We study the optimal auction design problem when bidders' preferences follow the maxmin expected utility model. We suppose that the bidders' set of priors consists of beliefs "close" to the seller's belief, where "closeness" is defined by a divergence. For a given allocation rule, we identify a...

We study the revenue comparison problem of auctions when the seller has a maxmin expected utility preference. The seller holds a set of priors around some reference belief, interpreted as an approximating model of the true probability law or the focal point distribution. We develop a methodology...

Some philosophers and social scientists have stressed the importance for good government of an altruistic citizenry that values the well being of one another. Others have emphasized the need for incentives that induce even the self interested to contribute to the public good. Implicitly most...
