Evidence suggests that people evaluate outcomes relative to expectations. I analyze this expectation-based loss aversion [Köszegi and Rabin (2006, 2009)] in the context of dynamic and static auctions, where the reference point is given by the (endogenous) equilibrium outcome. If agents update their reference point during the auction, the arrival of information crucially affects equilibrium behavior. Consequently, I show that- even with independent private values|the Vickrey auction yields strictly higher revenue than the English auction, violating the well known revenue equivalence. Thus, dynamic loss aversion o ers a novel explanation for empirically observed differences between these auction formats. |
