With respect to the pure monopolist's demand curve,it can be said that:

A) the stronger the barriers to entry,the more elastic is the monopolist's demand curve.
B) price exceeds marginal revenue at all outputs greater than 1.
C) demand is perfectly inelastic.
D) marginal revenue equals price at all outputs.

The demand curve for a monopolist is downward sloping, meaning as price decreases, quantity demanded increases. This results in a situation where, for all outputs greater than one, the price (what consumers are willing to pay for the next unit) exceeds the marginal revenue (the additional revenue the firm makes from selling one more unit). This discrepancy occurs because to sell more units, a monopolist must lower the price on all units sold, not just the additional unit, thus reducing the revenue gained from previously sold units. Choices A, C, and D are incorrect descriptions of a monopolist's demand curve characteristics.
