Capital, Volume II Wikipedia
Volume II is divided into three parts:
- The Metamorphoses of Capital and Their Circuits
- The Turnover of Capital
- The Reproduction and Circulation of the Aggregate Social Capital
In this book, the main ideas behind the marketplace are to be found: how value and surplus-value are realized. Its dramatis personae, not so much the worker and the industrialist (as in Volume I), but rather the money owner (and money lender), the wholesale merchant, the trader and the entrepreneur or 'functioning capitalist.' Moreover, workers appear in Volume II, essentially as buyers of consumer goods and, therefore, as sellers of the commodity labour power, rather than producers of value and surplus-value (although, this latter quality, established in Volume I, remains the solid foundation on which the whole of the unfolding analysis is based).
Marx wrote in a letter sent to Engels on 30 April 1868: 'In Book 1. . . we content ourselves with the assumption that if in the self-expansion process £100 becomes £110, the latter will find already in existence in the market the elements into which it will change once more. But now we investigate the conditions under which these elements are found at hand, namely the social intertwining of the different capitals, of the component parts of capital and of revenue (= s).' This intertwining, conceived as a movement of commodities and of money, enabled Marx to work out at least the essential elements, if not the definitive form of a coherent theory of the trade cycle, based upon the inevitability of periodic disequilibrium between supply and demand under the capitalist mode of production (Mandel, 1978, Intro to Vol. II of Capital).
Part 3 is the point of departure for the topic of capital accumulation, which was given its Marxist treatment later in detail by, among others, Rosa Luxemburg.
