Sequential auctions for objects with common and private values
Sequential auctions are an important mechanism for buying/selling multiple objects. Existing work has studied sequential auctions for objects that are exclusively either common value or private value. However, in many real-world cases an object has both features. Also, in such cases, the common value component (which is the same for all bidders) depends on how much each bidder values the object. Moreover, an individual bidder generally does not know the true common value, since it may not know how much the other bidders value it. On the other hand, a bidder’s private value is independent of the others’ private values. Given this, we study settings that have both common and private value elements by treating each bidder’s information about the common value as uncertain. We first determine equilibrium bidding strategies for each auction in a sequence using English auction rules. On the basis of this equilibrium, we analyse the efficiency of auctions. Specifically, we show that ...
