I consider an independent private values auction environment with risk–neutral buyers and an either risk–neutral or risk–averse seller. My setting differs from standard settings in two respects. First, the seller does not know his reservation value at the time he designs the auction, and second, he cannot commit to selling after observing the outcome of the auction. For general distributions of...

Partial resale refers to the business scenario where some resale activities, yet not all, are feasible. A paper by Geng, Wu and Whinston[12] finds that a time-restricted resale market may benefit a ticket seller more than both unrestricted resale and no resale. This paper extends the study on profitable partial resale model in two directions with both theoretical and practical importance. First...
