In Savage\u2019s model the probability-utility pair is associated with preferences over acts which are assignments of consequences to states. The probability is defined on the state space, and the utility function on consequences. Jeffrey\u2019s model has no consequences, and both probability and utility are defined on the same set of propositions. The probability-utility pair is associated with a desirability relation on propositions. Like Savage we assume a set of consequences and a state space. However, we assume that states are comprehensive, that is, each state describes a consequence, as in Aumann (1987). Like Jeffrey, we assume that the agent has a preference relation, which we call desirability, over events, which by definition involves uncertainty about consequences. For a given probability and utility of consequences, the desirability relation is presented by conditional expected utility, given an event. We axiomatically characterize desirability relations that are represented by a probability-utility pair. We characterize the family of all the probability-utility pairs that represent a given desirability relation.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dov Samet from the Coller School of Management at Tel Aviv University will be presenting his paper &#8220;Desirability&#8221; on October 4th at 10 AM, room QA405.\u00a0One-to-one meetings with the speaker can be arranged; please contact the seminar organizers, Dr. No\u00e9mie Cabau (cabau.noemie@gtk.bme.hu) and Dr. Arseniy Samsonov (samsonov.arseniy@gtk.bme.hu).\u00a0\u00a0 Abstract:&nbsp;&nbsp;We propose a model of an agent\u2019s probability &hellip; <a href=\"https:\/\/qsms.bme.hu\/index.php\/2022\/10\/03\/october-4-dov-samet-qsms-seminar\/\" class=\"more-link\">Continue reading<span class=\"screen-reader-text\"> &#8220;October 4: Dov Samet (QSMS Seminar)&#8221;<\/span><\/a><\/p>\n","protected":false},"author":12,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22,4,17],"tags":[],"class_list":["post-1399","post","type-post","status-publish","format-standard","hentry","category-event","category-news","category-seminar"],"_links":{"self":[{"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/posts\/1399","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/users\/12"}],"replies":[{"embeddable":true,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/comments?post=1399"}],"version-history":[{"count":4,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/posts\/1399\/revisions"}],"predecessor-version":[{"id":1404,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/posts\/1399\/revisions\/1404"}],"wp:attachment":[{"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/media?parent=1399"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/categories?post=1399"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/qsms.bme.hu\/index.php\/wp-json\/wp\/v2\/tags?post=1399"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
