Mathematically, this methodology is justified by Watanabe theory([27]) in Malliavin calculus.// In practical applications, it is desirable to investigate the accuracy and stability of the method especially with expansion up to high orders in situations where the underlying processes are highly volatile as seen in the recent financial markets.// Although Takahashi[17], [18] and Takahashi and Takehara [20] provided explicit formulas for the expansion up to the third order, to our best knowledge a general computation scheme for an arbitraryorder expansion has not been given yet.// This paper proposes two general methods for computing the conditional expectations that are powerful especially for high order expansions: The first one, as an extension of the method introduced by the preceding papers, presents a unified scheme for computation of the conditional expectations. The second one develops a new calculation algorithm for computing the coefficients of the expansion through solving a system of ordinary differential equations that is equivalent to computing the conditional expectations. To demonstrate their effectiveness, the paper gives numerical examples of the approximation for - SABR model up to the fifth order and a cross-currency Libor market model with a general stochastic volatility model of the spot foreign exchange rate up to the fourth order.","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Subsequenlty published in The Proceedings of KIER-TMU International Workshop on Financial Engineering, pp. 231-251, 2010, World Scientifc, June, 2011.","subitem_description_type":"Other"},{"subitem_description":"本文フィルはリンク先を参照のこと","subitem_description_type":"Other"}]},"item_8_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本経済国際共同センター"}]},"item_8_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.cirje.e.u-tokyo.ac.jp/research/dp/2010/2010cf728ab.html","subitem_relation_type_select":"URI"}}]},"item_8_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11450569","subitem_source_identifier_type":"NCID"}]},"item_8_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"335","subitem_subject_scheme":"NDC"}]},"item_8_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"Center for International Research on the Japanese Economy"}]},"item_8_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Graduate School of Economics, the University of Tokyo"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Takehara, Kohta"}],"nameIdentifiers":[{"nameIdentifier":"98567","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahashi, Akihiko"}],"nameIdentifiers":[{"nameIdentifier":"98568","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Toda, Masashi"}],"nameIdentifiers":[{"nameIdentifier":"98569","nameIdentifierScheme":"WEKO"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Asymptotic Expansion","subitem_subject_scheme":"Other"},{"subitem_subject":"Malliavin Calculus","subitem_subject_scheme":"Other"},{"subitem_subject":"Approximation Formula","subitem_subject_scheme":"Other"},{"subitem_subject":"Stochastic Volatility","subitem_subject_scheme":"Other"},{"subitem_subject":"λ-SABR Model","subitem_subject_scheme":"Other"},{"subitem_subject":"Libor Market Model","subitem_subject_scheme":"Other"},{"subitem_subject":"Currency Options","subitem_subject_scheme":"Other"},{"subitem_subject":"AMS Subject Classifications: 91G80, 91G20, 60H07, 60H30, 60H35","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","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"New Unified Computational Algorithm in a High-Order Asymptotic Expansion Scheme","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"New Unified Computational Algorithm in a High-Order Asymptotic Expansion Scheme"}]},"item_type_id":"8","owner":"1","path":["7436","7434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-01-17"},"publish_date":"2017-01-17","publish_status":"0","recid":"42870","relation_version_is_last":true,"title":["New Unified Computational Algorithm in a High-Order Asymptotic Expansion Scheme"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:18:00.989655+00:00"}
