4. Study Questions and Problems #4Consider this statement: "Because price equals long-run average cost and profits are zero, a monopolistically competitive firm is efficient." Do youagree or disagree?Agree, because a monopolistically competitive firm produces a socially optimal output.Disagree, because a monopolistically competitive firm does not produce enough output from a socially optimal point of view.Disagree, because a monopolistically competitive firm produces too much output from a socially optimal point of view.

When there is monopolistic competition, businesses produce at a level where their prices are higher…

Q. 2
c-State and explain briefly 2 differences between a perfectly competitive market and a monopolistic competitive market.
Because this market is monopolistically competitive, you can tell that it is in long-run equilibrium by the fact that at the optimal quantity for each firm. Further, the quantity the firm produces in long-run equilibrium is the efficient scale. True or False: This indicates that there is excess capacity in the market for jackets. O True False Monopolistically competitive markets may be socially inefficient due to the presence of too many or too few firms. The presence of the externality implies that there is too much entry of new firms in the market.
5. How do monopolistically competitive markets differ from competitive markets? If monopolistically competitive firms are making economic profits in the short run, what happens in the long run?
4. Comparing monopolistic competition and perfect competition Suppose that a firm produces tennis racquets in a monopolistically competitive market. The following graph shows its demand curve (D), marginal revenue curve (MR), marginal cost curve (MC), and long-run average cost curve (LRAC). Assume that all firms in the industry face the same cost structure. Place the tan point (dash symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Next, place the purple point (diamond symbol) to indicate the point at which this firm would produce in the long run if it operated in a perfectly competitive market. Note: Dashed drop lines will automatically extend to both axes.

The graph depicts a monopolistically competitive firm. Assuming the firm's ATC is ATC', the firm's current economic profit (per day) is_____, and its long-run economic profit is _____. Price and cost $40 30 23 20 10 0 $3,000; $0 $1,500; $0 $1,500; $2,500 $4,000; $3,000 MR 150 200 MC ATC ATC AR=D Quantity (per day)
1. If the demand for a good increases at the same time as the supply of the same good decreases, what will happen to the equilibrium price and quantity of the good? Explain. 2. What is the deadweight loss of monopoly? Show the deadweight loss when the monopolist can perfectly price discriminate. 3. What is the point of long run equilibrium of a monopolistically competitive firm. How does it compare to a competitive firm.
1. Briefly discuss the various ways monopolistically competitive firms can differentiate their products? 2. In the long-run, a perfectly competitive firm will earn what kind of economic profit?
The diagram below describes a monopolistically competitive firm in long-run equilibrium. On the diagram illustrate. a. The quantity of output, qo , that maximizes profit. b. The quantity of output, qfe , that would represent the firm’s full capacity. c. The quantity of output, qs , that would represent the socially optimal output level.
Using only things found in an average home, please provide one example of something from each kind of market, and briefly explain why this thing is in that particular market. Try to be creative. You will need an example of something from a: Perfectly competitive market Imperfectly competitive market (monopolistically competition or oligopoly), and Monopoly market
3. Is monopolistic competition efficient? Suppose that a firm produces wooden train engines in a monopolistically competitive market. The following graph shows its demand curve, marginal- revenue (MR) curve, marginal-cost (MC) curve, and average-total-cost (ATC) curve. Place a black point (plus symbol) on the graph to indicate the long-run monopolistically competitive equilibrium price and quantity for this firm. Next, place a grey point (star symbol) to indicate the minimum average total cost the firm faces and the quantity associated with that cost. ? PRICE (Dollars per engine) 100 90 80 70 60 50 40 30 20 10 MC ATC MR 0 + Demand H 0 10 20 30 40 50 60 70 80 90 100 QUANTITY (Thousands of engines) Mon Comp Outcome Min Unit Cost Because this market is a monopolistically competitive market, you can tell that it is in long-run equilibrium by the fact that optimal quantity for each firm. Furthermore, the quantity the firm produces in long-run equilibrium is True or False: This indicates…
