unanticipated aggregate disturbances and tests of the life cycle consumption model several recent studies have used data on food consumption from the panel study of income dynamics psid to test t he rational expectations life cycle hypothesis against the alternative of prevalent liquidity constraints these tests invoke the rational expectations restriction that income forecast errors are independent of lagged information this restriction however applies only in a time series context it is possible that unanticipated macroeconomic disturbances cause forecast errors to be correlated with lagged information in a cross section of families the authors present evidence of such a correlation in the psid data show that this correlation biases previous tests of the life cycle model toward rejection and derive a proper test of the life cycle model using pa nel data copyright 1993 by mit press

are ghettos good or bad spatial separation of racial and ethnic groups may theoretically have positive or negative effects on the economic performance of those groups we examine the effects of segregation on outcomes for blacks in schooling employment and single parenthood we find that blacks in more segregated areas have significantly worse outcomes than blacks in less segregated areas we control for the endogeneity of location choice using instruments based on political factors topographical features and residence before adulthood a one standard deviation decrease in segregation would eliminate one third of the black white differences in most of our outcomes

soft skills hard skills and the black white wage gap this study examines the relative importance of soft skills versus hard skills across occupations and its impact on the observed wage gap between blacks and whites in the united states it posits that the black white pay gap may vary across occupations that require the use of different types of skills we classify occupations into hard skill intensive versus soft skill intensive jobs using the skill content measures of different occupations from the occupational information network o net we then use data from the national longitudinal survey of youth nlsy and current population survey cps to investigate the impact of job skill type on the wage gap consistent with our theoretical predictions we show that this wage gap in white collar jobs is smaller for hard skills jobs than it is for soft skills jobs moreover we demonstrate that in response to variations in the wage gap across different occupations blacks are more likely to self select themselves into hard skills jobs ceteris paribus this shows not only that discrimination against blacks varies across occupations but also that such discrimination induces the self selection of blacks into certain occupations moreover this finding highlights the role played by co worker customer discrimination in explaining the racial wage gap in the u s labor market jel j15 j31

what went wrong the erosion of relative earnings and employment among young black men in the 1980s this paper shows a widening in black white earnings and employment gaps among young men from the mid 1970s through the 1980s earnings gaps increased most among college graduates and in the midwest while gaps in employment population rates grew most among dropouts we attribute the differential widening to shifts in demand for subgroups due to shifting industry and regional employment the falling real minimum wage and deunionization the growing supply of black to white workers that was marked among college graduates and to increased crime among dropouts the different factors affecting subgroups highlight the economic diversity of black americans

black residential centralization and the spatial mismatch hypothesis abstract black residential centralization is found to be an important determinant of black employment status when estimated across metropolitan areas mas to avoid neighborhood selection the effects are greatest in large mas for the young and elderly and for individuals with less than a college education instrumental variable iv estimates support ordinary least squares ols results black residential centralization can account for 48 62 of the black white employment differential among 18 30 year olds living in large mas when estimated together black residential centralization job centralization and segregation all have large effects but the effects of black centralization and job centralization are considerably larger

residential segregation discrimination and african american theater entry during jim crow abstract we examine the effect of residential segregation on the entry of movie theaters serving african american customers in the 1950s which provided an alternative to the segregated theaters of the jim crow era consistent with preference externalities in racial and ethnic enclaves we find that greater residential segregation was associated with more african american theater entry estimates from a model of firm entry indicate that residential segregation increased the variable profits of african american movie theaters reducing the market size required for theater entry by 13 3 percent for a one standard deviation increase in segregation we also provide evidence that racial bias increased both variable profits and fixed costs and on net reduced african american theater entry an interpretation consistent with this finding is that racial animus forced black customers toward segregated accommodations while also limiting access to key inputs for potential entrants

an analysis of the correlates of discrimination facing young hispanic job seekers this study examines the extent and correlates of discrimination faced by young accented hispanic males in chicago and san diego using the outcomes of job applications by matched pairs of anglo and hispanic job seekers this is one of the first examples of audits being used in the labormarket area the audit methodology provides a powerful basis for examining discriminatory hiring practices because it permits direct comparison of hiring outcomes for pairs of anglo and hispanic jobseekers with similar labor market qualifications in this paper we first present differences in anglo hispanic success rates in filing applications obtaining interviews and obtaining jobs this builds on the descriptive analysis presented in harry cross et al 1990 we then focus on the correlates of differential success in obtaining interviews and in subsequent job acquisition i the audit methodology

intrametropolitan variation in wage rates the case of atlanta fast food restaurant workers this paper utilizes a unique data base to provide some rare evidence on wage variation within a metropolitan area positively sloped wage gradients are found for both black and white employees of fast food restaurants in atlanta georgia blacks are found to work on that portion of the gradient where wage rates are lowest evidence on discrimination suggests that consumer prejudice affects the wages paid to black workers as distance from the central business district center increases the positive wage gradient effect is found to strongly dominate the negative effect on wages from greater consumer discrimination copyright 1994 by mit press

customer discrimination and employment outcomes for minority workers this paper investigates the effects of customer discrimination on the employment and earnings of minorities particularly blacks data are used from a new survey of employers in four large metropolitan areas in the united states our results show that the racial composition of an establishment s customers has sizable effects on the race of who gets hired particularly in jobs that involve direct contact with customers and in sales or service occupations race of customers also affects wages with employees in establishments that have mostly black customers earning less than those in establishments with mostly white customers

employer demand for welfare recipients by race this article examines employer demand for welfare recipients using new employer survey data the results suggest that demand is high but sensitive to business cycle conditions factors including skill needs and industry affect prospective employer demand for recipients while other characteristics that affect their relative supply to employers e g establishment location influence whether such demand is realized in actual hiring the conditional demand for black and hispanic welfare recipients lags behind their representation in the welfare population and seems affected by employers location and indicators of preferences thus many demand side factors limit the employment options of welfare recipients especially minorities

job queues and wages this paper uses job applications data to investigate the relationship between job queues and wage differentials the main finding is that openings for jobs that pay the minimum wage attract more job applicants than jobs that pay either slightly more or slightly less than the minimum wage this spike in the job application rate distribution suggests that ex ante rents generated for employees by an above market level minimum wage are not completely dissipated by reductions in nonwage benefits in addition we find that highly unionized firms large firms and firms in high wage industries tend to receive relatively many job applicants for openings

identity trust and altruism an experiment on preferences and microfinance lending abstract we conduct laboratory and online experiment treatments to study willingness to lend potential crowd out of philanthropic motivation by financial returns and preference over borrowers in micro finance lending we distinguish between perceptions of transaction related factors such as neediness and trustworthiness and identity related factors such as ethnicity and gender by looking at both channels together we are able to assess the extent to which identity related differences in lending can be attributed to differences in how transaction related factors are perceived among people with similar and different identities we find that 1 both financial return and philanthropic motivation affect the amount lent with little evidence that the former crowds out the latter 2 lenders prefer borrowers with whom they share gender and ethnic similarity even after controlling for perceived riskiness and neediness and 3 lenders are willing to trade greater risk in order to help more needy borrowers but at a rate sensitive to their own degree of financial exposure lack of crowding out homophily effects in some subgroups and robustness to decision order are found in additional treatments with three subject pools including one of non student participants

short and long run asymmetric effect of oil prices and oil and gas revenues on the real gdp and economic diversification in oil dependent economy abstract the aim of this paper is to explore the short and long run asymmetric impact of oil prices shocks and oil and gas revenues changes on the total real gdp and the level of economic diversification of the qatar economy to this end two econometric approaches have been used 1 the a b structural vector autoregressive ab svarx model with exogenous variables where four different asymmetric oil prices and oil and gas revenues measures have been employed and 2 the nonlinear autoregressive distributed lag nardl model the results show that in the short run the responses of both total real gdp and non oil real gdp to negative shocks on real oil prices and real oil and gas revenues are higher than the impact of positive shocks indicating evidence for the existence of asymmetric impact of shocks in the short run however the results suggest that the impact of shocks do not last more than three quarters this evidence for the existence of asymmetric behavior is also confirmed by the nardl analysis which shows that in the long run positive oil prices shocks and oil and gas revenues changes have higher impact on the two proxies of economic activity than negative changes do a result that confirms the resilience of the qatar economy to negative shocks and the positive role played by the energy sector in improving the qatar economic diversification degree finally the results show that the non oil sector is completely resilient to negative shocks in the long run as the impact of negative shocks are insignificant on the non oil real gdp several policies aimed to improve the level of economic diversification of the country and delink the government revenues from oil and gas revenues are proposed and discussed

the effects of competition and equal treatment laws on gender wage differentials discrimination if it is inefficient can be eliminated by competition in most countries it is also forbidden by law this paper evaluates the influence of economic and legal factors on the portion of male female wage differentials that is not explained by other worker characteristics and may be due to discrimination we use a new international data set of suitable gender wage gap measures constructed from the results of existing studies meta analysis of the data shows that increased competition and adoption of international conventions concerning equal treatment laws both reduce gender wage gaps while legislation that prevents women from performing strenuous or dangerous jobs tends to increase it doris weichselbaumer and rudolf winter ebmer

customer racial discrimination in the market for memorabilia the case of baseball because consumer discrimination can reduce productivity it is often impossible to tell whether differential productivity is the effect of discrimination or of differential ability detailed data for the sports labor market make it possible to separate consumer discrimination from ability we use a unique approach to determine whether the entertainment value of baseball players is related to their race we examine whether race directly affects the value of a player in the market for baseball cards in contrast to studies that use salaries there is no room for owner or coworker discrimination our evidence supports the hypothesis of consumer discrimination

racial wage inequality job segregation and devaluation across u s labor markets1 despite decades of research showing greater black white inequality in local areas where the black population is relatively large little is known about the mechanisms for this effect using a unique data set of individuals nested within jobs across labor markets this article tests two possible mechanisms for the black concentration effect on wage inequality job segregation and devaluation results show that black population size is associated with greater segregation of black workers into black dominated jobs on the other hand no evidence is found that the penalty for working in a black dominated job the devaluation effect increases as a function of black population size the article concludes that discrimination against workers especially exclusion from better paying jobs is an important mechanism for the effect of black population size on the racial wage gap

the incidence of mandated maternity benefits i consider the labor market effects of mandates which raise the costs of employing a demographically identifiable group the efficiency of these policies will be largely dependent on the extent to which their costs are shifted to group specific wages i study several state and federal mandates which stipulated that childbirth be covered comprehensively in health insurance plans raising the relative cost of insuring women of childbearing age i find substantial shifting of the costs of these mandates to the wages of the targeted group correspondingly i find little effect on total labor input for that group jel 118 j32 h51 in an era of tight fiscal budget constraints mandating employer provision of workplace benefits to employees is an attractive means for a government to finance its policy agenda consequently in recent years there has been a growth of interest in mandated benefits as a tool of social policy for example the centerpiece of president bill clinton s health care proposal is mandated employer provision of health insurance and more than 20 states have man

sex discrimination in restaurant hiring an audit study in an audit study of sex discrimination in hiring comparably matched pairs of men and women applied for jobs as waiters and waitresses at restaurants in philadelphia in high price restaurants where earnings are higher job applications from women had an estimated probability of receiving a job offer that was lower by about 0 4 and an estimated probability of receiving an interview that was lower by about 0 35 both estimated differentials are statistically significant additional evidence suggests that customer discrimination partly underlies the hiring discrimination

customer discrimination and affirmative action i introduction beginning with the work of becker 1957 economists have been concerned with the relationship between competitive market forces and the persistence of labor market discrimination 1 a major insight of becker and the literature that followed is that competition could tend to eliminate discriminatory pay differentials if competitive forces do eliminate discrimination then empirical findings of persistent discrimination are either a result of faulty testing or market imperfections economic analysis of the link between competition and discrimination depends on the origins of prejudice becker identified at least three possible sources employers co workers and consumers 2 in each of these instances the group against which prejudice is directed e g women or minorities which will be termed minorities in this paper may be able to escape discrimination first minorities can work for nondiscriminatory employers if there are any moreover stiglitz 1973 shows that with constant returns to scale such employers will take over markets from the discriminators eliminating any pay gap based on prejudice 3 second if there is co worker prejudice then minorities can work in segregated firms which under constant returns to scale may have a cost advantage over integrated or all majority firms again discrimination will be driven away 4 third minorities can theoretically escape customer discrimination by specializing in the production of goods for which there is no contact between producers and consumers a case discussed by cain 1986 while competitive forces may in some cases erode discriminatory wage differentials the rate of decline of race and sex wage differentials has evidently not been rapid enough in the eyes of policymakers u s anti discrimination policy has been guided by two major vehicles title vii of the 1964 civil rights act and the office of federal contract compliance programs ofccp 5 the equal employment opportunity commission eeoc was created to enforce title vii and is empowered to aid plaintiffs or bring suit itself against employers the commission monitors the employment practices of federal contractors not only are contractors barred from discrimination against protected groups these firms are also required to take affirmative action not to discriminate the purpose of this paper is twofold first it demonstrates that in a general equilibrium framework the case of customer discrimination is theoretically distinct from employer or co worker prejudice in particular while constant returns to scale and the existence of nondiscriminatory firms can eliminate the latter two forms of discrimination customer discrimination may persist even under such conditions the persistence of discriminatory wage differentials is shown to depend on consumer demand technology and the relative size of the minority labor force 6 second the general equilibrium framework is then used to evaluate the impact of government anti discrimination policy where customers are the source of discrimination it is shown that if the government requires equal pay and proportional representation for minorities then the resulting allocation of resources will under particular assumptions be the same as if customers did not discriminate i then contrast these theoretical results with the predicted general equilibrium impact of affirmative action when there is employer or co worker prejudice among previous general equilibrium models of affirmative action welch 1976 assumed no discrimination while freeman 1978 did not specify the source of discrimination it is shown here that the source of prejudice markedly affects one s conclusions about affirmative action further even in some cases where segregation has eliminated discriminatory wage differentials the introduction of affirmative action has allocative effects finally evidence from studies evaluating the impact of affirmative action is used to distinguish among the various equilibrium models

employment and technological innovation evidence from u k manufacturing firms this article uses british firm level panel data on actual innovative activity drawn from different statistical sources to identify the effect of technical change on jobs previous work tends to find positive associations of proxies for technical change and employment but such studies suffer from various statistical drawbacks in this study even when one controls for fixed effects dynamics and endogeneity innovations have a positive and significant effect on employment which persists over several years there seems to be little direct role for spillover effects from industry innovations or any role for industry wages or union power

the spatial mismatch hypothesis what has the evidence shown this paper reviews 20 years worth of empirical evidence on the spatial mismatch hypothesis after briefly surveying the relevant models from urban and labour economics and recent trends in employment and population suburbanisation the empirical evidence on spatial effects is examined this literature includes evidence on the effects of residential segregation residential suburbanisation and employment suburbanisation and direct measures of access such as travel times the most recent evidence suggests that spatial mismatch is relevant for explaining black white employment differences though the magnitudes of these effects remain unclear

search method use by unemployed youth this article presents a search model which shows that search method choices should be related to their costs and expected productivities as well as to nonwage income and wage offer distributions the empirical evidence then shows that the most frequently used search methods i e friends and relatives and direct applications without referral are also the most productive in generating offers and acceptances the number of methods used is affected by factors that presumably reflect opportunities as well as income sources and needs specific methods are chosen in a manner that generates positive average effects on outcomes for those using them

consumer discrimination and self employment self employment rates and incomes differ significantly by race we show that these differentials arise in markets with consumer discrimination and incomplete information about the price of the good and the race of the seller equilibrium income distributions have two properties mean black incomes are lower than mean white incomes and the returns to ability are lower for black than for white sellers able blacks therefore are less likely to self select into the self employment sector than able whites using the 1980 census data we find that observed racial differences in the self employment income distributions are consistent with the theoretical predictions

city structure job search and labour discrimination theory and policy implications we consider a search matching model in which black workers are discriminated against and the job arrival rates of all workers depend on social networks as well as distance to jobs location choices are driven by the racial preferences of households both blacks and whites consciously choosing to trade off proximity to neighbors of similar racial backgrounds for proximity to jobs because of coordination failures in the location choices multiple urban equilibria emerge there is a spatial mismatch equilibrium in which blacks reside far away from jobs and experience high unemployment rates and a spatial match equilibrium in which blacks are closer to jobs and experience lower unemployment rates under some reasonable condition we demonstrate that all workers are better off in the spatial match equilibrium we then consider two policies affirmative action and employment subsidies to the firms which hire black workers we show that the optimal policy requires imposing larger quotas or subsidies in cities in which black workers reside far away from jobs than in cities in which they live closer to jobs
