Galeotti, Andrea; Goyal, Sanjeev; Jackson, Matthew O.; … - Department of Economics, European University Institute - 2008
In a variety of contexts - ranging from public goods provision to information collection - a player's well-being depends on own action as well as on the actions taken by his or her neighbors. We provide a framework to analyze such strategic interactions when neighborhood structure, modeled in...

Heterogeneous Network Games: Conflicting Preferences
Hernandez, Penelope; Herrera, Edson Manuel Muñoz; … - Estructura de Recerca Interdisciplinar Comportament … - 2011
We propose a model of network games with heterogeneity introduced by endowing players with types that generate preferences among their choices. We study two classes of games: strategic complements or substitutes in payoffs. The payoff function depends on the network structure, and we ask how...

Random Walk-Based Segregation Measures
Ballester, Coralio; Vorsatz, Marc - In: The Review of Economics and Statistics 96 (2014) 3, pp. 383-401
We propose an intuitive way of how to measure segregation in social and spatial networks. Using random walks, we define … the segregation index as the probability that an individual meets an individual from the same social group. The … segregation index is a generalization of the isolation index and a homophily index introduced in Currarini, Jackson, and Pin (2009 …

Currarini, Sergio; Redondo, Fernando Vega - Dipartimento di Economia, Università Ca' Foscari Venezia - 2010
We study the formation of social ties among heteogeneous agents in a model where meetings are governed by agents' directed search. The aim is to shed light on the important issue of homophily (the tendency of agents to connect with others of the same type). The essential contribution of the...

Group design with endogenous associations
Weinberg, Bruce A. - In: Regional Science and Urban Economics 43 (2013) 2, pp. 411-421
The belief that people are affected by the groups in which they are active has long led policy makers to manipulate the groups to which people are exposed. This paper studies the optimal design of groups to maximize racial and ethnic integration. We show that the group composition that maximizes...
