Innovation cooperation in East Germany - only a half-way success?

The paper focuses on the question whether enterprises that engage in innovation cooperation with external partners are more innovative and thus more productive than non-cooperating firms. A comparison between East and West Germany is being made. It shows that cooperating enterprises in East and West Germany are indeed more innovative than non-cooperating firms, but there remains a clear productivity gap between East and West German cooperating firms. Furthermore, in East Germany - different from West Germany - non-cooperating firms are even more productive than cooperating firms.
