چکیده

We show that in large symmetric auctions with conditionally i.i.d. common values and CARA preferences, the second-price auction raises more revenue than the …rst-price auction. We also show by an example that the ranking does not extend to general symmetric risk-averse preferences.

Large auctions with risk-averse bidders

We study private-value auctions with n risk-averse bidders, where n is large. We first use asymptotic analysis techniques to calculate explicit approximations of the equilibriumbids and of the seller’s revenue in any k-price auction (k = 1, 2, . . .). These explicit approximations show that in all large k-price auctions the effect of risk-aversion is O(1/n2) small. Hence, all large k-price auct...

Precautionary Bidding in Auctions

We analyze bidding behavior in auctions when risk-averse buyers bid for a good whose value is risky. We show that when the risk in the valuations increases, DARA bidders will reduce their bids by more than the appropriate increase in the risk premium. Ceteris paribus, buyers will be better off bidding for a more risky object in first price, second price, and English auctions with affiliated com...

Auction Selection by an Informed Seller

We analyze selection of an auction format by an informed seller. We model a game with two stages: first, an informed seller announces a good for sale and chooses an auction format from a set of standard auctions; second, privately informed bidders compete for the object. The game has an important signaling element as the auction choice may signal the seller’s type. We study both private and com...

Risk aversion and loss aversion in core-selecting auctions

Core-selecting combinatorial auctions have been introduced as an alternative to the Vickrey-Clarke-Groves (VCG) mechanism because VCG results in payments that are not in the core with respect to bids, leading to unfair payments, unacceptably low revenues, and unstable outcomes. This raises an auction selection problem for an auctioneer deciding whether to employ a core-selecting auction or VCG ...

Revenue comparisons for auctions when bidders have arbitrary types

This paper develops a methodology for characterizing expected revenue from auctions when bidders’ types come from an arbitrary distribution. In particular, types may be multidimensional, and there may be mass points in the distribution. One application extends existing revenue equivalence results. Another application shows that first-price auctions yield higher expected revenue than second-pric...
