Response to Jonathan Finegold Catalán on the Austrian Business Cycle Theory

Jonathan Finegold Catalán has a response to me on the Austrian Business Cycle Theory here:
“Producers’ Goods Prices,” Economic Thought, 3 August, 2013.
First, regarding Catalán’s graphs, that movement in the prices of capital and intermediate goods occurs is not in doubt! These graphs are not necessarily showing us that prices are moving in response to demand changes. I suspect Catalán has misunderstood the meaning of “administered fixprices.” That expression does not mean prices never or rarely change.

The point is that, in administered fixprice markets, prices generally change because of changes in factor input costs, not because of short or medium term changes in demand. That should be perfectly apparent in the spikes in prices in these graphs from the mid and late 1970s, at times when the Western world was in recession, but which saw supply side inflation from the oil shocks.

These graphs do not refute my assertion about the importance and widespread existence of administered fixprices in any modern capitalist economy.

I respond to Catalán’s specific points below:
(1) Catalán says that there is “such [sc. a] thing as an equilibrium rate that we can conceptualize” (my emphasis). Yes, there is, but it is only marginally more significant to economics than the fact that we can conceptualise magical unicorns, flying dragons, or any number of other non-existent imaginary things or entities.

An imaginary Wicksellian natural rate existing only in a fictitious world of general equilibrium or Mises’s “final state of rest” is effectively worthless and irrelevant to real world economics. Why? The reason is that (1) general equilibrium cannot exist and (2) it is real rate applicable only to a barter world.

Catalán asserts that we “can use this equilibrium rate as a reference point when judging policy.” No, we cannot.

The mythical rate is irrelevant to policy. Only if Catalán posits and defends the view that the real world has a tendency towards such a rate would the natural rate have some relevance to economics. But Catalán has proven no such thing.

(2) Catalán says:
“Early versions of ABCT are movements between equilibria: Yes, LK, welcome to the world of modeling, where you abstract from certain realities to be able to focus on the aspects that you want to explain.”
But not at this level of inaccurate abstraction: Catalán wants to explain the real world by reference to non-existent transitions between equilibrium states that do not occur in the real world.

I contend that such models have no worthwhile application to the real world in explaining real world business cycles.

(3) With Austrian capital theory, we are back to the question of unrealistic “ideal types” and models.

For a more detailed demonstration of flaws in Austrian capital theory and problems with the alleged “lengthening” of the capital structure, I refer readers to these discussions:
Vienneau, R. L. 2006. “Some Fallacies of Austrian Economics,” September
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=921183

Vienneau, R. L. 2010. “Some Capital-Theoretic Fallacies in Garrison’s Exposition of Austrian Business Cycle Theory,” September 4
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1671886
(4) On loanable funds theory, I appear to get this concession:
“I agree that interest should play less of a role in ABCT than it does in a lot [sc. of] narratives. But, if you read, say, The Pure Theory of Capital, you’ll see that the rate of interest is actually not vital to ABCT, at all.”
Then why does the loanable funds theory appear in so many modern versions of ABCT today like Roger Garrison’s?

And even appeals to Hayek’s later versions of the ABCT where he switched to “false profits” simply beg the question by assuming the truth of this new model. It must face serious problems precisely because of the issue of administered prices.

(5) On the tendency to equilibrium, Catalán says:
“Again, take equilibrium as a reference point. What people mean when they say there’s a tendency towards equilibrium is that entrepreneurs are interested in chasing profits and liquidating unprofitable investments (except under certain conditions).”
It is very difficult to see how this is not a fallacy of equivocation.

No, a tendency towards equilibrium is simply not a state where “entrepreneurs are interested in chasing profits and liquidating unprofitable investments.” This is a bizarrely thin definition of a “tendency towards equilibrium.”

Catalán has changed the definition of “equilibrium” away from what Austrians normally mean by it. The Austrian view of a tendency towards equilibrium would at least stress:
(1) flexible prices moved toward their market clearing levels to equate demand with supply;

(2) a tendency towards the equalisation of profits, and

(3) a tendency toward the equalization of the “originary interest” rate for all commodities.
But I have had this discussion with Catalán before.

In his in previous posts, he implies that he himself does not think there is a real world tendency towards a general equilibrium state (whether Walrasian GE or Misesian “final state of rest”), and at one point implied that Mises was almost a radical subjectivist.

Now it is obvious that a tendency towards market-clearing prices is at least one fundamental element of the Austrian idea of a tendency towards equilibrium and economic coordination, yet this is precisely the element that is grossly unrealistic, given the wealth of data on modern administered prices.
Catalán then says this of my original criticisms:
“these are very weak criticisms of ABCT and they shouldn’t be taken seriously. Some of the ‘criticisms’ raised are actually strong points in the theory, because they’re issues that Austrian capital theorists have dealt with at length before.”
Oh, really?

So there are versions of the ABCT that take account of fixprices? Of the severe problems in thinking that loanable funds theory is accurate in its assumptions about the information communicated about time preference?

Why, then, does the major exposition of the ABCT in recent times by Roger Garrison use a natural rate?

Finally, I get no real discussion of why fixprices would render the “false profits” version of ABCT highly unlikely, given that the alleged price movements causing these “false profits” would be largely non-existent.

Update: Response to Catalán’s Comments

My response to Catalán’s new criticisms in the comments section:
(1) No, I said that the single Wicksellian natural rate, a real rate, it is rate applicable only to a barter world in equilibrium. And I have a hard time seeing how that is not true.

I most emphatically do not deny the importance of good models. What is being asserted above is that these general equilibrium models are effectively irrelevant to the real world as explanations or guides to real world business cycles. This is a different thing from what you are accusing me of.

(2) Once the equilibrium conditions of Hayekian ABCT are lifted and all the other unrealistic assumptions I have discussed in the original post are taken account of, the relevance of ABCT to the real world becomes effectively zero. There is little reason to expect business cycles to be explained by ABCT.

(3) No, the Austrian capital theory literature has not responded to Vienneau.

(4) So Roger Garrison’s Time and Money: The Macroeconomics of Capital Structure (2000), which Austrians (I am fairly sure) regard as one of the fundamental treatments of the ABCT in modern times, has “an interpretation of the theory” that is incorrect? Is Catalán aware of what a stunning concession to me this is? It validates his claim that my original criticisms were “weak” and “shouldn’t be taken seriously” for one.

(5) If Catalán agrees with accepted Austrian views of a tendency to equilibrium, then he has still not proven this tendency. In fact, his statements in (6) clearly recognise the existence of administered prices, and that must mean the real world has a fairly strong impediment to equilibrium in the Austrian sense by failure of adjustment to market-clearing prices in so many markets.

(6) The existence of both flexprice and fixprice markets in the primary commodities sector and others is not in doubt. Perhaps I have not made myself clear: of course, flexprice markets exist.

My comments at the beginning of this post question to what degree these capital markets are flexprice, in the sense of being rapidly flexible in response to demand changes. The graphs do not answer that question. A good many manufactured capital goods, for example, are likely to be fixprice.

Reply to Juan Ramón Rallo on the Austrian Business Cycle Theory

A criticism of my points in the last post is available here:
“Seis malas críticas a la teoría austriaca del ciclo económico,” Juanramonrallo.com, 3 August, 2013.
The author is Juan Ramón Rallo, a PhD in Economics from the University of Valencia and a Masters in Austrian economics from the Universidad Rey Juan Carlos (Madrid). He blogs here.

Some responses:
(1) Juan Ramón Rallo’s first criticism is that the Austrian business cycle theory need not assume the existence of the unreal Wicksellian natural rate of interest. Thus Juan Ramón Rallo seems to agree that the natural rate of interest does not exist.

That is a fascinating concession. Why? It is tacit admission that all versions of the ABCT that do use the Wicksellian natural rate of interest are unsound. Unfortunately, it means that the versions of ABCT by Mises (1934, 2006 [1978]), Hayek, (1931, 1935), Rothbard (2004 [1962], 2009 [1969]), and Garrison (2000) and many others must be wrong, because they all use the natural rate. That is a devastating conclusion.

Indeed, it is the conclusion one must draw from the work of the Austrian Robert P. Murphy on the non-existence of the natural rate and the failure of Austrian attempts to refute Sraffa.

Only versions that dispense with the natural rate would evade such a criticism.

But even Mises’s version of ABCT in Human Action uses the “originary interest rate,” which is effectively the same thing as the Wicksellian natural rate. Certainly, in Mises’s equilibrium world called the “evenly rotating economy” (ERE) this would be the same as the Wicksellian natural rate of interest. Mises asserts that there is “a tendency toward the equalization of this ratio for all commodities,” but this is unconvincing, and just as worthless as any other alleged tendency of the real world to a general equilibrium state. It is hard to see how Mises’s version of ABCT is any better than the other versions that use the Wicksellian natural rate of interest.

Rallo speaks of “maturity mismatches” between savers and borrowers being a sufficient condition for an ABC. But this merely begs the question by assuming time preference and loanable funds.

(2) Juan Ramón Rallo argues that the ABCT need not assume the existence of the full employment of resources. Instead, malinvestment might generate localised bottlenecks and differences in the time preferences of savers and capitalists. But, yet again, as in (1), all this just begs the question by assuming the truth of time preference and loanable funds theory, when these very theories are unsound. See also point (4) below.

(3) The difficulties of classifying capital goods into universal, well defined orders is not irrelevant, despite what the author says. In fact, if these well structured orders are flimsy or non-existent, then whole notion of the capital structure lengthening in response to overexpansion of credit is also highly questionable.

Furthermore, Rallo’s assertion that capital is not plastic or homogenous is a straw man argument. I never asserted this.

These articles by Robert Vienneau provide further discussion of this:
Vienneau, R. L. 2006. “Some Fallacies of Austrian Economics,” September
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=921183

Vienneau, R. L. 2010. “Some Capital-Theoretic Fallacies in Garrison’s Exposition of Austrian Business Cycle Theory,” September 4
http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1671886
(4) I have difficulty understanding criticism (4) at all. Rallo asserts that interest rates do not seek to coordinate new savings decisions with new investment, which appears to be a strange denial of the loanable funds theory that is certainly used in the ABCT.

(5) Rallo says it not necessary to assume any tendency toward equilibrium or the equalization of profit. He then cites Lachmann in support of this and Lachmann’s version of the ABCT.

But Lachmann denied that universality of the ABCT:
“The Trade Cycle cannot be appropriately described by means of one theoretical model. We need a number of models each showing what happens when certain potential causes become operative. The many models that have been constructed by economists in the past are therefore not necessarily incompatible with each other. Overinvestment and underconsumption theories, for instance, are not mutually exclusive. None of them of course is the true theory of the Trade Cycle; each is probably an unduly broad generalization of certain historical facts. Once we admit the dissimilarity of different historical fluctuations we can no longer look for an identical explanation. In dealing with industrial and financial fluctuations eclecticism is the proper attitude to take. There is little reason to believe that the causes of the crisis of 1929 were the same as those of the crisis of 1873.” (Lachmann 1978:100–101).
So is Rallo willing to say, with Lachmann, that the ABCT is not a universal theory, but compatible with other theories (for example, debt deflation theory or a demand side explanation)?

Moreover, I still doubt that Lachmann’s version of the ABCT is better than any other: if anything, Lachmann’s radical subjectivism and rejection of any strong real world tendency to equilibrium makes it even more likely that the ABCT is false.

(6) In his last point, Rallo seems to concede the existence of administered prices. Yet, for some unexplained reason, he still thinks the “false profits” version of ABCT will work. Again, his argument depends on an economy experiencing real shortage of resources and capital. This ignores the empirical reality that, even in most real world booms, capitalist economies still have significant idle resources and are open to international trade.

Finally, Rallo also tries to conflate asset price bubbles with the capital goods distortion postulated by the ABCT. Yet the classic versions of the ABCT do not postulate asset bubbles as the source of discoordination.
