We compare the expected revenue in first- and second-price auctions with asymmetric bidders. We consider “close to uniform” distributions with identical supports and show that in the case of identical supports the expected revenue in second-price auctions may exceed that in first-price...

We study private-value auctions with a large number of bidders. We calculate approximations of the equilibrium bids and the seller's revenue in first-price auctions regardless of whether the bidders are symmetric or asymmetric, or risk-neutral or risk-averse. Furthermore, we show that...
