Many static research is based on the distortion due to the monopolistic pricing.Namely, relative prices of goods to leisure become too high and hence the shortage of consumption and excess leisure appear. Thus the equilibrium of monopolistic competition becomes second best. However when the theory is extended to dynamics, there emerges another important effect of monopolistic competition. In the dynamic model, monopolistic power lowers the inflation rate; nominal wage depends on not only current but also future prices. Consequently the relative prices of current goods to future ones become higher by the monopolistic power. It possibly improves the lifetime utility because the unit current labor supply can buy more future goods. Thus the detrimental effect of the reduction of real wages in terms of the current goods is entirely offset by the lowered inflation rate. Accordingly, there only remains the increase of the monopoly rent due to the product differentiation. In other words, Nash equilibrium (price-making equilibrium) can dominate Walrasian equilibrium (price-taking equilibrium) in the dynamic model.","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"論説","subitem_description_type":"Other"},{"subitem_description":"General Article","subitem_description_type":"Other"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"27257","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Otaki, Masayuki"}]},{"nameIdentifiers":[{"nameIdentifier":"27258","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Tamai, Yoshihiro"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学社会科学研究所"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00108966","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03873307","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"300","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Institute of Social Science, The University of Tokyo"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学社会科学研究所"},{"subitem_text_value":"神奈川大学経済学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大瀧, 雅之"}],"nameIdentifiers":[{"nameIdentifier":"27255","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"玉井, 義浩"}],"nameIdentifiers":[{"nameIdentifier":"27256","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":"2017-06-08"}],"displaytype":"detail","filename":"shk061001007.pdf","filesize":[{"value":"490.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"shk061001007.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/17063/files/shk061001007.pdf"},"version_id":"f4ab3df7-461f-468f-86d5-c5ecef9283c6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"貨幣を保蔵手段としたOLGモデル","subitem_subject_scheme":"Other"},{"subitem_subject":"動学的独占的競争","subitem_subject_scheme":"Other"},{"subitem_subject":"独占レント","subitem_subject_scheme":"Other"},{"subitem_subject":"インフレーション","subitem_subject_scheme":"Other"},{"subitem_subject":"貨幣経済に固有の死重","subitem_subject_scheme":"Other"}]},"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":"貨幣経済における独占的競争の動学的役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"貨幣経済における独占的競争の動学的役割"}]},"item_type_id":"4","owner":"1","path":["920","921"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-01"},"publish_date":"2011-06-01","publish_status":"0","recid":"17063","relation_version_is_last":true,"title":["貨幣経済における独占的競争の動学的役割"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:55:56.042440+00:00"}
