Suppose that introductory chemistry books are produced in a constant cost perfectly competitive industry. All firms face the same long-run average cost curve which has its minimum point at the same level of output and average cost as in the short-run. The demand for economics textbooks is: P = 170 - 0.03Q In the initial long-run equilibrium, there are 200 firms in the industry, producing a total of 4000 units of output. Fixed costs in the short-run are $300. The short-run total cost curve of each firm is given by: TC = 400 + 10q + q? Below what price will this firm shut down in the short-run? Below what price will this firm shut down in the long-run? Now, the government imposes a production tax of $86 per textbook. What is the buyer's share (in percent) of this $86 tax in the short-run? What is the buyer's share (in percent) of this $86 tax in the long-run? Note: Enter your figures with TWO decimal places and NO other symbols (except a ". and 6.5 percent is written simply as 6.50
