Answer:
Lies below its demand curve and is steeper than its demand curve.
Explanation:
The marginal revenue curve for a monopolist lies below the demand curve because of the quantity effect. The quantity effect refers to the fact that even a monopolist must lower its price if it wants to sell a larger quantity of goods or services.
The slope of the marginal revenue curve is steeper than the demand curve because it reflects the market power of the monopolist. Instead, the marginal revenue curve for a perfectly competitive firm (with 0 market power) is horizontal or perfectly elastic.
