Self-Reported vs. Objective Measures of Health in Retirement Models

Labor supply estimates are sensitive to the measures of health used. When self reported measures are used health seems to playa larger role and economic factors a smaller one than when more objective measures are used" While most authors have interpreted these results as an indication of the biases inherent in using self-reported measures, there are reasons to be suspicious of estimates based on more objective measures as well. In this paper I construct a statistical model incorporating both self-reported and objective measures of health. I use the model to show the potential biases involved in using either measure of health or in using one to instrument the other- When outside information on the validity of self-reported measures of health are incorporated into the model estimates suggest that the self-reported measures of health perform better than many have believed.

Cohort Crowding: How Resources Affect Collegiate Attainment

Analyses of college attainment typically focus on factors affecting enrollment demand, including the financial attractiveness of a college education and the availability of financial aid, while implicitly assuming that resources available per student on the supply side of the market are elastically supplied. The higher education market in the United States is dominated by public and non-profit production, and colleges and universities receive considerable subsidies from state, federal, and private sources. Because consumers pay only a fraction of the cost of production, changes in demand are unlikely to be accommodated fully by colleges and universities without commensurate increases in non-tuition revenue. For this reason, public investment in higher education plays a crucial role in determining the degrees produced and the supply of college-educated workers to the labor market. Using data covering the last half of the twentieth century, we find strong evidence that large cohorts within states have relatively low undergraduate degree attainment, reflecting less than perfect elasticity of supply in the higher education market. That large cohorts receive lower public subsidies per student in higher education explains this result, indicating that resources have large effects on degree production. Our results suggest that reduced resources per student following from rising cohort size and lower state expenditures are likely to have significant negative effects on the supply of college-educated workers entering the labor market.

What are the causes of rising wage inequality in the United States?

During the last 15 years--especially in the 1980s--wage inequality rose in the United States. It appears that this can be explained by a secular shift in production functions favoring workers with intellectual rather than manual skills, together with slower growth in the supply of skilled labor than in the previous decade.Education ; Labor supply ; Wages ; Income distribution

The Social Security Early Retirement Benefit as Safety Net

In this paper we used the Health and Retirement Study to examine the health and economic status of those who collect Social Security retirement benefits prior to the full retirement age. We used a propensity score reweighting method to estimate the fraction of early retirees who use early retirement benefits as a safety net against deteriorating health and who might be induced to apply for disability benefits (SSDI) or retire without income replacement if the generosity or availability of early retirement benefits were reduced. We find that while the majority of early retirees would likely not qualify for disability benefits, approximately one in five have health characteristics similar to SSDI beneficiaries, and thus might not be able to replace losses in benefit income with labor income.

Estimating the Health Effects of Retirements

We estimate the magnitude of any direct effect of retirement on health. Since retirement is endogenous to heath, it is not possible to estimate this effect by comparing the health of individuals before and after they retire. As an alternative we use institutional features of the pension system in the United Kingdom that are exogenous to the individual to isolate exogenous variation in retirement behavior. Data used will include both vital statistics and survey data that include both "objective" physical measurements and respondent self-reports. We find no evidence of negative health effects of retirement and some evidence that there may be a positive effect, at least for men.

Closing the Gap or Widening the Divide: The Effects of the G.I. Bill and World War II on the Educational Outcomes of Black Americans

The effects of the G.I. Bill on collegiate attainment may have differed for black and white Americans owing to differential returns to education and differences in opportunities at colleges and universities, with men in the South facing explicitly segregated colleges. The empirical evidence suggests that World War II and the availability of G.I. benefits had a substantial and positive impact on the educational attainment of white men and black men born outside the South. However, for those black veterans likely to be limited to the South in their educational choices, the G.I. Bill had little effect on collegiate outcomes, resulting in the exacerbation of the educational differences between black and white men from southern states.

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-l970s through the 1980s that differs among subgroups. Earnings gaps increased most among college graduates and in the midwest while gaps in employment-population rates grew most among high school dropouts. We attribute the differential widening to distinct shifts in demand for subgroups due to changes in industry and regional employment, the falling real minimum wage and deunionisation, the growth of the relative supply of black to white workers that was marked among college graduates, and to increased crime, that was marked among high school dropouts. The differential factors affecting the groups highlights the economic diversity of black Americans.

Changes in the Structure of Wages During the 1980's: An Evaluation of Alternative Explanations

Between 1979 and 1987 there were three significant changes in the wage structure in the United States. the pecuniary returns to schooling increased by about a third; the wages of older relative to younger workers with relatively low education increased to some extent; and the wages of women relative to men rose by almost ten percent. It is important for policy purposes to know why these changes occurred and whether they are temporary or permanent. The paper investigates several alternative explanations of these wage structure phenomena, including the most popular ones that their principal causes were shifts in the structure of product demand, skilled-labor saving technological change, and changes in the incidence and level of rents received by lower skilled workers. our reading of the evidence suggests that the major cause of the dramatic movements in the wage structure during the 1980's may have been some combination of changes in both production technology and the average relative nonobserved quality of different labor groups.
