But, did this crisis that
industrial capital faced then mean that there was no way out for it, and that the
mass of
profit must fall, as Smith and Hodgskin believed? Would it mean that, even if it escaped this immediate crisis, it would only lead to a bigger crisis and more rapid series of crises, leading to its collapse, as many modern catastrophists have argued? No, Marx explains.
Ricardo noted that when
wages rise so that it is no longer cheaper to use women to pull canal barges, industrial capital turns to the use of horses, which are, in fact, more efficient, especially when barges become bigger and heavier, as more freight is moved around. Industrial capital does not engage in major technological revolutions, which involve it in greater immediate expense, unless it becomes worthwhile to do so. But, this introduction of technology/machines shows again why the idea of a relatively fixed labour supply, leading to falling profits, whilst valid in the medium term, is false in the long-term. If labour
productivity rises, less
labour is required, or put another way, its as though one worker is now equivalent to 2, 3 or more workers. In
Capital I, Marx explains the way this higher productivity results in the creation of
relative surplus value in two ways.
Firstly, if one producer introduces some new machine that raises the productivity of the labour they employ, it has this effect of making their labour like
complex labour. In other words, it is as though the new
value they create in an hour is equivalent to 2,3 or more hours labour of workers employed by other producers of that
commodity. That is so because they produce 2,3, or more times the
quantity of those commodities, all of which sell at
the market value. Its the same as where a farmer has the benefit of more fertile land.
But, this particular advantage disappears when other producers of the commodity introduce the same machine – just as when the use of drainage and irrigation etc., raises the fertility of all land. Now, all of that labour reverts back so that it all produces an hour of new value in each hour worked. However, far more commodities are now produced in that hour so that
the unit value of each commodity falls. This, in fact, is central to Marx's explanation of the real basis of
the long-term tendency for the rate of profit to fall.
In other words, the value of a commodity is comprised of the value of the
constant capital (materials and
wear and tear of fixed capital) consumed in its production, plus the new value created by labour in its production. The latter resolves into
variable capital (the value of the commodities required to reproduce
labour-power) and
surplus-value/profit. So, if this new value falls, as a proportion of the value of each commodity unit, as a result of the rise in productivity, but the value of constant capital (c) remains the same, then the value of constant capital rises relative to the new value created (v + s). Unless s rises relative to v (a higher
rate of surplus value), s falls relative to c, and to c + v, i.e.
the rate of profit falls, even if the total mass of profit rises.
But, in
Theories of Surplus Value, Chapter 23, Marx points out, again, that this effect is, also, grossly overstated. Firstly, he points out that where there is a generalised technological revolution, the rise in productivity
reduces the value of all those commodities that comprise the constant capital.
If “one worker produces a spinning-machine whereas previously he produced only a spindle, then the ratio of value remains the same...”
A spinning machine, spins much more yarn than a spinning wheel, so the value of the machine is
much less per unit of output. What increases is the
amount of material spun, in terms of its
physical quantity/use value, but, as he noted, it is not these physical quantities that ultimately count, but the relationship of their respective values.
“For us, however, the main thing is: does this fact explain the decline in the rate of profit? (A decline, incidentally, which is far smaller than it is said to be.) Here it is not simply a question of the quantitative ratio but of the value ratio.”
The technical composition of capital is what lies, objectively, behind the rise in
the organic composition required to drive the long-run tendency for the rate of profit to fall, i.e. rising productivity means that the
physical quantity of material processed rises relative to both the labour required to process it, and the
fixed capital which brings about the higher productivity. But, that ignores the role of that rise in productivity in relation to the value of that material itself.
“The cheapening of raw materials, and of auxiliary materials; etc., checks but does not cancel the growth in the value of this part of capital. It checks it to the degree that it brings about a fall in profit.”
