Milton Friedman On Free Trade

I always like watching Milton Friedman, not because I like him but for something totally opposite. It helps in knowing what the exact position of economists is. Milton Friedman has been hugely influential on how economists think. Almost everyone is just rambling what Friedman said, so why not listen to their master?

This is a lecture given in 1978 on free trade.

A claim made by Friedman in the video is that market mechanisms work to resolve balance of payments problems. “Balance of payments is not a problem”, says Friedman. Of course that’s all wrong but economists continue to believe in such things.

Another claim made by Friedman is that protectionism is because few industries lobby for it. While that is certainly true, how about “free trade” itself? Producers with market share in international markets influence their governments to push for free trade internationally. Why didn’t he talk of those things?

James Tobin’s papers are very interesting. I have a special liking for him even though he sometimes said strange things and used a lot of neoclassical analysis. His asset allocation theory is one of the most interesting things in monetary economics.

I came across this paper from his book Essays In Economics – Vol 1: Macroeconomics titled Money And Income: Post Hoc Ergo Propter Hoc? (also available here if you neither have the book nor jstor access).

The paper is also noted and analysed in Louis-Philippe Rochon’s book Credit, Money, and Production: An Alternative Post-Keynesian Approach (p 124 – )

In this paper Tobin takes Milton Friedman to task by constructing what he calls an “ultra-Keynesian” model which he describes as

In the ultra-Keynesian model, changes in the money supply are a passive response to income changes generated, via the multiplier mechanism, by autonomous investment and government expenditure.

(note: multiplier as in expenditure multiplier and not “money multiplier”).

For some strange reason Tobin says he doesn’t believe in this model but shows how Friedman’s empirical findings (the latter’s assertion that “changes in the supply of money are the principal cause of changes in money income Y”) are all wrong especially his assertion about leads and lags. This was also noted by Nicholas Kaldor in his 1970 article The New Monetarism reprinted in his Collected Essays, Vol 6 as Chapter 1.

… Suppose the initiating change is a decision of some firms to increase their inventories, financed by borrowing. The first impact is to cause some other firms whose sales have increased unexpectedly to incur some involuntary disinvestment. It is only when that is made good by increased orders that productive activity is expanded; any such expansion will cause higher wage outlays which in turn may involve further borrowing. The ultimate effects on income involve further changes in productive activity arising from the expenditure generated by additional incomes. There is every reason to supposing, therefore, that the rise in the “money supply” should precede the rise in income – irrespective of whether the money-increase was a cause or an effect.

So much for the various tests using Econometrics by Friedman – these don’t prove anything.

Again in his 1980 paper Monetarism and UK Monetary Policy, Kaldor states:

… the change in the money supply may be the consequence, not the cause, of the change in the money incomes (and prices), and that the mere existence of time-lag – that changes in the money supply precede changes in money incomes, is not in itself sufficient to settle the question of causality – one cannot rule out the possibility of an event A which occurred subsequent to B being nevertheless the cause of B (the simplest analogy is the rumblings of a volcano which frequently precede an eruption).

Back to Tobin. He says the following from what his “ultra-Keynesian” model:

… The main point of the exercise can be made by assuming that the monetary authority provides the bank reserves as necessary to keep r constant… The monetary authority responds to the “needs of trade”. With the help of the monetary authority, banks are able and willing to meet the fluctuating need of their borrowing customers for credit and of their depositors of money.

… The financial operations of the government and the banks are as follows: The government and the monetary authority divided the increase in debt … between “high-powered money” and bonds in such a manner as to keep the interest rate on target… the monetary authority provides enough new high-powered money to meet increased reserve requirements and any new demand for excess reserves. The remainder of the increase in public debt … takes form of bonds and is just enough to satisfy the demands of the banks and the public.

An important observation made by Tobin is that because the stock of money rises following a fiscal expansion due to a rise in income, an ultra-Keynesian

… would not even be surprised if some observers of the accelerated pace of monetary expansion in the wake of a tax cut conclude that monetary rather than fiscal policy caused the boom.

Tobin shows how “every single piece of observed evidence that Friedman reports on timing is consistent with the timing implications of the ultra-Keynesian model”.

This is quite important. Somehow most observers cannot understand the role of fiscal policy and there is almost total attention given to “what the Federal Reserve is doing or going to do” by economic commentators and “experts” of Wall Street with most comments on fiscal policy being that fiscal deficit should be somehow reduced. “We are all Keynesians now” is quite misleading because most economic commentators are heavily distorted by the quantity theory of money even though sometimes they claim to not believe in Monetarism.

Anyway, have a look at Tobin’s paper Money And Income: Post Hoc Ergo Propter Hoc?

Nicholas Kaldor On Milton Friedman’s Influence

Unlearning Economics has written a very nice post on Milton Friedman’s distortions.

It is unbelievable that people still believe in the quantity theory of money and the distortion appears to have been permanent. When Milton Friedman was rising in popularity, Nicholas Kaldor took him to task and while conceding to Kaldor that the stock of money is endogenous, Friedman still maintained the direction of causality from money to income.

One of Nicholas Kaldor’s best papers is The New Monetarism written in 1970 [1] in which he shows why the stock of money should be taken as endogenous and that Friedman’s causality is entirely incorrect. In that he also had a nice description of how Friedman’s influence was growing at the time:

… However, we now have a “monetary” counter-revolution whose message is that during this time we have been wrong and our forbears largely, or not perhaps entirely right: anyhow, on the right track, whereas we have been shunted on to the wrong track. This new doctrine is assiduously propagated from across the Atlantic by a growing band of enthusiasts, combining the fervour of early Christians with the suavity and selling power of a Madison Avenue executive. And it is very largely the product of one economist with exceptional powers of persuasion and propagation: Professor Milton Friedman of Chicago. The “new monetarism” is a “Friedman Revolution” more truly than Keynes was the sole fount of the “Keynesian Revolution”, Keynes’s General Theory was the culmination of a great deal of earlier work by large numbers of people: chiefly Wicksell and his followers, Myrdal and Lindahl in Sweden, Kalecki in Poland, not to speak of Keynes’s colleagues in Cambridge and of many others.

The new school, the Friedmanites (I do not use this term in any pejorative sense, the more respectful expression “Friedmanians” sounds worse) can record very considerable success, both in terms of the numbers of distinguished converts and of some rather glittering evidence in terms of “scientific proofs”, obtained through empirical investigations summarised in time-series regression equations. Indeed, the characteristic feature of the new school is “positivism” and “scientism”; some would say “pseudo-scientism”, using science as a selling appeal. They certainly use time-series regressions as if they provided the same kind of “proofs” as controlled experiments in the natural sciences. And one hears of new stories of conversions almost every day, one old bastion of old-fashioned Keynesian orthodoxy being captured after another:  first, the Federal Reserve Bank of St. Louis, then another Federal Reserve Bank, then the research staff of the I.M.F., or at least the majority of them, are “secret”, if not open, Friedmanites. Even the “Fed” in Washington is said to be tottering, not to speak of the spread of the new doctrines in many universities in the United States. In this country, also, there are some distinguished and lively protagonists, like Professor Harry Johnson and Professor Walters, though, in comparison to America, they write in muted tones and make more modest claims, which makes it more difficult to discover just what it is they believe in, just where the new doctrine ceases to be a matter of semantics and becomes a revelation with operational significance.

Also read Lunch With FT: Milton Friedman and William Keegan’s article written for The Observer: So Now Friedman Says He Was Wrong referring to the Financial Times article on Friedman finally conceding in 2003 that he was wrong all along.

Thanks to Philippe for pointing out some spelling errors (mine) in the quote in the previous version of this post. 

Helicopter Drops And Furnace Burns

Milton Friedman famously used helicopter drops to get money in the system as he couldn’t articulate how money is created and maintained that it is exogenously determined by the central bank or that it should be (as if!) and blurred the two.

I came across the original today – The Optimum Quantity Of Money written by him in 1969.

In addition to helicopters he also has furnaces which the government uses to burn money!

Helicopters appear on pages 4, 5, 11, 13 and 15.
