We study the language choice behavior of bilingual speakers in modern societies, such as the Basque Country, Ireland andWales. These countries have two o cial languages:A, spoken by all, and B, spoken by a minority. We think of the bilinguals in those societies as a population playing repeatedly...

We study network formation with <em>n players</em> and link cost <em>α </em> 0. After the network is built, an adversary randomly deletes one link according to a certain probability distribution. Cost for player <em>ν</em> incorporates the expected number of players to which <em>ν</em> will become disconnected. We focus on...</em>

We study the solution concepts of partial cooperative Cournot-Nash equilibria and partial cooperative Stackelberg equilibria. The partial cooperative Cournot-Nash equilibrium is axiomatically characterized by using notions of rationality, consistency and converse consistency with regard to...

If actors want to reach a particular goal, they are often better off forming collaborative relations and investing together rather than investing separately. We study the coordination and cooperation problems that might hinder successful collaboration in a dynamic network setting. We develop an...

This paper provides an experimental test of a theory of endogenous network formation. A group of subjects face a decision problem under uncertainty. The subjects are endowed with a private information about the fundamentals of the problem, and they are supposed to make a decision one after the...

I develop a framework to explain why identity divides some communities and not others. An identity group is defined as a group of individuals with the same `culture'. A community is divided when different identities are socially segregated; a community is integrated when there is no social...
