The English auction is susceptible to tacit collusion when post-auction interbidderresale is allowed. We show this by constructing equilibria where, withpositive probability, one bidder wins the auction without any competition anddivides the spoils by optimally reselling the good to the other...

In standard auctions with symmetric, independent private value bidders resale creates a role for a speculator - a bidder who is commonly known to have no use value for the good on sale. For second-price and English auctions the efficient value-bidding equilibrium coexists with a continuum of...

We consider 2-bidder first-price auctions where one bidder's value is commonly known. Such auctions induce an ineffcient allocation. We show that a resale opportunity, where the auction winner can make a take-it-or-leave-it offer to the loser, increases (reduces) the ineffciency of the market...

Zheng has recently proposed a seller-optimal auction for (asymmetric) independentprivate- value environments where inter-bidder resale is possible. Zheng's construction requires novel conditions on the bidders' value distribution profile. We clarify the restrictions implied by these conditions....
