Overbidding

Yannai Gonczarowski and Sergiu Hart



Abstract

Consider monopolistic pricing with a single buyer. We show that, when there are multiple goods, it may be (ex post) profitable for the buyer to overbid, i.e., bid according to higher valuations. We consider two main scenarios: strategic overbidding, whereby the buyer's valuation is unchanged, and costly overbidding, whereby the valuation increases and the buyer pays in full the change in his valuation. We further show that overbidding may be profitable not only for the buyer but also for the seller and for the market, increasing revenue, decreasing inefficiency, and reducing prices.
