In this period, while Mitsubishi Holdings rapidly expanded the total investment in securities, it substantially changed the portfolio, increasing investment in the companies in the munitions industry. This portfolio management policy was not successful in terms of profitability. We decomposed the profitability decline into that due to the declines in the returns on the individual securities which had existed in the portfolio and that due to the change in the portfolio. We found that whereas the former factor was larger, the portfolio factor was also substantial. This result suggests that the asset management system of Mitsubishi Holdings came not to work well, which in turn would be due to government intervention and deterioration of the governance within Mitsubishi Zaibatsu.","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_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"97527","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okazaki, Tetsuji"}]}]},"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/2006/2006cj170ab.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":"AA11451834","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":"東京大学大学院経済学研究科"}]},"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":"岡崎, 哲二"}],"nameIdentifiers":[{"nameIdentifier":"97526","nameIdentifierScheme":"WEKO"}]}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"戦時期における三菱財閥本社の有価証券ポートフォリオ管理と投資収益率 : 1935－44年度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"戦時期における三菱財閥本社の有価証券ポートフォリオ管理と投資収益率 : 1935－44年度"}]},"item_type_id":"8","owner":"1","path":["7436","7437"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-06-03"},"publish_date":"2013-06-03","publish_status":"0","recid":"42358","relation_version_is_last":true,"title":["戦時期における三菱財閥本社の有価証券ポートフォリオ管理と投資収益率 : 1935－44年度"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:17:34.426500+00:00"}
