چکیده

This paper addresses the existence of Nash networks for the one-way flow model of Bala and Goyal (2000) in a number of different settings. We provide conditions for the existence of Nash networks in models where costs and values of links are heterogeneous and players obtain resources from others through the directed path between them. We find that costs of establishing links play a vital role in the existence of Nash networks. Next we examine the existence of Nash networks when there are congestion effects in the model.

DEPARTMENT OF ECONOMICS WORKING PAPER SERIES (Non-)Existence and Scope of Nash Networks

For the connections model of strategic network formation, with two-way flow of information and without information decay, specific parameter configurations are given for which Nash networks do not exist. Moreover, existence and the scope of Nash network architectures are briefly discussed. JEL Classification: C72, D85

DEPARTMENT OF ECONOMICS WORKING PAPER SERIES Heterogeneity in Nash Networks

Heterogeneity in Nash networks can arise due to differences in the following four variables: (i) the value of information held by agents, (ii) the rate at which information decays or loses its value as it traverses the network, (iii) the probability with which a links transmits information, and (iv) the cost of forming a link. In this paper we examine Nash networks, efficient networks and the e...

DEPARTMENT OF ECONOMICS WORKING PAPER SERIES Partner Heterogeneity Increases the Set of Strict Nash Networks

Galeotti et al. (2006, [2]) show that all minimal networks can be strict Nash in two-way flow models with full parameter heterogeneity while only inward pointing stars and the empty network can be strict Nash in the homogeneous parameter model of Bala and Goyal (2000, [1]). In this note we show that the introduction of partner heterogeneity plays a major role in substantially increasing the set...

DEPARTMENT OF ECONOMICS WORKING PAPER SERIES Heterogeneity and Link Imperfections in Nash Networks

Heterogeneity in Nash networks with two-way flow can arise due to differences in the following four variables: (i) the value of information held by players, (ii) the rate at which information decays as it traverses the network, (iii) the probability with which a link transmits information, and (iv) the cost of forming a link. Observe that the second and third forms of heterogeneity are also ins...

A Note on Existence of Nash Networks in One-way Flow Models”

The importance of networks is pervasive and now well documented. Among the growing litterature on the formation of networks, a few papers have explored the impact of heterogeneity, although this is a distinctive feature. Galeotti (2006, [3]) is one exception. The author introduces agents heterogeneity in one way flow models of network formation and characterize the architectures of Nash network...
