We formulate a model of voluntary repetition by introducing outside　options to a repeated Prisoner’s Dilemma and investigate how the structure of outside options affects the sustainability of mutual cooperation. When the outside　option is deterministic and greater than the value of mutual defection, the lower bound of the discount factors that sustain repeated cooperation is greater than the　one for ordinary repeated Prisoner’s Dilemma, making cooperation more difficult. However,stochastic outside options with the same mean may reduce the lower　bound of discount factors as compared to the deterministic case. This is possible when the stochasticity of the options increases the value of the cooperation phase　more than the value of the punishment phase. Necessary and sufficient conditions for this positive effect are given under various option structures.","subitem_description_type":"Abstract"}]},"item_12_description_7":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"JEL Classification Codes: C73","subitem_description_type":"Other"}]},"item_12_description_8":{"attribute_name":"分野","attribute_value_mlt":[{"subitem_description":"経済学 / Economics","subitem_description_type":"Other"}]},"item_12_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6317","nameIdentifierScheme":"WEKO"}],"names":[{"name":"安田, 洋祐","nameLang":"ja"}]}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24545/00001010","subitem_identifier_reg_type":"JaLC"}]},"item_12_publisher_12":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"GRIPS Policy Research Center ","subitem_publisher_language":"en"}]},"item_12_relation_16":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://ideas.repec.org/p/ngi/dpaper/09-10.html"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ideas.repec.org/p/ngi/dpaper/09-10.html","subitem_relation_type_select":"URI"}}]},"item_12_text_10":{"attribute_name":"発行年","attribute_value_mlt":[{"subitem_text_value":"2009-06"}]},"item_12_text_5":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Economics, Keio University"},{"subitem_text_value":"政策研究大学院大学 / National Graduate Institute for Policy Studies"}]},"item_12_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_1693541285410":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"2009-07-01","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"DP09-10","bibliographic_titles":[{"bibliographic_title":"GRIPS Discussion Papers","bibliographic_titleLang":"en"}]}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"FUJIWARA-GREVE, Takako","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YASUDA, Yosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"DP09-10.pdf","filesize":[{"value":"442.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DP09-10.pdf","url":"https://grips.repo.nii.ac.jp/record/1010/files/DP09-10.pdf"},"version_id":"1a60e8d9-a12c-45c9-b49f-aa41bb288000"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"outside option","subitem_subject_scheme":"Other"},{"subitem_subject":"repeated Prisoner’s Dilemma","subitem_subject_scheme":"Other"},{"subitem_subject":"cooperation","subitem_subject_scheme":"Other"},{"subitem_subject":"perturbation","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"}]},"item_title":"Cooperation in Repeated Prisoner’s Dilemma with Outside Options","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cooperation in Repeated Prisoner’s Dilemma with Outside Options","subitem_title_language":"en"}]},"item_type_id":"12","owner":"16","path":["19"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-07-01"},"publish_date":"2009-07-01","publish_status":"0","recid":"1010","relation_version_is_last":true,"title":["Cooperation in Repeated Prisoner’s Dilemma with Outside Options"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-20T08:55:12.815691+00:00"}
