Explain. When does a profit-maximizing competitive firm decide to shut down? When does it decide to exit a market?3QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR8QR1PA2PA3PA4PA5PAA firm in a competitive market receives 500 in total revenue and has marginal revenue of 10. What is the average revenue, and how many units were sold?7PA8PA9PA10PASuppose that each firm in a competitive industry has the following costs: Total cost: TC = 50 + q2 Marginal cost: MC = q where q is an individual firms quantity produced. The market demand curve for this product is Demand:QD = 120 P where P is the price and Q is the total quantity of the good. Currently, there are 9 firms in the market. a. What is each firms fixed cost? What is its variable cost? Give the equation for average total cost. b. Graph average-total-cost curve and the marginal-cost curve for q from 5 to 15. At what quantity is average-total-cost curve at its minimum? What is marginal cost and average total cost at that quantity? c Give the equation for each firms supply curve. d. Give the equation for the market supply curve for the short run in which the number of firms is fixed. e. What is the equilibrium price and quantity for this market in the short run? f. In this equilibrium, how much does each firm produce? Calculate each firms profit or loss. Is there incentive for firms to enter or exit? g. In the long run with free entry and exit, what is the equilibrium price and quantity in this market? h. In this long-run equilibrium, how much does each firm produce? How many firms are in the market?1QQ2QQ3QQ4QQ5QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR8QR1PA2PA3PA4PA5PA6PA7PA8PA9PA10PA11PA12PA1QQ2QQ3QQ1CQQ2CQQ3CQQ4CQQ5CQQIf advertising makes consumers more loyal to particular brands, it could __________ the elasticity of demand and ____________ the markup of price over marginal cost. a. increase, increase b. increase, decrease c. decrease, increase d. decrease, decrease1QR2QR3QR4QRHow might advertising reduce economic well-being? How might advertising increase economic well-being?6QR7QR1PA2PA3PA4PA5PA6PA7PA8PA9PASleek Sneakers Co. is one of many firms in the market for shoes. a. Assume that Sleek is currently earning short-run economic profit. On a correctly labeled diagram, show Sleek's profit-maximizing output and price, as well as the area representing profit. b. What happens to Sleek's price, output, and profit in the long run? Explain this change in words, and show it on a new diagram. c. Suppose that over time consumers become more focused on stylistic differences among shoe brands. How would this change in attitudes affect each firm's price elasticity of demand? In the long run, how will this change in demand affect Sleek's price, output, and profit? d. At the profit-maximizing price you identified in part (c), is Sleek's demand curve elastic or inelastic?

Lets analyze the game between the two companies. Suppose that each company can charge either a high price for tickets or a low price. If one company charges 300, it cams low profit if the other company also charges 300 and high profit if the other company charges 600. On the other hand, if the company charges 600, it cams very low profit if the other company charges 300 and medium profit if the other company also charges 600. a. Draw the decision box for this game. b. What is the Nash equilibrium in this game? Explain. c. Is there an outcome that would be better than the Nash equilibrium for both airlines? How could it be achieved? Who would lose if it were achieved?8PA9PA1QQ2QQ3QQ4QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR1PA2PA3PA4PA5PA6PA7PA8PA9PA1QQ2QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR8QR1PA2PA3PA4PA5PA6PA7PA8PA1QQ2QQ3QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR1PA2PA3PA4PA5PA6PA7PA8PA1QQ2QQ3QQ4QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR1PA2PA3PA4PA5PA6PA7PA8PA9PA10PA11PA12PA1QQ2QQ3QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR1PA2PA3PA4PA5PA6PA7PA8PA9PA10PA1QQ2QQ3QQ4QQ5QQ1CQQ2CQQ3CQQ4CQQ5CQQ6CQQ1QR2QR3QR4QR5QR6QR7QR8QR1PA2PA3PA4PA5PA6PA7PA9PA10PA
