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...

This study investigates the dynamics of between-group and within-group wage inequality in a model with heterogeneous learning abilities putting a key emphasis on the shape of the ability distribution. In our model, intergenerational human capital externalities incentivize individuals to invest...

While there is a wealth of literature dealing with the spatial nature of knowledge and its transferral, I argue that the underlying mechanisms have not been sufficiently understood. Existing research relating the geography of inflows to firm productivity does not adequately address firm and...
