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...

The fixed rate tender is one of the main procedural formats relied upon by central banks in their implementation of monetary policy. This fact stands in a somewhat puzzling contrast to the prevalent view in the theoretical literature that the procedure, by fixing interest rate and quantity at...

It is argued that bidders in liquidity-providing central bank operations should typically possess declining marginal valuations. Based on this hypothesis, we construct an equilibrium in central bank refinancing operations organised as variable rate tenders. In the case of the discriminatory...

I find that current US's and EU's Antitrust laws -- in particular their "moderate"' leniency programmes that only reduce or at best cancel sanctions for price-fixing firms that self-report -- may make collusion enforceable even in one-shot competitive interactions, like Bertrand oligopolies and...

We study the government's decision to sell a state-owned enterprise to strategic investors in a common value auction setting. The government can choose to sell his control stake all at once, or to design a sequential auction of shares. The sequential auction allows information transmission, so...

We consider two ascending auctions and show that many of the (unwanted) collusive or signaling equilibria studied in the literature in the framework of the SEAMO (simultaneous English auction for multiple objects) don't have a counterpart in the JAMO (Japanese auction for multiple objects). We...

This paper analyzes two-stage rank-order tournaments. A principal decides (i) how to spread prize money across the two periods, (ii) how to weigh performance in the two periods when awarding the second-period prize, and (iii) whether to reveal performance after the first period. The information...

A firm can merge with one of n potential partners. The owner of each firm has private information about both his firm's stand-alone value and a component of the synergies that would be realized by the merger involving his firm. We characterize incentive-efficient mechanisms in two cases. First,...

An experimental approach is used to examine the performance of three different multi-unit auction designs: discriminatory, uniform-price with fixed supply, and uniform-price with endogenous supply. We find that the strategies of the individual bidders and the aggregate demand curves are...

We study sequential and single-round uniform-price auctions with affiliated values. We derive symmetric equilibrium for the auction in which k1 objects are sold in the first round and k2 in the second round, with and without revelation of the first-round winning bids. We demonstrate that...
