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...

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...

We model knowledge diffusion in a population of agents situated on a network, interacting only over direct ties. Some agents are by nature traders, others are by nature "givers": traders demand a quid pro quo for information transfer; givers do not. We are interested in efficiency of diffusion...

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...

[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...
