I think Jim you have conceded the point. In order to establish the theory of relative surplus value he assumes that prices are proportional to average labour time. The whole analysis of the super profit of the innovator rests on this, and the secondary general effect on the rate of surplus value by reducing the price of wage goods depends on it as well.
But the assumption you make "Under this assumption, if labor productivity rises (on average), the average commodity's value falls and so does that of the workers' consumption commodities." is not strong enough, you can not deduce that wage goods prices will fall if average labour productivity rises. It would be possible for average labour productivity to rise and average prices to fall but it might be the case that the price of wage goods remained the same whilst luxury goods prices fell. For Marx's argument to work the values and prices of commodities have to be strongly correlated. ________________________________________ From: [email protected] [[email protected]] On Behalf Of Jim Devine [[email protected]] Sent: Sunday, July 17, 2011 10:20 PM To: Progressive Economics Subject: Re: [Pen-l] Law of Value (was Re: interesting) Paul Cockshott wrote: >> If it is not a theory of price determination what is it? me: > I see [Marx's] value theory as a macro-theory (so the so-called > "transformation problem" is much the same as the familiar aggregation > problem).

This is inherently an inter sectoral process.< right. But in the main narrative of volume I of CAPITAL (after chapter 3), Marx abstracts from the technical differences among different sectors (and what use-values are produced), focusing instead on the class relationship between "capital in general" and "labor in general." This means that value = price on the micro-level (as inter-sectoral differences in the composition of capital are abstracted from), even though this equality is true only on the macro-level and for an average industry (with the average composition of capital).[*] Under this assumption, if labor productivity rises (on average), the average commodity's value falls and so does that of the workers' consumption commodities. [*] He also assumes that value = price in volume II. On the first page of volume II: "In order to conceive these forms in their pure state, one must first of all discard all factors which have nothing to do with the changing or building of forms as such. It is therefore taken for granted here ... that the commodities are sold at their values... Likewise disregarded therefore are any changes of value which might occur during the movement in circuits." -- Jim Devine / "Segui il tuo corso, e lascia dir le genti."
