We analyze the general class of symmetric 2&#215;2 games with coupled replicator dynamics in this framework. Standard one- and two-population predictions extend to a total of ten\u00a0 regions with different sets of attractors, among them novel hybrid points where one population randomizes and the other plays a pure strategy. Building on the theoretical analysis, we run continuous-time laboratory experiments using 48 different variants of coupled games. Observations confirm the theory to a large extent, but we also find a number of systematic deviations. When the attractors&#8217; eigenvalues are smaller (in absolute terms), play converges to steady states located further from the prediction.<\/div>\n<\/div>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Volker Benndorf, Ismael Mart\u00ednez-Mart\u00ednez, Hans-Theo Normann, 2021, Journal of Economic Theory, 195, 105281<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[16],"tags":[],"class_list":["post-2814","post","type-post","status-publish","format-standard","hentry","category-publications"],"_links":{"self":[{"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/posts\/2814","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/comments?post=2814"}],"version-history":[{"count":9,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/posts\/2814\/revisions"}],"predecessor-version":[{"id":3073,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/posts\/2814\/revisions\/3073"}],"wp:attachment":[{"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/media?parent=2814"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/categories?post=2814"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/flex.uni-frankfurt.de\/index.php\/wp-json\/wp\/v2\/tags?post=2814"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
