Part 13

All capital that is embarked on a productive undertaking consists of two parts: one part is expended on the technical means of production--on buildings, machines, tools, and raw materials, the other on wages. The first part Marx calls Constant Capital (c), the other part Variable Capital (v). The first is called constant, because it only adds to the commodities just as much value as it loses in the course of the productive process; it creates no fresh value: Marx also calls it the passive portion. The outlay on wages is called variable capital because it undergoes an alteration in the process of production: it creates new additional value: Marx also called variable capital the active portion, for it creates surplus value (s).

This composition of capital of constant and variable parts Marx calls its organic composition. He calls it average or normal composition when the capital of a business is 80 per cent. constant and 20 per cent. variable. If the constant part is higher, and the variable part lower, he calls it capital of a high composition.

Capital of under 80 per cent. constant portion and over 20 per cent. variable portion he calls capital of a lower composition. And rightly, because the higher the ladder of capitalist production is, the more costly and extensive are the machinery and factory buildings and the greater is the outlay on raw materials, whereas primitive businesses employ less machinery, cheaper workshops, but a relatively greater number of workers. The relation between (c) and (v) reveals at the same time the stage to which production has developed.

Thus, according to Marx, it is solely the variable capital which creates surplus value, or, as it is commonly expressed, profit. We have seen above, in the explanation of the nature of wages, why variable capital creates more value than it is paid for by the capitalist; the worker does indeed receive the exchange value of his labour power, but the use value of the labour power functions, we have assumed, twice as many hours as are necessary for its reproduction. This surplus labour is embodied in surplus value. While the worker receives, let us say, a daily wage of three shillings, for the reproduction of which five hours of work suffice, his labour power will be used for ten hours. These five hours of surplus labour appear in the exchange value of the commodity, so that the value of the commodity is composed of the transferred portion of the constant capital, the outlay on wages, and the added surplus value. Immediately before the production process only constant and variable capital existed, or, in brief (c) and (v); after the completion of the production process, the commodity embodies constant and variable capital and also surplus value, or (c) and (v) and (s). This is the actual value of the commodity, (c) or, shortly expressed, c + v + s.

The relation between wages and surplus value, or between paid and unpaid labour, or, shortly, s/v, Marx calls the rate of surplus value: it expresses the degree of the exploitation of labour.

If wages amount to three shillings, which can be produced in five working hours, and if the worker works in the factory ten hours for these wages, so that he creates exchange value to the amount of six shillings, then the rate of surplus value is 100 per cent. The whole of the surplus value which arises in this manner in the process of production is called the mass of the surplus value, or shortly, m.s., that is to say, the individual rate of surplus value multiplied by the total number of workers engaged in an undertaking, or the total amount of wages.

5. Profit.

The mass of surplus value appears to the capitalist in the shape of profit. Surplus value is a Marxian scientific term which exactly expresses the principle of profit. Profit is a commercial expression which describes surplus value as it appears in practical life as a subject of experience, i.e., empirically.

The distinction between the Marxian theoretical and the commercial empirical conception is, however, not so simple: it arises from the different conceptions of the influence of capital and labour in the economic process. Let us explain it more distinctly.

As is known, Marx divided the capital embarked in industrial enterprise into two parts: into constant (technical means of production) and variable (living labour power, wages). He assumed that only the living labour power (wage labour) creates surplus value, whilst the constant capital only adds its own value to the new products.

The capitalist divides his capital outlay otherwise: into fixed (buildings and machines) and circulating (raw materials and wages) capital. The fixed capital is only used up slowly and only passes entirely into production during a series of years--let us say 15 years: thus of a fixed capital of L75,000, L5,000 would each year be consumed in the production of commodities, and written off in the balance sheet. On the other hand, the circulating capital (raw materials and wages) are wholly consumed in every period of production, and must be renewed at the beginning of a new period of production.

Suppose an industrial undertaking about to be started requires a capital expenditure of L105,000: L75,000 fixed capital (for buildings and machinery), L20,000 for raw materials, L10,000 for wages. For convenience sake, we will suppose that the period of production lasts a year, and that the rate of surplus value amounts to 100 per cent., that is, the labour power receives a payment of L10,000, and produces a value of L20,000. At the end of the year, the capitalist reckons an expenditure of L5,000 on account of fixed capital, and L30,000 of circulating capital: the commodities produced cost, therefore, a net outlay of L35,000. This is the cost price, without adding profit. According to Marx, cost price signifies (c) and (v), therefore without (s), (surplus value).

But the capitalist knows that the manufactured commodities represent a greater value than the cost price. According to Marx, the surplus value amounts to L10,000 (as the variable capital of L10,000 creates surplus value at the rate of 100 per cent.); but the capitalist adds to the cost price a profit which includes the gains of the enterprise and interest on the capital outlay. If the capitalist were alone in the market, his profit might suck up the whole of the surplus value of L10,000; but he has to reckon with competition and the state of the market. The cost price, plus profit, is the production price as established by the capitalist. But according to Marx, that is, in pure theory, the production price is equal to the cost price, plus surplus value. There is thus a quantitative distinction--a difference in the amount of money--between the theoretical and practical production price, as well as a qualitative distinction between the notions of the capitalist and Marx respecting the source of profit. The capitalist believes that profit is the result of the portion of capital which he has put into the process of production, combined with his own commercial ability. On the other hand, Marx asserts that the capitalist can only extract a profit because the wage workers (the living labour power) create a surplus value in the process of production for which they receive no payment.

We assumed that the surplus value amounted to 100 per cent. measured with variable capital, and that L10,000 expended on wages produced L20,000. The annual balance sheet, however, would show the percentage of profit to the total outlay. Consequently, we must spread the L10,000 surplus value over the L35,000 which have been expended. The surplus value of an undertaking spread over the total capital (c) Marx calls the rate of profit, or shortly, s/c = 10000/35000 = 28.58 per cent.

As a rule, the capitalist cannot sell under cost price without becoming bankrupt, but he can quite easily sell under the production price, and mostly does so. In the example already given, his rate of profit amounts to over 28 per cent. According to the degree of competition, or by reason of other circumstances which we will examine in the next chapter, he can content himself with a rate of profit of 10, 15, or 20 per cent., which will serve him partly as an income and partly be expended in the development of his enterprise. The 28 per cent. profit generally forms a circle within which he fixes his manufactured price. Under favourable circumstances he can add the whole 28 per cent, to the price; under less favourable, only 20, 15, or 10 per cent. Accordingly, several portions of surplus value remain in the commodities which are not yet realised. What happens to them? The remaining portions of profit or of surplus value fall to the large or small traders who are interposed between producer and consumer, or go in the form of interest to the banking institutions, in the event of the capitalist operating with borrowed money. As the profit is only realised in the process of circulation (in commerce and exchange) and there divided amongst the various economic classes and sections, most people believe that profit arises in commercial transactions. They do not know that the price of a commodity can only be increased in trade because its manufactured price was fixed below its price of production or its value, that is, because the commodities contain surplus value which is only gradually realised in the process of circulation.

The social significance of this doctrine is far-reaching. If it is correct, then all the social sections which are not engaged as manual and brain workers in the process of production, or in the transport of raw material, lead a parasitical life and consume the surplus value which is squeezed by the capitalist class out of the proletariat and appropriated without payment.

Quite otherwise are capitalist ideas. According to them, profit is the result both of the spirit of the enterprise and the ability of the capitalist, added to that portion of the capital which is put into the process of production: the machines and buildings and raw materials which are used up, and the labour power, all of which are bought at their proper exchange value. It is only fit and proper that the trader and moneylender should receive a portion of the profit so created, for they assist in realising the exchange value by bringing the commodities to the consumer, and thus rendering possible the process of production.

Surplus value or profit? Labour or Capital? Behind this question lurks the great class struggle of the modern social order. No wonder the Marxian doctrine of value and surplus value was the occasion for an extensive controversy, in which the famous problem of the average rate of profit played a great part.

6. The Average Rate of Profit.

According to Marx's doctrine of value and surplus value only variable capital creates fresh value and surplus value. An industrial undertaking of a lower organic composition, which thus employs much variable capital and little constant capital, must consequently create a greater surplus value or more profit than an industrial undertaking of higher composition which may employ the same total capital, but composed of greater constant and smaller variable portions than the former. Let us take two industrial capitals of L35,000 each. One expends L15,000 on the constant elements (machinery, raw materials) and L20,000 on the variable element (wages of labour). The other shows L20,000 constant part and L15,000 variable part. With an equal rate of surplus value--100 per cent.--the first capital would produce L20,000 surplus value (profit) and the other only L15,000 profit. Experience shows, however, that equal amounts of capital--in spite of temporary differences in profits--tend to produce equal profits. From this, it would appear that it is actually the capital expended and not the labour employed which determines the magnitude of the surplus value (profit), that the concrete results of the capitalist process of production do not confirm the Marxian theory of value, that the facts directly contradict the theory. It was Marx himself who drew attention to this problem. After he had constructed his theory of surplus value in the form of a scientific law, he continued: "This law clearly contradicts all experience based on appearance. Everyone knows that a cotton spinner, who, reckoning the percentage on the whole of his applied capital, employs much constant capital and little variable capital, does not, on account of this, pocket less profit or surplus value than a baker, who relatively sets in motion much variable and little constant capital."

How, then, can the equal rate of profit in the case of capitals of different organic composition be harmonised with the theory of surplus value?

Marx concedes that equal capital sums whose organic parts are unequally employed give an equal rate of profit, although the volumes of surplus value created are different. Two capital sums of L50,000 each, one of which, for example, represents L40,000 constant and L10,000 variable capital, and with a rate of surplus value of 100 per cent. gives L10,000 surplus value, while the other is composed of L10,000 constant and L40,000 variable capital, and with an equal rate of surplus value gives an amount of L40,000 surplus value, will nevertheless yield an equal rate of profit, although theoretically they would be unequal if the rate of surplus value directly determined the rate of profit. In the first case, the rate of profit would amount to 20 per cent. and in the second to 80 per cent. In reality both undertakings yield an equal rate of profit.

How is this explained, according to Marx? By means of competition, the different rates of profit are levelled to a general rate of profit, which is the average of all the various rates of profit. Thus the capitalists do not realise the surplus value as it is created in any particular factory, but in the form of average rate of profit as it is produced by the operations of the total capital of society. The average rate of profit may be lower or higher than the individual rate of profit, for the "various capitalists," as Marx explains, "so far as profits are concerned, are so many stockholders in a stock company in which the shares of profits are uniformly divided for every 100 shares of capital, so that profits differ in the case of the individual capitalists only according to the amount of capital invested by each of them in the social enterprise, according to his investment in social production as a whole, according to his shares."

While thus the individual rates of profit do not proportionately coincide with the rates of surplus value, i.e., while the degree of exploitation of the worker in the individual factory, and the volume of surplus value thus individually created, do not directly determine the individual rate of profit, it is the total mass of social surplus value which is the source of the average rate of profit. If the mass of the surplus value be large, the average rate of profit will also be great. Marx says: "It is here just the same as with average rate of interest which a usurer makes who lends out various portions of his capital at different rates of interest. The level of his average rate depends entirely on how much of his capital he has lent at each of the different rates of interest." The higher the various individual rates of interest, the higher will be the average rate of interest at which his capital has been put out.

The individual price of production signifies, therefore, cost price plus the average rate of profit, and not plus surplus value: it does not necessarily correspond with the total amount of the constant and variable portions of capital employed in an individual enterprise, plus the mass of the surplus value: the prices and magnitudes of value of commodities are not manifestly equal, as Marx has often pointed out. Of course, the total profits of the capitalist class coincide with the total surplus value extracted from the working class, provided, of course, that the supply of commodities corresponds with the social needs.

Thus the law of surplus value, in spite of all deviations and refractions, holds good in the last resort. "In theory," observes Marx, "it is assumed that the laws of the capitalist mode of production develop freely. In reality, there is always only an approximation."

And the more capitalist production develops, the greater will be the degree of approximation in particular cases, for the progress of Capitalism signifies a continuous increase of constant capital, a more mechanical character being given to industrial processes, and a reduction of variable capital to the necessary minimum, so that the differences in the organic composition of capitalist undertakings become less, thus bringing the average rate of profit and the rate of surplus value nearer to each other.

This indirect and difficult method of realising profits involves the fact that the capitalist does not distinctly observe the exploitation of wage labour practised by him, but he believes that the profit is owing to his own commercial ability.
