Although the literature converges regarding the reasons why and how networks of technology alliances are formed, there is still lack of agreement on what constitutes an optimal network structure, once it has been formed. The aim of this paper is to fill this void and to determine what...

There has been a recent surge of interest in social economics and social capital. Articles on social capital that are published in the last five years constitute more than 60 percent of all articles on social capital. Research on social capital is now massive and spans sociology, economics,...

This paper undertakes a critical review of existing spillover analyses and proposes a unique analytical framework for examining technological spillovers in a manufacturing industry setting. The proposed framework overlaps three different literature strands; cluster and network dynamics,...

Although intuitively appealing (and common), drawing network strategy implications from empirical evidence of network performance effects in pooled cross-section is not necessarily warranted. This is because network positions can influence both the mean and variance of firm performance....

We use a general equilibrium framework to study optimal health investment in a dynamic model where agents derive utility from consumption and health. The steady state and the dynamics of the model are studied under separable and non-separable preferences. A shock undermining health which...

Suppose that homogenous agents fully consume their time to invent new ideas and learn ideas from their friends. If the social network is complete and agents pick friends and ideas of friends uniformly at random, the distribution of ideas’ popularity is an extension of the Yule-Simon...

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...

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...

This is a model of knowledge exchange by means of informal interaction among agents in low technology clusters. What this study seeks to do is to colour these exchanges by placing them in an environment of complex social relations, test whether the small-world network structure is the most...

When agents use informal interaction to exchange knowledge, their production relations may develop as emergent properties of their social relations and may exhibit homophily. The Saliyar community cluster in India is an archetype of this. A preceding study by Cowan and Kamath (2012) had shown...
