So much for that Keynesian stimulus notion (emphasis in the original)
With everyone focused on the 5th anniversary of the Lehman failure, we are taking a quick look at how the world's developed (G7) nations have fared since 2008, and just what the cost to restore "stability" has been. In a nutshell: the G7 have added around $18tn of consolidated debt to a record $140 trillion, relative to only $1tn of nominal GDP activity and nearly $5tn of G7 central bank balance sheet expansion (Fed+BoJ+BoE+ECB). In other words, over the past five years in the developed world, it took $18 dollars of debt (of which 28% was provided by central banks) to generate $1 of growth. For all talk of "deleveraging" G7 consolidated debt has been at a record high 440% for the past four years.
The theory of stimulus -- taking money out of the productive economy, where it is spent based on the information of hundreds of millions of people as to the relative value of millions of potential investments, and handing it to the government to spend based on political calculus -- never made a lick of sense to me. I guess I would have assumed the multiplier in the short term was fractional but at least close to one, indicating in the short run that if we borrow and dump the money into the economy we would get some short-term growth, only to have to pay the piper later. But we are not even seeing this.
