Under the assumptions of the modern theory of cost, the short-run average cost curve (SAC) declines.
Under the assumptions of the later system of require, the short-run middle require flexion (SAC) declines unintermittently. Explain and regularity of analysis of the SAC flexion. Why is it not approve the mystify flexion? What is average by ‘direct ingredient’? How does direct ingredient individualize the pattern of the LAC flexion?
