Pricing of Factors of Production

Answer 1

Whenever we have touched on the pricing of productive factors we have signified the prices of their unit services, i.e., their rents. In order to set aside consideration of the pricing of the factors as "wholes," as embodiments of a series of future unit services, we have been assuming that no businessmen purchase factors (whether land, labor, or capital goods) outright, but only unit services of these factors. This assumption will be continued for the time being. Later on, we shall drop this restrictive assumption and consider the pricing of "whole factors." When all factors are specific there is no principle of pricing that we can offer. Practically, the only thing that economic analysis can say about the pricing of the productive factors in such a case is that voluntary bargaining among the factor-owners will settle the issue. As long as the factors are all purely specific, economic analysis can say little more about the determinants of their pricing. What conditions must apply, then, to enable us to be more definite about the pricing of factors? The currently fashionable account of this subject hinges on the fixity or variability in the proportions of the combined factors used per unit of product. If the factors can be combined only in certain fixed proportions to produce a given quantity of product, it is alleged, then there can be no determinate price; if the pro­portions of the factors can be varied to produce a given result, then the pricing of each factor can be isolated and determined. Let us examine this contention. Suppose that a product worth 20 gold ounces is produced by three factors, each one purely spe­cific to this production. Suppose that the proportions are variable, so that a product worth 20 gold ounces can be produced either by four units of factor A, five units of factor B, and three units of factor C, or by six units of A, four units of B, and two units of C. How will this help the economist to say anything more about the pricing of these factors than that it will be determined by bargaining? The prices will still be determined by bargaining, and it is obvious that the variability in the proportions of the factors does not aid us in any determination of the specific value or share of each particular product. Since each factor is purely specific, there is no way we can analytically ascertain how a price for a factor is ob­tained. The fallacious emphasis on variability of proportion as the basis for factor pricing in the current literature is a result of the prevailing method of analysis. A typical single firm is considered, with its selling prices and prices of factors given. Then, the pro­portions of the factors are assumed to be variable. It can be shown, accordingly, that if the price of factor A increases com­pared to B, the firm will use less of A and more of B in produc­ing its product. From this, demand curves for each factor are de­duced, and the pricing of each factor established.
