"Revenue Neutral Assignment Auctions: An Experiment" which is joint with David Porter (Chapman University).  

"Traditional solutions to the assignment problem are less than ideal in high contention environments. When preferences are similar but vary in magnitude, market clearing prices may be high and random serial dictatorship may be inefficient. In this paper, we explore the efficiency and welfare properties of several alternative mechanisms. In some treatments, participants are endowed with an allotment of non-monetary tokens to bid with in place of money. In other treatments, auction revenues are returned via cash rebate. We study both open outcry and sealed bid auctions when token budgets are fixed and when participants can buy and sell tokens in a pre-market."
