As expected, short-run average cost (SRAC} curves for the larger plants are positioned to the right of the curves for smaller ones, indicating greater production capacity. For example, SRAC B is to the right of SRAC A because plant B is larger than plant A. But. as noted in Figure 7.9, plants with larger capacities are greatly influenced by economies and diseconomies of scale. Because of the impact of economies of scale, plant B's SRAC curve is positioned below and to the right of plant A's, so the minimum point of B’s SRAC curve is flower than that for A. The same can be said for plant C's minimum SRAC in relation to plant B’s and for D's in relation to C's. However, because of the impact of diseconomies of scale, plant E's SRAC curve is positioned above and to the right of D’s, and plant F’s is above and to the right of E's. That is, the SRAC curves of plants larger than plant D have progressively higher minimum average cost points. For reference, the minimum SRAC points for all the plants are marked in Figure 'F.9 with asterisks.
