The US economy expected to grow 1.5% in 2008 down 0.3% from estimate in October 2007 World Economic Outlook after taking into account a recent update in the model that lowered all forecasts 2005-2008 by half a point. Of this about 0.2 or 0.3% may be the impact of the stimulus package which is included in the estimate. Is this a bit on the high side? Its expectation of growth suggests it does not expect a recession or that it will periodically revise its estimate downward based on new information and the extent of consumption, housing and investment deterioration it sees unfolding in the months ahead. For the European economy it has taken its earlier estimate of 2.1% down to 1.6%. This suggests that it sees the US crisis having an impact in Europe. China's rate of growth will be 10% down 1.4% from 2008 and the Middle East growth about 6% unchanged from 2007, Latin American growth 4.3% down from 5.4% in 2007. This suggests global growth outside USA will remain healthy. However its not clear what would happen if the idea of a recession in the US becomes likely with new information in coming months, and if this is introduced into the model how much would growth in China and the Middle East and India come down in that event. This is the kind of scenario that should also be available from the IMF to know the downside and whether the global growth would sustain till the US recovers from the housing and credit crises in years beyond 2009, given that it would take some time for the excesses there to correct themselves....
