Apr 29, 2024 · Long-Run Average Cost (LRAC) is an economic concept that describes the average cost per unit of output that a firm can achieve when it adjusts all of its inputs in the long run. In other words, LRAC represents the cost per unit at which a firm can produce any given level of output when it is free to vary all its inputs, such as labor and capital, and achieve the most efficient scale of operation.
Figure 8.9 Relationship Between Short-Run and Long-Run Average Total Costs. The LRAC curve is found by taking the lowest average total cost curve at each level of output. . Here, average total cost curves for quantities of capital of 20, 30, 40, and 50 units are shown for the Lifetime Disc
The long run marginal cost (LRMC) curve relates to the LRAC curve in exactly the same way that short run marginal cost relates to a short run average cost curve. Marginal cost means the cost of producing the last unit of output, so whenever average cost is falling it follows that marginal cost must be lower than average cost, and vice versa ...
A long run average cost curve is known as a planning curve. This is because a firm plans to produce an output in the long run by choosing a plant on the long run average cost curve corresponding to the output. It helps the firm decide the size of the plant for producing the desired output at the least possible cost.
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 .

Apr 12, 2021 · Long run average cost is the cost per unit of output feasible when all factors of production are variable. In the long run, all costs are assumed to be variable. Economies of scale are the unit cost advantages from expanding the scale of production in the long run. The effect is to reduce average costs over a range of output.
