Correct answer: C. The monopolist makes economic profits in the long run while the monopolistic competitor makes zero economic profits in the long run
- A. the monopolist faces a downward-sloping demand curve while the monopolistic competitor faces an elastic demand curve
- B. the monopolist charges a price above marginal cost while the monopolistic competitor charges a price equal to marginal cost
- C. The monopolist makes economic profits in the long run while the monopolistic competitor makes zero economic profits in the long run
