In a new setup we introduce non-enforceable sharing rules, as requests, in a repeated redistribution game (called tip pooling). Three experimental treatments differ by the requested amount of sharing of privately known random endowments (tips), with one player never receiving any endowment. Using a hurdle model, we find no significant difference in free riding between the three sharing rules, but strong differences in positive contributions which, however, are lower than the rules prescribe. Furthermore, the average positive contribution remains stable over time, while free riding tends to increase.<\/jats:p>","DOI":"10.3390\/g10030027","type":"journal-article","created":{"date-parts":[[2019,7,1]],"date-time":"2019-07-01T10:54:47Z","timestamp":1561978487000},"page":"27","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["The Power of Requests in a Redistribution Game: An Experimental Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Riccardo","family":"Pedersini","sequence":"first","affiliation":[{"name":"ITCS Abba Ballini, via Tirandi 3, 25128 Brescia, Italy"},{"name":"IIS Luigi Einaudi, via F.lli Sirani 1, 25032 Chiari (BS), Italy"}]},{"given":"Rosemarie","family":"Nagel","sequence":"additional","affiliation":[{"name":"Instituci\u00f3 Catalana de Recerca i Estudis Avan\u00e7ats (ICREA), Passeig de Llu\u00eds Companys, 23, 08010 Barcelona, Spain"},{"name":"Department of Economics, Universitat Pompeu Fabra, Ramon Trias Fargas 25-27, 08005 Barcelona, Spain"}]},{"given":"Marc","family":"Le Menestrel","sequence":"additional","affiliation":[{"name":"Department of Economics, Universitat Pompeu Fabra, Ramon Trias Fargas 25-27, 08005 Barcelona, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,1]]},"reference":[{"key":"ref_1","unstructured":"Zalta, E.N.
