Paul.
Then the conceptual distinction between the purported differences in
value-generating potentials of simple vs. skilled labour falls through the mesh of
such an empirical-experimental set-up?

(Quantitative) exploitation is a concept dependent upon a concept of labour content
as value-creating. Only then can surplus-value be attributed to surplus-labour. Such
purported quantitative exploitation is to be distinguished from the domination of
productive activity by the capitalist principle of (attempted) augmentation of
monetary value.

This seems to be a misunderstanding. I am not criticizing that certain data relating
to natural conditions of production have to be left out of your statistical
analyses.

What is wrong with using wages to work back to time? In my view: lots. Of course,
one can do it. But what does it say conceptually? An aggregate of hours of labour
then stands in relation to an aggregate of selling prices of commodities. But is
this any different from putting aggregate recursive wages into relation to an
aggregate of selling prices of commodities? I.e. whether labour-power at work over
time is value-creating is irrelevant for these calculations. The test is insensitive
to this difference. What we have are factual monetary quantities put into relation
to each other, nothing more, nothing less. The money is the recognition that
something (a commodity product, or a specific kind of labour-power) is worth
something socially.

The labour theory of value, however, claims that the total labour-power expended in
a certain time has created the value of the total commodity product finally realized
on the market in selling prices. Moreover, according to this theory, the
value-creating potential of the various labour-powers depends on the various levels
of skill (is that measurable in terms of complexity or complicatedness?) and
intensity of that labour-power at work. As far as I can see at the moment, your
empirical analyses do not measure what they purport to measure, viz. the
value-creating potential of human labour-power.

I think that the law of labour value has no bearing on the empirical findings (cf.
above). If the reduction of wages to labour content drops out of the picture, you
are left with the same results, namely, that on the whole, each sectoral capital
succeeds in recouping its advance of money capital, which consists mainly of
(recursive) wage costs. That allows the high correlation between wages costs and
selling prices. Capitals which do not succeed in recouping capital advanced go to
the wall over the short or long run.

Strange that you agree in general. As I see it, value is a concept of sociation
pertinent to a society (capitalist society) which is economically sociated through
market exchange. Under Gosplan, by contrast, the production and distribution of the
country was consciously sociated (whether it worked or not is of no consequence
here) through the plan itself. In particular, labour contents are concretely what
they are and are concretely sociated through the plan in being alloted to various
sectors, places, times, etc. There is no abstract value but only concrete factors of
production which are treated concretely in the overall plan, albeit that they are
reduced for the purposes of planning to concrete magnitudes.

The wonder of capitalism is that the sociation of economic activity works through
such abstract forms of value, with each participant in pursuit of self-interest, a
serious game with a high degree of adaptability (if an enterprise goes broke, change
is enforced). This can only be because the value-form is itself substanceless. Value
is an abstract relational (i.e. social, _pros heteron_) form connecting one member
of society with another. The groundless principle of capitalist economic life is
that money capital must maintain and augment itself through its circuit. Somehow or
other, this groundless and substanceless principle succeeds in motivating the actors
of an economy and also in delivering a material standard of living (with large
standard deviation).
