Effi cient Entry in Competing Auctions ∗

نویسنده

  • Susan Vroman
چکیده

In this paper, we demonstrate the effi ciency of seller entry in a model of competing auctions in which we allow for both buyer and seller heterogeneity. This generalizes existing effi ciency results in the competitive search literature by simultaneously allowing for nonrival (many-on-one) meetings and private information. ∗We thank Andrzej Skrzypacz, our editor, and Jeremy Bulow for their helpful comments. We also thank Xiaoming Cai, who made substantial contributions to the online appendix.

Efficiency in Search and Matching Models: A Generalized Hosios Condition

When is the level of entry of buyers or sellers effi cient in markets with search and matching frictions? This paper generalizes the well-known Hosios condition for constrained effi ciency to a wide range of dynamic search and matching environments where the expected match output depends on the market tightness. The generalized Hosios condition is simple and intuitive: entry is constrained effi...

Sequential auctions, price trends, and risk preferences

We analyze sequential auctions where bidders are heterogeneous in risk exposures and exhibit non-quasilinear utilities. We derive an increasing pure strategy equilibrium for the sequential Dutch and Vickrey auctions respectively, with an arbitrary number of identical objects for sale. A suffi cient, and to certain extent necessary, condition for this result is that bidders’marginal utilities ar...

Rational Participation Revolutionizes Auction Theory

Potential bidders respond to a seller’s choice of auction mechanism for a common-value or a¢ liated-values asset by endogenous decisions whether to incur a participation cost (and observe a private signal), or forego competing. Privately informed participants decide whether to incur a bid-preparation cost and pay an entry fee, or cease competing. Auction rules and information ‡ows are quite gen...

Affi liation and Entry in First-Price Auctions with Heterogeneous Bidders: An Analysis of Merger Effects∗

In this paper, using timber sale auctions in Oregon, we study the merger effects within a general framework where bidders are heterogeneous and entry is endogenous. We propose an entry and bidding model within the affi liated private value (APV) framework and with heterogeneous bidders, and establish existence of the entry equilibrium and existence and uniqueness of the bidding equilibrium with...

Competing Auctions

This paper shows that larger auctions are more efŽ cient than smaller ones, but that despite this scale effect, two competing and otherwise identicalmarkets or auction sites of different sizes can coexist in equilibrium. We Ž nd that the range of equilibrium market sizes depends on the aggregate buyer–seller ratio, and also whether the markets are especially thin. (JEL: D44, L11)
