FACTOR DEMAND AND MARGINAL REVENUE PRODUCT: For a firm that hires the services of a factor in a perfectly competitive factor market, the factor demand curve is that portion of the marginal revenue product curve that lies below the average revenue product curve. The relation between marginal revenue product and factor demand for a perfectly competitive firm is comparable to the relation between marginal cost and short-run supply. A perfectly competitive firm maximizes profit by hiring the quantity of a factor that equates factor price and marginal revenue product. As such, the firm moves along it's marginal revenue product curve in response to alternative factor prices.

ASSUMPTIONS, CLASSICAL ECONOMICS Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.
