Maurice Obstfeld will be the next IMF chief economist and economic councillor to Christine Lagarde. He will take the job on September 8. From this date Olivier Blanchard, the current chief economist, will be named senior fellow at the Peterson Institute. 

  
Obstfeld is professor at Berkeley University and was currently member of the Council of Economic Advisers at the White House. He is a real specialist in international economics. 

I join his web page at Berkeley. Choose a paper recent or older and you will learn something interesting on the topic.
