I'm glad that Tom's message has been posted to the list. I did not
reply to his private response to me because I didn't think our
"settling" the dispute privately was as helpful as in "public." The
question I have for Tom's position is why he does not recognize the
inconsistency in his failure not to back off "one whit from the gist of
[his] message." Perhaps he needs more clarification of the misleading
nature of Keynes's changed language of macroeconomics that I explained
as having led to inappropriate economic analysis and policy
recommendations. Thus, Tom says:

Which New Keynesians have changed the meaning of saving from
non-spending to the purchase of financial assets (including bank
deposits) that supplies funds to borrowers such that increased savings
do not reduce "aggregate demand"? Which New Keynesians have recognized
the misleading nature of focusing on "broad money" rather than currency
or the monetary base as the relevant concern of a central bank? The
broad definition of money comes from Keynes. Which New Keynesians
recognize the misleading nature of the expenditure multiplier, founded
as it is on the mistaken notion that savings are a leakage from the
expenditure stream? Which New Keynesians have given up the mistaken
notion that savings are bad for an economy in the short run but good for
an economy's growth in the long run (following Robert Solow), as if the
long run is not a succession of short runs?

Sure enough, Friedman employed IS-LM framework, just as his 1968
statement that we all have become "Keynesians now" for employing
Keynes's language and apparatus would predict. Friedman also called the
/General Theory/ "a great book," the very book whose message his
life-long's work mostly sought to undermine. Any surprise that Friedman
could not be more successful? Had Friedman paid attention to Jacob
Viner's (1936) and Frank Knight's (1937) reviews of Keynes's /General
Theory/ pointing out the unhelpfulness of Keynes's changed language of
economics, he might have avoided adopting the IS-LM framework. As Viner
(1936) notes, in Keynes's book, "no old term for an old concept is used
when a new one can be coined, and if old terms are used new meanings are
generally assigned to them" while Knight observes that "familiar terms
and modes of expression seem to be shunned on principle in this book "
And yet it is Keynes's definitions of saving, capital, investment, and
money that modern macroeconomics continues to adopt, thanks to J.R
Hick's failure to take seriously the problems associated with Keynes's
new definitions.
Tom also argues:

I don't think it is as helpful to attempt to explain the price level by
the supply and demand for real balances as it is to do so by the supply
and demand for nominal balances. It is true that the quantity of money
demanded is a function of money's purchasing power (the price level).
But the Fed does not control the real quantity of money (currency). It
can control only the nominal quantity. Thus, given the demand for
nominal balances (a rectangular hyperbola demand function), itself a
function of such variables as income, interest rates, the price level,
and expectations of changes in the price level, an increase in the
quantity of money by the Fed creates an increase in the real quantity at
the existing price level (determined by the previous supply and demand
for currency). It is the attempts to reduce the quantity of money
desired to be held or currency-to-income to their previous level that
causes prices or the price level to rise. On the other, should the
public desire to increase its currency-to-income ratio from its current
level, spending on goods and services would contract and with it the
price level.
I find that the data contradict Tom's claim below:
>>>> The recession of 2008-9 was due to the Fed's failure to increase the supply of broad money
>>>> sufficiently to accommodate the public's increased demand for it.
In July 2007 the U.S. monetary base stood at $821,830 million and rose
to $2,647,237 million by June 2011, an increase of 222% while M2 that
stood at $7305.6 billion in July 2007 rose to $9111.4 billion, an
increase of 24.7%. I consider the Fed's credit (money) creation to have
been rather reckless. Moreover, there was not a rush on banks by the
public to demand cash. Someone in tune with the classical explanation
that savings are the proper source of an economy's investible or
loanable funds would not have expected the Fed to do what it did, let
alone blame it for not having responded sufficiently to the public's
demand for "broad money." If there was a freeze in lending on the
overnight Federal Funds market, as some have claimed, wouldn't the
cash-rich banks have continued to do their lending while the
cash-starved banks have curbed theirs? Wouldn't the economy as a whole
have been trading with the available savings? I think it's Tom's
adoption of Keynes's language that leads him to take his incorrect
position regarding the Fed's recent behavior.
Finally, Tom declares:
>>>> None of this invalidates my point that research employing the Keynesian
>>>> framework was, on net, a substantial advance in economic analysis, an
>>>> advance that we shouldn't throw away.
I think the Keynesian framework has been an unfortunate source of
considerable confusion in macroeconomic analysis and policy
formulation. Besides, Tom's cited hero, Paul Krugman, is hardly a
"reformed" or New Keynesian, or is he? I think N. Gregory Mankiw is on
his way out of the Keynesian confusion when he discusses the six
"dubious" Keynesian propositions in his /European Economic Journal/
article, praising David Hume's monetary analysis.
