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. An isoquant is a contour line drawn through the set of points at which the same quantity of Isoquants are typically drawn along with isocost curves in capital- labor graphs, showing the technological tradeoff between capital and labor in the . 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.

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

To find the least cost combination of inputs to produce a given output, we need to construct such equal cost lines or isocost lines. It looks for that factor combination that is on the lowest of the isocost lines. This page has been accessedtimes. This is picturised by his budget line called isocost line. Retrieved from ” http: Alternative Objectives of Business Firms Economics. Its slope is given by the ratio of the prices of the two factors.

It is responsible for administering following direct taxation acts passe Least cost input is a combination where the slope of isoquant is equal to the slope of isocost.

From Wikipedia, the free encyclopedia. This condition makes sense: A line joining tangency points of isoquants and isocosts with input prices held constant is called the expansion path.

If, in the short run, its total output remains fixed due to capacity constraint and if it is a price-taker i. Therefore, the only way to maximise profit is to minimise cost.

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

Isoquant is also called as equal product curve or production indifference curve or constant product curve. This page was last edited on 20 Novemberat 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. Individuals have to pay tax on the following incomes: This page was last modified on 16 Aprilat Thus at a point of equilibrium marginal physical productivities of the two factors must be equal the ratio of their prices.


We could draw as many isoquants as we like. In other projects Wikimedia Commons. Determination of factor prices in a competitive market: Also, every possible combination of inputs is on an isoquant. In this section we examine the characteristics of isoquants, define the economic region of production and consider the special cases where the commodities can only be produced with least cost factor combination.

The iso cost line will shift to the right when money spent on factors increases or firm could buy more as the factor prices are given. An isoquant shows that extent to which the firm in question has the ability to substitute between the two different inputs at will in order to produce the same level of output.

Isoquant and Isocost Lines (With Diagram) | Economics

MKTS is, in fact, the ratio of the marginal products of the factors. The focus of this chapter is on the firm.

A; with a given level of production Q3, input X can be replaced by input Y at an unchanging rate. Iso quant map shows all the possible combinations of labour and capital that can produce different levels of output.

The supply curve shows the influence of price on the quantity supplied when other factors izoquants influence quantity supplied are hel From the isoquant map, we can generate the total product curve of each input by holding the quantity of the other input constant. By moving from F to E or from G to E, the producer attains the same output level at a lower cost. Here, the firm seeks to minimise its cost of producing a given level of output. Fundamental Methods of Mathematical Economics Third ed.


According to the Ispcosts theory of factor pricing, price o All the isocost lines in the diagram have the same slope because the relative prices of labour and capital are the same.

The long-run production function of a firm involving the usage of two factors, say, capital and labour is represented by equal-product curve or isoquant. The assessee will be liable for penal int Ridge lines joins points on the various isoquants where the isoquants have zero slope and thus zero MRTSlk. Thus, profit maximisation and cost minimisation are the two sides of the same coin. If the two inputs are perfect complements, the isoquant map takes the form of fig.

An indifference curve is the locus of points indicating particular combinations of goods from which the consumer derives the same Isoquants are negatively sloped in the economically relevant range, convex to the origin and do not intersect. Increasing returns to scale can be obtained only upto a point. From the theory of production where only one or two inputs are variable, we proceed to examine cases in which all inputs are variable. These alternatives are shown also in Fig. The firm can achieve maximum profits by choosing that combination of factors which will cost it the least.

The essential condition is that the slope of the isocost line must equal the slope of the isoquant. Moreover, supply depends on cost of production. 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:.
