Which statements is TRUE for a perfectly competitive firm that is in long-run equilibrium?

Question

Quizplus · Accepted Answer

In long-run equilibrium, a perfectly competitive firm produces where price equals marginal cost (P=MC), and this point coincides with the minimum of the long-run average total cost (LRATC) curve. Since the firm can adjust all inputs in the long run, the SRATC (short-run average total cost) curve relevant to the equilibrium output will also be tangent to the LRATC at its minimum point, meaning the firm is operating at the minimum point of both its LRATC and SRATC curves.
