New publication on Joint R&D subsidies, related variety, and regional innovation

The paper, „Joint R and D subsidies, related variety, and regional innovation“, has been published in International Regional Science Review. The paper is co-authored by Matthias Brachert, Matthias Duschl, and Thomas Brenner.


Subsidies for R&D are an important tool of public R&D policy, which motivates extensive scientific analyses and evaluations. The paper adds to this literature by arguing that the effects of R&D subsidies go beyond the extension of organizations’ monetary resources invested into R&D. It is argued that collaboration induced by subsidized joint R&D projects yield significant effects that are missed in traditional analyses.An empirical study on the level of German labor market regions substantiates this claim showing that collaborative R&D subsidies impact regions’ innovation growth when providing access to related variety and embedding regions into central positions in cross-regional knowledge networks.

New Publication on regional cooperation and innovation

coverMy paper, „An investigation of the relation between cooperation and the innovative success of German regions„, has been published in Spatial Economic Analysis. The paper is co-authored by Matthias Bürger and Thomas Brenner.



Concepts like regional innovation systems, innovative milieu and learning regions emphasise the positive contribution of intra-regional cooperation to firms’ innovation performance. This claim is, however, primarily backed by qualitative evidence, as few studies test this issue with quantitative approaches. Using data on co-application and co-invention of patents for 270 German labour market regions, this study shows that cooperation intensity and regions’ innovation efficiency are empirically associated in a negative way. This particularly concerns missing or very extensive inter-regional cooperation. In contrast, medium intensities of regional cooperation have rather positive effects.
