In capitalist society, therefore, the process of reproduction as a whole, constitutes a peculiar and most complicated problem, in consequence of these purely historical and social factors. There is, as we shall see, an external characteristic which shows clearly this specific historical peculiarity of the capitalist process of reproduction. Comprising not only production but also circulation (the process of exchange), it unites these two elements. Capitalist production is primarily production by innumerable private producers without any planned regulation. The only social link between these producers is the act of exchange. In taking account of social requirements reproduction has no clue to go on other than the experiences of the preceding labour period. These experiences, however, remain the private experiences of individual producers and are not integrated into a comprehensive and social form. Moreover, they do not always refer positively and directly to the needs of society. They are often rather indirect and negative, for it is only on the basis of price fluctuations that they indicate whether the aggregate of produced commodities falls short of the effective demand or exceeds it. Yet the individual private producers make recurrent use of these experiences of the preceding labour period when they re-engage in reproduction, so that glut or shortage are bound to occur again in the following period. Individual branches of production may develop independently, so that there may be a surplus in one branch and a deficiency in another. But as nearly all individual branches of production are interdependent technically, glut or shortage in some of the larger branches of production lead to the same phenomenon in most of the others. Thus the general supply of products may alternate periodically between shortage and surplus relative to the social demand.
Herein lies the peculiar character of reproduction in a capitalist society, which differs from all other known forms of production. In the first place, every branch of production develops independently within certain limits, in a way that leads to periodical interruptions of production of shorter or longer duration. Secondly, the individual branches of reproduction show deviations from social requirements amounting to all-round disparity and thus resulting in a general interruption of reproduction. These features of capitalist reproduction are quite characteristic. In all other economic systems, reproduction runs its uninterrupted and regular course, apart from external disturbance by violence. Capitalist reproduction, however, to quote Sismondi’s well-known dictum, can only be represented as a continuous sequence of individual spirals. Every such spiral starts with small loops which become increasingly larger and eventually very large indeed. Then they contract, and a new spiral starts again with small loops, repeating the figure up to the point of interruption. This periodical fluctuation between the largest volume of reproduction and its contraction to partial suspension, this cycle of slump, boom, and crisis, as it has been called, is the most striking peculiarity of capitalist reproduction.
It is very important, however, to establish quite firmly and from the very outset that this cyclical movement of boom, slump, and crisis, does not represent the whole problem of capitalist reproduction, although it is an essential element of it. Periodical cycles and crises are specific phases of reproduction in a capitalist system of economy, but not the whole of this process. In order to demonstrate the pure implications of capitalist reproduction we must rather consider it quite apart from the periodical cycles and crises. Strange as this may appear, the method is quite rational; it is indeed the only method of inquiry that is scientifically tenable. In order to demonstrate and to solve the problem of pure value we must leave price fluctuations out of consideration. The approach of vulgar economics always attempts to solve the problem of value by reference to fluctuations in demand and supply. Classical economists, from Adam Smith to Karl Marx, attack the problem in the opposite way, pointing out that fluctuations in the mutual relation between demand and supply can explain only disparities between price and value, not value itself. In order to find the value of a commodity, we must start by assuming that demand and supply are in a state of equilibrium, that the price of a commodity and its value closely correspond to one another. Thus the scientific problem of value begins at the very point where the effect of demand and supply ceases to operate.
In consequence of periodical cycles and crises capitalist reproduction fluctuates as a rule around the level of the effective total demand of society, sometimes rising above and sometimes falling below this level, contracting occasionally even to the point of almost complete interruption of reproduction. However, if we consider a longer period, a whole cycle with its alternating phases of prosperity and depression, of boom and slump, that is if we consider reproduction at its highest and lowest volume, including the stage of suspension, we can set off boom against slump and work out an average, a mean volume of reproduction for the whole cycle. This average is not only a theoretical figment of thought, it is also a real objective fact. For in spite of the sharp rises and falls in the course of a cycle, in spite of crises, the needs of society are always satisfied more or less, reproduction continues on its complicated course, and productive capacities develop progressively. How can this take place, leaving cycles and crises out of consideration? Here the real question begins. The attempt to solve the problem of reproduction in terms of the periodical character of crises is fundamentally a device of vulgar economics, just like the attempt to solve the problem of value in terms of fluctuations in demand and supply. Nevertheless, we shall see in the course of our observations that as soon as economic theory gets an inkling of the problem of reproduction, as soon as it has at least started guessing at the problem, it reveals a persistent tendency suddenly to transform the problem of reproduction into the problem of crises, thus barring its own way to the solution of the question. When we speak of capitalist reproduction in the following exposition, we shall always understand by this term a mean volume of productivity which is an average taken over the various phases of a cycle.
Now, the total of capitalist reproduction is created by an unlimited and constantly changing number of private producers. They produce independently of one another; apart from the observation of price fluctuations there is no social control—no social link exists between the individual producers other than the exchange of commodities. The question arises how these innumerable disconnected operations can lead to the actual total of production. This general aspect of our problem indeed strikes us immediately as one of prime importance. But if we put it this way, we overlook the fact that such private producers are not simply producers of commodities but are essentially capitalist producers, that the total production of society is not simply production for the sake of satisfying social requirements, and equally not merely production of commodities, but essentially capitalist production.
Let us examine our problem anew in the light of this fact. A producer who produces not only commodities but capital must above all create surplus value. The capitalist producer’s final goal, his main incentive, is the production of surplus value. The proceeds from the commodities he has manufactured must not only recompense him for all his outlay, but in addition they must yield him a value which does not correspond with any expense on his part, and is pure gain. If we consider the process of production from the point of view of the creation of surplus value, we see that the capital advanced by the capitalist is divided into two parts: the first part represents his expenses on means of production such as premises, raw material, partly finished goods and machinery. The second part is spent on wages. This holds good, even if the capitalist producer does not know it himself, and in spite of the pious stuff about fixed and circulating capital with which he may delude himself and the world. Marx called this first part constant capital. Its value is not changed by its utilisation in the labour process—it is transferred in toto to the finished product. The second part Marx calls the variable capital. This gives rise to an additional value, which materialises when the results of unpaid labour are appropriated. The various components which make up the value of every commodity produced by capitalist methods may be expressed by the formula: c + v + s. In this formula c stands for the value of the constant capital laid out in inanimate means of production and transferred to the commodity, v stands for the value of the variable capital advanced in form of wages, and s stands for the surplus value, the additional value of the unpaid part of wage labour. Every type of goods shows these three components of value, whether we consider an individual commodity or the aggregate of commodities as a whole, whether we consider cotton textiles or ballet performances, cast-iron tubes or liberal newspapers. Thus for the capitalist producer the manufacture of commodities is not an end in itself, it is only a means to the appropriation
