In economics an isocost line shows all combinations of inputs which cost the same total amount given total cost of inputs. A line joining tangency points of isoquants and isocosts (with input prices held constant) is called the expansion path. 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. Class 3 isocosts & isoquants. 1. ISOQUANTS Equal Quantity of Production; 2. MEANING OF ISOQUANTS • Isoquants are the curves, which.

Cost minimisation occurs when an isoquant is just tangent to but does not cross an isocost line.

## Isoquant and Isocost Lines (With Diagram) | Economics

The producer must have sufficient capacity to buy necessary factor inputs to be able to reach its desired production level. 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.

The chapter examines the theory of production or how firms organize production i. With right angled or L shaped, isoquantinputs can only be combined in fixed proportion in production. In both cases the factors will have to be employed in optimal combination at which the cost of production will be minimum.

## Isocost-isoquant analysis

From the isoquant map, we can generate the total product curve of each input by holding the quantity of the other input constant. Isoquants are negatively sloped in the economically relevant range, convex to the origin and do not intersect. It looks for that factor combination that is on the lowest of the isocost lines. Iso quants are equal revenue lines.

We could draw as many isoquants as we like.

A higher isoquant represent lower level of output. Isocost, abbreviated as IQs, possess the same properties as those of the indifference curves. Top 14 Peculiarities of Labour Production Economics. Isoquants are typically drawn as being convex to the origin because of the assumed substitutability of inputs. An isoquant shows what a firm is desirous of producing. 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.

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. If, in the short run, its total output remains fixed due to capacity constraint and if it is a price-taker i.

This page has been accessedtimes. 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. Suppose, the producer wants to produce six units of output. Retrieved from ” https: When the amount of money spent by the firm changes, the isocost isocoshs may shift but its slope remains the same.

Iso quant map isowuants all the possible combinations of labour and capital that can produce different levels of output. Navigation menu Personal tools Log in Request account.

### Isocost-isoquant analysis | economics |

If the price of labour falls the firm could buy more of labour and the line will shift away from the origin. The choice is based on the prices of factors of production at a particular time.

Isocosta find the least-cost combination of factors for fixed level of output we combine Fig.

For example, the cost would be Rs. Views Read Edit View history. The minimum-cost points are A, D and E.

No two factors are perfect substitutes. Views Read View source View history. The marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium. These alternatives are shown also isiquants Fig. Therefore, the only way to maximise profit is to minimise cost. An isocost line is a locus of points showing the alternative combinations of factors that can be purchased with a fixed amount of money.

If the isoquants are smooth and convex to the origin and the cost-minimizing input bundle involves a positive amount of each input, then this bundle satisfies the following two conditions:.

Equivalently, it gives the maximum isocoss of output that can be produced for a given total cost of inputs. A cost-minimizing input bundle is a point on the isoquant for the given y that is on the lowest possible isocost line. The absolute value of the slope of the isocost line, andd capital plotted vertically and labour plotted horizontally, equals the ratio of unit costs of labour and capital.

A line joining tangency points isocots isoquants and isocosts with input prices held constant is called the expansion path. Alternative Objectives of Business Firms Economics.

Jsoquants cost-minimization problem of the firm is to choose an input bundle KL feasible for the output level y that costs as little as possible. And isoquant must be convex to the origin.
