At long-run equilibrium in a perfectly competitive industry the typical firm is breaking even in an opportunity cost sense. T/F

Perfectly competitive markets include firms that have significant market power, with one typically being the price leader. T/F

In perfectly competitive markets, the individual firm’s demand curve is flat, while the market demand curve is typically sloping downward to the right. T/F

When a firm maximizes profits, its price is derived from where marginal revenue crosses marginal cost (extend the line up from where MR crosses MC to the Demand Curve; and then over to the Price axis (y-axis). Likewise, when you drop the line down (vertically) from the point where MR crosses MC to the Quantity axis (x-axis), this provides the point for quantity demanded.

Expert Solution

(1) T

In perfect competition, in long run equilibrium, price = MC = ATC, so firms earn only normal profit which includes opportunity costs.

(2) F

In perfect competition, there are many small firms with zero market power, so they are price takers.

(3) T

Market demand is downward sloping and firm demand curve is horizontal at market price level.

(4) T

Profit is maximized when MR = MC and corresponding price is obtained from demand curve.

Draw graphs showing a perfectly competitive firm and industry in the long-run equilibrium. a. How do you know that the industry is in long-run equilibrium? Long-run when quantity demanded=quantity supplied, no entry and not exit as firms are breaking even. (Which holds true when the P=ATC) b. Suppose that there is an increase in demand for this product. Show and explain the short-run adjustment process for both the firm and the industry. Market demand curve shifts to the right. Equilibrium...

Suppose that a perfectly competitive industry is in long-run equilibrium. Then the price of a complementary good decreases. Use two graphs, one for the firm, and one for the industry (and words) to explain what will happen in the short run, and then the long run, to: a. The market demand curve? b. The market supply curve? c. Market price? d. Market output? e. Representative firm output? f. Representative firm profit?

Consider a perfectly competitive industry at a long-run equilibrium. a. Suppose there is a sudden change in consumer preferences which increases the demand for the firm’s product. What are the effects of the change on the equilibrium of an individual firm in the short and the long run? Draw the graphs. Explain. b. Suppose there is an adverse technological shock that increases the cost of production of the firms in the industry. What are the effects of the change on...

Assume that a perfectly competitive, constant cost industry is in a long run equilibrium with 60 firms. Each firm is producing 90 units of output which it sells at the price of $41 per unit; out of this amount each firm is paying $3 tax per unit of the output. The government decides to decrease the tax, so the firms will be paying $1 tax per unit. a) Explain what would happen in the short run to the equilibrium price...

Suppose that the restaurant market is a perfectly competitive industry in long run equilibrium. Each of the identical restaurants has the same (long run) cost function: T C = 225 + q 2 , where q is the volume of sales by each establishment. Each of the identical firms therefore have the same marginal cost: MC = 2q. (a) What is the average cost function for the identical restaurants? (b) How much does each individual firm produce in the long...
