In 2010 Chicago Federal Reserve president Charles Evans sugggested the Fed adopt a "7-3 rule"- the Fed would keep interest rates low and credit flowing till unemployment dropped below 7%, and inflation was below 2.5% and not taking off. He modified this to keeping rates low till unemployment reaches 6.5%, as long as inflation remained below 2.5%, on Nov. 27, 2012. In Fed meetings Evans was supported by vice chairman Janet Yellen, with Minneapolis Fed president Kocherlakota and Boston Fed president Rosengren offering similiar proposals. On Dec. 12, 2012, Fed chairman Bernanke announced a position very close to what Evans has suggested. Charles Evans, worked on the staff of the Chicago Fed for 20 years before being appointed president of the Chicago Fed in 2007, at the beginning of the financial crisis.
