Note that the definition of value in vol 1 is done in abstraction from changes in technology over time. In vol 1 a change in technology changes values, but there is not systematic treatment of the effect of a continuous rate of change of technology on the definition of commodity values. It strikes me as illegitimate to try and reconcile prices of production computed on a temporal basis with value defined on a non temporal basis. Once you deal with continuous rates of change of labour productivity then you are stepping outside the theoretical space on which the original theory of value was based. Samuelson attempted do deal with this problem of continuous change in labour productivity and its implication for labour values in his paper 'A new labour theory of value for rational planning through the use of the bourgeois profit rate' Paul Cockshott firstname.lastname@example.org > Rakesh wrote > This is not true.
