Bahar, D., A Hauptman, C Ozguzel and H Rapoport. "Migration and post-conflict reconstruction: The effect of returning refugees on export performance in the former Yugoslavia"

Elevator pitch: During the early 1990s over 500 thousand refugees from Yugoslavia settled in Germany. A few years later, after the 1995 peace treaties were signed, most of them were repatriated back. We find that the industries that perform best in the Yugoslavian countries post-1995 were the ones for which returning refugees worked in while in Germany. The effect is driven by refugees in occupations with managerial characteristics.Latest online version: IZA Media and commentary: VoxDev, VoxEU
