Recent data releases suggest that the current economic experience on the two sides of the Atlantic is very different. The latest data shows that the UK economy is now contracting and unemployment is rising as fiscal austerity begins to bite. Conversely, the latest US data shows that growth is on-going and the unemployment rate is finally starting to fall. This may be a temporary return to growth because the political developments that may occur later in this year could see some serious, British-style fiscal austerity being imposed on the US economy. At present though, my assessment of these disparate trends is that fiscal austerity is contractionary if non-government spending is insufficient to offset the decline in public spending. However, some observers are trying to hold out the US experience as vindicating those who believe in the notion of a “fiscal contraction expansion”. But the data tells us clearly that the US is not an example of this mania.
