We examine a society in which individuals gain utility from income and social approbation. Approbation is given to an unobservable trait, signalled through social mobility. Two environments are studied: in one players care for absolute approbation; in the other relative approbation matters. In...

Empirical research on strategic alliances has focused on the idea that partners are selected on the basis of social capital considerations. In this paper we emphasize instead the role of complementary knowledge stocks and knowledge dynamics, which have received surprisingly limited attention...

In traditional economics models of perfect competition agent's interactions are all mediated through the market. Interactions are anonymous, global and indirect. This is a powerful model, but we see many instances in which one, and sometimes all, of the previous characteristics fail to hold...

We model knowledge diffusion as agents exchanging ideas through a barter process. The model builds on empirical observations of informal knowledge trading among competing agents. The process takes place on a network substrate in which agents are nodes, and can trade only with those to whom they...

[eng] In this paper the evolution of networks is studied in an environment where innovation takes place as a resuit of agents bringing together their knowledge endowments. Agents freely form pairs that must constitute a stable matching in which the rankings are made on the basis of the...

In this paper, we model the formation of innovation networks as they emerge from bilateral decisions. In contrast to much of the literature, here firms only consider knowledge production, and not network issues, when deciding on partners. Thus, we focus attention on the effects of the knowledge...

This book re-examines the rationale for public policy, concluding that the prevailing ‘public knowledge' model is evolving towards a networked or distributed model of knowledge production and use in which public and private institutions play complementary roles. It provides a set of tools and...

The field of Strategic Management has explored a range of new questions regarding technical change, firm capabilities, and executive decision-making, producing insights into the development of firms and unfolding of competition over time. These insights point to the importance of industry...
