Finite population non-cooperative games with linear-quadratic utilities, where each player decides how much action she exerts, can be interpreted as a network game with local payoff complementarities, together with a globally uniform payoff substitutability component and an ownconcavity effect....

We build a model where investments in human capital depend on the state of an individual's social network. We show that correlation patterns between parents' and children's human capital investment and income depend on the structure of their social network. Heavier reliance on the social network...

This paper analyses the interplay between social structure and information exchange in two competing activities, crime and labor. We consider a dynamic model in which individuals belong to mutually exclusive two-person groups, referred to as dyads. Two individuals belonging to the same dyad hold...

We present a model of labor markets that accounts for the social network through which agents hear about jobs. We show that an improvement in the wage or employment status of either an agent's direct or indirect contacts leads to an increase in the agent's employment probability and expected...

This paper analyzes the early research performance of PhD graduates in labor economics, addressing the following questions: Are there major productivity differences between graduates from American and European institutions? If so, how relevant is the quality of the training received (i.e....

Some bilingual societies exhibit a distribution of language skills that can- not be explained by economic theories that portray languages as pure communication devices. Such distribution of skills are typically the result of public policies that promote bilingualism among members of both speech...

Social capital – a dense network of associations facilitating cooperation within a community – typically leads to positive political and economic outcomes, as demonstrated by a large literature following Putnam. A growing literature emphasizes the potentially "dark side" of social capital....

This paper shows that models where preferences of individuals depend not only on their allocations, but also on the well-being of other persons, can produce both large and testable effects. We study the allocation of workers with heterogeneous productivities to firms. We show that even small...

We study the effects of competition in a context in which people's actions can not be contractually fixed. We find that in such an environment the very presence of competition does neither increase efficiency nor does it yield any payoff gains for the short side of the market. We also find that...

Does ethical differentiation of products affect market behavior? We examined this issue in triopolistic experimental markets where producers set prices. One producer's costs were higher than the others. In two treatments, the additional costs were attributed to compliance with ethical...
