We study security-bid auctions in which bidders compete by bidding with securities whose payments are contingent on the realized value of the asset being sold. Such auctions are commonly used, both formally and informally. In formal auctions, the seller restricts bids to an ordered set, such as...

We consider the strategic timing of information releases in a dynamic disclosure model. Because investors don't know whether or when the firm is informed, the firm will not necessarily disclose immediately. We show that bad market news can trigger the immediate release of information by firms....

We analyze an infinite stage, alternating offer bargaining game in which the buyer knows the gains from trade but the seller does not. Under weak assumptions the game has a unique candidate Perfect Sequential Equilibrium, and it can be solved by backward induction. Equilibrium involves the...

This paper presents a wage bargaining model in which the employer and employee are each uncertain about the other's reservation wage. Under specified circumstances, the model's equilibrium is shown to involve unilateral wage setting and inefficient labor turnover. In addition, aggregate demand...

This paper develops and implements a statistical methodology to account for the equilibrium effects (aka adverse selection) in design of risk adjustment formula in health insurance markets. Our setting is modeled on the situation in Medicare and the new state Exchanges where individuals sort...

Health plans paid by capitation have an incentive to distort the quality of services they offer to attract profitable and to deter unprofitable enrollees. We characterize plans' rationing as imposing a show that the profit maximizing shadow price depends on the dispersion in health costs, how...

We study the question of whether there exist strategies whereby countries are able to sustain a cartel or collusive behavior when bargaining with a bank over the amount of debt to be repaid. We show that despite the existence of economies to scale in bargaining--if commitment were possible the...

This paper models the wage-contract negotiation procedure between a union and a firm as a sequential bargaining process in which the unionalso decides, in each period, whether or not to strike for the duration of that period. We show that there exist subgame-perfect equilibria in which the union...
