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 is explained in Panel B of Figure In economics an isocost line sioquant all combinations of inputs which cost the same total amount.

This is known as the stage of diminishing returns. Prices of factors remaining the same, if the total outlay is raised, the isocost curve will shift upward to the right as EF parallel to CD, and if the total outlay is reduced it will shift downwards to the left as AB. To find the least-cost combination of factors for fixed level of output we combine Fig.

This is the economic region of production. If the firm is to maintain the same level of output while reducing capital by one unit, it needs to replace one unit of capital by one unit of labour. We discuss the relation between the returns to a factor law of diminishing returns and returns to scale law of returns to scale on the assumptions that:.

It means that the isoquant must be convex to the origin at every point. The properties of isoquants, as we shall study below, are exactly similar to those of indifference curves. The least cost factor combination can be determined by imposing the isoquant map on isocost line. Each such point shows the equilibrium factor combination for maximising output subject to cost constraint, i.

This page was last modified on 16 Aprilat Iso-cost line K 1 L 1 is just not relevant because the output level represented by the isoquant P is not producible by any factor combination available on this iso-cost line. The output has doubled but the amount of labour employed has not increased proportionately.

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

Iso quant map shows all the possible combinations of labour and capital that can produce different levels isiquant output. At this point, the firm is minimising its cost for producing units. Firstly, an indifference curve represents satisfaction which cannot be measured in physical units. In fact, in between isocodt units of output,etc. Given these assumptions, we first explain the relation between constant return to scale and returns to a variable factor in terms of Figure An isoquant map shows a number of isoquants representing different amounts of output.

Least cost input is a combination where the slope of isoquant is equal to the slope of isocost. Suppose capital isocodt a fixed factor and labour is a variable factor. Connect all these points and we have a curve IQ.

Isoquant indicates various combinations of two factors of production which give the same level iaocost output per unit of time. In this equationPL is the price of labour and Pk is the price of capital. If one of the factors becomes relatively dearer, the isocost line will contract inward to the left. If labour is employed further, we are outside the lower ridge line OB and enter the third stage of the law of variable proportions.

This concept of the diminishing marginal rate of technical substitution DMRTS is parallel to the principle of diminishing marginal rate of substitution in the indifference curve technique. Subsidiary industries crop up to help the main industry.

Iso cost line shows various combinations of labour and capital that the issocost can buy for a given factor prices.

Production theory is extended to deal with two variable inputs by the introduction of isoquants. Specifically, the point of tangency between any isoquant and an isocost line gives the lowest-cost combination of inputs that iaocost produce the level of output associated with that isoquant.

Trade journals, research and training centres appear which help in increasing the productive efficiency of the firms. After reading this chapter, you are expected to learn about: The point where the isocost line is tangent to an isoquant represents the least cost combination of isocostt two factors for producing a given output.

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

Work can be divided into small tasks and workers can be concentrated to narrower range of processes. Both the situations are impossibilities because nothing can be produced either with only labour or only capital. Only if a dollar spent on each input is equally productive is the input bundle optimal. The slope depends on the prices of factors of production and the amount of money which the firm spends on the factors. An isoquant is analogous to an indifference curve in more than one way. The firm cannot attain a higher level of output such as isoquant because of the cost constraint.

With the change in the factor prices the slope of iso cost lien will change. Returns to a factor and returns to scale are two important laws of production. Transport and marketing difficulties emerge.
