Economics, as a branch of the more general theory of human action, deals with all human action, i.e., with mans purposive aiming at the attainment of ends chosen, whatever these ends may be.--Ludwig von Mises
In theory, the two measures should equal one another, in practice they don’t quite, and Mr. Nalewaik argues that GDI is the better of the two.
He finds that when the Commerce Department’s Bureau of Economic Analysis revises its national income and product accounts, GDP figures move more closely inline with GDI. GDI also appears to have a stronger correlation with other economic indicators, and its recent movement around turning points suggests it more closely tracks the economy.
He notes that GDI fell far more sharply in the teeth of the recession, dropping at a 7.3% annual rate in the fourth quarter of 2008, and 7.7% in the first quarter of 2009. GDP, in comparison, fell by 5.4% and 6.4%. Moreover, while GDP showed the economy began to grow in last year’s third quarter, GDI showed it continued to contract. (Fourth-quarter GDI figures aren’t yet available.)

It is the preceding inflation that makes the depression phase necessary. The depression is the process by which the market economy adjusts, throws off the excesses and distortions of the previous inflationary boom, and reestablishes a sound economic condition.
The depression is the unpleasant but necessary reaction to the distortions and excesses of the previous boom. the business cycle is brought about, not by any mysterious failings of the free market economy, but quite the opposite: By systematic intervention by government in the market process. Government intervention brings about bank expansion and inflation, and, when the inflation comes to an end, the subsequent depression-adjustment comes into play.
What the government should do, according to the Misesian analysis of the depression, is absolutely nothing. It should, from the point of view of economic health and ending the depression as quickly as possible, maintain a strict hands off, "laissez-faire" policy. Anything it does will delay and obstruct the adjustment process of the market; the less it does, the more rapidly will the market adjustment process do its work, and sound economic recovery ensue.
