It utilizes a large text data of real time, relatively high-frequency market news and takes account of the difficulties in incorporating market sentiment into the models. To the best of our knowledge, this is the first attempt to use this category of data in term-structure models.\n Although market sentiment or market confidence is often regarded as an important driver of asset markets, it is not explicitly incorporated in traditional empirical factor models for daily yield curve data because they are unobservable. To overcome this problem, we use a text mining approach to generate observable variables which are driven by otherwise unobservable sentiment factors. Then, applying the Monte Carlo filter as a filtering method in a state space Bayesian filtering approach, we estimate the dynamic stochastic structure of these latent factors from observable variables driven by these latent variables.\n As a result, the three-factor model with text mining is able to distinguish (1) a spread-steepening factor which is driven by pessimists' view and explaining the spreads related to ultra-long term yields from (2) a spread-flattening factor which is driven by optimists' view and in uencing the long and medium term spreads. Also, the three-factor model with text mining has better fitting to the observed yields than the model without text mining.\n Moreover, we collect market participants' views about specific spreads in the term structure and find that the movement of the identified sentiment factors are consistent with the market participants' views, and thus market sentiment.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Publisher's another name: JSPS Grants-in-Aid for Scientific Research (S) Central Bank Communication Design","subitem_description_type":"Other"}]},"item_8_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Research Project on Central Bank Communication"}]},"item_8_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.centralbank.e.u-tokyo.ac.jp/en/category/research-data/","subitem_relation_type_select":"URI"}}]},"item_8_select_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_8_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"National Graduate Institute for Policy Studies (GRIPS) and CARF, University of Tokyo"},{"subitem_text_value":"Graduate School of Economics and CARF, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Nishimura, Kiyohiko G."}],"nameIdentifiers":[{"nameIdentifier":"152585","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sato, Seisho"}],"nameIdentifiers":[{"nameIdentifier":"152586","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Akihiko"}],"nameIdentifiers":[{"nameIdentifier":"152587","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":"2018-11-06"}],"displaytype":"detail","filename":"cb-wp003.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"cb-wp003.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/51225/files/cb-wp003.pdf"},"version_id":"8b6dd833-0777-4a16-a9c7-44be5f9c213e"}]},"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","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"Term Structure Models During the Global Financial Crisis : A Parsimonious Text Mining Approach","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Term Structure Models During the Global Financial Crisis : A Parsimonious Text Mining Approach"}]},"item_type_id":"8","owner":"1","path":["7892","7439"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-06"},"publish_date":"2018-11-06","publish_status":"0","recid":"51225","relation_version_is_last":true,"title":["Term Structure Models During the Global Financial Crisis : A Parsimonious Text Mining Approach"],"weko_creator_id":"1","weko_shared_id":2},"updated":"2022-12-19T04:27:17.326087+00:00"}
