Social (Market) Value, a single value for the commodities of a given type established in the process of the intra- industry competition. Enterprises of the same industry are distinguished by different machinery, organisation of production and work, size, and other technical and economic factors. Therefore labour productivity at them is different which means that different quantities of products are manufactured in the same work time. The individual value of the commodities will also be different. In the process of intra-industry competition, different individual values level out into a single social value for all commodities of this type, which is usually determined by the individual value of the commodities manufactured under average conditions by the given industry comprising much of the products turned out by it. In exceptional cases and for a short time, social value may be regulated by poorer or better conditions of production. If demand exceeds supply and the market is in a condition to swallow goods manufactured in poorer conditions, the market value is determined by their individual value. On the contrary, if supply exceeds demand, the market value may be determined by the individual value of commodities manufactured under better conditions. Under imperialism, the process of the formation of market value is influenced by the activity of monopoly capital.
