In auctions with externalities, the core can be empty, which is undesirable both in terms of stability and fairness. We … show that the core is nonempty if the seller cannot deviate, as a counterpart of the result of the nonemptiness of the core …

In auctions with externalities, it is well-known that the core can be empty, which is undesirable both in terms of … the sense that the seller and the bidders experience justified envy. We show that the core is nonempty if bidders cannot …
