Which feature best separates monopolistic competition from perfect competition?
A. There is only one firm.
B. Entry is blocked forever.
C. Firms do not maximise profit.
D. Products are differentiated, so each firm faces a downward-sloping demand curve.✓ 答案
解說
Both structures can have free entry. Monopolistic competition has many firms and differentiated products, so demand for one firm slopes down. A single firm would be monopoly. Profit maximisation is still the usual assumption.
