You are who your friends are : an experiment on trust and homophily in friendship networks

Kataria, Mitesh; Winter, Fabian - 2013

We study the existence of homophily (i.e. the tendency for people to make friends with people who are similar to themselves) with respect to trustworthiness. We ask whether two friends show similarly trustworthy behavior towards strangers, and whether this is anticipated by outsiders. We develop...

Dynamics of information exchange in endogenous social networks

Acemoglu, Daron; Bimpikis, Kostas; Ozdaglar, Asuman E. - In: Theoretical economics : TE ; an open access journal in … 9 (2014) 1, pp. 41-97

We develop a model of information exchange through communication and investigate its implications for information aggregation in large societies. An \textit{underlying state} determines payoffs from different actions. Agents decide which others to form a costly \textit{communication link} with,...

Diffusion of behavior in dynamic networks

König, Michael D. - 2016 - This version: March 28, 2016

We analyze binary choice models in communication networks, in which both, the formation of links in the network as well as the action choices are endogenous. We provide a complete characterization of the equilibrium action choices and networks, where agents choose their strategies - actions and...

Core and Periphery in Endogenous Networks

Hojman, Daniel; Szeidl, Adam - 2006

Many economic and social networks share two common organizing features: (1) a core-periphery structure; (2) positive correlation between network centrality and payoffs. In this paper, we build a model of network formation where these features emerge endogenously. In our model, the unique...

Social Capital and Social Quilts : Network Patterns of Favor Exchange

Jackson, Matthew O.; Rodríguez Barraquer, Tomás; Xu Tan - 2013

We examine the informal exchange of favors in societies such that any two individuals interact too infrequently to sustain exchange, but such that the social pressure of the possible loss of multiple relationships can sustain exchange. Patterns of exchange that are locally enforceable and...
