I'm sure economists have a much stricter definition of 'why' than
the rest of us.  Do you mean that efforts to predict business cycles
are hopeless, or is there controversy over a basic viewpoint like 
business cycles are caused by the improper weighting of temporal
business patterns in the human brain?  From psychology, there seems to
be a very good fundamental explanation for business cycles, eg a bank
officer whose last 3 yrs of loans have performed flawlessly and whose
coffers are flush with money *will* lower his lending standards, since
his recent experience tells him it is safe to do so. Understandably, we
are a hell of a long way from being able to predict the
next business cycle from such an approach.

Yes, I think that it's true.  Was there any general theory of business
cycles before Keynes? But I believe that size has been a larger factor than
knowledge.  Doing economics by almanac, I'll contribute government
purchases as % of GNP.

	  Federal  Total
1929     1.3%     8.5%
1938     6.5     15.5
1955    11.1     18.8
1965     9.7     20.1

Prior to WWI, a lot of our economy was probably
off the books, so any numbers you have for those times may overemphasize
the government fraction.  Government spending is not immune to 
to recession, but Federal spending doesn't track it very closely.
Most states cannot run deficits, so must respond within a year.  Since
the 30's the Federal budget has grown tremendously and is a
stabilizing influence.  When the entire Federal budget was less than 1%
of GNP, mammoth deficit spending would have been nearly unnoticeable.
The obvious task is to compare spending levels and recession depths
in Europe.  Any data?
