We show that any such game based on an IIA demand system admits an ordinal potential, giving rise to a simple proof of equilibrium existence. We introduce the concept of transformed potential, and characterize the class of demand systems that give rise to multiproduct-firm pricing games admitting such a potential, as well as the associated transformation functions. The resulting demand systems allow for substitutability or complementarity patterns that go beyond IIA, and can resemble those induced by &#8220;one-stop shopping&#8221; behavior.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>The paper Nicolas will present is below in case you want to have a look at it in advance.<\/p>\n<p><a href=\"https:\/\/i3.cnrs.fr\/wp-content\/uploads\/2025\/04\/NS-OCTraPot-CRC-DP-Jan2025.pdf\">Paper of\u00a0 Nicolas Schutz-Jan2025<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Oligopoly, Complementarities, and Transformed Potentials<\/p>\n","protected":false},"author":9,"featured_media":0,"template":"","meta":{"_acf_changed":false,"_tribe_events_status":"","_tribe_events_status_reason":"","footnotes":""},"tags":[],"tribe_events_cat":[160],"class_list":["post-20407","tribe_events","type-tribe_events","status-publish","hentry","tribe_events_cat-seminaires-en","cat_seminaires-en","entry"],"acf":[],"_links":{"self":[{"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/20407","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events"}],"about":[{"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/types\/tribe_events"}],"author":[{"embeddable":true,"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/users\/9"}],"version-history":[{"count":0,"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events\/20407\/revisions"}],"wp:attachment":[{"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/media?parent=20407"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/tags?post=20407"},{"taxonomy":"tribe_events_cat","embeddable":true,"href":"https:\/\/i3-cnrs.fr\/en\/wp-json\/wp\/v2\/tribe_events_cat?post=20407"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
