My work concentrates on determinants of labour earnings and is intensely empirical. Early work on returns to schooling was followed by a prolonged series on group differences in earnings. Several compare blacks and whites and one contrasts Hispanics and Anglos.
Much of the work is descriptive, characterising patterns and the evolution of group differences through time. The behavioural work, in the context of competitive markets, concentrates on determinants of major swings in earnings patterns. Income differences by age, schooling level, and race are examined for responses to changes in labour force composition and protective legislation.
Analysis of effects of cohort size on age-learning profiles traces early results and future implications for the baby boom cohorts. Effects of rising education levels are contrasted with growth in labour productivity and cyclical swings in tracing changes in patterns of income differences by schooling. Currently involved with implications of modern and discriminatory legislation, together with its enforcement apparatus, and the comparison of evolving patterns of income and employment differences between those protected and those not protected by the legislation.
