MARGINAL FACTOR COST, PERFECT COMPETITION: The change in total factor cost resulting from a change in the quantity of factor input employed by a perfectly competitive firm. Marginal factor cost, abbreviated MFC, indicates how total factor cost changes with the employment of one more input. It is found by dividing the change in total factor cost by the change in the quantity of input used. Marginal factor cost is compared with marginal revenue product to identify the profit-maximizing quantity of input to hire.

TAX WEDGE

The difference between demand price and supply price that is created when a tax is imposed on a market. Placing a tax on a market disrupts what otherwise would be an equilibrium equality between demand price and supply price. A tax wedge results because the tax is included in the demand price paid by buyers but not in the supply price received by sellers. With standard demand (negative slope) and supply (positive slope) curves, the incidence of the tax (who pays) is divided between buyers and sellers.
