Abstract: 
The unification of the East and West German states in 1990 initiated the integration of two distinct innovation systems. In this process, the poorly functioning socialist system of East Germany adopted the formal institutions and organization of West Germany, a western-style market economy. We investigate the effect of this integration on patenting activity by applying a difference-in-difference approach. While patenting activity increased in both parts of the country until recently, the gap between East and West Germany widened considerably over time. This divergence in innovation activity suggests that current East-West differences may be indirectly rooted in this socialist legacy and the sudden shock transformation that occurred upon reunification. We also find that the similarity of the technology profile of the East and West German innovation systems is crucial to understand the divergence. So, East German innovation activity fell behind especially in technologies where both East and West Germany were specialized in before re-unification. The same applies to technologies where only West Germany was specialized in. Our findings indicate that integrating the two innovation systems mainly benefitted the West.
