constant

A horizontal supply curve means that there is BLANK average cost.

A profit-maximizing monopolist will always be selling at a price where demand is (elastic/inelastic/unit elastic).

second

A two-part tariff is a form of (first/second/third)-degree price discrimination.

demand

Among the factors that determine the extent of a firm's monopoly power are the elasticity of the market BLANK curve and the elasticity of the supply by other firms, and the number of rival firms. (WRITE ENTIRE WORD)

supply

no

The constant-cost industry refers to the fact that a firm's cost curves do not shift. Does that mean that every firm has a horizontal LAC curve?

AR

The demand curve is the same as the BLANK curve.
