Each firm has the patent of one of the two old technologies. If each firm produces the product and supplies it without license contract held by another firm, it incurs the compensation for damages in either by use of the new integrated technology developed by it or the existing technology patented by its rival. We show the existence of symmetric Nash equilibria in the game. We also present a necessary and sufficient condition for local stability of the symmetric equilibria. Furthermore, we conduct a comparative statics of the locally stable symmetric Nash equilibria on parameters.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"107896","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tanaka, Satoru"}]},{"nameIdentifiers":[{"nameIdentifier":"107897","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okamura, Makoto"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学社会科学研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00108966","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03873307","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"300","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Institute of Social Science, The University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"神戸市外国語大学"},{"subitem_text_value":"広島大学経済学部"},{"subitem_text_value":"神戸市外国語大学外国語学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中, 悟"}],"nameIdentifiers":[{"nameIdentifier":"107893","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡村, 誠"}],"nameIdentifiers":[{"nameIdentifier":"107894","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"新海, 哲哉"}],"nameIdentifiers":[{"nameIdentifier":"107895","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-26"}],"displaytype":"detail","filename":"KJ00004192013.pdf","filesize":[{"value":"830.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004192013.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17268/files/KJ00004192013.pdf"},"version_id":"e3f71823-4df9-43a9-a47d-200644fdec6f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"補完的技術","subitem_subject_scheme":"Other"},{"subitem_subject":"特許権侵害","subitem_subject_scheme":"Other"},{"subitem_subject":"研究開発投資","subitem_subject_scheme":"Other"},{"subitem_subject":"損害賠償額","subitem_subject_scheme":"Other"},{"subitem_subject":"事前的ライセンス","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"補完的技術革新下での損害賠償額と研究開発インセンティブ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"補完的技術革新下での損害賠償額と研究開発インセンティブ"}]},"item_type_id":"4","owner":"1","path":["976","977"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-09-19"},"publish_date":"2008-09-19","publish_status":"0","recid":"17268","relation_version_is_last":true,"title":["補完的技術革新下での損害賠償額と研究開発インセンティブ"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:57.497296+00:00"}
