These firms ended up having to finance their own police and fire fighters, take medical care into consideration, and other things the firm wasn't really good at doing. At some point, however, the task of coordinating and managing many different plants raises the cost of production sharply, and the long-run average cost curve slopes up as a result. As organisations grow they may involve production at several separate plants, and the co-ordination of activities becomes less effective. Firms in the market are producing output, but they are currently making economic losses. High densities of people, cars, and factories can mean more garbage and air and water pollution. On the other hand the long-run is the period during which all types of adjustments can be made to meet the changed demand because all the factors can be varied. These arise due to internal efficiency and are enjoyed by a particular firm and not by others belonging to an industry.

Why is the long run average cost curve “U” shaped?

long run average cost curves are u shaped because

Refer to the above data. Refer to the above data. Many industries experience economies of scale. The law of variable proportions will apply and diminishing returns or increasing costs will begin to operate. This is not profitable for the firm.

In other words, the cost of each additional unit of output is falling as output expands. A firm or a factory can grow so large that it becomes very difficult to manage, resulting in unnecessarily high costs as many layers of management try to communicate with workers and with each other, and as failures to communicate lead to disruptions in the flow of work and materials. For example, a firm can have human beings answering phones and taking messages, or it can invest in an automated voicemail system. In this case, any firm producing a quantity between 5,000 and 20,000 can compete effectively, although firms producing less than 5,000 or more than 20,000 would face higher average costs and be unable to compete. This curve is constructed to capture the relation between marginal cost and the level of output, holding other variables, like technology and resource prices, constant. It slopes downwards initially and then rises upwards.

After all, lower costs lead to higher profits—at least if total revenues remain unchanged. The traditional coal-burning electricity plants needed to produce 300 to 600 megawatts of power to exploit economies of scale fully. In , a cost curve is a graph of the as a function of total quantity produced. In such a case, the optimum size of the firm is indeterminate, since all levels of output can be produced at the same long-run average cost which represents the same minimum short- run average cost throughout. A firm learns to produce a commodity more efficiently as the aggregate amount of its output produced by it increases over time. There will be specia­lists on transport, personnel and administration.

Long Run Average Cost (LRAC)

long run average cost curves are u shaped because

In the , when at least one factor of production is fixed, this occurs at the output level where it has enjoyed all possible average cost gains from increasing production. The firm's short-run supply curve is: A. By the long period, we mean the period during which the size of the firm can be altered. A above; decreasing B below; decreasing C above; increasing D below; increasing 37 If production displays economies of scale, the long-run average cost curve is A above the short-run average total cost curve. Suppose he alters his scale so that his new cost curve is U 3. E units and charge price A. In the long run, firms can choose their production technology, and so all costs become variable costs.

For each of these scales there is an optimum output. Consider the example of a private firm that is hired by local governments to clean up public parks. This pattern was illustrated earlier in. Refer to the above data. There may be economies of scale for negative activities like crime, because high densities of people and businesses, combined with the greater impersonality of cities, make it easier for illegal activities as well as legal ones.

This is because there are economies of scale that have not been exploited so in the long run a firm could always produce a quantity at a price lower than minimum short run average cost simply by using a larger plant. Eventually production costs short run average cost curvesaverage fixed afc a. Thus, the market for dishwashers will consist of 100 different manufacturing plants of this same size. Since short-run fixed cost does not vary with the level of output, its curve is horizontal as shown here. The concept of economies of scale, where average costs decline as production expands, might seem to conflict with the idea of diminishing marginal returns, where marginal costs rise as production expands.

But the shape of the long-run average cost curve depends upon the returns to scale. B average variable cost is decreasing. Long-run average total costs curves are often U-shaped: A: For the same reasons that average total cost curces are often U-shaped. The marginal cost of producing the sixth unit of output is: A. Why Long-run average cost curve is flatter Long-run average cost curve is flatter in terms of fixed costs and variable costs.

Refer to the above diagram for a purely competitive producer. If we connect different short run average cost curves by drawing line, we get the long run Average cost curve. Diseconomies of scale occur when an equal percentage increase in all factors of production results in a lower percent increase in output -- eg. Refer to the above data. In the middle portion of the long-run average cost curve, the flat portion of the curve around Q 3, economies of scale have been exhausted. The first production technology is heavy on workers and light on machines, while the next two technologies substitute machines for workers.

We can also write total output, Q, as the average product, 10, multiplied by the number of workers, four. Here total product is, respectively, 32 and 40 units. How do economies of scale compare to diminishing marginal returns? More precisely, the long-run average cost curve will be the least expensive average cost curve for any level of output. Generally speaking, the shape of the curve depends on the relative importance of the fixed and the variable costs of production and the degree of sharpness with which the law of diminishing returns is operative for the variable factors. In the short run extra output can be produced by a firm by utilising its existing capacity i.
