hdavid57 | Does minimum efficient scale occur at the point where economy of scale and constant returns to scale meet? |
rfvo | True...........The minimum efficient scale (MES) is the output for a business in the long run where the intern. al economies of scale have been fully exploited. It corresponds to the lowest point on the long run average total cost curve and is also known as the output of long run productive efficiency. |
