Patacchini, Eleonora; Zenou, Yves - 2021

We analyse the effect of strong and weak ties on the individual probability of finding a job. Using the dynamic model of Calvó-Armengol and Jackson (2004), two results are put forward: (i) the individual probability of finding a job is increasing in the number of strong and weak ties; (ii) the...

Peer effects and social networks in education

Calvó-Armengol, Antoni (contributor); … - 2008

This paper studies whether structural properties of friendship networks affect individual outcomes in education. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Katz-Bonacich centrality measure. This...

Oppositional identities and the labor market

Battu, Harminder (contributor); Mwale, MacDonald (contributor) - 2005

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

How urbanization affects employment and social interactions

Satō, Yasuhiro; Zenou, Yves - 2014

We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also...

Key players in co-offending networks

Lindquist, Matthew J.; Zenou, Yves - 2014

empirical tests of the key player policy in a real world setting. This policy defines a micro-founded strategy for removing the … theoretical predictions of the key player policy with real world outcomes. By focusing on networks for which the key player has … disappeared over time, we show that the theoretical predicted crime reduction is close to what is observed in the real world. We …

The economic consequences of social network structure

Jackson, Matthew O.; Rogers, Brian; Zenou, Yves - 2016

We survey the literature on the economic consequences of the structure of social networks. We develop a taxonomy of "macro" and "micro" characteristics of social interaction networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

Social networks and interactions in cities

Helsley, Robert W.; Zenou, Yves - 2011

We examine how interaction choices depend on the interplay of social and physical distance, and show that agents who are more central in the social network, or are located closer to the geographic center of interaction, choose higher levels of interactions in equilibrium. As a result, the level...
