Empirical Implications of Equilibrium Bidding in First--Price, Symmetric, Common Value Auctions

This paper studies federal auctions for wildcat leases on the Outer Continental Shelf from 1954 to 1970. These are leases where bidders privately acquire (at some cost) noisy, but equally informative, signals about the amount of oil and gas that may be present. We develop tests of rational and equilibrium bidding in a common values model that are implemented using data on bids and "ex post" values. We also use data on tract location and "ex post" values to test the comparative static prediction that bidders may bid less aggressively in common value auctions when they expect more competition. We find that bidders are aware of the "winner"s curse" and their bidding is largely consistent with equilibrium. Copyright The Review of Economic Studies Limited 2003
