It implies that the DEA efficiency score without data adjustment might be biased and impractical for measuring genuine management efficiency. Therefore it is essential to eliminate uncontrollable effects from DEA scores and evaluate “pure” managerial efficiency for DMUs. In an effort to solve this problem, we employ a multi-stage data adjustment procedure using DEA and regression models, which is originally proposed by Fried et al. [1999] consisting of four stages. In this study, we further modify this procedure by introducing newly developed devices in each stage; Connected Slacks-Based Measure (CSBM) model at the first and fourth stages, the Tobit model with DMU dummies at the second stage, and a data tuning procedure at the third stage. Then we decompose the technical inefficiency into three factors, i.e. environmental effects, time shift effects and pure technical inefficiency. Lastly, we apply this procedure to the electric power utilities in Japan and the US and compare their pure technical efficiency and causes of inefficiency.","subitem_description_type":"Abstract"}]},"item_12_description_8":{"attribute_name":"分野","attribute_value_mlt":[{"subitem_description":"総合政策 / Multi Disciplinary policy studies","subitem_description_type":"Other"}]},"item_12_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6141","nameIdentifierScheme":"WEKO"}],"names":[{"name":"筒井, 美樹","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"6142","nameIdentifierScheme":"WEKO"}],"names":[{"name":"刀根, 薫","nameLang":"ja"}]}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24545/00000979","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/07-09.html"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ideas.repec.org/p/ngi/dpaper/07-09.html","subitem_relation_type_select":"URI"}}]},"item_12_text_10":{"attribute_name":"発行年","attribute_value_mlt":[{"subitem_text_value":"2007-12"}]},"item_12_text_5":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"電力中央研究所 / Central Research Institute of Electric Power Industry"},{"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":"2007-12-01","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"DP07-09","bibliographic_titles":[{"bibliographic_title":"GRIPS Discussion Papers","bibliographic_titleLang":"en"}]}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TSUTSUI, Miki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TONE, Kaoru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"DP07-09.pdf","filesize":[{"value":"235.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DP07-09.pdf","url":"https://grips.repo.nii.ac.jp/record/979/files/DP07-09.pdf"},"version_id":"fc688180-a3c0-4dfe-9e6c-a9a84ce9ab7c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"data envelopment analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"data adjustment","subitem_subject_scheme":"Other"},{"subitem_subject":"electric utilities","subitem_subject_scheme":"Other"},{"subitem_subject":"multi-stage model","subitem_subject_scheme":"Other"},{"subitem_subject":"decomposition","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":"Separation of uncontrollable factors and time shift effects from DEA scores","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Separation of uncontrollable factors and time shift effects from DEA scores","subitem_title_language":"en"}]},"item_type_id":"12","owner":"16","path":["16"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-12-01"},"publish_date":"2007-12-01","publish_status":"0","recid":"979","relation_version_is_last":true,"title":["Separation of uncontrollable factors and time shift effects from DEA scores"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-20T08:56:43.648334+00:00"}
