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...

In this paper, we study the evolution of private military corporations (PMCs), which are for-profit organizations that subcontract military field services to sovereign authorities as well as to others. Between Eisenhower's famous “military-industrial complex” speech in 1961 and the post-9/11...

This study examines the possibility that hybrid network positions that balance a firm's access to structural holes (Burt, 1992) and dense interconnections (Coleman, 1988) may outperform positions emphasizing one or the other alone. To do this, we estimate models of U.K. investment bank...

Our goal is to assess and consolidate the current state-of-the-art in organizational ecology. To accomplish this we review major theoretical statements, empirical studies, and arguments that are now being made. Although we attempt to survey ecological approaches to organizations comprehensively,...

Interfirm networks often take on characteristics consistent with the notion of a small world - they are locally clustered into dense sub-networks or cliques that are sparsely connected by a small number of ties that cut across the cliques, linking network members through a relatively small...

Using detailed data on Canadian biotechnology firms during the 1990s, we explore the geographic scope of knowledge spillovers and the balance spillover-seeking and expropriation-avoidance in entrants locations. Our findings indicate that knowledge spillovers are highly localized, with entrants...

Using detailed data on Canadian biotechnology firms during the 1990s, we explore the geographic scope of knowledge spillovers and the balance spillover-seeking and expropriation-avoidance in entrants' locations. Our findings indicate that knowledge spillovers are highly localized, with entrants...

We examine factors influencing the relative productivity of different geographic locations. Our analysis of the Canadian biotechnology industry during the 1990s reveals that inventive and uninventive locations are distinguishable within small geographic areas corresponding to roughly 7,000...

We introduce a formal language for describing epistemic states in networks at the individual (node, or agent) and interactive (multi-node) levels and at multiple epistemic levels (knowledge as well as knowledge about knowledge) and show how it allows us to represent states of belief, confidence...
