Consider the total cost and revenue curves shown below, for two perfectly competitive firms, Firm A and Firm B.

Short description: Two graphs labeled firm A and firm B. Long description: In each graph, the horizontal axis represents the quantity and the vertical axis represents dollars. The first graph representing firm A shows two increasing S-shaped parallel curves representing TC and TVC and an increasing line representing TR. TVC and TR begin at the origin. TC begins at a point, a little above the origin on the vertical axis. The second graph representing firm B shows two increasing S-shaped parallel curves representing TC and TVC and an increasing line representing TR. TVC and TR begin at the origin. TC begins at a point, a little above the origin on the vertical axis. TR intersects TC and TVC at two points, each.

FIGURE 9-5

Refer to Figure 9-5. If both Firms A and B are producing a level of output such that the slope of the TC curve is equal to the slope of the TR curve,



▸ then the ATC is at a minimum and both firms are maximizing profits.

▸ then both firms are earning positive economic profits because the distance between TR and TC is the greatest.

▸ then both firms are suffering losses because the distance between TR and TC is the smallest.

▸ then MC = MR, but both firms may not be maximizing their profits.

▸ then MC = MR and both firms are maximizing profit (or minimizing losses).
