This study evaluates the impact of high-skilled immigrants on U.S. technology formation. We use reduced-form specifications that exploit large changes in the H-1B visa program. Higher H-1B admissions increase immigrant science and engineering (SE) employment and patenting by inventors with Indian and Chinese names in cities and firms dependent upon the program relative to their peers. Most specifications find limited effects for native SE employment or patenting. We are able to rule out displacement effects, and small crowding-in effects may exist. Total SE employment and invention increases with higher admissions primarily through direct contributions of immigrants.

This article studies interfirm racial segregation in two newly developed firm‐level databases. We find that the interfirm distribution of black and white workers is close to what would be implied by random assignment. We also find that black workers are clustered in employers where managers, owners, and customers are also black. These findings may be reconciled by the facts that (a) there are not enough black employers to generate much segregation and that (b) other forces may systematically integrate black and white workers. Finally, we find that the black/white wage gap is primarily a within‐firm phenomenon.

The Immigration Reform and Control Act of 1986 (IRCA) represents an attempt to use labor market regulation to control illegal migration into the United States by imposing fines on employers who hire unauthorized workers. Sanctions lower wages directly because they act as a tax on hiring additional workers. In addition, IRCA legalized many longtime illegal aliens. Legalization affects wages by changing the relative supply of authorized and unauthorized workers. This study estimates IRCA's impact on wages of manufacturing production workers in metropolitan areas and finds small but statistically significant effects: sanctions lower wages, while legalization raises them.

Broiler chickens are raised by contract growers whose rewards depend explicitly upon relative performance. The authors use data on the performance of broiler producers facing both tournament and linear performance evaluation compensation structures to test three predictions from the theory of tournaments: that changes in the level of prizes that leave prize differentials unchanged will not affect performance; that, in mixed tournaments, more able players will choose less risky strategies; and that tournament organizers will attempt to handicap players of unequal ability or reduce mixing to avoid the disincentive effects of mixed tournaments. Their evidence is consistent with each prediction.

This article examines the resource allocations of parents in the form of both shared residence with and financial transfers to their young adult sons. Based on an overlapping generations model incorporating a game between parents and adult children, estimates of the determinants of such transfers are obtained from the kinship-linked cohorts of the National Longitudinal Surveys. The estimates suggest that both types of parental assistance are as important as governmental transfers in supporting young men and are responsive to the current and anticipated earnings of their offspring, suggesting that young men cannot adequately smooth their consumption without parental help.

A new data set covers chief executive officers (CEOs) of large commercial banks over the period 1982-87. For newly hired CEOs, the elasticity of pay with respect to assets is about one-third. For continuing CEOs, the change in compensation depends on performance, as measured by stock and accounting returns. The sensitivity of pay to performance diminishes with experience, but the returns are not filtered for peer-group returns. Logit regressions relate the probability of CEO departure to age and performance, as measured by stock returns filtered for peer-group returns; CEO experience does not influence this relationship.

We use admissions lotteries to estimate the effects of attendance at Boston's charter high schools on college preparation, college attendance, and college choice. Charter attendance increases pass rates on the high-stakes exam required for high school graduation in Massachusetts, with especially large effects on the likelihood of qualifying for a state-sponsored college scholarship. Charter attendance has little effect on the likelihood of taking the SAT, but shifts the distribution of scores rightward, moving students into higher quartiles of the state SAT score distribution. Boston's charter high schools also increase the likelihood of taking an Advanced Placement (AP) exam, the number of AP exams taken, and scores on AP Calculus tests. Finally, charter attendance induces a substantial shift from two-to four-year institutions, though the effect on overall college enrollment is modest. The increase in four-year enrollment is concentrated among four-year public institutions in Massachusetts. The large gains generated by Boston's charter high schools are unlikely to be generated by changes in peer composition or other peer effects.

How do alternative job opportunities affect teacher quality? We provide causal evidence on this question by exploiting business cycle conditions at career start as a source of exogenous variation in the outside options of potential teachers. Unlike prior research, we directly assess teacher quality with value-added measures of impacts on student test scores, using administrative data on over 30,000 Florida public school teachers. Consistent with a Roy model of occupational choice, teachers entering the profession during recessions are significantly more effective in raising student test scores. Results are supported by robustness tests and unlikely to be driven by differential attrition.
