Zusammenfassung:
International immigration flows are large, volatile and have recently increased. This paper is the first to study the dynamic effects of immigration shocks on the economy within a search and matching framework. Since the microdata indicates that some of the key macroeconomic effects of immigration are largest in the short run, a steady state analysis would be insufficient. To construct a quantitatively relevant general equilibrium framework, we use extensive Swedish microdata. We then study the effect of a large immigration shock on various macroeconomic aggregates. Due to compositional effects, there is a substantial negative effect on GDP per capita and the employment rate on impact that then decreases over time.
