Cockshott:
This depends upon the assumption that K is constant. Why should
we assume this. The historical periods in Britain in which the
organic compostion has risen have sometimes, though not always,
been associated with rising total capital stock.

During the 1950-1970 period capital stock and organic composition
both rose and the profit rate fell. In the period 79-89 the organic
composition rose whilst the capital stock remained stagnant or declining.
In this latter period, your restriction of Franks theorem appears to hold
good, the
rate of surplus value rose, and for lower paid workers the real
wage fell. The consequence was that the rate of profit rose.

In the prior period as well, Franks theorem seems to apply, but
now in its full form - allowing K to rise.

Cockshott:
You have to take into account however, that what matters is whether a theory
accords with reality. Franks theorem accords with what I observe to have
occured in the historical record.
