Thomas John ""Tom"" Sargent (born July 19, 1943) is an American economist, who is currently the W.R. Berkley Professor of Economics and Business at New York University. He specializes in the fields of macroeconomics, monetary economics and time series econometrics. As of 2014, he ranks fourteenth among the most cited economists in the world. He was awarded the Nobel Memorial Prize in Economics in 2011 together with Christopher A. Sims ""for their empirical research on cause and effect in the macroeconomy"".
Sargent is one of the leaders of the ""rational expectations revolution,"" which argues that the people being modeled by economists can predict the future, or the probability of future outcomes, at least as well as the economist can with his model. Rational expectations was introduced into economics by John Muth, then Robert Lucas, Jr., and Edward C. Prescott took it much farther. By some works written in close collaboration with Lucas and Neil Wallace, Thomas J. Sargent could fundamentally contribute to the evolution of new classical macroeconomics.
Sargent has pursued a research program with Ljungqvist designed to understand determinants of differences in unemployment outcomes in Europe and the United States during the last 30 years. The two key questions the program addresses are why, in the 1950s and 1960s, unemployment was systematically lower in Europe than in the United States and why, for two and a half decades after 1980, unemployment has been systematically higher in Europe than in the United States.
In 2011, he was awarded the NAS Award for Scientific Reviewing from the National Academy of Sciences and, in September, he became the recipient of the 2011 CME Group-MSRI Prize in Innovative Quantitative Applications. Sargent is known as a devoted teacher. Among his PhD advisees are men and women at the forefront of macroeconomic research Sargent's reading group at Stanford and NYU is a famous institution among graduate students in economics
