In both the conditional and stochastic volatility literature, there has been some confusion between the definitions of asymmetry and leverage. In this paper, we first show the relationship among conditional, stochastic, integrated and realized volatilities. Then we develop a new asymmetric volatility model, which takes account of small and large, and positive and negative, shocks. Using the new specification, we examine alternative volatility models that have recently been developed and estimated in order to understand the differences and similarities in the definitions of asymmetry and leverage. We extend the new specification to realized volatility by taking account of measurement errors. As an empirical example, we apply the new model to the realized volatility of Standard and Poor’s 500 Composite Index using Efficient Importance Sampling to show that the new specification of asymmetry significantly improves the goodness of fit, and that the out-of-sample forecasts and VaR thresholds are satisfactory","subitem_description_type":"Abstract"}]},"item_8_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"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/2009/2009cf656ab.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":"Faculty of Economics Soka University, Japan"},{"subitem_text_value":"Econometric Institute Erasmus School of Economics Erasmus University Rotterdam"},{"subitem_text_value":"Tinbergen Institute The Netherlands"},{"subitem_text_value":"Center for International Research on the Japanese Economy (CIRJE) Faculty of Economics University of Tokyo"},{"subitem_text_value":"Department of Economics Pontifical Catholic University of Rio de Janeiro"}]},"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":"Asai, Manabu"}],"nameIdentifiers":[{"nameIdentifier":"96889","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"McAleer, Michael"}],"nameIdentifiers":[{"nameIdentifier":"96890","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Medeiros, Marcelo C."}],"nameIdentifiers":[{"nameIdentifier":"96891","nameIdentifierScheme":"WEKO"}]}]},"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":"Asymmetry and Leverage in Realized Volatility","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Asymmetry and Leverage in Realized Volatility"}]},"item_type_id":"8","owner":"1","path":["7436","7434"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-05-31"},"publish_date":"2013-05-31","publish_status":"0","recid":"42100","relation_version_is_last":true,"title":["Asymmetry and Leverage in Realized Volatility"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:14:04.953983+00:00"}
