A common assumption in the analysis of symmetric auctions is that the bidders' value estimates exhibit positive informational externalities (PIE). This assumption implies upward drifting price sequences at sequential auctions, which is challenged by an empirical regularity, known as the...

This paper explores a multiple-object auction with the following three features: First, there is a capacity constraint, as each bidder can win at most one object from the auction. Second, the objects for sale and the bidders are located around the unit circle. A bidder's valuation of a certain...

Should an informed seller of multiple goods sell the best goods first to make a favorable impression on buyers, or instead hold back on the best goods until buyers have learned more from earlier sales? To help answer this question we consider the sequential auction of two goods by a seller with...

We analyze sequential Dutch and Vickrey auctions where risk averse, or risk preferring, bidders may have heterogeneous risk exposures. We derive and characterize a pure strategy equilibrium of both auctions for arbitrary number of identical objects. A sufficient, and to certain extent necessary,...
