Suppose that each firm in a competitive industry has the following costs: Totalcost:TC=50+1/2q2 Marginalcost:MC=q where q is an individual firm's 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. 1. Give the equation for the market supply curve for the short run in which the number of firms is fixed. 2. What is the equilibrium price and quantity for this market in the short run? 3. In this equilibrium, how much does each firm produce? Calculate each firm's profit or loss. Is there incentive for firms to enter or exit?

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

Suppose that purely competitive firms producing cashews discover that P exceeds MC. Is their combined output of cashews too little, too much, or just right to achieve allocative efficiency? In the long run, what will happen to the supply of cashews and the price of cashews? Use a supply and demand diagram to show how that response will change the combined amount of consumer surplus and producer surplus in the market for cashews.
