Exercise 2.9 Firms in a competitive industry have production costs C(q) =q²+20q+100 and the industry demand is QD(P)=1200-10P; a) Find the price, the production of the representative company, the production of the industry and the number of companies that will be part of the industry it in the long-term equilibrium. b) Suppose that demand shifts to QD(P) = 1.800 - 12P. Find the price, quantity and profits of companies in the short term. Calculate the social welfare corresponding to this equilibrium. (c) Calculate the final long-term equilibrium. Describe the adjustment process in a graph.

Feedback Imagine that the flat-screen TV market is made up of one large firm that leads the industry and sets its own price first, and another firm that follows the leader when deciding its own profit-maximizing strategy. The leader has a cost function of c₁ (91) = 5q1, and the follower has a cost function of CF (ar) = 4, where Q =q₁ + qr. Total market demand for flat-screen TVs is given by the function Q = 250.00-2p. Calculate the following values: Leading firm's production: q = Follower firm's production: qp = Equilibrium price: p= $49.37 9 OF 16 QUESTIONS COMPLETED 118.33 32.92 (Round to two decimals if necessary.)

Suppose that a factory that enjoys a monopoly in their market has one of their senior engineers retire. Losing this engineer caused the marginal and average total costs to increase by $20. As a result of this rise in costs, the factory changes its price to continue to maximize profit. We should expect production to: Select an answer and submit.
