In competitive procurement auctions, bids often have the form of unit-price contracts (UPCs). We show that optimal bidding behavior in UPC auctions is typically nonmonotonic and therefore may lead to inefficient allocations. However, UPC auctions may still be desirable for the buyer when...

This paper studies the incentives for interim voluntary disclosure of verifiable information in probabilistic all-pay contests. Provided that the contest is uniformly asymmetric, full revelation is the unique perfect Bayesian equilibrium outcome. This is so because the weakest type of the...

This paper identifies simple conditions for monotone comparative statics of a unique equilibrium in the Akerlof-Wilson model. Separate conditions apply to trade volume and price. Trade volume increases when supply becomes both stronger and more elastic. In contrast, price decreases when supply...
