We review previous Cournot experiments in the literature. Additionally, we conduct a new series of experiments studying oligopolies with two, three, four, and five firms in a unified frame. With two firms we find some collusion. Three-firm oligopolies tend to produce outputs at the Nash level. Markets with four or five firms are never collusive and typically settle at or above the Cournot outcome. Some of those markets are actually quite competitive with outputs close to the Walrasian outcome.GermanyGermanyStudentsHuck, Steffen; Normann, Hans-Theo; Oechssler, Jörg, "Two are Few and Four are Many: Number Effects in Experimental Oligopoly", Journal of Economic Behavior and Organization 53 (2004), 435-446.10.1016/j.jebo.2002.10.002Huck, Steffen; Normann, Hans-Theo; Oechssler, Jörg, "Two are Few and Four are Many: Number Effects in Experimental Oligopoly", Journal of Economic Behavior and Organization 53 (2004), 435-446.data two are few.tab62924text/tab-separated-valuesUNF:5:ZO79Xsj/X7piQu3p8pQheg==TREATMUNF:5:6hkaAtRiAJ8n0rI0Rs7ZfA==PERIODUNF:5:ixkOfX6SFtzcFMJcks0ddA==GROUPUNF:5:/0pxrEZA/JAaYS5VCmPk0g==Q1UNF:5:wWJ2ydKmxd6KrSsjlAoqqQ==Q2UNF:5:tWdLkYQaj8R+VqFgwLrJ6w==Q3UNF:5:sNy1y4kLBkDQ54azWK8yDg==Q4UNF:5:oayqtBscrPcoMQR1TfMwKw==Q5UNF:5:EwzLOqHMjZY1OjOwNlKBDg==total quantityUNF:5:Q6nLjYCe2ASA4C+x2ozGtw==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==UNF:5:5sVluCv16iuG3A0FBh+jWQ==data two are few.xlsxOpenXML - Spreadsheet formatapplication/octet-streamLZA.tar.gzThis file is for internal use only.application/x-gzip
