So let us be purely mathematical and impose the following possibility: sī variable v constant C variable through variations in c You are right to mention the working day, intensity of labor and wages. Yet we do not need to maintain them constant. In fact, since v is constant sī can vary only if the length of the working day, the intensity of labor or the wages vary. But once we allow for anyone of these factors determining the rate of surplus value to vary we have the subcase stated above whose formula is: l1 = (mī1/mī)(C/C1)l, that is, the rate of profit modified will depend on the ratio between the modified and the previous rate of surplus value and on the ratio between C and C1. This formula did not appear before! Should it not be considered as an independent case? <<< Hi again Paolo. You raise different issues: I.) you ask: why didn't Marx consider the case of v constant and s and C variable in Vol. 3, Ch. 3? The above question is, of course, related to another question you ask: _should_ he have considered that as an independent case in Vol. 3, Ch. 3? I consider it highly unlikely that the overlooked the case you mention "by mistake". There are other possibilities: to begin with, note the footnote at the end of this chapter by Engels in which he points out that the "manuscript also contains further and very detailed calculations.... I have refrained from reproducing this material, since it is of little importance for the immediate aim of this book....(Penguin ed., p. 162). So one line of inquiry might involve a re-look at the original drafts to determine _what exactly_ was not included for publication from this chapter. I think, though, that one should also ask whether he didn't discuss the sub-case you mention because he felt that he had already discussed that subject elsewhere. He seems to say as much early on in Ch. 3: "The same applies to the remaining three factors: *length of working day, intensity of labour, and wages.* Their influence on the mass and rate of surplus-value was developed in detail in Volume 1 [Chapter 17]...." (Ibid, p. 143). There is also an indication that at least one of these possibilities would be explored more concretely in a separate book to be written _after Capital_: thus, in Vol. 3, Ch. 14, Section 3 he indicated that a "reduction of wages below their value ... "has its place in an account of competition, which is not dealt with in this work" (Ibid, p. 342). II.) You ask me to respond to the formula that you propose above. Before I do that, I would like to see that formula developed more and, in particular, made symbolically more consistent with the other formulas in that chapter. [btw, I assume that the beginning of that formula was a typo and that where you wrote '1' (upper-case) you intended to write "p'".] In solidarity, Jerry
