We address the issue of bidder ring formation in single and multi-unit Vickrey auctions. We address this issue in a bargaining game set up under the assumption that valuation of bidders is commonly known only amongst themselves. In the single unit case, we show that the equilibrium coalition...

We determine the equilibrium in two transaction mechanisms: auctions and posted prices. Agents choose whether to participate in markets where trades are consummated by auctions or in markets where sellers post prices. We show that the selling mechanisms are practically equivalent. Previous...

A proposed auction design for incentive auctions is given. The two-sided auctions enable the exchange of spectrum from a low-value use, such as over-the-air TV broadcast, to a high-value use, such as mobile broadband. The approach is both simple and effective. The auction has three stages...

We study auction design in the standard symmetric independent private values environment, where the seller lacks the commitment power to withhold an unsold object off the market. The seller has a single object and can conduct an infinite sequence of standard auctions with reserve prices to...

In a market where sellers compete by posting trading mechanisms, we allow for a general search technology and show that its features crucially affect the equilibrium mechanism. Price posting prevails when meetings are rival, i.e., when a meeting by one buyer reduces another buyer's meeting...

The best sites for offshore wind farms on the US Outer Continental Shelf are scarce. To make the best use of this scarce resource, it is necessary to implement a fair and efficient mechanism to assign wind rights to companies that are most likely to develop off-shore wind energy projects....

The present invention primarily concerns hybrid auctions that may, for example, combine a clock auction with a proxy auction. Hybrid auctions include multi-item auctions that comprise at least two phases of package auctions: an earlier phase in which bidders participate in a clock auction (or...

In the original proposal for the combinatorial clock auction (Ausubel, Cramton and Milgrom, 2006), a revealed-preference approach was taken to limiting bidders’ activity, based on their earlier activity. However, empirical implementations of the CCA to spectrum auctions have tended to place...

We examine bidding behavior in a clock auction in which price is set by the lowest-accepted bid and provisional winners are reported each round (the LABpw auction). This format was used in the India 3G spectrum auction. In the standard theory, the auction performs poorly. In particular it yields...
