We construct a model with private information in which consumers write dynamic contracts with financial intermediaries. A role for money arises due to random limited participation of consumers in the financial market. Without defection constraints, a Friedman rule is optimal, the mean and...

We construct a dynamic heterogeneous-agent model with random uninsurable endowments. Two allocation mechanisms are considered, one with long-term complete credit arrangements under private information, and one with incomplete competitive markets. A role for money arises due to random limited...

Morelli (American Political Science Review, 1999) provides a majoritarian bargaining model in which the parties make payoff demands and the order of moves is chosen by the leading party. Morelli's main proposition states that the ex post distribution of payoffs inside the coalition that forms is...

In this paper we study the restriction, to the class of bargaining problems with coalition structure, of several values which have been proposed on the class of non-transferable utility games with coalition structure. We prove that all of them coincide with the solution independently studied in...

We propose a simple non-cooperative mechanism of network formation in cost spanning tree problems. The only subgame equilibrium payoff is efficient. Moreover, we extend the result to the case of budget restrictions. The equilibrium payoff can them be easily adapted to the framework of Steiner trees.

We study minimum cost spanning tree problems and define a cost sharing rule that satisfies many more properties than other rules in the literature. Furthermore, we provide an axiomatic characterization based on monotonicity properties.

We consider a random matching model without monetary exchange where agents have complete access to each others’ histories. Exchange is motivated by risk sharing given random unobservable incomes. There is capital accumulation and an endogenous interest rate. The key feature of this environment...

In cooperative games in which the players are partitioned into groups, we study the incentives of the members of a group to leave it and become singletons. In this context, we model a non-cooperative mechanism in which each player has to decide whether to stay in his group or to exit and act as...
