We find that the mechanism is still Pareto-improving under endowment heterogeneity, but that its efficiency diminishes as inequality is increased. Our experimental findings indicate a significant weakening of the mechanism under endowment inequalities, surpassing our theoretical predictions. A close examination of individual behaviors reveals a significant drop in contributions compared to the uniform case, prompted by even minor inequalities. Intriguingly, our findings challenge conventional assumptions by showing that inequality aversion drives contributions in a public good game with endowment disparities only under certain assumptions. We explore the impact of beliefs about the contributions of advantaged player as potential motivations through guilt aversion and Kantian preferences.<\/p>\n<h5>\u8b1b\u6f14\u8005 \/ Speaker<\/h5>\n<p><a href=\"https:\/\/www.waseda.jp\/inst\/wias\/other\/2024\/11\/21\/17267\/\">WILLINGER, Marc<\/a> (Professor, University of Montpellier, Center for Environmental Economics of Montpellier (CEE-M))<\/p>\n<h5>\u65e5\u3000\u6642 \/ Date &amp; Time<\/h5>\n<p>2024\u5e7411\u670822\u65e5\uff08\u91d1\uff0917:00 &#8211; 18:30 \/ Nov 22, 2024 (Fri.) 17:00 &#8211; 18:30<\/p>\n<h5>\u4f1a\u3000\u5834 \/ Venue<\/h5>\n<p>\u65e9\u7a32\u7530\u5927\u5b66\u3000\u65e9\u7a32\u7530\u30ad\u30e3\u30f3\u30d1\u30b9 3\u53f7\u9928 \u3000909\u53f7\u5ba4<br \/>\nBuilding#3\u00a0 Room#909,\u00a0 Waseda Campus, Waseda University<\/p>\n<h5 style=\"text-align: justify;\">\u8a00\u3000\u8a9e \/ Language<\/h5>\n<p>\u82f1\u8a9e \/ English<\/p>\n<h5>\u5bfe\u3000\u8c61 \/ Prospected Audience<\/h5>\n<p>\u5b66\u751f\u30fb\u7814\u7a76\u8005\u30fb\u6559\u8077\u54e1\u30fb\u4e00\u822c \/ Undergraduate, Graduate, Researchers, Faculty members, general audience<\/p>\n<h5>\u4e3b\u3000\u50ac \/ Organizer<\/h5>\n<p>\u65e9\u7a32\u7530\u5927\u5b66\u73fe\u4ee3\u653f\u6cbb\u7d4c\u6e08\u7814\u7a76\u6240\u8239\u6728\u90e8\u4f1a\u7814\u7a76\u4f1a<\/p>\n<h5>\u5171\u3000\u50ac \/ Co-organizer<\/h5>\n<p>\u65e9\u7a32\u7530\u5927\u5b66\u9ad8\u7b49\u7814\u7a76\u6240 \/ Waseda Institute for Advanced Studies (WIAS)<\/p>\n<h5>\u7533\u3057\u8fbc\u307f \/ Registration<\/h5>\n<p>\u4e8b\u524d\u4e88\u7d04\u4e0d\u8981<br \/>\nRegistration is not required to participate.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u9ad8\u7b49\u7814\u7a76\u6240 \u8a2a\u554f\u7814\u7a76\u54e1 \u30bb\u30df\u30ca\u30fc: Efficiency of the Minimum Approval Mechanism with heterogeneous players\uff0811\/22\uff09 \u8a73\u3000\u7d30\/ Details  [&hellip;]<\/p>\n","protected":false},"author":6,"featured_media":17310,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[24,26,28],"class_list":["post-17217","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","tag-events","tag-general","tag-research"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17217","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/comments?post=17217"}],"version-history":[{"count":2,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17217\/revisions"}],"predecessor-version":[{"id":17303,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/posts\/17217\/revisions\/17303"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/media\/17310"}],"wp:attachment":[{"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/media?parent=17217"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/categories?post=17217"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.waseda.jp\/inst\/wias\/wp-json\/wp\/v2\/tags?post=17217"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
