You know, I hate to spoil things, but I must say, I think Milton
Friedman has a better plate. This is from an article I came across:
"Years ago, trying to find the Friedman’s apartment in San
Francisco, I knew I was in the right location when I spotted a car
with the number plate MV = PT."

The phenomenon of bust and depression was observed and
argued about long before the Great Depression and long before
Keynes wrote his General Theory.
A fully satisfying explanation requires that we consider the
phenomenon of boom, bust, depression, and recovery.
But sorting out the differences between Milton Friedman and
Maynard Keynes can be achieved with the narrower focus, i.e.,
bust and depression.
This focus suggests two questions in need of an answer:
1. What caused the bust? What was the triggering
mechanism? What change in market conditions required
adjustments of some kind on an economywide scale?
Keynes claimed it was a waning of animal spirits.
Friedman pointed to the collapse in the money supply.
2. Why did it take so long for markets to adjust to the
changed market conditions? If prices, wages, and interest
rates needed to adjust, why didn’t they adjust?
Keynes claimed it was price and wage-rate stickiness.
Friedman pointed to perverse government policy.

High-wage policies (Hoover)

“In the AAA’s
first year,
the .supply of food
outstripped demand. The AAA could raise prices only by
paying farmers to destroy crops, milk, and livestock. To many,
it seemed shocking to throw away food while millions of
people were going hungry.”
“The New Dealers claimed
the action was necessary
to bring prices up.”

Keynesianism
vs
Monetarism
Monetarism
Historically considered: 1929-1933
A Summary view:
In 1929, the Federal Reserve
blundered monumentally in
allowing the money supply to fall.
Monetarism
Historically considered: 1929-1933
A Summary view:
Had the blundering not been
compounded by further blundering,
P would have fallen and there
would have been a short-lived
recession (18-30 months?).
Monetarism
Historically considered: 1929-1933
A Summary view:
The Hoover administration
instituted a “high-wage policy.”
Prices, which reflected high labor
costs, were also propped up.
Monetarism
Historically considered: 1929-1933
A Summary view:
The Roosevelt administration
further propped up prices through
its NRA legislation, involving crop
destruction, cartel arrangements,
and the “Blue Eagle” program.
Monetarism
Historically considered: 1929-1933
A Summary view:
The Roosevelt administration
worked through unions to prop
wages up. It was more “successful”
in blocking wage declines than in
blocking price declines.
Monetarism
Historically considered: 1929-1933
A Summary view:
All told, there was a double blunder
with a catastrophic twist:
M collapsed; P and W were propped
up--W more successfully than P.
Monetarism
Historically considered: 1929-1933
A Summary view:
The “real wage rate” (W/P) rose,
and unemployment peaked at 25%.
The Great Depression lasted for a
decade (1929-1939).
Keynesianism
MV = PQ
Keynesianism
MV = P(QC + QI)
MV = PQC + PQI
Y=
C + I
Keynesianism
MV = P(QC+QI)
Prices are “sticky downward.”
Investment suffers from a waning of “animal spirits.”
Consumption falls as the economy spirals downward.
Keynesianism
MV = P(QC+QI)
People begin to hoard money (“V” falls)
and may even become “fetishistic” in
their money-hoarding propensities.
Keynes believed that the velocity of
money was subject to dramatic and
unpredictable change.
He believed that people “hoard” money,
more so some times than others.
(increased hoarding means a decrease
in velocity.)
In extreme episodes, people may be
overcome by the “fetish of liquidity,”
the fetish often accompanying the
waning of animal spirits.
Keynesianism
MV = P(QC+QI +QG)
The government should increase the
money supply enough to offset people’s
“fetishistic” propensities and….
Keynesianism
MV = P(QC+QI +QG)
…to finance the fiscal policy (such as an
increase in government spending)
required to drive the economy back to its
full-employment level of income.
