Anderson and Neven (1991)の均衡分析では企業は中央に集積するが,ここでは市場規模と企業が支払わなければならない単位輸送費の比が十分小さければ,企業はちょうど2つの点で対称部分集積を起こすことが示された.中央集積は逆にその比が大きければ成立する.社会的な視点から見ると,前者のケースでは,企業が部分集積の際に中央から離れようとする私的な誘因を過大に持つ.また,企業数が増えることにより,企業が均衡では2点に立地するにもかかわらず,中央集積が社会厚生を改善できるようなパラメータ範囲が広くなることを示した.","subitem_description_type":"Abstract"},{"subitem_description":"Partial collusion in spatial Cournot competition is analyzed. In a linear-city setting, multiple firms collusively decide their locations in the first stage and non-collusively compete in a Cournot fashion in the second stage. We find that unlike in Anderson and Neven (1991) where firms always centrally agglomerate in a competitive equilibrium, firms tend to locate at exactly two locations when the ratio of market size to the unit transport cost firms face is sufficiently low. The central agglomeration result remains when this ratio is high. From the social viewpoint, the private incentive for separation is excessive in the former case. As the number of firms increases, the parameter range increases where firms prefer to locate at two places but central agglomeration results in a higher welfare level.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"107916","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Shimizu, Daisuke"}]}]},"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":"東京大学大学院経済学研究科"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"清水, 大昌"}],"nameIdentifiers":[{"nameIdentifier":"107915","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":"KJ00004192021.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004192021.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17276/files/KJ00004192021.pdf"},"version_id":"6df1636f-48ce-43be-a7af-459f9625abdc"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"立地競争","subitem_subject_scheme":"Other"},{"subitem_subject":"数量競争","subitem_subject_scheme":"Other"},{"subitem_subject":"部分結託","subitem_subject_scheme":"Other"},{"subitem_subject":"線形都市","subitem_subject_scheme":"Other"},{"subitem_subject":"企業輸送モデル","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":"立地-数量競争モデルにおける立地結託について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"立地-数量競争モデルにおける立地結託について"}]},"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":"17276","relation_version_is_last":true,"title":["立地-数量競争モデルにおける立地結託について"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:56:02.379621+00:00"}
