Episode 26: Dialogue with Patrick Murray on the Value-Form Paradigm, Part 2

Brendan and Andrew continue their dialogue with Patrick Murray, the noted value-form theorist. (The value-form paradigm is a Marx-inspired strand of political economy that focuses on the market.) Patrick responds to Andrew’s arguments that Marx’s views on the origin of profit, intra-firm trade, and the quantity theory of money presuppose that commodities’ prices are determined before they are sold. And, as in Part 1, much of the discussion focuses on whether, in Marx’s theory, a commodity’s value is only potential before it is sold; whether “co-constitutive” value-form theory collapses into a more extreme version; and whether Marx held that the magnitude of a commodity’s value is determined exclusively by the amount of labor that is socially necessary to produce it.

Throughout the discussion, frequent reference is made to: a published symposium on the value-form paradigm, in which Andrew and others criticized the paradigm, while Patrick responded to them; Part 1 and Part 2 of the recent RFH discussion of “The Value-Form Paradigm vs. Marx’s ‘Capital’”; and Marx’s Capital, especially chapter 1 and chapter 3 of volume 1.

  1. Is the total value labor can create by producing a single product over a fixed period of time, say linen, determined by demand, according to Marx? If there’s an amount of labor of average intensity, using average production methods, that would create enough linen to satisfy demand, does labor above that amount create value? If not, does Marx think there is any limit to the value that labor can produce, over a fixed period of time, by making a single product other than the maximum amount of labor and means of production available?

  2. Hi Seth,

    “Is the total value labor can create by producing a single product over a fixed period of time, say linen, determined by demand, according to Marx?”

    In Marx’s theory, demand determines how much of the linen has use-value. Any linen that doesn’t have use-value isn’t a commodity and thus doesn’t have value. The magnitude of the value of the pieces of linen that are commodities, and thus have value, is determined exclusively by the avg. amount of labor currently needed to produce them–not by demand.

    This is the case even if all of the linen can be sold at a price less than the value (per unit) of the portion of the linen that does have value. E.g., imagine that 1200 hrs of labor are expended on 200 yds of linen, but that demand for linen is only 120 yds. Only 120 yds are use-values and have values. The amount of labor needed to produce them is (120/200)*1200 hrs = 720 hrs. The other 480 hrs. of labor don’t create value. The avg. amount of labor needed to produce the 120 yds that are actually commodities is 720 hrs/120 yds = 6 hrs per yd. If the 120 yds sell at their value, they sell for the monetary equivalent of 6 x 120 = 720 hrs of labor. But it’s probably possible to sell all 200 yds of the linen, at a price that’s the monetary equivalent of 720 hrs/200 yds = 3.6 hrs per yd.

    Demand isn’t determining, or affecting in any way, the value of those yards of linen that are commodities, even though it may seem to do so. Their value is exclusively determined by the average amount of labor needed to produce them. Nor is the total price of the linen affected by demand (in this example)–the total price = the total value. The whole mass of linen has a total value = to the monetary equivalent of 720 hrs., and that is also its total price!

    I think the above answers your other questions, too, though I’m not sure I’m catching your meaning.

    You may wish to check out the comments in the Ep. 25 page, where we’re having a similar discussion.

    • So use value not only refers to the quality of a thing, as usable to fulfill some desire, but to a quantity of things. Given a quantity of things, some of that quantity may have use-value, and therefore may have value and be commodities, whereas another of that quantity may have no use-value and therefore no value.

      I’m trying to get my head around the disagreement. There was a lot of assertion of being in agreement.

      Patrick seems to account for fluctuations in price due to demand as commodities as being “less” socially necessary and therefore having less value. He interprets Marx’s concept of socially necessary as referring to demand as well as production methods. So as demand decreases he asserts that the entire mass of things are still commodities, but have less value.

      Andrew, you are interpreting Marx as saying that demand fluctuations make a certain number of things that were commodities no longer commodities. Demand does not affect the value of individual commodities, but affects the total value. If demand decreases, this total value can express itself as a reduced price on a mass of things that are more numerous than demand, or some of that mass of things may be destroyed so that only the commodities remain.

      It seems the total value of commodities and their appearance as prices of individual commodities are being conflated on Patrick’s part. It’s possible only a quantity of things may possess use-value and be commodities. This is the case before the commodity owner takes the goods to market, the market is merely the place where this fact appears. They may try to compensate by burying any extra in a ditch, or lowering the prices of each unit. This is the being of value as it presents itself in the market, but in no way affects the value of each individual commodity.

  3. Andrew, you are interpreting Marx as saying that demand fluctuations make a certain number of things that were commodities no longer commodities. Demand does not affect the value of individual commodities, but affects the total value. If demand decreases, this total value can express itself as a reduced price on a mass of things that are more numerous than demand, or some of that mass of things may be destroyed so that only the commodities remain.

    Basically, yes, although I think the expression “Demand … affects the total value” is misleading and vague. So it’s an expression I avoid.

    The total value of a mass of commodities is, by definition,

    total value = (value per use-value) x (# of use-values)

    In Marx’s theory, the “value per use-value” is determined exclusively by the avg. amount of labor that’s socially necessary to produce this kind of use-value–given current technology, and average skill and intensity.

    This doesn’t mean that demand can’t affect the “value per use-value,” as I discussed either in Ep. 25 or Ep. 26. If demand is especially high, for example, inefficient producers will be able to produce profitably, and do so. Their entry will reduce avg. efficiency, and thus raise the avg. amount of labor that’s socially necessary to produce this kind of use-value, and thus raise the “value per use-value.”

    The “# of use-values” depends on demand (because an item for which there is no demand isn’t a use-value).

    So in this theory, there are two channels by which demand can be said to “affect” the total value. But again, I avoid expressions like that, because they misleadingly seem to suggest that the magnitude of a commodity’s value, according to Marx’s theory, is not determined exclusively by the avg. amount of labor needed to produce it. That misleading suggestion is just plain false.

     
    “I’m trying to get my head around the disagreement. There was a lot of assertion of being in agreement.”

    Yeah, it can be confusing, because what you listened to is what I call a “kreplach moment” :

    http://fetchmemyaxe.blogspot.com/2006/06/and-now-kreplach-joke.html

    –in fact, more than one kreplach moment.

    Patrick kept trying to argue that demand is a “determinant of value” in Marx’s theory, and “therefore” that Marx either (a) contradicted his own theory or (b) smuggled in sneaky caveats that he didn’t disclose to readers, when he wrote that the magnitude of a commodity’s value is determined exclusively by the avg. amount of labor needed to produce it. Just as in the kreplach joke, Patrick agreed with every step of my demonstration that his points and textual evidence did not contradict or require modification of Marx’s “determined exclusively” thesis. But then, when it was all put together, and the conclusion was that Marx’s “determined exclusively” thesis emerges unscathed, it was KREPLACH!!!! Patrick balked. He evaded the “determined exclusively” conclusion, did not accept it, and instead reverted to his vague and ambiguous statement that demand is a “determinant of value.” This happened more than once.
