Sample questions

1. In a perfectly competitive market, which of the following is MOST characteristic of firms in the long run?

   1. Economic profits are positive.
   2. Firms incur economic losses.
   3. Economic profits are zero.
   4. Firms are price makers.
   Show answer

   Answer: C. Economic profits are zero.

   In perfect competition, the free entry and exit of firms in the long run ensure that firms earn only normal profits (zero economic profit). If firms were making positive economic profits, new firms would enter, increasing supply and driving down prices. If firms were incurring losses, existing firms would exit, decreasing supply and driving up prices until profits are zero.

2. The 'kinked demand curve' model is most closely associated with which market structure, and why?

   1. Perfect Competition, due to price takers.
   2. Monopolistic Competition, due to product differentiation.
   3. Oligopoly, due to price rigidity and the expectation that rivals will match price cuts but not price increases.
   4. Monopoly, due to a single seller's control over price.
   Show answer

   Answer: C. Oligopoly, due to price rigidity and the expectation that rivals will match price cuts but not price increases.

   The kinked demand curve theory, proposed by Paul Sweezy, explains price rigidity in oligopolistic markets. It suggests that if a firm lowers its price, its rivals will follow suit to avoid losing market share, resulting in a less-than-proportionate increase in the firm's sales. However, if a firm raises its price, rivals are unlikely to follow, leading to a disproportionately large decrease in the firm's sales. This creates a kink in the demand curve at the existing price, making firms hesitant to change prices.

3. Which of the following is a primary characteristic of a monopoly that distinguishes it from other market structures?

   1. Product differentiation
   2. Collusion among firms
   3. Existence of close substitutes
   4. Absence of competition
   Show answer

   Answer: D. Absence of competition

   A monopoly, by definition, is a market structure with a single seller and no close substitutes for the product. This lack of competition grants the monopolist significant market power to influence price and output decisions.

4. In the long run, a perfectly competitive firm produces at the minimum point of its Average Total Cost (ATC) curve. This statement is:

   1. True, due to zero economic profits.
   2. False, it produces where MC = ATC but not necessarily the minimum ATC.
   3. True, as firms are forced to be efficient by competition.
   4. False, only monopolies produce at minimum ATC.
   Show answer

   Answer: A. True, due to zero economic profits.

   In perfect competition, long-run equilibrium occurs when firms earn zero economic profits. This happens when price (P) equals minimum average total cost (min ATC). Since firms also produce where P = MC, and the MC curve intersects the ATC curve at its minimum point, firms are indeed forced to produce at the minimum of their ATC curve in the long run to survive.

5. Which of the following best describes the outcome for a firm in monopolistic competition in the long-run equilibrium?

   1. Price > Marginal Cost > Minimum ATC
   2. Price = Marginal Cost = Minimum ATC
   3. Price > Minimum ATC > Marginal Cost
   4. Price = Minimum ATC > Marginal Cost
   Show answer

   Answer: D. Price = Minimum ATC > Marginal Cost

   In long-run equilibrium for monopolistic competition, two conditions hold: 1) Zero economic profit, meaning Price = ATC. 2) Since the demand curve is downward sloping, P > MR. And profit maximization requires MR = MC. Therefore, P > MC. Also, for zero economic profit to be sustained in the long run with free entry, firms must produce at the lowest point of their ATC curve, which is where MC intersects ATC. Thus, Price = ATC (at its minimum) > MC.
