Is it possible, though, to speak about the composition of capital in
an individual branch of production (as Marx did)?  If  there is a
composition of capital in individual branches of production and in
the macroeconomy (and different compositions of capital in different
macroeconomies), why aren't there also rates of surplus value in
individual branches of production as well as an average rate in
the macroeconomy?

c, v, and s are all linked to the money-form so that can't be the reason.
Since v is in the denominator of both rates,  it follows that if one
wants to make a claim about the rate of surplus value being only
a macroeconomic rate, there must be something about s -- and _not_
v -- which requires that it can only be constituted at the macroeconomic
level.  Yet,  what about _value_ production  rather than _just_ surplus-
value production?  To be consistent, it seems to me that either c/v
and s/v are macroeconomic rates only or they are rates
that apply at both the level of individual branches of production and the

Can anyone on the list explain the 'macroeconomic only' interpretation(s)
more fully?
