Based on a large employer-employee matched dataset, the Paper investigates the effects of variable enforcement of German dismissal protection legislation on the employment dynamics in small establishments. Specifically, using a difference-in-differences approach, we study the effect of changes...

Empirical studies in the migration literature have shown that migration enclaves (networks) negatively affect the language proficiency of migrants. These studies, however, ignore the choice of location as a function of language skills. Using data on Mexican migration to the US, we show that...

This Paper addresses the question: why and where do immigrants cluster? We examine the relative importance and interaction of two alternative explanations of immigrant clustering: (1) network externalities and (2) herd behavior. We advance the theory by presenting a framework encompassing both...

The Paper examines real and nominal wage rigidities. We estimate a switching regime model, in which the observed distribution of individual wage changes, computed from West German register data for 1976-97, is generated by simultaneous processes of real, nominal or no wage rigidity, and...

This article examines real and nominal wage rigidities in West Germany. Using regionally disaggregated register data for 1975-2001, we estimate the extent of both types of wage rigidities from the observed distribution of individual wage changes, taking into account possible measurement error....
