Merchant’s Capital, an isolated part of industrial capital functioning in the turnover sphere and servicing the sale of commodities and of the surplus value they contain. In pre-capitalist formations, merchant’s capital was an independent and the dominant form of capital. It facilitated the development of commodity-money relations, the ruin of petty commodity producers and the accumulation of considerable sums of money in the hands of individual exploiters. This engendered the capitalist mode of production. The developed capitalist economy is characterised by a division of the functions of the production and sale of goods between merchant and industrial capitalists. When trade separates from industry and a group of capitalists specialise in buying and selling commodities thus acquiring a specific sphere of application of capital—the turnover sphere, then a part of the capital separates itself from industrial capital and forms merchant’s capital, which functions in two forms—commodity and money and in its movement passes through two stages: the purchase of commodities (M—C) and the sale of commodities (C—M). Certain expenditures are made in the process of commodity turnover, and these are subdivided into net and additional circulation costs. Merchant’s capital functions in capitalist trade, which has two main forms: wholesale trade (the sale of goods in large batches) and retail trade (sales to consumers). Merchant’s capital does not take a direct part in manufacturing goods and creating surplus value, but it facilitates the turnover of industrial capital, boosts output and realises the surplus value these goods include. Merchant capitalists, like industrialists, set up their enterprises in order to make profit. The separation of merchant’s from industrial capital aggravates the contradiction between production and consumption inherent in capitalism. Selling finished goods to merchant capitalists, industrialists do not care about what happens further to them and continue to manufacture goods, often overpacking already packed warehouses and thus aggravating the hnvic contradiction of capitalism.
