Perfect Competition

The Theory of the Firm studies the profit-maximizing behavior of a firm, and that behavior depends in part on the demand curve the firm faces.  There are two interesting cases.  Under Perfect Competition, the firm faces a horizontal demand curve.  It can sell any quantity desired at the market price, but cannot sell anything above the market price.  Under Monopoly / Monopolistic Competition, the firm faces a downward sloping demand curve.  Its price does affect the quantity sold either because it is the only firm in the market (a monopoly) or because the products in its market are not perfect substitutes (monopolistic competition).
