Robert F. Engle

Verified Timeline

Lore & Background

Robert F. Engle was born in Syracuse, New York into a Quaker family. He graduated from Williams College with a B.S. in physics, then earned an M.S. in physics and a Ph.D. in economics from Cornell University in 1966 and 1969 respectively. After completing his PhD, he became an economics professor at the Massachusetts Institute of Technology from 1969 to 1977. He joined the faculty of the University of California, San Diego (UCSD) in 1975, retiring from UCSD in 2003. He now holds positions of professor emeritus and research professor at UCSD. He currently teaches at New York University, Stern School of Business where he is the Michael Armellino professor in Management of Financial Services. At New York University, Engle teaches for the Master of Science in Risk Management Program for Executives. Engle's most important contribution was his path-breaking discovery of a method for analyzing unpredictable movements in financial market prices and interest rates. Accurate characterization and prediction of these volatile movements are essential for quantifying and effectively managing risk. For example, risk measurement plays a key role in pricing options and financial derivatives. Previous researchers had either assumed constant volatility or had used simple devices to approximate it. Engle developed new statistical models of volatility that captured the tendency of stock prices and other financial variables to move between high volatility and low volatility periods ("Autoregressive Conditional Heteroskedasticity: ARCH"). These statistical models have become essential tools of modern arbitrage pricing theory and practice. In August 1969, Engle married Marianne Eger. They have two children, a daughter and a son. His wife's mother is Edith Eger, a clinical psychologist, author, and survivor of the Holocaust. Engle was the central founder and director of NYU-Stern's Volatility Institute which publishes weekly data on systemic risk across countries on its V-LAB site. He was awarded a Doctor Honoris Causa by the Comillas Pontifical University in Spain in 2024.

Reader's Guide

Robert F. Engle's significance lies in his development of ARCH models, which revolutionized the analysis of economic and financial time series by allowing for time-varying volatility. Before his work, researchers typically assumed constant volatility or used simple devices to approximate it, which limited the accuracy of risk measurement and pricing of financial derivatives. Engle's models provided a rigorous statistical framework to capture the observed clustering of volatility—periods of high turbulence followed by calm—enabling more precise quantification and management of financial risk. This breakthrough earned him the 2003 Nobel Memorial Prize in Economic Sciences, shared with Clive Granger, and his methods are now standard in both academic research and industry practice, particularly in options pricing, portfolio risk management, and systemic risk monitoring. His ongoing work through the Volatility Institute at NYU Stern continues to apply these concepts to real-time measurement of financial stability across countries.
