energy market liberalization and renewable energy policies in oecd countries abstract this paper investigates the effect of energy liberalization compared to other drivers on policies that support renewable energy in a long panel of oecd countries we estimate this effect by accounting for the endogeneity of liberalization related to joint decisions within a country s energy strategy using regulation in other industries as instruments we find that energy liberalization increases public support for renewable energy the effect of liberalization is the second largest after the effect of per capita income and is mostly driven by reductions in entry barriers while the effect of privatization is unclear this finding suggests that a reduction in the monopolistic power of state owned utilities has a positive effect on renewable energy policies when various types of actors are ensured access to the grid instead of it being provided to only a few large private firms

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

existence and fairness of value allocation without convex preferences abstract shafer econometrica 48 1980 467 476 proved that in a finite exchange economy value allocations exist provided that each agent has convex complete transitive compact and monotone preferences however if preferences are not convex then value allocations may not exist to remedy this difficulty we enlarge the set of value allocations by introducing the concept of approximate value allocations and show that in a finite exchange economy approximate value allocations exist even if preferences are not convex or compact or monotone this value existence result can be used to provide a very general value existence theorem for a sequence of finite economies further we show that value allocations may discriminate in favor of or against a coalition of agents

the role of monitoring of corruption in a simple endogenous growth model i introduction during the last 30 years economists from various fields have contributed to the analysis of corruption the first paper to receive widespread attention was published in 1975 rose ackerman 1975 since then a large literature has developed and much attention has been paid to the relationship between corruption and economic growth in the analysis of the consequences of corruption the literature supports two opposing positions on one hand common wisdom views corruption as an obstacle sand to development and growth on the other hand other researchers since the pioneering works of left 1964 and huntington 1968 have suggested that corruption may promote efficiency by allowing firms to bypass government failures of various sorts grease corruption more recent expositions of efficiency enhancing corruption can be found in lui 1985 acemoglu and verdier 1998 2000 and barreto 2000 barreto 2000 presents a simple neoclassical endogenous growth model where the public sector s monopolistic position is explicitly considered results indicate that a corruption equilibrium is characterized by lower growth rates compared to the ideal situation in which public goods are provided competitively barreto 2000 also shows that if the public sector is subject to significant bureaucratic red tape all of the agents within the economy may prefer the corruption equilibrium as corruption can bypass bureaucratic obstacles from a theoretical point of view there are several ways in which corruption may reduce economic growth corruption can act as a tax and thus lower incentives to invest corruption could cause talented people to engage in rent seeking rather than productive activities corruption may distort the composition of government expenditure as corrupt politicians could be expected to invest in large non productive projects from which considerable bribes can be extracted more easily than from productive activities empirical analysis has also provided evidence of the negative effects of corruption on economic growth mauro 1995 shows that corruption reduces economic growth via reduced private investment 1 similar results are obtained by keefer and knack 1995 using other measures of corruption and a different selection of countries 2 recently the grease the wheels hypothesis has been tested and statistically supported see aidt 2009 campos dimova and ahmad 2010 meon and sekkat 2005 among others in this article we develop a theoretical endogenous growth model which incorporates corruption in our model the social loss brought about by corruption stems from the fact that firms must bribe a bureaucrat in order to invest and consequently devote fewer resources to the accumulation of capital therefore in our model corruption has a negative effect on private investment other models share our framework ehrlich and lui 1999 claim that individuals have an incentive to compete over the privilege of becoming bureaucrats the so called investment in political capital since they obtain economic rents through corruption this investment in political capital consumes economic resources which could otherwise be used for production or investment in human capital in del monte and papagni 2001 corruption arises when bureaucrats manage public resources to produce public goods and services corruption reduces the quality of public infrastructure resulting in a negative effect on economic growth the novel feature of this article is the study of the impact of monitoring of corruption on economic growth 3 in our theoretical model we derive a nonlinear relationship between the level of monitoring and economic growth as well as between corruption and economic growth 4 at low monitoring levels the economy experiences widespread corruption and medium growth rates whereas no corruption occurs at intermediate monitoring levels but low growth rates are recorded

common agency and coordination general theory and application to government policy making we develop a model of common agency with complete information and general preferences with nontransferable utility and we prove that the principals nash equilibrium in truthful strategies implements an efficient action we apply this theory to the construction of a positive model of public finance where organized special interests can lobby the government for consumer and producer taxes or subsidies and targeted lump sum taxes or transfers the lobbies use only the nondistorting transfers in their noncooperative equilibrium but their intergroup competition for transfers turns into a prisoners dilemma in which the government captures all the gain that is potentially available to the parties

does democracy lead to a better environment deforestation and the democratic transition peak the relationship between democracy and environment is subject to controversy some scientists find that democracy has a positive impact in reducing environmental disruption other scholars claim that democracy tends to accelerate environmental degradation by using deforestation rates as a proxy for environmental disruption we suggest that both sides might be right our quantitative analysis has three important outcomes first there is evidence of an inverted u shaped relationship between deforestation and democracy second countries in democratic transition experience the highest deforestation rates compared to non democracies and mature democracies third in explaining deforestation rates democracy has larger explanatory power than income this last result implies that in reducing deforestation rates the emphasis should not only be on economic development but even more on democratization

legislative organization and pollution taxation the role of political institutions in shaping public policy has been analyzed in isolation from corruption and legislative organization specifically bicameralism has received minimal attention we analyze pollution taxation when decisions are influenced by several veto players such as legislative chambers our theory predicts that an increase in the number of veto players e g moving from uni to bi cameralism pushes the pollution tax towards the social optimum with the effect being conditional on corruption as such dispersion around the optimal tax is lower under bicameralism empirical tests using data from 86 countries support the theory

non symmetric cardinal value allocations it is shown that cardinal value allocations may fail to be symmetric specifically agents with identical preferences and identical endowments can be treated very differently at a cardinal value allocation this casts further doubt on the interpretation of the weights as endogenous utility comparisons

corruption and infrastructure at the country and regional level abstractthis paper examines the relationship between corruption and infrastructure at both the country and regional level using the world bank s enterprise surveys data a statistically significant and considerable relationship is established between the measure of corruption in the macro data and the measures of transportation and electricity infrastructure countries with more corruption tend to have worse infrastructure at the regional level the key result is unchanged the magnitude and significance of this result is shown to vary by global region two stage least squares results using distance from the equator as an instrument at the macro level support the simple ordinary least squares ols finally it is shown that within country variation in corruption has a significant effect on regional infrastructure

political internalization of economic externalities and environmental policy abstract this paper derives the characteristics of endogenous environmental policy in a common agency model of politics and proceeds to show that competition between lobby groups is an important source of internalization of economic externalities our analysis generalizes bhagwati s principle of targeting to the case of distorted political markets moreover we show that the politically optimal structure of environmental taxes incorporates a pigouvian adjustment however since lobby groups care about the distribution of income as well as about efficiency the equilibrium structure of taxes differs considerably from the pigouvian rule

income distribution political instability and investment abstract this paper successfully tests on a sample of 71 countries for the period 1960 85 the following hypotheses income inequality by fuelling social discontent increases sociopolitical instability the latter by creating uncertainty in the politico economic environment reduces investment as a consequence income inequality and investment are inversely related since investment is a primary engine of growth this paper identifies a channel for an inverse relationship between income inequality and growth we measure socio political instability with indices which capture the occurrence of more or less violent phenomena of political unrest and we test our hypotheses by estimating a two equation model in which the endogenous variables are investment and an index of socio political instability our results are robust to sensitivity analysis on the specification of the model and the measure of political instability and are unchanged when the model is estimated using robust regression techniques

environmental depletion governance and conflict t he link between natural resource dependence and internal conflict has been approached from a variety of angles in a large and growing interdisciplinary literature while there is an expanding consensus as to what matters the most for such intra state violence episodes the feasibility discontent dichotomy still appears to characterize a disciplinary divide between economists and political scientists this paper attempts to help bridge the gap by allowing for both intrinsic and extrinsic motivations of potential rebels simple non cooperative bargaining yields a nonlinear impact of regulatory quality on the likelihood of conflict and shows that corruption and resource depletion jointly affect the outcome the empirical analysis that follows looks at the effect of environmental depletion and government corruption on the emergence of civil conflicts using a large panel dataset resource depletion the quality of governance and their interaction are found to be significant determinants of civil conflict incidence results are robust to several steps taken to address potential endogeneity concerns

distance constraints the limits of foreign lending in poor economies how far does mobility of multinational banks solve problems of financial development using a panel of 80 000 loans over 7 years i show that greater cultural and geographical distance between a foreign bank s headquarters and local branches leads it to further avoid lending to informationally difficult yet fundamentally sound firms requiring relational contracting greater distance also makes them less likely to bilaterally renegotiate and less successful at recovering defaults differences in bank size legal institutions risk preferences or unobserved borrower heterogeneity cannot explain these results these distance constraints can be large enough to permanently exclude certain sectors of the economy from financing by foreign banks

the voluntary provision of a pure public good the case of reduced cfc emissions and the montreal protocol abstract this paper applies the theory of the voluntary provision of a pure public good to the behavior of nations to curb chlorofluorocarbon cfc emissions during the late 1980s by devising an empirical test we determine that these cutbacks in emissions are consistent with nash behavior when taste parameters are controlled the relationship between emission cutbacks and national income is nearly linear as implied by the theory if the sample is purged of potential outliers then the linear relationship results a significant taste parameter is the extent of political and civil freedoms while a marginally significant parameter is geophysical position in terms of latitude

is income inequality a driver for renewable energy consumption abstract although many initiatives have been made to research the effect of income inequality on environmental issues the question of whether income inequality affects renewable energy consumption hasn t been answered this gap in the literature raises an important question that needs to be answered by researchers can the income inequality affect renewable energy consumption as far as is known the study is the first attempt to discover this relationship therefore the impact of income inequality on renewable energy consumption is examined theoretically and empirically in 43 developed and developing countries for 2000 2015 in order to avoid the omitted variable problem economic environmental and institutional variables such as gdp per capita corruption co2 emissions and trade openness are included in the model the results demonstrate that the decline in income inequality will enhance renewable energy consumption in other words policymakers have the opportunity to reduce income inequality and environmental degradation at the same time similarly corruption control and raise co2 emissions will increase also renewable energy consumption otherwise economic determinants such as economic growth and trade openness have no meaningful effect on renewable energy consumption

approximate equilibria with bounds independent of preferences authors prove the existence of approximate equilibria in exchange economies giving bounds on the excess demand in terms of the number of traders and norms of the endowments but independent of the preferences

corruption is bad for growth even in the united states we estimate the impact of corruption on growth of output per worker in u s states we improve on existing studies of the cost of corruption by using a better specified empirical model focusing on a study population that is less likely to be affected by parameter heterogeneity and controlling for endogeneity using political variables to instrument for corruption we find that corruption plays a significant and causal role in lowering growth and investment across the states

green havens and pollution havens we test for pollution haven effects in outward foreign direct investment fdi for different sectors using a comprehensive and exhaustive data set for outward fdi from the netherlands one of the most environmentally stringent countries and a major source of global fdi our evidence suggests that in the sectors natural resources extraction and refining construction retail food processing beverages and tobacco and utilities a less stringent environmental policy in the host country significantly attract fdi what is important for these pollution haven effects is not only regulation but also enforcement of environmental policy in contrast to earlier results it is not only footloose industries that display pollution haven effects but also the traditional pollution intensive industries but for the machines electronics and automotive and transportation and communication sectors a more stringent and better enforced environmental policy attracts more fdi as this may help their reputation for sustainable management and csr these sectors display green haven effects these findings have important implications for the sector distribution of fdi in destination countries

environmental performance in socially fragmented countries social fragmentation is often associated with reduced co operative behaviour which undermines public goods provision such as environmental protection the few studies linking social fragmentation and environmental performance have been confined to using ethnic fractionalisation as the only measure of social heterogeneity in this paper we contribute to the literature in a twofold manner first we bring into the analysis alternative measures of social fragmentation i e religious fractionalisation ethnic religious polarisation that have received considerable attention in development economics in recent years second this is the first study to our knowledge that makes use of a large panel dataset of several environmental indicators to explore links between ethnic religious diversity and the environment we find that all indices of social fragmentation are negatively linked to measures of environmental quality although for some of them the size of the effect is larger in the case of polarisation

an empirical investigation of the pollution haven effect with strategic environment and trade policy abstract using a new dataset on the stringency and enforcement of environmental policy this study is the first to find robust confirmation of a pollution haven effect in a cross country context by accounting for strategically determined environment trade and intellectual property right ipr policies a simple game theoretic approach to policy determination is described which suggests an identification strategy based on other country characteristics it is found that for the top 20th percentile of countries in terms of growth in u s multinational affiliate value added as much as 8 6 of that growth between 1999 and 2003 can be attributed to declining relative stringency and enforcement of environmental policy the results are robust to a number of identification tests weak iv tests and third country spatial effects further evidence is found that relatively footloose industries are more likely to be affected by environmental policy than more traditionally dirty industries and enforcement of environmental policies tends to be a more important deterrent than the stringency of the policy set

split sample instrumental variables estimates of the return to schooling this article reevaluates recent instrumental variables iv estimates of the returns to schooling in light of the fact that two stage least squares is biased in the same direction as ordinary least squares ols even in very large samples we propose a split sample instrumental variables ssiv estimator that is not biased toward ols ssiv uses one half of a sample to estimate parameters of the first stage equation estimated first stage parameters are then used to construct fitted values and second stage parameter estimates in the other half sample ssiv is biased toward 0 but this bias can be corrected the splt sample estimators confirm and reinforce some previous findings on the returns to schooling but fail to confirm others

uncovering the complex relationships between political risk and mne firm legitimacy insights from libya using the before after natural experiment occasioned by the arab spring in libya we explore how market and non market activity affect foreign firm legitimacy in times of political turmoil although all mnes in libya had to cultivate strong ties to qadhafi to succeed during his 40 years of rule we found that those that also invested in social benefit projects and in social ties with families with few ties to the qadhafi family earned a broad based legitimacy that helped them survive qadhafi s overthrow our findings contribute to the political risk and political behavior literature the notion that the pursuit of firm legitimacy in general and especially in the eyes of social sector actors is an effective hedge against political risk more theoretically our findings support the addition of a social sector based path to firm legitimacy in the host country that complements and may at times substitute for the government based path to foreign firm legitimacy practically our findings suggest that mnes facing severe political risk can improve their prospects for survival by investing in relationships with influential social groups and by offering goods or services that are perceived as socially valuable

approximate equilibria in markets with indivisible commodities abstract this paper presents results on the existence of approximate equilibria in large but finite exchange economies in which all the traders have non convex consumption sets as such the paper gives a natural extension to the finite economy of mas colell s results on existence with indivisible commodities and a continuum of agents it also presents an approximate equilibrium theorem without any assumption of compactness or bounded non convexity of preferences

emerging stock markets portfolio capital flows and long term economie growth micro and macroeconomic perspectives abstract the paper examines two major components of financial liberalization stock market development and portfolio capital flows in the context of less developed countries the paper considers microeconomic and macroeconomic perspectives on their implications for long term development and economic growth it concentrates on 1 a the role of stock markets in financing corporate growth 2 b the implications of stock market volatility for resource allocation and productive efficiency and 3 c the interactions between the foreign exchange and stock markets in the context of economic shocks its policy recommendations are that ldcs should promote bank based systems influence the scale and composition of capital inflows and prevent a market for corporate control from emerging

lobbying and welfare in a representative democracy this paper studies the impact of lobbying on political competition and policy outcomes in a framework which integrates the citizen candidate model of representative democracy with the menu auction model of lobbying positive and normative issues are analysed on the positive side lobbying need have little or no effect on policy outcomes because voters can restrict the influence of lobbyists by supporting candidates with offsetting policy preferences on the normative side coordination failure among lobbyists can result in pareto inefficient policy choices in addition by creating rents to holding office lobbying can lead to excessive entry into electoral competition

finance is good for the poor but it depends where you live i examine whether or not the incomes of the poor systematically grow with average incomes and whether financial development enhances the incomes of the poorest quintile following the methodology of dollar and kraay 2002 i find once extending dollar and kraay s data their findings are robust to the lucas critique and economic growth is important for poverty reduction universally however in comparison to other authors work i show financial development aids the incomes of the poor in certain regions whilst it may be detrimental in others this proposes evidence against a one size fits all model adding a further contribution to the literature on financial development and poverty

seigniorage and political instability the importance of seigniorage relative to other sources of government revenue differs markedly across countries this paper tries to explain this regularity by studying a political model of tax reform the model implies that countries with a more unstable and polarized political system will have more inefficient tax structures and thus will rely more heavily on seigniorage this prediction of the model is tested on cross sectional data for seventy countries the authors find that after controlling for other variables political instability is positively associated with seigniorage copyright 1992 by american economic association

does foreign aid distort incentives and hurt growth theory and evidence from 75 aid recipient countries foreign aid transfers can distort individual incentives and hence hurt growth by encouraging rent seeking as opposed to productive activities we construct a model of a growing small open economy that distinguishes two effects from foreign transfers i a direct positive effect as higher transfers allow the financing of infrastructure ii an indirect negative effect as higher transfers induce rent seeking competition by self interested individuals in this framework the growth impact of aid is examined jointly with the determination of rent seeking behavior we test the main predictions of the model for a cross section of 75 aid recipient countries there is evidence that aid has a direct positive effect on growth which is however significantly mitigated by the adverse indirect effects of associated rent seeking activities this is especially the case in recipient countries with relatively large public sectors

firm size government capacity and regional environmental regulation theoretical analysis and empirical evidence from china abstract the size and number of firms in a region represent key characteristics of that regional economic ecosystem but few studies have linked such characteristics with the stringency of local environmental regulation in this study we discuss the effects of local firm scale on environmental regulation and its mechanism and the optimal strategic choices theoretically and empirically for environmental regulation in regions with different firm scale we find that when government capacity is insufficient regional environmental regulation will be relatively more stringent when dealing with fewer but larger firms because of the government scale effect when government capacity is sufficient firm size has no influence on environmental regulation our results are robust and offer insights for government decision makers to improve local environmental regulation efficiency

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

political institutions and pollution control this paper models the selection of environmental policies under authoritarian and democratic regimes and tests the hypothesis that political institutions systematically affect the enactment of environmental regulations the results support the contention that political institutional arrangements rather than resource endowments largely determine policies concerning environmental regulation copyright 1992 by mit press

estimates of returns to scale elasticity of substitution and the thrifty food plan meal poverty rate from a direct household meal production function abstract many nutritional policies are designed to make home food production more affordable and yet very little is actually known about the home food production process a better understanding of home food production can be used to help explain shortcomings in current nutrition policies and consequently help in designing better nutrition policies this paper provides results from several home meal production function specifications that are rather robust the median returns to scale and elasticity of substitution between money and time is in the 1 2 1 9 range and 33 56 range respectively indicating increasing returns to scale but difficulty in substituting money for time in home meal production a home meal poverty rate is estimated which is the percentage of the sample that produces fewer meals at home than consistent with dietary guidelines the estimated home meal poverty rate is about 85 which is consistent with recent research taking a less rigorous approach though the approach taken here is novel the overall message is consistent with the recent literature time is a more important factor in achieving nutritional targets than money

on the validity of econometric techniques with weak instruments inference on returns to education using compulsory school attendance laws we evaluate angrist and krueger 1991 and bound jaeger and baker 1995 by constructing reliable confidence regions around the 2sls and liml estimators for returns to schooling regardless of the quality of the instruments the results indicate that the returns to schooling were between 8 and 25 percent in 1970 and between 4 and 14 percent in 1980 although the estimates are less accurate than previously thought most specifications by angrist and krueger 1991 are informative for returns to schooling in particular concern about the reliability of the model with 178 instruments is unfounded despite the low first stage f statistic finally we briefly discuss bias adjustment of estimators and pretesting procedures as solutions to the weak instrument problem

does compulsory school attendance affect schooling and earnings we establish that season of birth is related to educational attainment because of school start age policy and compulsory school attendance laws individuals born in the beginning of the year start school at an older age and can therefore drop out after completing less schooling than individuals born near the end of the year roughly 25 percent of potential dropouts remain in school because of compulsory schooling laws we estimate the impact of compulsory schooling on earnings by using quarter of birth as an instrument for education the instrumental variables estimate of the return to education is close to the ordinary least squares estimate suggesting that there is little bias in conventional estimates every developed country in the world has a compulsory schooling requirement yet little is known about the effect these laws have on educational attainment and earnings 1 this paper exploits an unusual natural experiment to estimate the impact of compulsory schooling laws in the united states the experiment stems from the fact that children born in different months of the year start school at different ages while compulsory schooling laws generally require students to remain in school until their sixteenth or seventeenth birthday in effect the interaction of school entry requirements and compulsory schooling laws compel students born

why a stubborn conservative would run a deficit policy with time inconsistent preferences a conservative government in favor of a low level of public consumption knows that it will be replaced by a government in favor of a larger level of public consumption we show that the resulting level of public consumption is in between the levels the two governments would choose if each were in power both in the present and in the future in particular we show that if the conservative government is more stubborn in a particular sense than the succeeding government the conservative government will borrow more than it would had it remained in power in the future

moral hazard and marshallian inefficiency evidence from tunisia abstract we formalize the link between optimal cost sharing contracts and the production technology in the presence of moral hazard by appealing to several well known results from duality theory building on intuitions from the interlinkage literature we show that optimal contractual structure is determined by the i substitution possibilities that exist between different observable factor inputs as well as ii between these inputs and unobservable effort we endogenize contractual choice using landlord characteristics as instruments exploiting the fact that in our dataset landlords interact with several tenants and vice versa the approach is applied to an unbalanced plot level panel of cost sharing contracts in a tunisian village using a translog representation of the restricted profit function contractual terms are found to be a significant determinant of input use and therefore lead to marshallian inefficiency while the optimality of the underlying contractual structure is rejected

finance and inequality the case of india although theory emphasizes the role of financial market frictions in explaining income inequality there is little empirical research exploring how financial development and financial sector reforms influence the evolution of income inequality this article examines how finance impacts income inequality in india using annual time series data for over half a century the results indicate that while financial development helps reduce income inequality financial liberalization seems to exacerbate it the results are robust to the use of different measures for financial development and financial liberalization although the relationship between financial development and economic growth has been extensively studied in the literature see for example king and levine 1993 demetriades and hussein 1996 arestis and demetriades 1997 levine loayza and beck 2000 bell and rousseau 2001 ang and mckibbin 2007 little is known about how finance impacts income inequality the importance of the finance inequality relationship has recently been highlighted in an insightful survey article by claessens and perotti 2007 they indicate that while financial development can help reduce income inequality financial liberalization captured by established interests may do the opposite the theoretical predictions of the effects of finance on income inequality are controversial rajan and zingales 2003b argue that improvements in the formal financial sector primarily benefit the rich greenwood and jovanovic 1990 predict a nonlinear relationship between financial development and income inequality where it is hypothesized that income inequality first increases with the degree of sophistication in the financial systems then stabilizes and eventually declines others propose that the presence of financial market imperfections deters the poor from borrowing adequately to invest in human and physical capital implying that financial development helps alleviate income inequality banerjee and newman 1993 galor and zeira 1993 aghion and bolton 1997 mookherjee and ray 2003 2006 given that theories provide ambiguous predictions regarding the effects of finance on the distribution of income it is useful to approach the issue at the empirical level this could facilitate our understanding of the relationship between finance and inequality and help us to assess the validity of each theoretical model despite the important role of financial market frictions in the theories of poverty and income inequality researchers so far have not adequately addressed whether financial

statehood experience legal traditions and climate change policies this study investigates how the implementation of modern climate change policies is related to former colonies length of state history and their legal heritage we argue that countries with longer statehood experience around the time of colonization were better equipped to implement the legal philosophies transplanted by their colonial powers therefore the implications of receiving british common law versus french civil law should be particularly important in countries with a greater accumulated history of statehood using a cross section of up to 78 former colonies our results provide support for this hypothesis in particular our estimates demonstrate that common law countries have weaker modern climate change policies than civil law countries and the difference is inflated by a longer statehood experience measured by the length of state history from 1 to 1800 ad legal origin has no effect in areas which by the time of colonization had no statehood experience finally we report similar results for the pattern of labor market regulations jel k15 k31 k32 o44 q54 q58

within groups wage inequality and schooling further evidence for portugal this article provides further evidence on the positive impact of schooling on within groups wage dispersion in portugal using data on male workers from the 2001 wave of the european community household panel the issue of schooling endogeneity is taken into account by using the latest available instrumental variable technique for quantile regression i e the control function estimator due to lee 2007 the findings are compared with earlier results based on different techniques i e the instrumental variable estimator due to arias et al 2001 and the standard exogeneity based estimator due to koenker and bassett 1978

identification weak instruments and statistical inference in econometrics we discuss statistical inference problems associated with identification and testability in econometrics we consider inference in non parametric models and weakly identified structural models weak instruments we point out that many ill defined statistical problems such as non testable hypotheses occur in these areas and are typically associated with asymptotic approximations in non parametric models such problems include testing moments and inference under heteroscedasticity or serial dependence of unknown form for weakly identified structural models difficulties are typically associated with improper pivots and we review recent developments aimed at proposing more reliable procedures including alternative proposed statistics bounds projection split sampling conditioning monte carlo tests jel classification c1 c12 c14 c15 c3 c5 identification instruments faibles et inference statistique en econometrie nous analysons les problemes d inference associes a l identification et a la testabilite en econometrie nous considerons l inference dans les modeles non parametriques et les modeles structurels faiblement identifies instruments faibles nous remarquons que beaucoup de problemes mal poses tels que des hypotheses non testables apparaissent dans ces domaines et que ceux ci sont typiquement associes a l emploi d approximations asymptotiques dans les modeles non parametriques de tels problemes incluent les tests sur les moments et l inference sous heteroscedasticite ou dependance serielle de forme non specifiee dans les modeles structurels faiblement identifies ces difficultes sont habituellement associees a l emploi de fonctions pivotales impropres et nous presentons un survol des methodes recentes ayant pour objectif d obtenir des procedures plus fiables ce qui comprend les differentes statistiques proposees l emploi de bornes la subdivision d echantillon les techniques de projection le conditionnement et les tests de monte carlo

ownership risk investment and the use of natural resources the effect of insecure ownership on ordinary investment and natural resource use is examined insecure ownership is postulated to depend on the type of government regime in power and the prevalence of political violence or instability the political determinants of economy wide investment are estimated from cross country data and the results are used to form an index of ownership security when introduced into empirical models of natural resource use this index has a significant and quantitatively important effect on the use of forests and petroleum contrary to conventional wisdom ownership risk slows resource use in some circumstances

environmental regulations transfers and trade theory and evidence abstract this paper develops a theory of compensation of producers for the costs associated with environmental regulations we show that the existence of transfers can give counter intuitive effects of environmental policy on both output and trade flows in particular the compensation obtained by producers neutralizes the effect of environmental policy on output and consequently on trade flows this may help explain why previous empirical research has found weak evidence that environmental regulations affect trade patterns the theory is tested using agricultural sector data the evidence supports the hypothesis that environmental regulations and transfers are positively correlated

weight discrimination in the german labour market abstractwe explore the effects of higher body mass index bmi or obesity on different labour market outcomes we extend the present literature by investigating the effect of obesity on i promotion likelihood and ii unemployment duration in addition to the effect on iii wages and iv probability of being employed we find an obesity penalty on wages employment likelihood promotion likelihood and unemployment duration among females in germany taking into account of endogeneity of bmi and sample selection we are also able to identify an unexplained effect of obesity on wages employment and promotion likelihood for females using decomposition techniques that can be attributed to weight discrimination

the effects of rural electrification on employment new evidence from south africa this paper estimates the impact of electrification on employment growth by analyzing south africa s mass roll out of electricity to rural households using several new data sources and two different identification strategies an instrumental variables strategy and a fixed effects approach i find that electrification significantly raises female employment within five years this new infrastructure appears to increase hours of work for men and women while reducing female wages and increasing male earnings several pieces of evidence suggest that household electrification raises employment by releasing women from home production and enabling microenterprises migration behavior may also be affected jel h54 l94

corruption and growth under weak identification i introduction the purpose of this paper is to revisit mauro 1995 and re examine his results as a consequence of recent research that cautions against making traditional types of inference in the presence of weak instruments early work done by nelson and startz 1990a 1990b demonstrates that the distribution of the two stage least squares 2sls estimator and the t statistic is poorly approximated by the asymptotic representation when instruments are weak more formally staiger and stock 1997 model the coefficients on the instruments in the first stage equation in the n sup 1 2 neighborhood of zero in which they show that the 2sls estimator loses consistency resulting in a nonstandard distribution for the t statistic in fact they show that under the local to zero framework the distribution of the t statistic depends on the level of endogeneity strength and the number of instruments thus the true size of the t statistic can differ substantially from its perceived size when instruments are weak therefore 95 confidence intervals based on asymptotic approximations such as or 1 96se are no longer reliable as a rough rule of thumb staiger and stock 1997 suggest a first stage f stat of 10 on the excluded instruments as an indication of acceptable instruments in terms of point estimation bound jaeger and baker 1995 show that the 2sls estimator is biased in the same direction as the ordinary least squares ols when using irrelevant instruments hahn and hausman 2002 illustrate a detailed expression for the 2sls bias showing that it is monotonically decreasing in the instrument strength while monotonically increasing in the degree of endogeneity cruz and moreira 2005 verify these results through monte carlo simulations also showing that the classic bias corrected 2sls estimator of nagar 1959 provides a poor correction when instruments are very weak given that the theory and techniques mentioned above were discovered and developed after mauro wrote his qje paper we attempt to reproduce his results and analyze them in light of these recent findings from the early work of left 1964 and huntington 1968 corruption in government has been of great interest to economists these studies argue that corruption could be positively correlated with economic performance in the presence of a thick and cumbersome bureaucracy corruption in this view greases the wheels of bureaucracy thus increasing the efficiency in which transactions occur leading to a positive effect on the economic performance of a country on the other hand rose ackerman 1978 murphy shleifer and vishny 1991 1993 and shleifer and vishny 1993 provide theoretical arguments that corruption deteriorates economic growth through the misallocation of talent and other resources mauro 1995 being the first to introduce instrumental variables ivs in the cross country growth literature contributes to this debate by examining empirically the relationship between two measures of corruption and investment and economic growth his results suggest that corruption has a negative impact on investment and economic growth the significance of his results varies with model specifications but the results appear to be robust when correcting for the endogeneity of corruption using the ethnolinguistic fractionalization elf index as an iv he employs 2sls estimation to correct for endogeneity created by the two measures of corruption mauro 1995 s work has been of great value in the corruption literature and has had profound influence on the direction of policy making the paper is one of the most cited papers not just in the literature on corruption but in economics in general 1 given the impact that the paper has undoubtedly had on the direction of research we find it necessary and relevant to revisit the paper in light of the recent developments in the field of econometrics

a quantitative reassessment of the finance growth nexus evidence from a multivariate var abstract the long run relationship between financial development and economic growth is examined in a multivariate vector autoregression var framework using 10 sample countries difficulties surrounding the cross country regressions and bivariate time series studies are outlined the long run financial development and output relationships are identified in a cointegrating framework through tests of over identifying restrictions we find bi directional causality between financial development and economic growth in all the sample countries conclusions that stand distinct from those in the existing empirical literature we attribute our findings to i analysis of a higher dimensional system ii a new method of identifying the long run economic relationships and iii a new approach to long run causality testing

control of corruption international investment and economic growth evidence from panel data abstract in this paper we study the effects of corruption using an open economy version of the endogenous growth model with international capital mobility in particular the model predicts that corruption negatively affects the stock of international investment in the host country in addition the model predicts that growth should be impaired by the uncertainty caused by corruption bribes unlike taxes involve unpredictable distortion in the discretionary and uncertain use of the government power this results in additional costs to businesses and alongside with resources allocated to unproductive activities impose an extra burden on the economy we test empirically the predictions of the theory using a sample of 142 countries for the period 1994 2014 and gmm methods using indicators of control of corruption from the world bank the lack of corruption is found to have a positive and statistically significant effect on the growth rate of real per capital gdp and increased the investment ratio hence the empirical results suggest that corruption directly hinders economic growth by hampering investment the estimated effects are robust to changes in specifications and estimation methods thus it can be concluded that richer countries with better access to international financing should be growing faster and be less prone to the adverse effects of corruption than the emerging economies

governance and renewable energy investment in mena countries how does trade matter abstract the middle east and north africa mena countries have recently developed renewable energy re markets however their rate of investment in renewable energy remains small compared to other regions in the world despite their relatively abundant endowments particularly in wind and solar while the literature identifies some barriers to investment in renewable energy we assume that the investment of mena countries could be impeded by specific governance factors furthermore we consider recent literature showing that trade openness reduces the negative effects of weak governance in this paper we empirically investigate the link between governance openness and renewable energy investment in the mena region using panel data for 15 mena countries over the period 1996 2013 our results prove that high institutional quality is associated with re investment in mena countries in addition this relationship seems to be conditional on the trade regime our results are robust to several measures of renewable energy investment and governance as well as to an alternative econometric set up

classical competitive analysis of economies with islands arrow debreu competitive equilibrium analysis is extended to environments with information sets differing in space as well as in time and with people moving between locations equilibrium is shown to exist and to be optimal and the equilibrium price system is characterized such environments include many of those studies in the sectoral reallocation literature

the value allocation of an economy with differential information we analyze the shapley value allocation of an economy with differential information since the intent of the shapley value is to measure the sum of the expected marginal contributions made by an agent to any coalition that he she belongs to the value allocation of an economy with differential information provides an interesting way to measure the information advantage of an agent this feature of the shapley value allocation is not necessarily shared by the rational expectation equilibrium thus we analyze the informational structure of an economy with differential information from a different and new viewpoint

the political economy of pollution taxes in a small open economy abstract this paper develops a positive theory explaining pollution tax policy outcomes in a small open economy the equilibrium tax rate depends on lobby group membership the relative importance of lobbying activities and the tax elasticity of pollution the equilibrium properties are investigated the model is extended to incorporate pollution abatement and a pollution abatement subsidy we show that total pollution may be increasing in the pollution abatement subsidy rate this effect arises because the equilibrium pollution tax rate may be decreasing in the subsidy rate due to altered political influence of the lobby groups in the political equilibrium

to ban or not to ban foreign lobbying and cross national externalities this paper studies the costs and benefits of foreign lobbying we show how and when foreign lobbying can help internalize cross national externalities we argue that this is an often overlooked benefit of foreign lobbying we also study under what conditions a constitutional rule banning foreign lobbying is in the national interest of a country a key factor in this calculus is whether the interests of foreign lobby groups and domestic unorganized groups coincide or not we illustrate the logic with examples from trade policy and environmental regulation bannir ou ne pas bannir lobbying etranger et effets externes transnationaux ce texte etudie les couts et avantages du lobbying etranger on montre quand et comment que le lobbying etranger peut aider a internaliser des effets externes transnationaux on suggere que c est souvent un avantage qu on est porte a negliger du lobbying etranger on etudie sous quelles conditions une regle constitutionnelle bannissant le lobbying etranger peut etre dans l interet national d un pays un facteur cle dans ce calcul est le fait que les interets des groupes etrangers coincident ou non avec ceux des groupes nationaux non organises on illustre la logique sous jacente a l aide d exemples portant sur la politique commerciale et la reglementation environnementale

youth dependency and total factor productivity abstract recent literature shows empirical support for an effect of demographic age structure on economic growth this literature does not give attention to the possibility that age structure might also have an effect on total factor productivity much of the recent literature on economic growth has stressed that an understanding of cross country differences in output per worker is needed that literature argues that the most important determinant of international differences in output per worker is differences in total factor productivity this paper finds empirical evidence in cross country data for the thesis that the youth dependency ratio the population below working age divided by the population of working age reduces residual growth which measures total factor productivity growth for this reason the paper demonstrates that age structure has an effect on the most important determinant of international differences in output per worker

an empirical study of the impact of corruption on environmental performance evidence from panel data this paper extends the empirical debate on the effects of corruption on environmental degradation by considering a recently available measure of environmental quality the environmental performance index this indicator is more comprehensive than the measures of air pollutant emissions commonly used in the literature and in particular can also capture the impact of pollution on human health this allows for a better understanding of the actual effects of a wide range of human activities on the ecosystem from a panel data analysis two regularities emerge first corruption deteriorates the overall environmental quality this effect is robust and persistent second our findings highlight the improvement of environmental quality as income rises even at an initial level of development this is not in contradiction with the ekc hypothesis because an increase in income levels provides positive externalities on the whole environmental quality by compensating the mere negative effects induced by industrialization on the emission levels as a consequence in emerging economies policies fighting corruption and enhancing development are very likely to improve the environmental performances

voting on the budget deficit this paper analyzes a model in which a group of rational individuals votes over the composition and time profile of public spending all voters agree that a balanced budget is ex ante optimal however if there is disagreement between current and future majorities a balanced budget is not a political equilibrium under majority rule under certain conditions a majority of the voters favors a budget deficit and the equilibrium deficit is larger the greater is the polarization among voters copyright 1990 by american economic association

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

do rural banks matter evidence from the indian social banking experiment lack of access to finance is often cited as a key reason why poor people remain poor this paper uses data on the indian rural branch expansion program to provide empirial evidence on this issue between 1977 and 1990 the indian central bank mandated that a commercial bank can open a branch in a location with one or more bank branches only if it opens four in locations with no bank branches we show that between 1977 and 1990 this rule caused banks to open relatively more rural branches in indian states with lower initial financial development the reverse is true outside this period we exploit this fact to identify the impact of opening a rural bank on poverty and output our estimates suggest that the indian rural branch expansion program significantly lowered rural poverty and increased non agricultural output

inefficient equilibria in lobbying lobbying is often represented as a common agency game common agency games typically have multiple equilibria one class of equilibria called truthful has been identified by bernheim and whinston quarterly journal of economics 1986 101 1 1 31 in this paper we identify another class of equilibria which we call natural in which each principal offers a positive contribution on at most one alternative we run an experiment on a common agency game for which the two equilibria predict a different equilibrium alternative the alternative predicted by the natural equilibrium is chosen in 65 of the matches while the one predicted by the truthful equilibrium is chosen in less than 5 of the matches 2001 elsevier science b v all rights reserved

aspects of governance and hbox co _2 co 2 emissions a non linear panel data analysis the reduction of hbox co 2 emissions has been at the centre of worldwide debates on environmental issues though its inclusion as one of the millennium development goals mdgs by the united nations has changed the focus of relative literature among many one of the world bank s recipes to achieve a higher position toward mdgs has been to undertake reforms for a better governance while the majority of researches focus has been on one single aspect and its relationship with the environment some studies have simultaneously considered two governance dimensions in this paper we focus on the role of several aspects of governance on hbox co 2 emissions this provides us with a chance to explore the possible impacts of all aspects of governance on a more direct measure of emissions that is different to previous researches which have focused on the indirect transmission and considered the maximum of two using the iv method within panel data analysis we show that only one single aspect of governance control of corruption has a negative significant effect on hbox co 2 emissions and its effect has a non linear relationship the non linearity exists in both parametric and nonparametric analysis after controlling for endogeneity

estimating average and local average treatment effects of education when compulsory schooling laws really matter the change to the minimum school leaving age in the united kingdom from 14 to 15 had a powerful and immediate effect that redirected almost half the population of 14 year olds in the mid twentieth century to stay in school for one more year the magnitude of this impact provides a rare opportunity to a estimate local average treatment effects late of high school that come close to population average treatment effects ate and b estimate returns to education using a regression discontinuity design instead of previous estimates that rely on difference in differences methodology or relatively weak instruments comparing late estimates for the united states and canada where very few students were affected by compulsory school laws to the united kingdom estimates provides a test as to whether instrumental variables iv returns to schooling often exceed ordinary least squares ols because gains are high only for small and peculiar groups among the more general population i find instead that the benefits from compulsory schooling are very large whether these laws have an impact on a majority or minority of those exposed

financial development and economic growth views and agenda this critique argues that the preponderance of theoretical reasoning and empirical evidence suggests a positive first order relationship between financial development and economic growth the body of work would push even most skeptics toward the belief that the development of financial markets and institutions is a critical and inextricable part of the growth process and away from the view that the financial system is an inconsequential sideshow responding passively to economic growth many gaps remain however and the paper highlights areas in acute need of additional research
