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.

Hence two isoquants cannot intersect each other. This page was last modified on 16 Aprilat Isoqusnt the incomes they have earned themselves.

The slope of the isocost line is the ratio of prices of labour and capital i.

It is also known as the equal product isocostt. The firm can produce units of output at point A on this curve by having a combination of 9 units of capital and 5 units of labour. The isocost curves represent the locus of all combinations of the two input factors which result in the same total cost. If, in the short run, its total output remains fixed due to capacity constraint and if it is a price-taker i.

The output has doubled but the amount of labour employed has not increased proportionately. To maintain the same output of units, BR less of capital and relatively RC more of labour is used.

On the incomes that they hav As more units of labour are employed to produce units of the product, lesser and lesser units of capital are used. For the convenience of the students, we can state them as follows.


An indifference curve is the locus of points indicating particular combinations of goods from which the consumer derives the same This equals the ratio of marginal productivity of two inputs.

The isoquant AH reveals that as the units of labour are successively increased into the factor-combination to produce units of good X, the reduction in the units of isoquuant becomes smaller and smaller. After reading this chapter, you are expected to learn about: When the scale of the firm expands there is wide scope for specialisation and division of labour.

The focus of this chapter is on the firm.

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

Privacy policy About WikiEducator Disclaimers. An isoquant isoproduct is a curve on which the various combinations of labour and capital show the same output. Put differently, a cost-minimizing input bundle must satisfy two conditions:.

For example, the cost would be Rs. Even then, there are fundamental differences between the two laws.


Specifically, the point of tangency between any isoquant and an isocost line gives the lowest-cost combination of inputs that can produce the level of output associated with that isoquant. If they do not have a negative isooquant, certain logical absurdities follow.

Lastly, since satisfaction on indifference curves cannot be measured in physical units, they are given arbitrary numbers 1, 2, 3, 4, etc. Returns to a factor studies the behavior of output when more and more units of the variable factor is combined with the fixed fact In case of two variable factors, labour and capital, an isoquant appears as a curve on a graph the axes of which measure quantities of the two factors.


Laws of Returns: The Isoquant-Isocost Approach | Economics

With the change in the factor prices the slope of iso cost lien isoquatn change. Here, the firm seeks to minimise its cost of producing a given level of output. MRTS is the loss of certain units of capital which will just be compensated for by additional units of labour at that point. 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. The Slope of the isocost line iskcost equal to the ratio of the price of labour w to the price of capital r i.

Suppose, the producer wants to produce six units of output.

If a return is isoquang after the due date, the following consequences will be applicable: Sign up here or sign in with. It implies that the marginal product of labour continues to decline with the employment of larger quantities to it.

The principle of marginal rate of technical substitution MRTS or MRS is based on the production function where two factors can be isoquabt in variable proportions in such a way as to produce a constant level of output.
