We build an overlapping generations model where an individual sees higher returns to adopting a behavior as many neighbors adopt the behavior. We show that overlap in the state of a parent and child's neighborhood can lead to correlation in parent-child behavior independent of any parent-child...

In our model, workers are embedded within a network of social relationships and can communicate through word-of-mouth. They can find a job either through formal agencies or through informal networks of contacts (word-of-mouth communication). From this micro scenario, we derive an aggregate...

This paper analyses the interplay between social structure and information exchange in two competing activities, crime and labour. We consider a dynamic model in which individuals belong to mutually exclusive two-person groups, referred to as dyads. There are multiple equilibria. If jobs are...

We propose a dynastic model in which individuals are born in an educated or uneducated environment that they inherit from their parents. We study the role of social networks on the correlation in the parent-child educational status independent of any parent-child interaction. We show that the...

Delinquents are embedded in a network of relationships. Social ties among delinquents are modelled by means of a graph where delinquents compete for a booty and benefit from local interactions with their neighbors. Each delinquent decides in a non-cooperative way how much delinquency effort he...

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...

The aim of this paper is to understand the interactions between productive effort and the creation of synergies that are the sources of technological collaboration agreements, agglomeration, and social interactions. We model this interaction in a way that allows us to characterize how agents...

We present a model where agents care about their neighbors' actions and can pressure them to take certain actions. Exerting pressure is costly for the exerting agent and it can impact the pressured agents by either lowering the cost of taking the action (which we call "positive pressure" ) or...

Delinquents are embedded in a network of relationships. Each delinquent decides in a non-cooperative way how much delinquency effort he will exert. We characterize the Nash equilibrium and derive an optimal enforcement policy, called the key-player policy. We then extend our characterization of...
