who would be left behind by enhanced private school choice abstract debate over school choice is central to many discussions of public elementary and secondary educational reform the debate has largely focused on conceptual arguments rather than careful empirical research that attempts to sort out competing claims an important unresolved issue is the question of cream skimming who will move and who will be left behind as a result of enhanced school choice this paper uses data from the national educational longitudinal survey nels 88 to estimate a model of public private school choice which is used to simulate who would likely leave public schools as a result of enhanced private school choice building upon the work of k train et al 1987 the review of economics and statistics 69 383 391 we employ a probit model with latent explanatory variables to account for the unobserved attitudes of parents and their children regarding education the model allows us to consider such latent interests in education as well as the academic and socioeconomic characteristics of those students who would likely switch to private schools our findings indicate that concerns about bright flight or academic cream skimming in response to increased school choice appear to be overstated however we estimate that there would be substantially more economic and racial segregation of students as movers tend to be white and have higher incomes than those who are left behind

transfers to sustain dynamic core theoretic cooperation in international stock pollutant control international environmental agreements aiming at correcting negative externalities generated by transboundary pollution are difficult to achieve for many reasons important obstacles arise from asymmetry in costs and benefits and instability may occur due to the fact that coalitions of countries may attempt to do better for themselves outside of any proposed agreement in a static context it has already been shown that it is possible to achieve stability in the sense of the core of a co operative game by means of appropriately defined transfers between the countries involved however the transboundary pollution problems that are most important are caused by accumulated pollutants so that a dynamic analysis is required this paper provides a transfer scheme that yields a core property in a dynamic context the possibility of computing such transfers numerically is discussed

buying their votes a study of local tax price discrimination i introduction financial support for public schools in developed countries has recently been declining as governments face increasing pressure to balance their budgets by reducing expenditures on public services public school revenues may be particularly vulnerable in countries where elderly residents will compose a rising share of the population while the percent of united states residents over the age of 65 was 12 4 in 2000 the u s census bureau 2008 predicts this will rise to 16 3 by 2020 and 20 7 by 2050 recent growth in the upper middle aged population ages 55 64 has occurred throughout the united states and if current trends continue communities with the largest growth in the elderly share ages 65 and over over the next 30 years will experience this growth primarily due to aging in place rather than residential migration frey 2007 the typical school district will thus have an increasing share of adults who do not consume public schooling services this trend could have two important implications for school districts 1 decreased political support for school expenditures and 2 a greater tax base per student due to a reduction in the relative size of the school aged population if the former effect dominates the latter then local district revenues per student will decline this dynamic would be consistent with prior u s trends figlio and fletcher 2012 find that most of the within metropolitan area variation in suburbs age distributions in 1980 and 1990 can be traced back to these suburbs age distributions when adults settled there in earlier decades those authors simulate the shares of elderly adults residing in various suburbs based on the aging in place of early residents and their simulated elderly shares are negatively correlated with suburban school expenditures state or federal governments could potentially alter this dynamic by subsidizing local property tax reductions that are targeted toward elderly homeowners elderly homeowners receiving these reductions might support higher levels of local public school spending because they can maintain high property values at a relatively low cost in other words elderly homeowners preferred level of local tax revenues may be sensitive to their marginal local tax price the change in their tax payments required to increase local school district revenues by one dollar by influencing elderly homeowners preferred local tax rates targeted tax price reductions may shift the identity of the local median voter and thus moderate how changes in demographics affect local public revenue this article is the first to empirically examine whether targeted tax price reductions moderate the impact of age demographics on local government revenues prior studies examined how the aging in place of local populations affects public school revenues figlio and fletcher 2012 harris evans and schwab 2001 ladd and murray 2001 and this article tests whether there is important within sample heterogeneity in these effects using similar methods as these prior studies the empirical models below isolate the exogenous component of changes in local age demographics by using lagged population shares as instrumental variables predicting future age demographics to test for heterogeneous effects i assembled a longitudinal data set concerning states property tax reduction policies for elderly homeowners the results confirm earlier studies findings that exogenous increases in the fraction of elderly residents ages 65 and over on average decrease tax revenues in u s school districts however state financed reductions in elderly homeowners marginal local tax prices significantly reduce the negative effect of the local elderly population share this negative effect is only large in communities not offering any targeted local tax price reductions to elderly homeowners significant differences in the effects of the elderly share across state policy regimes are robust to several alternative empirical specifications including comparisons of school districts that are located near each other on opposite sides of state borders

skill biased technological change and rising wage inequality some problems and puzzles the recent rise in wage inequality is usually attributed to skill biased technical change sbtc associated with new computer technologies we review the evidence for this hypothesis focusing on the implications of sbtc for overall wage inequality and for changes in wage differentials between groups a key problem for the sbtc hypothesis is that wage inequality stabilized in the 1990s despite continuing advances in computer technology sbtc also fails to explain the evolution of other dimensions of wage inequality including the gender and racial wage gaps and the age gradient in the return to education

micro estimates of public spending demand functions and tests of the tiebout and median voter hypotheses responses to questions given to a random sample of michigan households are used to estimate public spending demand functions while income and price elasticities are similar to those obtained from aggregate data positive income elasticities appear to arise because public services are distributed in a prorich manner a relatively small variance in spending demands among urban and suburban communities in metropolitan areas with substantial public service variety suggests that the tiebout mechanism works this interpretation is supported by the fact that actual spending conforms substantially to desired levels in urban areas but less so in rural areas with little public sector choice

efficiency and equity in the provision of public education the paper focuses on the benefits derived from public elementary and secondary education monetary values of households perceived benefits from operating expenditures are estimated information concerning the preference mappings of citizens is obtained using a random utility model to analyze micro voting data the estimated model in turn provides information concerning the efficiency and distributional consequences of public education expenditures the conclusion is that operating expenditures exceed the estimated efficient level furthermore it may be difficult to justify the inefficiently large expenditures on equity grounds since the estimated distribution of households perceived benefits net of local taxes is pro rich g overnment provision of goods and i j services has the potential of greatly affecting the welfare of citizens this paper focuses on the benefits derived from one such service public elementary and secondary education monetary values of households perceived benefits from public education expenditures are estimated information concerning the preference mappings of citizens is obtained using a multinomial probit random utility model to analyze micro voting data the estimated model in turn provides information concerning the efficiency and distributional consequences of public education expenditures the conclusion is that operating expenditures exceed the estimated efficient level furthermore it may be difficult to justify the inefficiently large expenditures on equity grounds since the estimated distribution of households perceived benefits net of local taxes is pro rich in contrast to this study a number of studies employ ad hoc rules to measure citizens benefits from public elementary and secondary education initially total benefits are assumed to equal the cost of educational services this input cost measure of benefits is then allocated to households using some unproven rule of thumb when an ad hoc rule is used to allocate a questionable measure of total benefits the results are even more suspect conceptually it is quite odd to determine assume total benefits and then allocate the total to individuals or households the correct method is first to obtain estimates of individuals or households benefits these estimates can then be used to determine the magnitude of total benefits and analyze how the benefits are distributed across the population aaron and mcguire 1970 criticize ad hoc benefit measures and propose the income value measure for x units of the politically allocated good x this measure is iv mrsj x where mrsj is the marginal rate of substitution of x for a composite commodity evaluated at x and one s aftertax income this measure is comparable to measures of the income values of goods purchased in private markets while aaron and mcguire argue for preferencebased benefit measures the lack of information concerning preference mappings necessitates that they assume the shape of the utility function even though the results by maital 1973 based on a similar method are slightly less restrictive a number of restrictive assumptions are common to both studies not only are households assumed to have identical separable utility functions but the existing levels of politically allocated goods are assumed to be efficient implying the total income value equals the input cost also the allocation of benefits from mixed goods e g public education between public and private components is based on ad hoc rules the major contribution of the current study is that the benefit estimates are based on information concerning the preference mappings of individuals as revealed through referenda voting 2 the estireceived for publication march 9 1983 revision accepted for publication june 4 1984 state university of new york albany this paper was improved as a result of the advice and encouragement of kenneth wertz john akin david guilkey and james wilde as well as the helpful comments of two referees financial support for this research was in part provided by a dissertation research fellowship from the brookings institution 1 an example is the 1967 tax foundation study 2nmicro voting data are also used by rubinfeld 1977 to obtain information about citizens preferences for public school expenditures he uniquely estimates the parameters of a demand function up to an unknown multiplicative constant a micro demand function for education is uniquely estimated by bergstrom rubinfeld and shapiro 1982 using a different type of survey data while the method used here is to directly estimate preference mappings the information concerning such mappings embedded in such a demand function provides an

does human capital matter for growth in oecd countries a pooled mean group approach abstract unlike previous panel data studies using an improved dataset and pmg estimators we find a significant impact of human capital on growth the estimated long run elasticity of output to human capital is consistent with the microeconomic evidence on returns to schooling

social contacts and occupational choice social contacts help workers to find jobs but those jobs need not be in the occupations where workers are most productive hence social contacts can generate mismatch between a worker s occupational choice and his comparative productive advantage thus economies with dense social networks can exhibit apparently low labor force quality and as a result low returns to firms investment and depressed aggregate productivity we employ us and european data for the 1990 s to test the key prediction that social contacts distort workers occupational choices in a direction that reduces their apparent productivity we find that the use of social contacts helps find jobs one to two months sooner but leads to individual wage discounts of 5 to 7 and produces negative externalities on aggregate productivity

job polarization in europe the structure of employment is always changing and economists are always trying to understand those changes in the 1990s the idea of skill biased technological change sbtc was used to understand the shift in employment toward more educated workers see david h autor and lawrence f katz 1999 for a survey however in recent years it has become appar ent that a more nuanced approach is needed the idea of sbtc might lead one to predict a uni form shift in employment away from low skilled and toward high skilled occupations but studies for the united states autor katz and melissa s kearney 2006 and the united kingdom goos and manning 2007 have shown that there is growth in employment in both the high est skilled professional and managerial and lowest skilled personal services occupations with declining employment in the middle of the distribution manufacturing and routine office jobs this is what goos and manning 2007 term job polarization although see the introduc tion to goos and manning 2007 for antecedents of these ideas there are several hypotheses about the rea sons for job polarization first the routiniza tion hypothesis first put forward by autor frank levy and richard murnane 2003 sug gests that the effect of technological progress is to replace routine labor which tends to be clerical and craft jobs in the middle of the wage distribution second there is the view that globalization in general and offshoring in par ticular is an important source of change in the job structure in the richest countries see for example alan s blinder 2007 third there may be a link between job polarization and

the welfare cost of free public schools the welfare cost of free public schools is the difference between the cost of those schools and the maximum parents would be willing to pay to send their children to those schools estimates based on data from california school districts in 1970 indicate that this welfare cost is substantial mostly because private schools are cheaper per unit of quality than public schools

job information networks neighborhood effects and inequality this paper explores the theoretical and empirical literature to examine the use by different social groups of informal sources of information provided by friends relatives and acquaintances during job search and its consequences for the job market it also addresses the role of network structure and size the resource endowments of contacts and nature of the links between contacts to explain differences in the effects of job information networks in doing so the paper also turns to the sociology literature on job information networks and provides an economic perspective on such sociological concepts as strong versus weak ties inbreeding distance from structural holes etc the paper distinguishes between models of exogenous job information networks that is where individuals obtain job related information through a given social structure and endogenous job information networks which are social networks that result from individuals uncoordinated actions the paper pays special attention to such issues as physical and social proximity and sharing of information and discusses them in the context of the recent social interactions and neighborhood effects literature finally the paper outlines a model that integrates job information networks where interactions occur in business cycle frequencies with the dynamics of human capital formation which include the joint effects of parental community and neighborhood human capital and are set in life cycle frequencies for the purpose of organizing suggestions for future research and examining earned income inequality

a capitalization approach to fiscal incidence at the local level this paper argues that an analysis of the capitalized burdens and benefits of the local public sector offers a simple straightforward and objective computational methodology to fiscal incidence at the local level this capitalization approach represents a major departure from the highly discretionary and imprecise computational environment of the reasonable assumptions and aaron and mcguire approaches it is initially discussed both from conceptual and operational points of view and then implemented using alternate procedures major limitations of the approach are then noted a comparative perspective on fiscal incidence results based on the capitalization approach and of earlier studies on this subject is provided in the concluding section of the paper during the past two decades several important studies have been published which investigate the redistributive implications of federal provincial and local government finances in canada all the canadian studies on the subject in general follow the methodology used for similar studies in the united states these studies differ as to the shifting of tax burden assumptions and the concept of income employed and understandably their results also vary accordingly a common criticism of these approaches is that their distribution conclusions depend crucially on what incidence hypothesis is chosen musgrave and musgrave 1976 394 all these studies merely illustrate what the distribution of fiscal incidence would be if the incidence assumptions were true the numerical es

do friends and relatives really help in getting a good job informal contacts are extensively used by both firms and workers to find jobs and fill vacancies the common wisdom in the economic literature is that jobs created through this channel are of better quality and pay higher wages than jobs created through formal methods this paper explores the empirical evidence for european countries using the european community household panel echp and discovers a large cross country as well as cross industry variation in the wage differentials between jobs found through informal and formal methods across countries and industries wage premiums and wage penalties to finding jobs through personal contacts are equally frequent this paper argues that such variation can be explained by looking at firms recruitment strategies in labour markets where employers invest largely in formal recruitment activities matches created through this channel are likely to be of average better quality than those created through informal networks a simple theoretical model is used to show that employers invest more in recruitment for high productivity jobs and for positions that require considerable training the empirical predictions of the theory are successfully tested using industry level data on recruitment costs

the environmental kuznets curve semi parametrically revisited this paper re examines the existence of an environmental kuznets curve ekc across countries using a semi parametric regression estimator which places no restrictions on the functional form our results using cross country panel data on sulfur and carbon dioxide strongly suggest that the relationship between wealth and environmental degradation is not bell shaped as suggested by an ekc rather that there is a positive link for the very poorest countries and no clear relationship for richer countries

a new approach to business fluctuations heterogeneous interacting agents scaling laws and financial fragility abstract in this paper we discuss a scaling approach to business fluctuations our starting point consists in recognizing that concepts and methods derived from physics have allowed economists to re discover a set of stylized facts which have to be satisfactorily accounted for in their models standard macroeconomics based on a reductionist approach centered on the representative agent is definitely badly equipped for this task on the contrary we show that a simple financial fragility agent based model based on complex interactions of heterogeneous agents is able to replicate a large number of scaling type stylized facts with a remarkable high degree of statistical precision

international equity and differentiation in global warming policy ne of the major obstacles to reaching a comprehensive agreement on global warming is the setting of greenhouse gas emission reduction targets for individual countries long standing tensions between industrialized and developing countries have raised the issue of equity in burden sharing moreover individual industrialized nations have pleaded special circumstances and have sought differentiation in their obligations this paper analyzes alternative rules for distributing tradable carbon dioxide emissions permits a non linear programming model which distinguishes between allocation based and outcome based rules is used to analyze the relative welfare outcomes the model is applied to the world body of nations and yields several important policy implications

networks in labor markets wage and employment dynamics and inequality we present a model of labor markets that accounts for the social network through which agents hear about jobs we show that both wages and employment are positively associated a strong form of correlation across time and agents we also analyze the decisions of agents regarding staying in the labor market or dropping out if there are costs to staying in the labor market then networks of agents that start with a worse wage status will have higher drop out rates and there will be a persistent differences in wages between groups according to the starting states of their networks

constraining equitable allocations of tradable co2 emission quotas by acceptability since the signing of the kyoto protocol future commitments are likely to be framed in terms of tradable quotas the discussions on the allocation of the quotas among countries will be based at least partly on rules corresponding to a certain conception of equity for instance allocating quotas in direct proportion to population in relation to gdp or according to past emissions has been advocated taking a long term perspective we compute such allocations of tradable quotas with a dynamic closed loop model the total amount of quotas to be distributed at each period corresponds to the world optimal amount of emissions to be realized at each period we observe that most equitable allocation rules do not make the agreement individually rational for every country along the entire time path we then propose a mechanism which determines allocations of quotas that are as close as possible to any equitable allocation while satisfying individual rationality

the effects of social networks on employment and inequality we develop a model where agents obtain information about job opportunities through an explicitly modeled network of social contacts we show that employment is positively correlated across time and agents moreover unemployment exhibits duration dependence the probability of obtaining a job decreases in the length of time that an agent has been unemployed finally we examine inequality between two groups if staying in the labor market is costly and one group starts with a worse employment status then that group s drop out rate will be higher and their employment prospects will be persistently below that of the other group

justifying social discounting the rank discounted utilitarian approach the popular discounted utilitarian criterion for infinite horizon social choice has been criticized on the ground that it treats successive generations unfairly i propose to evaluate intergenerational welfare with a rank discounted utilitarian rdu criterion instead the criterion amounts to discounted utilitarianism on non decreasing paths but it treats all generations impartially discounting becomes the mere expression of intergenerational inequality aversion i show that more inequality averse rdu societies have higher social discount rates when future generations are better off i apply the rdu approach in two benchmark economic growth models and i prove that it promotes sustainable policies maximizing discounted utility

how do social networks contribute to wage inequality insights from an agent based analysis based on a closed agent based macroeconomic simulation model eurace unibi this article analyzes whether the density of social networks influences via referrals the residual wage inequality in different skill groups it is shown that an increase in network density leads to a polarization of firms and a concentration of workers with high specific skills at firms with high productivities and wages thereby enlarging within group wage inequality but not between group wage inequality

old boy networks as screening mechanisms this paper studies a fulfilled expectations equilibrium in situations in which intermediaries provide personal opinions on the likelihood of success of personnel projects or investments each referee must recommend some candidates from a group of people about whom he has private information the employer uses the recommendations to choose the workers using his expectations about the quality of the recommended and the nonrecommended applicants although the referees use their information strategically the competition among them produces optimal use of the information in the sense that employers make the same choices in equilibrium as they would if they had the same information as the referees

schumpeter meeting keynes a policy friendly model of endogenous growth and business cycles this paper studies an agent based model that bridges keynesian theories of demandgeneration and schumpeterian theories of technology fueled economic growth we employ the model to investigate the properties of macroeconomic dynamics and the impact of public polices on supply demand and the fundamentals of the economy we find profound complementarities between factors influencing aggregate demand and drivers of technological change that affect both short run fluctuations and longterm growth patterns from a normative point of view simulations show a corresponding complementarity between keynesian and schumpeterian policies in sustaining long run growth paths characterized by milder fluctuations and relatively lower unemployment levels the matching or mismatching between innovative exploration of new technologies and the conditions of demand generation appear to suggest the presence of two distinct regimes of growth or absence thereof characterized by different short run fluctuations and unemployment levels

technological acceleration skill transferability and the rise in residual inequality this paper provides a quantitative theory for the recent rise in residual wage inequality consistent with the empirical observation that a sizable part of this increase has a transitory nature a feature that eludes standard models based on ex ante heterogeneity in ability an acceleration in the rate of quality improvement of equipment like the one observed from the early 1970s increases the productivity quality differentials across machines jobs in a frictional labor market this force translates into higher wage dispersion even among ex ante equal workers with vintage human capital the acceleration reduces workers capacity to transfer skills from old to new machines generating a rise in the cross sectional variance of skills and therefore of wages through calibration the paper shows that this mechanism can account for 30 percent of the surge in residual inequality in the u s economy or for most of its transitory component two key implications of the theory faster within job wage growth and larger wage losses upon displacement find empirical support in the data

estimation of complete demand systems from household budget data the linear and quadratic expenditure systems in this paper we explore two issues in empirical demand analysis the estimation of complete systems of demand equations using household budget data section i and the incorporation of demographic characteristics into such systems section ii although there are numerous studies which use time series data to estimate complete demand systems and many which estimate engel curves from household budget data there are virtually none which combine budget data from different periods to estimate complete systems since each budget study corresponds to a single price situation one might conjecture that estimation of complete systems would not be possible unless budget studies were available from a large number of periods this is incorrect in section i we argue that interesting complete demand systems can be estimated from a small number of budget studies despite the limited price variability represented in such data to demonstrate this we use budget study data for two periods to estimate a pair of related demand systems the familiar linear expenditure system les and a quadratic expenditure system qes a generalization of les in which the demand equations are quadratic in total expenditure the inclusion of demographic variables in the analysis of household consumption patterns is desirable because there are likely to be systematic differences in the consumption behavior of households with different demographic characteristics but the effects of demographic characteristics have seldom been studied within the framework of complete demand systems in section ii we propose translating as a general method for incorporating demographic variables into complete systems of demand equations this method has not previously been discussed as a general technique for bringing demographic variables into demand systems although it has been employed in several studies to improve the estimates of the les and the qes presented in section i we reestimate these two systems using translating to incorporate family size

some contacts are more equal than others informal networks job tenure and wages the explanation typically given for longer tenure among workers who use informal contacts to find jobs is that relatives and friends reduce uncertainty about the quality of the match between worker and employer an alternative explanation is that workers rely on informal information sources as a last resort such workers remain at their current jobs mainly because they have few alternative choices rather than because of better match quality this article shows that the two different explanations are simultaneously valid for different types of contacts and can account for differences in the wage effects of job contacts

an examination of preferences for local public sector outputs relatively unique data on the costs of public services for local governments in victoria australia are used to estimate a system of demand equations and to test alternative specifications of the underlying preferences using a translog model symmetry conditions are rejected so the data are not consistent with constrained utility maximization a nonparametric test confirms that result conditional on symmetry tests reject homogeneity and the additivity of preferences and also the separability of personal and property services copyright 1988 by mit press

matchmaker matchmaker the effect of old boy networks on job match quality earnings and tenure firms often view job applicant referrals from current employees as more informative than direct applications or referrals through formal labor market intermediaries such as placement firms we argue that old boy networks reduce employers uncertainty about worker productivity using jovanovic s job matching model we show that workers hired through the old boy network should 1 earn higher initial salaries 2 experience lower subsequent wage growth on the job and 3 stay on the job longer than otherwise comparable workers hired from outside the network we find considerable support for this theory using data from the 1972 survey of natural and social scientists and engineers
