Date: Thu, 23 Nov 1995 12:28:08 -0800 From: James Miller <jamiller-AT-igc.apc.org> Subject: avoirdupois THE TECHNICAL COMPOSITION OF CAPITAL For a long time John insisted that Juan and I answer the question: "does the technical composition of capital increase at a faster or slower rate than productivity?" At the same time, John declined to explain how the TCC could be measured, i.e. what units could be used to calculate the quantity of the means of production. Juan and I explained that meaningful quantitative measurements of the whole of the means of production, as use values, were not possible, or were very difficult, due to the variety of raw materials, auxiliary materials, machinery, tools, power supplies, etc. Then, remarkably, in a post on Nov. 15, John comes up with an unexpected concession to the point that Juan and I had been making. He responded to Juan's example of replacing ordinary hammers with electrical hammers, saying, "assuming that an electric hammer has the same mass as the 'ordinary hammer' and, thus, hammers seem to more than triple as even more inputs are added, it would seem that this part of constant capital is more than doubling, which means it is growing faster than output which is doubling." Here John is comparing the old hammer with the new hammer in units of mass, which can be expressed as pounds or kilograms. As John pointed out (in his post of Nov. 15), Marx "defined the term [technical composition of capital] as the mass of the means of production per worker." This is right. _Capital_, Vol. I, Chap. 25. But the question might be raised: what did Marx mean by "mass"? Marx didn't define "mass" any further. As far as I know, he didn't say the term should be used the same way as in physics. Yet, I don't think it would be too far off to use it this way. It could be argued that the complexity, diversity and organization of the means of production is part of the technical compo- sition of capital, and, for some purposes, this is undoubtedly correct. Yet, aside from that, Marx did say that the mass of the means of production per worker would grow as capitalism develops. And I think one can measure this mass as a physical mass, in kilograms and tons. And if it is measured in this way, one can see that this mass grows in relation to living labor. At the same time, however, it must be kept in mind that the effectiveness, or productivity, of the machinery, tools, containers, conduits, etc. is related to design and function, not just to mass. Productivity is related to both mass and function of the productive apparatus. With regard to measuring the technical composition of capital, it is interesting that, although John (and Juan and I, as well) referred to "mass," no one before now suggested measuring TCC as tons per worker. But I'll just proceed on the assumption that this way of measuring the TCC can be used until a better suggestion comes along. TCC AND PRODUCTIVITY Now, what John wants to know is whether productivity (material output per worker) increases faster or slower than TCC (tons of means of production per worker). For the purposes of answering this question we must divide the means of production into two categories: raw materials and the material elements of fixed capital. (For the purposes of this argument auxiliary materials can be subsumed under fixed capital, since they do not bodily enter into the product.) Regarding raw materials: the greater productivity of labor is synonymous with the faster processing of raw materials. Except for losses due to unavoidable waste, errors, etc., what comes in as raw material goes out as finished product, so with regard to the faster processing of raw materials, the change in the TCC is the same as the change in the productivity rate. In other words, if you start with a machine that makes one ton of cotton into one ton of yarn per day, then later you install a machine that converts five tons of cotton into five tons of yarn per day, the gain in input is the same as the gain in output, in terms of pounds of material per worker. So the TCC increases at the same rate as productivity, as far as the raw material is concerned. But it is different with the material elements of fixed capital. Productivity gains increase the ratio of fixed capital per worker. The fixed capital per worker accumulates from one generation to the next as each worker operates a larger bulk, or mass, of productive equipment. Of course, the increase in productivity is not a function of the bulk of the machinery, but its design and function. Nonetheless the technological innovations have the effect of increasing the mass of machinery per worker. In this respect, it may be relevant to recall what Marx said about the growth of the means of production in relation to productivity: "but those means of production play a double role. The increase of some is a consequence, that of the others is a condition, of the increasing productivity of labor." (_Cap._ Vol. I, Chap. 25, 2nd page of Sec. 2) Thus, on the basis of the foregoing, I would say that the tendency is for the TCC to increase more, or "faster" than the productivity of labor. I say this because, while the tons of raw materials processed per worker increases both the TCC and the productivity of labor at the same rate, you have to add to that the growth in the material elements of fixed capital, which registers the growth of the TCC (tons per worker). In other words, for every increase in material units of output per worker, you have an equal increase in material units of input per worker (raw materials), plus an increment added to the material fixed capital as well. Thus I have finally answered the question John asked. I say the TCC increases faster than the productivity of labor. Now John has come to a different conclusion on the basis of his reading of Marx. He has referred to pp. 108-109 of _Cap._ Vol. III, and pp. 383-385 in _Grundrisse_. On the basis of what he believes Marx said in these passages (and perhaps elsewhere as well), John concludes, "for Marx, if we view the accumulation process in material terms, the inputs do not grow as fast as outputs for a given labor force." (Post of Nov. 15) I think he is mistaken. Let's take a look at the example cited from _Grundrisse_. Here Marx discusses the transition from a hand printing press to a self-acting press. The gains in faster processing of raw materials and increments added to the fixed capital are compared to living labor, here measured as a period of four days. The raw materials increase from 30 per four working days to 100 per four working days. (The figures of "30" and "100" here refer to values, but they can also serve as indices of the quantities of raw material, as long as it is assumed that no price changes take place, i.e. that the "30" and "100" could just as well refer to pounds of material as well as to their value.) Regarding the material elements of fixed capital, the presses, here Marx does not indicate their weight, but states that the hand press has a value of 30, and the self-acting press a value of 60. If we assume that the self-acting press weighs more than the hand model, then the TCC (pounds of means of production per worker, both in raw materials and in added weight of machinery) has increased more than productivity (output in pounds per worker). Of course, it is possible that the self-acting press weighs less than the hand-operated machine. In this case, the productivity of labor would increase more than the means of production. And, as I said, Marx had nothing to say about the weight of the presses. But I think if you examine the history of the printing industry, you will see that, in general, the mass of the printing machinery per worker does increase. And the same is generally true in other industries as well. Juan's recent post against John once again returned to the confusion of value with material that is evident in the Ricardian tradition. Juan correctly points to this as the source of John's confusion. I agree with Juan, but my approach here is to try to find a way to narrow down the discussion to terms which can be more easily handled. Only when we gain some common approach to measuring the TCC can we profitably discuss the relation of TCC to the productivity of labor, and the implications of this for the tendency of the rate of profit to fall. This is particularly necessary since John has indicated that he believes that the TCC can be measured as "tons per worker" (see first quote from John, above), but he has never explicitly stated it in so many words. If we can reach agreement on this, then we can proceed forward in the discussion. ENGELS On Nov. 23 Hinrich Kuhls posted a response to John regarding Engels's comment in _Cap._, Vol. III, Sec. 4. John had posted an argument on pen-l saying, "...Marx teaches that fixed capital does not grow as fast as productivity and Engels follows with a few paragraphs that state the opposite." John is mistaken here, as far as I can tell. But what makes it difficult to argue with John is that he has a tendency (and it's evident in this case) to make an assertion regarding what Marx supposedly said without attempting to quote, summarize or paraphrase Marx. We are left in the dark as to why John thinks that Marx believed that "fixed capital does not grow as fast as productivity." John gives us his conclusion, but gives no clue as to how he derived it. I'm still hoping that I can influence John to be more specific in his references to Marx. If he can make some progress in this area, then we can have a more satisfactory exchange of views.
