We attempt to further characterize the search strategies of the employer. In the article, we discuss how characteristics of the employer or conditions that the employer faces affect the optimal search strategies and the probability of filling a vacancy in each period. Semiparametric and parametric methods are used to estimate hazard rates of filling vacancies. The results suggest that for the given sample of vacancies, the general form of the hazard function is nonmonotonic. Additionally, the results suggest that those employers who have advance notice of the vacancy may search longer than those employers who do not.

This article reexamines the negative seniority‐earnings relationship for academic economists. The empirical results show that the anomalous negative seniority effect found in earlier academic market studies holds in the absence of direct measures of research productivity. The negative effect, however, eventually disappears as more comprehensive measures of publishing, citations, and other productivity measures are included in the wage equation to control for the quantity and quality of faculty productivity. Faculty with greater seniority appear to be rewarded relatively less simply because many have been relatively less productive than their colleagues with less seniority at similar stages in their careers.

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 proportion of women in state government jobs and applicant pools is well explained by a model emphasizing supply‐side factors. Relative to men, women's supply is least sensitive to wages in predominantly male jobs and most sensitive to wages in predominantly female jobs. These results suggest that comparable worth policies that shift relative pay toward traditionally female jobs and away from traditionally male jobs will increase the proportion of females in male‐dominated, female‐dominated, and total state government jobs. The implication is that supply side responses need not prevent comparable worth pay adjustments from raising total female compensation.

This article uses various micro data sets to study entrepreneurship. Consistent with the existence of capital constraints on potential entrepreneurs, the estimates imply that the probability of self-employment depends positively upon whether the individual ever received an inheritance or gift. When directly questioned in interview surveys, potential entrepreneurs say that raising capital is their principal problem. Consistent with our theoretical model's predictions, the self-employed report higher levels of job and life satisfaction than employees. Childhood psychological test scores, however, are not strongly correlated with later self-employment.
