Consider the market for solar power. Assume the market is perfectly competitive and initially in long-run equilibrium; solar power sells for $.25 per kwh (kilowatt hour, a unit of power). What happens to the market and the firm in the long run? Indicate clearly what happens to price, quantity, and profit, for each the market and the firm.
The figure below shows the supply and the demand for a good (left) and the cost curves of an individual firm in this market (right). Assume that all firms in this market, including the potential entrants, have identical cost curves. Initially, the market is in equilibrium at point A. Price Cost MC ATC A 4 2 1 D 2 4 6 8 10 12 Quantity Quantity Refer to the figure above. Suppose that the market has reached the long-run equilibrium. Then, due to news of the product's defects and recall, the demand falls by 4 units at each price. At the new equilibrium, each firm in the market earns and there will be a. zero economic profit; neither entry nor exit of firms b. positive economic profit; entries of new firms C. zero accounting profit; both entry and exit of firms d. negative economic profit; exit of existing firms
The following problem traces the relationship between firm decisions, market supply, and market equilibrium in a perfectly competitive market. a. Complete the following table for a single firm in the short run. Using the information in the table, fill in the following supply schedule for this individual firm under perfect competition and indicate profit (positive or negative) at each output level. (Hint: At each hypothetical price, what is the MR of producing 1 more unit of output? Combine this with the MC of another unit to figure out the quantity supplied.)
(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).
