One of President Obama's economic advisers will leave the administration to become the chief economist of the International Monetary Fund in September, the organization announced Monday.

Maurice Obstfeld, a member of the Council of Economic Advisers, will leave the administration after just over a year. Obstfeld is a well-known expert on international economics, having written textbooks on the topic and previously taught at the University of California, Berkeley.

IMF Managing Director Christine Lagarde said she was "thrilled" to have Obstfeld join the IMF, calling him "one of the most influential macroeconomists in the world."

The three-member Council of Economic Advisers, headed by Jason Furman, is tasked with providing the president analysis on all matters relating to the economy.

In his time on the council, Obstfeld has played less of a public role than Furman and Betsey Stevenson, the third member, both of whom have done press events and maintain Twitter accounts with which they respond to news events or discuss White House policies.

One of Obstfeld's textbooks, Foundations of International Macroeconomics, was written with Harvard professor Kenneth Rogoff, who previously held the role Obstfeld will assume in September and whose studies finding that high government debt slows economic growth have attracted wide notice on Capitol Hill. His other textbook, International Economics, was co-authored by Paul Krugman, the Nobel Prize-winning economist and high-profile liberal New York Times columnist.
