Applying the directional distance-function approach a-la Luenberger (1992) to the production possibility frontier obtained in this fashion can, however, lead to an underestimation of inefficiency for a DMU with relatively large undesirable outputs. This underestimation becomes more acute if the sample size is small or data are clustered. This paper reveals the mechanism behind this underestimation bias, and then quantifies the degree of underestimation using nine-year panel data of rail and aviation sectors in Japan. Through a comparative analysis between parametric and non-parametric methods, we find, among others, that the underestimation of the aviation sector’s productive inefficiency is as large as 80%, which the non-parametric method failed to detect.","subitem_description_type":"Abstract"}]},"item_12_description_8":{"attribute_name":"分野","attribute_value_mlt":[{"subitem_description":"経済学 / Economics","subitem_description_type":"Other"}]},"item_12_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"6619","nameIdentifierScheme":"WEKO"}],"names":[{"name":"山本, 雅資","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"6620","nameIdentifierScheme":"WEKO"}],"names":[{"name":"吉田, 雄一朗","nameLang":"ja"}]}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24545/00001072","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/11-15.html"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ideas.repec.org/p/ngi/dpaper/11-15.html","subitem_relation_type_select":"URI"}}]},"item_12_text_10":{"attribute_name":"発行年","attribute_value_mlt":[{"subitem_text_value":"2011-11"}]},"item_12_text_5":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Asia Pacific School of Logistics, Inha University"},{"subitem_text_value":"富山大学 / University of Toyama"},{"subitem_text_value":"政策研究大学院大学 / National Graduate Institute for Policy Studies"},{"subitem_text_value":"Sauder School of Business, University of British Columbia"}]},"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":"2012-11-28","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"DP11-15","bibliographic_titles":[{"bibliographic_title":"GRIPS Discussion Papers","bibliographic_titleLang":"en"}]}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"HA, Hun Koo","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"YAMAMOTO, Masashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"YOSHIDA, Yuichiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"ZHANG, Anming","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"DP11-15.pdf","filesize":[{"value":"674.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DP11-15.pdf","url":"https://grips.repo.nii.ac.jp/record/1072/files/DP11-15.pdf"},"version_id":"c878feed-dcfa-4a94-a111-72b5417d65de"}]},"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":"Underestimation of Inefficiency in Social Efficiency Benchmarking with Non-Parametric Methods of Production Technology Identification: A Note","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Underestimation of Inefficiency in Social Efficiency Benchmarking with Non-Parametric Methods of Production Technology Identification: A Note","subitem_title_language":"en"}]},"item_type_id":"12","owner":"16","path":["21"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2012-11-28"},"publish_date":"2012-11-28","publish_status":"0","recid":"1072","relation_version_is_last":true,"title":["Underestimation of Inefficiency in Social Efficiency Benchmarking with Non-Parametric Methods of Production Technology Identification: A Note"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-20T08:54:12.534718+00:00"}
