Shazam, a maker of magic wands, is selling in a purely competitive market. Its output is 600 wands, which sell for $8 each. At this level of output, the marginal cost is $8, average total cost is $20 and the average variable cost is $12. Should the firm increase output, decrease output, or not produce and shut-down? Why?

Which of the following statements is correct? 8 Price, P (€); cost 4 3.70 2.50 2 0 0 Select one: 20 40 60 80 100 120 140 Quantity of loaves, Q 160 180 O a. The bakery is a price setter and sets its price as 2.50. b. The bakery maximises its profits by supplying 160 loaves. O c. The bakery's profit is 200. Marginal cost curve Isoprofit curve: €200 Isoprofit curve: €80 Firm's demand curve Zero-economic- profit curve (AC curve) 200 O d. The bakery's profit decreases until the quantity is 120, and then increases. e. The marginal cost curve is the bakery's supply curve.
Converse has been fairly successful selling denim colored UK sportswear. Lydia, wanting to get in on the profit, has also entered this market. After producing her profit maximizing level of output she finds that her average total cost per unit is $40, her average variable cost per unit is $30, and her selling price (forced upon her by the market), is $20. In the short run, she should: O go back to college and shut down her denim UK sportswear business. Ostay in business even though she is suffering a loss. O expand production since she is making a positive economic profit. O burn down the Converse factory so she can capture their share of the market and make even bigger profits than the profit she is already making.

Price R W S 0 A F H B G MC K ATC AVC MR Quantity Assuming that price at OR is $10, the profit maximizing level of output for the firm is 1. OA where marginal cost just covers AVC 2. OB where average profit per unit is the greatest 3. OC where marginal cost equals the $10 price 4. OK where average cost equals marginal revenue and the firm earns a normal rate of return
The following graph plots the marginal cost (MC) curve, average total cost (ATC) curve, and average variable cost (AVC) curve for a firm operating in the competitive market for snapback hats. COSTS (Dollars) 100 100 80 90 80 20 70 70 HD 50 40 30 20 0 11 D 10 O MC Price (Dollars per snapback) 15 15 20 25 55 70 85 201 ATC 0 D AVC O 50 60 70 80 QUANTITY (Thousands of snapbacks) For every price level given in the following table, use the graph to determine the profit-maximizing quantity of snapbacks for the firm. Further, select whether the firm will choose to produce, shut down, or be indifferent between the two in the short run. (Assume that when price exactly equals average variable cost, the firm is indifferent between producing zero snapbacks and the profit-maximizing quantity of snapbacks.) Lastly, determine whether the firm will earn a profit, incur a loss, or break even at each price. □ Quantity (Snapbacks) BO 100 ▼ On the following graph, use the orange points (square symbol) to…
Figure 14-13 Suppose a firm in a competitive industry has the following cost curves: 10 9- 8 7. 6 اکیه 3.5 2 1- Price 1 2 3 4 MC 5 6 7 8 ATC AVC Refer to Figure 14-13. If the price is $2 in the short run, what will happen in the long run? ◆a. Individual firms will earn positive economic profits in the short run, which will entice other firms to enter the industry. b. Nothing. The price is consistent with zero economic profits, so there is no incentive for firms to enter or exit the industry. ● C. Individual firms will earn negative economic profits in the short run, which will cause some firms to exit the industry. d. Because the price is below the firm's average variable costs, the firms will shut down. 45
