Oldřich Alfons Vašíček (born 1942) is a Czech mathematician and quantitative analyst. He received his master's degree in math from the Czech Technical University, 1964, and a doctorate in probability theory from Charles University four years later. Vašíček left for America, settled in San Francisco, and found employment in the management science department of Wells Fargo Bank in January 1969. In 1970, that bank sponsored a conference that included Fischer Black and Myron Scholes, who had just begun thinking seriously about the problem of valuing stock options. Of course, their paper on that subject, timed so as to coincide with a related paper by Robert C. Merton, would revolutionize financial economics three years later. Even their preliminary thoughts at the 1970 conference excited Vašíček, who soon made related issues his own life's work. Vašíček's own breakthrough paper, describing the dynamics of the yield curve, appeared in the Journal of Financial Economics in 1977. In recognition of that paper, and subsequent work, the International Association of Financial Engineers named Vašíček its IAFE/Sungard Financial Engineer of the Year, in 2004. The mean-reverting short rate model he describes is commonly known as the Vasicek model. In 1989 Stephen Kealhofer, John McQuown and Oldřich Vašíček founded company KMV. In 2002 the three entrepreneurs sold the company to Moody's.〔Moody's, ''(Moody's Corporation to Acquire KMV )'' (press release), 11 February 2002〕 In 2007, Moody's KMV was renamed to Moody's Analytics.〔http://www.allbusiness.com/services/business-services/4540649-1.html Moody’s Corporation Announces New Business Unit Structure August 7, 2007〕 Vašíček has received the Risk magazine Lifetime Achievement Award. He has been inducted into the Derivatives Strategy Hall of Fame, the Fixed Income Analysts Society Hall of Fame and the Risk Magazine Hall of Fame. Peter Carr, Head of Quantitative Financial Research at Bloomberg LP, included Vašíček's paper ''Probability of Loss on Loan Portfolio'' in book ''Derivatives Pricing: The Classic Collection'', which was marketed as a selection of 19 most influential papers on quantitative finance.〔pdf version of the paper is freely available on moodysanalytics.com website (http://www.moodysanalytics.com/~/media/Insight/Quantitative-Research/Portfolio-Modeling/87-12-02-Probability-of-Loss-on-Loan-Portfolio.ashx)〕 He plays the flute and is an avid windsurfer. He has three sons, one of whom is the screenwriter John Vasicek. == Notes == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oldřich Vašíček」の詳細全文を読む スポンサード リンク
