OxTalks is Changing
On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Migration, Search and Skill Heterogeneity
This paper studies the impact of migration over the business cycle focusing on origin countries. According to conventional wisdom, cross-border labour mobility acts as an important adjustment mechanism during recessions; it is a way to reduce unemployment pressures and to smooth consumption via remittances. I argue that there is an important factor that previous research on cyclical migration has overlooked: skill heterogeneity. With recent migration flows becoming increasingly more concentrated in skilled labour an important trade-off arises. On the one hand, migration releases unemployment pressures and it creates beneficial risk-sharing channels for the origin countries. On the other hand, it generates negative compositional effects (the so called “brain-drain” effects) and skill imbalances which deepen and prolong rather than dampen recessions in the origin countries. I analyse quantitatively the impact of cyclical migration in an open-economy 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. I find that emigration flows imply negative dynamic effects for capital formation. Rather than stabilising the Greek business cycle, labour mobility had a destabilising effect leading to a deeper and more protracted recession.
