If a profit-maximizing, competitive firm is producinga quantity at which marginal cost is between averagevariable cost and average total cost, it willa. keep producing in the short run but exit themarket in the long run.b. shut down in the short run but return toproduction in the long run.c. shut down in the short run and exit the market inthe long run.d. keep producing both in the short run and in thelong run.
A profit-maximizing firm is producing where MR = MC and has an average total cost of $4, but it gets a price of $3 for each good it sells.a. What would you advise the firm to do?
The firm should shut down in the short run and exit the market in the long run.
The firm is producing where MR = MC, so it should produce in both the short run and long run.
As long as average variable costs are less than $3, in the short run, the firm should produce. In the long run, it should exit the market.
The firm should shut down in the short run. Once the firm recoups its fixed costs, it should produce in the long run.
b. What would you advise the firm to do if you knew average variable costs were $3.50?
The firm should exit the market in the long run, but it should produce in the short run since it is covering average fixed costs.
The firm should shut down in the short run. Once the firm recoups its fixed costs, it should reopen in the long run.
The firm…

- Consider the following data: equilibrium price = $7.50, quantity of output produced 100 units, average total cost = $9, and average variable cost = $8. What will the firm do and why? = a. Shut down in the short run, because price is below average variable cost. b. Shut down in the short run, because price is below average total cost. c. Continue to produce in the short run, because price is greater than average variable cost. d. Continue to produce in the short run, because firms are always stuck with having to produce in the short run.arrow_forwardWhich of the following indicates an extremely profitable market in the short-run? a.

- Would a firm earning zero economic profit continue to produce, even in the long run? In long-run competitive equilibrium, a firm earning zero economic profit A. will not continue to produce because this return is not covering its opportunity costs. B. will not continue to produce because it would be better off shutting down. C. will not continue to produce because such profit corresponds with negative accounting profit. D. will continue to produce because such profit is as high a return as could be earned elsewhere. E. will not continue to produce because it could earn a better return in another industry.arrow_forwardSuppose a perfectly competitive firm is breaking even (profit is equal to zero). In the short run, the firm should ________. In the long run it should ________. a.shut down; expand b.produce where MC = MR; keep the same production level c.shut down; exit the industry d.produce where MC = MR; leave the industryarrow_forwardPrice Average total cost AVC Demand Marginal cost Marginal revenue Q Quantity Discuss the firm plotted on the figure.

- Suppose a firm shuts down in the short run. Which of the following statements can you infer from the fact that the firm shuts down in the short run? a.The firm's losses are equal to its fixed costs. b.The firm would reopen in the long run. c.The firm's economic profits are zero. d.The firm's fixed costs are greater than its variable costs.arrow_forwarda perfectly competitive market over the long run, a. an increase in market demand or a decrease in firms' costs will lead to a decrease in the number of firms operating within the market. b. an improvement in production technology will increase profits at fust, but those profits will be competed away over time as more firms enter the industry and reduce market price. c. market price will equal maximum possible average total cost in long-run equilibrium. d. an increase in demand will cause the final market equilibrium to be at the original price but at a lower output level.arrow_forwardQ. In a perfectly competitive industry, a. Firms earn a breakeven profit in the short-run, but can either make an economic profit or make a loss in the long-run b. None of the above c. Firms can choose whether to produce or shut-down in the short-run d. Firms always charge a price equal to the minimum of AVC in the short-run e.
