estimating sectoral and geographical industrial pollution inventories in india implications for using effluent charge versus regulation developing countries are increasingly concerned about the growing pollution levels in cities because of the lack of reliable information on the nature and magnitude of emissions discharges from various industrial sources it is difficult for regulators to formulate cost effective strategies for industrial pollution control this article uses the industrial pollution projection system database to estimate the industrial pollution load and the associated abatement cost which can be used to design cost effective strategies for pollution control the article also illustrates the cost effectiveness of market based instruments such as effluent charge vis a vis regulation

forward looking assessment of the ghg abatement cost application to china abstract evaluation of abatement costs is critical in setting reduction goals and devising climate policy however reliable forward looking assessment of the short term effects of climate policy remains a major challenge using panel data of 30 chinese provinces during 1997 2015 we first estimate the marginal co2 abatement costs using a novel data driven approach convex quantile regression based on the marginal abatement cost estimates and china s plans regarding carbon intensity reduction and economic growth we present a forward looking assessment of the abatement costs for chinese provinces for 2016 2020 our main finding is that all the chinese provinces have a negative abatement cost which means these provinces can benefit from an increase in the absolute level of co2 emissions despite the constraint on carbon intensity the magnitudes of economic benefits exhibit a significant regional disparity because some provinces can increase more co2 emissions than others however there is still costly carbon intensity abatement relative to a counterfactual where the provinces meet their economic growth targets but in the absence of the intensity reduction constraints policy implications have been proposed to enhance the efficiency and fairness of climate policy in china

why voluntary export restraints are voluntary the paper presents an analysis of the effect upon an oligopolistic equilibrium of introducing a voluntary export restraint ver upon an importing firm a ver set at the free trade level of imports is shown to raise the profits of all firms within the industry the result follows as the imposition of a ver upon a free trade nash price competition forces the domestic firm to become an industry price leader the ver raises industry prices by facilitating collusion and lowers consumer welfare pourquoi les restrictions volontaires d 1 exportation sont volontaires ce memoire presente une analyse des effets de l introduction de restrictions volontaires a l exportation rve sur une entreprise qui importe dans un monde en equilibre oligopolistique on montre que l introduction de rve approximant le niveau des importations en regime de libre echange devrait augmenter les profits de toutes les entreprises dans l industrie cela decoule du fait que l imposition de rve sur un univers de concurrence par les prix a la nash en regime de libre echange force l entreprise domestique a devenir le leader en prix l introduction de rve augmente le niveau des prix de l industrie en facilitant la collusion et de ce fait reduit le niveau de bien etre des consomrnateurs

ethnicity neighborhoods and human capital externalities the socioeconomic performance of today s workers depends not only on parental skills but also on the average skills of the ethnic group in the parents generation or ethnic capital this paper investigates the link between the ethnic externality and ethnic neighborhoods the evidence indicates that residential segregation and the external effect of ethnicity are linked partly because ethnic capital summarizes the socioeconomic background of the neighborhood where the children were raised ethnicity has an external effect even among persons who grow up in the same neighborhood when children are exposed frequently to persons who share the same ethnic background copyright 1995 by american economic association

environmental regulations and industrial competitiveness evidence from china economic activities are closely related to real world environmental issues currently more attention is paid to the association between environmental regulations and industrial competitiveness ic because of pressures on economic development and environmental protection in this study we identify and explain the association between environmental regulations and ic in china as the largest developing country in the world china has the unavoidable responsibility of protecting the environment and promoting global economic development we analyse the mechanisms behind environmental regulations and industrial competiveness at the provincial level and conclude that the impact of environmental regulations upon ic is not a simple linear one but a u shaped relationship it is argued that the crucial intervention to activate the u shaped relationship or porter s hypothesis is innovation which can be triggered by stringent regulations and well designed policies

the impact and economic cost of environmental regulation on energy utilization in china this article utilizes three data envelopment analysis based models a no environmental regulation model a weak environmental regulation model and a strong environmental regulation model to reveal the impact of environmental regulation on china s regional total factor energy efficiency tfee during the period of 2003 2010 to take a further step these three models are adjusted for calculating the correspondingly macro economic cost of environmental regulation the estimation results show that at present the level of china s environmental regulation is relatively low and an enhancing of environmental regulation would lead to a sufficient increase of china s regional tfee with an enormous economic cost as its price that means in china the nationwide environmental stress is high and the regulation cost is very huge strengthening environmental regulation would inevitably have some negative influences on china s economy in the short run based on our findings some corresponding policies are also propo

public versus private investment in human capital endogenous growth and income inequality in this paper we present an overlapping generations model with heterogeneous agents in which human capital investment through formal schooling is the engine of growth we use simple functional forms for preferences technologies and income distribution to highlight the distinction between economies with public education and those with private education we find that income inequality declines more quickly under public education on the other hand private education yields greater per capita incomes unless the initial income inequality is sufficiently high we also find that societies will choose public education if a majority of agents have incomes below average

social networks and technology adoption in northern mozambique despite their potentially strong impact on poverty agricultural innovations are often adopted slowly using a unique household dataset on sunflower adoption in mozambique we analyse whether and how individual adoption decisions depend upon the choices of others in the same social networks since farmers anticipate that they will share information with others we expect farmers to be more likely to adopt when they know many other adopters dynamic considerations however suggest that farmers who know many adopters might strategically delay adoption to free ride on the information gathered by others we present empirical evidence that shows that the relationship between the probability of adoption and the number of known adopters is shaped as an inverse u in line with information sharing the network effect is stronger for farmers who report discussing agriculture with others the data contains information which is needed to ameliorate the identification issues that commonly arise in this context in particular social networks are precisely identified and in addition we can control for village heterogeneity and endogenous group formation

optimal debt endogenous fertility and human capital externalities in a model with altruistic bequests abstract this paper explores optimal debt in a model with altruistic bequests endogenous fertility and human capital externalities because of such externalities education investment is too low and fertility is too high while education subsidies are the conventional means to deal with these problems we show that the optimal policy also comprises debt even when distortionary taxes are used the reason is that debt tips the usual trade off between children s quantity and quality in favor of the latter by increasing the bequest cost of children the optimal debt output ratio exceeds 10 for plausible parameterization

locally interdependent preferences in a general equilibrium environment abstract this paper explores the consequences of interdependent preferences for consumer goods that is preferences that evolve in response to the consumption decisions of neighboring agents the key feature is that the interdependence of preferences coexists and interacts with the price mechanism in a general equilibrium environment the interaction between the negative feedback operating through the price system and the positive feedback expressed in the bandwagon effect creates distinct geographic patterns of consumption on the micro level and a characteristic evolution of average preferences and production on the macro level in equilibrium agents preferences and consumption are completely polarized into stable regions in which every agent consumes the same good exclusively

export restraints in a model of trade with capital accumulation abstract this paper examines the impact of voluntary export restraints vers in an international duopoly modeled as a differential game with a ramsey capital accumulation dynamics the game admits multiple steady states and a ver cannot be voluntarily employed by the foreign firm in case of cournot behavior in demand substitutes hence the dynamic framework confirms the results of the vers literature with static interaction in output levels in the case of price behavior the adoption of an export restraint may increase the profits of both firms if products are substitutes and the steady state is market driven however contrary to the acquired wisdom based upon the static approach the dynamic analysis also admits an equilibrium outcome identified by the ramsey golden rule where the incentive to adopt a ver is ruled out irrespective of whether firms are quantity or price setters

distributional effects of public education in an economy with public pensions we study how the allocation of government expenditures between two major outlays education and pay as you go social security affects human capital distribution in an economy with heterogeneous agents we consider an overlapping generations economy where the government maintains both programs and allocates tax revenues to finance them in our model human capital is one of the factors of production it is itself produced as a combined result of public inputs and private inputs parents decisions to invest time and material resources in education of their children are motivated by altruism heterogeneous in its strength across the population which leads to heterogeneity of incomes we investigate the effect of an increase in public funding for education on the human capital distribution we show that in this framework contrary to some earlier results increased spending on public education may lead to higher inequality our results depend crucially on the interaction of education funding with the social security budget and on the elasticity of substitution in the learning technology

productivity and environmental regulation the effect of the nitrates directive in the french pig sector this paper measures the ensuing changes in productivity in the french pig sector following the introduction of the european regulation addressing water pollution by nitrates from agriculture productivity is measured using the malmquist luenberger index the sources of changes in productivity observed are examined by breaking down this index into its technical progress and efficiency components the results show that in the early stages increases in productivity were stimulated by increased efficiency before being driven by technical progress the estimations regarding the sources of efficiency gains for the farms in the sample technical efficiency efficiency of scale and environmental efficiency are then used to estimate the indirect costs and benefits or negative costs linked to the introduction of the environmental regulation controlling the disposal of organic manure and the management of nitrogen surplus from pig farms the existence of a win win effect as regards the porter hypothesis relation between efficiency and environmental regulation is highlighted for the french pig sector

productivity growth technical progress and efficiency in their comment subhash c ray and evangelia desli 1997 hereafter rd point out that the specification of the decomposition of the malmquist productivity index used by fare et al 1994 hereafter fgnz is not unique and propose and compute an alternative specification of that decomposition we will discuss additional decompositions at the end of this note but proceed here by comparing the rd decomposition with fgnz based on both conceptual and computational grounds rd provide a discussion of the overall malmquist productivity index including the important issue of when this index is equivalent to the traditional notion of total factor productivity tfp namely under the condition that the reference technology be consistent with constant returns to scale crs as they point out this will yield a measure of tfp even if the true underlying technology is not crs for example both rd and fgnz use the crs reference technology to compute overall malmquist productivity one of the key issues raised is the role of the underlying scale properties of the benchmark technologies used to define and compute both productivity and its components in particular two reference technologies are employed in both rd and fgnz what we refer to as crs and variable returns to scale vrs technologies by construction these technologies are nested the crs technology contains the vrs technology as in figure 1 in rd this nestedness provides the logical basis for our decomposition at a very intuitive level we would argue that these two benchmarks can be used to provide bounds on the underlying true but unknown technology 2 intuitively we see the vrs technology providing a type of convex inner approximation whereas the crs technology provides a type of convex outer approximation thus these two technologies provide alternative benchmarks they do not require that the data satisfy either crs or vrs another possible intuitive interpretation is that the crs captures a perhaps hypothetical long run and the vrs approximates the short run as a reference technology the crs technology has some very useful features for example it captures the notion of maximal

estimating the marginal abatement cost curve of co2 emissions in china provincial panel data analysis abstract this paper estimates the marginal abatement cost curve macc of co2 emissions in china based on a provincial panel for the period of 2001 2010 the provincial marginal abatement cost mac of co2 emissions is estimated using a parameterized directional output distance function four types of model specifications are applied to fit the mac carbon intensity pairs the optimal specification controlling for various covariates is identified econometrically a scenario simulation of china s 40 45 carbon intensity reduction based on our macc is illustrated our simulation results show that china would incur a 559 623 yuan t roughly 51 57 increase in marginal abatement cost to achieve a corresponding 40 45 reduction in carbon intensity compared to its 2005 level

shadow pricing of undesirable outputs in nonparametric analysis abstract for three decades a growing interest in the modeling of desirable and undesirable outputs has led to a theoretical and methodological debate in the nonparametric literature on production technology and efficiency the first main discussion is about the way of modeling bad undesirables as inputs or outputs or by transformation functions the second debate concerns the implications of the weak disposability assumption in the modeling of bad outputs in particular the possibility of assigning unexpected signs to shadow prices of bad outputs in addition we point out a current error in the modeling of weak disposability under a variable returns to scale technology in this paper we introduce a hybrid model to ensure the economically meaningful jointness of good and bad outputs while constraining shadow prices of bad outputs to their expected sign we argue that it is a sound compromise to model undesirable outputs with a meaningful primal dual economic interpretation finally we propose an extension to define shadow prices for undesirable outputs following the law of one price loop rule

productivity gains from geographic concentration of human capital evidence from the cities abstract based on recent theoretical developments the argument is made that the average level of human capital is a local public good cities with higher average levels of human capital should therefore have higher wages and higher land rents after conditioning on the characteristics of individual workers and dwellings this prediction is supported by data for standard metropolitan statistical areas smsas in the united states where the smsa average levels of formal education and work experience are used as proxies for the average level of human capital the alternative explanations of omitted smsa variables and self selection are evaluated an estimate of the effect of an additional year of average education on total factor productivity is computed

the evolution of modern educational systems technical vs general education distributional conflict and growth abstract we study the evolution of an educational system founded on a hierarchical differentiation between vocational and general education with vocational playing an inferior role in the society the dynamics are best summarized by the ratio of the fraction of the population in vocational to that in general education which we interpret as a measure of the degree of stratification of the society we show that this ratio first rises and then declines with the level of development displaying an inverted u shape which reflects the complex interaction between economic and political forces including aggregate income growth wealth inequality and political participation

a new approach to measuring shadow price reconciling engineering and economic perspectives abstract shadow price is one of the most important pieces of information in environmental decision making two different approaches namely economic and engineering have been applied to obtain the shadow price of undesirable outputs while using different methodological backgrounds and perspectives the current study proposes a new conceptual framework and an economic estimation model to reconcile the shadow price estimates derived via the two approaches we also suggest a new mapping rule that incorporates the concept of abatement level which is a basic element in the engineering approach as a result the proposed model generates continuously changing estimates i e comprising a shadow price curve based on the abatement level we further investigate the determinant factors of shadow price by using second step regression the suggested methodology is used to investigate the shadow price of carbon emissions in south korean electricity generating plants thus yielding relevant policy implications

centralization fiscal federalism and private school attendance a cge model is used to analyze the impact of public school financing on private school attendance the common perception that public school finance centralization will necessarily lead to greater private school attendance is not correct in such a model even when that centralization involves an extreme equalization as in california furthermore if centralization is less dramatic as in most states declines in private school attendance are even more pronounced this weakens the speculation that low exit rates to private schools in centralizing states imply that general public school quality does not drop as a result of such centralization

tariffs quotas and terms of trade the case of new zealand abstract this paper reports quantitative information on the effects of tariffs and quotas on prices of individual goods the analyses uses the natural experiment provided by a comprehensive unilateral trade policy reform in new zealand to examine the response of foreign exporters to an incident of liberalisation that is unique in the developed world the price effects of tariffs and quotas are estimated using a multidestination 7 digit longitudinal product level dataset on export values and quantities the effects are found to be by no means equivalent whereas tariffs display no significant effect the impact that quantitative restrictions have on the terms of trade of the country that imposes them are unequivocally detrimental and quantitatively important

an empirical analysis of the co2 shadow price in chinese thermal power enterprises abstract this paper estimates the shadow price of co2 and explores its determinants for thermal power enterprises in china using a parametric quadratic directional distance function we evaluate the inefficiency and shadow price of co2 for 124 power enterprises in 2004 applying deterministic and econometric methods a regression analysis is undertaken to examine the factors that drive shadow prices our results indicate that there are large inefficiencies in terms of electricity production and co2 emissions the shadow price is a negative function of firm size age and coal share and is positively correlated with the technology level this correlation between shadow prices and its determinants is not sensitive to changing assumptions regarding directional vectors although such changes do alter the distribution of shadow prices the large variation witnessed in shadow prices across power enterprises argues in favor of market based regulation such as an emissions trading system as opposed to the command and control regulation currently used in china to minimize overall abatement cost

a literature study for dea applied to energy and environment abstract this study systematically summarizes previous research efforts on data envelopment analysis dea applied to energy and environment in the past four decades including concepts and methodologies on dea environmental assessment industrial developments are very important for all nations in terms of their economic prosperities a problem is that the development produces various pollutions on air water and other types of contaminations all of which are usually associated with our health problems and climate changes thus it is necessary for us to consider how to make a balance between economic success and pollution mitigation to maintain a high level of social sustainability in the world it is widely considered that dea is one of the methodologies to examine the level of sustainability this study examines a recent research trend on dea applications from 1980s to 2010s nowadays many researchers have paid serious attention on how to combat various difficulties in the areas of energy and environment as a result the number of articles on dea applications on energy and environment has dramatically increased particularly after 2000s however it is true that dea has strengths and drawbacks in the applications therefore it is very important for us to carefully use dea for guiding large policy issues and business strategies such as the global warming and climate change an underlying premise of this study is that technology innovation in engineering and natural science may solve various problems by linking it with political and managerial efforts the use of dea provides a methodological linkage among them so enhancing the practicality in mitigating problems due to climate change and environmental pollutions this literature study along with a summary on conceptual and methodological developments provides us with guidelines for our future research works on dea on energy and environment issues

malmquist productivity index decompositions a unifying framework in two widely cited but unpublished working papers simar and wilson 1998 and zofio and lovell 1998 proposed an alternative decomposition of the malmquist productivity index which retained what seemed to be the strongholds of previous proposals with regard to the contribution of technological and efficiency change to productivity change namely a technical change term with regard to the best practice variable returns to scale vrs technology which is to be found in ray and desli 1997 and a scale efficiency change term that illustrates a firm s situation with regard to optimal scale benchmark technology fare et al 1994 attaining this objective required the introduction of an additional term in the malmquist productivity index decomposition which would reflect the scale bias of technical change it is our objective to provide economic rationale for this term within a theory of production context the existing decompositions and recent articles that further elaborate on this issue the ide

marginal abatement costs of carbon dioxide emissions in china a parametric analysis this paper investigates the technical inefficiency shadow price and substitution elasticity of hbox co 2 emissions of china based on a provincial panel for 2001 2010 using linear programming to calculate a quadratic parameterized directional output distance function we show that china s technical inefficiency increases over the period implying further scope for hbox co 2 emissions reduction in the medium and longer term at best by 4 5 and 4 9 respectively our results notwithstanding regional differences highlight increases in the shadow price of hbox co 2 abatement 1 000 yuan ton in 2001 to 2 100 yuan ton in 2010 additionally increasingly steep substitution elasticity highlights the difficult reality of reducing china s hbox co 2 emissions

co2 emission abatement cost and its decomposition a directional distance function approach accurately estimating carbon dioxide co2 abatement costs and effectively identifying the factors impacting those costs can improve the applicability and effectiveness of policy implementation this paper proposes a new method to estimate co2 abatement costs cac based on the directional distance function the method theoretically decomposes cac into carbon productivity and output elasticity of substitutions this decomposition can identify the types of cac the method also investigates the effects of development mode selection on cac by selecting different directional vectors following the theoretical discussion an empirical study is presented focusing on high energy consumption firms in the united states u s the results were as follows 1 in sustainable development mode changes in the average cac of all firms were caused both by carbon productivity and output elasticity of substitution carbon productivity dominated cac differences among different firm types 2 in general the amelioration potential of firm technology and environmental management was gradually explored by firms during sample period corresponding environmental regulatory strategies are needed for firms with different cac characteristics 3 firms selecting different development modes will realize significant differences in cac firms in the sustainable development mode had the highest cac levels however this mode was best for achieving a win win between economic benefits and environmental protection

inequality and crime this paper considers the relationship between inequality and crime using data from urban counties the behavior of property and violent crime are quite different inequality has no effect on property crime but a strong and robust impact on violent crime with an elasticity above 0 5 by contrast poverty and police activity have significant effects on property crime but little on violent crime property crime is well explained by the economic theory of crime while violent crime is better explained by strain and social disorganization theories

tightening environmental standards the benefit cost or the no cost paradigm ms ff ichael porter and claas van der linde have written a paper that is interesting and to us at least somewhat astonishing it is a defense of environmental regulation indeed an invitation to more stringent regulation that makes essentially no reference to the social benefits of such regulation this approach contrasts starkly with the methods that economists and other policy analysts have traditionally used when assessing environmental or other regulatory programs the traditional approach consists of comparing the beneficial effects of regulation with the costs that must be borne to secure these benefits for environmental regulation the social benefits include the reductions in morbidity or premature mortality that can accompany cleaner air the enhanced recreational opportunities that can result from water quality improvements the increased land values that might attend the cleanup of a hazardous waste site the enhanced vitality of aquatic ecosystems that might follow reductions in agricultural pesticide use or any of the other potentially significant benefits associated with tighter standards from this benefit cost approach emerges the standard tradeoff discussed in virtually every economics textbook porter and van der linde deny the validity of this approach to the analysis of environmental regulation claiming it to be an artifact of what they see as a static mindset in their view economists have failed to appreciate the capacity of

marginal co2 abatement costs findings from alternative shadow price estimates for shanghai industrial sectors abstract shanghai one of the most developed cities in china is implementing a pilot regional carbon emission trading scheme estimating the marginal abatement costs of co2 emissions for the industrial sectors covered in shanghai s emission trading scheme provides the government and participating firms useful information for devising compliance policies this paper employs multiple distance function approaches to estimating the shadow prices of co2 emissions for shanghai industrial sectors our empirical results show that the overall weighted average of shadow price estimates by different approaches ranges between 394 5 and 1906 1 yuan ton which indicates that model choice truly has a significant effect on the shadow price estimation we have also identified a negative relationship between the shadow price of co2 emissions and carbon intensity and the heavy industries with higher carbon intensities tend to have lower shadow prices it has been suggested that shanghai municipal government take various measures to improve its carbon market e g using the marginal abatement costs of participating sectors firms as a criterion in the initial allocation of carbon emission allowances

sources of production inefficiency and productivity growth in china a global data envelopment analysis abstract the current mode of production in china is extensive and inefficient and has caused great stress on both resources and the environment this paper focuses on analyzing the sources of production inefficiency and productivity growth in china here a developed slacks based measure is utilized to decompose production inefficiency into three components input inefficiency economic output inefficiency and environmental inefficiency furthermore by applying a method based on global data envelopment analysis we take a further step to analyze the key factors responsible for the change of environmental productivity during 2003 2011 from the point of view of technical progress productive scale and management level the results show that redundancy in energy and labor inputs and excessive emission of sulfur dioxide chemical oxygen demand and ammonia nitrogen are the main sources of production inefficiency in china during the sample period the efficiency in all inputs and environmental emissions has improved except for capital input efficiency which had a decreasing trend further analysis shows that the overall environmental productivity in china has begun to follow an ascending path technical progress is the most powerful contributor to china s productivity growth while the decreases in scale and management efficiency are the two main obstacles preventing productivity improvement

the effect of rising income inequality on taxation and public expenditures evidence from u s municipalities and school districts 1970 2000 the income distribution in many developed countries widened dramatically from 1970 to 2000 some scholars argue that income inequality contributes to a host of social ills by undermining voters will ingness to support public expenditures in contrast we find that growing income inequality is associated with an expansion in government reven ues and expenditures on a wide range of services in u s municipalities and school districts results are robust to a number of model specifica tions including instrumental variables that address the endogeneity of the local income distribution our results are inconsistent with models pre dicting that heterogeneous societies provide lower levels of public goods public sector 3 two types of identification problems com plicate estimation of the empirical relationship between income inequality and public goods provision the cross country variation often used for this exercise suffers from omitted variable bias that is countries with high income inequality may also have other characteristics that could limit the size of the public sector cross state comparisons also suffer from endogenous household sorting if low or high income families migrate to states with high public expenditures the positive association observed in the litera ture between state public expenditures and income inequal ity may be spurious in this paper we examine the relationship between income inequality and government finances in municipali ties and school districts in the united states from 1970 to 2000 local government represents a large segment of the economy in fiscal year 2009 local governments disbursed more than 3 trillion for such important services as educa tion and public safety 4 our study has several advantages over existing empirical work first the large number of local governments in our data exhibit much greater variation in income inequality over time than do the small number of countries or states used in previous studies a large sample size allows us to separately control for changes in the top end or bottom end of the income distribution and for initial levels of inequal ity thus ruling out a mechanical association between tax revenues and rising income for the affluent second we develop an instrumental variable strategy to mitigate con cerns about potential reverse causality from the endogenous

multilateral productivity comparisons when some outputs are undesirable a nonparametric approach multilateral productivity comparisons of firms producing multiple outputs some of which are undesirable are obtained by making two modifications to the standard farrell approach to efficiency measurement the restriction that production technology satisfy strong disposability of outputs is relaxed to allow for the fact that undesirable outputs may be freely disposable and the efficiency measures are modified to allow for an asymmetric treatment of desirable and undesirable outputs performance measures that satisfy these requirements are calculated as solutions to programming problems the methodology is applied to a sample of mills producing paper and pollutants

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

vers and expectations extensions and evidence this paper analyses the effects of an expected future voluntary export restraint on the level of firms current exports to a market the traditional result that current exports increase is shown to depend on the degree of collusion in the exporting industry and the anticipated restrictiveness of the ver the former relationship is tested by reference to the effect of ec import surveillance on its imports surveillance is argued to indicate an increased probability of a ver in the future and it is found that while competitive industries respond to it by increasing exports to the ec less competitive ones curtail exports this constitutes one of the few empirical tests of the strategic part of strategic trade policy

marginal abatement costs of carbon dioxide emissions and its influencing factors a global perspective abstract reducing co 2 emissions has become a major and urgent environmental goal worldwide in this paper we sample the data of 41 regions including 165 countries from 2000 to 2014 and adopt a gravity model to obtain an overview of the global flows of co 2 emissions energy consumption the global economy and capital stock since the beginning of the 21st century we then investigate global technical efficiency reduction potential shadow prices and factors influencing the marginal abatement costs of co 2 emissions based on a quadratic directional output distance function the empirical results show the following 1 the global centres of gravity for co 2 emissions energy consumption and capital stock have accelerated their shift to the asian inland in the 21st century but the global centre of gravity for the economy did not show the same trend 2 global technical inefficiency demonstrates a u shape with a turning point in 2007 average annual total global co 2 emissions could be reduced by 4482 28 mt and the global marginal abatement costs of co 2 emissions are approximately 673 74 697 73 usd t 3 the relationship between economic development and marginal abatement costs is represented by a u shaped curve the world is currently in the climbing phase of this curve implying that controlling co 2 emissions is becoming more costly moreover energy structure industrial structure and co 2 emissions are negatively correlated with marginal abatement costs finally the financial crisis has had a significant effect on marginal abatement costs

persistent parochialism trust and exclusion in ethnic networks decentralized groups such as close knit residential neighborhoods and ethnically linked businesses often achieve high levels of cooperation while engaging in exclusionary practices that we call parochialism we investigate the contribution of within group cultural affinity to the ability of parochial groups to cooperate in social dilemmas we analyze parochial networks in which the losses incurred by not trading with outsiders are offset by an enhanced ability to enforce informal contracts by fostering trust among insiders we show that there is a range of degrees of parochialism for which parochial networks can coexist with an anonymous market offering unrestricted trading opportunities

the desegregating effect of school tracking this paper makes the following point detracking schools that is preventing them from allocating students to classes according to their ability may lead to an increase in income residential segregation it does so in a simple model where households care about the school peer group of their children if ability and income are positively correlated tracking implies that some high income households face the choice of either living in the areas where most of the other high income households live and having their child assigned to the low track or instead living in lower income neighbourhoods where their child would be in the high track under mild conditions tracking leads to an equilibrium with partial income desegregation where perfect income segregation would be the only stable outcome without tracking

spillovers stratification and inequality this paper surveys some recent work which seeks to model persistent income inequality and explain such phenomena as ghetto formation and poverty traps the paper illustrates how a number of these models possess a common structure in which local spillover effects interact with income based stratification of neighborhoods to transmit parental economic status from generation to generation as such these models represent an extension of the macroeconomic literature on spillovers and coordination failures to economic environments which endogenize the interaction environments of individual agents the theoretical and empirical justifications of these spillover and stratification effects are discussed finally some empirical implications of these models are analyzed

energy abatement in chinese industry cost evaluation of regulation strategies and allocation alternatives abstract for chinese industry the costs of different energy consumption abatement scenarios are evaluated by the method of directional distance function these scenarios are based on the combinations of regulation strategies and allocation alternatives the former are sectors and provinces and the latter include the five principles of average intensity share absolute share discriminatory absolute and discriminatory intensity for all the scenarios the quantitative impacts in terms of output potential loss are calculated and compared due to less output potential loss for all the allocation alternatives the sector regulation strategy is shown to be more effective than the province regulation strategy it is also demonstrated that among all the scenarios considered the sector regulation based on the intensity share principle and the province regulation based on the absolute share principle are the two optimal the performances of energy abatement allocation of the 11th and 12th five year plans of china are assessed against the simulated scenarios

dynamic instability of a mixed city in the presence of neighborhood externalities it has been often asked whether a city currently accommodating a variety of economic social and racial groups will continue to be a mixed city or will become exclusively occupied by a single group particularly poor blacks with all other groups moving out of the city in the long run in order to answer this question properly it seems essential to develop a long run dynamic model of a city with emphasis on socioeconomic factors like neighborhood externalities within or among various groups of residents as well as spatial factors like the individual choice of residential space and location it might be safely said that in the literature the only theoretical work which employs a long run dynamic approach to this kind of problem is a paper on dynamic models of segregation by thomas schelling 197 1 although his socioeconomic analysis has revealed some of the dynamic properties of a racially mixed area with neighborhood externalities his model itself is quite unsatisfactory from the economic point of view since it lacks individual utility functions and thereby disregards the aspect of the individual choice of space and location within the city 2 as a result he failed to analyze the effect of spatial segregation within the city on the long run nature of the residential composition of the city in this paper i develop a long run dynamic model of an open city which accommodates two groups of households for example blacks and whites rich and poor young and old with their utility functions depending on a consumption good and residential space i also assume two kinds of neighborhood externalities the first is called negative intergroup externalities that is the utility level of a typical household in one group is adversely affected by an increase in the number of households in the other group living in the city the second is called positive intragroup externalities that is the utility level of a typical household in one group is positively affected by an increase in the size of its own group in in the city first i define a mixed city equilibrium as a long run equilibrium which allows the two groups to coexist in the city in the long run and then introduce a dynamic adjustment process of household movement into and out of the city it is proved that the mixed city equilibrium is always unstable in the presence of negative intergroup externalities and or positive intragroup externalities if residential land is perfectly homogeneous and there is no differential transport cost incurred within the city it turns out however that in the case of a monocentric city with positive transport cost the mixed city equilibrium may be stable or unstable depending on the degree of neighborhood externalities because of the stabilizing effect of spatial segregation between the two groups within the city

decomposition of the environmental inefficiency of the meta frontier with undesirable output abstract in this paper we present an alternative analysis framework to evaluate the effects of technology heterogeneities and undesirable output on environmental efficiency measurement the proposed framework combines the directional distance function and a meta frontier analysis it can be used to measure efficiency improvements brought about by enhanced technical management and technological advances for demonstration purposes we used the framework to measure the environmental efficiency in 90 countries worldwide for the 2003 2007 period the results showed that when the meta technology set is used as the evaluation basis the average environmental efficiency of high competitiveness countries is greater than that of lower middle low and upper middle competitiveness countries the upper middle competitiveness countries perform worse than the lower middle and low competitiveness countries because of the excessive labor force usage and carbon dioxide emissions in these countries we also found that the environmental inefficiency of the meta frontier for high competitiveness countries can be attributed to managerial failure in the production process whereas that for upper middle lower middle and low competitiveness countries can be attributed to technological differences

is energy intensity important for the productivity growth of eet adopters abstract energy efficient technologies eet have attracted strong interest because of their role in reducing environmental damage their adoption however remains rather low while their impact on productivity is substantial and differentiating with respect to technological characteristics energy intensity being such an obvious characteristic could be employed to classify eet adopters thus giving rise to two heterogeneous technologies i e those corresponding to firms of low and high energy consumption hence this paper examines the impact of energy intensity on the productivity growth of firms adopting eet in varying time intervals through a metafrontier based framework while also decomposing that impact in terms of technical efficiency and scale efficiency changes the analysis is complemented by examining the role of firm specific characteristics on the productivity growth through linear regression

water pollution abatement by chinese industry cost estimates and policy implications using factory level data provided by china s national environmental protection agency and the tianjin environmental protection bureau the authors of this report estimate the costs of water pollution abatement for chinese industry using their econometric results they analyze the cost effectiveness of current pollution control policy in china and make the conclusions that follow 1 for each pollutant marginal abatement costs exhibit great differences by sector scale and degree of abatement 2 the benefits of stricter discharge standards should be weighed carefully against the costs 3 emissions charges as low as 1 per ton would be sufficient to induce 80 percent abatement of suspended solids chemical oxygen demand and biological oxygen demand respectively 4 the current regulatory system provides an economic incentive to abate by charging a levy on pollution that exceeds the standard the results of this analysis suggest however that changing to a full emissions charge system would greatly reduce overall abatement costs the approach the authors recommend for measuring the costs of abatement is to use joint abatement cost functions that relate total costs to treatment volume and the simultaneous effect of reductions in suspended solids chemical oxygen demand biological oxygen demand and other pollutants tests of alternative functional forms suggest that a simple constant elasticity model fits the data as well as a complex translog model does permitting sophisticated policy experiments with relatively simple calculations

a spatial temporal model of human capital accumulation abstract we develop an overlapping generations model of human capital accumulation and analyze its spatial and temporal properties the interplay between local spillovers of human capital and global market participation partitions the society into socio economic classes we focus upon stationary equilibria and show that a large class of them are locally stable stationary equilibria can be homogeneous where the human capital distribution is degenerate or stratified with a distinct spatial pattern of human capital distribution we provide several examples and specify conditions under which equilibria are sensitive to the spatial structure of the society we illustrate our results by numerical simulations journal of economic literature classification numbers d90 i21 j24 o15

which policy is more effective carbon reduction in all industries or in high energy consuming industries from dual perspectives of welfare effects and economic effects abstract carbon emission reduction policy is the main method to curb carbon emissions and tackle climate change however few studies have investigated the effectiveness of carbon emission reduction polices from the welfare and economic perspectives this study establishes a dynamic general equilibrium model with input output structure and compares the effects of emission reduction in all industries and in high energy consuming industries the main conclusions are that carbon emission reduction constraints for all industries have more significant negative impacts on consumption and social welfare compared to emission reduction constraints for high energy consuming industries to be more precisely carbon emission reduction in high energy consuming industries has comparative advantages in maintaining social welfare stability regarding economic effects compared with the carbon emission reduction in high energy consuming industries carbon emission reduction in all industries leads to a larger decline in total output and outputs of most industries however the role of carbon emission reduction in all industries is more significant in promoting employment the carbon emission reduction policies of all industries and high energy consuming industries have strengths in economic effects respectively the findings could provide references for the government to take appropriate measures to promote carbon emission reduction and economic growth

the closed loop motive for voluntary export restraints this paper examines the effects of voluntary export restraints in a dynamic game model of duopolistic competition it is shown that the imposition of a voluntary export restraint at the free trade level of imports increases the market price and the profits of all firms in the industry if free trade is identified as the closed loop subgame perfect cournot equilibrium of the game hence the authors conclude that the predictions of static cournot competition do not carry over to the dynamic case

equity and efficiency in human capital investment the local connection a general model of community formation and human capital accumulation with social spillovers and decentralized school funding is used to analyse the causes of economic segregation and its consequences for equity and efficiency significant polarization arises from minor differences in endowments preferences or access to capital markets this makes income inequality more persistent across generations but the same need not be true for wealth equilibrium stratification tends to be excessive resulting in low aggregate surplus whether state equalization of school resources can remedy these problems hinges on how purchased social and family inputs interact in education and in mobility decisions

ethnic capital and intergenerational mobility this paper analyzes the extent to which ethnic skill differentials are transmitted across generations i assume that ethnicity acts as an externality in the human capital accumulation process the skills of the next generation depend on parental inputs and on the quality of the ethnic environment in which parents make their investments or ethnic capital the empirical evidence reveals that the skills of today s generation depend not only on the skills of their parents but also on the average skills of the ethnic group in the parent s generation

more equal but less mobile education financing and intergenerational mobility in italy and in the us a centralised and egalitarian school system reduces the cost of education for poor families and so it should reduce income inequality and make intergenerational mobility easier in this paper we provide evidence that italy compared to the usa displays less income inequality as expected given the type of school system but also less intergenera tional upward mobility between occupations and between education levels we explore some of the reasons which can explain this puzzling result and conclude that in a world in which family background is important for labor market success a centralised and egalitarian tertiary education does not necessarily help poor children and may take away from them a fundamental tool to prove their talent and to compete with rich children 1999 elsevier science s a all rights reserved

why voluntary export restraints are voluntary an extension this paper presents a conjectural variation approach to examine the conditions under which voluntary export restraints are voluntary th e authors have shown that the value of the conjectural variation is a critical factor for determining the effects of voluntary export restraints in particular if the free trade equilibrium is more collusive than cournot the imposition of voluntary export restraints at the free trade level of imports leads to a reduction in the profit of the foreign firm unde r such circumstances voluntary export restraints are involuntary which is contrary to r harris s 1985 assertion

efficient equilibrium convergence heterogeneity and growth abstract an endogenous growth model arising from task specialization is used to examine the effects of differing initial human capital distributions two macroeconomic phenomena are produced income convergence and leapfrogging of living standards income convergence occurs for all countries in the same market arising from diminishing returns to individual human capital leapfrogging occurs by comparing countries in two separate markets income leapfrogging can occur because the stationary growth rate increases with market size and human capital heterogeneity reduces growth the introduction of coordination costs of task assignment can produce gains in welfare and growth from human capital heterogeneity

equilibrium and inefficiency in a community model with peer group effects public service output depends on input expenditures on own personal characteristics and on the characteristics of the other residents in the community the peer group effect in a community model with public expenditures set by voting with migration between communities and with land price differentials capitalization it is shown that communities may become heterogeneous in composition and second best inefficient this equilibrium occurs when the peer group effect is neither too strong nor too weak the inefficiency arises because an externality is created by migration the land price differential does not play the part of the price of the better peer group but of a transfer payment

honey i shrunk the kids benefits revisiting intergenerational conflict in oecd countries intergenerational conflict may arise when the interests of different age groups do not align we examine cross country data to find evidence for this conflict in oecd countries we derive our results from a fgls estimation model which is complemented by a system gmm estimation to account for potential endogeneity the data are from a panel of 22 oecd countries over the time period 1985 2005 we find little support for intergenerational conflict in general however those who are close to statutory retirement age dislike public expenditure on families and education because once they retire they will have less income compared to their work income this effect is transitory however implying a change in voting behavior during retirement age

assessing the impact of formal and informal regulations on environmental and economic performance of brazilian manufacturing firms this study investigates the impact of formal and informal regulations on environmental and economic performance of brazilian manufacturing firms we adopt a dual approach where production technology is represented by a cost function approximated by a translog form pollution is considered as a negative by product that can be modified trough using either formal regulation inspections or sanctions or informal regulation community pressure a simultaneous equation model is estimated by three stage least squares on a sample of 404 industrial establishments located in the state of sao paulo brazil we show that pollution abatement costs for the brazilian manufacturing sector are different from zero which suggests that pollution emissions are affected by environmental regulation we also demonstrate that environmental performance of firms is jointly affected by formal and informal regulation lastly formal regulation is largely influenced by informal regulation and more specifically by community pressure

the evolution of human capital in an interacting agent economy abstract we consider a dynamic spatial model of human capital accumulation in the presence of local spillovers in learning our results provide conditions under which homogeneous and heterogeneous steady states exist and are locally stable our model also considers the impact of role models and mentors and indicates when they can have a positive or negative impact upon the steady state human capital levels we also show that in some circumstances the dynamics of human capital accumulation can be chaotic

keeping one step ahead of the joneses status the distribution of wealth and long run growth assuming that the utility of each agent depends on its relative wealth position in the society this chapter constructs an endogenous growth model it is shown that even if the subjective discount rates differ across agents there exists a unique balanced growth equilibrium in which each agent owns a positive share of the world wealth it is also shown that if the agents are identical then an increase in savings incentives always raises the long run growth rate but if they are heterogeneous then an increase in savings incentives may lower the long run growth rate

increasing agricultural productivity while reducing greenhouse gas emissions in sub saharan africa myth or reality the motivation for this study stems from two major concerns that are interlinked the first is the decades long food insecurity crisis faced by sub saharan african ssa countries which is still prevalent the second is the negative impact greenhouse gas ghg emissions from agriculture may have on future food production and which is likely to worsen the food insecurity problem the conundrum ssa farmers face is how to increase food output through productivity growth while minimizing ghg emissions to measure changes in productivity growth and ghg emissions this study evaluates the agricultural performance of 18 ssa countries by utilizing the malmquist luenberger index to incorporate good and bad outputs for the years 1980 2012 the empirical evidence demonstrates that productivity is overestimated when bad outputs are not considered in the production model the analysis provides a better understanding of the effectiveness of previous mitigation methods and which informs an appropriate course of action needed to achieve the twin objectives of increasing agriculture productivity while reducing ghg emissions

industrial natural gas consumption in the united states an empirical model for evaluating future trends abstract this study develops a statistical model of industrial us natural gas consumption based upon historical data for the 1958 2003 period the model specifically addresses interfuel substitution possibilities and changes in the industrial economic base using a relatively simple approach the framework can be simulated repeatedly with little effort over a range of different conditions it may also provide a valuable input into larger modeling exercises where an organization wants to determine long run natural gas prices based upon supply and demand conditions projections based upon this demand framework indicate that industrial natural gas consumption may grow more slowly over the next 20 yr than being projected by the u s energy information administration eia this conclusion is based upon the assumption that natural gas prices will follow oil prices as they have done over recent decades if natural gas prices should lag well below oil prices as envisioned by the latest eia outlook industrial natural gas consumption should rapidly expand well beyond the levels being projected by eia

green productivity growth in china s industrial economy abstract this paper uses a directional distance function ddf and the malmquist luenberger productivity index to estimate the changing patterns of green total factor productivity gtfp growth of 38 chinese industrial sectors during the period 1980 2010 unlike the measures of traditional total factor productivity tfp growth the ddf incorporates carbon dioxide emissions as an undesirable output directly into the production technology which credit sectors for simultaneously reducing their emissions and increasing their output our estimates of aggregate and sector level gtfp growth reveal that chinese industry is not yet on the path towards sustainable low carbon growth a dynamic panel data analysis of the determinants of gtfp across sectors is used to identify factors that might rectify this situation including state owned enterprise soe reform the growth of small private enterprises continued openness to foreign investment and higher spending on r d particularly in emission intensive sectors

productivity growth and environmental regulations accounting for undesirable outputs analysis of china s thirty provincial regions using the malmquist luenberger index this paper employs the malmquist luenberger ml productivity index to evaluate china s growth in total factor productivity tfp incorporating undesirable outputs during the period from 1989 to 2008 the ml productivity index and its components technical and efficiency changes are derived from the directional distance function which gives credit for an increase in good outputs and for reductions in undesirable outputs the average annual ml productivity growth accounting for undesirable outputs is 2 46 whereas the value of the traditional malmquist productivity index is 4 84 showing that the true tfp growth in china is overestimated if undesirable outputs are ignored we explore the strictness in enforcing environmental regulations and its impact on improvements in ml productivity the results show that the enforcement of environmental regulations in china is in general far below the levels achieved in the best performing regions and that the more stringent enforcement of environmental regulations would help to improve ml productivity growth in china

neighborhood income distributions this paper studies the distribution of income within neighborhoods and contrasts it with the national income distribution it relies on a unique feature of the american housing survey whose 1985 1989 and 1993 waves of interviews provide data for small residential neighborhoods these consist of a dwelling unit and up to ten of its nearest neighbors most previous work on neighborhoods has used information for much larger groupings of the population such as census tracts the paper employs a variety of parametric and nonparametric econometric tools to study income sorting across us residential neighborhoods it documents the patterns of dependence among neighbors income and imperfect sorting with moderate but very significant correlation among incomes of neighbors and of considerable income mixing in u s neighborhoods

distributive politics and economic growth a crude distinction between economics and politics would be that economics is concerned with expanding the pie while politics is about distributing it in this paper we analyze the relationship between the two we focus on how an economy s initial configuration of resources shapes the political struggle for income and wealth distribution and how that in turn affects long run growth our main conclusion is that inequality is conducive to the adoption of growth retarding policies we derive this result from a simple political economy model of growth and present cross country evidence consistent with it the key feature of our model is that individuals differ in their relative factor endowments we distinguish between two types of factors an accumulated factor called capital and a nonaccumulated factor called labor growth is driven by the expansion of the capital stock which is in turn determined by individual saving decisions long run growth is endogenous as the aggregate production function is taken to be linearly homogeneous in capital and productive government services taken together the provision of government services is financed by a tax on capital because government services are productive a small tax on

a dea approach for estimating the agricultural energy and environmental efficiency of eu countries this study attempts to evaluate the energy and environmental efficiency of the primary sectors of the eu member state countries the evaluation is based on a non radial data envelopment analysis dea model which allows for non proportional adjustments to energy inputs and undesirable outputs and thus it provides different estimations for energy and environmental efficiency scores the 2001 2008 time period was selected for this research one of the most important findings is that countries like germany sweden or austria with strong environmental protection standards appear to be less energy and environmentally efficient compared with countries like denmark belgium spain france or ireland in addition a series of eastern european countries achieve low efficiency scores which can be characterized as expectable due to low technology level being implemented in the primary production process there are also two sub periods for this research the first one 2001 2006 covers the fully coupled with specific cultivations period for subsidy administation and the second 2007 2008 where the new decoupled subsidy scheme was implemented there are significant hints for considerable changes of energy and environmental efficiency after the implementation of the the new cap with the new member states siginificantly differ of both energy and environmental efficiency copmared with the older ones

productivity growth technical progress and efficiency change in industrialized countries this paper analyzes productivity growth in 17 oecd countries over the period 1979 1988 a nonparametric programming method activity analysis is used to compute malmquist productivity indexes these are decomposed into two component measures namely technical change and efficiency change we find that u s productivity growth is slightly higher than average all of which is due to technical change japan s productivity growth is the highest in the sample with almost half due to efficiency change jel c43 d24 in this paper we apply recently developed

the intergenerational conflict over the provision of public education abstract we study the intergenerational conflict over the provision of public education this conflict arises because older households without children have weaker incentives to support the provision of high quality educational services in a community than younger households with school age children we develop an overlapping generations model for households in a system of multiple jurisdictions this model captures the differences in preferred policies over the life cycle we show that the observed inequality in educational policies across communities is not only the outcome of stratification by income but is also determined by the stratification by age and a political process that is dominated by older voters in many urban communities with low quality of educational services the mobility of older households creates a positive fiscal externality since it creates a larger tax base per student this positive tax externality can dominate the negative effects that arise because older households tend to vote for lower educational expenditures as a consequence sorting by age can reduce the inequality in educational outcomes that is driven by income sorting

trade liberalization and environmental degradation in china being aware that trade liberalization affects the environment by scale technique and composition effects this study uses provincial data from 1993 to 2002 in china to empirically investigate how they affect the environment adopting the methodology provided by antweiler et al 2001 and slightly modifying their model this study examines whether the composition effects arising from increasing trade originate due to differences in capital labour endowment factor endowment hypothesis and or differences in environmental regulations accompanied by income growth pollution haven hypothesis in china the results indicate that the evidence of factor endowment hypothesis is found in most of the pollutants studied in this article whilst there seems no evidence of pollution haven hypothesis combining with all the estimated elasticities of scale and technique effects composition effects and trade intensity on emissions i find that increasing international trade has opposite impacts on the environment due t

heterogeneity stratification and growth macroeconomic implications of community structure and school finance this paper examines how socioeconomic stratification and alternative systems of education finance affect inequality and growth agents interact through local public goods or externalities school funding neighborhood effects and economywide linkages complementary skills knowledge spillovers sorting families into homogeneous communities often minimizes the costs of existing heterogeneity but mixing reduces heterogeneity faster integration therefore tends to slow down growth in the short run yet raise it in the long run a move to state funding of education presents society with a similar intertemporal trade off local and global complementarities play major roles in determining the efficient social and educational structures copyright 1996 by american economic association

slacks based efficiency measures for modeling environmental performance we develop two slacks based efficiency measures for modeling environmental performance on the basis of environmental dea technology of the two measures one is a composite index with a higher discriminating power for modeling economic environmental performance and the other can be used to estimate the impacts of environmental regulations we apply the proposed measures to model the co2 emissions of 30 oecd countries from 1998 to 2002 and present the results obtained

interregional redistribution and mobility in federations a positive approach the paper studies the effects and the determinants of interregional redistribution in a model of residential and political choice we find that paradoxical consequences of inter jurisdictional transfers arise if people are mobile while self sufficient regions are nec essarily identical with respect to policies and average incomes in our model interregional redistribution always leads to the divergence of regional policies and per capita incomes thus interregional redistribution prevents interregional equality at the same time however transfers may allow for more interpersonal equality among the inhabitants of each region the voting population may therefore in a decision over the fiscal constitution deliberately implement such a transfer scheme to foster regional divergence empirical evidence from panel data from oecd countries and candian provinces is consistent with the theory

effects of family and community background on economic status policy oriented discussions of poverty in the united states repeatedly have stressed the large influence of family and community background on income status in this paper we use a simple statistical model to explain how problems of measurement error and unrepresentative samples have caused previous statistical studies to underestimate the magnitude of background effects we then summarize a series of our own studies in which we have corrected for the biases in earlier studies and estimated substantially larger background effects the empirical analysis is based on data from the panel study of income dynamics excerpt
