U.S. President Richard Nixon adopted Keynesian policies to boost the economy after tightening monetary policy failed in 1970. In 1971 Nixon turned to higher fiscal spending to get the economy closer to full employment. He also adopted wage and price controls. By 1972 the economy had recovered, inflation was at 5.7% and unemployment at 4.9%, and Nixon won re-election. This was the only recovery in an election year since World War II. In international affairs Nixon's policy was to leave the Bretton Woods system and floating the dollar. With a new administration in 1974 inflation surged to 11% and unemployment to 5.6%, because wage and price controls worked only for a short period.
