We use twenty years of Italian administrative panel data, a uniquely rich source of information on internal migration experiences, to identify the role of unobserved worker characteristics in the selection and returns to migrants. We propose and implement a novel iterative estimation method for...

We propose a simple test that uses information on workers’ mobility, wages and firms’ profits to identify the sign and strength of assortative matching. The basic intuition underlying our empirical strategy is that, in the presence of positive (negative) assortative matching, good workers...

We present a partnership model where heterogeneous agents bargain over the gains from trade and search on the match. Frictions allow agents to extract higher rents from more productive partners, generating an endogenous preference for high types. More productive agents upgrade their partners...
