Isocost-isoquant analysis: theory of production: The production function: a figure known as an isoquant diagram (Figure 1). In the graph, goldsmith-hours per. 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.

Now the problem confronting the firm is to reach the highest possible isoquant with its given isocost line. Politics and Social Issues. The least cost factor combination can qnalysis determined by imposing the isoquant map on isocost line. Introduction A rational firm seeks maximization of its profit. This is used to display charts and graphs on articles and the author center. The firm can achieve maximum profits by isocosg that combination of factors which will cost it the least.

isquant This is feature allows you to search the site. Outlay is not sufficient to move to IQ 3. Equilibrium is attained at the point ixoquant the isoquant is tangent to the isocost line.

Unless you are signed in to a HubPages account, all personally identifiable information is anonymized. The cost is minimum, when the input combination is optimal. An isocost line shows the alternative quantities of two factors viz. Isoquants indicate various possibilities of combining two inputs. This condition makes sense: The marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium.


The choice is based on the prices of factors of production at a particular time. For the convenience of the students, we can state them as follows. 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. The absolute value of the slope of the isocost line, with capital plotted vertically and labour plotted horizontally, equals the ratio of unit costs of labour and capital.

Production theory is extended to deal with two variable inputs by the introduction of isoquants. We know that the MRTS is equal to the ratio of the marginal products of isovost two inputs.

Thus, E is the point of equilibrium from where there is no tendency on the part of the producer to move away. Where the isoquant touches but does not cross the lowest isocost line is the least cost position. Isoquant is also called as equal product curve or production indifference curve or constant product curve. Only if a dollar spent on each input is equally productive is the input bundle optimal.

The firm will get its maximum output when it employs OL 0 units of labor and OK 0 units of capital. Rationality on the part of the producer requires anqlysis utilization of resources for optimization of output.


In this equationPL is the price of labour and Pk is the price of capital. Its slope is given by the ratio of the prices of the two factors. The significance of factors of productive resources is that, any two factors are substitutable e. Iso cost line shows various combinations of labour and capital that the firm can buy for a given factor prices. No two factors are perfect substitutes. But, the desire to produce a commodity is not enough. Thus at a anv of equilibrium marginal physical productivities of the two factors must be equal the ratio of their prices.

Isocost-isoquant analysis

Games, Toys, and Hobbies. The minimum-cost ispcost are A, D and E. Assumptions The principle of least-cost combination rests on the following assumptions: Suppose, the producer wants to produce six units of output.

Towards this end, the equal product map has been super imposed on the isocost line NM. Least cost input is a combination where the slope of isoquant is equal to the slope of isocost.

Isocost – Wikipedia

With right angled or L shaped, isoquantinputs can only be combined in fixed proportion in production. With the change in the factor prices the slope of iso cost lien will change.

Iso quant is also known as Production indifference curve.
