Context

“the market-value of the entire mass, regulated as it is by the average values, is in case I equal to the sum of their individual values; although in the case of the commodities produced at the extremes, this value is represented as an average value which is forced upon them. Those who produce at the worst extreme must then sell their commodities below the individual value; those producing at the best extreme sell them above it. In case II the individual lots of commodity-values produced at the two extremes do not balance one another. Rather, the lot produced under the worse conditions decides the issue. Strictly speaking, the average price, or the market-value, of each individual commodity, or each aliquot part of the total mass, would now be determined by the total value of the mass as obtained by adding up the values of the commodities produced under different conditions, and in accordance with the aliquot part of this total value falling to the share of each individual commodity.” source
