Spectrum auctions are used by governments to assign and price licenses for wireless communications. The standard approach is the simultaneous ascending auction, in which many related lots are auctioned simultaneously in a sequence of rounds. I analyze the strengths and weaknesses of the approach...

In a mechanism design problem, participation constraints require that all types prefer the proposed mechanism to some status quo. If equilibrium play in the status quo mechanism depends on the players' beliefs, then the inference drawn if someone objects to the proposed mechanism may alter the...

The high-frequency trading arms race is a symptom of flawed market design. Instead of the continuous limit order book (CLOB) that is currently predominant, we argue that financial exchanges should use frequent batch auctions: uniform price double auctions conducted, e.g., every tenth of a...

Since their advent in 2001, virtual power plant (VPP) auctions have been implemented widely. In this paper, we describe the simultaneous ascending-clock auction format that has been used for virtually all VPP auctions to date, elaborating on other design choices that most VPP auctions have had...

Our recent research (Budish, Cramton, and Shim 2013) proposes frequent batch auctions—uniform-price sealed-bid double auctions conducted at frequent but discrete time intervals—as a market design alternative to continuous-time trading in financial markets. This short paper discusses the...

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...

On 1 April 2011, 110 stakeholders in the Medicare Durable Medical Equipment (DME) industry came to the University of Maryland to discuss how the CMS’ current competitive bidding program could be improved. The participants included Medicare providers, government leaders, and auction experts. A...

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...
