- D.Perfectly inelastic
Show answer
Explanation
The correct answer is A, Relatively elastic. Under monopolistic competition a single firm faces a demand curve that is relatively elastic, so it slopes downward but is fairly flat.
In this market form there are many sellers offering closely similar but differentiated products, as with soaps, toothpastes or restaurants. Because close substitutes are available, a firm that raises its price loses a large part of its sales, which makes demand highly responsive to price. Yet because its product is not identical to the others, it keeps some pricing power and does not lose all its buyers, so demand is not perfectly elastic. Selling costs such as advertising are a feature of this market.
Option B, perfectly elastic, describes perfect competition, where the firm is a price taker and its demand curve is horizontal. Options C and D, relatively and perfectly inelastic, do not apply where substitutes are easy to find.
Exam tip: perfect competition means horizontal demand; monopolistic competition means a flat but downward sloping curve.
