ISOQUANTS AND ISOCOSTS PDF

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.

From the theory of production where only one or two inputs are variable, we proceed to examine cases in which all inputs are variable. Isoquants are typically drawn along with isocost curves in capital-labor graphsshowing the technological tradeoff between capital and labor in the production functionand the decreasing marginal returns of both inputs.

Fundamental Methods of Mathematical Economics Third ed. Finally, any combination of inputs above or to the right of an isoquant results in more output than any point on the isoquant.

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.

As with isoocsts curves, two isoquants can never cross. 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.

Equivalently, it gives the maximum level of output that can be produced for a given total cost of inputs.

The calculation of taxable income is done for the individual who is an Indian resident.

It is also known isoauants the equal product curve. Therefore, the only way to maximise profit is to minimise cost. Isoquants are negatively sloped in the economically relevant range, convex to the origin and do not intersect.

An isoquant shows the various combination of two inputs that can be used to produce a specific level of output. Privacy policy About WikiEducator Disclaimers.

After reading this chapter, you are expected to learn about: A line joining tangency points of isoquants and isocosts with input prices held constant is called the expansion path. If the two inputs are perfect complements, the isoquant map takes the form of fig.

The firm would not operate on the positively sloped portion of an isoquant because it could produce the same level of quantity with less capital and labour. In fact, every point on a given isocost line represents the same total cost. All these and other various combinations are shown in Fig.

The marginal rate of technical substitution of labour for capital must be diminishing at the point of equilibrium. If the distance between those isoquants increases as output increases, the firm’s production function is exhibiting decreasing returns to scale; doubling both inputs will result in placement on an isoquant with less than double the output of the previous isoquant.

The producer minimises his costs by employing OB amount of capital plus OA amount of labour determined, by the tangency of the iso-quant P with the iso-cost line K 2 L 2. See full list of related question in B. Suppose, the producer wants to produce six units of output. For example, the cost would be Rs.

A; with a given level of production Q3, input X can be replaced by input Y at an unchanging rate. The 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. Isoquant indicates various combinations of two factors of production which give the same level of output per unit of time. Where the isoquant touches but does not cross the lowest isocost line is the least cost position.

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

The perfect substitute inputs do not experience decreasing marginal rates of return when they are substituted for each other in the production function. This is picturised by his budget line called isocost line. In this equationPL is the price of labour and Pk is the price of capital. This indicates that one factor can be used a little more and other factor a little less, without changing the level of output.

A cost-minimizing input bundle is a point on the isoquant for the given y that is on the lowest possible isocost isoqjants. If the two inputs are perfect substitutes, the resulting isoquant map generated is represented in fig. Here, the firm seeks to minimise its cost of producing a given level of output. If a producer seeks to minimize the cost of producing a given amount of output the condition of the equilibrium, is that the marginal rate of technical substitution must be equal to the factor price ratio.

A set of isocost lines can be drawn for different levels of factor prices, or different sums of money.
