Thomas J. Sargent

In 2016, Sargent helped found the non-profit QuantEcon project, which is dedicated to the development and documentation of modern open source computational tools for economics, econometrics, and decision making.

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.

On October 10, 2011, Sargent, with Christopher A. Sims, was awarded the Nobel Memorial Prize in Economic Sciences. The award cited their "empirical research on cause and effect in the macroeconomy". His Nobel lecture, "United States Then, Europe Now," was delivered on December 11, 2011.

Sargent is notable for making short speeches. For example, in 2007 his Berkeley graduation speech consumed 335 words.

In 1975 he and Wallace proposed the policy-ineffectiveness proposition, which challenged a basic assumption of Keynesian economics.

Sargent graduated from Monrovia High School. He earned his B.A. from the University of California, Berkeley in 1964, being the University Medalist as Most Distinguished Scholar in Class of 1964, and his PhD from Harvard in 1968, under supervision of John R. Meyer. Sargent's classmates at Harvard included Christopher A. Sims. After serving in the U.S. Army as a first lieutenant and captain, he moved on to teaching. He held teaching positions at the University of Pennsylvania (1970–71), University of Minnesota (1971–87), University of Chicago (1991–98), Stanford University (1998–2002) and Princeton University (2009), and is currently a professor of economics at New York University (since 2002). He previously held the position of President of the American Economic Association and the Econometric Society where he has been a fellow since 1976. In 1983, Sargent was elected to the National Academy of Sciences and also the American Academy of Arts and Sciences. He has been a senior fellow of the Hoover Institution at Stanford University since 1987.

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 "Two Questions about European Unemployment," the answer is that "Europe has stronger employment protection despite also having had more generous government supplied unemployment compensation"." While the institutional differences remained the same over this time period, the microeconomic environment for workers changed, with a higher risk of human capital depreciation in the 1980s.

Thomas John Sargent (born July 19, 1943) is an American economist and 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 2020, he ranks as the 29th most cited economist 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".
