Price-taking firm’s decision regarding the quantity of an input to employ. The value of the marginal product of an input, VMP, is the marginal product of the input times the price of the output; VMP = MP•P. Example: Suppose that the MPL is 1.5 shirts per hour and the price of shirts is $6 per shirt. A worker working one hour will yield the firm $9.00 in additional revenues.
Suppose that the market price of the output produced by a firm is $0.50 per unit and the market price of labor is $8.00 per hour.
A firm’s demand for an input is based upon the input’s VMP, which depends upon the input’s marginal productivity and the output’s value (price) in the market; VMP = MP • P.

Marginal Productivity Theory of Income Determination: In a market economy the distribution of income depends upon the distribution of resource (input) ownership and the prices of those factors of production. The prices of inputs are determined by supply and demand in the markets for those inputs. The importance of the marginal productivity of inputs in determining the distribution of income follows from the fact that the demands for inputs directly depends upon the values of their marginal products.

Why has the gap in earnings between skilled and unskilled workers risen in recent years? • International trade has altered the relative demand for skilled and unskilled labor. • Changes in technology have altered the relative demand for skilled and unskilled labor.
