What are isoquants?

isoquant analysis

It represents a combination of short-run and long-run adjustments to a slight increase in the rate of output. The firm is also presumed to use m fixed factors, or factors like fixed machinery, salaried staff, etc. Isoquant curve is called production indifference curve since it is an extension of indifference curve analysis from the theory of consumption to the theory of production. Criticisms of the theory The theory of production has been subject to much. Isoquant curves are also known as Equal product or Iso-product or Production Indifference Curves. These include the relationship between the prices of commodities and the prices or wages or rents of the productive factors used to produce them and also the relationships between the prices of commodities and productive factors, on the one hand, and the quantities of these commodities and productive factors that are produced or used, on the other. It assumes that there are no changes in the rest of the economy while individual firms and industries are making the adjustments described in the theory; it neglects changes in the technique of production; and it pays no attention to the risks and uncertainties that becloud all business decisions.

Add Remove The manager of a public supplying electricity to a significant portion of a geographic region presides over an electrical generation facilities that can produce electricity using either natural gas or oil, or some combination of both. Add Remove Many economists believe that an increase in the minimum wage leads to. This, also, is a fundamental theorem of income distribution and one of the most significant theorems in economics. Marginal cost and price The conclusion that marginal cost tends to equal price is important in that it shows how the quantity of output produced by a firm is influenced by the market price. Maximization of long-run profits Relationship between the short run and the long run The theory of long-run profit-maximizing behaviour rests on the short-run theory that has just been presented but is considerably more complex because of two features: 1 long-run cost curves, to be defined below, are more varied in shape than the corresponding short-run cost curves, and 2 the long-run behaviour of an industry cannot be deduced simply from the long-run behaviour of the firms in it because the roster of firms is subject to change. The mapping of the isoquant curve addresses cost minimization problems for producers. If different combinations of two factors yielding equal amount of total output are diagrammatically presented in the form of a curve, then such a curve is called on Isoquant or Iso-product curve.

Finally, in increasing-cost industries average costs rise with the volume of output generally because the firm cannot obtain additional fixed capacity that is as efficient as the plant it already has. Only the simplest aspects of the theory were described above. Automobile and steel manufacturing are leading examples. This is possible in the above figure. The isoquant curve is a contoured line that is drawn through points that produce the same quantity of output, while the quantities of inputs — usually two or more — are changed. It is of the essence of long-run adjustments that they take place by the addition or dismantling of fixed productive capacity by both established firms and new or recently created firms. The firm can produce 100 units of output at point A on this curve by having a combina­tion of 9 units of capital and 5 units of labour.

Economics: Slope of isoquant curve/Marginal rate of substitution

The indifference curve, on the other hand, helps to map out the utility maximization problem that consumers face. The firm will then consider whether it could increase its profits by enlarging its plant. As output increases from a low level, average costs decline to a low plateau. Thus isoquant curve is that curve which shows the different possible combinations of two factor inputs yielding the same amount of output. The usual behaviour of average and marginal variable costs in response to changes in the level of output from a given fixed plant is shown in Figure 3. A number of isoquants representing different amounts of output are known as an isoquant map. It states the amount of product that can be obtained from each and every combination of factors.

The isoquant curve assists firms in making adjustments to inputs to maximize outputs, and thus profits. The most profitable amount of output may be found by using these data. The effect of plant enlargement is to reduce the variable cost of producing high levels of output by reducing the strain on limited production facilities, at the expense of increasing the level of fixed costs. This is one of the most significant theoretical findings in economics. The figure is drawn for some particular fixed plant, and it can be seen that average costs are fairly high for very low levels of output relative to the size of the plant, largely because there is not enough work to keep a well-balanced fully occupied. It is also known as a production indifference curve or a constant product curve. On another level the theory has been charged with excessive simplification.

Such curves are discussed in the standard literature of this subject. Its logic can be perceived directly. For example, perhaps machines can be operated at two possible speeds, fast and slow. Decreasing costs are characteristic of manufacturing in which heavy, automated machinery is economical for large volumes of output. That follows a lot with what I was thinking. It is now possible to derive the relationship between product prices and factor prices, which is the basis of the theory of income distribution.

Isoquant Curve

These are especially damaging to the theory of long-run profit maximization. Thus it means equal quantity or equal output. Thus the quantity that the firm will produce in response to any price can be found in Figure 3 by reading the marginal cost curve, and for this reason the marginal cost curve is said to be the short-run for the firm. An isoproduct curve is a curve along which the maximum achievable rate of production is constant. This diagram is a graphic display of the relationships expressed in the production function. This leads to the concept of the long-run cost curve: the long-run costs of any level of output are the short-run costs of producing that output in the plant that makes those short-run costs as low as possible.

The marginal products are closely related to the marginal rates of substitution previously defined. The available quantity of the first fixed factor is indicated in the formal by k 1 and so on. For example Power plant equipped to burn either oil or gas, various amounts of electric power can be produced by burning gas only or oil only. Finding the cheapest of these is the problem of cost minimization. It is obvious that many more isoquants, in principle an number, could also be drawn. What are the pros and cons of using these tools? Decreasing costs are inconsistent with competitive conditions, since they permit a few large firms to drive all smaller competitors out of business.

Though this is fair enough for a single firm, the fact is that if all firms together attempt to increase their outputs in response to an increase in the price of the product, they are likely to bid up the prices of some or all of the factors of production that they use. It is specific to this example. Each of the curved lines, called an isoquant, will then represent a certain number of necklace chains produced. Though the conclusions were deduced within the of a firm that uses two factors of production, they are clearly applicable in general. An expenditure of v 3 is more than sufficient; and v 2 is the lowest variable cost for which 200 units can be produced. These factors may be substituted for one another.

This set is shown in the following figure, together with the for the output 2. But there are other combinations of variable inputs that could also produce 200 necklace chains per month. In the graph, goldsmith-hours per month are plotted horizontally and the number of feet of gold wire used per month vertically. The isoquant—isocost diagram or the corresponding solution by the means of the calculus solves the short-run cost minimization problem by determining the least-cost combination of variable factors that can produce a given output in a given plant. The two corners of the isoquant correspond to the case in which all the machines in the factory run slowly, and the case in which they all run fast.
