[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...

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...

In this paper, we model the impact of networks on knowledge growth in an in-novatingindustry. Specifically, we compare two mediums of knowledge exchange;random interaction, and the case in which interaction occurs on a fixed architec-ture.In a simulation study, we investigate how the medium of...

In this paper we study a society in which individuals gain utility from income and from social approbation. Income is correlated with class. Approbation is given to an unobservable trait, which must be signalled through the agent’s social mobility, i.e. class change. Mobility is driven by a...

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...

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...
