Title: The Long-Run Effects of Immigration: Evidence Across a Barrier to Refugee Settlement
Abstract: We identify the causal effect of immigration on productivity, wages, incomes, and rents in the long run using a spatial regression discontinuity design (RDD). Our spatial RDD builds on a short-lived barrier to refugee settlement within West Germany after WWII. Comparing municipalities in a narrow band around this barrier, we find no socio-economic differences before WWII. In particular, population density had always been identical. But when the barrier to refugee settlement was removed, population density was about 20 percentage points higher where refugees had been allowed to settle. In 2020, 70 years later, the higher population density still persists. Today’s higher density coincides with higher productivity, wages, and rents. We argue that these economic differences are the result of agglomeration economies driven by the higher population density where refugees had been allowed settle. We present evidence on the nature of these agglomeration economies.
