Why Average Cost Curve is Shaped? (With Diagram)

This means three things: i The long run cost curve initially slopes downwards, i. The profits are high and maximised. Indeed the firm may produce so many related products that the brand name helps to advertise all of these different products. Thus the behaviour of the average total unit cost curve will depend upon the behaviour of the average variable cost and average fixed cost curve. For different scales of plant and sizes of firms different appropriate management techniques have been evolved and each management technique is applicable to a range of output. These are more difficult to identify but tend to be more managerial in nature.

Reading: Short Run and Long Run Average Total Costs

As a result of becoming bigger the firm which experiences internal economies of scale enjoys a situation where average costs per unit of production are falling as output is rising. These arise due to internal efficiency and are enjoyed by a particular firm and not by others belonging to an industry. Minimum Efficient ScaleThe long-run average cost curve is extremely important to the long-run production of a firm. Therefore the more you produce, the lower the average fixed costs will be. Diagram for Economies and Diseconomies of Scale Note, however, not all firms will experience diseconomies of scale.

Long Run Average Cost (LRAC)

short run average cost curve u shaped

Why average cost curve is 'u' shaped? Economies and diseconomies arise not only from the proportions of the factors but also from the scale of operations. This would lead to diseconomies of production and diminishing returns. In other words, the longer the period, the fewer cost will be fixed and more costs are variable. Overall because of diminishing marginal returns. There will be specia­lists on transport, personnel and administration. Article shared by : In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. When marginal cost is above the average cost then the average cost would be increasing.

This condition is satisfied only if the long-run average cost curve is tangential to the short- run average cost curves. The long-run is the period when full adjustment can be made. 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. What the empirical evidence does suggest is that technological progress may often be rapid enough to reduce unit cost even in a situation where, with given technology, the problem of managing a bigger firm would increase unit costs. Differences between short period and long period average costs: 1 Long period average cost denotes the costs of different plants. Due to the operation of the law of increasing returns the firm is able to work with the machines to their optimum capacity and as a consequence the Average Cost is minimum.

L} , where P K is the unit price of using physical capital per unit time, P L is the unit price of labor per unit time the wage rate , K is the quantity of physical capital used, and L is the quantity of labor used. Another group of economies referred to as external economies of scale are generated not as a result of the growth of the firm, but as a consequence of the concentration and growth of an industry within an area. 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. The Relationship between Average Cost and Marginal Cost : In Figure 7. The reason is that the cost curve falls on account of various economies of scale. This means that the largest firm tends to have a cost advantage, and the industry tends naturally to become a monopoly, and hence is called a natural monopoly.

Why short run average cost curve is U shaped

The same principles applies in relation to the cost curves in Fig. This triggers changes in and thus average cost variable and total. For relatively small quantities of output, the curve is negatively sloped. An introduction to positive economics fourth ed. The short-run and long-run total cost curves are increasing in the quantity of output produced, because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical capital input; and using more of either input involves incurring more input costs.

This curve is obtained by drawing a line which touches the series of possible short-run cost curves. In the long run, capacity can be varied, new machines can be ordered, the size of the factory can be altered, or new factories can be set up. Technical economies: i The large firm can introduce more division of labour and specialisation as it increases in size. To the right of the point of tangency the firm is using too little capital and diminishing returns to labor are causing costs to increase. It must slope downwards to the right because as output increases the average fixed cost diminishes. However, in industries that require heavy capital investment automobile plants, airlines, mines and have high average costs, it is comparatively very low. It may be, therefore, that technological change is not the only reason why long-run cost curves are L-shaped rather than U- shaped.

Thus marginal cost initially falls, reaches a minimum value and then increases. The long-run cost curve is the locus of equilibrium point on the short-run cost curves. Risk-bearing economies: Businesses are faced with many risks, e. The growth of component and other suppliers within the area. Average fixed cost continuously falls as production increases in the short run, because K is fixed in the short run. Explanation according to the diagram:- If the anticipated rate of output is 200 units per unit of time, the firm will choose the smallest plant. The additional output is simply the marginal product of the additional worker, 8.
