First, we consider the case where agents have to decide to stay for the next round before seeing their valuations for the good. For an arbitrary number of stochastically equivalent objects, we specify the conditions under which ex-ante expected prices are monotonically decreasing. Second, we study an alternative model where agents decide whether to stay for the subsequent round after seeing their valuations for the good. For a two-period model we describe an equilibrium involving a screening level such that only those bidders with values bigger than that amount decide to stay for the last period. We also provide an example where prices are decreasing.","Made available in DSpace on 2014-12-17T22:25:59Z (GMT).
