- The industry in the figure below consists of many firms with identical cost structures, and the industry experiences constant scale. Consider a change in demand from D₁ to D2, which increases price from $20 to $30 in the short run. Price $50 $40 $30 $20 $10 0 10 20 Market 30 D₁ 40 Quantity S₁ D₂ 50 60 70 Tools LRS O S₂ Instructions: Enter your answers as a whole number. a. Draw the new short-run market supply curve that will occur in response to the increase in demand and increase in price. Instructions: Use the tool provided 'S2' and be sure your supply curve includes the new equilibrium price and quantity. b. Draw the long-run supply curve. Instructions: Use the tool provided 'LRS' and plot only the endpoints over the entire range of output (0-60). The new equilibrium price is $ 20 and the new equilibrium quantity is 40.arrow_forwardWhat does it mean to be operating a firm in the "long run?"

- Brody's firm produces trumpets in a perfectly competitive market. The table below shows Brody's total variable cost. He has a fixed cost of $240, and the price per trumpet is $60.-Calculate the average total cost of producing 6 trumpets. Show your work. -Calculate the marginal cost of producing the 11th trumpet. -What is Brody's profit-maximizing quantity? Use marginal analysis to explain your answer. -At the profit-maximizing quantity you determined in part (c), calculate Brody's profit or loss. Show your work. -Brody also produces saxophones at a loss in a perfectly competitive market. Draw a correctly labeled graph for Brody's firm showing the following at a market price of $200. -Brody's profit-maximizing quantity of saxophones -Brody's loss, completely shaded Quantity Total Variable cost 6 $120 7 $145 8 $165 9 $220 10 $290 11 $390arrow_forwardThe owner of Tie-Dyed T-shirts, a perfectly competitive firm, hires you to give him economic advice. He tells you that the market price for his shirts is $15 and that he is currently producing 200 shirts at an AVC of $10 and an ATC of $20. What would you recommend that he do? O a. Tell him that you cannot make any recommendations until you know what his fixed costs are. O b. Continue producing in the short run, as his loss from production is less than his fixed costs, but exit the industry in the long run if there are no changes in economic conditions. Oc Shut down in the short run, as he is incurring a loss, and leave the industry in the long run, if there are no changes in economic conditions. O d. Continue to produce in the short run, even though he is earning a loss, and expand production in the future hoping to increase market share and total revenue.arrow_forwardWhat will happen when variable costs rise in a perfectly competitive industry?
