Fischer Sheffey Black (January 11, 1938 – August 30, 1995) was an American economist best known for co-developing the Black–Scholes formula. Throughout his career, he held positions at the University of Chicago, Massachusetts Institute of Technology, and Goldman Sachs. Black died two years prior to the Nobel Memorial Prize in Economic Sciences being awarded to his colleagues Myron Scholes and Robert C. Merton for their work on the Black-Scholes framework and its continuous-time applications. His contributions also extended to the capital asset pricing model, accounting theory, and he made significant, though sometimes contested, advancements in monetary economics and theories concerning business cycles.

Background

Born on January 11, 1938, Black completed his undergraduate studies in physics at Harvard College in 1959 and later received a PhD in applied mathematics from Harvard in 1964. Initially uncertain about his dissertation topic, he shifted interests from physics to mathematics and then to computing and artificial intelligence. During this period, he worked at consultancy firm Bolt, Beranek and Newman developing AI systems and formulated ideas while affiliated with the RAND corporation. Under the mentorship of MIT professor Marvin Minsky, Black ultimately finalized his doctoral research.

Black’s professional journey began at Arthur D. Little, where he gained expertise in economic and financial consulting and formed a partnership with collaborator Jack Treynor. In 1971, he took a position at the University of Chicago before moving to the MIT Sloan School of Management in 1975. He joined Goldman Sachs in 1984 and remained there until his passing.

Economic career

Around 1970, Black turned his attention to monetary policy, engaging with the ongoing debates between Keynesian economists and monetarist theorists. The Keynesian camp, led by Franco Modigliani, viewed credit markets as inherently unstable and supported active monetary and fiscal policy interventions by central banks to maintain steady growth, advocating for discretionary policy measures. Conversely, monetarists under Milton Friedman argued that discretionary central banking introduced volatility and favored a fixed growth rate of money supply aligned with real GDP.

Applying the principles of the capital asset pricing model, Black determined that discretionary monetary policy neither fulfilled Keynesian objectives nor inflicted the damage feared by monetarists. In a 1972 correspondence with Friedman, he highlighted how Federal Reserve actions often prompt private sector responses through Treasury bill adjustments, thereby limiting monetary policy’s influence.

In 1973, Black collaborated with Myron Scholes to publish The Pricing of Options and Corporate Liabilities in The Journal of Political Economy, presenting the now-famous Black–Scholes equation—a foundational achievement in financial economics.

By 1976, Black advanced the idea that uncertainty about future demand and technological progress renders human capital and business cycles inherently unpredictable. Economic expansions occur when technology matches demand conditions; downturns arise from mismatches between these factors. This concept laid groundwork for what would later be recognized as early contributions to real business cycle theory.

Economist Tyler Cowen has remarked that Black’s investigations into monetary economics and business cycle dynamics provide insightful explanations for periods such as the Great Recession, particularly highlighting susceptibility to abrupt economic disturbances.

Black regarded his studies on monetary theory, business cycles, and options pricing as interconnected components within a cohesive theoretical structure. He appreciated the sophistication of equilibrium models and sought to illustrate their relationships. While his work on options theory gained widespread acclaim, he persistently refined his approaches to monetary theory and business cycle analysis, convinced that mathematical methods from option pricing could be effectively applied across these domains.

Business Cycles and Equilibrium (1987)

Fischer Black produced a wide array of scholarly publications, including his distinguished book, Business Cycles and Equilibrium. In this work, he imagines an economy operating without money and maintains that economic and financial markets consistently remain in equilibrium—an idea that retains significance during modern economic downturns. Black disputes conventional monetary theories, especially the quantity theory of money, by arguing that money is an internally generated asset provided by profit-driven banks, opposing the monetarist perspective that treats money as an external variable. His statement that "Monetary and exchange rate policies accomplish almost nothing, and fiscal policies are unimportant in causing or changing business cycles" provoked debate among both Keynesian and Monetarist economists.

Illness and death

After being diagnosed with throat cancer in early 1994, Black initially showed positive recovery following surgery and participated in the International Association of Financial Engineers conference that October, where he was honored with the Financial Engineer of the Year award. Unfortunately, the cancer returned and ultimately led to his passing in August 1995.

Posthumous recognition

Although the Nobel Prize is not awarded after death and Black was not recognized in 1997 when his co-author Scholes received the award for their option pricing model alongside Robert C. Merton, the Nobel committee acknowledged Black’s foundational role in their work.

Black is also credited with co-developing the Black–Derman–Toy model for interest rate derivatives at Goldman Sachs during the 1980s, which was subsequently made publicly available. Furthermore, he co-created the Black–Litterman model for global asset allocation while working at Goldman Sachs.

In 2017, The Journal of Performance Measurement inducted Black into its Performance & Risk Measurement Hall of Fame, celebrating his profound influence on investment performance evaluation and risk management.

Fischer Black Prize

The American Finance Association inaugurated the biennial Fischer Black Prize in 2002 to honor Fischer Black’s legacy. This accolade recognizes a young scholar whose research exemplifies Black’s distinctive approach of producing innovative work with practical relevance to finance.
