In economics an isocost line shows all combinations of inputs which cost the same total amount The isocost line is combined with the isoquant map to determine the optimal production point at any given level of output. Specifically, the point. Isocost-isoquant analysis: theory of production: The production function: a figure known as an isoquant diagram (Figure 1). In the graph, goldsmith-hours per. Isoquants: An isoquant (equal quantity) is a curve that shows the combinations of certain inputs such as Labor (L) and Capital (K) that will produce a certain.

This tendency of diminishing marginal substitutability of factors is apparent from Table Secondly, on an indifference map one can only say that a higher indifference curve gives more satisfaction than a lower one, but it cannot be said how much more or less satisfaction is being derived from one indifference curve as compared to the other, whereas isocoost can easily tell by how much output is greater on a higher isoquant in comparison with a lower isoquant.

In both cases the siocost will have to be employed in optimal combination at which the cost of production will be minimum. Labour is thus being overworked and its marginal product is negative.

Returns to a factor studies the behavior of output when more and more units of the variable factor is combined with the fixed fact Table 1 illustrates, by using hypothetical numbers, seven alternative methods of producing six units of output.

We discuss the relation between the returns isoauant a factor law of diminishing returns and returns to scale law of returns to scale on the assumptions that:.

Where the isoquant touches but does izoquant cross the lowest isocost line is the least cost position.

Subsidiary industries crop up to help the main industry. The person who fills in the return should also complete the entries in the acknowledgement fo At this point, the firm is maximising its output level of units by employing the optimal combination of OM of capital and ON of labour, given its cost outlay CL. This proves that the marginal returns or physical productivity of isoquanr variable factor, labour, have diminished.


Explain a firm’s equilibrium with the help of isoquants and isocost line. –

This shows that the marginal returns of the variable factor, labour, have increased even when there are increasing returns to scale. The firm also maximises its profits by maximising its output, given its cost outlay and the prices of the two factors. An isoquant map shows a number of isoquants representing different amounts of output. Constant returns to scale also result when factors of production are perfectly divisible, substitutable, homogeneous and their supplies are perfectly elastic at given prices.

In the case of an isoquant the product can be measured in physical units. The slope of an isoquant gives the marginal rate of technical substitution MKTS defined as the increase in the quantity of one factor that is required to replace a unit decrease in another factor, when output is held constant along any isoquant.

At point P, the slope of the isoquant curve is equal to the slope of the isocost line CL. Ridge lines joins points on the various isoquants where the isoquants have zero slope and thus zero MRTSlk. The different tax authorities and their functions are outlined below: The producer can attain P level of output by the factor combination represented by point E, which is on iso-cost line K 2 L 2. If all points of tangency like LMN are joined by a line, it is known as an output- factor curve or least-outlay curve or the expansion path of a firm.

Large management creates difficulties of control and rigidities. This is picturised by his budget line called isocost line. At this point, the firm is minimising its cost for producing units.

On the incomes they have earned themselves. With right angled or L shaped, isoquantinputs isoquang only be combined in fixed proportion in production.

Explain a firm’s equilibrium with the help of isoquants and isocost line.

The conditions for the equilibrium of the firm are the same, as discussed above. Navigation menu Personal tools Log in Request account. The producer minimises his costs by employing OB amount of capital plus OA amount of labour determined, by the tangency of the iso-quant P with the iso-cost line K 2 L 2. The increasing returns to scale are attributed to the existence of indivisibilities in machines, management, labour, finance, etc.

It may be able to install better machines, sell its products more easily, borrow money cheaply, procure the services of more efficient manager and workers, etc. Advance Tax refers to paying a part of your taxes before the end of the ispquant year.

But this is logically absurd because S combination is ksocost productive as R and A combination produces as much as B. To find the least-cost combination of factors for fixed level of output we combine Fig.

At point S, the marginal rate of technical substitution between the two factors increases if move to the right m or left on the curve lQ 1. They form the uneconomic regions of production. To these internal diseconomies are added external diseconomies of scale.

Production theory is extended to deal with two variable inputs by the introduction of isoquants. By moving from F to E or from G to E, the producer attains the same output level at a lower cost.
