 although the one form may be more favorable to the development of capitalist production than the other.

Let the ordinary working day contain 12 hours of which 6 are paid, 6 unpaid. Let its value-product be 6 shillings, that of one hour’s labour therefore 6d. Let us suppose that, as the result of experience, a labourer who works with the average amount of intensity and skill, who, therefore, gives in fact only the time socially necessary to the production of an article, supplies in 12 hours 24 pieces, either distinct products or measurable parts of a continuous whole. Then the value of these 24 pieces, after subtraction of the portion of constant capital contained in them, is 6 shillings, and the value of a single piece 8d. The labourer receives 1$1⁄2$d. per piece, and thus earns in 12 hours 8 shillings. Just as, with time-wages, it does not matter whether we assume that the labourer works 6 hours for himself and 6 hours for the capitalist, or half of every hour for himself, and the other half for the capitalist, so here it does not matter whether we say that each individual piece is half paid, and half unpaid for, or that the price of 12 pieces is the equivalent only of the value of the labour-power, whilst in the other 12 pieces surplus-value is incorporated.

The form of piece-wages is just as irrational as that of time wages. Whilst in our example two pieces of a commodity, after subtraction of the value of the means of production consumed in them, are worth 6d. as being the product of one hour, the labourer receives for them a price of 3d. Piece-wages do not, in fact, distinctly express any relation of value. It is not, therefore, a question of measuring the value of the piece by the working time incorporated in it, but on the contrary of measuring the working-time the labourer has expended, by the number of pieces he has produced. In time-wages the labour is measured by its immediate duration, in piece-wages by the quantity of products in which the labour has embodied itself during a given time. The price of labour-time itself is finally determined by the equation; value of a day’s labour=daily
