This article considers manipulation of collective choice — in such environments, a potential alternative is powerful only to the degree that its introduction can affect the collective decision. Using the Banks set (Banks, 1985), we present and characterize alternatives that can, and those...

In tournaments, one alternative contests another if is a “winner” among only alternatives that beat it. This paper examines the consequences and limitations of the contestation relation by considering a procedure in which alternatives that are contested are iteratively eliminated from...

We consider an extension of Tullock's (1980) N-player contest under which prize valuations may vary across players. We show that the pure-strategy equilibrium of this contest is unique. We also establish the following results: rent dissipation increases, individual winning probabilities...

We investigate an economy in which firms have different risks to go bankrupt. We observe two things: first, workers in firms with higher bankruptcy risk (bad firms) always work less than workers in good firms. Second, the CEOs of bad firms may nonetheless receive larger wages. Copyright...

We consider a multi-period auction with a seller who has a single object for sale, a large population of potential buyers, and a mediator of the trade. The seller and every buyer have independent private values of the object. The mediator designs an auction mechanism which maximizes her revenue...

An auction house runs a second-price auction with a possibility of resale through re-auctions. It collects listing and closing fees from the seller. We find the fees which maximize the revenue of the auction house. In particular, we show that the optimal listing fee is zero. Our findings are...

We consider a model where sellers make repeated attempts to sell an object via two competing auction houses. An auction house that attracts a seller runs a Vickrey auction among a random sample of buyers and collects two fees: a listing fee and, if the object is sold, a closing fee. We...

We consider mechanisms for allocating a common-value prize between two players in an incomplete information setting. In this setting, each player receives an independent private signal about the prize value. The signals are from a discrete distribution and the value is increasing in both...

This paper analyzes an evolutionary version of the Public Good game in which boundedly rational agents can use imitation and best-reply decision rules. Several possibilities for both decision rules to be present in the population are considered. I show that altruistic behavior might survive if...
