Innovation policy

My research activities include the analysis and evaluation of public innovation-oriented policies. A particular focus is on the growing subsidisation of joint R&D projects (projects realised by consortia of organisations) at the expense of support for individual R&D projects (projects are conducted by a single organisation). In this context, it is still largely unexplored if and if so in what cases supporting joint projects is superior to subsidising individual projects, how organisations’ embeddedness into inter-organizational knowledge networks changes, and hence, if policy tool influences the extent and way organizations access external knowledge.

Wind energy diffusion

New publication: Pulled or pushed? The spatial diffusion of wind energy between local demand and supply

Supply-push or demand-pull? In a new publication, Marcel Bednarz and I find that the spatial distribution of the German #wind #energy industry was stronger shaped by local #demand-pull than by local #supply-push effects. We use Bayesian survival models with...

Development of structural diversity

Updated values of technological complexity

An updated and extended version of the data on #technological #complexity is available.  I’ve re-calculated #Structural #Diversity for the years 1900 to 2016 (see plot) using the latest version of EPO #patents. Data (1970-2016) for download here. For technical details, see the publication:  https://doi.org/10.1371/journal.pone.0216856
