Under-connected and over-connected networks

Hellmann, Tim; Buechel, Berno - 2009

Since the seminal contribution of Jackson & Wolinsky 1996 [A Strategic Model of Social and Economic Networks, JET 71, 44-74] it has been widely acknowledged that the formation of social networks exhibits a general conflict between individual strategic behavior and collective outcome. What has...

Power in the heterogeneous connections model: The emergence of core-periphery networks

Persitz, Dotan - 2009

The heterogeneous connections model is a generalization of the homogeneous connections model of Jackson and Wolinsky (1996) in which the intrinsic value of each connection is set by a discrete, positive and symmetric function that depends solely on the types of the two end agents. Core periphery...

Cooperation through imitation and exclusion in networks

Mengel, Friederike; Fosco, Constanza - 2009

We develop a simple model to study the coevolution of interaction structures and action choices in Prisoners' Dilemma games. Agents are boundedly rational and choose both actions and interaction partners via payoff-based imitation. The dynamics of imitation and exclusion yields polymorphic...

Knowledge Structures.

Network-independent partner selection and the evolution of innovation networks

Baum, Joel; Cowan, Robin; Jonard, Nicolas - United Nations University, Maastricht Economic and … - 2009

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...

Matching and network effects

Fafchamps, Marcel; Leij, Marco van der; Goyal, Sanjeev - Instituto Valenciano de Investigaciones Económicas (IVIE) - 2009

The matching of individuals in teams is a key element in the functioning of an economy. The network of social ties can potentially transmit important information on abilities and reputations and also help mitigate matching frictions by facilitating interactions among ¿screened¿ individuals. We...
