Professor Gauti Eggertsson’s work featured as one of five economists that established the “Princeton school of monetary economics” in the early 2000s, which had a major impact on how the Federal Reserve responded to the financial crisis in 2008.
Eggertsson's work is featured along with the work of former Fed Chairman Ben Bernanke, Nobel Laurate of Economics Paul Krugman, Lars E.O. Svensson former deputy governor of Sweden’s central bank, and Michael Woodford, who is by many considered the leading monetary theorist today. While Professor Eggertsson was a student at Princeton at the time, the other four were faculty members. According to the article, the work done by the five economists provided the conceptual framework that guided monetary policy action in response to the 2008 crisis, and ever since, for example, it has shaped the view of th fiscal policy response during the COVID pandemic.
