A Nobel prizewinning economist, known for his models that analyze what causes fluctuations in the national economy, will speak at the Jon M. Huntsman School of Business Friday, Oct. 8. Ed Prescott, who won the 2004 Nobel Prize in Economics, will speak at 12:30 p.m. in the Orson A. Christensen Auditorium (room 215 in the George S.Eccles Business building). The event, part of the George S. Eccles Distinguished Lecture Series, is free and open to the public. Dean Douglas Anderson of the Huntsman School of Business says Prescott’s models are considered by many to be the foundation of macroeconomic theory.
