To consider relationships in the modern society, neither one-shot games nor repeated games are appropriatemodelsbecausethe formationand dissolutionofa relationship is not an option. We formulate voluntarily separable repeated games, in which playersarerandomlymatchedtoplay acomponentgameaswellastochoose whether to play the game again with the same partner. There is no information ?ow across matches, and players areboundedly rational. We extend the notion of Neutrally Stable Distribution (NSD) to ?t for our model. When the component game is a prisoner's dilemma, NSD requires some trust-building periods to defect at the beginning of a partnership. We ?nd that polymorphic NSDs with voluntary breakups include strategies with shorter trust-building periods than any monomorphic NSD with no voluntary separation, and hence the average payo? ofpolymorphic NSD is higher.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"本文フィルはリンク先を参照のこと","subitem_description_type":"Other"}]},"item_8_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本経済国際共同センター"}]},"item_8_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.cirje.e.u-tokyo.ac.jp/research/dp/2006/2006cf415ab.html","subitem_relation_type_select":"URI"}}]},"item_8_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11450569","subitem_source_identifier_type":"NCID"}]},"item_8_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"330","subitem_subject_scheme":"NDC"}]},"item_8_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Center for International Research on the Japanese Economy"}]},"item_8_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Keio University"},{"subitem_text_value":"Norwegian School of Management BI"},{"subitem_text_value":"University of Tokyo"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Fujiwara-Greve, Takako"}],"nameIdentifiers":[{"nameIdentifier":"97669","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okuno-Fujiwara, Masahiro"}],"nameIdentifiers":[{"nameIdentifier":"97670","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"voluntary separation","subitem_subject_scheme":"Other"},{"subitem_subject":"prisoner's dilemma","subitem_subject_scheme":"Other"},{"subitem_subject":"evolution","subitem_subject_scheme":"Other"},{"subitem_subject":"trust","subitem_subject_scheme":"Other"},{"subitem_subject":"JEL Classification Numbers: C73","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Voluntarily Separable Prisoner's Dilemma","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Voluntarily Separable Prisoner's Dilemma"}]},"item_type_id":"8","owner":"1","path":["7436","7434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-03"},"publish_date":"2013-06-03","publish_status":"0","recid":"42432","relation_version_is_last":true,"title":["Voluntarily Separable Prisoner's Dilemma"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:17:37.713392+00:00"}
