Back on topic, a study to refute a study
And yet the "study" does nothing of the kind. It actually reinforces Keyenes theory.(As it does every time someone looks at this same historical data.)
When federal spending reached its apex employment was, with a very slight lag, at its highest....and after a period of high employment and growth the economy was able to generate jobs as the government laid people off... The very ideal of Keynes prophisied effect.
Its just that your "study" reprises the tired old notion of saying that becasue the govenrment spent a dollar in a war it was different then spending a dollar at any other time. A person "hired" to sail a ship or drive a tank has a job. The same way that they would have a job if they were hired to pave a road or repair a building....
Well, actually, the second investment would leave a legacy, and improve the countries infrastructure and therefore its business environment... ... Freedom I suppose being the very important legacy of the WWII (maybe not WWI so much....)
But the point is your "study" is just a recitation of the fact that it took an inordinate amount of federal money to end the Depression. And that stimulus has to be significant enough to actually prime the economic pump. So your study does nothing but reinforce the notion that the stimulus in Europe was cut off way too soon, and replaced with a damaging austerity program. And that the Stimulus in the US wasn't big enough or long enough to have the effect that the investment required to fight WWII had in reversing the Great Depression.
A bucks a buck Fate....
How or why the government spent it to create employment doesn't matter to an examination of the effect of spending at that level.
Imagine that the nation is an obese man who needs to lose weight. He goes on a strict regimen of dieting to only 1400 calories a day and regular exercise....and loses weight.
His twin obese brother is stranded on a desert island and only manages to consume 1400 calories a day because thats all the food he can catch or find. He also loses weight.
The did the same thing for different reasons with the same effect.
If there werre no WWII, but FDR managed to get support for a massive investment in building infrastructure that hired the same number of people and spent the same amount of money the same effect would have happened.
