In this paper we study the conditions under which efficient behavior can spread from a finite initial seed group to an infinite population living on a network. We formulate conditions on payoffs and network structure under which overall contagion occurs in arbitrary regular networks. Central in...

This paper is about the diffusion of cooperation in an infinite population of networked individuals repeatedly playing a Prisoner’s Dilemma. We formulate conditions on payoffs and network structure such that, starting from an initial seed group, imitative learning results in the overall...

This paper presents an economic model of R&D network formation through the creation of strategic alliances. Firms are randomly endowed with knowledge elements. They base their alliance decisions purely on the technological fit of potential part- ners, ignoring social capital considerations and...

We aim at giving a general view of the context in which appears the latest

The object of this contribution is to address the question of the ownership of the firm. Both law and economics shape representations of the world: law focuses on rules and justice; economics focuses on efficiency and allocation. They describe common situations and "objects'' such as firms and...

Based on French data describing the characteristics of the entrepreneurs and their project, this paper studies the differences between the determinants of survival for innovative and non-innovative micro-enterprises. We show that the survival of innovative and non-innovative enterprises is...

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...
