An American economist known for his development of mathematical models for pricing investments. In particular, he helped create the Black-Scholes model, which is used to determine the appropriate price for option contracts. In the 1970s, he argued against both Keynesians, who believed central banks ought to have discretion to raise or lower the money supply, and monetarists, who thought the money supply should grow at a constant rate. Black lived from 1938 to 1995.
