Topic: The Cost Curves <=PAGE BACK | PAGE NEXT=>

  • The cost side of the firm's production can be conveniently displayed using the U-shaped cost curves:

    • Average Total Cost (ATC): This curve is negatively-sloped for small quantities of output, then becomes positively-sloped for larger quantities of output.

    • Marginal Cost (MC): Like the average total cost curve, the marginal cost curve is negatively-sloped for small quantities of output, then becomes positively-sloped for larger quantities of output.

  • Both curves play important roles in the analysis of the short-run production decision for monopolistic competition.

MARGINAL REVENUE CURVE, PERFECT COMPETITION

A curve that graphically represents the relation between the marginal revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve. A perfectly competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.
