The Failure of the "New Keynesian"


Nobel Prize Economist and New Keynesian Paul Krugman has a very bad discussion on Hazlitt.

Jeremy Hammond completely destroyed him in this great article. He even shows an old 1987 article in which Krugman blatantly refutes himself. Hammond perfectly points out that “[N]either does Krugman by any coherent and clear-cut argument refute the logic by which Hazlitt concluded that eliminating minimum wage laws would have benefited workers by allowing them to gain employment during the Great Depression. He simply declares Hazlitt “wrong about everything”, cites an irrelevant quote from Keynes, and then goes on to cite Irving Fisher to bolster his assertion that following Hazlitt’s advice would have made things “worse” and the “overall effect” would have been “to deepen the depression.””

I will show evidence that Krugman either never read Hazlitt or, if he did it, he deliberately misled his readers. In other words: either he is an ignorant talking about an author he never read or he is a dishonest person.

Krugman writes:
“Anyway, Bartlett focuses largely on the malign influence of Henry Hazlitt, who was among other things writing many editorials for the New York Times, always insisting that the answer to the Great Depression was to encourage big cuts in wages.”
However in his devastating and complete refutation of Keynes' book, Hazlitt wrote:

“Now in a free (non-statist, non-socialist, non-totalitarian) economy, wages do not and cannot adjust themselves en bloc, as a unit, by some neat, fixed, round, uniform percentage. Nor do prices adjust themselves en bloc, by a uniform percentage or as a unit. Nor does production adjust itself en bloc or as a unit. In a free economy there are millions of daily adjustments of one wage-rate to another, of one price to another, of this wage-rate to that price, of that price to this wage-rate. There is constantly going on in a free economy, in brief, an almost infinite number of mutual adjustments. This is how the economy works...
But all this conflicts with the simplistic theories of Keynes. He thinks in aggregates, in averages, in abstractions which are mental constructs that have lost touch with reality. He thinks, in short, in lumps. He deals only in his own lump-concepts like average-"level"-of-wages, average-“level''-of-prices, aggregate demand, aggregate supply... Keynes cannot understand a free economy precisely because it does not consist of such lumps. Having reduced everything to averages, he cannot understand any adjustment, he is even against any adjustment, that is not a uniform adjustment of each of these averages, blocks, lumps, to the other." (my bold)
If this is not enough for you, here come the best:
It is important, finally, to point out that no real adjustments of wages or prices are ever made, upward or downward, in the flat uniform simultaneous way in which Keynes implies they are made or ought to be made.
A Keynesian statistician, relying on averages and aggregates, would declare "wages" to be in equilibrium. Yet the wage-rate of none of the four industries would be in equilibrium. The solution, for a restoration of equilibrium and full employment, would be a mutual and multiple adjustment of particular wage-rates.
Always what is relevant to economic equilibrium and full employment is the relationship of particular wages-rates to other wage-rates, of particular prices to other prices, and of particular wages to particular prices; never of averages to averages, or of the wage 'level" to the price "level." Such mathematical averages or average levels do not exist in the real world. They are mental constructs;8 they are fictions; they conceal the real maladjustments in any given economic situation, or make them appear to cancel out.
It is clear as water that Hazlitt was saying that employment will be restored if PARTICULAR wage rates go down, He is not suggesting that ALL wages must to go down. Actually the reduction must not be a big and uniform one. He even used an example to demostrate that it would be a great mistake to push down all wages to combat unemployment. Hazlitt had never said in his whole book that all it was needed to combat unemployment was that THE wages go down as Krugman makes his readers to believe.

It took me around 20 minutes to find all this just using Acrobat’s word searcher. It was that easy, Krugman also could have done it.
 

Krugman says that: “Bad ideas, it appears, are extremely robust in the face of contrary evidence.” Here he is right, bad ideas like replacing Nasdaq bubble with a housing bubble (again in 2006). But hey! He was just "joking"

This is exactly the same kind of dishonesty that made his “master” to review a german written book when he couldn’t speak german very well... see here, here and here

The Posts War: A Rejoinder Post to a Reply Post from a Post Keynesian


It looks like I have unleashed Armageddon as I thought. “Lord Keynes” (LK) has replied me here. So this post is to answer his accusations. Ok LK, let's dance. You will not break me ;)

But first three positive points from his reply:

1) He spent time in reading and writing about my post.

2) He did not insult me as much as I expected :D

3) I fully agree with him in this correction: quantitative = “quantity”. Sorry, my bad.

Now let’s answer some issues:
"If I am not mistaken, Guillermo Sanchez already acknowledges that Sraffa’s critique of Hayek on the non-existence of the Wicksellian natural rate of interest is sound."
Actually what I have said was that Mises’ theory of interest was different and (much!) better than Wicksell’s. Nobody can deny that monetary rate can be (temporarily and unsustainably) deviated from the rate that would have prevailed without the intervention of (banks creating) credit expansion necessary to cause that deviation. However that deviation has inevitably unintended consequences, and the market process that acts to return to a rate not manipulated and determined for the “real” economic situation of temporal valuations of individuals is precisely the cycle. Besides the post in which I criticised LK, had bibliography against Sraffa.
 
Let's go to a point by point response:

(1) He makes a totally false accusation. There is no “red herring”: Until this post, he did not mention the fact that Keynes was a Wicksellian when he criticized Hayek or ABCT. My point was to demonstrate that he, in his post criticizing ABCT because Hayek used natural rate, did not say anything about Keynes also using Wicksell’s natural rate; and LK did not do it (until now). That’s undeniable. Then he says that Keynes abandoned that idea, something I clearly also said in my post. Again: the point I made was that he did not mention Keynes’ “dirty” Wicksellian past; he was a natural rate theorist in exactly the same moment in which Sraffa was attacking Hayek for been a Wicksellian. So LK should have mentioned Keynes’ antecedents in at least one of his 20 blog posts (I don’t know the exact number) dedicated to criticizes another guy (Heyek) because he (along with Keynes) was using the Wicksellian concept. Did he mention that fact? No, and it is easy verifiable, just look at his posts criticizing natural rate and you will see that he did not mentioned that. So there is absolutely no red herring here.

(2) The only point to demonstrate was that LK attacked Hayek because he used Wicksell’s natural rate, but he did not attacked Keynes (until his post criticizing me) for using it in his analysis. My objective was to show his arbitrary criterion of choosing Hayek as his victim, but “forgetting” Keynes. My accusation of him using a “double standard” was based in the fact that: If you made a post attacking someone (Hayek) because he used Wicksell’s natural rate, and you do not attack other guy (Keynes) who also used it at the same time, you have been dishonest with your readers. My accusation of dishonesty from his part in those previous posts is still standing. However he confessed it in replying me.

(4) 
"The word “scarce” can have two meanings: (1) finite, and (2) insufficient quantities available in relation to demand. When I say that something is “relatively abundant,” I mean that it is available in a quantity that exceeds the demand for it."
LK did not, I repeat did not, use the words “relatively abundant”, you can look for it in the whole post and you will not find it. His actual words were: “Mises still fails to address the issue of what would happen had the factor inputs or consumer goods NOT been SCARCE.” If, in saying "not been scarce", LK is talking about factors been “available in a quantity that exceeds the demand for it” then he talks about a surplus of them, which is exactly what Mises was talking about! [“At times, even on the unhampered market, there are some unemployed workers, unsold consumers’ goods and quantities of unused factors of production, which would not exist under “static equilibrium.” (quoted and coloured by LK himself)] So that makes me wonder: What in the world was LK criticizing then? He attacked Mises for not “assuming” a surplus of factors of production when the austrian actually clearly and explicitly was doing that!

The phrase LK used (“not scarce”) can also have two meanings: (1) infinite, and (2) sufficient quantities available in relation to demand. The (2), and also (1), can actually be the definition of a free good!
"Free goods are things that exist in superfluity, that is, in quantities sufficient not only to gratify, but to satisfy all the wants that may depend on them.”[1]
This is more than a semantics problem. What is called a “free good” is actually the opposite of a scarce good i.e. an economic good (scarce in relation to its demand). When LK said “not scarce” the “not” word implies opposition, so I was perfectly right in talking about he assuming Garden of Eden. Another easily verifiable fact just looking at his post. There is no straw man here (and if you read my post you will see I "predicted" he will try to scape his own Land of Cockaigne assumption in this way), anyone can check the phrase “factor inputs or consumer goods not been scarce”. 
“But relative scarcity and relative abundance in these senses exist, and an economy can have a relative abundance of certain goods in any time outside a boom. [At times, even on the unhampered market, there are some unemployed workers, unsold consumers’ goods…]
Pay attention to what is in brackets, that is what Mises said in 1928. It is actually what LK is asserting! 

LK says: 
"Nor do I deny that as an economy expands and reaches a boom, inflationary pressures build up as resources become less available."
But he himself had said:
All that Mises does is admit the fact that capitalist economies do have idle resources, but then says that his cycle effects require that this abundance declines and the relevant factor inputs become scarce.”
If an economy with significant idle resources has investment via fractional reserve banking or central bank creation of excess reserves (without prior saving in loanable funds), how will these inflationary pressures happen if productive resources simply do not need to be freed in the stages close to consumption? Such factor inputs will be available or quickly made available through increasing capacity utilization in the relevant industries.”
“the charge against ABCT is that its cycle effects do not occur if the factor inputs and consumer goods required by expanded demand are not scarce.”
Versions of ABCT dispensing with a Wicksellian natural rate of interest fail to explain why the cycle effects would happen if factor inputs were not scarce and available through international trade.”
Does everyone notice the contradiction here? He is criticizing misesian ABCT because “his cycle effects require that this abundance declines and the relevant factor inputs become scarce” and that “its cycle effects do not occur if the factor inputs and consumer goods required by expanded demand are not scarce” and also that “The objection that an economy where factor inputs are relatively abundant still poses a serious problem to the Austrian business cycle theory”. He even ask “how will these inflationary pressures happen if… factor inputs will be available or quickly made available through increasing capacity utilization in the relevant industries?"

However later on he acknowledges that “as an economy expands and reaches a boom, inflationary pressures build up as resources become less available”. In other words he says ABCT is false because it assumes factors becoming scarce in the boom, but he asserts that in the real world factors can be not scarce. However suddenly he says that he doesn’t deny that an economy that expands in a boom will face scarcity of factors.

If Mises’ “cycle effects require that this abundance declines and the relevant factor inputs become scarce” during the boom phase and LK has admited that “as an economy expands and reaches a boom, inflationary pressures build up as resources become less available”, then Mises theory is totally correct! I have to repeat this because it is an obvious “Lord Keynes Kontradiction”.


(3) Do you think I forgot point three? Of course not! I left it to the end because is amazing. LK makes an impressive statement:
“Interest is a monetary phenomenon, not explained by time preference.”
The absolutely refuted fallacy that interest is a monetary phenomenon must be in the Top Five of the Greatest Economics Myths of all times. One of the greatest achievements of economic science was the discovery that interest is not merely a monetary phenomenon. We know that since, at least, the days of Hume. The economists had completely destroyed that fallacious explanation from the prescientific days of economic science until Keynes revived it. But as it is completely impossible to revive a person from death, all you can do is to create a zombie, and that is what Keynes did in “reviving” that old fallacy.  

That "theory" has serious problems: 1) If interest is only monetary, then we can make interest disappear lastingly only by increasing money supply offered to loans. That's all! And finally we can achieve the paradise of “gratuitousness of credit”. The fact that theoretically and in practice that is not proved at all and has never happened, is enough proof to refute such machination. 2) In thinking this way he necessarily is implicitly denying interest! 3) Interest would prevail even in equilibrium, in contrast to money. Money (as we know it) disappears in equilibrium to transform itself into a numeraire, but interest prevails as a unique-uniform-equilibrium rate. And, as Sraffa acknowledges [“I pointed out that only under conditions of equilibrium would there be a single rate… If money did not exist, and loans were made in terms of all sorts of commodities, there would be a single rate which satisfies the conditions of equilibrium...”], even in barter economy in equilibrium there will prevail a unique rate of interest (and outside equilibrium there would be "multiples", acordin to him of course). So even in a world of equilibrium there must be interest and has nothing to do with money (which does not exist as our "money") 4) Without interest there would not be maintenance or reinvestment of capital. With zero return, those things would be impossible. 5) The fact that interest is normally paid in money, is not evidence at all that it is a monetary phenomenon. Wages, profits and rent are also paid in money. As Hazlitt said: “Keynesians might go on to object that interest is paid not only in money but for money; that in this sense the phenomenon of interest is "purely monetary," and is merely to be explained in terms of the supply of, and demand for, loanable funds. This type of supply-and-demand theory, often met with in current economic textbooks, is not incorrect, but it is superficial and incomplete. When we go on to ask what in turn determines the supply of, and demand for, loanable funds, the explanation must be made largely in real terms. But Keynes explicitly denies the relevance of these real factors… It is true that interest is paid in money, and on a capital sum usually specified in money, and that therefore monetary factors have to be considered, especially when considering dynamic changes in the rate of interest. Keynes's fallacy consists in assuming that because monetary factors can be shown to affect the rate of interest, "real" factors can safely be ignored or even denied.” No respected and serious economist has ever dedicated more than a chapter or a subsection to this superficial myth.

Fisher in 1907 was certainly right in calling this a “Crude Theory” of interest. It is so superficial that can deceive man-on-the-street or a business-man, but should not deceive any respectable economist:
"A special version of the theory that interest depends on the "use of money" is found in the very persistent belief that the quantity of money in circulation governs the rate of interest, - that the rate is high when money is scarce, and low when money is plentiful. The shallowness of this theory has been exposed repeatedly by economists from the time of Hume to the present. It requires only a little reflection to see that, although an increase of the quantity of money in circulation will increase the supply of loans, it will also equally increase the demand. For instance, a piano dealer who borrows $10,000 in order that he may add to his stock in trade 50 pianos costing $200 a piece would, if the supply of money were doubled, require a loan of double the amount; for such an inflation of the currency would double the cost of his stock, and in order to obtain 50 pianos - costing now $400 apiece instead of $200 he would have to borrow $20,000 instead of $10,000. In spite of such reasoning, showing that an inflation of the currency must act on the demand for loans as surely as upon the supply, the theory that an abundance of money lowers the rate of interest is nevertheless widely accepted even among intelligent business men. Yet facts do not, any more than a priori reasoning, lend support to this belief. The probable reason for the persistence, among business men, of the opinion that an abundance of money reduces the rate of interest is the observed fact that the rate of interest is high when the reserves in banks are low, and vice versa, and that the rate in a loan center can be materially reduced by bringing to that center a supply of actual money to relieve the "stringency." This is true, and it is not denied that money plays a part in determining the rate of interest. But the part which it plays is chiefly as a puppet of other and mightier factors. The fundamental causes at work in a "money" market are not monetary at all, but economic. The economic causes operate through money and seldom show themselves save under a money disguise; but, generally speaking, money is only their instrument, not an independent factor. If money is plentiful for loan purposes, it is because its owners decide to apply it for these rather than for other purposes, and not because money in general is plentiful. The owners of money determine the purpose to which it shall be applied. To understand the real causes at work in the loan market, we must go back of the money itself and learn the reasons for bringing it into that market instead of spending it in other markets, - the meat, fish, fruit, or grocery markets, for instance. The abundance or scarcity of money for loan purposes is merely a sign or symptom of those more fundamental causes operating upon the rate of interestIn the present chapter we are content merely to point out that the theories of which it treats are crude and superficial. They contain a modicum of truth, but they do not reach the root causes of interest. It is true that explicit interest is dependent upon implicit interest; but this being so, the question still remains, What determines implicit interest? Again, it is true that the rate of interest, like every other ratio of exchange, depends on “supply and demand"; but the question, is, What constitutes the supply and demand? And again, it is true that interest varies with loanable funds; but what causes the variation of those funds?" (Italics and bold added)[2]
The fallacy is so evident that aroused the ire of Frank Knight who accused Keynes of committing a basic and foolish textbook mistake:
"Mr. Keynes bases his whole argument for the monetary theory of interest on the familiar fact that open market operations can be effective. Mr. Hicks makes the error more palpable by saying explicitly that new currency injected into an economy "at first" and "in the first instance" lowers the rate of interest, or discount, but afterwards raises prices and “therefore tends to increase discount.” But in his entire subsequent argument, Mr. Hicks assumes without qualification or reservation a definite (inverse) functional relation between the quantity of money and the interest rate. It is a depressing fact that at the present date in history there should be any occasion to point out to students that this position is mere man-in-the-street economics. The position is analytically absurd, and any respectable textbook in economics explains why. The rate of interest in its normal aspect as the rate of return on investment is the ratio between two value magnitudes, income and wealth. A change in the unit of value can affect this ratio only as it affects one of its terms more than it affects the other. There may (or may not) be such a differential effect for a time, after a monetary change. Of course if created currency is used exclusively to buy bonds, or even to construct new equipment, it can temporarily raise the relative price which the principal, or source, will yield. Such an occurrence is a temporary disturbance only. As a monetary change diffuses through the economy, it comes to affect all classes of prices in the same way, and at equilibrium any relative price will be the same as before the monetary change occurred –except in so far as in the meantime changes may have occurred in the factors which really control the price relation in question... That a monetary theory of interest should be defended by economists of repute is especially mysterious in view of the facts, which are directly contrary to what the theory calls for." (Italics and bold added) [3]
Please note that Fisher’s and Knight’s explanation assumes a uniform and proportional increment in prices as money increase, a phenomenon completely refuted by Mises (despite the fact that for those two “neoclassicals” the interest rate is affected first and before other prices are reached), but that does not affected the “essence” of their explanation.

And here is Mises:
"There were schools of thought for whom interest was merely a price paid for obtaining the disposition of a quantity of money or money substitutes. From this belief they quite logically drew the inference that abolishing the scarcity of money and money-substitutes would abolish interest altogether and result in the gratuitousness of credit. If, however, one does not endorse this view and comprehends the nature of originary interest, a problem presents itself the treatment of which one must not evade. An additional supply of credit, brought about by an increase in the quantity of money or fiduciary media, has certainly the power to lower the gross market rate of interest. If interest is not merely a monetary phenomenon and consequently cannot be lastingly lowered or brushed away by any increase, however large, in the supply of money and fiduciary media, it devolves upon economics to show how the height of the rate of interest conforming to the state of the market's nonmonetary data reestablishes itself. It must explain what kind of process removes the cash-induced deviation of the market rate from that state which is consonant with the ratio in people's valuation of present and future goods. If economics were at a loss to achieve this, it would implicitly admit that interest is a monetary phenomenon and could even disappear completely in the course of changes in the money relation… For this theory alone answers the question of how an inflow of additional money and fiduciary media affects the loan market and the market rate of interest. Only those for whom interest is merely the outgrowth of an institutionally conditioned scarcity of money can dispense with an implicit acknowledgment of the circulation-credit theory of the cycle. This explains why no critic has ever advanced any tenable objection against this theory." (Italics and bold added) [4]
Keynes’ theory was so wrong that it was refuted beforehand just some decades before by Mises himself. Here is The Lord:
"Interest today rewards no genuine sacrifice, any more than does the rent of land. The owner of capital can obtain interest because capital is scarce, just as the owner of land can obtain rent because land is scarce. But whilst there may be intrinsic reasons for the scarcity of land, there are no intrinsic reasons for the scarcity of capital. An intrinsic reason for such scarcity, in the sense of a genuine sacrifice which could only be called forth by the offer of a reward in the shape of interest, would not exist, in the long run, except in the event of the individual propensity to consume proving to be of such a character that net saving in conditions of full employment comes to an end before capital has become sufficiently abundant. But even so, it will still be possible for communal saving through the agency of the State to be maintained at a level which will allow the growth of capital up to the point where it ceases to be scarce." (Italics and bold added)[5]
I will totally pass over the obvious fact that Keynes (just like “Lord Keynes”) has just denied scarcity, to show what Mises responded to that in 1912:
"To one group of writers, the problem appeared to offer little difficulty. From the circumstance that it is possible for the banks to reduce the rate of interest in their bank-credit business down to the limit set by their working costs, these writers thought it permissible to deduce that credit can be granted gratuitously or, more correctly, almost gratuitously. In drawing this conclusion, their doctrine implicitly denies the existence of interest. It regards interest as compensation for the temporary relinquishing of money in the broader sense - a view, indeed, of insurpassable naivety. Scientific critics have been perfectly justified in treating it with contempt; it is scarcely worth even cursory mention. But it is impossible to refrain from pointing out that these very views on the nature of interest hold an important place in popular opinion, and that they are continually being propounded afresh and recommended as a basis for measures of banking policy." (Italics and bold added)[6]
and Fetter in 1927

"Interest was thought of as paid for the use of money, as land rent was paid for the use of land. But money "cannot breed money," as land can breed crops and feed flocks; money is the "barren breed of metal." Even to scholars, as well as to the populace, the price paid for the use of money (quite like that of other things) seemed to depend on the plenty or scarcity of the precious metals. Certainly this notion still is the natural, naive, popular view, coming to the surface again and again, as in the Greenback program of the 70's and 80's, in the Populist movement of the 90's, in many contemporary pamphlets sent for the enlightenment of academic economists by amateur reformers, and even promulgated by distinguished inventors and manufacturers, who are novices in economic theory." (Italics and bold added)[7]
If any doubts are left about “Lord Keynes”’ and Lord Keynes’ unrealistic Land of Cockaigne assumption, see this statement by Mises:
"Originary interest cannot disappear as long as there is scarcity and therefore action. As long as the world is not transformed into a land of Cockaigne, men are faced with scarcity and must act and economize; they are forced to choose between satisfaction in nearer and in remoter periods of the future because neither for the former nor for the latter can full contentment be attained."(Italics added)
In denying the existence of originary interest, keynesians deny scarcity. And saying that interest is just a monetary phenomenon is exactly like saying that Earth is flat.

Why did all this happened? According to LK, all this is a misunderstanding:
"Critics of my posts on the ABCT have simply misunderstood my critique. The non-existence of the natural rate of interest is one of the reasons why Hayek’s early business cycle theory is wrong. That critique applies to all Hayekian forms of the theory that use the natural rate, and even these Austrian critics are admitting this point." 
Now I must say that “critics of [his] posts on the ABCT have simply misunderstood [his] critique” because of his own writings! I have already shown in my post that he criticized the whole ABCT (not only “Hayek’s version”) because “it is using Wicksells natural rate”, so here we go again: 
And Austrian business cycle theory (ABCT) also employs the Wicksellian concept of the natural rate of interest. With the invalidity of the concept clear, it follows that ABCT is also invalid. I will have more to say about this in future posts.”
Where is Hayek’s name or reference in the whole post from where I got that extract? 


In the post showing all “versions” of ABCT (Hayek’s included of course) he said:  
"They are all subject to these flaws: (1) They assume a single real natural rate that does not exist in a growing, money-using economy..."
This is a false statement in a double way: 1) Mises' fully development of ABCT is not based on a single natural rate. 2) About different versions of ABCT, LK has said that all they are subject to Sraffa critique of a single natural rate. He did not said that only Hayek’s “version” is subject to that critique. 

In other post “criticizing” ERE he said. 
"Yet ABCT requires a single natural rate of interest in the real world for the market/bank rate to coincide with, in order that we can avoid the cycle effects allegedly caused by ABCT."
Once again there is no signal of “Hayek’s version” of the ABCT in the whole post. He said that the whole theory requires a single rate. There is no reference to Hayek. He was forced to try to clarify that in the comment section: “ABCT, in the versions propouned by Mises (2009 [1953]: 349–366; Mises 2006 [1978]: 99ff.) and Hayek (1931) uses Wicksellian monetary equilibrium and the natural rate of interest concept.”
  
It must be obvious that in various occasions he said that all ABCT used one single-barter-Wicksellian rate and he did not clarify that he was referring to Hayek’s “version”. The “misunderstandings of his critiques” are, in some extent, LK’s own fault.  However I must say in his defense that he had clarified that his critiques apply to Hayek's "versions", or others that use "natural rate of interest in Wicksellian fashion", in many other occasions.

Let me end this post with an excellent quotation of Hazlitt
"No doubt Keynes's "system" owes part of its popularity to the impression that he has at last provided not only that Economics of Abundance, of which the Utopians have been dreaming from time immemorial, but has combined with it a Conspiracy Theory according to which the Moneylenders keep everything scarce in order that they may continue to receive Interest. But if everybody could have Complete Abundance of everything simply by ceasing to "keep capital scarce," then this Conspiracy must certainly be the most stupid and pointless in history. Did Keynes seriously believe all this?"[8]
PD: Just for the record, I did not say that Hayek’s presentation of ABCT is flawed. I think his reply is a total refutation of Sraffa’s evident misunderstanding of the theory he was trying to criticize. What I did was to show that misesian theory is totally immune to the italian critiques.

PD2: What about that marxists do not deny scarcity?


A quick search demonstrates that, starting with Marx himself, this is not totally true:

In a higher phase of communist society” there will be so abundance that the society can “inscribe on its banners: From each according to his ability, to each according to his needs!” 
 
As Boettke and Leeson says:
"The socialists informed us that by rationalizing production and thus advancing material production beyond the bounds reachable under capitalism, socialism would usher mankind into a post-scarcity world… In short, the writings of Marx and other socialists were concerned (in part) with demonstrating the productive inferiority of the  capitalist system relative to what socialism could achieve.  The organization of production under capitalism still reflects the  “kingdom of necessity,” but the social  organization of production under socialism will deliver mankind into the “kingdom of  freedom” where, through rationalization of production, scarcity will be overcome."[9]

Sraffallacies: A Misesian Defense of ABCT (II)



Mortal Kombat VS Screen Image source for the two blog-parts: 
Ok, I'm back in another lengthy post ending this issue (for now). In Part I we saw how Mises’ writings can be used to destroy Sraffa’s criticism of Hayek’s development of ABCT. Let’s continue this Mortal Kombat style post with some complementary issues.

Fatality:
Was Sraffa even right?


1. Hazlitt refutation

According to Hazlitt, Keynes’s “own rates” (based on Sraffa’s critique of Hayek) theory is false: He calls interest to the margin of a purchasing-selling transaction and from that transaction you obtain a profit (not an interest!) because you knew better than others when buy and at what time sell. It is what is obtained by “speculative anticipations of price changes”. But interest is obtained because of lending-borrowing transaction, someone lend money and pact to receive an interest payment in a future date, and some other borrow. Note that somebody is creditor and somebody is debtor. But in a purchase-selling transaction nobody lend what he sells and nobody borrows what he has purchased! The margin in a buying-selling transaction is profit, not interest. This is just a very short and bad explanation of Hazlitt insightful critique, in order to understand his argument see Hazlitt, Henry. The Failure of the "New Economics" (1959) pages 236-252. Also important is Frank Fetter’s development of the theory of time preference and the important comments of Jeffrey Herbener. Herbener's bibliography and audio/video conferences make important contributions to understand interest theory. For example in this video starting at minute 10:00 he makes important comments on “Temporal Value” (temporal use or placement), forward-spot prices, futures markets and “Intertemporal Value”, money, insolation of time preference element, natural rate, etc. They are very useful in a more profound critique of Sraffa’s concept.

2. Conard’s analysis

Conard in Introduction to the Theory of Interest (1959) chapter VIII gives an example of three goods (money, food and clothes) and three supposed “different” rates (4%, -20%, 30%) and he says:
"The first point to note is that in the most fundamental sense this illustration does not reveal three rates of interest, but rather three ways of describing a single rate of interestThe issue is not what one borrows or lends, but rather by what measuring stick one evaluates the result of borrowing or lending… Thus the difference in own-rates, which will normally exist even in full equilibrium, does not represent fundamentally different rates on the different assets, but arises instead from the fact that these rates are all measured in different standards one from another." (Italics and bold added)
The important issue is that, even in equilibrium, it is not true that there are different interest rates, but there are different standards to measure the same interest rate.
 
His conclusion is:
"(1) With given and uniform expectations the rates of interest on different commodities are identical in equilibrium, provided only that they be measured by the same standard. (2) Differences in own-rates may well exist, even in equilibrium, but these differences arise, not because the rate on X differs from the rate on Y, but only from the fact that own rates measure the rate on X by one standard (i.e., relative to X) and the rate on Y by another standard (i.e., relative to Y)."
Even in equilibrium, differences in rates arise not because there are different rates of interest, but due to the fact that the standard which we use to measure it might be different. It is the standard chosen what yields different results, not the rate of interest. With a further elaboration, this analysis could be also another refutation of the thesis of the italian. It is a very good chapter to understand the debate and the argument of Hayek's response to Sraffa.

 3. Cwik’s clarification and refutation
  
Paul Cwik (one of my favorite austrians alive today) has an incredible good paper defending Austrian theory of time preference from “inside” criticism. In “A Defense of the Traditional Austrian Theory of Interest” (2003) he defends the “traditional” theory from the attack of almost all other Austrians like Hülsmann, Reisman, etc. And also from Robert P. Murphy who has attacked austrian theory of time preference with a similar argument as Sraffa. He also makes and important contribution in clarifying that Böhm-Bawerk did not necessarily contradicted himself in accepting some productivity explanations on the determination of the real world rate of interest (which is different from the phenomenon of origin of interest alone):
“Murphy is being uncharitable and is attacking a straw man. Of course, when the assumption of ceteris paribus is relaxed, the interest rate is not a single and uniform rate. This is evidenced in the real world by the various structures of interest rates, e.g., the term structure of interest and the risk structure of interest. Murphy confuses the functionalist implications with the essentialist formulation of interest. The ERE is supposed to be an abstraction from the real world. The ERE is not designed to examine multiple structures of rates. Furthermore, the use of the simplifying assumption of a single interest rate does not disprove the traditional Austrian theory of interest… The formation of market interest rates is the result of the combination of the following: time-preference, the productivity of capital, changes in wealth, changes in expectations, the length of time to complete an investment project, risk of default, liquidity assessments, inflation, information costs, and institutional factors. Timepreference is endogenous to the action of individuals, while the other factors are exogenous and simply modify the market rate of interest… In a single interest rate market, all the exogenous factors are initially held constant…” (Italics and bold added)
 4. Lachmann’s refutation

He confronts the debate between Sraffa and Hayek directly in his books Capital and Its Structure (1956) pages 75-77 and in his 1986 article “Austrian Economics Under Fire: The Hayek-Sraffa Duel in Retrospect” included in the book Expectations and the Meaning of Institutions (1994). He developed an “overall equilibrium of interest rates” which is neither Sraffa’s nor Hayek’s type: “What Hayek should have said is not that there might be as many rates of interest as there are commodities all of which would be equilibrium rates, but that only some of them would be. While overall equilibrium requires equality of demand and supply in each single market, the latter is not a sufficient condition of the former.”

 5. Murphy’s refutation

Robert P. Murphy’s great paper “Multiple Interest Rates and Austrian Business Cycle Theory” (2010) takes the subject directly as Lachmann did. The enormous merit of this paper is that even if Sraffa was right, his critique does not refute ABCT. In other words he was able (after criticizes Lachmann’s solution) to ensure the validity of ABCT in Sraffa’s own terms (a multiple rates environment). ABCT is still valid even in the circumstances in which Sraffa said it would not be valid. He managed to do it using a Dynamic Equilibrium simple model. Maybe the best refutation is not to demonstrate that Sraffa was wrong, but to demonstrate that even if he was right, the theory still holds logically:
“However, as our last scenario above hoped to convey, it still is true that an intertemporal, dynamic equilibrium can be disturbed if commercial banks inject new money into the credit markets. If a Misesian boom-bust cycle ensues, the reason is not that the banks charged a money right below “the” natural rate, because there is no such thing. Yet the basic Misesian analysis still holds true, that the bankers have suddenly augmented the purchasing power of one segment of the population, which not only redistributes real wealth but also leads to distorted money prices and more mistakes than otherwise would have occurred.” (Italics and bold added)
And even accepting Sraffa’s criticism and thesis, Murphy is very smart in acknowledge that Mises was perfectly aware that outside equilibrium there is not a unique rate:
“In its canonical form (e.g. Mises 1998 and Rothbard 2004), Austrian business cycle theory (ABCT) has focused on the distortions in the structure of production introduced by lowering “the” market rate of interest below “the” natural rate. To be sure, Mises and his followers are aware that in the real world, there are a multiplicity of interest rates, depending on the length of the loan and the perceived risk of default… Although Misesians acknowledge the fact that the real, or natural, or originary, rates of return could be different among different commodities in the real world, they typically ascribe these differences to uncertainty and entrepreneurial profit or loss." (Italics added)

Brutality:
A blogger criticisms


A blogger called “Lord Keynes” (nobody knows his real name, maybe it’s John Maynard’s spectre blogging from underworld to take revenge from austrians) is a famous post-keynesian commenter in libertarian-austrian blogosphere, forums and internet pages referring to austrians. He (she?) actually has a complete blog only to “refute” and attack every idea an austrian economist has ever had (he also writes about post-keynesian economics, philosophy and other things that are of no importance right now). Of course this is not a bad thing, a good theory or school must always be subject to attack in order to reinforce its soundness. He is not the only one post-keynesian internet blogger who criticizes austrians (Robert Vienneau for example is another), but he is certainly one of the most active. He also has a direct, rude and impolite style to communicate that I like but may bother other people, however I know perfectly that he is wrong a lot of times on what he says, and also his blog is a very good source of bibliography in some austrian subjects. After having flattered him too much, here comes the ugly job. 

Having declared the “victory” of Sraffa over Hayek, he has some other criticism of ABCT. Let’s see some.
 
After having no choice but to admit that Mises later on was not using the Wicksellian “natual rate of interest” theory, he says:
“But, as late as 1928 in Monetary Stabilization and Cyclical Policy, Mises is still using the Wicksellian natural interest rate:…To the extent that Mises’ presentation of ABCT in the Theory of Money and Credit and Monetary Stabilization and Cyclical Policy (1928) relies on the Wicksellian natural interest rate concept, it must be judged as worthless as Hayek’s Prices and Production.”
We have seen that Mises did use, but did not necessarily approved or was in agree with, Wicksell’s natural rate terminology. Later on, when he finally could, he developed his own theory very different from Wicksell's. However (following LK own argument) as the (post)keynesian he is, “Lord Keynes” does not mention the fact that Mises was not the only one whose theory relied on the wicksellian natural interest rate concept. Keynes himself confessed that he also relied on it on the same time (early 30s) that Sraffa accused Hayek of using that unique rate concept:
"In my Treatise on Money I defined what purported to be a unique rate of interest, which I called the natural rate of interest — namely, the rate of interest which, in the terminology of my Treatise, preserved equality between the rate of saving (as there defined) and the rate of investment. I believed this to be a development and clarification of Wicksell’s “natural rate of interest”, which was, according to him, the rate which would preserve the stability if some, not quite clearly specified, price-level…” “I am now no longer of the opinion that the concept of a “natural” rate of interest, which previously seemed to me a most promising idea, has anything very useful or significant to contribute to our analysis. It is merely the rate of interest which will preserve the status quo; and, in general, we have no predominant interest in the status quo as such." (Italics and bold added)[1]
As everybody knows, in the early 30s (and before that) Keynes was a wicksellian and a quantitative theorist:
"From his early book on Indian Currency (1913) to the Tract on Monetary Reform (1923), Keynes remained a Quantity Theorist in the Marshal1ian Cambridge tradition mainly concerned with questions of how to regulate the supply of money, how to stabilize the monetary liabilities of a fractional reserve banking system against inflows and outflows of international reserves, and how to structure the international monetary system so as to minimize such problems. Much of the Treatise on Money (1930) deals with these same problems. In fact, the Treatise as a whole is very much a work still recognizably in the Quantity Theory tradition, despite its emphasis on problems of the short run. Here, however, these older themes are left aside to focus on the novel ideas of the work: the first Keynes variation on Wicksell's theme." (Italics and bold added)[2]
"Keynes’s starting position in the late 1920s is harder to define, since his ideas were in flux. It is difficult to talk of a distinctive Keynes model, since he had not yet developed a theory of output. His two pre-Depression theoretical books can be read as explanations of the tendency for economies to experience deep price fluctuations, using the quantity theory of money as his analytic framework." (Italics and bold added)[3]
"Nevertheless Keynes allows that there is something in common between their conceptions – namely the Wicksellian/Marshallian theory of macroeconomic fluctuations as resulting from a discrepancy between the ‘natural’ and the ‘money’ rates of interest. Keynes accepts Hayek’s comment that he does not explain (amongst other things) ‘the factors which determine the natural rate of interest’ and agrees with Hayek that ‘a clear account of the factors determining the natural rate of interest ought to have a place in a completed Treatise on Money, and that it is lacking in mine . . .’ Note that at this point Keynes, evidently still thinking in terms of the model of the Treatise, has no difficulty with the concept of the natural rate… Did this discovery by Sraffa of a new concept of interest contribute to Keynes’s intellectual progress from the Treatise to the General Theory? His views on interest certainly altered soon after the Hayek interlude. We have noted that in late 1931, when responding to Hayek’s review of the Treatise, Keynes was apparently still quite comfortable with the traditional notion of the existence of a unique natural rate with which the money rate of interest needed to accord to ensure that savings passed to investment. Yet it is clear that within a year, at least by autumn 1932, when he resumed his university lectures, Keynes had formulated the essential, and fundamentally revolutionary, structure of the General Theory." (Italics and bold added)[4]
Why did “Lord Keynes” accuses Mises (or Hayek) of using Wicksell’s natural rate and did not say anything about Keynes who was using it too two years after Mises and at the same time that Sraffa was accusing Hayek of using that wicksellian concept? Has he the guts to refute his “master"’s Treatise and his previous books because he was using the wicksellian natural rate concept? Can LK write “Keynes's early theory is a complete nonsense because he relied on wicksellian theory of natural rate of interest” or “All Keynes’s pre-GT writings on monetary and interest theory are worthless because he relied on wicksellian natural rate”? I doubt it. But let’s assume LK admits it and says “yes, all what Keynes wrote before GT is garbage because he relied on Wicksell natural rate. But obviously later on he did not used that faulty concept.”, however he himself has confessed that Mises in his later treatments abandoned that concept too. So in order to be intelectually honest he must say that Mises-ABCT is as immune to Sraffa’s criticism as it is the monetary and interest theory of Keynes in GT (Of course, as demostrated above, originary interest is not Wicksell’s natural rate).

Actually we can very easily use his own accusation and his own words on Mises against Keynes himself: “But, as late as 1930 in A Treatise of Money, Keynes is still using the Wicksellian natural interest rate:…To the extent that Keynes’ theory in the A Treatise of Money (1930) relies on the Wicksellian natural interest rate concept, it must be judged as worthless."[5] 

The question is: Can someone raise such accusation in front of a keynesian? Of course not. Because immediately the keynesian would say: “But Keynes after in his GT abandoned Wicksell’s idea”, which is true. But the same true is valid for Mises in his later Human Action (a fact, I repeat, LK admitted!): His interest theory is not about a barter-equilibrium-unique in real world-rate. The fact that LK was unable (either by ignorance or deliberately) to use his own accusatory arguments against Keynes (who was also using wicksellian “natural” rate) demonstrates that his “critique” is arbitrary and totally invalid. He has an arbitrary and selective criterion which distorts this criticism and probably others.

LK also says:
"And Austrian business cycle theory (ABCT) also employs the Wicksellian concept of the natural rate of interest. With the invalidity of the concept clear, it follows that ABCT is also invalid."
This is a false statement as I demonstrated in Part I. But even if it were true, then: “Keynes' monetary theory in his most important book in 1930 also employs the wicksellian concept of the natural rate of interest. With the invalidity of the concept clear, it follows that Keynes’ monetary theory of early 30s is also invalid” Once again the arbitrary is present: Why, if Keynes was also using Wicksell’s natural rate, LK did not apply his criticism on his "master"? His arbitrary rule of “I attack austrians, but "forgetting" applying the same criterion on Keynes” must be obvious now. It is a question of basic logic: If ABCT is invalid because it uses Wicksell’s natural rate, then Keynes’s monetary and interest theory of 1930 and 20s is also invalid because it uses Wicksell’s natural rate. The fact of not saying anything about Keynes and attacking austrians demonstrate LK's arbitrary and selective criterion. Arbitrariness is not science at all. This is an evident example of double standard, coming from a guy who accused others of having a "double standard". 

Let’s see other examples: 
“I have recently seen this attempt to defend Mises’ early versions of ABCT, by invoking his later concept of the “evenly rotating economy”/stationary economy concept: But a reading of the earlier work of Mises in works cited above does not support this: (1) There is not one reference to the concept of the “evenly rotating economy” (ERE) in The Theory of Money and Credit(trans. J. E. Batson; Mises Institute, Auburn, Ala. 2009 [1953]). On pages 349–366 where Mises sets out his trade cycle theory, he uses the Wicksellian natural interest rate concept and Wicksellian monetary equilibrium analysis. (2) There is not one reference to the concept of the “evenly rotating economy” in Monetary Stabilization and Cyclical Policy (1928), and again Mises is still using the Wicksellian natural interest rate (p. 99ff.)."
Did you spot the fallacy? Let’s rewrite that “critique”: 

"I have recently seen this attempt to defend Keynes’ early versions of his theories based on Wicksell natural rate, by invoking his later concept of the “own-rate of interest”: But a reading of the earlier work of Keynes does not support this: (1) There is not one reference to the concept of the “own-rates of interest” neither in The Economic Concecuences of Peace (1919) nor in his Tract on Monetary Reform (1924) . As he has himself confessed, in his 1930 book, where he sets out his monetary theory, he uses the wicksellian natural interest rate concept and wicksellian monetary equilibrium analysis. (2) There is not one reference to the concept of the “own rate of interest” in The Treatise of Money (1930), and again Keynes is still using the Wicksellian natural interest rate."

Using his arbitrary criterion again over Keynes, I can demonstrate how ridicule is to accuse someone of had not written something he was only able to write on a later date. But of course for LK applying that criticism to Austrians is fine, but applying it to Keynes would be ridicule. 

And then he says:
"Yet ABCT requires a single natural rate of interest in the real world for the market/bank rate to coincide with, in order that we can avoid the cycle effects allegedly caused by ABCT."
False: a) ABCT does not require a single natural rate of interest in the real world. b) ABCT does not require the market/bank rate to coincide with it. 

About Mises’s “originary” interest rate he says:
"But this is really just another real theory of the interest rate where loans are imagined as occurring in natura, or in real commodities in an economy at full employment. Mises is still subject to Sraffa’s critique of Hayek."
This is not true at all. The “real factors” in Mises theory are not real commodities, but are subjective valuations in different points of time (ceteris paribus) in a money economy. It is based in ordering ends to be attained in different points of time. As well as marginal utility theory is based on ordering ends, not goods. In the sacks of grain example of hm-Bawerk, the person is not ordering sacks of grain (all sacks are equal) but the ends he can attain with more or less sacks. Even the quote he uses to affirm that false statement demonstrates it: “Originary interest is the ratio of the value assigned to want-satisfaction in the immediate future and the value assigned to want-satisfaction in remote periods of the future. It manifests itself in the market economy in the discount of future goods as against present goods. It is a ratio of commodity prices, not a price in itself..." (Italics added)

"Lord Keynes" also makes a recount of “different versions” of the ABCT. Is it bad to have different “versions” of a theory which was developed by different people and which is more than 100 years old? Not at all. And about the "versions" he says:
"They assume a single real natural rate that does not exist in a growing, money-using economy, as Sraffa showed (1932a and 1932b). The natural rate is one that would obtain, as if loans were made in natura (that is, in real commodities). But in a barter economy not in equilibrium, there could be as many natural rates as there as commodities."
False: A “growing, money-using economy” is a changing economy and actually, if there is money, it must be a changing economy (in ERE there is no demand for money and it is just a numerarie as Mises has shown). It has been demonstrated that in a changing monetary economy there is no-unique, no-single, no-barter rate either of originary or gross market interest. After this comes:
“(2) In Hayek’s version of ABCT in Prices and Production(London, 1931) he argued that policy should attempt to make money neutral (although by 1933 he was questioning whether monetary policy could ever approach the situation of “neutral money” [Hayek 1933: 159-162]). But money can never be made neutral, and a state in which money is neutral is nothing but a state in which money does not exist."
It is an undeniable fact that Mises did not under any circumstance looked for a “neutral money” ever, the whole concept is contradictory. The ABCT does not look for either a “neutral money” or a “policy to target any natural rate”. The very foundation of the theory is the non-neutrality of money, the theory needs the non-neutral effect of money in order to be true. I'm sure LK will try to answer “Don’t be an idiot! I’m referring to (Sraffa’s interpretation of)Hayek’s version of ABCT in that sentence!” But “Hayek’s version”, is not THE whole ABCT, so LK could not have claimed in other place “With the invalidity of the concept clear, it follows that ABCT is also invalid”. He said that ABCT is invalid, not that Hayek's version of ABCT is invalid.

The accusation of “assuming full employment” has been refuted so many times by so many austrians that I can’t believe I’m dedicating space here for it. But there is something interesting: After been obligated to accept the obvious fact that Mises in 1928 (yes! before Keynes’s General Theory!) was writing about and even assuming unemployment, all that LK can do is to deny scarcity!!!
"Mises still fails to address the issue of what would happen had the factor inputs or consumer goods not been scarce."
As well as socialists and technocrats, keynesians like to deny scarcity or put the blame on an artificial scarcity created by someone. This is a kind of “Land of Cockaigne" assumption or "post-scarcity society". It is not a surprise coming from someone whose master said: "I am myself impressed by the great social advantages of increasing the stock of capital until it ceases to be scarce." 

But ok, let’s ask the austrian: What would happen if the factor inputs or consumer goods are not scarce?   
"Labor is the most scarce of all primary means of production because it is in this restricted sense nonspecific and because every variety of production requires the expenditure of labor. Thus the scarcity of the other primary means of production—i.e., the nonhuman means of production supplied by nature—becomes for acting man a scarcity of those primary material means of production whose utilization requires the smallest expenditure of labor.”… “We may try to imagine the conditions within a world in which all material factors of production are so fully employed that there is no opportunity to employ all men or to employ all men to the extent that they are ready to work. In such a world labor is abundant; an increase in the supply of labor cannot add any increment whatever to the total amount of production. If we assume that all men have the same capacity and application for work and if we disregard the disutility of labor, labor in such a world would not be an economic good. If this world were a socialist commonwealth, an increase in population figures would be deemed an increase in the number of idle consumers. If it were a market society, wage rates paid would not be enough to prevent starvation. Those seeking employment would be ready to go to work for any wages, however low, even if insufficient for the preservation of their lives. They would be happy to delay for a while death by starvation. There is no need to dwell upon the paradoxes of this hypothesis and to discuss the problems of such a world. Our world is different. Labor is more scarce than material factors of production. We are not dealing at this point with the problem of optimum population. We are dealing only with the fact that there are material factors of production which remain unused because the labor required is needed for the satisfaction of more urgent needs. In our world there is no abundance, but a shortage of manpower, and there are unused material factors of production, i.e., land, mineral deposits, and even plants and equipment.”… “As long as the world is not transformed into a land of Cockaigne, men are faced with scarcity and must act and economize Scarcity of factors of production means that we are in a position to draft plans for the improvement of our well-being the realization of which is unfeasible because of the insufficient quantity of the means available. It is precisely the unfeasibility of such desirable improvements that constitutes the element of scarcity”… “The economists were and are still today confronted with the superstitious belief that the scarcity of factors of production could be brushed away, either entirely or at least to some extent, by increasing the amount of money in circulation and by credit expansion.”… “As far as natural conditions come into play, competition can only be “free” with regard to those factors of production which are not scarce and therefore not objects of human action. There the economic problem is to employ these factors in such a way that no unit of them should be used for the satisfaction of a less urgent need if this employment prevents the satisfaction of a more urgent need”… “The available supply of every commodity is limited. If it were not scarce with regard to the demand of the public, the thing in question would not be considered an economic good, and no price would be paid for it. What slows down technological improvement is not the imperfect convertibility of capital goods, but their scarcity. We are not rich enough to renounce the services which still utilizable capital goods could provide.”… “Originary interest cannot disappear as long as there is scarcity and therefore action.”… “The characteristic mark of production activities in the past and in the foreseeable future is that the scarcity of labor exceeds the scarcity of most of the primary, nature-given material factors of production. The comparatively greater scarcity of labor determines the extent to which the comparatively abundant primary natural factors can be utilized. There is unused soil, there are unused mineral deposits and so on because there is not enough labor available for their utilization.”… “The layman and the pseudo-economist fail to recognize this fact. They stubbornly refuse to notice the scarcity of the factors of production" (Italics and bold added)[6]
First fallacy: Mises actually did address the issue if a resource, like labor, is not scarce or if goods are non scarce. It must be emphasized that Mises did not “assumed full employment”. Actually he wrote assuming unused capacity and unemployment of labor even before Keynes did ever published his first important monetary book and when, according to Skidelsky, the english economist was still assuming full employment in his own analysis. Yes, there can be unused resources and labor in real world, but Mises would never use an unrealistic assumption such as deny scarcity i.e. say that “resources and goods are not scarce”. Note that the comment of LK goes far beyond than assuming idle resources, he is not comfortable with that assumption that Mises actually did. He writes about an abundance of all resources in all sectors. But even if there is such abundance, through credit expansion we must necessarily reach a point in a time in which complementary factor of production are employed. So far Mises' assumption is correct. However LK is assuming they never become scarce, they are “not scarce”.

Before we continue we must know: What the heck is full employment for Lord Keynes? "the US economy did not return to full employment for nearly a decade after 1893." According to his post in 1892 unemployment was 3.72% and in 1900 it was 5%. “What is frequently forgotten is that an economy mired in high involuntary unemployment, even if it has growth, is in an underemployment disequilibrium. The US from 1893 to 1899 was clearly such an economy. “ So for him an unemployment rate below or at 5% is full employment. Why not 5.01%? Or 5.1%, 5.3%, 6%, 4.9%, 4%, 3%...? 

It must be no surprise for anyone that the keynesian full employment goal is, as Robbins noted, inflationary, disequilibrating and contrary to liberties. But even assuming we can “define” full employment in a non-arbitrary and non-subjective way (which is not the case) and we arbitrarily choose one of all definitions(a definition which also changes according the times), if “had the factor inputs or consumer goods not been scarcethen how in the world are we going to "full employ" something which is not scarce? How are we going to achieve a goal, say 5% of unemployment, if there is an unlimited abundance (i.e. no-scarcity) of something? Remember that “daddy state” must assure full employment, so even if we could down the unemployment rate to 5%, given the fact that labor is no scarce, after that there would be an avalanche of new workers looking for employment pushing up the unemployment rate. Then the “all mighty” state would try to push down the rate one more time but, because there is no scarcity of laborers, there will be another tsunami of them coming to be employed. And we can do this forever because there will always be workers unemployed due to the fact that they are not scarce. Actually that explanation was also unreal because in an environment of non-scarcity of labor we could not even down that rate for a single moment: imagine you want to “full employ” some good which is not scarce, like air, by putting it in empty bottles. Employment would mean: air inside the bottle. Air (the not scarce resource) would be “employed” by occupying space in the empty bottle. Even if you fill out (i.e. give an “employment”) 1 billion bottles, you are not even close to full employ that non-scarce good. Not to mention to reach some 5% goal.  Even in “Lord Keynes”’s terms, that assumption of “no scarcity” of resources destroys his long-awaited full employment goal, because he cannot reach it! 

This post is not the place to show how wrong keynesians are on the issue of “idle resources”, but assuming abundance of goods and resources as “Land of Cockayne” is definitively a non-real criterion to operate. 

Mises would not make such nonsense as to assume that resources are not scarce. If there are unemployed resources and you force economy to employ them, then they must be limited, and that would mean they must reach a limit i.e. they are scarce. If you can never reach a limit, then you are assuming a continuous never ending stream of resources and that means you are in Land of Cockayne, a totally unreal assumption. Actually in denying scarcity not only you deny economics itself, you open the door to a lot of things to happen: In such world even socialism can work! 

He will probably try to escape the consequences of his own unreal assumption by saying “I did not meant an unlimited quantity of resources and goods.” But, yes he did! He was not talking about “unemployed factors” (because that would mean to give a victory to Mises’s 1928 comment), he actually said they are “not scarce”. Not-scarcity is a very strong concept because it means unlimited abundance from the point of view of acting man[7]. And worse than that, it means assuming that unlimited abundance is a common circumstance of the world. This is false: Unemployment of some factors and some economic goods (due to errors of past or because of the never ending change of valuations and circumstances) is a characteristic of a changing world, but the “not-scarcity” of all resources is not. Actually even if we interpret his words as a “massive idleness of all factors of production” it is not true at all that that is a characteristic mark of real economy. It is instead an specific feature of a depression situation, actually the deepest point of it, a situation bringed by a credit expansion policy. In that case LK's theory is thus just a "particular theory" (not a general one) or a "special case" (of the ABCT).   

In analyzing Huerta de Soto’s argument about the process of saving, he commits a great mistake. First he says: 
“The fatal problem underlying this analysis is that capitalist systems have historically had many periods when they are mired in underemployment equilibria where there are significant idle resources, like labour, raw materials, capital goods and other factor inputs.”
Only a month later he admits that Mises in 1928 was perfectly aware of what LK himself has asserted:
All that Mises does is admit the fact that capitalist economies do have idle resources, but then says that his cycle effects require that this abundance declines and the relevant factor inputs become scarce.” (Italics added)
In other words LK is saying that capitalism had had unemployed factors, which is exactly what Mises, in explaining his theory, had said in 1928!!!  

More important than that, HdS is explaining how a sustainable process of saving “liberates” resources to be invested because it is based on reducing consumption. But the spanish guy clearly explains, later in his book, that idle resources came up due to the fact that consumption is too high! “that capitalist systems have historically had many periods... where there are significant idle resources, like labour, raw materials, capital goods and other factor inputs.” is due to the fact that there was an excessive consumption relative to savings, but HdS is explaining a process in which consumption is falling relative to savings. They are two different situations (in one consumption is falling relative to savings and in the other consumption is excessive to savings), so there is no “refutation” at all.
"Many economists have misunderstood the fact that a significant number of the errors committed manifest themselves as completed capital goods which, nonetheless, cannot be used, due to the absence of the complementary capital goods or working capital necessary. Indeed many see this phenomenon of “idle capacity” as clear proof of a necessity to boost overall consumption with the purpose of putting into operation an idle capacity which has been developed but is not yet used. They do not realize that, as Hayek indicates, the existence of “idle capacity” in many production processes (but especially in those furthest from consumption, such as high technology, construction, and capital goods industries in general) in no way constitutes proof of oversaving and insufficient consumption. Quite the opposite is true: it is a symptom of the fact that we cannot completely use fixed capital produced in error, because the immediate demand for consumer goods and services is so urgent that we cannot allow ourselves the luxury of producing the complementary capital goods nor the working capital necessary to take advantage of such idle capacity. In short the crisis is provoked by a relative excess of consumption, i.e., a relative shortage of saving, which does not permit the completion of the processes initiated, nor the production of the complementary capital goods or working capital necessary to maintain the ongoing investment processes and to employ the capital goods which, for whatever reason, entrepreneurs were able to finish during the expansion process."
In short, in LK post HdS was talking about a situation where saving is increasing i.e. consumption is falling. But LK wants to “refute” that explanation using a phenomenon (idle resources) which only occurs when there is an excessive consumption relative to saving i.e. saving is falling.  

Then comes this:
“If an economy with significant idle resources has investment via fractional reserve banking or central bank creation of excess reserves (without prior saving in loanable funds), how will these inflationary pressures happen if productive resources simply do not need to be freed in the stages close to consumption?Such factor inputs will be available or quickly made available through increasing capacity utilization in the relevant industries.” 
The response to “how will these inflationary pressures happen if productive resources simply do not need to be freed in the stages close to consumption?” (a question he raised in June 2011) was given by Huerta de Soto just a paragraph later of the extract LK used in his following post on the issue (July 2011. Of course LK did not cited it)!!!:
"When credit expansion takes place, economic projects which are not actually profitable appear so, regardless of whether they are carried out with resources that were unemployed prior to their commencement. The only effect is that the nominal price of the original means of production may not rise as much as it would if full employment existed beforehand... apart from the fact that their price does not increase as rapidly in absolute terms, they may make a short-term slowdown in the production of consumer goods and services unnecessary. Nonetheless a poor allocation of resources still takes place, since resources are invested in unprofitable projects, and the effects of the cycle eventually appear when the monetary income of the previously-unemployed original means of production begins to be spent on consumer goods and services. (Italics added)
An amazing mistake, aggravated by the fact that Rodolphe Topffer (please read his amazing post in Meng Hu) remembered that to him in the comments section and LK's response is not convincing at all. 

After that we have this phrase:
“This is another unrealistic assumption underlying ABCT: it assumes an economy with full employment, no unused capacity and no significant idle resources.”
You are not drunk, you actually have read this quote coming from the guy who tries to “refute” a theory by simply making the “very real” assumption that we live in The Garden of Eden: “what would happen had the factor inputs or consumer goods not been scarce”. Even importing them we are incredibly far from saying that “goods and resources are not scarce”. 

In other post, he says:
"In a Keynesian system, we can stimulate the economy into full employment without war or military spending. You can give a huge Keynesian boost to the economy by (1) large infrastructure spending, social spending, education spending, or increased R&D. Alternatively, you can also give a stimulus by (2) simply cutting taxes without cutting spending, which is also a classic Keynesian method." (Italics added)
Has he said that “we can stimulate the economy into full employment”? This is a false statement according to his own arguments! Because to the extent that you approach to “full employment”, that would mean necessarily that the resources you are employing are becoming scarce. His stimulus-solution explanation “requires that this abundance declines and the relevant factor inputs become scarce” insofar as we reach the “full employment” goal. "Lord Keynes still fails to address the issue of what would happen had the factor inputs or consumer goods not been scarce." Once again he has contradicted himself and also has shown his double standard.
 
After this denial of reality, LK says: 
"(4) The natural rate is conceived as an equilibrium interest rate that equilibrates loanable funds supply with demand for credit. In Wicksell’s natural rate of interest theory, this is supposed to be the interest rate where money supply is neutral, and where inflation does not occur."
Mises repeatedly said that money can not/never be neutral in real world (only in equilibrium). Here LK is saying that Wicksell's theory operate with neutral money, then this only reinforce my interpretation. If Wicksell’s natual rate is an “interest rate where money supply is neutral, and where inflation does not occur” and we have seen that the non-neutrality of money is the basic requisite for the ABCT to be true, then ABCT can not use Wicksell’s natural rate. And in the hands of Mises, ABCT does not use it!
But all these arbitrary and dishonest criticism is not just a problem of LK alone. They are in the very beginning of “sraffian economics”. Why? Because, in his exchange with the austrian economist, Sraffa did not criticized Keynes’ use of Wicksell’s natural rate concept in public debate, he only criticized Hayek’s use of it. In the same review criticizing Hayek, he could have said: “Ok Hayek’s book uses the Wicksellian natural rate which is a faulty concept, but Keynes’s book (which Hayek criticized in the first place) also relies on it, so I have my reserves”. Did he do that in that moment? No. The same book Sraffa was trying to defend from Hayek, did use the wicksellian concept of a "unique-natural" rate of interest, but the italian did not say anything about it.  

Not only Sraffa. Keynes himself was not honest enough to correct the manuscript of GT in which he confessed that he had misinterpreted Mises' and Hayek's theory of interest! Robertson in 1935 (one year before the publication of the book!) showed him that he interpreted them wrong and Keynes responded: “Thanks for the reference to Hayek which I will study. I do not doubt that Hayek says somewhere the opposite to what I am here attributing to him.” Huerta de Soto says: “Nonetheless Keynes lacked sufficient intellectual honesty to correct the manuscript prior to its definitive publication in 1936."[8] 

It may be the case that in private correspondence Sraffa expressed his opinion sincerely to Keynes or even convinced him to abandon Wicksell by 1931, but the fact that he did not do it in public debate only shows his arbitrary and dishonest opportunistic selection in order to defend the english from the austrian. That was Sraffa's criterion of “you austrian are wrong because you are based on the wicksellian natural rate. But I will not say anything about this other english-guy despite the fact he also relies on it”.  

I'm aware I will unleash a blog-war on this issue, with “Lord Keynes” making his reply blog-post probably named “Debunking an internet-austrian”, “Refuting an idiot”, “A reply to dirty Sanchez”, “A critique of a stupid-ignorant-misleading-ridicule-pathetic-strawman-false blog-post”, and names like that. But my conscience would not let me sleep if I did not publish this post attacking his criticisms.

Conclusion




Mises’s Theory of Business Cycle is totally immune to Sraffa’s 1932 criticism. It cannot be affirmed that “Sraffa refuted ABCT” because a careful examination of Mises’ writings demonstrates that he was unable to do that. Despite the obvious fact that they never confront in a direct debate, written evidence can actually be confronted. As we saw, a careful examination of Mises’s writings can be used to overcome Sraffa’s critique to Hayek (who was using Mises’s theory).

Despite the fact that Mises did use Wicksell’s terminology in the beginning of his development, due to the fact he had not neither the time nor space to develop his own ideas on the subject, he did not fully endorse that theory and in his further developments on interest subject, the austrian abandoned the sweden economist.

Contrary to Sraffa’s criticism, the interest rate that Mises developed in his explanation was not a barter-rate, was not a unique rate in the real world, there was not a policy to make money neutral and there was not a policy for the banks to target the “natural rate”. The only policy Mises recommended to avoid cycles was not to target a "natural" rate, but that banks must not expand credit (fiduciary media or circulatory credit).
