SILENT AUCTIONS IN THE FIELD AND IN THE LABORATORY.

We analyze data from hundreds of auctions from three field silent auction sessions. We focus on the descriptive statistics and on a parametric model of jump bidding. We then report data from six laboratory sessions of silent auctions. As a controlled environment, this allows us to evaluate the auctions in ways not available within the field. The laboratory experiments capture essential features of the field sessions and thus comprise a credible laboratory testbed for further examination of institutional perturbations in the silent auction.
