The demand for a product is Q = 100

  1. P. Initially the marginal cost is MC0 = 40 and the price is P0 = 40.

(a) What is the total surplus and If a cartel forms, the price rises to P1 = 70, and the marginal cost stays the same at MC1 = 40. What is the total surplus with a cartel?

(b) If a merger happens, the price would become P2 = 70 and the marginal cost would become MC2 = 30. What is the total surplus after the merger?

(c) Consider again the merger. Keeping all the others parameters fifixed, for what values of P2 should the merger be allowed? (Your can say something like “the merger should be allowed if P2 is more than 50”, or “the merger should be allowed if P2 is less than 50”.)
