In domestic utilities with high fixed costs of providing the supply network, the average cost of producing a unit of water, electricity, or gas will be very high unless the firm operates at a large scale. If a single firm can supply the whole market at lower average cost than two firms, the industry is said to be a natural monopoly.
The long-run average cost curve shows the cost of producing each quantity in the long run, when the firm can choose its level of fixed costs and thus choose which short-run average costs it desires. If the firm plans to produce in the long run at an output of Q 3 , it should make the set of investments that will lead it to locate on SRAC 3 , which allows producing q 3 at the lowest cost.

- Economic Versus Accounting Concepts of Profit and Loss. Economic profit equals total revenue minus total cost, where cost is measured in the economic sense as opportunity cost.
- The Long Run and Zero Economic Profits. Given our definition of economic profits, we can easily see why, in perfect competition, they must always equal zero in the long run.
- Eliminating Economic Profit: The Role of Entry. The process through which entry will eliminate economic profits in the long run is illustrated in Figure 9.14 “Eliminating Economic Profits in the Long Run”, which is based on the situation presented in Figure 9.7 “Applying the Marginal Decision Rule”.
- Eliminating Losses: The Role of Exit. Just as entry eliminates economic profits in the long run, exit eliminates economic losses. In Figure 9.15 “Eliminating Economic Losses in the Long Run”, Panel (a) shows the case of an industry in which the market price P1 is below ATC.
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. Thus, the long-run average cost (LRAC) curve is actually based on a group of short-run average cost ...
However, if the long-run average cost curve has a wide flat bottom like Figure 3 (b), then firms of a variety of different sizes will be able to compete with each other. The flat section of the long-run average cost curve in Figure 3 (b) can be interpreted in two different ways. One interpretation is that a single manufacturing plant producing ...
Jan 11, 2019 · Diagrams of Cost Curves. 11 January 2019 by Tejvan Pettinger. Total Fixed Cost (TFC) – costs independent of output, e.g. paying for factory. Marginal cost (MC) – the cost of producing an extra unit of output. Total variable cost (TVC) = cost involved in producing more units, which in this case is the cost of employing workers.

In the long run the firm can examine the average total cost curves associated with varying levels of capital. Four possible short-run average total cost curves for Lifetime Disc are shown in Figure 8.14 “Relationship Between Short-Run and Long-Run Average Total Costs” for quantities of capital of 20, 30, 40, and 50 units.
