Studying the interaction between preference and capacity manipulation in matching markets, we prove that acyclicity is a necessary and su!cient condition that guarantees the stability of a Nash equilibrium and the strategy-proofness of truthful capacity revelation under the hospital-optimal and...

This paper analyzes the role of acyclicity in singleton cores. We show that the absence of simultaneous cycles is a sufficient condition for the existence of singleton cores. Furthermore, acyclicity in the preferences of either side of the market is a minimal condition that guarantees the...

Proposers strategically formulate legislative bills before voting takes place. However, spatial voting models that estimate legislator’s ideological preferences do not explicitly consider this fact. In our model, proposers determine the ideology and valence of legislative bills to maximize...

We study the consequences of bilateral market mergers. We first characterize the relationship between the M-optimal stable matching in the original markets with the M-optimal stable matching in the new market formed after the merger of the original markets. Then, we characterize the conditions...

This This paper determines the probability a large electorate will take take the correct decision under qualified majority rules. The model allows the competence of each elector to vary with the size of the electorate, thus the results represent a connection between "naive" and "strategic"...

In this paper, we present a model of implementation where infeasible allocations are converted into feasible ones through a process of renegotiation that is represented by a reversion function. We describe the maximal set of Social Choice Correspondences that can be implemented in Nash...
