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...

The empirical literature on employer learning assumes that employers learn about unobserved ability differences across workers as they spend time in the labor market. This article describes testable implications that arise from this basic hypothesis and how they have been used to quantify the...

This paper surveys the theoretical approaches used in the literature to study the phenomenon of delayed graduation and university dropout. The classical human capital model does not contemplate failure, which the amended human capital model does. Delayed graduation and university dropout are two...

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...
