This paper develops and estimates a human capital model of wage growth based on learning by doing. Learning by doing rates are assumed to be heterogeneous and firms offer different career structures in terms of the rate of acquisition of firm specific human capital. The model is estimated using...

This paper surveys recent work in equilibrium models of labor markets characterized by search and recruitment frictions and by the need to reallocate workers across productive activities. The duration of unemployment and jobs and wage determination are treated as endogenous outcomes of job...

The spatial dispersion of economic agents is an immediate determinant of informational imperfections. We investigate how this dispersion creates search frictions and thus rationing. For that, we develop a model of local labour markets in which workers' search efficiency is negatively affected by...

This paper presents a model in which firms and workers must engage in costly search to find a production partner. In this setting the skill, job and wage distributions and their evolutions are endogenized. The presence of search frictions implies that there are two redistributive forces in the...

We compare the performance of markets and tournaments as allocative mechanisms in an economy with borrowing constraints. The model consists of a continuum of individuals who differ in their initial wealth and ability level (e.g. students) and that are to be assigned to a continuum of investment...
