Jan 11, 2019 · The long-run cost curves are u shaped for different reasons. It is due to economies of scale and diseconomies of scale . If a firm has high fixed costs, increasing output will lead to lower average costs.
The following article will guide you to know why cost curve is “U” shaped. The addition of fixed and Variable Cost gives us total costs, which when divided by the output give us Average Costs in the short period.
It is generally believed by economists that the long-run average cost curve is normally U shaped, that is, the long-run average cost curve first declines as output is increased and then beyond a certain point it rises.
The derivation of long run average costs is done from the short run average cost curves. In the short run, plant is fixed and each short run curve corresponds to a particular plant. The long run average costs curve is also called planning curve or envelope curve as it helps in making organizational plans for expanding production and achieving ...
Jul 17, 2023 · 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 .

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.
