A number of heterogeneous items are to be sold to a group of potential bidders. Every bidder knows his own values over the items and his own budget privately. Due to budget constraint, bidders may not be able to pay up to their values. In such a market, a Walrasian equilibrium usually fails to...

We examine a housing market with price controls and show how the allocation problem can be solved through a price system. We demonstrate that the auction of Talman and Yang (2008) always generates a core allocation, thus resulting in a Pareto efficient and stable outcome.

This paper considers the optimality of setting a secret reserve price in ascending auctions. Contrary to intuition, an ascending auction is no longer equivalent to a second price auction when the reserve price is secret. We determine the seller's optimal reserve price policy when the bidders'...

We examine ascending auctions with independent private values and a buyout option. The buyout option gives each buyer the opportunity to end the auction prematurely and acquire the object for a fixed price. We fully characterize the unique symmetric equilibrium and show that buyers with...

Price controls are used in many regulated markets and well recognized as the cause of market inefficiency. This paper examines a practical housing market in the presence of price controls and provides a solution to the problem of how houses should be efficiently allocated among agents through a...

This paper considers a multi-unit ascending auction with two players and common values. A large set of equilibria in this model is not robust to a small reputational perturbation. In particular, if there is a positive probability that there is a type who always demands many units, regardless of...

Recently Talman and Yang (2008) examined an assignment market under price control. In the market a number of heterogeneous items are to be sold to several bidders. Each bidder has a valuation on each item. The seller has a reservation price for every item. Meanwhile every item has a ceiling...

This paper investigates the perfect Bayesian equilibrium in an ascending-price core-selecting auction, which is recently used in some countriesʼ spectrum license auctions. We suppose that there are two identical items, two small bidders, and one large bidder. The small bidders demand only one...
