For example, Google has its search engine, and users are potential customers for their advertisement services. In two-sided markets the platform providers have a pair of markets that are linked by inter-market externality. If the members of one of the two-sided markets are better off by the increase of the size of the other market, the second market has positive indirect network effect on the first. This inter-market externality enables the profit subsidy from the first to the second. This asymmetric character of the two-sided market is called“the Seesaw Principle”that has been studied in the scholarly literature by comparative statistics of two-sided markets. In the scholarly literature, it is well known that platformers maximize the sum of each market and that it causes the inefficiency of the price mechanism for each market. However, since most of the studies fix the number of platforms exogenously, the impact of the network effect on the market size is unclear. In this paper, the problem is formulated as a Bertrand–Nash oligopolistic competition. In contrast to what has been suggested by the existing scholarly literature, we have demonstrated that in our setting, the indirect network effect can result in monopoly nor competitiveness. Also, we have shown analytically how network effects widen the gap among platforms.","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東洋英和女学院大学大学院"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12040336","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13497715","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"長谷川, かおり"},{"creatorName":"ハセガワ, カオリ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"534","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000006216610","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000006216610"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2022-03-22"}],"displaytype":"detail","filename":"TEDK-N18_P1-10.pdf","filesize":[{"value":"911.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TEDK-N18_P1-10","url":"https://toyoeiwa.repo.nii.ac.jp/record/1657/files/TEDK-N18_P1-10.pdf"},"version_id":"8b6129f2-994b-4580-a2a3-33be309c3d20"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"両面性市場","subitem_subject_scheme":"Other"},{"subitem_subject":"間接ネットワーク効果","subitem_subject_scheme":"Other"},{"subitem_subject":"プラットフォーム","subitem_subject_scheme":"Other"},{"subitem_subject":"直接ネットワーク効果","subitem_subject_scheme":"Other"},{"subitem_subject":"ベルトラン競争","subitem_subject_scheme":"Other"},{"subitem_subject":"Two-sided market","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Indirect Network Effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Direct Network Effect","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Platform","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Bertrand Competition","subitem_subject_language":"en","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":"両面性市場におけるベルトラン競争：ネットワーク効果はいつプラットフォーム間格差を広げるか","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"両面性市場におけるベルトラン競争：ネットワーク効果はいつプラットフォーム間格差を広げるか"},{"subitem_title":"Two-sided Market and Bertrand Competition: When Do Indirect Network Effects Widen the Platformers’Gap?","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"17","path":["316"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-03-22"},"publish_date":"2022-03-22","publish_status":"0","recid":"1657","relation_version_is_last":true,"title":["両面性市場におけるベルトラン競争：ネットワーク効果はいつプラットフォーム間格差を広げるか"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-19T10:39:32.121443+00:00"}
