The role of training in experimental auctions

In this paper we examine the role of providing extensive training to subjects in the context of experimental auctions. We conducted an experiment where we auctioned several lotteries with varying payoffs. One group of subjects was extensively trained while another group of subjects was only minimally trained. We find that subjects in the extensive training treatment, were submitting bids significantly higher than subjects in the minimal training treatment, suggesting that subjects without proper training may underreport their WTP.
