Finding the conditions for cost minimization is a little bit different for Isoquant and Isocost lines. Instead of finding the optimal quantity level for a. 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.

To find the least-cost combination of factors for fixed level of output we combine Fig. All the units of both the factors are homogeneous The prices of the factor units are given The total money outlay is also given There is perfect competition in the factor-market. Views Read View source View history. Non-consent will result in ComScore only processing obfuscated personal data. The firm can maximize its profits either by maximizing the level of output for a given cost or by minimizing the cost of producing a given output.

For more information on managing or withdrawing consents and how we handle data, visit our Privacy Policy at: So the condition that the MRTS be equal to the input cost ratio is equivalent to the condition that the marginal product qnd dollar is equal for the two inputs.

The choice is based on the prices of factors of production at a particular time. Each such point shows the equilibrium factor combination for maximising output subject to cost constraint, i. An isoquant shows what a firm is desirous of producing. Isoquant indicates various combinations of two factors of production which give the same level of output per unit of time.

Production theory is extended to deal with two variable inputs by the introduction of isoquants. The marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium. Thus, an isocost line gives all combinations of labor and capital at equal cost. Where the isoquant touches but does not cross the lowest isocost line is the least cost position.


In this equationPL is the price of labour and Pk is the price of capital.

Profit Maximization Through the Technique of Isoquant and Isocost Line

Iso cost line shows various combinations of labour and capital that the firm can buy for a given factor prices. For example, suppose, the price of labour is Re.

While going through this analysis students may feel it is a revision of the indifference curve and the budget line. When the amount aand money spent by the firm changes, the isocost line may shift but its slope remains the same.

It looks for that factor combination that is on the lowest of the isocost lines. Likewise, the sioquant line will shift to the right if the outlay of the firm increases. Iso quants are equal revenue lines.

After reading this chapter, you are expected to learn about: Other product and company names shown may be trademarks of their respective owners. MKTS is, in fact, the ratio of the marginal products of the factors. The iso quant closer to the origin indicates a lower level of output. The minimum-cost points are A, D and E. 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.

It is a graphical representation of various combinations of inputs say Labour L and capital K which give an equal level of output per unit of time. In economics an isocost line shows all combinations of inputs which cost the same total amount.


This is used to display charts and graphs on articles and the author center. Equilibrium is attained at the point where the isoquant is tangent to the isocost line.


The focus of this chapter is on the firm. This page was last modified on 16 Aprilat The producer must have sufficient capacity to buy necessary factor inputs to be able to reach its isoocst production level.

The long-run production function of a firm involving the usage of two isoqaunt, say, capital and labour is represented by equal-product curve or iscoost. The least cost factor combination can be determined by imposing the isoquant map on isocost line.

Moreover, supply depends on cost of production. Capital and labor are the two factors involved in production. A change in factor price makes changes in the slope of isocost lines as shown in the figure.

We can see that the shape of isoquant plays an important a role in the production theory as the shape of indifference curve in the consumption theory.

No analywis is shared with Facebook unless you engage with this feature. We may now speak a few words about the slopes of isoquant and an isocost line. The equilibrium position of the firm can also be explained in terms of the equality between MRTS and the factor price ratio.

To construct isocost lines we need information about the market prices of the two factors. A rational firm seeks maximization of its profit.
