We use a novel dataset and research design to empirically detect the effect of social interactions among neighbors on labor market outcomes. Specifically, using Census data that characterize residential and employment locations down to the city block, we examine whether individuals residing in...

Cooper and Willis (2003) is the latest in a sequence of criticisms of our methodology for estimating aggregate nonlinearities when microeconomic adjustment is lumpy. Their case is based on 'reproducing' our main findings using artificial data generated by a model where microeconomic agents face...

This paper analyzes the influence that juvenile offenders serving time in the same correctional facility have on each other's subsequent criminal behavior. The analysis is based on data on over 8,000 individuals serving time in 169 juvenile correctional facilities during a two-year period in...

We use a model of human capital investment and activity choice to explain facts describing gender differentials in the levels and returns to human capital investments. These include the higher return to and level of schooling, the small effect of healthiness on wages, and the large effect of...

It is often argued that informal labor markets in developing countries promote growth by reducing the impact of regulation. On the other hand informality may reduce the amount of social protection offered to workers. We extend the wage-posting framework of Burdett and Mortensen (1998) to allow...

We examine the generalizability of internally valid estimates of causal effects in a fixed population over time when that population is subject to aggregate shocks. This temporal external validity is shown to depend upon the distribution of the aggregate shocks and the interaction between these...

Despite the lower quality of education provided Africans compared with whites in South Africa, the percentage wage gains associated with additional years of primary, secondary, and higher education are substantially larger for Africans than for whites in 1993, and they increase for both race...

This research examines differences in earnings structure between Communist and post-Communist Czech Republic and Slovakia using four sets of similar micro-data. It presents hypotheses about how earnings dispersion returns to education and returns to experience will change across regimes and...

We estimate the effects of higher quality healthcare usage on health, labor supply and schooling outcomes for sick individuals in Tanzania. Using exogenous variation in the cost of formal sector healthcare to predict treatment choice, we show that using better quality care improves health...
