Missing Growth Multipliers
In its April 2010 World Economic Outlook, the IMF predicted that global GDP growth would exceed 4% in 2010, with a steady annual growth rate of 4.5% maintained through 2015. But the forecast seriously underestimated the tax and world-trade multipliers, resulting in much lower growth than expected.

But the forecast proved to be far too optimistic.
