Costs of production

why is the average total cost curve u shaped

Eventually, the cost begins to rise again as increase. The long-run marginal cost curve tends to be flatter than its short-run counterpart due to increased input flexibility as to cost minimization. The fact that technology changes does not in itself contradict our convention that, if only because it is harder to manage a larger firm than a smaller one, long-run average cost curves will be U-shaped in a given state of technology. It is because of the increasing returns to scale in the beginning that the long-run average cost of production falls as output is increased and, likewise, it is because of the decreasing returns to scale that the long-run average cost of production rises beyond a certain point. Thus, again, they are able to spread their risks. Large firms are better able to bear such a risk of decline in demand for a particular product because they will probably have diversified their output. We have stated above that according to empirical evidence long-run average cost after the initial rapid fall, either remains constant or declines throughout; it does not rise.

The empirical investigations which are based on times series data would not find the rising average cost in view of the existence of technological progress. According to him, perfect divisibility has nothing to do with efficiency, that is to say, perfect divisibility does not mean the absence of internal economies of scale. It must slope downwards to the right because as output increases the average fixed cost diminishes. External economies of scale: These are the economies which apply to the industry as a whole and each particular firm can enjoy these economies as the industry expands. As organisations grow they may involve production at several separate plants, and the co-ordination of activities becomes less effective. More intensive utilisation of the fixed equipment must necessarily lead to diminishing returns. As noted above, beyond a certain point the long-run average cost curve rises which means that the long-run average cost increases as output exceeds beyond a certain point.

The Shape of a Firm's Cost Curves in Long Run and Short Run

A simple real life example will make this clear. The greater the amount of work he has done since the time he started doing a particular work, the greater the experience he attains and with the experi­ence he learns to do things in a better way than before. As you add workers, you will initially see a productivity gain, but as more and more workers are added, their marginal output will fall. The marginal cost curve is usually U-shaped. 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. Three main reasons have been given for the economies of scale which accrue to the firm and due to which cost per unit falls in the beginning.

Cost curve

First, the new techniques of production are adopted at a large scale of production due to which cost per unit falls. Short run decision for a firm is the quickiest and the most risky way to maximise profits in the short period of time. The Average Cost will continue to fall till they reach the minimum point which is the optimum point level of output. In a economy, firms optimize their production process by minimizing cost consistent with each possible level of production, and the result is a cost curve; and firms use cost curves to decide output quantities. In physical and technical state of affairs the quantities of factors of production are assessed. Then on the idea of factor prices the cost of each techniqueof production are evaluated. There­fore, when a point is reached where the abilities of the fixed and indivisible entrepreneur are best utilised, further increases in the scale of operations by increasing other inputs cause the cost per unit of output to rise.

However, it has been asserted that even after most of the economies of scale have been achieved and the firm reaches a minimum optimal scale, given the technology of the industry, the unit cost of production may fall due to some technical economies which it can continue to enjoy even after the minimum optimal scale. In the long run the average cost has changed from Q 0R to Q 1A. This results from the use of indivisible factors and the reaping of internal economies of labour, technical, managerial, marketing etc. 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. This is because the aggregate output by a firm to date determines the degree of learning it has acquired and the efficiency gained by it.

why is the average total cost curve u shaped

If output is increased, average variable costs necessarily increase, because variable costs are things like raw materials that you really need for production. The average cost per unit begins high and drops as production increases. Therefore, since average product first increases, reaches a maximum, then decreases, average variable cost first decreases, reaches its minimum when average product attains its maximum , then increases. Transport: A good system of road, rail, air and sea links will be important to all firms in the area and they all share the advantages of the adequate provision of these links. For instance, in the West Midlands U. The atc curve is also 'u' shaped because it takes its shape from the avc curve, with upturn reflecting onset of diminishing returns to variable factor following article will guide you know why cost u.

For instance, coal mining is especially important in Dhanbad and this is reflected in the type of educational facilities provided, e. This law tells that when the quantity of one variable factor is changed while keeping the quantities of other factors fixed, the total output increases with an increasing rate and then declines with more than proportionate. Marginal costs Marginal cost is the cost of producing one extra unit of output. It means that each production method is divided into sub activitiescorresponding to the various physical and … technical phases of production for the particularcommodity. If he continues under the old scale his average cost will be Q 1T.

Explain the difference chapter 10. Average variable costs are found by dividing total fixed variable costs by output. One by one we are explaining all causes with simple way in following manners. The profits are high and maximised. Suppose the wage rate is Rs. Indivisibility of Factors: Some economists explain economies of scale as arising from the imper­fect divisibility of factors.
