Gооd Z is prоduced аnd sold in а competitive industry, аnd long-run industry supply is characterized by constant costs. The figure below shows a typical long-run average cost curve (LAC) for each of the firms producing good Z. LAC reaches its minimum unit cost of $12 and 1,000 units of output (point M). Suppose the demand for good Z is Qd = 52,000 - 1,000P.In long-run competitive equilibrium, each firm’s long-run marginal cost (LMC) is $_________ and each firm’s long-run average cost (LAC) is $_________.
