We examine the impact of immigration on innovation by exploiting a placement policy for immigrants in Germany. This allows us to overcome the potential bias of endogenous location decisions. Although the majority of inflows was unskilled, we do not find any evidence of a negative impact on innovations. Instead, our panel estimates suggest that immigration had no or even a positive impact on innovations.
