successful between 1973 and 1983 six state supreme courts new jersey 1973 connecticut 1977 washington 1978 west virginia 1979 wyoming 1980 arkansas 1983 found their systems of educational finance unconstitutional similar rulings followed in 1989 in kentucky montana and texas in 1993 in massachusetts and tennessee in 1994 in arizona and in 1997 in new hampshire ohio and vermont a third of the states education finance systems now have been ruled unconstitutional as a result of these rulings and legislative based education reforms in a number of other states education expenditure inequality has been reduced 2 this in turn has left local districts with less latitude in determining spending levels parents in richer districts are expected to be especially frustrated with the limits on spending that accompany equalization changes in state educational finance systems to gain greater equity affected average spending on education in these states the initial research on this issue focused on the california experience where raw expenditure figures reveal the dramatic change in per pupil spending in california since the initial serrano decision in 1971 in academic year ay 1969 1970 per pupil spending in california s public elementary and secondary schools was slightly greater than the national average 106 25 of the national average ranking 14th among all states however by ay 1992 1993 education expenditures in california had fallen to 85 6 of the national average and its rank had dropped to 34th silva and sonstelie 1995 concluded that education spending in california in 1989 1990 was significantly lower than they would have otherwise predicted they attributed about half of the lowered spending to the legislation following serrano ii and the other half to the growth of the student population in california but the california experience of reduced expenditures appears to be atypical manwaring and sheffrin 1997 found spending to be higher in many states as a result of litigation or legislativebased educational finance reform downes and shah 1995 similarly estimated that school finance reform raised spending in some states and lowered spending in other states murray evans and schwab 1998 found state per pupil spending rose with successful state education finance litigation the variation across states in the spending effects of education finance reforms may be due to the source court ordered or legislative and or degree e g weak reform strong reform etc of the reforms in any case there should be greater interest in supplementing what the public schools do or opting out of the public system if reforms cause spending in a state to fall

fair trade and free entry can a disequilibrium market serve as a development tool abstract the fair trade ft coffee initiative attempts to channel charity from consumers to poor producers via increased prices we show that the rules of the ft system permit this rent to be eliminated due to free entry and costly excess certification of output using data from an association of coffee cooperatives in central america we verify that expected producer benefits are close to 0 when we take into account the output that is certified but not sold as ft our results illustrate how free entry undermines the attempt at extending charity via a price distortion in an otherwise competitive market

liquidity constraints and imperfect information in subprime lending ditions for precisely the population that is most likely to have a difficult time obtaining credit those with low incomes and poor credit histories these consumers who typically cannot qualify for regular bank loans comprise the so called subprime market because the company we study originates subprime loans its loan applications and transaction records provide an unusual win dow into the consumption and borrowing behavior of households that are rationed in primary credit markets moreover we track loan repayments allowing us to analyze the difficulties in lending to the subprime population we begin by documenting the importance of short term liquidity constraints for individuals in our sample we present two pieces of evidence both are based on purchasing behavior and indicate a high sensitivity to cash on hand first we document a dramatic degree of demand seasonality associated with tax rebates overall demand is almost 50 percent higher during tax rebate season than during other parts of the year this seasonal effect varies with household

the dynamic relationship between environmental pollution economic development and public health evidence from china abstract during the last two decades of rapid economic growth china s environmental pollution has become increasingly serious and the corresponding health damage has become a significant problem that has attracted domestic and foreign attention as china pursues sustainable economic growth the issues of environmental degradation and public health should be well addressed using sulfur dioxide emissions wastewater emissions and soot and dust emissions as indicators of environmental quality this study investigates the comprehensive dynamic relationship between environmental quality economic development and public health in china for the first time to control for potential endogeneity this paper utilizes a carefully designed simultaneous equation model sem that is composed of three equations that describe the relationships among economic development environmental quality and public health using panel data from 30 chinese provinces for the period from y2002 to y2014 the model verified the negative effect of environmental pollution on public health moreover economic and social factors may also affect public health for instance real gdp per capita has a significant negative impact on perinatal mortality rates and education and medical conditions also contribute significantly to promoting economic growth and improving the level of public health

optimal contracts under costly state falsification we examine an exchange economy with two agents one risk neutral with a certain endowment and a second risk averse with a random endowment the realization of the endowment is public but can be falsified by the second agent at a cost for a broad class of falsification cost functions the optimal no falsification contract is noncontingent on a left hand interval and strictly increasing with a slope strictly less than one on a right hand interval under a mild further restriction optimal no falsification contracts are in addition piece wise linear optimal contracts may in general require falsifying the state but for a set of the highest endowment realizations there is no falsification we find simple conditions under which the optimal contract is a no falsification contract the model has applications that include financial insurance and employment contracts and tax policy

the determination of local public expenditures and the principal and agent relation a case study the principal and agent relationship is important in the public sector there elected or appointed representatives act on behalf of the citizens of their jurisdictions this paper examines the importance of the budget referendum which allows the principals to approve or disapprove the proposal of a set of agents in the context of local public expenditure decisions we test the null hypothesis that the institution of referendum when compared to a nonreferendum institution does not lead to significantly different expenditure behavior

economic structure development policy and environmental quality an empirical analysis of environmental kuznets curves with chinese municipal data in many cases the relationship between environmental pollution and economic development can be generally depicted by an inverted u shaped curve or an environmental kuznets curve where pollution increases with income at the beginning and decreases after a certain level of income however what determine the shape of an enviornmental kuznets curve such as the height and the turning point of the curve have not been thoroughly studied a good understanding of the determinants is vitally important to the development community especially for the developing world where income growth is a high priority and yet environmental pollution also needs to be carefully controlled this study analyzes the impacts of economic structure development strategy and environmental regulation on the shape of the environmental kuznets curve with a city level panel dataset obtained from china the results show that economic structure development strategy and environmental regulation can all have important implications on the relationship between environmental environmental quality and economic development but the impacts can be different at different development stages

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

energy consumption carbon emissions and economic growth in china abstract this paper investigates the existence and direction of granger causality between economic growth energy consumption and carbon emissions in china applying a multivariate model of economic growth energy use carbon emissions capital and urban population empirical results for china over the period 1960 2007 suggest a unidirectional granger causality running from gdp to energy consumption and a unidirectional granger causality running from energy consumption to carbon emissions in the long run evidence shows that neither carbon emissions nor energy consumption leads economic growth therefore the government of china can purse conservative energy policy and carbon emissions reduction policy in the long run without impeding economic growth

environmental productivity and kuznets curve in india abstract as a result of india s extremely rapid economic growth the scale and seriousness of environmental problems are no longer in doubt whether pollution abatement technologies are utilized more efficiently is crucial in the analysis of environmental management because it influences the cost of alternative production and pollution abatement technologies in this study we use state level industry data of sulfur dioxide nitrogen dioxide and suspended particular matter over the period 1991 2003 employing recently developed productivity measurement technique we show that overall environmental productivities decrease over time in india furthermore we analyze the determinants of environmental productivities and find environmental kuznets curve type relationship existences between environmental productivity and income panel analysis results show that the scale effect dominates over the technique effect therefore a combined effect of income on environmental productivity is negative

income inequality and pollution a reassessment of the environmental kuznets curve abstract improvements in some measures of air and water quality can accompany rising per capita income as illustrated by the so called environmental kuznets curve for pollution variables which show such a relationship we hypothesize that a more equitable distribution of power contributes to these outcomes by enhancing the influence on policy of those who bear the costs of pollution relative to the influence of those who benefit from pollution generating activities an empirical analysis of international variations in seven indicators of air and water quality supports this hypothesis literacy political rights and civil liberties are found to have particularly strong effects on environmental quality in low income countries

contracts hold up and exports textiles and opium in colonial india trade and export it is argued spur economic growth this paper studies the microeco nomics of exporting we build a heuristic model of transactions between exporters and producers and relate it to east india company operations in colonial bengal our model and the historical record stress two difficulties the exporter and its agents might not uphold payment agreements and producers might not honor sales contracts the model shows when procurement succeeds or fails highlighting the tension between these two hold up problems we analyze several cases including the east india company s cotton textile venture the famous opium monopoly and present day contract farming

corruption pollution and the kuznets environment curve abstract this paper examines the implications of corruption and rent seeking behavior by the government for the relationship between pollution and growth cases of both cooperative and non cooperative interaction between the government and the private firm are studied it is shown that corruption is not likely to preclude the existence of an inverted u shaped kuznets environmental curve under both these cases however for any level of per capita income the pollution levels corresponding to corrupt behavior are always above the socially optimal level further the turning point of the kuznets curve takes place at income and pollution levels above those corresponding to the social optimum

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

mortgage modification and strategic behavior evidence from a legal settlement with countrywide abstract we investigate whether homeowners respond strategically to news of mortgage modification programs we exploit plausibly exogenous variation in modification policy induced by settlement of us state government lawsuits against countrywide financial corporation which agreed to offer modifications to seriously delinquent borrowers using a difference in differences framework we find that countrywide s monthly delinquency rate increased more than 0 54 percentage points a 10 percent relative increase immediately after the settlement s announcement the estimated increase in default rates is largest among borrowers least likely to default otherwise these results suggest that strategic behavior should be an important consideration in designing mortgage modification programs jel d14 g21 k22 r31

the missing missing middle the notion that the distribution of firm size in poor countries is characterized by a bimodal distribution with a missing middle is a widely accepted fact in development economics for example see krueger 2013 the idea of the missing middle is that there are a large number of small firms some large firms but very few medium sized firms the purported fact about the missing middle is cited as evidence for two broad stories of why many countries are poor perhaps surprisingly these models look for the cause of the missing middle in two fundamentally different places one approach suggests that small firms are disfavored in low income countries for example by a lack of access to financial capital and thus face difficulties in growing to become middle sized firms the other approach posits a dual economy of large high productivity firms and small low productivity firms and then suggests that larger firms are disfavored in low income countries for example by having to bear large fixed costs of regulation which make it difficult for middle sized firms to become established we begin by reviewing these theories of development based on the purported fact of a missing middle we then explore the evidence on distribution of firm sizes in more detail and challenge the presumption that a missing middle occurs at all we present three main facts first there is in fact no evidence of a missing middle in detailed and comprehensive data on the size of manufacturing firms in india indonesia or mexico regardless of how we slice the data to be sure there

non public competition and public school performance evidence from west virginia abstractin this study we investigate whether non public school enrolment affects the performance of public school districts if homeschooling and private schools act as competition public school districts test scores should be positively associated with non public enrolment using data on west virginia county school districts and controlling for endogeneity with an instrumental variables approach we find that a one standard deviation increase in relative non public enrolment in a county is associated with statistically significant improvements in public school district test scores our findings thus confirm that non public enrolment and the competition it provides act to improve rather than impede public school performance

a panel data heterogeneous bayesian estimation of environmental kuznets curves for co2 emissions this article investigates the environmental kuznets curves ekc for co2 emissions in a panel of 109 countries during the period 1959 to 2001 the length of the series makes the application of a heterogeneous estimator suitable from an econometric point of view the results based on the hierarchical bayes estimator show that different ekc dynamics are associated with the different sub samples of countries considered on average more industrialized countries show evidence of ekc in quadratic specifications which nevertheless are probably evolving into an n shape based on their cubic specification nevertheless it is worth noting that the eu and not the umbrella group led by us has been driving currently observed ekc like shapes the latter is associated to monotonic income co2 dynamics the eu shows a clear ekc shape evidence for less developed countries consistently shows that co2 emissions rise positively with income though there are some signs of an ekc analyses of future performance neverthe

gospel or disaster an empirical study on the environmental influences of domestic investment in china abstract since the beginning of china s reform and opening up in late 1970s the contradiction between environmental quality and economic development has become increasingly acute as the main driving force of development china s fixed asset investment fai has grown rapidly in the meanwhile china s energy consumption surged and the environmental pressures mounted the surge in fai may have great influences on the environmental quality on the one hand the rapid increase in fai facilitated the development of the secondary industry especially energy and pollution intensive industries which brought about significant amount of energy related pollution on the other hand growing investment on environmental investment is expected to slow environmental deterioration moreover the environmental quality and domestic investment may have potential spatial correlations in this paper after fully accounting for the spatial dependence the relationship between domestic investment and environmental quality in china is quantitatively investigated using co2 and so2 as two representative pollutants the estimation results indicate that the spatial dependence indeed exists and total effects of fai on pollutant emissions are positive however there is no evidence that environmental protection investment had expected effects to effectively curb pollutant emissions in china

community pressure and clean technology in the informal sector an econometric analysis of the adoption of propane by traditional mexican brickmakers abstract in many developing countries the informal sector comprised of low technology unlicensed micro enterprises is a major source of pollution environmental management in this sector is exceptionally challenging though clean technologies offer a means of mitigating the problem to our knowledge there has been no rigorous empirical research on why informal or even small scale firms do and do not adopt them as a first step toward filling this gap this paper presents the results of an econometric analysis of the diffusion of propane among informal traditional brickmakers in cd juarez mexico a leading source of air pollution owing to their reliance on cheap highly polluting fuels such as used tires and scrap wood the two key policy implications of our analysis are that 1 it is possible to successfully promote the adoption of a clean technology by intensely competitive informal firms even when the new technology significantly raises variable costs and 2 community pressure applied by competing firms and private sector local organizations can generate incentives for adoption

bureaucratic corruption and endogenous economic growth there appears to be significant diversity in the incidence of bureaucratic corruption across countries at different stages of economic development and under different political and economic regimes little theoretical or empirical analysis has been offered however on the link between corruption government and growth the paper attempts to fill the void through equilibrium models of endogenous growth balanced growth is derived as a balancing act between accumulating human capital which engenders growth and accumulating political capital which mainly assures bureaucratic power the analysis focuses on the interplay between investment in these two types of capital and its implications for long term growth under alternative political regimes some propositions are tested and confirmed empirically
