This graph isn’t very exciting but it shows how US GDP has grown to 12.75 trillion dollars (using quarterly data up to 2005 Q4, seasonally adjusted at annual rates, downloaded from
www.bea.gov ).
I think I do have the revised figures, Ivan, but this shows the general picture. The top line is total production/spending. The other four lines are the main components that add to the total.
A few highlights: Government spending (light blue) and private investment (brown) are almost the same percentage of GDP today as in 1990, approx. 18% each. Personal consumption has grown by roughly 5% to 70% of GDP and the trade deficit has grown by roughly -5% to -6% of GDP, both since 1990.
If you consider the 1990/1991 recession and the 2001 slowdown, it was private investment spending that actually fell in both cases. Consumer spending didn’t fall.
So, short of a depression, the whole argument about whether to expect a recession, expressed as negative GDP growth, seems to depend on the behaviour of the two relatively small items that can have negative growth – private investment and the trade deficit.
(OK, slower consumer and government growth contribute in the total, but only investment growth and trade can be negative numbers).
Look at the trade deficit. Suppose the current trend continued and the deficit increased to 9% of GDP without provoking a crisis. The extra negative 3% would probably send the total growth below zero – a recession. But so what? If there isn’t a crisis – as in the current situation – whose worse off? Employment may actually increase.
The point I’m making is to question GDP growth as a means of keeping score. Surely wealth, health and employment are better measures of “growth” in an economy.
Now consider private investment. It’s made up of one-third “residential” fixed investment (housing) and two-thirds non-residential, i.e. business spending.
These two behaved completely differently in the two ‘recessions’. In 1990 residential spending dropped by 20% but business spending hardly dropped at all. In 2001 business spending dropped by 10% but residential spending didn’t drop.
Now wouldn’t you think that a drop in business investment is worse than a drop in house building? But 2001 is considered a mild (or non-existent) recession compared to 1990/91.
So fine, let’s measure GDP growth, but shouldn’t we pay more attention to employment, net wealth and wealth distribution?
