An auctioneer faces a pool of potential bidders that changes over time. She can delay the auction at a cost, in the hopes of having a thicker market later on. We identify a property of the distribution of bidder values—its “price elasticity”—that governs the distortions caused by revenue...

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model where a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract's scope. In this model, the buyer balances the need to incentivize...

A platform matches agents from two sides of a market to create a trading opportunity between them. The agents subscribe to the platform by paying subscription fees which are contingent on their reported private types, and then engage in strategic interactions with their matched partner(s). A...

This paper proposes a simple model for multiple second-price auctions which run parallel to each other, in the sense that though they might not begin or end at the same time, they have certain periods of overlap. We characterize the equilibrium bidding strategy of the buyers and the equilibrium...

We study the information design problem in a single-unit auction setting. The information designer controls independent private signals according to which the buyers infer their binary private value. Assuming that the seller adopts Myerson (1981) optimal auction in response, we characterize both...

This paper extends the results in Hidvegi et al. (2006) to the case when the number of bidders is common knowledge in an English auction with buy-out. In that case when some bidders drop out, the remaining bidders have to update their information, and change the threshold auction price at which...

We present a model of a discriminatory price auction in which a large bidder competes against many small bidders, followed by a post-auction resale stage in which the large bidder is endogenously determined to be a buyer or a seller. We extend results on first-price auctions with resale to this...

We consider a multi-dimensional procurement problem in which sellers have private information about their costs and about a possible design flaw. The information about the design flaw is necessarily correlated. We solve for the optimal Bayesian procurement mechanism that implements the efficient...

The price mechanism is fundamental to economics but difficult to reconcile with incentive compatibility and individual rationality. We introduce a double clock auction for a homogeneous good market with multidimensional private information and multiunit traders that is deficit‐free, ex post...

We study all-pay auctions with budget-constrained bidders who have access to fair insurance before bidding simultaneously over a prize. We characterize a unique equilibrium for the special cases of two bidders and one prize, show existence and a heuristic for finding an equilibrium in the case...
