The Intergenerational Mobility of Immigrants

This paper analyzes the intergenerational mobility of immigrants. Using the 1940-1970 Censuses, the study reveals an important link between the earnings of immigrants and the earnings of their American-born children. Although there is some regression towards the mean, the earnings of second-generation Americans are strongly affected by variables describing economic conditions in the source countries of their parents. Current immigration policy, therefore, determines not only how immigrants perform in the labor market, but also determines tomorrow's differences in the labor market experiences of American-born ethnic groups.

The Sensitivity of Labor Demand Functions to Choice of Dependent Variable

This paper investigates whether the parameters of labor demand functions are sensitive to alternative methods of estimation. The assumption that the production technology is of the Generalized Leontief type implies that the demand system can be estimated by analyzing cross-section differences in earnings across labor markets, by studying longitudinal changes in earnings within a labor market, or by investigating cross-section differences in labor force participation rates across labor markets. The estimation of these models on the 1970 and 1980 Public Use Samples from the U.S. Census reveals that the estimates of labor demand functions are indeed quite robust to major specification changes.

Welfare Reform, Labor Supply, and Health Insurance in the Immigrant Population

Although the 1996 welfare reform legislation limited the eligibility of immigrant households to receive assistance, many states chose to protect their immigrant populations by offering state-funded aid to these groups. I exploit these changes in eligibility rules to examine the link between the welfare cutbacks and health insurance coverage in the immigrant population. The data reveal that the cutbacks in the Medicaid program did not reduce health insurance coverage rates among targeted immigrants. The immigrants responded by increasing their labor supply, thereby raising the probability of being covered by employer-sponsored health insurance.

Do Foreign Students Crowd Out Native Students from Graduate Programs?

This paper examines how the growth in the number of foreign students enrolled in graduate programs affects native enrollment in those programs. Although there is little evidence of a crowdout effect for the typical native student, the impact of foreign students on native educational outcomes differs dramatically across ethnic groups, and is particularly adverse for white native men. There is a strong negative correlation between increases in the number of foreign students enrolled at a particular university and the number of white native men in that university's graduate program. This crowdout effect is strongest at the most elite institutions.
