A necessary and sufficient condition for dominant strategy implementability when preferences are quasilinear is that, for any individual i and any choice of the types of the other individuals, all k-cycles in i's allocation graph have nonnegative length for every integer k � 2. Saks and Yu...

We introduce a perfect price discriminating (PPD) mechanism for allocation problems with private information. A PPD mechanism treats a seller, for example, as a perfect price discriminating monopolist who faces a price schedule that does not depend on her report. In any PPD mechanism, every...

Is conformity amongst similar individuals consistent with self-interested behavior? We consider a model of incomplete information in which each player receives a signal, interpreted as an allocation to a role, and can make his action choice conditional on his role. Our main result demonstrates...

We introduce a subsidized Vickrey auction for cost sharing problems. Although the average, marginal, and serial cost sharing mechanisms are budget-balanced, they are not allocatively efficient and they do not induce players to truthfully reveal their values as a dominant strategy. The...

In this paper, we study the incentives for market concentration of (online and traditional) auction houses. Would sellers and buyers be better off if two separate auction houses merged? We suppose that each auction house has a separate clientele of sellers and buyers. Sellers value their...

Whether rationality of economic behavior increases with expected payoffs and decreases with the cognitive cost it takes to formulate an optimal strategy remains an open question. We explore these issues with field data, using individual bids from sealed-bid auctions in which we sold nearly...

We consider a two-player strategic bargaining model with discounting in which (i) the interim disagreement point in each period is stochastically determined at the beginning of the period, and (ii) the proposing player can delay in making an offer. Unlike many other bargaining models of complete...

Sections 8(a)(3) and 8(a)(5) of the National Labor Relations Act prohibit a firm from unilaterally increasing the wage it pays the union during the negotiation of a new wage contract. To understand this regulation, we study a counterfactual model where the firm can unilaterally increase wages...

We present a dynamic model of club formation in a society of identical people. Coalitions consisting of members of the same club can form for one period and coalition members can jointly deviate. The dynamic process is described by a Markov chain defined by myopic optimization on the part of...

The paper argues that multiple equilibria-whether non-stationary or stationary- are a generic property of dynamic rational expectations models. In light of this, this paper proposes a selection criterion for choosing between these multiple equilibria in an important class of dynamic rational...
