Marx’s
Capital Volume 1, Part 5a
The Rate of Surplus
Value
Karl Marx’s
“Capital” is not a hasty book. It proceeds at a measured pace, with a degree of
repetition. Some parts appear difficult, only to yield up their secrets at a
second reading with ease.
The chapter
on the Rate of Surplus Value (download linked below) is a good example of all
this. At first reading it appears dense. It appears to contain new things
unconnected to what has gone before, or to what comes afterwards. Yet nothing
could be further from the truth: In this chapter are re-stated some of the
simplest, basic relationships, derived from the earlier chapters, and
explicitly anticipating Volume 3 of the great work.
Let us pick
out some of the easier passages. Marx begins with a “tautology” – a truism, or
statement of the obvious, but one that has to do with “the expansion of
capital”, the secret of which is the key to the entire work. Marx writes:
“Since the value of the constituent elements of
the product is equal to the value of the advanced capital, it is mere tautology
to say, that the excess of the value of the product over the value of its
constituent elements, is equal to the expansion of the capital advanced or to
the surplus-value produced. Nevertheless, we must examine this tautology a
little more closely.”
Soon he
puts down an important working definition, “constant capital”. Important
because similar formulations, but with different meanings, are used in
bourgeois accounting. Marx says:
“Throughout this Book therefore, by constant
capital advanced for the production of value, we always mean, unless the
context is repugnant thereto, the value of the means of production actually
consumed in the process, and that value alone.”
“Constant”
is the companion of “variable” capital, which is the capital advanced for
labour. Says Marx:
“From what has gone before, we know that
surplus-value is purely the result of a variation in the value of v, of that
portion of the capital which is transformed into labour-power; consequently, v
+ s = v + v, or v plus an increment of v. But the fact that it is v alone that
varies, and the conditions of that variation, are obscured by the circumstance
that in consequence of the increase in the variable component of the capital,
there is also an increase in the sum total of the advanced capital.”
Returning
to constant capital, Marx says that for the sake of particular calculations, it
may be taken out of the equation. Marx did not live to see something called
Value Added Tax (VAT) but if he had, he would have recognised the same move. In
the calculation of VAT, that portion of money advanced that does not increase,
is removed out of the calculation. Marx put it thus:
“At first sight it appears a strange
proceeding, to equate the constant capital to zero. Yet it is what we do every
day. If, for example, we wish to calculate the amount of England's profits from
the cotton industry, we first of all deduct the sums paid for cotton to the
United States, India, Egypt and other countries; in other words, the value of
the capital that merely re-appears in the value of the product, is put = 0.”
Then at
once Marx reminds us of the importance of the constant and apparently inert
part of the capital. This is where he refers to “the third book” (Volume 3),
which was not actually published until after he died, and which deals among
other things with the “tendency of the rate of profit to fall”, the discovery
of which depends upon these simple preliminaries:
“Of course the ratio of surplus-value not only
to that portion of the capital from which it immediately springs, and whose
change of value it represents, but also to the sum total of the capital
advanced is economically of very great importance. We shall, therefore, in the
third book, treat of this ratio exhaustively. In order to enable one portion of
a capital to expand its value by being converted into labour-power, it is
necessary that another portion be converted into means of production.”
There are
more definitions in this chapter. Here is what Marx means by “necessary”
labour-time, and incidentally, the reason why capitalists pay their labourers:
“That portion of the working-day, then, during
which this reproduction takes place, I call "necessary" labour-time,
and the labour expended during that time I call "necessary" labour
[5] Necessary, as regards the labourer, because independent of the particular
social form of his labour; necessary, as regards capital, and the world of
capitalists, because on the continued
existence of the labourer depends their existence also.”
Here we
return to the key of the book: Surplus Value, the secret of the self-increase
of capital, which Marx says “has all the charms of a creation out of nothing”.
It’s what the capitalist loves and constantly seeks:
“During the second period of the
labour-process, that in which his labour is no longer necessary labour, the
workman, it is true, labours, expends labour-power; but his labour, being no
longer necessary labour, he creates no value for himself. He creates
surplus-value which, for the capitalist, has all the charms of a creation out
of nothing. This portion of the working-day, I name surplus labour-time, and to
the labour expended during that time, I give the name of surplus-labour.”
Marx gives
a simple procedure:
“The method of calculating the rate of
surplus-value is therefore, shortly, as follows. We take the total value of the
product and put the constant capital which merely re-appears in it, equal to
zero. What remains, is the only value that has, in the process of producing the
commodity, been actually created. If the amount of surplus-value be given, we
have only to deduct it from this remainder, to find the variable capital. And
vice versa, if the latter be given, and we require to find the surplus-value.
If both be given, we have only to perform the concluding operation, viz., to
calculate s/v, the ratio of the surplus-value to the v variable capital.”
The second
part of this chapter consists of examples. If time is short, it can safely be
skipped. The third part, containing Nassau W. Senior’s theory of the “last
hour” is easier.
This
gentleman Mr Senior also appears in “Theories of Surplus Value”, sometimes
called “Capital Volume 4”, which is Marx’s distilled notes from his exhaustive
study of all the preceding writers about political economy, the study that
allowed him to arrive at a confident position of scholarly authority.
The
arguments that Senior proposes are very far-fetched, yet one would not be
surprised to hear such things from employers of today, and we still rely on
Marx to refute them.
The last
section is a transitional paragraph leading into the next great chapter, almost
a book by itself: “The Working Day”.
Illustration: The Peterloo Massacre, Manchester, England,
1819. A crowd of 60,000-80,000 gathered for a protest rally against
unemployment and poverty. They were then charged by soldiers on horseback
(cavalry) and cut down with sabres, killing 15 and injuring up to 700.
