A firm produces a product in a perfectly competitive industry and has a total cost function
TC= 50+4q+2q².
a. At the short-run market price of $20, the firm is producing 5 units of output. Is the firm
maximizing its profit? Explain.
b. What quantity of output will the firm produce in the long run, assuming there is no change in
cost structure? What will be the long-run equilibrium price?
c. Graphically depict the long-run equilibrium for an individual firm within this market.
In a perfectly competitive market, each firm has the cost function: q 2+10q+100. The price in the market is $50.
a. What is the Marginal Cost for the firm?
b. What is the Profit Maximizing Output?
c. What is the Total Profit the firm receives?
d. Should this firm continue to produce in the short run? Please explain.
e. If the price is $20, should the firm continue to produce? Please explain.
Assume a constant price for a perfectly competitive firm operating in the short-run. If higher labor costs
increase the firm's marginal cost of production, the firm would decrease its profit-maximizing level of
output, ceteris paribus. True or False.
A. True
B. False

- 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_forwardDraw the short-run ATC, AVC, MC, MR and Demand graphs for a perfectly competitive market experiencing a profit.

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_forward

- Assume the industry for flour tortillas in Denver is perfectly competitive. There are 200 firms. Seventy-five of the firms are “high-cost,” with short-run supply curves QHC = 5P. The other 125 are “low-cost,” with short-run supply curves QLC = 8P. Quantities are measured in dozens of tortillas and prices in dollars. Derive the short-run industry supply curve for tortillas QS. Assume the market demand curve for tortillas is given by QD = 10,000 − 625P. Find the market equilibrium price and quantity. At this price, how many dozens of tortillas are produced by the high- and low-cost firms, respectively? Determine total industry producer surplus at the equilibrium.

- a.Suppose a perfectly competitive firm can produce10000 bushels of corn a year at an output at which marginal revenue is equal to marginal cost. The market price of corn per bushel is $2. The firm's total costs per year are $30000 and fixed costs per year are $15000. Show and explain which of the following is true: In the short run, this firm should a) Produce 20000 bushels to try to increase economic profit. b) Produce 10000 bushels of corn because, although they are losing money, they are losing less than if they shut down. c)Shut down. d) Continue producing until the price of corn increases. b.A perfectly competitive firm, with MC=q operates in a market character,zed by the following market demand and supply conditions: Demand: Q=20000-100P Supply: Q=100P How much output does this competitive firm produce to maximize profit?
