This paper examines how human capital based approaches explain the distribution of earnings. It assesses traditional, quasi-experimental, and new micro-based structural models, the latter of which gets at population heterogeneity by estimating individual-specific earnings function parameters....

A pre-condition for employer learning is that signals at labor market entry do not fully reveal graduates' productivity. I model various distinct sources of signal imperfection - such as noise and multi-dimensional types - and characterize their implications for the private return to skill...

This paper studies optimal taxation of income and education when employers cannot observe workers' productivity and workers signal their productivity to firms by choosing both quantity and quality of education. We characterize constrained efficient allocations and derive conditions under which...

We examine how informational frictions impact schooling and work outcomes. To do so, we estimate a dynamic structural model where individuals face uncertainty about their academic ability and productivity, which respectively determine their schooling utility and wages. Our framework accounts for...
