Sorry to be junping into this thread a little late. The highest two graphs
in Figure 5.16 (page 128 of Shaikh and Tonak: Measuring the Wealth of
Nations) for aggregate rates of profit use K as the stock of fixed capital.
Therefore it is not "all of the capital invested in means of production". It
is a rate of return on the stock fixed capital. It is a different measure
from Marx´s rate of profit.
Also, their measure of the value composition of capital is not really Marx's
value composition. Their C*/V* has in the numerator only the flow of
constant capital used up in production, that is, material inputs plus
depreciation. You can check for this on page 95 and then see the
corresponding graph 5.15.
The road of conversion of National Accounts into Marxian Accounts is not
that smooth.
