However, lending interest rates are said to be extremely low and not profitable. This research analyzes this reason by utilizing reinforcement learning algorism. Stock prices can be regarded as a sum of discounted dividends theoretically. The author proposes a dividend amount model including a bank’s risk asset and calculates its derivative coefficient. It tells us that banks are maximizing their profits (dividends) by adjusting their risk asset to their default probabilities (PD). In other words, a bank takes a risk by increasing risk asset when its PD is smaller than the target level (the risk appetite is strong) and reduces risk by decreasing risk asset when its PD is greater than the target level (the risk appetite is weak). The author uses the Merton model, the standard default calculating model, and finds out that local Japanese banks increased their lending amount because of their strong risk appetite. Contributing to the research, the author improves the model using the interest rate term structure and analyzes other countries’ cases.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"8069","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kaneko, Takuya "}]}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34577/00005075","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国際基督教大学","subitem_publisher_language":"ja"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04542134","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"金子, 拓也","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"8062","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":"2022-04-01"}],"displaytype":"detail","filename":"89号論説05金子拓也.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"近年地方銀行の融資残高が増加した背景について—企業金融および強化学習に基づいて合理的な解釈を試みる—","url":"https://icu.repo.nii.ac.jp/record/5296/files/89号論説05金子拓也.pdf"},"version_id":"61aa81fd-5785-43f3-baaf-f237cd0e3c5f"}]},"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":"近年地方銀行の融資残高が増加した背景について—企業金融および強化学習に基づいて合理的な解釈を試みる—","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"近年地方銀行の融資残高が増加した背景について—企業金融および強化学習に基づいて合理的な解釈を試みる—","subitem_title_language":"ja"},{"subitem_title":"Analyzing the Reason Local Japanese Banks are Increasing their Lending Amount These Days","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"14","path":["566"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-04-01"},"publish_date":"2022-04-01","publish_status":"0","recid":"5296","relation_version_is_last":true,"title":["近年地方銀行の融資残高が増加した背景について—企業金融および強化学習に基づいて合理的な解釈を試みる—"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2023-09-30T06:44:30.174291+00:00"}
