To examine how human capital accumulation influences both economic growth and income quality, we carefully endogenize the demand and supply of skills. We explicitly introduce the costs and externalities in education, and examine how both relate to learning-by-doing and R&D intensity. In...

This paper examines how the accumulation of human capital determines both a country's growth rate and income inequality. In contrast to previous work, we do not rely on credit market imperfections or political economy arguments. The insight of this model is that inequality is determined by the...

We develop an assignment model of automation. Each of a continuum of tasks of variable complexity is assigned to either capital or one of a continuum of labor skills. We characterize conditions for interior automation, whereby tasks of intermediate complexity are assigned to capital. Interior...
