The strategic bombing of German cities during WWI and its impact on city growth

Abstract

We construct a unique data set in order to analyze whether or not a large temporary shock has an impact on city growth. Following recent work by Davis and Weinstein (2002) on Japan, we take the strategic bombing of German cities during WWII as an example of such a shock, and analyze its impact on post-war German city growth. If the war shock has only a temporary impact, then there will be a tendency towards mean reversion. Our main finding is that the bombing had a significant but temporary impact on post-war city growth in Germany as a whole as well as in western Germany separately (FRG), but that this is not the case for city growth in eastern Germany (GDR).
