Experience Weighted Attraction in the First Price Auction and Becker Degroot Marschak

In this paper we explore the performance of Experience Weighted Attraction (EWA) in two different auction institutions: First Price Sealed Bid, and Becker-DeGroot-Marschak. Our results suggest that learning has some promise as a possible explanation for previously documented cross- institutional choice anomalies usually attributed to risk aversion. Additionally, we present results on the likely econometric (ir)recoverability of EWA parameters in these institutions.
