Also, as the theory predicts, Is increased their bids in the face of greater competition from more Os. 9). The intuition underlying this prediction for our model is as follows: The seller would be unambiguously worse off in the AIS auction relative to the SIS auction if Is in the AIS auction won all the time while bidding according to the prescribed (AIS) equilibrium. However, Is do not win all the time, and when Os win (with their equilibrium bid), they win with relatively high signal values, yielding more revenue than when Is win.
Each of the other bidders, the outsiders (Os), receive a private information signal from a uniform distribution on [xo מε, xo םε], as in the auctions with a symmetric information structure (SIS). The insider does not know the realizations of Os’ private information signals. Os know that they are Os, that there is a single I who knows xo, and the way that all other Os got their private signals. Note that this information structure differs substantially from the “standard” insider information structure in which the insider has a double informational advantage—I knows xo and Os only have access to public information about xo (Engelbrecht-Wiggans, Milgrom, and Weber 1983; Hendricks and Porter 1988).
Signals are drawn from a common uniform distribution with support [x, x]. In the unique symmetric equilibrium of this auction, each bidder bids bi ס2xi, which is implied by equation (4). There is no ex post regret in this symmetric equilibrium, so that even after learning the results of the auction, no bidder wishes to change his bid: When x Ͼ y, the winner is guaranteed a proﬁt (in equilibrium), since she earns x םy and pays only 2y. Further, the loser is guaranteed to lose money if he deviates and bids above 2x, since he would pay 2x and earn only x םy.
