The raspberry growing industry is a perfectly competitive industry. The firms in the industry have a U-shaped LAC, minimum average cost is $8 and the minimum efficient scale is 4 units of X. The market demand curve is given by Q = 48-P.
a. Determine the long-run equilibrium price, quantity per firm, market quantity and number of firms. What profit does each firm earn in long-run?
b. Suppose that the government imposes a per-unit tax of $2 on the firms in the industry. Analyze the long-run effects of the policy. Draw a two part diagram (one for the typical firm and one for the market) to show the long-run effect of the policy on the industry.
c. Instead of a per-unit tax above, suppose that the government is considering of imposing a lump-sum tax. What would the effect of the lump-sum tax be on the long-run equilibrium price? Will firms enter or exit the industry?
