Scholes, Myron S.

▪ Canadian-American economist

in full  Myron Samuel Scholes 

born January 7, 1941, Timmins, Ontario, Canada

      Canadian-born American economist best known for his work with colleague Fischer Black on the Black-Scholes option valuation formula, which made options (stock option) trading more accessible by giving investors a benchmark for valuing. Scholes shared the 1997 Nobel Prize for Economics with Robert C. Merton (Merton, Robert C.), who generalized the Black-Scholes formula to make it apply to other areas of finance. (Black, who died in 1995, was ineligible for the Nobel Prize, which is not awarded posthumously.)

      After attending McMaster University in Hamilton, Ontario (B.A., 1961), Scholes studied under Nobel laureate Merton H. Miller at the University of Chicago (M.B.A., 1964; Ph.D., 1970). Scholes taught at the Massachusetts Institute of Technology (1968–73) and the University of Chicago (1973–83) before joining Stanford University in 1983 as a professor of both law and finance, becoming emeritus in 1996. He also worked with many economic and financial institutions, including the National Bureau of Economic Research, Salomon Brothers, and Long-Term Capital Management (LTCM), which Merton cofounded in 1994. Because of its highly leveraged positions, LTCM lost more than $4 billion in 1998.

      Before the Black-Scholes formula appeared in 1973, investors lacked realistic means for determining the future value of an option. Though it was complex and involved many assumptions and restrictions, the formula showed that shares and call options could be combined to form a riskless portfolio. This approach was adapted by traders worldwide as the main method for valuing stock options. Merton expanded the formula to other areas of finance, such as home mortgages, and to risk management in general.
