In this note we examine four standard multi-unit sealed-bid auctions in the presence of synergy. The structure of the equilibrium bidding strategy under each rule is quite intuitive. Whether the equilibrium involves "bundle-bidding" or "separating-bidding" strategy depends on the presence of the...

There are a number of examples in the auction literature (Perry and Reny, 1999, and Krishna, 2002) where releasing the seller's private information can lead to a lowering of expected revenue. On the other hand, releasing information always increases welfare. Levin and Smith (1994) point out that...

In a bargaining model with dependent private information, I extend the result on existence of efficient mechanisms allowing any distribution of the surplus among traders. This generalization introduces flexibility into the model since full surplus extraction by one trader is incompatible with ex...
