In this paper, we model college admissions under early decision in a many-to-one matching framework with two periods. We show that there exists no stable matching system, involving an early decision matching rule and a regular decision matching rule, which is nonmanipulable via early decision...

This paper defines "negotiation-proof Nash equilibrium'', a notion that applies to environments where players can negotiate openly and directly prior to the play of a noncooperative game. It recognizes the possibility that a group of self-interested players may choose, voluntarily and without...

We propose a concept of self-enforcing risk-sharing agreement that are robust not only to single-person deviations but also to potential deviations by subgroups, requiring that the deviating subgroup itself employs some self-enforcing risk-sharing agreement. We observe that the stability of...

This paper takes an axiomatic approach to find rules for allocating the value of a network when the externalities generated across components are identifiable. Two new, and different, allocation rules are defined and characterized in this context. The first one is an extension of the...

We consider a two-stage public goods provision game: In the first stage, players simultaneously decide if they will join a contribution group or not. In the second stage, players in the contribution group simultaneously offer contribution schemes in order to influence the government’s choice...

An individual bank can put the whole banking system at risk if its losses in response to shocks push losses for the system as a whole above a critical threshold. We determine the contribution of banks to this systemic risk using a generalisation of the Shapley value; a concept originating in...

Institutions affect prospects for economic growth and development. In this paper a condition on the primitives determines whether an economy supports markets. Agents differ in land holdings, skill, and power. A competitive market assigns land efficiently to the skilled, not necessarily to the...
