Part Four: The Production of Relative Surplus-Value

Chapter 12 – The Concept of Relative Surplus-Value

This chapter introduces the concept of relative SV.

SV can be increased not only by lengthening the working day, but equally, with a given length of working day, by reducing the length of the period of necessary labour.

(Although in practice this is often done by paying labour-power below its value, Marx is assuming that all commodities exchange at their value for now, so this possibility must be left aside).

The necessary labour-time can only be reduced by reducing the value of labour-power, i.e. the amount of labour-time required to produce the worker’s means of subsistence.

This is turn depends on an increase in the productivity of labour.

Capital can no longer take the mode of production as given.

(Note: a fall in the value of labour-power does not mean a fall in the real wage, but rather a reduction in the time required to produce the means of subsistence)

This leads Marx to distinguish absolute SV “which is produced by the lengthening of the working day” from relative SV “which arises from the curtailment of the necessary labour-time” (p. 432)

Relative SV cannot be produced directly by a single capitalist, for it depends on a reduction in the time taken to produce the worker’s means of subsistence, and thus involves a large number of capitalists improving their methods of production.

Thus relative SV is produced by the generalised development of the productivity of labour in those industries that supply the means of subsistence or means of production of means of subsistence.

Hence improvements in the productivity of labour in industries producing ‘luxury’ goods do not affect the rate of surplus value – they simply cheapen capitalists’ consumption goods.

Improvements in productivity do not benefit the capitalist who introduces them as much as they benefit all capitalists taken together. If the productivity of labour in baking is improved so that bread is cheapened and money wages correspondingly reduced, the gains accrue to all capitalists, not only to the bakers.

Why do individual capitalists introduce these improvements in productivity?

It is competition that drives each individual capitalist to increase the productivity of labour.

If a capitalist can improve methods of production and so produce with less than the currently socially necessary labour-time, then he can make extra profits, since the price will still correspond to the old methods of production.

As other capitalists introduce the new methods of production the price will fall and the extra profits will be eroded.

Thus every capitalist will seek to improve the productivity of labour to increase his profits, or to defend his profits from competitive erosion.

In the short-run the extra profits produced will accrue to the capitalist who introduced the new technique. But soon competition will erode this extra profit and the price of the commodity will fall.

If this commodity enters into the production of the workers’ means of consumption, or enters their means of consumption directly, the fall in price will reduce the value of labour-power, and so the necessary labour-time, and so increase the rate of SV for all capitalists.

If it is a luxury item the cost of living of capitalist will fall, but there will be no increase in SV (pp. 433-7)

It is important to understand that the earning of extra profits by an individual capitalist who introduces an improved method of production is not the same thing as the production of relative SV, which involves the capitalist system as a whole.

In particular, the capitalist who produces luxury goods can earn an extra profit, but make no contribution to increasing relative SV.

Thus the individual capitalist seeks to economise on labour, to reduce the amount of labour needed to make his product. The implication of the constant advance of productivity for the system as a whole, however, is a “cheapening of the worker”, a reduction of the value of labour-power, and so an increase in SV.

Thus SV can be increased not only by extending the working day, but also, as capital transforms methods of production, by increasing the productivity of labour.


Chapter 13 – Co-operation

Chapters 13, 14 and 15 deal with the progressive transformation of the mode of production carried out as capital took hold of production.

It is the progressive transformation of the mode of production that leads to the steady increase in the productivity of labour and so the production of relative SV.

Chapter 13 considers ‘cooperation’ which is the basis of all capitalist production: the bringing together of a large number of workers under the command of a single capitalist.

Initially capital simply increases the scale of handicraft production. This increase in scale has its effects:

  1. the differences between individual workers are evened out, so that labour comes to have from the start a socially average character
  2. the increase in scale “produces a revolution in the objective conditions of the labour process”, e.g. buildings are transformed and economies of scale reduce costs of production even before the labour process itself is affected.

It is only capital that can bring the workers together (in a capitalist society)

The increase in productivity that becomes possible with cooperation appears to be the product of capital itself: the productive power of collective labour appears to be a “productive power inherent in capital” (p. 451)


Chapter 14 – The Division of Labour and Manufacture

This chapter considers the development of manufacture, the form of cooperation based on the division of labour.

Manufacture assembles specialised workers in one place and breaks down the process of production into a series of distinct tasks.

This divides up the skills of handicraft production to give a labour force of workers with very narrow specialisations, on the one hand, and unskilled workers, on the other.

It is only through the exchange of products as commodities that labour of different forms is brought into contact with one another.

Manufacturing not only leads to the extreme specialisation of labour, but also to the extreme specialisation of tools and from this develops the machine.

Machinery makes possible the expansion in the employment of women and children, it imposes a further lengthening of the working day, it leads to intensification of labour, which is the inevitable corollary of the shortening of the working day as capitalists try to pack more labour into the shorter time (so generating renewed pressure for a shorter working day).

Social relations in the factory: the deskilling of labour, the domination of man by machine, the separation of mental from manual labour, the rigid discipline, the use of the machine as a weapon in the struggle of capital against labour and the worker’s illusion that it is the machine, rather than capital, that oppresses him.


Chapter 15 – Machinery and Large-Scale Industry

The impact of machinery on employment: it may throw workers out of work.

Although increased accumulation creates more jobs, even when workers can get new employment their situation becomes unstable: in and out of work.

Cyclical fluctuations become important.
