Isoquants are graphical representations of the various combinations of inputs that can be used to produce a specific level of output in a production process. They are commonly used in economics to analyze production decisions and to understand how a firm can most efficiently use its resources to produce a given level of output. Isoquants have several important properties that make them useful tools for analyzing production processes.
First, isoquants are downward sloping. This means that as the quantity of one input increases, the quantity of the other input must decrease in order to maintain the same level of output. This property reflects the principle of diminishing returns, which states that as more of a factor of production is used, the marginal product of that factor decreases.
Second, isoquants are convex to the origin. This means that as the quantity of both inputs increases, the marginal rate of technical substitution (MRTS) between the inputs decreases. The MRTS is a measure of how easily one input can be replaced by another in the production process. A convex isoquant indicates that it is easier to substitute one input for another at lower levels of input use, but becomes more difficult as the inputs are used in greater quantities.
Third, isoquants are separable. This means that the input combination that is optimal for producing a given level of output is independent of the input combinations that are optimal for producing other levels of output. This property allows firms to analyze the optimal use of inputs for each level of output separately, rather than having to consider the interactions between different levels of output.
Fourth, isoquants are continuous. This means that there is no discontinuity or jump in the combinations of inputs that can be used to produce a given level of output. This property allows firms to smoothly adjust their input usage as they seek to optimize their production process.
Overall, the properties of isoquants make them useful tools for analyzing production decisions and understanding the most efficient use of inputs in a production process. By considering the downward slope, convexity, separability, and continuity of isoquants, firms can make informed decisions about how to allocate their resources in order to produce a desired level of output.
Properties of Isoquants
When we increase labour, we have to decrease capital to produce a given level of output. Properties of Isoquant Curve The isoquant curve has almost the same properties as are possessed by the indifference curve of the theory of consumer behavior. Like, indifference curves, Iso- quant curves also slope downward from left to right. An iso-cost line is the locus of all the combinations of two factors that a producer can procure from the market at the given factor prices from a given amount of outlay. The output along the isoquant is constant. Production Isoquants: The long-run production function involving the usage of two factors say, capital and labour is represented by isoquants or equal product curves or production indifference curves. If the industry is enjoying increasing returns, then its marginal product increases.
Isoquant Curve in Economics Explained: Properties and Formula
In fact, every point on a given isocost line represents the same total cost. The tangency point shows that optimisation in production is reached when factor prices and marginal product are proportional, with equalised marginal product per rupee. If the total outlay increases, the iso-cost line will shift upward, away from the point of origin, and if the total outlay decreases, the line will shift downward or towards the origin. In order to establish this property, let us suppose, for the sake of argument, that two IQs, viz. This meant that the minimum cost of producing a given output of 150 units is Rs.
Isoquants: Meaning, Assumptions and Properties
The table 1 shows that the five combinations of labour units and units of capital yield the same level of output, i. Isoquant is negatively sloped The isoquant curve is neither upward sloping nor horizontal but always slopes downward from left to right. Left to point C, isoquant I lies above isoquant II. We could draw as many isoquants as we like. In combination B, when 1 unit of labor was added in place of 4 units of capital, the production process still produced 100 units of output. It gives us, just like the production function, what q would be for any particular input combination. This negative slope indicates that, if the producer decreases the amount of capital employed, more labour must be added in order to keep the rate of output constant.

. Therefore, in the above discussion, we have seen that the IQs have four properties: they are negatively sloped, convex to the origin, non-intersecting and a higher IQ represents a higher level of output. The price of the product also comes down. Lastly, the fourth property of IQs that a higher IQ, i. These practices save time in the decision making process, speed up the processing of information, and increase its amount and accuracy.
