The dollar's fall on foreign exchange markets is not enough to cut the U.S. current account deficit, the IMF's chief economist said in an interview published in Les Echos business newspaper on Tuesday. Raghuram Rajan said Americans should save more and spend less, but the United States' main trading partners should also catch up with U.S. growth rates. Asian states should consider more flexibility in their foreign exchange rates, Rajan told the French-language daily. "The fall of the dollar alone will not cut the American current account deficit," Rajan said. "Part of the problem comes from the gap between the growth rates of the United States and its main trading partners. "Japan and Europe must increase their growth potential by structural reforms. And Asian countries should consider more flexibility in their exchange rates. They could that way import more."////
