The sharp RD estimator requires to estimate two conditional mean functions on the left and the right of the cut-off point nonparametrically. We propose to choose two bandwidths, one for each side for the cut-off point, simultaneously in contrast to common single-bandwidth approaches. We show that allowing distinct bandwidths leads to a nonstandard minimization problem of the asymptotic mean square error. To address this problem, we theoretically define and construct estimators of the asymptotically first-order optimal bandwidths that exploit the second-order bias term. The proposed bandwidths contribute to reduce the mean squared error mainly due to their superior bias performance. A simulation study based on designs motivated by existing empirical literatures exhibits a significant gain of the proposed method under the situations where single-bandwidth approaches can become quite misleading.","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":"6790","nameIdentifierScheme":"WEKO"}],"names":[{"name":"荒井, 洋一","nameLang":"ja"}]},{"nameIdentifiers":[{"nameIdentifier":"6791","nameIdentifierScheme":"WEKO"}],"names":[{"name":"市村, 英彦","nameLang":"ja"}]}]},"item_12_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24545/00001139","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/14-03.html"}],"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://ideas.repec.org/p/ngi/dpaper/14-03.html","subitem_relation_type_select":"URI"}}]},"item_12_text_10":{"attribute_name":"発行年","attribute_value_mlt":[{"subitem_text_value":"2014-04"}]},"item_12_text_5":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"政策研究大学院大学 / National Graduate Institute for Policy Studies"},{"subitem_text_value":"東京大学 / Department of Economics, The University of Tokyo"}]},"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":"2014-04-01","bibliographicIssueDateType":"Issued"},"bibliographicVolumeNumber":"DP14-03","bibliographic_titles":[{"bibliographic_title":"GRIPS Discussion Papers","bibliographic_titleLang":"en"}]}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"ARAI, Yoichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ICHIMURA, Hidehiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"DP14-03.pdf","filesize":[{"value":"260.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DP14-03.pdf","url":"https://grips.repo.nii.ac.jp/record/1139/files/DP14-03.pdf"},"version_id":"5045f037-7863-473f-8c95-74ac0b8cef7f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Bandwidth selection","subitem_subject_scheme":"Other"},{"subitem_subject":"local linear regression","subitem_subject_scheme":"Other"},{"subitem_subject":"regression discontinuity design","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":"Simultaneous Selection of Optimal Bandwidths for the Sharp Regression Discontinuity Estimator","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Simultaneous Selection of Optimal Bandwidths for the Sharp Regression Discontinuity Estimator","subitem_title_language":"en"}]},"item_type_id":"12","owner":"16","path":["15"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2014-04-01"},"publish_date":"2014-04-01","publish_status":"0","recid":"1139","relation_version_is_last":true,"title":["Simultaneous Selection of Optimal Bandwidths for the Sharp Regression Discontinuity Estimator"],"weko_creator_id":"16","weko_shared_id":-1},"updated":"2023-11-20T08:46:30.800602+00:00"}
