Fisher was born in New York City and received both his undergraduate degree and his PhD from Harvard University. He joined the MIT faculty in 1960, after a one-year post-PhD stint as an assistant professor at the University of Chicago. Fisher spent the rest of his career at MIT. In 2000, he was appointed the inaugural holder of the Jane Berkowitz Carlton and Dennis William Carlton Professorship of Microeconomics. He became a professor emeritus in 2004.
Fisher was a versatile economist who made important contributions to economic theory, econometric methods, and the empirical analysis of firm and industry behavior. He was best known for his research on aggregation theory, estimation of simultaneous equation models, and the measurement and consequences of industry concentration. His contributions were widely celebrated. In 1973, he received the John Bates Clark Medal from the American Economic Association, an award then presented every other year to the American economist under the age of 40 who is judged to have made the most significant contributions to economic thought and knowledge. He served as president of the Econometric Society, was a fellow of the American Academy of Arts and Sciences, and held an honorary degree from the Hebrew University in Jerusalem.
Fisher was actively involved in antitrust policy. He served as the lead economic expert for IBM in the 1970s, when the U.S. Department of Justice sued the firm for anticompetitive behavior. After the case was settled in the early 1980s, he and co-authors John McGowan and Joen Greenwood published “Folded, Spindled and Mutilated,” a comprehensive analysis of the economic issues in the case. Several years later, Fisher served as the lead expert for the Department of Justice in another high-profile antitrust case, U.S. v. Microsoft.
