the effect of income on child development this study presents estimates of the effect of parental income on children s cognitive social and emotional development the effect of current income is small especially when income is treated as endogenous the effect of permanent income is substantially larger but relatively small when compared to the magnitude of recent policy induced changes in income family background characteristics play a more important role than income in determining child outcomes policies that affect family income will have little direct impact on child development unless they result in very large and permanent changes in income

integrating the human sciences to evolve effective policies this paper describes an evolutionary perspective on human development and wellbeing and contrasts it with the model of self interest that is prominent in economics the two approaches have considerably different implications for how human wellbeing might be improved research in psychology prevention science and neuroscience is converging on an evolutionary account of the importance of two contrasting suites of social behavior prosociality vs antisocial behaviors crime drug abuse risky sexual behavior and related problems such as depression prosociality of individuals and groups evolves in environments that minimize toxic biological and social conditions promote and richly reinforce prosocial behavior and attitudes limit opportunities for antisocial behavior and nurture the pursuit of prosocial values conversely antisocial behavior and related problems emerge in environments that are high in threat and conflict over the past 30 years randomized trials have shown numerous family school and community interventions to prevent most problem behaviors and promote prosociality research has also shown that poverty and economic inequality are major risk factors for the development of problem behaviors the paper describes policies that can reduce poverty and benefit youth development although it is clear that the canonical economic model of rational self interest has made a significant contribution to the science of economics the evidence reviewed here shows that it must be reconciled with an evolutionary perspective on human development and wellbeing if society is going to evolve public policies that advance the health and wellbeing of the entire population

out of the wallet and into the purse using micro data to test income pooling this paper uses an exogenous change in the intrahousehold distribution of income provided by a change in united kingdom family allowance policy to test the income pooling hypothesis implied by unitary household models expenditure shares are estimated for a wide range of goods using household level data shifts in expenditure shares suggest that children and mothers benefited at the expense of fathers when this policy change shifted income within households from men to women similar shifts are not found among married couple households with no children this paper refutes income pooling and confirms and extends results in lundberg pollak and wales 1997

teacher quality in educational production tracking decay and student achievement growing concerns over the inadequate achievement of u s students have led to proposals to reward good teachers and penalize or fire bad ones the leading method for assessing teacher quality is value added modeling vam which decomposes students test scores into components attributed to student heterogeneity and to teacher quality implicit in the vam approach are strong assumptions about the nature of the educational production function and the assignment of students to classrooms in this paper i develop falsification tests for three widely used vam specifications based on the idea that future teachers cannot influence students past achievement in da ta from north carolina each of the vams exclusion restrictions are dramatically viola ted in particular these models indicate large effects of 5th grade teachers on 4th grade t est score gains i also find that conventional measures of individual teachers value added fade out very quickly and are at best weakly related to long run effects i discuss implic ations for the use of vams as personnel tools

correlations of brothers earnings and intergenerational transmission correlations between parent and child earnings reflect intergenerational mobility and more broadly correlations between siblings earnings reflect shared community and family background these earnings relationships capture important aspects of relations in socioeconomic status more generally we estimate intergenerational transmission and sibling correlations of life cycle earnings jointly within a unified framework that nests previous models using data on the danish population of father first son second son triads we find that intergenerational effects account for on average 72 percent of sibling correlations this share is higher than all previous studies because we allow for heterogeneous intergenerational transmission between families sibling correlations exhibit a u shape over the working life consistent with differences in human capital investments between families

permanent and transitory movements in labor income an explanation for excess smoothness in consumption many have argued that if labor income is difference stationary the permanent income hypothesis predicts that consumption should be relatively volatile in u s aggregate data labor income is well characterized as having a unit root however consumption turns out to be relatively smooth this anomaly is known as deaton s paradox i resolve deaton s paradox by providing decompositions of labor income into permanent and transitory components these preserve the univariate dynamic properties of labor income however when agents distinguish permanent and transitory movements in their labor income as the rational expectations hypothesis asserts they should the permanent income hypothesis correctly predicts the observed smoothness in consumption

testing for indeterminacy an application to u s monetary policy reply this paper considers a prototypical new keynesian model in which the equilibrium is undetermined if monetary policy is passive the likelihood based estimation of dynamic equilibrium models is extended to allow for indeterminacies and sunspot fluctuations we construct posterior weights for the determinacy and indeterminacy region of the parameter space and estimates for the propagation of fundamental and sunspot shocks according to the estimated model u s monetary policy post 1982 is consistent with determinacy whereas the pre volcker policy is not we find that before 1979 indeterminacy substantially altered the propagation of shocks

current real business cycle theories and aggregate labor market fluctuations hours worked and the return to working are weakly correlated traditionally the ability to account for this fact has been a litmus test for macroeconomic models existing real business cycle models fail this test dramatically we modify prototypical real business cycle models by allowing government consumption shocks to influence labor market dynamics this modification can in principle bring the models into closer conformity with the data our empirical results indicate that it does

the intergenerational effects of compulsory schooling this article attempts to improve our understanding of the causal processes that contribute to intergenerational immobility by exploiting historical changes in compulsory schooling laws that affected the educational attainment of parents without affecting their innate abilities or endowments we examine the influence of parental compulsory schooling on children s grade for age using the 1960 1970 and 1980 u s censuses our estimates indicate that a 1 year increase in the education of either parent reduces the probability that a child repeats a grade by between 2 and 4 percentage points

shocking behavior random wealth in antebellum georgia and human capital across generations does the lack of wealth constrain parents investments in the human capital of their descendants we conduct a nearly fifty year followup of an episode in which such constraints would have been plausibly relaxed by a random allocation of substantial wealth to families we track descendants of participants in georgia s cherokee land lottery of 1832 in which nearly every adult white male in georgia took part winners received close to the median level of wealth a large financial windfall orthogonal to participants underlying characteristics that might have also affected their children s human capital although winners had slightly more children than non winners they did not send them to school more sons of winners have no better adult outcomes wealth income literacy than the sons of non winners and winners grandchildren do not have higher literacy or school attendance than non winners grandchildren this suggests only a limited role for family financial resources in the formation of human capital in the next generations in this environment and a potentially more important role for other factors that persist through family lines

estimating labour supply responses using tax reforms the 1980 s tax reforms and the changing dispersion of wages offer one of the best opportunities yet to estimate labor supply effects nevertheless changing sample composition aggregate shocks the changing composition of the tax paying population and discontinuities in the tax system create serious identification and estimation problems we develop grouping estimators that address these issues our results reveal positive and moderately sized wage elasticities we also find negative income effects for women with children

external effects in u s procyclical productivity abstract in this paper we highlight a new dimension of the aggregate procyclical productivity phenomenon we show that estimates of the degree of returns to scale are larger for manufacturing as a whole than for two digit industries since this difference must be due to factors that are only internalized at the most aggregate level we term it an external effect this result rules out explanations based on own input variation such as true increasing returns and unmeasured factor utilization tied to own activity as the sole explanations for aggregate procyclical productivity we explore several potential explanations of this external effect

do husbands and wives pool their resources evidence from the united kingdom child benefit common preference models of family behavior imply income pooling a restriction on family demand functions such that only the sum of husband s income and wife s income affects the allocation of goods and time testing the pooling hypothesis is difficult because most family income sources are not exogenous to the allocations being analyzed in this paper we present an alternative test based on a natural experiment a policy change in the united kingdom that transferred a substantial child allowance to wives in the late 1970s using family expenditure survey data we find strong evidence that a shift toward greater expenditures on women s clothing and children s clothing relative to men s clothing coincided with this income redistribution

real business cycles and sunspot fluctuations are observationally equivalent abstract this paper points out that real business cycle models are observationally equivalent to externality models which we define as models with externalities and sunspots but without productivity shocks as far as standard first order systems are concerned however externality models turn out to be more flexible than rbc models this explains at least partly why previous studies have found that externality models perform better than standard rbc models at generating realistic business cycle behavior our results cast doubt on the arguments of farmer and guo 1994 and caballero and lyons 1992

children s schooling and parents behavior evidence from the head start impact study abstract parents may have important effects on their children but little work in economics explores whether children s schooling opportunities crowd out or encourage parents investment in children we analyze data from the head start impact study which granted randomly chosen preschool aged children the opportunity to attend head start we find that head start causes a substantial increase in parents involvement with their children such as time spent reading to children math activities or days spent with children by fathers who do not live with their children both during and after the period when their children are potentially enrolled in head start

indivisible labor lotteries and equilibrium abstract this paper considers an economy where labor is indivisible and agents are identical although the discontinuity in labor supply at the individual level disappears as a result of aggregation it is shown that indivisible labor has strong consequences for the aggregate bahavior of the economy it is also shown that optimal allocations involve lotteries over employment and consumption

indivisible labor and the business cycle abstract a growth model with shocks to technology is studied labor is indivisible so all variability in hours worked is due to fluctuations in the number employed we find that unlike previous equilibrium models of the business cycle this economy displays large fluctuations in hours worked and relatively small fluctuations in productivity this finding is independent of individuals willingness to substitute leisure across time this and other findings are the result of studying and comparing summary statistics describing this economy an economy with divisible labor and post war u s time series

indeterminacy and increasing returns abstract we investigate properties of the one sector growth model with increasing returns under two organizational structures capable of reconciling the existence of aggregate increasing returns with competitive behavior by firms the first involves input externalities the second involves monopolistic competition we show for parameters in close accord with recent literature on real business cycles that the model displays an indeterminate steady state that can be exploited to generate a model of business fluctuations driven by self fulfilling beliefs in our first class of models growth is generated by exogenous increases in factor productivity in the second class the marginal product of capital is large enough for endogenous growth journal of economic literature classification numbers e00 e3 o40

economic influences on the structure of local government in u s metropolitan areas abstract there is a large degree of variation in the number of general purpose local governments and school districts per square mile and per person among united states metropolitan areas using data from 1982 this paper provides an empirical test of whether economic factors especially variation in demand for local government services partly account for these differences the empirical findings show that after controlling for political historic and institutional factors variations in the characteristics that affect demand for local government services do influence the number of local governments this result is consistent with the hypothesis first put forth by tiebout

why the apple doesn t fall far understanding intergenerational transmission of human capital parents with higher education levels have children with higher education levels however is this because parental education actually changes the outcomes of children suggesting an important spillover of education policies or is it merely that more able individuals who have higher education also have more able children this paper proposes to answer this question with a unique dataset from norway using the reform of the education system that was implemented in different municipalities at different times in the 1960s as an instrument for parental education we find little evidence of a causal relationship between parents education and children s education despite significant ols relationships we find 2sls estimates that are consistently lower than the ols estimates with the only statistically significant effect being a positive relationship between mother s education and son s education these findings suggest that the high correlations between parents and children s education are due primarily to family characteristics and inherited ability and not education spillovers

oil vulnerability in the australian city assessing socioeconomic risks from higher urban fuel prices global oil prices have risen markedly over the past 18 months generating considerable speculation regarding their economic and social impacts cities that are highly dependent on petroleum for urban transport are likely to be most adversely affected by rising oil prices yet there has been little recent scholarly engagement with the socioeconomic implications of increasing oil prices this paper develops a basic framework and methodology for assessing the socioeconomic oil vulnerability of australian cities the paper demonstrates that there is wide spatial variability in the vulnerability of australia s urban populations to rising fuel costs which may compound existing socio spatial divisions and speculates on some underlying causal factors the paper calls for better data and new methods to understand the issue

accounting for the change in income disparities between us central cities and their suburbs from 1980 to 1990 in this paper we are concerned with the widely acknowledged policy problem of substantially higher levels of per capita income in suburban areas of us metropolitan areas compared to that of their central cities we focus on causes of changes in this per capita income gap from 1980 to 1990 for those metropolitan areas where such a gap existed in 1980 in an effort to determine what factors are associated with narrowing of these disparities we do so by first describing the relationship between central city and suburban per capita income across american metropolitan areas in 1980 and 1990 we review the connection between the operation of metropolitan labour markets and changes in suburban central city income disparities we then develop regression models of changes in income disparities for all 111 metropolitan statistical areas msas with populations of at least 250 000 in 1980 and where suburban per capita income exceeded central city per capita income in 1980 this is followed by a summary of the results

externalities and nonlinear discounting indeterminacy abstract this paper studies a one sector model with externalities and nonlinear discounting loosely if the bellman equation for a standard model is written as v k max u v k then the bellman equation for our model is written as v k max u b v k for some concave function b our model assumes that period utility u is linear in consumption and leisure and the production function exhibits increasing social returns and nonincreasing private returns we establish the existence of a steady state under fairly general conditions and give a necessary and sufficient condition for local indeterminacy we show that regardless of the degrees of increasing returns and externalities there exists a discount function b such that indeterminacy arises we also show that in a certain sense as the degree of increasing returns converges to zero the variability of discounting the second derivative of b required to generate indeterminacy also converges to zero numerical examples are provided the main results are also extended to a one sector model with fixed labor supply

poverty and urban public expenditures cities in the us bear a disproportionate responsibility for the public expenditures that grow out of poverty because they contain disproportionate numbers of the poor and because a substantial part

wealth health and child development evidence from administrative data on swedish lottery players we use administrative data on swedish lottery players to estimate the causal impact of substantial wealth shocks on players own health and their children s health and developmental outcomes our estimation sample is large virtually free of attrition and allows us to control for the factors conditional on which the prizes were randomly assigned in adults we find no evidence that wealth impacts mortality or health care utilization with the possible exception of a small reduction in the consumption of mental health drugs our estimates allow us to rule out effects on 10 year mortality one sixth as large as the crosssectional wealth mortality gradient in our intergenerational analyses we find that wealth increases children s health care utilization in the years following the lottery and may also reduce obesity risk the effects on most other child outcomes including drug consumption scholastic performance and skills can usually be bounded to a tight interval around zero overall our findings suggest that in affluent countries with extensive social safety nets causal effects of wealth are not a major source of the wealth mortality gradients nor of the observed relationships between child developmental outcomes and household income jel codes i10 i14 j24

the impact of housing assistance on child outcomes evidence from a randomized housing lottery one long standing motivation for low income housing programs is the possibility that housing affordability and housing conditions generate externalities including on children s behavior and long term life outcomes we take advantage of a randomized housing voucher lottery in chicago in 1997 to examine the longterm impact of housing assistance on a wide variety of child outcomes including schooling health and criminal involvement in contrast to most prior work focusing on families in public housing we focus on families living in unsubsidized private housing at baseline for whom voucher receipt generates large changes in both housing and nonhousing consumption we find that the receipt of housing assistance has little if any impact on neighborhood or school quality or on a wide

growth externalities and sunspots abstract in this paper we consider a simple model of neo classical capital accumulation with production externalities in which a continuum of identical infinitely lived agents produce output from a standard stationary neo classical production technology and choose their actions to maximize a discounted sum of single period utilities because of the presence of the externality in production the model exhibits sunspot equilibria

productivity shocks and real business cycles abstract productivity shocks play a central role in real business cycles as an exogenous impulse to macroeconomic activity however measured solow prescott residuals do not behave as an exogenous impulse rather econometric evidence provided in this paper indicates that 1 money interest rates and government spending granger cause these impulses and 2 a substantial component of the variance of these impulses between one quarter and one half is attributable to variations in aggregate demand these results are robust to a number of econometric issues including measurement errors specification of the production function and certain forms of omitted real variables

the changing spatial concentration of income and poverty among suburbs of large us metropolitan areas after developing a longitudinal data base of civil divisions within 27 large metropolitan areas msas from the 1970 1990 us censuses this study examines changes in the spatial concentration of income and poverty within these msas a series of cross sectional analyses of geographical and social determinants of poverty rates and median household income are used to analyse whether the determinants are changing over time large older central cities in the north east and mid west have experienced increasing poverty and decreases in income relative to their own history and relative to their own suburbs there is some evidence of economic decline in the inner suburbs of these central cities relative to other suburbs but not relative to the central cities the geographical shifts in msa population among suburbs by income between 1970 and 1990 are analysed relative to initial social characteristics of civil divisions the study concludes that the filtering of older residential buildings to and the lower margi

house price growth when children are teenagers a path to higher earnings abstract this paper examines whether rising house prices immediately prior to children entering college have an impact on their earnings as adults higher house prices provide homeowners with additional funding to invest in their children s human capital but also raise housing costs the results show that a 1 percentage point increase in house prices when children are 17 years old results in roughly 0 9 percent higher annual income for the children of homeowners and 1 5 percent lower annual income for the children of renters house price appreciation at age 17 also leads to higher college enrollment rates at age 19 and an increased likelihood of attendance at higher ranked post secondary institutions for children of homeowners as well as lower college enrollment rates for children of renters

transfers to households with children and child development in this paper we utilize a model of household investments in the development of children to explore the impact of various transfer policies on the distribution of child outcomes we develop a cost criterion that can be used to compare the cost effectiveness of unrestricted restricted and conditional cash transfer systems and find that an optimally chosen conditional cash transfer program is the most cost efficient way to attain any given gain in average child quality we explore several design elements for the conditional cash transfer system and discuss the role of production function uncertainty and measurement error

the intergenerational effects of worker displacement this article uses variation induced by firm closures to explore the intergenerational effects of worker displacement using a canadian panel of administrative data that follows more than 39 000 father son pairs from 1978 to 1999 we find that children whose fathers were displaced have annual earnings about 9 lower than similar children whose fathers did not experience an employment shock they are also more likely to receive unemployment insurance and social assistance the estimates are driven by the experiences of children whose family income was at the bottom of the income distribution

early and late human capital investments borrowing constraints and the family we develop a dynastic human capital investment framework to study the importance of family borrowing constraints and uninsured labor market risk as well as the process of intergenerational ability

real business cycles in this paper we demonstrate how certain very ordinary economic principles lead maximizing individuals to choose consumption production plans that display many of the characteristics commonly associated with business cycles our explanation is entirely consistent with i rational expectations ii complete current information iii stable preferences iv no technological change v no long lived commodities vi no frictions or adjustment costs vii no government viii no money and ix no serial dependence in the stochastic elements of the environment we also provide a completely worked out example of the type of artificial economy we have in mind the time series properties of the example exhibit some major features of observed business cycles although this type of model may not be capable of explaining all of the regularities in actual business cycles we believe that it provides a useful well defined benchmark for assessing the relative importance of factors e g monetary disturbances

real business cycles and the animal spirits hypothesis abstract we calibrate a quantitative equilibrium macroeconomic model with an aggregate technology that is subject to increasing returns and show that this model may display fluctuations at business cycle frequencies even when there are no shocks to the fundamentals of the economy these fluctuations are due to the self fulfilling beliefs of investors which we call animal spirits we compare the impulse response functions predicted by our model and by two other more standard models with a four variable vector autoregression on u s data our animal spirits economy is the most successful of the three at matching broad features of the dynamic responses in the data journal of economic literature classification numbers e00 e3 e32

does raising family income cause better child health evidence from china abstractfew studies have attempted to identify a causal link between family income and child health especially in developing countries this article takes advantage of an exogenous income shock created by china s rural tax reform between 2000 and 2003 to study the causal impact of household income on child health the analysis finds that an increase in family income significantly raises children s height for age z scores these effects are robust to alternative specifications and a comprehensive set of controls the article also investigates possible mechanisms generating this result we find that with a higher income level better nutritional intake partially accounts for the improvement in child health

the elasticity of taxable income evidence and implications abstract a central tax policy parameter that has recently received much attention but about which there is substantial uncertainty is the overall elasticity of taxable income we provide new estimates of this elasticity which address identification problems with previous work by exploiting a long panel of tax returns to study a series of tax reforms throughout the 1980s this identification strategy also allows us to provide new evidence on both the income effects of tax changes on taxable income and on variation in the elasticity of taxable income by income group we find that the overall elasticity of taxable income is approximately 0 4 the elasticity of real income not including tax preferences is much lower we estimate small income effects of tax changes on reported income implying that the compensated and uncompensated elasticities of taxable income are very similar we estimate that this overall elasticity is primarily due to a very elastic response of taxable income for taxpayers who have incomes above 100 000 per year who have an elasticity of 0 57 while for those with incomes below 100 000 per year the elasticity is less than one third as large moreover high income taxpayers who itemize are particularly responsive to taxation our estimates suggest that optimal tax structures may feature tightly targeted transfers to lower income taxpayers and a flat or even declining marginal rate structure for middle and high income taxpayers

the impact of family income on child achievement evidence from the earned income tax credit using an instrumental variables strategy we estimate the causal effect of income on children s math and reading achievement our identification derives from the large nonlinear changes in the earned income tax credit the largest of these changes increased family income by as much as 20 percent or approximately 2 100 between 1993 and 1997 our baseline estimates imply that a 1 000 increase in income raises combined math and reading test scores by 6 percent of a standard deviation in the short run test gains are larger for children from disadvantaged families and robust to a variety of alternative specifications jel h24 h31 i21 i38 j13
