    The long run average cost curve for a firm describes how its costs change when all of the factors of production which it employs to make its products are allowed time to vary. This is the key distinction between the long run and the short run i.e., in the short run only labor is allowed to vary because only workers can be recruited or released ...

    Given the total cost curves in Figure 13, short-run average cost will be equal to long-run average cost only at an output of Q 0. (Since LRAC=LRTC is equal to SRTC). At any other level of output, short-run average cost is higher than long-run average cost, because SRTC is greater than LRTC.

    The long-run average cost (LRAC) curve shows the firm’s lowest cost per unit at each level of output, assuming that all factors of production are variable. The LRAC curve assumes that the firm has chosen the optimal factor mix, as described in the previous section, for producing any level of output.

    • Choice of Production Technology. A firm can perform many tasks with a range of combinations of labor and physical capital. For example, a firm can have human beings answering phones and taking messages, or it can invest in an automated voicemail system.
    • Economies of Scale. Once a firm has determined the least costly production technology, it can consider the optimal scale of production, or quantity of output to produce.
    • Shapes of Long-Run Average Cost Curves. While in the short run firms are limited to operating on a single average cost curve (corresponding to the level of fixed costs they have chosen), in the long run when all costs are variable, they can choose to operate on any average cost curve.
    • The Size and Number of Firms in an Industry. The shape of the long-run average cost curve has implications for how many firms will compete in an industry, and whether the firms in an industry have many different sizes, or tend to be the same size.

    The long-run average cost (LRAC) curve shows the lowest cost for producing each quantity of output when fixed costs can vary, and so it is formed by the bottom edge of the family of SRAC curves. If a firm wished to produce quantity Q 3 , it would choose the fixed costs associated with SRAC 3 .

    Jul 23, 2023 · The long-run average cost at a production rate of 2000 units per production period is the lowest cost for average cost curve SRAC 2 (which has a capacity of 2000). The long-run average cost at a production rate of 3000 units per production would be the average cost at capacity for SRAC 3.
