Document Summary

Factor prices help determine money incomes, and they simultaneously ration factors of production to various industries and firms. The demand for any factor is derived from the product it helps produce: that means the demand for a factor will depend on its productivity and on the market value (price) of the good it is producing. If factors c and d are complementary or jointly demanded, there is only an output effect; a change in the price of c will change the demand for d in the opposite direction. The elasticity of demand for a factor measures the responsiveness of producers to a change in the factor"s price. The coefficient of the elasticity of factor demand is: When efd is greater than 1, factor demand is elastic; when efd is less than 1, factor demand is inelastic; and when efd equals 1, factor demand is unit elastic.
