PARIS – Like brothers in arms united in combat but divided in peace, Europe and the United States, which had fought depression jointly in 2009, started voicing disagreements in 2010 and begin 2011 with divergent positions on macroeconomic policy. The price of divergence could be steep: though the worst is over, effective coordination of policy is still needed at a time when rebalancing the global economy, as the G-20 has called for, is far from being accomplished.
The transatlantic divide is evident with respect to monetary policy. In November of last year, the US Federal Reserve’s decision to launch a new cycle of “quantitative easing” (buying up government bonds through monetary creation) triggered fierce criticism in Europe. While the European Central Bank has also been buying government bonds since last spring, the amount is relatively small (€70 billion, compared to the Fed’s $600 billion program), and is meant only to support troubled eurozone members, with particular care taken to avoid any impact on money supply.
