We examine the dynamic formation and stochastic evolution of networks connecting individuals. The payoff to an individual from an economic or social activity depends on the network of connections among individuals. Over time individuals form and sever links connecting themselves to other individuals based on the improvement that the resulting network offers(More)
Network structure plays a significant role in determining the outcome of many important economic relationships; therefore it is crucial to know which network configurations will arise. We analyze the process of network formation in a dynamic framework, where self-interested individuals can form and sever links. We determine which network structures the(More)
There are many situations where two interacting individuals can benefit from coordinating their actions. We examine the endogenous choice of partners in such social coordination games and the implications for resulting play. We model the interaction pattern as a network where individuals periodically have the discretion to add or sever links to other(More)
We examine networks connecting individuals, where the payoff to an individual from an economic or social activity depends on the full network of connections among individuals. Individuals can form and sever links connecting themselves to other individuals based on the improvement that the resulting network offers them relative to the current network. As(More)
We examine a new class of games, which we call social games, where players not only choose strategies but also choose with whom they play. A group of players who are dissatisfied with the play of their current partners can join together and play a new equilibrium. This imposes new refinements on equilibrium play, where play depends on the relative(More)
There are many situations where people join groups, the number of groups is fixed, and where a person can only join a new group if the new group approves the person’s joining. We examine such situations where agents are concerned with either local status (each agent wants to be the highest status agent in his group) or global status (each agent wants to(More)
We prove existence of equilibria in bipartite social games, where players choose both a strategy in a game and a partner with whom to play the game. Such social games generalize the well-known marriage problem where players choose partners, but there are no endogenous choices subsequent to a matching.

It is well known that women’s career outcomes are tied to fertility decisions and that occasionally educated women who had planned to stay in the labor market after childbirth exit the market. We examine women’s career, fertility, and educational choices in an environment of uncertainty regarding the possibility of achieving both a high-powered career and a(More)
Silicon chips are taken for granted. They are, however, the heart of the majority of electronic products. Integrated electronic circuits of this sort increase the functionality of many devices, enabling them to do more, while making them smaller. Application-specific integrated circuit technology is becoming cheaper to purchase and can enhance performance(More)
