Under the standard competitive model, a tax change affecting workers with highly inelastic labor supply, will lower earnings by the entire nominal employer share of the tax increase. If wages play a motivational role but the market still clears, the range of possible outcomes is broader but...

Almost all labor supply models are estimated under the assumption that workers are free to choose their hours. However, theory, casual empiricism and survey data suggest that many workers are not free to vary the hours within a job. Consequently, labor supply estimates based on actual hours of...

African Americans face shorter employment durations than apparently similar whites. We hypothesize that employers discriminate in either acquiring or acting on ability-relevant information. We construct a model in which firms may "monitor" workers. Monitoring black but not white workers is...

Among college graduates, teachers have both low average AFQT and high average risk aversion, perhaps because the compression of earnings within teaching attracts relatively risk-averse individuals. Using a dynamic optimization model with unobserved heterogeneity, we show that were it possible to...

The street sex worker market in Geylang, Singapore is highly competitive. Clients can search legally at negligible cost. Sex workers discriminate based on client ethnicity despite an excess supply of sex workers. Workers are more (less) likely to approach and ask a higher (lower) price of...

Some economists have argued that assortative mating between men and women has increased over the last several decades, thereby contributing to increased family income inequality. Sociologists have argued that educational homogamy has increased. We clarify the relation between the two and, using...

We show that in labor market models with adverse selection, otherwise observationally equivalent workers will experience less wage growth following a period in which they change jobs than following a period in which they do not. We find little or no evidence to support this prediction. In most...
