any non welfarist method of policy assessment violates the pareto principle reply the public at large many policymakers and a number of economists hold views of social welfare that are non welfarist that is they attach some importance to factors other than the effects of policies on individuals utilities we show however that any non welfarist method of policy assessment violates the pareto principle

information school choice and academic achievement evidence from two experiments we examine a natural experiment and a field experiment that provided direct information on school test scores to lower income families in a public school choice plan receiving information significantly increases the fraction of parents choosing higher performing schools parents with high scoring alternatives nearby were more likely to choose nonguaranteed schools with higher test scores using random variation from each experiment we find that attending a higher scoring school increases student test scores the results imply that school choice will most effectively increase academic achievement for disadvantaged students when parents have easy access to test score information and good options from which to choose

intergenerational income group mobility and differential fertility one question development economists are especially interested in but so far left unanswered is how would the societal income distribution be affected by introducing a family planning program to reduce the reproduction rate of the poor which is usually high in developing countries the purpose of this paper is to search for analytical answers to this question we are able to make definite comparisons about some class of inequality measures of the steady state societal income distributions and these comparisons provide strong theoretical support in favor of the above mentioned family planning program excerpt

fertility social mobility and long run inequality dynastic altruistic models with endogenous fertility have been shown to be unable to generate enough intergenerational persistence using a bewley model with endogenous fertility we show that it is possible to recover persistence key ingredients for our result include exponential child discounting discrete number of children diminishing costs of child rearing and an elasticity of intergenerational substitution larger than one our model provides a unified framework of analysis for long run inequality that incorporates fertility choices

wealth distribution in life cycle economies abstract this paper compares the age wealth distribution produced in life cycle economies to the corresponding distribution in the us economy the idea is to calibrate the model economies to match features of the us earnings distribution and then examine the wealth distribution implications of the model economies the findings are that the calibrated model economies with earnings and lifetime uncertainty can replicate measures of both aggregate wealth and transfer wealth in the us furthermore the model economies produce the us wealth gini and a significant fraction of the wealth inequality within age groups however the model economies produce less than half the fraction of wealth held by the top 1 percent of us households

optimal contracting with dynastic altruism family size and per capita consumption we use a barro becker model of endogenous fertility in which parents are subject to idiosyncratic shocks that are private information either to labor productivity or taste for leisure to study the efficient degree of consumption inequality in the long run the planner uses the trade off between family size and future consumption and leisure to provide incentives for workers to reveal their shocks we show that in this environment the optimal dynamic contract no longer features immiseration in consumption we also discuss the implications of the model on the long run properties of family size in the optimal contract and show that the long run trend in dynasty size can be either positive or negative depending on parameters

trends in intergenerational income mobility previous studies of recent u s trends in intergenerational income mobility have produced widely varying results partly because of large sampling errors by making more efficient use of the available information in the panel study of income dynamics we generate more reliable estimates of the recent time series variation in intergenerational mobility our results which pertain to the cohorts born between 1952 and 1975 do not reveal major changes in intergenerational mobility

transitional dynamics and the distribution of wealth in a neoclassical growth model abstract the evolution of the personal distribution of wealth in a standard neoclassical growth model is studied if the economy is growing toward the steady state and preferences are such that marginal utility from consumption is infinite finite at some all positive non negative consumption level s then the average saving propensity of agents is positively negatively related to their wealth if the economy is decaying toward the steady state these relationships are reversed if wealth and average saving propensity are positively negatively related the distribution of current period wealth lorenz dominates is lorenz dominated by next period s distribution of wealth

the effect of school choice on participants evidence from randomized lotteries school choice has become an increasingly prominent strategy for enhancing academic achievement to evaluate the impact on participants we exploit randomized lotteries that determine high school admission in the chicago public schools compared to those students who lose lotteries students who win attend high schools that are better in a number of dimensions including peer achievement and attainment levels nonetheless we find little evidence that winning a lottery provides any systematic benefit across a wide variety of traditional academic measures lottery winners do however experience improvements on a subset of nontraditional outcome measures such as self reported disciplinary incidents and arrest rates

intergenerational transfers and the fertility income relationship evidence from cross sectional data reveals a negative relationship between family income and fertility this article argues that constraints to intergenerational transfers are crucial for understanding this relationship if parents could legally impose debt obligations on their children to recover the costs incurred in raising them then fertility would be independent of parental income a relationship between fertility and income arises when parents are unable to leave debts because of legal enforcement or moral constraints this relationship is negative when the intergenerational elasticity of substitution is larger than one a case in which parental consumption is a good substitute for children s consumption

do family wealth shocks affect fertility choices evidence from the housing market abstract this paper uses wealth changes driven by housing market variation to estimate the effect of family resources on fertility decisions using data from the panel study of income dynamics we show that a 100 000 increase in housing wealth among home owners causes a 16 to 18 increase in the probability of having a child there is no evidence of an effect of msa level housing price growth on the fertility of renters however we also present evidence that housing wealth growth increases total fertility and that the responsiveness of fertility to housing wealth has increased over time commensurate with the recent housing boom

random earnings differences lifetime liquidity constraints and altruistic intergenerational transfers abstract this paper develops a model of private savings behavior in which households care about their descendants cannot have negative net worth and have lifetime earnings depending on random draws from an exogenous distribution of abilities the elements interact very lucky parents are likely to leave large estates constrained children are unusually likely to receive intergenerational transfers the paper proves the existence of a stationary cross sectional distribution of wealth endogenously determines where liquidity constraints will bind and shows that the long term interest rate must be such that ricardian neutrality fails its last section generates several illustrative numerical simulations

accounting for the u s earnings and wealth inequality we show that a theory of earnings and wealth inequality based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units accounts for the u s earnings and wealth inequality almost exactly

why does the law of one price fail an experiment on index mutual funds we conduct an experiment to evaluate why individuals invest in high fee index funds in our experiments subjects allocate 10 000 across four s p 500 index funds and are rewarded for their portfolio s subsequent return subjects overwhelmingly fail to minimize fees we can reject the hypothesis that subjects buy high fee index funds because of bundled non portfolio services search costs for fees matter but even when we eliminate these costs fees are not minimized instead subjects place high weight on annualized returns since inception fees paid decrease with financial literacy interestingly subjects who choose high fee funds sense they are making a mistake

private school vouchers and student achievement an evaluation of the milwaukee parental choice program in 1990 wisconsin began providing vouchers to a small number of low income students to attend nonsectarian private schools controlling for individual fixed effects i compare the test scores of students selected to attend a participating private school with those of unsuccessful applicants and other students from the milwaukee public schools i find that students in the milwaukee parental choice program had faster math score gains than but similar reading score gains to the comparison groups the results appear robust to data imputations and sample attrition although these deficiencies of the data should be kept in mind when interpreting the results

parental altruism and the value of avoiding acute illness are kids worth more than parents abstract a model describing parents preferences to relieve their own and their children s acute illnesses is estimated using stated preference data estimated marginal rates of substitution mrs between child and parent illness are about two indicating that parents value children s illness attributes twice as highly as their own the mrs is larger for younger children falls toward unity as the child approaches adulthood and appears to reflect parental altruism rather than parent child differences in initial health or illness costs intra family allocations may compensate for chronic health impairments parents willingness to pay to avoid own or child illness increases with income declines with fertility increases at a decreasing rate with duration and number of symptoms and depends on perceived discomfort and activity restrictions current methods of assessing morbidity benefits of environmental regulations may understate substantially the value of children s health particularly in african american families

intergenerational persistence of earnings the role of early and college education recent empirical evidence from the united states indicates a high degree of persistence in earnings across generations designing effective public policies to increase social mobility requires identifying and measuring the major sources of persistence and inequality in earnings we provide a quantitative model of intergenerational human capital transmission that focuses on three sources innate ability early education and college education we find that approximately one half of the intergenerational correlation in earnings is accounted for by parental investment in education in particular early education we show that these results have important implications for education policy

income and wealth heterogeneity in the macroeconomy how do movements in the distribution of income and wealth affect the macroeconomy we analyze this question using a calibrated version of the stochastic growth model with partially uninsurable idiosyncratic risk and movements in aggregate productivity our main finding is that in the stationary stochastic equilibrium the behavior of the macroeconomic aggregates can be almost perfectly described using only the mean of the wealth distribution this result is robust to substantial changes in both parameter values and model specification our benchmark model whose only difference from the representative agent framework is the existence of uninsurable idiosyncratic risk displays far less cross sectional dispersion and skewness in wealth than u s data however an extension that relies on a small amount of heterogeneity in thrift does succeed in replicating the key features of the wealth data furthermore this extension features aggregate time series that depart significantly from permanent income behavior

bequests as signals an explanation for the equal division puzzle in the united states more than two thirds of decedents with multichild families divide their estates exactly equally among their children in contrast gifts given before death are usually unequal these findings challenge the validity of existing theories regarding the determination of intergenerational transfers in this paper we develop a theory that accounts for this puzzle based on the notion that the division of bequests provides a signal about a parent s altruistic preferences the theory can also explain the norm of unigeniture which prevails in other societies

retirement wealth and lifetime earnings this article argues that a satisfactory theory of wealth inequality should account not only for the marginal distribution of wealth but also for the joint distribution of wealth and earnings the article describes the joint distribution of retirement wealth and lifetime earnings in the panel study of income dynamics it then evaluates the ability of a stochastic life cycle model to account for key features of this distribution the life cycle model fails to account for three key features of the data 1 the correlation between lifetime earnings and retirement wealth is too high 2 the wealth gaps between earnings rich and earnings poor households are too large 3 wealth inequality among households with similar lifetime earnings is too small models in which households differ in rates of return or time preferences account much better for the joint distribution of retirement wealth and lifetime earnings

long term educational consequences of secondary school vouchers evidence from administrative records in colombia colombia s paces program provided over 125 000 poor children with vouchers that covered the cost of private secondary school the vouchers were renewable annually conditional on adequate academic progress since many vouchers were assigned by lottery program effects can reliably be assessed by comparing lottery winners and losers estimates using administrative records suggest the paces program increases secondary school completion rates by 15 to 20 percent correcting for the greater percentage of lottery winners taking college admissions tests the program increased test scores by two tenths of a standard deviation in the distribution of potential test scores jel i21 j12 i28

free markets and fettered consumers are consumers sufficiently self interested and self reliant so that privatized markets deliver the efficiency and welfare gains they promise why are consumers uncomfortable in markets and in some case sufficiently opposed to market solutions to prevent their implementation what can be done to prepare consumers so that they function satisfactorily in markets and understand the advantages of market based resource allocation this paper examines the foundations of consumer behavior and attitudes in markets and proposes a program of scientific research to determine how consumers cope in privatized markets and the implications for market design of the limits of self reliance

the elasticity of intergenerational substitution parental altruism and fertility choice dynastic models common in macroeconomics use a single parameter to control the willingness of individuals to substitute consumption both intertemporally or across periods and intergenerationally or across parents and their children this article defines the concept of elasticity of intergenerational substitution egs and extends a standard dynastic model in order to disentangle the egs from the eis or elasticity of intertemporal substitution a calibrated version of the model lends strong support to the notion that the egs is significantly larger than one in contrast estimates of the eis suggests that it is at most one what disciplines the identification is the need to match empirically plausible fertility rates for the u s we illustrate the potential role of the egs in macroeconomics

the dynamics of population growth differential fertility and inequality studies of population growth relative to income distribution from single equation and simultaneous equation models have shown that higher population growth rates increase inequality the reasons for this inequality contain important welfare issues including the fact that different income groups grow at different rates with lower income the fastest the differential fertility of the income groups complicates these issues the lorenz curve has often been used as a foundation of the theory of inequality comparisons and uses cumulative shares of income as a function of cumulative shares of population the mortality rates age of new entrants and the mobility across income groups must be factored in these can be analyzed simultaneously using a multistate life table which describes simultaneous transitions across age groups and states data from brazil was used to test whether increase in the fertility rates of the poor would affect income inequality the results indicate a 100 increase in the fertility of the poor which increases the percentage of poor in the equal fertility case there were decreases in the percent of poor from the original number these results confirm that inequality measures can give conflicting signals and could be inconsistent with real changes in relative welfare analyzing relationships between population growth and inequality is difficult and standard measures are inadequate to test hypotheses about the distribution effects of migration or high fertility it appears to be impossible to differentiate changes in population make up from changes in economic status

what do parents value in education an empirical investigation of parents revealed preferences for teachers this paper examines revealed preferences of parents for their children s education using parent requests for individual elementary school teachers and information on teacher attributes including principal reports of teacher characteristics that are typically unobservable on average parents strongly prefer teachers whom principals describe as good at promoting student satisfaction though they also value teacher ability to raise academic achievement these aggregate effects mask striking differences across schools families in higher poverty schools strongly value student achievement and appear indifferent to the principal s report of a teacher s ability to promote student satisfaction the results are reversed for families in wealthier schools

the failure of competition in the credit card market the bank credit card market containing 4 000 firms and lacking regulatory barriers casually appears to be a hospitable environment for the model of perfect competition nevertheless this article reports that credit card interest rates have been exceptionally sticky relative to the cost of funds moreover major credit card issuers have persistently earned from three to five times the ordinary rate of return in banking during the periods 1983 88 the failure of the competitive model appears to be partly attributable to consumers making credit card choices without taking account of the very high probability that they will pay interest on their outstanding balances copyright 1991 by american economic association

inequality and growth why differential fertility matters we argue that inequality and growth are linked through differential fertility and the accumulation of human capital we build an overlapping generations model in which dynasties differ in their initial endowment with human capital growth the income distribution and fertility are endogenous due to a quantiy quality tradeoff families with less human capital decide to have more children and invest less in education when initial inequality is high large fertility differentials lower the growth rate of average human capital since poor families who invest little in education make up a large fraction of the population in the next generation a calibrated model shows that this fertility differential effect is quantitatively important we also provide empirical evidence to confirm the links between inequality differential fertility and growth suggested by the model

do accountability and voucher threats improve low performing schools abstract we study the effects of the threat of vouchers and stigma in florida on the performance of low performing schools estimates of the change in raw test scores from the first year of the reform are consistent with the early results which claimed large improvements associated with the threat of vouchers however we also find that much of this estimated effect may be due to other factors the relative gains in reading are largely explained by changing student characteristics and the gains in math though larger appear limited to the high stakes grade we also find some evidence that these improvements were due more to the stigma of receiving the low grade rather than the threat of vouchers

feasible methods to estimate disease based price indexes abstract there is a consensus that statistical agencies should report medical data by disease rather than by service this study computes price indexes that are necessary to deflate nominal disease expenditures and to decompose their growth into price treated prevalence and output per patient growth unlike previous studies it uses methods that can be implemented by the bureau of labor statistics bls for the calendar years 2005 2010 i find that these feasible disease based indexes are approximately 1 lower on an annual basis than indexes computed by current methods at bls this gives evidence that traditional medical price indexes have not accounted for the more efficient use of medical inputs in treating most diseases
