Although intuitively appealing (and common), drawing network strategy implications from empirical evidence of network performance effects in pooled cross-section is not necessarily warranted. This is because network positions can influence both the mean and variance of firm performance....

Using a large and novel data source, we study the structure of R&D collaboration net-works in the first five EU Framework Programmes (FPs). The networks display proper-ties typical for complex networks, including scale-free degree distributions and the small-world property. Structural features...

We use a general equilibrium framework to study optimal health investment in a dynamic model where agents derive utility from consumption and health. The steady state and the dynamics of the model are studied under separable and non-separable preferences. A shock undermining health which...

Network formation is often said to be driven by social capital considerations. A typical pattern observed in the empirical data on strategic alliances is that of small world networks: dense subgroups of firms interconnected by (few) clique-spanning ties. The typical argument is that there is...

The primary goal of this paper is to improve our understanding of the complex relationship between the positioning of companies in alliance networks and their innovative performance. In particular, we expect that a firm's innovative performance depends partly on its position in specific network...

Empirical research on strategic alliances has focused on the idea that alliance partners are selected on the basis of social capital considerations. In this paper we emphasize instead the role of complementary knowledge stocks (broadly defined) in partner selection, arguing not only that...

We describe the construction of a large and novel data set on R&D collaboration networks in the first five EU Framework Programmes (FPs), examine key features and provide economic interpretations for our findings. The data set is based on publicly available raw data that pre-sents numerous...

In this note we examine whether a position in a technology alliance block is accessible to everyone. It appears that partners are selected on the basis of distinctive attributes they have, which can inhibit outsiders to join these alliance groups. Our findings clearly indicate that alliance...

In this paper we empirically studied the relationship between network centrality and academic performance among a group of 47 PhD students from UNU-MERIT institute. We conducted an independent email survey and relied on social networks theory as well as standard econometric procedures to analyse...

Using innovation survey data on a sample of UK manufacturing firms, Laursen and Salter 2006 documented a non-monotonous relationship between external search strategies and firm-level innovative performance. We find partially similar results in a combined sample of Nigerian manufacturing and...
