Empirical results on the link between growth and diversity in (un)related industries proved to be highly dependent on the specific regional and temporal context. Making use of highly disaggregated employment data at the sub-regional level, we find that higher employment growth in Austria is...

This paper investigates the effect of related and unrelated variety on regional growth in West Germany. In particular, we analyze the role of regional absorptive capacity and new business formation for these effects. We find that West German regions benefit from both types of varieties. The...

Software engineering is a field with strong geographic concentration, with Silicon Valley as the epitome of a tech cluster. Yet, most studies on the productivity effects of agglomerations measure innovation with patent data, thus capturing only a fraction of the industry's activity. With data...

In this paper, we examine the macro-to-micro-transition of cluster externalities to firms and how it is affected by the macroeconomic instability caused by the recessionary shock of 2008/2009. Using data from 16,166 manufacturing and business services firms nested in 390 German regions, we...

We design a conceptual framework for linking two approaches: the literature on absorptive capacity and the literature on spatial knowledge spillovers. Regions produce new knowledge, but only part of it is efficiently adopted in the economy; the share of efficiently adopted technology depends on...

A key concept in the economics of innovation is the 'public good' nature of knowledge. This generates a tension between incentivizing knowledge production by allowing knowledge creators appropriate the economic benefits and encouraging its diffusion to enhance the social return to knowledge...

This paper investigates how physical, organisational, institutional, cognitive, social, and ethnic proximities between inventors shape their collaboration decisions. Using a new panel of UK inventors and a novel identification strategy, this paper systematically explores the net effects of all...

In this paper we explore the impact of place-based innovation policy in Europe. We focus on the effects of Smart Specialisation strategies on the labour productivity of regional economies. We design an analytical framework that takes into account the entrepreneurial discovery process through...

This paper exploits a short-lived cooperation program between the U.S.S.R. and China, which led to the construction of 156 "Million-Rouble plants" in the 1950s. We isolate exogenous variation in location decisions due to the relative position of allied and enemy airbases and study the long-run...
