We provide extensions of the Bulow and Klemperer (1996) result when the seller has value for the object above the minimum value of the buyers. The result may fail. We show that the seller does better with more participation and some exclusion than the optimal exclusion of buyers of low value...

We study the assignment of agents to clubs in a frictional market environment. Club entry is endogenous and clubs compete by posting reserve prices in a competing auctions game prior to the agents’ decisions regarding which club to visit. The competing auctions equilibrium is constrained...

In the matching with contracts literature, three well-known conditions (from stronger to weaker)–substitutes, unilateral substitutes (US), and bilateral substitutes (BS)–have proven to be critical. This paper aims to deepen our understanding of them by separately axiomatizing the gap between...

I propose a simple method to nonparametrically estimate the utility function in first-price, sealed-bid auctions when bidders’ participation is exogenous. Using a pair of bid densities, each for a different number of bidders, I establish a contraction mapping that converges to the true utility...
