Suppose that the dairy industry is initially in a completely competitive equilibrium. Suppose that, in the long run, the technology is such that average cost is constant at all levels of output. Suppose that producers agree to form an association and behave as a profit-maximizing monopolist. Describe clearly in a diagram the effects on (a) market price, (b) the equilibrium output, (c) the economic profit, (d) consumer surplus, and (e) the welfare loss.
