MARGINAL COST CURVE: A curve that graphically represents the relation between marginal cost incurred by a firm in the short-run product of a good or service and the quantity of output produced. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables, like technology and resource prices, constant. The marginal cost curve is U-shaped. Marginal cost is relatively high at small quantities of output, then as production increases, declines, reaches a minimum value, then rises. This shape of the marginal cost curve is directly attributable to increasing, then decreasing marginal returns (and the law of diminishing marginal returns).

Topic: Competition <=PAGE BACK | PAGE NEXT=>

Competition (especially our fourth rule of competition) brings out the best among buyers and sellers, that is, efficient use of resources.
  • Competition among sellers forces them to supply the most wanted products at the lowest resource cost.
  • Competition among buyers forces them to spend their limited incomes on the most satisfying goods.
  • Less competition among sellers than among buyers lets the sellers charge higher prices.
  • Less competition among buyers than among sellers lets the buyers pay lower prices.

INELASTIC SUPPLY

The general elasticity relation in which relatively large changes in price cause relatively small changes in quantity supplied. Large changes in price cause relatively small changes in quantity supplied or the percentage change in quantity supplied is smaller than the percentage change in price. This characterization of elasticity is most important for the price elasticity of supply. Inelastic supply is one of two general elasticity relations for supply. The other is elastic supply.
