Robert Fry Engle, 3d, 1942–, American economist, b. Syracuse, N.Y., Ph.D. Cornell, 1969. He has been on the faculty of the Massachusetts Intitute of Technology (1969–75), Univ. of California, San Diego (1975–99), and New York Univ. (1999–). With Clive Granger, Engle improved the way economists study sets of data over time, and enabled them to study the relationship between different sets of such data. Engle in particular developed a model that allows investors to forecast the future volatility of investments and determine the risk involved. Engle and Granger shared the Nobel Memorial Prize in Economic Sciences in 2003 for their work.
