As a rule, an increased production of surplus value results from an increase of capital brought about by addition of part of the appropriated surplus value to the original capital, no matter whether this capitalist surplus value is used for the expansion of an old enterprise or for founding a new one, an independent offshoot. Capitalist expanding reproduction thus acquires the specific characteristics of an increase in capital by means of a progressive capitalisation of surplus value, or, as Marx has put it, by the accumulation of capital.
The general formula for enlarged reproduction under the rule of capital thus runs as follows: c + v + s⁄x + s´. Here s⁄x stands for the capitalised part of the surplus value appropriated in an earlier period of production; s´ stands for the new surplus value created by the increased capital. Part of this new surplus value is capitalised again, and expanding reproduction is thus, from the capitalist point of view, a constantly flowing process of alternate appropriation and capitalisation of surplus value.
So far, however, we have only arrived at a general and abstract formula for reproduction. Let us now consider more closely the concrete conditions which are necessary to apply this formula.
The surplus value which has been appropriated, after it has successfully cast off its commodity-form in the market, appears as a given amount of money. This money-form is the form of its absolute value, the beginning of its career as capital. But as it is impossible to create surplus value with money, it cannot, in this form, advance beyond the threshold of its career. Capital must assume commodity-form, so that the particular portion of it which is earmarked for accumulation can be capitalised. For only in this form can it become productive capital; that is, capital begetting new surplus value. Therefore, like the original capital, it must again be divided into two parts; a constant part, comprising the inanimate means of production, and a variable part, the wages. Only then will our formula c + v + s apply to it in the same way as it applied to the old capital.
But the good intent of the capitalist to accumulate, his thrift and abstinence which make him use the greater part of his surplus value for production instead of squandering it on personal luxuries, is not sufficient for this purpose. On the contrary, it is essential that he should find on the commodity market the concrete forms which he intends to give his new surplus value. In the first place, he must secure the material means of production such as raw materials, machines etc. required for the branch of production he has chosen and planned, so that the particular part of the surplus value which corresponds to his constant capital may assume a productive form. Secondly, the other, variable part of his surplus value must also be convertible, and two essentials are necessary for this conversion: of first importance, the labour market must offer a sufficient quantity of additional labour, and secondly, as the workers cannot live on money alone, the commodity market, too, must offer an additional amount of provisions, which the workers newly to be employed may exchange against the variable part of the surplus value they will get from the capitalist.
All these prerequisites found, the capitalist can set his capitalised surplus value to work and make it, as operating capital, beget new surplus value. But still his task is not completely done. Both the new capital and the surplus value produced still exist for the time being in the shape of an additional quantity of some commodity or other. In this form the new capital is but advanced, and the new surplus value created by it is still in a form in which it is of no use to the capitalist. The new capital as well as the surplus value which it has created must cast off their commodity-form, re-assume the form of pure value, and thus revert to the capitalist as money. Unless this process is successfully concluded, the new capital and surplus value will be wholly or partly lost, the capitalisation of surplus value will have miscarried, and there will have been no accumulation. It is absolutely essential to the accumulation of capital that a sufficient quantity of commodities created by the new capital should win a place for itself on the market and be realised.
Thus we see that expanding reproduction as accumulation of capital in a capitalist system is bound up with a whole series of special conditions. Let us look at these more closely. The first condition is that production should create surplus value, for surplus value is the elementary form in which alone increased production is possible under capitalist conditions. The entire process of production must abide by this condition when determining the relations between capitalist and worker in the production of commodities. Once this first condition is given, the second is that surplus value must be realised, converted into the form of money, so that it can be appropriated for the purposes of expanding reproduction. This second condition thus leads us to the commodity market. Here, the hazards of exchange decide the further fate of the surplus value, and thus the future of reproduction. The third condition is as follows: provided that part of the realised surplus value has been added to capital for the purpose of accumulation, this new capital must first assume its productive form of labour and inanimate means of production. Moreover, that part of it which had been exchanged for labour must be converted into provisions for the workers. Thus we are led again to the markets of labour and commodities. If all these requirements have been met and enlarged reproduction of commodities has taken place, a fourth condition must be added: the additional quantity of commodities representing the new capital plus surplus value will have to be realised, that is, reconverted into money. Only if this conversion has been successful, can it be said that expanding capitalist reproduction has actually taken place. This last condition leads us back to the commodity market.
Thus capitalist production and reproduction imply a constant shifting between the place of production and the commodity market, a shuttle movement from the private office and the factory where unauthorised persons are strictly excluded, where the sovereign will of the individual capitalist is the highest law, to the commodity market where nobody sets up any laws and where neither will nor reason assert themselves. But it is this very licence and anarchy of the commodity market which brings home to the individual capitalist that he is dependent upon society, upon the entirety of its producing and consuming members. The individual capitalist may need additional means of production, additional labour and provisions for these workers in order to expand reproduction, but whether he can get what he needs depends upon factors and events beyond his control, materialising, as it were, behind his back. In order to realise his increased aggregate of products, the individual capitalist requires a larger market for his goods, but he has no control whatever over the actual increase of demand in general, or of the particular demand for his special kind of good.
The conditions we have enumerated here, which all give expression to the inherent contradiction between consumption and private production and their social interconnection, are nothing new, and it is not only at the stage of reproduction that they become apparent. These conditions express the general contradiction inherent in capitalist production. They involve, however, particular difficulties as regards the process of reproduction for the following reasons. With regard to reproduction, especially expanding reproduction, the capitalist method of production not only reveals its general fundamental character, but, what is more, it shows, in the various periods of production, a definite rhythm within a continuous progression—the characteristic interplay of individual wills. From this point of view, we must inquire
