A simplified mechanism is a direct mechanism modified by restricting the set of reports or bids. An example is the auction used to place ads on Internet search pages, in which each advertiser bids a single price to determine the allocation of eight or more ad positions on a page. If a simplified...

A common pattern of control in firms is for management to retain a broad set of rights, while the remaining stakeholders’ contracts provide them with targeted veto rights over specific classes of decisions. We explain this pattern of control sharing as an efficient organizational response that...

We describe factors that make bidding in large spectrum auctions complex including exposure and budget problems, the role of timing within an ascending auction, and the possibilities for price forecasting and how economic and game-theoretic analysis can assist bidders in overcoming these...

A mechanism can be simplified by restricting its message space. If the restricted message space satisfies a certain “outcome closure property,” then the simplification is “tight”: for every S=0 any Nash equilibrium of the simplified mechanism is also an Nash equilibrium of the...

We propose the clock-proxy auction as a practical means for auctioning many related items. A clock auction phase is followed by a last-and-final proxy round. The approach combines the simple and transparent price discovery of the clock auction with the efficiency of the proxy auction. Linear...

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...
