Sargent is the author of influential books and articles on the coordination of monetary and fiscal policy, inflation, and unemployment. His work with Nobelist Robert Lucas on rational expectations and macroeconomics was field-defining. His current projects include an examination of persistent unemployment in Europe and a study of the changing behavior of the Federal Reserve since World War II and the responsiveness of the US economy to Fed actions.
