Rarely, if ever. do parties contemplating a joint project commit resources without engaging in nonbindin- discussions about who does what. To examine the role of such discussions, we model the investment decision as a voluntary contribution game where each player is privately informed of her...

This paper develops an empirical strategy to identify maverick-like behavior. This strategy includes measuring two behavioral dimensions: (i) the extent to which particular suppliers underprice rivals; and (ii) the timing of the suppliers' responses to systemic cost changes. This strategy is...

We examine a problem with n players each facing the same binary choice. One choice is superior to the other. The simple assumption of competition - that an individual's payoff falls with a rise in the number of players making the same choice, guarantees the existence of a unique symmetric...

We examine the role of seller bidding and reserve prices in an infinitely repeated independent-private-value (IPV) ascending-price auction.The seller has a single object that she values at zero.At the end of any auction round, she may either sell to the highest bidder or pass-in the object and...

We make three contributions to the theory of contracting under asymmetric information. First, we establish a competitive revelation principle for contracting games in which several principals compete for one privately informed agent. In particular, we show that given any profile of incentive...

We prove equilibrium existence for economies with separable utilities, uncountable state space, incomplete markets without any special assumptions on endowments

We introduce the concept of inconsequential arbitrage and, in the context of a model allowing short-sales and half-lines in indifference surfaces, we prove that inconsequential arbitrage is sufficient for existence of equilibrium. With a slightly stronger condition of local nonsatiation than...
