We develop a model of the structural transformation with three sectors: agriculture, industry, and services. In addition to reallocation across sectors over time, the model also features a reallocation of consumption across services that differ in their labor intensity and a distribution sector....

Consider the following facts. In 1950 rich countries attained an average of 8.1 years of schooling whereas poor countries attained 1.3 years --a 6-fold difference. By 2005, the difference in schooling declined to 2-fold even though the per-capita income gap did not decrease. What explains...

We analyze the forces that can generate retirement in different versions of standard life cycle models of labor supply. While nonconvexities in production can generate retirement, we show that the size of nonconvexities needed increases sharply as the intertemporal elasticity of substitution for...

This paper analyzes a business cycle model with labor market frictions as well as an extensive labor supply margin. There are exogenous aggregate shocks to productivity, the job finding rate, and the separation rate. Workers also face idiosyncratic productivity (wage) shocks that they cannot...
