Although it's importance in the Japanese merger policy, it has been almost reviewed only in a stereotyped manner. In this article, the author analyzes the concept of \"\"effective competitors\"\" from several points, i.e. the legislative history of Antimonopoly Act, judgments of courts, decisions and guidelines issued by Fair Trade Commission of Japan (JFTC), economic theory, and comparative law (especially, US Antitrust Law). The competitive pressure by the properly defined \"\"effective competitors\"\" can prevent merging undertakings from exploiting market power. This article articulates that how \"\"effective competitors\"\" should be defined and identified. Then, it analyzes Japan Airlines and Japan Airsystem Business Consolidation Case (2002) which is the most controversial in recent JFTC prior consultation cases.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"107918","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hayashi, Shuya"}]}]},"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:公正取引委員会競争政策研究センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"林, 秀弥"}],"nameIdentifiers":[{"nameIdentifier":"107917","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":"KJ00004192022.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004192022.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17277/files/KJ00004192022.pdf"},"version_id":"76201c0c-79d9-42f9-81fb-af208a6ea456"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"有効な牽制力がある競争者","subitem_subject_scheme":"Other"},{"subitem_subject":"インセンティブ","subitem_subject_scheme":"Other"},{"subitem_subject":"能力","subitem_subject_scheme":"Other"},{"subitem_subject":"一定の取引分野における競争の実質的制限","subitem_subject_scheme":"Other"},{"subitem_subject":"独占禁止法上の企業結合規制","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":"企業結合の違法性判断における「有効な牽制力のある競争者」の位置づけ : 独禁法の一大議論の一断面","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"企業結合の違法性判断における「有効な牽制力のある競争者」の位置づけ : 独禁法の一大議論の一断面"}]},"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":"17277","relation_version_is_last":true,"title":["企業結合の違法性判断における「有効な牽制力のある競争者」の位置づけ : 独禁法の一大議論の一断面"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:57.390170+00:00"}
