- (a) Let the industry producing soybeans be in a long-run equilibrium. What is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel of soybeans? (b) Suppose that the demand for soybeans drops due to decreased im- port by China and becomes Q = 15.3 − p. In a new long run equilibrium, what is the equilibrium price of a bushel of soybeans? How many billions of bushels are produced? How many farmers are there in the industry? What is the shipping fee per bushel? (c) Calculate the change in the producers’ surplus between the situations described in (a) and (b). (d) Show that the decrease in the producers’ surplus equals to the decrease in the total shipping fees as the industry contracts incrementally from the equilibrium output in (a) to the equilibrium output in (b).The following problem traces the relationship between firm decisions, market supply, and market equilibrium in a perfectly competitive market. a.

Calculate the equilibrium price in the very short run. b. Calculate the demand schedule facing any one firm in this industry. c. Calculate what the equilibrium price would be if one of the sellers decided to sell nothing or if one seller decided to sell 200 units. d. At the original equilibrium point, calculate the elasticity of the industry demand curve and the elasticity of the demand curve facing any one seller. Suppose now that, in the short run, each firm has a supply curve that shows the quantity the firm will supply (q) as a function of market price. The specific form of this supply curve is given by 9-200+50P. Using this short-run supply response, supply revised answers to (a)-(d). 11A 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.
