winners and losers in housing markets this paper is a quantitatively oriented theoretical study into the interaction between housing prices aggregate production and household behaviour over a lifetime we develop a life cycle model of a production economy in which land and capital are used to build residential and commercial structures we find that in an economy where the share of land in the value of structures is large housing prices react more to an exogenous change in expected productivity or the world interest rate causing large redistribution effects between net buyers and net sellers of houses changing the financing constraint however has limited effects on housing prices

learning your earning are labor income shocks really very persistent in this paper we examine the risk situation facing individuals in the labor market the current consensus in the literature is that the labor income process has a large random walk component we argue two points first the estimates of persistence from income data appear to be upward biased due to the omission of heterogeneity in income pro les across the population that would be implied for example by a human capital model with heterogeneity when we allow for dierences in pro les the estimated persistence falls from 0 99 to about 0 8 moreover the main evidence against pro le heterogeneity in the existing literature that the autocorrelations of income changes are small and typically negative is also replicated by the pro le heterogeneity model we estimate casting doubt on the previous interpretation of this evidence second we embed this process in a life cycle model to examine how it alters individuals consumption saving decision we assume that as seems plausible individuals do not know their pro les exactly at the beginning of life but learn in a bayesian way with successive income observations we nd that learning is very slow and aects consumption decision throughout the life cycle the model generates substantial rise in consumption inequality over the life cycle which matches empirical observations deaton and paxson 1994 moreover the shape of the age inequality pro le is non concave as in the data but unlike in a model with very persistent shocks finally the consumption pro les of college graduates are steeper than those of high school graduates in the model consistent with the data because they face a wider dispersion of and hence uncertainty about income growth rates overall this evidence indicates that income shocks may be signi cantly less persistent than what is currently assumed

crime rates and local labor market opportunities in the united states 1979 1997 the labor market prospects of young unskilled men fell dramatically in the 1980s and improved in the 1990s crime rates show a reverse pattern increasing during the 1980s and falling in the 1990s because young unskilled men commit most crime this paper seeks to establish a causal relationship between the two trends previous work on the relationship between labor markets and crime focused mainly on the relationship between the unemployment rate and crime and found inconclusive results in contrast this paper examines the impact of both wages and unemployment on crime and uses instrumental variables to establish causality we conclude that both wages and unemployment are significantly related to crime but that wages played a larger role in the crime trends over the last few decades these results are robust to the inclusion of deterrence variables controls for simultaneity and controlling for individual and family characteristics

identifying the impacts of rail transit stations on residential property values abstract prior studies that have empirically investigated the impact of rail station proximity on property values have not fully investigated the factors that may account for this relationship stations may raise the value of nearby properties by reducing commuting costs or by attracting retail activity to the neighborhood possibly countering these positive effects are negative externalities emitted by stations and the access to neighborhoods that stations provide to criminals this paper sorts out these effects by presenting the results from estimating a hedonic price model and auxiliary models for neighborhood crime and retail activity results show that all four effects play a role in defining the relationship between property values and rail stations but the relative importance of these effects varies with distance from downtown and the median income of the neighborhood

the costs of urban property crime this paper estimates the impact of recorded domestic property crime on property prices in the london area crimes in the criminal damage category have a significant negative impact on prices a one tenth standard deviation decrease in the local density of criminal damage adds 1 to the price of an average inner london property burglaries have no measurable impact on prices even after allowing for the potential dependence of burglary rates on unobserved property characteristics one explanation we offer here is that vandalism graffiti and other forms of criminal damage motivate fear of crime in the community and may be taken as signals or symptoms of community instability and neighbourhood deterioration in general

consumer demand and the life cycle allocation of household expenditures the purpose of this paper is to estimate the parameters of household preferences that determine the allocation of goods within the period and over the life cycle using micro data in doing so the authors are able to identify important effects of demographics labor market status and other household characteristics on the intertemporal allocation of expenditure they test the validity of the life cycle model using excess sensitivity tests and find that controlling for demographics and labor market status variables can largely explain the excess sensitivity of consumption to anticipated changes in income

valuing lost home production of dual earner couples using a life cycle model in which women divide their time between home and market work we establish a link between retirement wealth and the value of forgone home production we use data from the health and retirement study to estimate the model s parameters and adjust the growth rate of gdp to reflect reductions in non market output we find that the value of forgone home production is modest about 25 percent of women s measured earnings

home equity in retirement retired homeowners dissave more slowly than renters which suggests that homeownership affects retirees saving decisions we investigate empirically and theoretically the life cycle patterns of homeownership housing and nonhousing assets in retirement using an estimated structural model of saving and housing decisions we find first that homeowners dissave slowly because they prefer to stay in their house as long as possible but cannot easily borrow against it second the 1996 2006 housing boom significantly increased homeowners assets these channels are quantitatively significant without considering homeownership retirees net worth would be 28 44 lower depending on age

the un importance of chapter 7 wealth exemption levels this paper examines the effects of the chapter 7 wealth exemption level on welfare bankruptcy filings debt and on asset holdings i build a heterogeneous agent life cycle model which features uninsurable income and expense shocks moreover households can borrow and save simultaneously when a borrower defaults on her debt by filing for chapter 7 bankruptcy she can keep her assets up to the wealth exemption level wealth exemption levels are important for two reasons first they explain the extensive and intensive margin of the credit card debt puzzle around thirty percent of borrowers both in the model and in the data who borrow at high interest rates simultaneously save at low interest rates however these borrowers borrow and save only relatively small amounts a few thousand u s dollars second ignoring the exemption level biases results because it overstates the costs of defaulting the welfare gains from chapter 7 compared to the european system where debt is not discharged are twice as high when exemption levels are positive compared to when they are ignored at the same time wealth exemption levels are unimportant in the sense that they have an impact only at low exemption levels the effects of increases in the exemption level fade out very quickly there is no strong positive relationship between exemption levels which vary across u s states and default rates in the model this is in contrast to the previous literature but consistent with the data the reason is that those borrowers who might default do not own much wealth therefore only very few households are affected by increases in the exemption level

compensating differentials in emerging labor and housing markets estimates of quality of life in russian cities abstract the purpose of this paper is to see if an equilibrium model of compensating differences for amenities can be applied to a major transition economy russia we analyze russian labor and housing markets using data from the russian longitudinal monitoring survey rlms augmented by city and regional specific characteristics from other sources our estimated wage and housing value equations suggest that workers are compensated for differences in climate environmental conditions ethnic conflicts crime rates and health conditions after controlling for worker characteristics occupation industry and economic conditions and various housing characteristics we find evidence that these compensating differentials exist even after controlling for the regional pay differences regional coefficients used by the russian government to compensate public sector workers for living in regions that are designated as less desirable quality of life as measured by a group of eleven amenities varies substantially the highest ranked cities tend to be in relatively warm areas and areas in the western european part of the country our quality of life index is positively correlated with net migration into a region suggesting workers are attracted to amenity rich locations overall we find that a model of compensating differentials with controls for disequilibrium yields useful information about compensation for location specific amenities and quality of life in this large transition economy

the composition effect of consumption around retirement evidence from singapore abstract it is well established that consumption is hump shaped over an individual s lifecycle peaking in middle age and then declining in the years that follow prior research has documented that consumption declines at retirement which is inconsistent with the standard lifecycle model with consumption smoothing using a unique dataset with detailed administrative records of credit and debit card transactions we show the hump shaped lifecycle consumption pattern as documented in the literature additionally we show compositional changes in consumption expenditures across individuals in the years surrounding retirement confirming the results of aguiar and hurst 2005 2013

u s tax policy and health insurance demand can a regressive policy improve welfare abstract the u s tax policy on health insurance is regressive because it subsidizes only those offered group insurance through their employers who also tend to have a relatively high income moreover the subsidy takes the form of deductions from the progressive income tax system giving high income earners a larger subsidy to understand the effect of the policy we construct a dynamic general equilibrium model with heterogenous agents and an endogenous demand for health insurance a complete removal of the subsidy may lead to a partial collapse of the group insurance market reduce the insurance coverage and deteriorate welfare there is however room for improving the coverage and welfare by extending a refundable credit to the individual insurance market

towards a micro founded theory of aggregate labour supply we build a heterogeneous agents life cycle model that captures a large number of salient features of individual male labour supply over the life cycle by education both along the intensive and extensive margins the model provides an aggregation theory of individual labour supply firmly grounded on individual level micro evidence and is used to study the aggregate labour supply responses to changes in the economic environment we find that the aggregate labour supply elasticity to a transitory wage shock is 1 75 with the extensive margin accounting for 62 of the response furthermore we find that the aggregate labour supply elasticity to a permanent compensated wage change is 0 44

endogenous debt constraints in a life cycle model with an application to social security this paper develops a simple life cycle model that embeds a theory of debt restrictions based on the existence of inalienable property rights a la kehoe and levine 1993 debt constrained asset markets review of economic studies 60 4 865 888 2001 liquidity constrained markets versus debt constrained markets econometrica 69 3 575 598 in our environment net debtors have the option of defaulting on unsecured debt at the cost of being subjected to wage garnishment and or having some or all of their future assets seized by creditors one advantage of our framework is that it encompasses two standard versions of the life cycle model one with perfect capital markets and one with a non negative net worth restriction we study the impact of a payroll financed social security system to illustrate the role of endogenous debt constraints and compare our results to a model with exogenous debt constraints whereas the aggregate effects are similar under both types of constraints the distributional consequences are found to be significantly different across debt regimes

consumer bankruptcy a fresh start consumer bankruptcy provides partial insurance against bad luck but by driving up interest rates makes life cycle smoothing more difficult we argue that to assess this trade off one needs a quantitative model of consumer bankruptcy with three key features life cycle component idiosyncratic earnings uncertainty and expense uncertainty exogenous negative shocks to household balance sheets we find that transitory and persistent earnings shocks have very different implications for evaluating bankruptcy rules more persistent shocks make the bankruptcy option more desirable larger transitory shocks have the opposite effect our findings suggest the current us bankruptcy system may be desirable for reasonable parameter values jel d14 d91 k35

measuring the impact of crime on house prices this paper uses data on over 2800 house sales in jacksonville fl to estimate the impact of crime on house prices a gis programme is used to develop neighbourhood characteristics that are unique t

the method of endogenous gridpoints with occasionally binding constraints among endogenous variables we show how the method of endogenous gridpoints can be extended to solve models with occasionally binding constraints among endogenous variables very efficiently we present the method for a consumer problem with occasionally binding collateral constraints and non separable utility in durable and non durable consumption this problem allows for a joint analysis of durable and non durable consumption in models with uninsurable income risk which is important to understand patterns of consumption saving and collateralized debt we illustrate the algorithm and its efficiency by calibrating the model to us data

the individual life cycle annuity market imperfections and economic growth we study the effects of an annuity market imperfection on individual agents life cycle decisions and on the macroeconomic growth rate in an overlapping generations model with single sector endogenous growth our model features both age dependent mortality and labour productivity we model imperfect annuities by introducing a load factor on the annuity rate faced by finitely lived agents our main finding is that annuity market imperfections decrease economic growth because less assets are necessary for consumption late in life in addition we find that both the quantitative and qualitative effects of annuity market imperfections are grossly overestimated in a partial equilibrium analysis because it disregards general equilibrium repercussions

temptation and self control some evidence and applications this paper studies the empirical relevance of temptation and self control using household level data from the consumer expenditure survey we construct an infinite horizon consumption savings model that allows but does not require temptation and self control in preferences in the presence of temptation a wealth consumption ratio in addition to consumption growth becomes a determinant of the asset pricing kernel and the importance of this additional pricing factor depends on the strength of temptation to identify the presence of temptation we exploit an implication of the theory that a more tempted individual should be more likely to hold commitment assets such as individual retirement account ira or 401 k accounts our estimation provides empirical support for temptation preferences based on our estimates we explore some quantitative implications of this class of preferences for capital accumulation in a neoclassical growth model and the welfare cost of the business cycle

is there a compensating wage differential for high crime levels first evidence from europe abstract this paper investigates whether high regional crime levels lead to a compensating wage differential paid by firms in the respective region using data from german social security records official police statistics and official statistics for 2003 2006 i consider both violent and non violent crimes and use three way error components estimators to control for individual and regional heterogeneity the findings suggest that wages are practically unrelated to changes in crime rates this result is robust over a wide range of subgroups there is however some evidence that crime rates influence land prices

life insurance and household consumption abstract using life insurance holdings by age sex and marital status we infer how individuals value consumption in different demographic stages we estimate equivalence scales and bequest motives simultaneously within a fully specified model where agents face us demographics and save and purchase life insurance our findings indicate that individuals are very caring for dependents that economies of scale are large that children are very costly or yield very high marginal utility that wives with children produce lots of home goods and that females display habits from marriage while men do not these findings contrast sharply with standard equivalence scales

reverse mortgage loans a quantitative analysis reverse mortgage loans rmls allow older homeowners to borrow against housing wealth without moving despite rapid growth in this market only 1 9 of eligible homeowners had rmls in 2013 in this paper we analyze reverse mortgages in a calibrated life cycle model of retirement the average welfare gain from rmls is 252 per homeowner and 1 770 per rml borrower bequest motives uncertainty about health and expenses and loan costs account for low demand according to the model the great recession s impact differs across age income and wealth distributions with a threefold increase in rml demand for lowest income and oldest households

deconstructing life cycle expenditure we revisit two well known facts regarding life cycle expenditures the hump shaped profile of nondurable expenditures and the increase in cross household consumption inequality we document that the behavior of total nondurables masks surprising heterogeneity in the life cycle profile of individual consumption subcomponents we provide evidence that the categories driving life cycle consumption either are inputs into market work or are amenable to home production using a quantitative model we document that the disaggregated life cycle consumption profiles imply a level of uninsurable permanent income risk that is substantially lower than that implied by a model using a composite consumption good

intertemporal consumption durables and liquidity constraints a cohort analysis we provide a theoretical framework to analyse the response of life time maximizing consumers to intertemporal prices of non durable goods and durable goods when the borrowing limit depends on the market value of the stock of durables owned by the consumer we use pseudo panel data on purchases of non durables and durable goods cars and demographic characteristics from the uk family expenditure survey as well as estimates of the durable stock constructed using the uk national travel survey to estimate the equations derived in the first part of the paper we evaluate the shadow prices of these restrictions which were significantly positive for younger consumers in the mid seventies and immediately prior to the 1982 financial liberalisation

rising inequality changes in the distribution of income and consumption in the 1980s this paper examines changes in the distribution of income and consumption in the united states during the 1980s using data from the current population survey income and consumer expenditure survey consumption we reach three primary conclusions first changes in the distribution of consumption parallel changes in the distribution of income the lowest quintile of the consumption distribution received 0 9 percentage points less of total consumption in 1988 than in 1980 the corresponding decline for income was 0 6 percentage points second broad conclusions concerning recent changes in the consumption distribution are not very sensitive to the exact choice of a measure of family needs under a wide variety of alternative household equivalence scales there is a widening in the consumption distribution in the 1980s third the usc of consumption measures of well being in place of measures based on current money income docs change conclusions concerning the extent of poverty in the united stales using the official federal poverty thresholds we find that the overall consumption poverty rate was three percentage points below the income poverty rate in 1988 comparisons of the poverty rates of the elderly and the non elderly are substantially affected by the choice of poverty measure the consumption poverty rare for the elderly was only 60 percent of the rate for adults and one third of the rate for children in 1988 this abstract was borrowed from another version of this item

revisiting the effect of household size on consumption over the life cycle abstract although the link between household size and consumption has strong empirical support there is no consistent way in which demographics are dealt with in standard life cycle models we study the relationship between the predictions of the single agent model the standard in the literature versus a simple model extension the demographics model where deterministic changes in household size and composition affect optimal consumption decisions we show theoretically that the demographics model is conceptually preferable to the single agent model as it captures economic mechanisms ignored by the latter however our quantitative analysis demonstrates that differences in predictions for consumption are negligible across models when using standard calibration strategies this suggests that it is largely irrelevant which model specification is used

wages rents and the quality of life this study focuses on the role of wages and rents in allocating workers to locations with various quantities of amenities the theory demonstrates that if the amenity is also productive then the sign of the wage gradient is unclear while the rent gradient is positive the theory is extended to include the housing market and nontraded goods these extensions require little modification of the conclusion the empirical work on wages shows that the regional wage differences can be explained largely by these local attributes with the use of site price data implicit prices are estimated and quality of life rankings for the cities are computed

new estimates of quality of life in urban areas implicit markets capture compensation for intraurban and interregional differe nces in amenities and yield differences in housing prices and wages these pecuniary differences become preference based weights in a qual ity of life index hedonic equations are estimated using microdata fr om the 1980 census and assembled county based amenity data on climati c environmental and urban conditions ranking of 253 urban counties reveals substantial variation within as well as among the 185 urba n areas the quality of life differences across counties within one s msa is almost one half of the difference between the top and bottom ranked counties in the nation copyright 1988 by american economic association

gender differences in the cost of displacement an empirical test of discrimination in the labor market there are two competing explanations of why women workers earn less than men with equivalent education work experience and job tenure the human capital explanation and the discrimination explanation the human capital explanation argues that sex differences in human capital investment which arise from sex differences in expectations surrounding labor force participation account for the wage differential women workers are expected to invest less in jobspecific human capital than otherwise comparable men workers because women expect to spend less time on the job furthermore even for men and women workers with equal ex post levels of job tenure and or work experience women have invested less in onthe job training because their a priori expectations of job tenure and or work experience were less than those of men who now have the same tenure and or experience therefore in this view women workers earn less than comparable men because they have invested less in specific human capital women earn less because they are less productive the sex wage differential is economically efficient the discrimination explanation argues that sex differences in labor market opportunities that is sex discrimination in the labor market account for the sex wage differential in this view women workers earn less than comparable men because they are the victims of sex discrimination in the labor market women do not earn less because they are less productive the sex wage differential is economically inefficient while the economic implications of these two explanations of the sex wage differential are enormously different both explanations are consistent with empirical studies simply because both resort to nonmeasurables to explain the sex wage differential empirical studies cannot measure directly either discrimination or job specific human capital therefore the problem with these two competing explanations of the sex wage differential is that neither has been empirically sorted from the other both explanations are consistent with data which show a wage differential by sex after controlling for education work experience and job tenure newly available data on displaced workers provide an opportunity to empirically disentangle these two competing explanations of the sex wage differential displaced workers are workers who have lost their jobs either because their workplaces have closed or because they were permanently laid off due to slack demand for the outputs of their firms displaced workers represent a special case of worker mobility unlike voluntary job movers that is workers who have voluntarily quit their prior jobs the job mobility of displaced workers is not the result of their own expectations that better jobs are available a worker who voluntarily changes jobs does so because there is another job which offers higher wages or other improvements in the conditions of employment the worker moves precisely because his or her productivity and wages is higher on the subsequent job the wage change is endogenous unlike workers who are fired or involuntarily laid off because their personal productivity is lower than that of other tdiscussants rebecca blank princeton university elyce rotella indiana university

humps and bumps in lifetime consumption in this article we argue that the life cycle model that allows demographics to affect household preferences and relaxes the assumption of certainty equivalence can generate hump shaped consumption profiles over age that are very similar to those observed in household level data sources and in particular match the differences in shape across different education groups liquidity constraints or myopia are not required to explain the empirical features of observed life cycle patterns

yours mine and ours do divorce laws affect the intertemporal behavior of married couples divorce laws establish spouses individual property rights over household resources and determine when divorce is allowed this paper examines how such laws inuence the intertemporal behavior and the welfare of u s married couples i build a model of household choice about consumption labor supply and divorce under multiple divorce law regimes and i estimate it using exogenous variation in u s divorce laws from the 1970s to the 1990s couples responded to equal division of property and unilateral divorce by increasing tangible assets up to 19 which suggests the presence of a strong income eect for the primary earner and by reducing female employment by over 5 percentage points because the threat of divorce granted additional bargaining power to married woman the bargaining weight of women implied by these responses in the model corresponds to a third of the weight of men this indicates that equal division of assets beneted women when it was

optimal timing of college subsidies enrollment graduation and the skill premium abstract the large increase in the skill premium has led many policy makers to propose increasing college subsidies as a strategy to increase college enrollment and reduce inequality existing analyses typically assume that there is no distinction between enrollment and graduation but in fact more than 50 of college enrollees do not graduate this highlights the need to explicitly model the decision to drop out in assessing the effect of subsidies i build a general equilibrium model of education choice that features an explicit dropout decision calibrate it to match key features of the us economy and use it to evaluate the impact of college subsidies on the supply of college educated labor i show that moving to a system in which subsidies are back loaded i e higher for juniors and seniors than for freshmen and sophomores will increase the supply of college educated labor even holding total subsides constant in fact this effect is larger than what would be accomplished by a uniform 50 increase in subsidies

growth and saving among individuals and households the lifecycle theory of saving and consumption predicts that changes in an economy s rate of economic growth will affect its aggregate saving rate by changing the lifetime resources of younger people relative to older people however studies that track the saving behavior of cohorts of household heads over time as they age have yielded estimates of age saving profiles that are too flat for growth to have much effect on the aggregate saving rate one problem with the cohort approach is that multigenerational households are common in many counties and the age saving profiles of households may be quite different from the age saving profiles of individuals that make up households in this paper we propose a method for estimating individual age saving profiles using household data this method is applied to data from taiwan and thailand we find that the individual method yields results that are more favorable to the lifecycle model these results imply that changes in the rate of economic growth may in som

life cycle preferences revisited an axiomatic construction for life cycle preferences accounting for the finiteness and the randomness of life duration is provided we emphasize the role of intertemporal correlation aversion and explain why multiplicative preferences provide an interesting alternative to additive preferences allowing risk aversion and intertemporal elasticity of substitution to be separated implications regarding the shape of the optimal consumption profiles are discussed

social security and old age unemployment risk with efficient wage bargaining i analyze a life cycle economy with old age productivity risk where wages employment and severance payments are set through efficient bargaining between risk averse unions and risk neutral firms allocations with limited union membership are second best inefficient as they generate too little labor supply in young age too much consumption before retirement too little employment of older workers early retirement and too little insurance against old age unemployment providing public transfers to early retirees disability benefits or early pensions might help to increase the degree of risk sharing at the cost of lower old age employment depending on whether absolute risk aversion is increasing or decreasing in consumption these policies might or might not produce efficiency gains at equilibrium

valuing school quality better transport and lower crime evidence from house prices housing prices within urban areas exhibit highly localized variation that cannot be explained solely by differences in the physical attributes of dwellings we consider the role of local amenities and disamenities in generating price variation within urban areas focusing on three highly policy relevant urban issues transport accessibility school quality and crime our survey of the recent empirical literature highlights what is known and what is not known on these issues and considers the relevance and reliability of this evidence for policy design and evaluation although there are serious empirical challenges we argue that research on housing values based on careful research designs can offer credible estimates of the social value of place specific attributes and amenities

demographics and the natural interest rate in the euro area abstract we investigate the impact of demographics on the natural rate of interest nri in the euro area with a particular focus on the role played by economic openness migrations and pension system design to this end we construct a life cycle model and calibrate it to match the life cycle profiles from hfcs data we show that population aging contributes significantly to the decline in the nri explaining about two thirds of its secular decline between 1985 and 2030 openness to international capital flows has not been important in driving the ea real interest rate as aging in europe has been similar to that in the rest of the world so far of two possible pension reforms only an increase in the retirement age can revert the downward trend on the equilibrium interest rate while a fall in the replacement rate would make the decline in nri even deeper the demographic pressure on the eurozone nri can be alleviated by increased immigration but only to a small extent and with a substantial lag

consumption over the life cycle facts from consumer expenditure survey data this paper uses consumer expenditure survey data and a seminonparametric statistical model to estimate life cycle profiles of consumption controlling for demographics cohort and time effects we construct age profiles for total and nondurable consumption as well as expenditure patterns for consumer durables special emphasis is placed on the comparison of different approaches to control for changes in demo graphics over the life cycle we find significant humps over the life cycle for total nondurable and durable expenditures changes in household size account for roughly half of these humps bootstrap simulations suggest that our empirical estimates are tight in that standard errors are small

full insurance in the presence of aggregate uncertainty this paper tests implications of full consumption insurance the object is to determine how much mileage can be obtained from a model with complete markets with such features as private information or liquidity constraints omitted the implication exploited is that individual consumption responds to aggregate risk but not to idiosyncratic risk the test involves regressing the change in household consumption onto the change in aggregate consumption and other right hand side variables such as the change in household income and change in employment status all variables other than the change in aggregate consumption are predicted to be insignificant in explaining the change in household consumption with observations on consumption and income for 10 695 households from the consumer expenditure survey the results are mixed the results for one specification exponential utility are mostly consistent with full consumption insurance the results for the other specification power utility are not

wages rents and amenities differences among workers and regions what explains persistent regional earnings differences this paper argues that regional differences in amenities can account for the wage differences in contrast cost of living variations do not account for wage differences but actually exacerbate them this conclusion results from a model in which variations in rents and wages are equalizing differences for amenity differences empirical results are consistent with the model

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

why has house price dispersion gone up we calibrate a dynamic general equilibrium island model to investigate the 30 year increase in the level of house prices and their dispersion across u s metropolitan areas the model is based on two main assumptions households o w in and out metropolitan areas in response to local productivity shocks and the housing supply cannot adjust instantly because of technological and regulatory constraints the calibration reveals that the observed tightening of housing supply regulation cannot quantitatively account for the rise in the level and dispersion of house prices in equilibrium workers o w out of tightly regulated towards less regulated metropolitan areas undoing most of the price impact of local supply restrictions in contrast the observed increase in wage dispersion across metropolitan areas does create the observed increase in the level and dispersion of house prices workers o w towards exceptionally productive metropolitan areas and drive house prices up the calibration also suggests that the welfare eects of housing supply regulation are large when wages become more dispersed

the link between crime risk and property prices in england and wales evidence from street level data this paper uses street level data on property sales and crime rates for england and wales to investigate compensating differentials for crime risk my identification strategy relies on the use of non parametric regional time trends on various levels of spatial aggregation as well as various fixed effects for streets and wider areas to control for unobserved amenities and regional economic conditions the data comes from transaction data collected by the land registry and recently published crime maps for the whole of the uk my estimates which are robust to a range of sensible specification changes suggest that each case of anti social behaviour per ten population in the same street leads to an approximately 0 6 0 8 drop in property prices while a corresponding increase in violent crime decreases prices by roughly 0 6 1 6 and a corresponding increase in non violent crime by about 0 2 0 4 the majority of estimates are at the upper end of these intervals estimates for robbery burglary and vehicle c

accounting for the gender gap in college attainment i introduction one striking phenomenon in the u s labor market is the reversal of the gender gap in college attainment in 1980 57 of young men aged 25 34 compared with 46 of young women had some college education by age 34 by 1996 however female college attainment had reached 64 5 percentage points higher than that of the males in the same cohort in tact females overtook males in college attainment in 1987 and have led ever since a large body of empirical research emphasizes the role of the earnings premium as a key explanatory variable for the determination of education outcomes see e g becket 1967 mincer 1974 willis and rosen 1979 in addition an extensive literature shows that family background is an important determinant of the schooling decision see among others cameron and heckman 1998 2001 eckstein and wolpin 1999 ge 2008 kane 1994 recently several papers have argued empirically and theoretically that expected marriage is important in determining the schooling decision e g chiappori iyigun and weiss 2006 ge 2008 iyigun and walsh 2007 on the basis of this literature we construct a life cycle model that includes potential costs and benefits from the labor market and marriage market which determine individual college decisions in our model individuals with differing learning abilities first decide whether or not to enter college then they might get married and have children parents are altruistic and value their children s learning ability which increases with the parents education forward looking individuals take into account the impact of their own schooling on their children s learning ability other factors that affect an individual s decision on whether to pursue higher education include the expected direct labor market returns to college over one s lifetime the expected marriage market returns to college and the financial and effort costs of attending college these costs and benefits can differ by gender we calculate from panel study of income dynamics psid and current population survey cps parents education distributions the life cycle profiles of single marriage and divorce probabilities by education and the lifecycle profiles of earnings by education and marital status as exogenous inputs of the model we observe that the number of college educated parents increases over time in the marriage market a substantial increase of single probabilities and an increase of divorce probabilities has occurred for both genders regardless of college attainment status lifetime earnings by cohort are decreasing slowly for males of all marital statuses especially for married males lifetime earnings for married and divorced females are increasing gradually whereas those for single females are decreasing slightly to formally endogenize those changes is beyond the scope of our paper we instead focus on the mechanism in which under perfect foresight these changes affect education decisions we estimate the parameters of the model by matching data on college attainment by gender from the psid we present evidence on how well the model fits the data we then use the parameter estimates to simulate counterfactual experiments which break down the sources of changes in college attainment into the effects of changes in relative earnings changes in parental education and changes in the marriage market what accounts for the increase in college attainment over the past few decades we find that the increasing gap in earnings between college and high school graduates has important effects on the increase in college attainment for both genders when earnings are fixed at 1946 cohort levels attainment rates in 1996 drop by 15 5 and 14 2 percentage points for males and females respectively we also emphasize the importance of intergenerational persistence in schooling on the increase in college attainment for both genders

compensating differences and interregional wage differentials interregional differences in average wages and earnings have been observed particularly in the north and south of the united states ever since the mid 1800s that observation has motivated several empirical attempts to determine the source of those differentials measured both in nominal and real terms and to explain why they have been maintained over time the general conclusion reached by the overwhelming majority of these studies is that the labor market has not eliminated these wage differentials even in the face of substantial interregional migration this result has at least two alternative interpretations first it would appear to contradict the theory of compensating differences as applied to the labor market thaler and rosen 1975 which stresses that under the assumptions of perfect information free geographic and intersectoral labor mobility and homogeneous consumer tastes the nominal wage rates of workers who have similar human capital characteristics live and work in similar environments and experience similar living costs are driven to equality second this result may only reflect an aggregation error in other words there may be several types of labor that are each paid different equilibrium wage rates and comprise different percentages of the workforce in each region even if the real wage paid to each class of workers is interregionally invariant a situation that instead would support the theory of compensating differences failure to distinguish accurately between labor types could produce the illusion of a wage differential this paper considers the two alternative interpretations given above as to why interregional wage differentials might exist hedonic real wage equations are estimated for four regions of the united states using observations on individual household heads drawn from the 1976 panel study in income dynamics psid this sample is of interest because the 1976 psid data contain unusually detailed measures of education work experience and occupation as well as information on workplace and job characteristics thus a more complete specification of the wage equation is permitted and the possibility of aggregation error is reduced particularly in comparison with other interregional wage differential studies several of these studies for example have been based on aggregate data from the census of manufactures fuchs and perlman 1960 gallaway 1963 scully 1969 and coelho and ghali 1971 which provide no direct measurements on the human capital of workers the remainder of the discussion is organized into three sections section ii specifies the wage equation and describes the psid data section iii then reports empirical results which are consistent with the findings based on aggregate data of bellante 1979 and coelho and ghali 1971 in that they support the theory of compensating differences more specifically for full time workers the rewards to attributes relevant in determining real wages apparently are interregionally invariant however because this result conflicts with most previous research on interregional wage differentials based on aggregate data and virtually all such research based on microdata welch 1966 hanoch 1967 hanushek 1973 1981 hirsch 1978 and sahling and smith 1983 a number of empirical comparisons are made between the present study and the approaches taken by other investigators conclusions and implications are drawn out in section iv

local amenities and life cycle migration do people move for jobs or fun abstract do households move for jobs or fun and where do they go when they move we address these questions using the 1970 2000 us census based on a panel of quality of life and business environment measures households prefer msas in warm coastal areas and non metropolitan locations while firms prefer large growing cities in addition cities with improving business environments acquire increasing shares of workers especially workers with high levels of human capital cities with improving consumer amenities become relatively more populated by retirees further analysis of individual level migration decisions indicates that regardless of marital status young highly educated households tend to move towards places with higher quality business environments this tendency is especially pronounced among highly educated couples who are more subject to job market co location problems in contrast regardless of education couples near retirement tend to move away from places with favorable business environments and towards places with highly valued consumer amenities these patterns help explain why areas unattractive to both households and business have struggled as with upstate new york while the sun belt and other regions are thriving

household economies of scale in consumption theory and evidence household economies of scale arising from the existence of househo ld public goods increasing returns in household production and or bulk discounts are incorporated into a utility theoretic model of household demands individuals are assumed to be identical and symmetrically treated within households economies of scale parameters for five goods are estimated using the quadratic expenditu re system and data from the u s consumer expenditure survey on expenditures by all adult households results suggest the existence o f significant economies of scale in the consumption of all of the included goods with economies being especially pronounced in the consumption of shelter copyright 1988 by the econometric society

a cohort analysis of saving behavior by u s households the aim of this paper is to shed some light in the decline in personal saving rates in the united states in the 1980s for a such a purpose the paper analyses the only u s data set containing information on consumption and income at the household level the consumer expenditure surveys cex from 1980 to 1991 because the cex is not a panel most of the analysis is conducted using average cohort techniques the paper identifies a typical age profile for saving rates such a profile is hump shaped and peaks around age 57 the paper also argues that such a profile was shifted down for the cohorts born between 1920 and 1939 relative to the younger and older cohorts considered these cohorts are the parents of the baby boom generation the paper also argues that these cohort effects can account for a non neglible proportion of the decline in aggregate saving because these cohorts were during the 1980s in the ages when saving rates are typically highest the result is robust to the consideration of several controls and holds for several definitions of consumption the only exception is when durable expenditure is considered as saving rather than consumption

worker investments in safety workplace accidents and compensating wage differentials the theory of compensating wage differentials cwds assumes that firms supply and workers demand workplace safety predicting a positive relationship between accident risk and wages this article allows for safety provision by workers which predicts a countervailing negative relationship between individual risk and wages firms pay higher wages for higher safety related productivity using national longitudinal survey of youth panel data and data on fatal and nonfatal accidents our precise cwds imply a value of a statistical injury of 45 4 thousand and a value of a statistical life of 6 3 million in line with our model individual risk and wages are negatively correlated

empirical evidence on the trade impact of asynchronous regulatory approval of new gmo events abstract this paper focuses on the ex post empirical analysis of the trade impact of asynchronous regulatory approval of new genetically modified organism gmo events we contribute to the literature in three ways first we define indices to assess the extent of asynchronicity and the relative strictness of the gmo approval authorizations of 40 countries considering gmo regulatory developments between 2000 and 2012 regarding cotton maize and soybeans second we introduce indices that are country pair specific product specific and year specific in a gravity model to examine the trade impact of asynchronous regulatory approval across countries by grouping the countries according to the state of their national regulatory gmo frameworks we have an even more differentiated view on the trade impact of asynchronous approval that focuses not only on the existence of regulations but also on their restrictiveness the results from the gravity model show that asynchronous approval has negatively impacted trade flows of cotton maize and soybeans it is observed that both asynchronous approvals and the restrictiveness of importing countries regulations to address the importation of gmo products matter meaning those countries that have already adopted a comprehensive gmo regulatory framework and have policies to manage the importation of gmo crops tend to feel a higher negative impact on trade flows

optimal life cycle unemployment insurance we argue that us welfare would rise if unemployment insurance were to be increased for young workers and decreased for old this is because young workers have little means to smooth consumption during unemployment and want jobs to accumulate high return human capital so unemployment insurance is highly valuable to them while the induced moral hazard problem is mild we consider a life cycle model with unemployment risk and endogenous search eort that we calibrate to match us labor market institutions we nd that allowing unemployment replacement rates and other government transfers to decline with age yields sizeable welfare gains which amount to around two thirds of the gains attained under the constrained optimal scheme for unemployment insurance over the life cycle

the age specific burdens of short run fluctuations in government spending abstract we study the impact of government spending shocks on the distribution of income and wealth between cohorts and the associated welfare effects in a dynamic stochastic overlapping generations model with two types of households ricardian households and rule of thumb consumers we demonstrate that an unexpected increase in government spending decreases income and wealth inequality in contrast to the conventional wisdom that the financing of government expenditures by debt rather than taxes especially burdens young generations we find that debt financing also harms ricardian households during retirement the crucial element in our analysis is a wealth effect that results from the decline in the price of capital due to higher government debt

testing for educational credit constraints using heterogeneity in individual time preferences i develop a model in which individual time discount rates have a larger effect on human capital accumulation when credit constraints are binding impatient individuals obtain less schooling when borrowing constraints limit the ability to finance consumption during school using data from the nlsy79 i show that self reported measures of time preferences have a significantly higher effect on the college attendance decisions of blacks than those of whites and the decisions of low income youths than those of high income youths these results provide new evidence that members of disadvantaged groups obtain lower levels of schooling because they are credit constrained

adjustment of consumers durables stocks evidence from automobile purchases this paper tests an optimal s s rule in household durable purchases and examines directly the resulting aggregate expenditure dynamics the observed decision rule responds to income uncertainty and growth as predicted by an s s model resulting from transactions costs tests against liquidity constraints find that about half the households purchase according to an optimal s s rule aggregating the s s rule over households produces a cross section distribution of durables holdings the empirical distribution is similar to that predicted theoretically as is its response to aggregate shocks furthermore simulations of aggregate expenditure based on the household distribution exhibit dynamics consistent with those observed in the 1980s

housing over time and over the life cycle a structural estimation we estimate a structural model of optimal life cycle housing and nonhousing con sumption in the presence of labor income and house price uncertainties the model postulates constant elasticity of substitution between housing service and nonhousing consumption and explicitly incorporates a housing adjustment cost our estimationts the cross sectional and time series household wealth and housing proles from the panel study of income dynamics 1984 to 2005 reasonably well and suggests an intratemporal elasticity of substitution between housing and nonhousing consumption of 0 487 the low elasticity estimate is largely driven by moments conditional on state house prices and moments in the latter half of the sample period and is robust to different assumptions of housing adjustment cost we then conduct policy analyses in which we let house price and income take values as those observed between 2006 and 2011 we show that the responses depend importantly on the housing adjustment cost and the elasticity of sub stitution between housing and nonhousing consumption in particular compared with the benchmark the impact of the shocks on homeownership rates is reduced but the impact on nonhousing consumption is magnied when the house selling cost is sizable or when housing service and nonhousing consumption are highly substitutable

aggregate consumer behavior and household equivalence scales this article presents estimates of household equivalence scales broken down by demographic characteristics of u s households separate estimates are given by family size age of head region race and urban versus rural residence commodity specific scales are presented for five separate commodity groups energy food consumer goods capital services and other services the estimates are obtained from an econometric model of aggregate consumer behavior the parameters of this model are estimated by combining aggregate time series and individual cross section data

crime and the timing of work abstract two striking facts describe work timing in the united states a lower propensity to work evenings and nights in large metropolitan areas and a secular decline in such work since 1973 one explanation is higher and possibly increasing crime in large areas i link current population survey data on work timing to fbi crime reports neither fact is explained by changes in nor inter area differences in crime rates but higher homicide rates do reduce such work this reduction implicitly costs the economy between 4 and 10 billion this negative externality illustrates a larger class of previously unmeasured costs of social pathologies

consumption over the life cycle and over the business cycle the main aim of this paper is to assess the validity of the life cycle model of consumption in particular we address an issue that has recently received much attention especially in the macroeconomic literature that of excess sensitivity of consumption growth to income growth we do this using a time series of cross sections and a novel and flexible parameterization of preferences the former allows us to address aggregation issues directly while with the latter we can allow both the discount factor and the elasticity of intertemporal substitution eis to be affected by various observable variables and lifetime wealth the main findings can be summarized as follows i the excess sensitivity of consumption growth to labor income disappears when we control for demographic variables this is true both at life cycle and business cycle frequencies ii estimation of a flexible specification of preferences indicates that the elasticity of intertemporal substitution is a function of several variables including the level of consumption the eis increases with the level of consumption as expected iii the variables that change the eis are also important in explaining why we observe excess sensitivity over the business cycle iv we are able to reconcile our results with those reported both in the macro and micro literature v in our specification the elasticity of intertemporal substitution is not very well determined this result however should be taken with care as we have not made an effort to construct a preferred specification which would probably include additional controls for labor supply behavior the evidence presented shows that the life cycle model cannot be easily dismissed indeed we believe that the model does a good job at representing consumption behavior both over the life cycle and over the business cycle
