Cliques (of densely connected alliance partners) have been largely neglected in technological alliances studies. In this study, we show that cliques and their dynamics are an interesting angle, to analyze why certain firms are better in going beyond local search than others. Clique spanning ties...

Alliance cliques have been largely neglected in technological alliances studies. In this study we show that cliques offer an interesting angle to analyze why certain firms are better in going beyond local search than others. Clique spanning ties can be expected to have strategic advantages for...

Technology development in firms is frequently based on a combination of internal and external technological learning. Consequently, firms need to develop both technological capital (a patent portfolio) and alliance capital (a portfolio of technology alliances). This paper examines the...

In this paper we test the relation between cognitive distance and innovation performance of firms engaged in technology-based alliances. The key finding is that the hypothesis of an inverted U-shaped effect of cognitive distance on innovation performance of firms is confirmed. Moreover, as...

In this paper we analyze the innovative performance of alliance networks as a function of the technological distance between partners, a firm's network position (centrality) and total network density. We study how these three elements of an alliance network, apart and in combination, affect the...

This paper looks at the special characteristics of radical inventions. It tries to identify those variables that differentiate radical inventions from non-radical inventions. Since radical inventions are very important for the economy as a whole and for the individual firm performances,...

Although the literature converges regarding the reasons why and how networks of technology alliances are formed, there is still lack of agreement on what constitutes an optimal network structure, once it has been formed. The aim of this paper is to fill this void and to determine what...

External knowledge sourcing is increasingly important for corporate entrepreneurship. In this study, we examine the effect of external and relational uncertainty on the governance choice for inter-organizational technology sourcing. We develop a number of hypotheses about the impact of...
