Do Sectoral Rates of Surplus Value Tend to Equalize, and Why Ask?

It is suggested in an earlier post that the presence of complex labor affects value creation in Marx’s theory, including at the aggregate level. The argument starts from Marx’s distinction between concrete and abstract labor. In making this distinction, Marx explicitly identifies productivity as a property of concrete labor and labor complexity as a property of abstract labor. Variations in productivity, since they relate to concrete labor, directly affect the aggregate production of use-values (‘real’ output) but not the aggregate creation of value (socially necessary labor time or nominal value). In contrast, variations in labor complexity, since they relate to abstract labor (the substance of value for Marx), directly affect the aggregate creation of value rather than the aggregate production of use values.
