Horowitz A1 Lori Lynch A1 Andrew Stocking YR 2009 UL http://le.uwpress.org/content/85/4/555.abstract AB Policy makers have turned to competition-based voluntary-enrollment programs as a cost-effective way to achieve preferred land uses. This paper studies bidder behavior in an innovative auction-based program in which farmers compete to sell and retire the right to develop their land. We derive a reduced-form bidding model that includes private and common values. This model allows us to estimate the role of bidder competition, winner’s curse correction, and the underlying distribution of private values. We estimate that the auction enrolled as many as 3,000 acres (12%) more than a take-it-or-leave-it offer would have enrolled for the same budgetary cost. (JEL Q24, Q28)
