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. In the short run, the expansion is done by hiring more labor and increasing capital. A replacement cost is the price that would have to be paid currently to replace the same asset. In this situation, any firm with a level of output between 5,000 and 20,000 will be able to produce at about the same level of average cost. 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. One prominent example of economies of scale occurs in the chemical industry. The average cost is obtained by dividing the total variable cost with the total output.
The use of greater degree of division of labour and the specialised machinery at higher levels of output are called the internal economies. This second explanation, based on the insight that a single firm may own a number of different manufacturing plants, is especially useful in explaining why the long-run average cost curve often has a large flat segment—and thus why a seemingly smaller firm may be able to compete quite well with a larger firm. The two normal implicit costs are depreciation, interest on capital etc. The calculations in show that a pipe which uses twice as much material to make as shown by the circumference of the pipe doubling can actually carry four times the volume of chemicals because the cross-section area of the pipe rises by a factor of four as shown in the Area column. This factor might seem to predict a future with a larger number of small competitors. With the rise in the volume of production total cost rises. In the long run, even the fixed cost becomes the variable cost as the size of the firm or scale of production increases.
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. As opposed, the factor proportion remains same in the long run production function, as all factor inputs vary in the same proportion. Amazon has no retail locations; it sells online and delivers by mail. The Growth of Subsidiary and Correlated Industries: Another external economy accruing to the firms from the growth of an industry is the growth of subsidiary and correlated industries. After all, lower costs lead to higher profits—at least if total revenues remain unchanged.
The leviathan effect can hit firms that become too large to run efficiently, across the entirety of the enterprise. Thus, it is a U- shaped curve, as shown in Figure-7: vi. For example cost of the ideal machine capacity is unavoidable cost. Interest rate spreads on new loans are rising and it is larger firms that seem to be benefitting from lower borrowing costs. Moreover, when we are considering the effect of external economies and external diseconomies on the cost curves, it is not only the long-run average cost curve but all short-run and long-run cost curves, whether total, average or marginal, shift together up or down as the case may be.

These new technologies create the possibility for smaller companies or plants to generate electricity as efficiently as large ones. In this case, a firm producing at a quantity of 10,000 will produce at a lower average cost than a firm producing, say, 5,000 or 20,000 units. The accounting concept is a historical concept and records what has happened in the post.
This makes it possible to produce them on a large scale by other industries. At higher levels of output, the firm may find that its output increases at the same rate at which it increases its factor inputs. External economies accrue to the individual firms, if the increase in the output of industry lowers the cost curves of each firm in the industry. How can cities be viewed as examples of economies of scale? An example might be a large number of hotels in a city centre or a cluster of restaurants in a town. It can operate at various activity levels because the firm can change and adjust all the factors of production and level of output produced according to the business environment. The shape of the long-run cost curve, as drawn in , is fairly common for many industries. Types of External Economies: Now, the question arises when an industry grows or expands its output, what types of external economies it generates which reduce the costs of the firms in it.
This, of course, will happen in cases where there are increasing returns i. Like Marshall, Joan Robinson who analysed the phenomenon of increasing returns i. In short run, the plant sizes are fixed thus, organization increase or decrease the variable factors. The relationship between the quantity at the minimum of the long-run average cost curve and the quantity demanded in the market at that price will predict how much competition is likely to exist in the market. Finally, the right-hand portion of the long-run average cost curve, running from output level Q 4 to Q 5, shows a situation where, as the level of output and the scale rises, average costs rise as well. Other controversial examples of the use of monopsony power include the in some of the poorest parts of the world. They also provide a large group of workers and suppliers, so that business can hire easily and purchase whatever specialized inputs they need.
These costs are incurred on the fixed factors, Viz. The left-hand portion of the long-run average cost curve, where it is downward- sloping from output levels Q 1 to Q 2 to Q 3, illustrates the case of economies of scale. These subsidiary and correlated industries may specialise in the production of raw materials, tools and machinery and therefore can provide them at lower prices to the main industry. They lead to lower prices and higher — this is called a positive sum game for producers and consumers i. This situation is called diseconomies of scale. This concept is very important in capital expenditure budgeting.
Opportunity cost is the cost concept to use when the supply of inputs is strictly limited and when there is an alternative. The concept is also useful for taking short-run decisions. For example, traffic congestion may reach a point where the gains from being geographically nearby are counterbalanced by how long it takes to travel. Please do send us the Long Run average Cost Curve problems on which you need help and we will forward then to our tutors for review. . As total fixed cost is unchanged, the rise in total cost is brought about by the rise in total variable cost.
