Migration, Search and Skill Heterogeneity

No 2023/136, IMF Working Papers from International Monetary Fund

Abstract: Cross-border migration can act as an important adjustment mechanism to country-specific shocks. Yet, depending on who moves, it can have unintended consequences for business cycle stability. This paper argues that the skill composition of migration plays a critical role. When migration flows become more concentrated in skilled labor an important trade-off arises. On the one hand, migration releases unemployment pressures for the origin countries. On the other hand, it generates negative compositional effects (the so-called “brain drain” effects) and skill imbalances, which reduce supply capacity in origin countries. This paper analyses quantitatively the impact of cyclical migration in an open-economy Dynamic Stochastic General Equilibrium (DSGE) model with endogenous migration flows, trade linkages, search and matching frictions, and skill heterogeneity. I apply this framework to the case of the Greek emigration wave following the European Debt Crisis. What I find is that emigration flows implied strong negative effects for capital formation, leading to more than a 15 percentage point drop in investment. Rather than stabilizing the Greek business cycle, labor mobility led to a deeper and more protracted recession.
