Effects of personal and school characteristics on estimates of the return to education

What is the economic return to attending college? The earnings gap between college and high school graduates is large, but college and high school graduates differ in many ways besides education. This article finds that differences in family background and ability explain about one fourth of the gap.Education ; Employees, Training of

The marginal propensity to spend on adult children

We examine how much of an extra dollar of parental lifetime resources will ultimately be passed on to adult children in the form of inter vivos transfers and bequests. We infer bequests from the stock of wealth late in life. We use mortality rates and age specific estimates of the response of transfers and wealth to permanent income to compute the expected present discounted values of these responses to permanent income. Our estimates imply parents pass on between 2 and 3 cents out of an extra dollar of expected lifetime resources in bequests and about 2 cents in transfers. The estimates increase with parental income and are smaller for nonwhites. They imply that about 15 percent of the effect of parental income on lifetime resources of adult children is through transfers and bequests and about 85 percent is through the intergenerational correlation in earnings, although these estimates are sensitive to assumptions about the intergenerational earnings correlation, taxes, and the number of children. We compare our estimates to the implications of alternative computable benchmark models of savings behavior in order to assess the likely importance of intended bequests for the wealth/income relationship.Bequests, intervivos transfers, permanent income

Group-Average Observables as Controls for Sorting on Unobservables When Estimating Group Treatment Effects: The Case of School and Neighborhood Effects

We consider the classic problem of estimating group treatment effects when individuals sort based on observed and unobserved characteristics. Using a standard choice model, we show that controlling for group averages of observed individual characteristics potentially absorbs all the across-group variation in unobservable individual characteristics. We use this insight to bound the treatment effect variance of school systems and associated neighborhoods for various outcomes. Across four datasets, our conservative estimates indicate that a 90th versus 10th percentile school system increases high school graduation and college enrollment probabilities by at least 0.047 and 0.11. Other applications include measurement of teacher value-added

The Effects of Immigration on the Labor Market Outcomes of Natives

This paper examines the effects of immigration on the labor market outcomes of less-skilled natives. Working from a simple model of a local labor market, we show that the effects of immigration can be estimated from the correlations between the fraction of immigrants in a city and the employment and wage outcomes of natives. The size of the effects depend on the fraction and skill composition of the immigrants. We go on to compute these correlations using city-specific outcomes for individuals in 120 major SMSA's in the 1970 and 1980 Censuses. We also use the relative industry distributions of immigrants and natives to provide a direct assessment of the degree of labor market competition between them. Our empirical findings indicate a modest degree of competition between immigrants and less-skilled natives. A comparison of industry distributions shows that an increase in the fraction of immigrants in the labor force translates to an approximately equivalent percentage increase in the supply of labor to industries in which less-skilled natives are employed. Based on this calculation, immigrant influws between 1970 and 1980 generated 1-2 percent increases in labor supply to these industries in most cities. A comparison of industry distributions of less-skilled natives in high- and low-immigrant share cities between 1970 and 1980 shows some displacement out of low-wage immigrant-intensive industries. We find little effect of immigration on the employment outcomes of the four race/sex groups that we consider. Our estimates of the effect of immigration on the wages of less-skilled natives are sensitive to the specification and estimation procedure. However, our preferred estimates, which are based on first differences between 1980 and 1970 and the use of instrumental variables to control for the endogeneity of immigrant inflows, imply that an increase in immigrants equal to 1 percent of an SMSA's population reduces native wages by roughly 1.2 percent.

Vacation laws and annual work hours

This article reviews the theory and evidence regarding how work hours are determined and the role of employer policies on vacation. The authors discuss possible economic rationales for vacation laws and present empirical evidence on whether they affect annual work hours. The results indicate that vacation laws lead to a substantial reduction in work hours.Hours of labor ; Vacations, Employee

Testing the Response of Consumption to Income Changes with (Noisy) PanelData

This paper tests the rational expectations lifecycle model of consumption against (1) a simple Keynesian model and (ii) the rational expectations lifecycle model with imperfect capital markets. The tests are based upon the relative responsiveness of consumption to income changes which can be predicted from past information and income changes which cannot be predicted. Since there is strong evidence that panel data contains substantial measurement error, the tests are especially constructed to allow for measurement error in the income process. They also allow for more general income processes than have been considered to date in the literature. The results reject the Keynesian model and generally support the lifecycle model, although the tests are not sufficiently precise to rule out the possibility that some households are liquidity constrained. Measurement error does have a strong influence on the relationship between consumption and income. When it is ignored our tests do not reject the Keynesian model. We show that consideration of measurement error may also reconcile differences in the results of Hall and Mishkin (1982) and Bernanke(1984). Nevertheless, our most important conclusion is that Hall and Mishkin's, Bernanke's, and Hayashi's (198 ) qualitative finding that the vast majority of households obey the lifecycle model is not an artifact of failure to account for measurement error in the income data.

The Role of Permanent Income and Demographics in Black/White Differences in Wealth

We explore the extent to which the huge race gap in wealth can be explained with properly constructed income and demographic variables. In some instances we explain the entire wealth gap with income and demographics provided that we estimate the wealth model on a sample of whites. However, we typically explain a much smaller fraction when we estimate the wealth model on a black sample. Using sibling comparisons to control for intergenerational transfers and the effects of adverse history, we find that differences in income and demographics are not likely to account for the lower explanatory power of the black wealth models. Our analysis of growth models of wealth suggests that differences in savings behavior and/or rates of return play an important role.Black-White Wealth Gap, Siblings, Savings

Work Hours, Wages, and Vacation Leave

Using the Panel Study of Income Dynamics and the Health and Retirement Study, we provide a set of facts about vacation leave and its relationship to hours worked, hours constraints, wage rates, worker characteristics, spouse's vacation leave, labor market experience, job tenure, occupation, industry, and labor market conditions. We show that on average vacation time taken rises 1 to 1 with paid vacation but varies around it, that annual hours worked fall by about 1 full time week with every week of paid vacation, that the gap between time taken and time paid for is higher for women, union members, and government workers, that hourly wage rates have a strong positive relationship with paid vacation weeks both in the cross section and across jobs, and that nonwage compensation is positively related to vacation weeks. We provide evidence that vacation leave is determined by broad employer policy rather than by negotiation between the worker and firm. In particular, it is strongly related to job seniority but depends very little on labor market experience, and for job changers it is only weakly related to the amount of vacation on the previous job.

Job Characteristics and Hours of Work

This paper provides evidence that hours of work are heavily influenced by the particular job which a person holds. The empirical work consists of a comparison of the variance in the change in work hours across time intervals containing a job change with the variance in the change in hours across time periods when the job remains the same. To the extent that workers choose hours and these hours choices are influenced by shifts in individual preferences and resources, the variance in the time change of hours should not depend upon whether the worker has switched jobs. The desire to reduce or increase hours could be acted upon in the current job. On the other hand, if hours are influenced by employer preferences or if job specific characteristics dominate the labor supply decision, then hours changes should be larger when persons change jobs than when they do not. Using the Panel Study of Income Dynamics and the Quality of Employment Survey, we find that hours changes are typically two to four times more variable across jobs than within jobs. This result holds for both men and women and for both quits and layoffs, is obtained for weeks per year, hours per week, and annual hours, andis not sensitive to the use of controls for a set of job characteristics (including the wage) which might influence the level of hours persons wish to supply. The findings are also inconsistent with the view that workers may costlessly adjust hours by changing jobs.The finding that the job has a large influence on work hours suggests that much greater emphasis should be given to demand factors and to job specific labor supply factors in future research on hours of work. The overwhelming emphasis upon the wage and personal characteristics inconventional labor supply analyses of work hours may in part be misplaced.
