Whereas there is now a growing\nliterature in risk, uncertainty and the market, the operational theory of risk-averse\noligopoly has been rather underdeveloped so far ．One of the reasons for such\nunderdevelopment is that the established concept of risk aversion remains too abstract\nrather than reasonably operational, whence very few economists have dared to study\nthe economic consequences of a change of risk aversion by firms.\nIn this paper, we attempt to combine the constant-absolute-risk aversion function\ndeveloped by K. J. Arrow and J. W. Pratt, two great economists of the 20th century, and\nthe normal distribution function invented by K.F. Gauss, a mathematical genius of the\n19th century: The resulting situation may be called the KARA-NORMAL case. We\nintend to invent a very useful mathematical theorem for this specific yet important case,\nand then apply it to the theory of risk-averse oligopoly. In particular, the impact of\nincreasing risk aversion on the outputs of duopolies are carefully examined. It is\nshown among other things that the comparative static results depend on the degree of\nrisk aversion and the state of product differentiation.","subitem_description_type":"Abstract"}]},"item_7_description_7":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"CRR Discussion Paper, Series A, No. A-13, pp. 1-22","subitem_description_type":"Other"}]},"item_7_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"サカイ, ヤスヒロ"}]}]},"item_7_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"酒井, 泰弘"}]}]},"item_7_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Center for Risk Research (CRR), Shiga University"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sakai, Yasuhiro"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-09-14"}],"displaytype":"detail","filename":"DPA13_p.1-22 酒井泰弘.pdf","filesize":[{"value":"982.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"DPA13_p.1-22 酒井泰弘.pdf","url":"https://shiga-u.repo.nii.ac.jp/record/9837/files/DPA13_p.1-22 酒井泰弘.pdf"},"version_id":"081af5bb-7600-4fc5-ae08-9873eca90771"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Risk aversion","subitem_subject_scheme":"Other"},{"subitem_subject":"expected utility","subitem_subject_scheme":"Other"},{"subitem_subject":"oligopoly","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":"Risk Aversion and Expected Utility : The Constant-Absolute-Risk Aversion Function and its Application to Oligopoly","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Risk Aversion and Expected Utility : The Constant-Absolute-Risk Aversion Function and its Application to Oligopoly"}]},"item_type_id":"7","owner":"1","path":["1163"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-11-10"},"publish_date":"2014-11-10","publish_status":"0","recid":"9837","relation_version_is_last":true,"title":["Risk Aversion and Expected Utility : The Constant-Absolute-Risk Aversion Function and its Application to Oligopoly"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:22:49.521275+00:00"}
