Well by putting them there, everything works out, there is no transformation problem, and Marx's value theory does not have to be discarded. The only people who are going to think there is still a transformation problem are those who like the kinds of mathematical problems general equilibrium exercises generate--counting equations and unknowns which seems to make Sraffa so pleasingly familiar to some of you. If I am going to do math, it will be things like Thom's catastrope theory or Goodwin's Lotka-Volterra equations. > > Marx's main concern is not price determination.

The only way for Marx to solve that "major >problem" (as he saw it -- as you know Paul and I think it's not >so major after all) is to show the precise theoretical >relationship between the system of values and the system of >prices of production. Hand-waving won't do: that's just what >Marx claims is inadequate about Ricardo's own treatment of the >point. No Marx's major problem is --I will say for the millionth time-- to show that that not only does the principle of the average rate or profit not contradict or modify the law of value, it can only be explained on the basis thereof. He is not aiming at a price theory; he makes no effort to break his prices of production down into unit prices; he makes no effort to account for various factors which would allow him to descend to the world of unit prices (deductions from SV, turnover, monopoly). Why? Because he is taking up the debate between Ricardo and Malthus on the contradiction between the average rate of profit and the law of value. It is this contradiction that has to be resolved, and in resolving it, Marx shows that the law of value cannot account directly for the phenomena of bourgeois society, i.e., the explanadum for value theory is no longer relative prices. > >> "Dynamic stuff is off the agenda for the moment. >> When we get past the main transformation argument we get a whiff >> of dynamics: "In spite of the great changes occurring >> continually, as we shall see, in the actual rates of profit >> within the individual spheres of production..."

Moscow ed., p. 166. Fine. But my point still stands. Marx is not saying here that prices of production are not changing; he is saying that why they change in the first instance is due to change in the underlying values of commodities, not changes in the average rate of profit. You simply misrepresented these passages. Marx shows no indication in this chapter that his analysis is so static that prices of production cannnot and are expected not to change; time subscripts are indeed implicit as he is trying to account for the various reasons prices of production are changing. Your response is fully non-responsive. > > >> "In the given theoretical context, then, a difference between >> input and output prices for a given commodity can only be a >> symptom of an incomplete analysis." >> >> 1."Then"?? did I miss the proof, argument here? > >In using the term "incomplete" I'm assuming a background >knowledge of the idea that Marx's tableau represents the first >step of an iterative solution (Morishima, Shaikh and others). Doesn't speak to my point. Many have argued that it was illogical for the inputs in the second tableau to be in "values". I have argued that it would have been illogical to have transformed them in terms of a category that is not derived until the completion of the second tableau. Now all the confusion begins with a simple, yet devastating, slippage: Marx admits that the inputs have to be transformed into prices of production. He does not say that they have to be transformed into the SAME prices of production as the outputs. An iterative or a recursive or simultaneous solution aims, if I follow you, to do the latter, i.e., not only to remove time subscripts from the analysis but to make fantastic appeals to backward causation. At least admit that these are two different things, and that hitherto the entire literature has simply conflated them (or denied that Marx is admitting a need to transform the inputs). > >> 2.

Yes, I noted this in my reply to him, which I must have sent to his private address. Strictly speaking, cost price is the money sum laid out for the inputs--Fred is right. But that money sum is determined initially on the assumption that means of prod and wage goods (indirectly) are purchased by the capitalist at value. > >> 3.

And so on. Again this is non responsive. I suggested to you why such a procedure, which is nothing but the fallacy of backward causation, is absurd. And there is no reason to discard Marx's value theory if he does not want to make this ridiculous assumption. The only leg you have to stand on then is to say then that while Marx recognizes the need to transform the inputs, he has no way of doing it. And I counter for the umpteenth time we would only have to know the cost prices derived from transformed inputs if we were after the quantitatively correct prices of production for the outputs, but we don't need to know the exact modified cost prices to understand in logical and abstract terms how Marx resolves the debate between Ricardo and Malthus by showing that the more capital develops, the more the average rate of profit itself becomes the form in which the law of value asserts itself. Marx's value theory does not collapse if we make the only reasonable assumption--that the modified cost prices would have been derived from different prices than the prices of production for the outputs. That is the *only* assumption one has to make for Marx's Capital 3, ch 9 resolution of said contradiction to "go through", as Ajit puts it. I also suggest that if such a simple assumption saves the entire theory, it is only perverse behavior welded to the interests of the powerful that disallow such a simple "saving" assumption from being made. > >> It simply does not matter.... > >That's what Marx said, off-handedly. We know now he was wrong. >The properties of the fully-transformed system are subtly >different from those Marx asserted on the basis of a first-round >transformation. Yes, yes. Only if you continue to make the slippage that by saying that inputs would have to be transformed into prices of production, Marx is also saying that there should be an equilibrium price solution such that the prices of production for the inputs are the same as the prices of production for the outputs. But as I have already noted, Marx shows himself actively disinterested in such a thing in this very chapter where he is already analyzing why prices of production change. > Have you looked at, say, Sweezy's exposition of >Bortkiewicz? (A clear, relatively non-technical treatment.) Yes. And wrong. The other mischief was in promulgating Bauer and Hilferding over Grossman. I am much more indebted to the other great American intro to Marx--Wm J Blake Marxian Economic Theory and Its Criticism, 1939. Married to the novelist Christina Stead, Blake would later visit Grossmann in Leipzig in 1949. Both Geoffrey Pilling and Geoffrey Kay have expressed similar admiration for Blake's synthesis. It's about 700 pages. At one point, I could pretty much tell you the main point of any paragraph once a few lines of it were delivered. But now I am old and stupid. Unlike most Marxists, I was not introduced to Marx by Meek, Dobb and Sweezy but Grossmann and Korsch and their students Blake and Mattick. Bernice Shoul seems to have been another American student of Grossmann's, so I look forward to reading her 1947 Radcliffe dissertation. >Whether this "matters" in a larger theoretical sense depends on >how seriously you take the equalized-profit benchmark.

All commentators don't seem to realize that Marx could not have had his inputs sell to capitalists at prices of production until the very category is derived at the completion of this so called hybrid tableau. A dehybridized model at this point (the second tableau) would have been an logical error in terms of introducing concepts without having rigorously derived them. Again that the profit rate was equalized in the previous period does not logically entail that the inputs were bought at the same prices of production as the outputs. It only means that the inputs would have been transformed, not transformed into the identical prices of production of this period. Again there is simply a logical slippage here. I see no reason why we need the same prices of production on both sides or why it would be reasonable to study the properties of such a replicating system as a model of anything. All the best, Rakesh
