This article investigates the contribution of regions to aggregate growth. We find a great degree of heterogeneity in the performance of Territorial Level 3 ( TL3) regions of the OECD (Organization for Economic Cooperation and Development). The regional contributions to aggregate growth follow a...

This paper brings together the latest data and OECD productivity indicators in different areas with the aim of reviewing the main productivity trends over the past decade, comparing the United States, Europe and to some extent Japan. Concerning economy wide indicators of productivity, the...

This paper investigates the impact of complementarity reforms on growth and how it depends on GDP per capita. Based on reform data for six policy areas compiled from various sources during the period 1994-2006 for over 100 countries, we compute composite indicators of reform level and...

A key question raised in recent years is which factors determine the structure of inter-organizational networks. While the focus has primarily been on different forms of proximity between organizations, which are determinants at the dyad level, recently determinants at the node and structural...

Firms’ embeddedness into knowledge networks has received much attention in the literature. However, little is known about the composition of firms’ ego-networks with respect to different types of proximities. Based on survey data of 295 firms in eight European regions, we show that the...

Concepts like regional innovation systems, innovative milieu, and learning regions emphasize the positive contribution of intra-regional cooperation to firmsÕ innovation performance. Despite substantial numbers of case studies, the quantitative empirical evidence for this claim is thin. Using...

The importance of network structures for the transmission of knowledge and the diffusion of technological change has been emphasized in economic geography. Since network structures drive the innovative and economic performance of actors in regional contexts, it is crucial to explain how networks...

Measuring the innovation performance of regions or nations has been repeatedly done in the literature. What is missing in the literature is a discussion of what innovation performance of a region means. How do regions or nations contribute really to the innovation output of firms? And how can...

A growing body of work emphasizes the importance of regional factors for regional innovativeness. In this paper, about seventy variables approximating the social-economic characteristics of regions are aggregated to twelve regional factors. In four industry-specific set-ups their influence on...

The importance of geographical proximity for interaction and knowledge sharing has been discussed extensively in economic geography in recent years. There is increasing consensus that it is just one out of many types of proximities that might be relevant. We argue that proximity may be a crucial...
