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.

A line joining tangency points of isoquants and isocosts with input prices held constant is called the expansion path.

The chapter examines the theory of production or how firms organize production i. Also called pay-as-you-earn scheme, advance tax is the income tax payabl Iskquants set of isocost lines can be drawn for different levels of factor prices, or different sums of money. Wikimedia Commons has media isoqunts to Isoquants. If the two inputs are perfect substitutes, the resulting isoquant map generated is represented in fig. An isoquant derived from quantity and the Greek word iso, meaning equal is a contour line drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs.

The firm will combine isocostx two inputs in the required ratio to maximize profit. To construct isocost lines we need information about the market prices of the two factors. An isocost line is a locus of points showing the alternative combinations of factors that can be purchased with a fixed amount of money. In the typical case shown in the top figure, with smoothly curved isoquants, isoquaants firm with fixed unit costs of the inputs will have isocost curves that are linear and downward sloped; any point of tangency between an isoquant and an isocost curve represents the cost-minimizing input combination for producing the output level associated with that isoquant.

The assessee will be issoquants for penal int But, the desire to produce a commodity is not enough. The marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium.

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. Table 1 illustrates, by using hypothetical numbers, seven alternative methods of producing six units of output.

Isoqiants isoquant shows the various combination of two inputs that can be used to produce a specific level of output. Privacy policy About WikiEducator Disclaimers. The slope depends on the prices of factors of production and the amount of money which the firm spends on the factors.

This page was last edited on 29 Novemberat This page was last edited on 20 Novemberisoquats 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. Where the isoquant touches but does not cross the lowest isocost line is the least cost position.

An isoquants is also known as equal product curve or iso-product curve. Individuals have to pay tax on the following incomes: Iso quant is also known as Production indifference curve.

The choice is based on the prices of factors of production at a particular time.

We could draw as many isoquants as we like. After reading this chapter, you are expected to learn about: It is known as the actual rate of factor substitution, the rate at which the firm can substitute labour by capital in the market place. 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.

Suppose, the producer wants to produce six units of output.

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. In both cases the factors will have to be employed in optimal combination at which the cost of production will be minimum. Iso quant is sloping downwardso when inputs are used in fixed proportion. A higher isoquant represent lower level of output.


Each return form has two forms of acknowledgements attached to it.

For the convenience of the students, we can state them as follows. Adding one input while holding the other constant eventually leads to decreasing marginal output, and this is reflected in the shape of the isoquant. So, like the consumer the producer has also to operate under a budget resource constraint. An iso-cost line closer to origin indicates a lower total cost outlay. Although the marginal product of an input decreases as you increase the quantity of the input while holding isiquants other inputs constant, the marginal product is never negative in the empirically observed range since a rational firm would never increase an input to isoquajts output.

An isoquant shows what a firm is desirous of producing. To find the least cost combination of inputs to produce a given output, we need to construct such equal cost lines or isocost lines. The supply curve shows the influence of price on the quantity supplied when other factors that influence quantity supplied are hel Username or Email Password.

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.

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

An isocost line shows the alternative quantities of two factors viz. With the change in the factor prices the slope of iso cost lien will change. See all related question in B.
