In the market for a product, there are 100 identical competitive firms, each firm having the cost function c(q) = 50 + 5q + 0.5 q^2 where q is the quantity of output in tons produced by each firm. The market demand curve is given by Q^d = 1660 - 20p. (a) Find the market equilibrium price p* and quantity produced by each firm q*. (b) A permanent increase in demand shifts the market demand to Q^d = 1920 -20 p. What will be the approximate price p** (up to two decimal places) in this market in the short run? (c) Given the permanent increase in demand, how man firms will there be in this market in the long run after entry or exit?
