Study on the impact of wind turbines on tourism demand

windTogether with Christoph Alfken I conducted a study on the impact of wind turbines on tourism demand in German municipalities. It is entitled: Gone with the wind? The impact of wind turbines on tourism demand. The study is accepted for publication in the journal Energy Policy, a working paper version can be downloaded here.


While wind energy production is relatively free from environmental externalities such as air pollution, it is frequently considered to negatively impact landscapes’ visual aesthetic values, thereby inducing negative effects on tourism demand. Existing evidence for Germany indeed points towards a negative relationship between tourism demand and wind turbine construction. However, the existing studies primarily rely on interview data and simple bivariate statistics. In contrast, the analysis makes use of secondary statistics on tourism and wind turbine locations at the level of German municipalities. Using spatial panel regression techniques, the study confirms a negative relation between wind turbines around municipalities and tourism demand for municipalities not located near the coast. In the latter regions, the relation between wind turbines and tourism demand is more complex.


New publication on clusters, R&D subsidies, and knowledge networks

My paper, „Another cluster premium: Innovation subsidies and R&D collaboration networks“, has been published in Research Policy. The paper is co-authored by Dirk Fornahl (University of Bremen) and Andrea Morrison (Utrecht University). It can be downloaded here.


This paper investigates the allocation of R&D subsidies with a focus on the granting success of firms located in clusters. On this basis it is evaluated whether firms in these clusters are differently embedded into networks of subsidized R&D collaboration than firms located elsewhere. The theoretical arguments are empirically tested using the example of the German biotechnology firms’ participation in the 6th EU-Framework Programmes and national R&D subsidization schemes in the early 2000s.

We show that clusters grant firms another premium to their location, as they are more likely to receive funds from the EU-Framework Programmes and hold more favorable positions in national knowledge networks based on subsidies for joint R&D.


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.

Publication on co-evolution of proximities

My paper „The co-evolution of proximities – a network level study“ has been published in Regional Studies. It can be downloaded here.


Theco-evolution of proximities – a network level study, Regional Studies. Little isknownabouthownetwork structures and proximity relations between linked actors evolve over time. This paper argues that a number of networks’ internal proximity structures are interrelated, which may give rise to specific types of co-evolution dynamics. An empirical investigation tests these arguments using information on the evolution of 280 networks of subsidized research and development (R&D) collaboration in Germany. The empirical findings clearly confirm the existence of systematic and dynamic interrelatedness between proximities. In this way, the paper underlines the need to consider such relations when investigating the evolution of 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.

Publication on artists‘ mobility

coverMy paper, „Factors explaining the spatial agglomeration of the creative class: Empirical evidence for German artists„, has been published in European Planning Studies. The paper is co-authored by Christoph Alfken and Rolf Sternberg.


The paper contributes to the on-going debate about the relative importance of economic and amenity-related location factors for attracting talent or members of the creative class. While Florida highlights the role of amenities, openness and tolerance, others instead emphasize the role of regional productions systems, local labour markets and externalities. The paper sheds light on this issue by analysing the changes in the spatial distribution of four groups of artists over time: visual artists, performing artists, musicians and writers. Little evidence is found for amenity-related factors influencing the growth rates of regional artist populations. Moreover, artists are shown to be a heterogeneous group inasmuch as the relative importance of regional factors significantly differs between artistic branches.
