Isoquants are graphical representations of the combinations of inputs that can be used to produce a given level of output in the production process of a firm. In other words, an isoquant represents the different ways in which a firm can produce a given level of output using different combinations of inputs such as labor and capital.

Isoquants are typically plotted on a graph with the quantity of one input on the x-axis and the quantity of the other input on the y-axis. The isoquant curve slopes downward to the right, indicating that as the firm increases the quantity of one input, it can decrease the quantity of the other input and still produce the same level of output. This property of isoquants is known as the law of diminishing marginal returns, which states that as the firm increases the quantity of one input while holding the quantity of the other input constant, the marginal product of the input eventually decreases.

Isoquants are useful tools for firms because they can help managers make decisions about the optimal combination of inputs to use in order to minimize costs and maximize profits. For example, if a firm is trying to produce a certain level of output at the lowest possible cost, it can use isoquants to determine the combination of inputs that minimizes the cost of production.

Isoquants are also useful for analyzing changes in the production process of a firm. For example, if a firm introduces a new technology that increases the productivity of one of its inputs, the isoquant curve will shift outward, indicating that the firm can now produce the same level of output using fewer inputs. Similarly, if the price of one of the inputs increases, the isoquant curve will shift inward, indicating that the firm must use more of the other input in order to produce the same level of output.

In summary, isoquants are graphical representations of the combinations of inputs that can be used to produce a given level of output in the production process of a firm. They are useful tools for firms because they can help managers make decisions about the optimal combination of inputs to use and for analyzing changes in the production process.

## Isoquant: Concept, Characteristics and Type Schaum's outline of theory and problems of managerial economics, McGraw-Hill,. It depends on marginal rate of technical substitution MRTS whereas slope of an indifference curve depends on marginal rate of substitution MRS between two commodities consumed by the consumer. Finally, any combination of inputs above or to the right of an isoquant results represents a higher level of output, and vice versa. Fall in output must cancel out the increase in output, so that output level along an isoquant remains fixed. Since different studies define and measure energy efficiency improvements in different ways and for different levels of aggregation, great care must be taken when comparing and interpreting their results. Isoquants are downward-sloping and convex like indifference curves. An isoquant map is a family of isoquants which shows the production function for a good.

## Study Notes on Isoquants ( With Diagram) By joining together A, B and C will get OQ line. If a firm produces to the left of the contour line, then the firm is considered to be operating inefficiently, because they are not maximising use of their available resources. One important point is to be noted here. The linear programming has to be calculated N times, once for each country in the EU28 region. Definition: An isoquant is a curve or locus of points showing all possible combinations of inputs physically capable of producing a certain fixed level of output. Gas and oil are perfect substitutes here. Unless the domestic engineering sector is protected, purchasers will gravitate toward imports and the sector will exhibit stagnant production and excess capacity, much as the Indian textile-machinery sector has done.

## Iso B Marginal benefit curve MB derived from isopleths. Indifference curve provides no information regarding the economic and uneconomic region of consumption. In the figure, isoquant Q 1 represents a lower level of output as compared to isoquant Q 2 and Q 3. Along the isoquant, total output is constant. This concept of the diminishing marginal rate of technical substitution DMRTS is parallel to the principle of diminishing marginal rate of substitution in the indifference curve technique. Thus it means equal quantity or equal product. No other shape of isoquant, whether concave or a straight line, will show such a feature.

## Isoquant Curve Example & Marginal Rate of Technical Substitution 2022 Companies and enterprises use the isoquant curve to make modifications in inputs to maximize manufacturing, and thus enhance growth margins. 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. And, MRTS is equal to the ratio of marginal product of labour MP L to the marginal product of capital MP K. Consequently, NO x causes damage directly as well as indirectly through ozone. Depending on the price of the newer machine, potential buyers may prefer the newer design because a given investment expenditure will result in a larger present discounted value. Both curves IQ1 and IQ2 represent two levels of output.

## Isoquant and isocosts It simply tells that the combinations on a given indifference curve yield more satisfaction than the combination on a lower indifference curve of production. Production function with 2 variable inputs Production function using 2 variable inputs is explained with the help of the Isoquants. First, if area A is less than B, it is better to do nothing ceteris paribus. This implies a negatively sloped isoquant. What are the three types of Isoquants? The MRTS diminishes because the two factors are not perfect substitutes. IQ 1 represents an output level of 100 units whereas IQ2 represents 200 units of output. We have seen that, as MRTS declines, labour is substituted for capital.

## Isoquants An isoquant shows that if the firm have ability to substitute between the two different inputs labour and machines in order to produce the same level of output If the distance between isoquants increases curve shifting upward output increases. Thus it means equal quantity or equal output. Two Isoquants Never Intersect Each Other: Two isoquants representing different levels of output can never intersect. Consider for example the case where the isoquant is globally nonconvex, and the isocost curve is linear. This shape is a result of the fact that if a producer uses more of capital or more of labour or more of both than is necessary, the total product will eventually decline. Diminishing MRTS is expressed graphically by the flattening of the slope of the isoquant.

## Why are Isoquants convex? In this example, a unit of labour and capital cost £6,666 each. Hence, the marginal benefit of abatement is found by adding the demand for particulate abatement vertically to the demand for NO x abatement derived from the demand for ozone abatement. . This diagram separates economic region of production from uneconomic region of production. Isoquants are Convex to the Origin: Like indifference curves, isoquants are convex to the origin. If the isoquant is backward bending and upward sloping, marginal product of any input will be negative, and, hence, this portion of the isoquant may be considered as economically non-sensible region of production.

## Isoquant Properties of an Isoquant : Like an indifference curve in the consumer plane, a production indifference curve or an isoquant has the following properties: i. What does a MRTS 4 mean? It can be used to illustrate either attainable or optimal production possibilities in limited circumstances. Similarly, improvements in energy efficiency at one level of aggregation e. The producer must, therefore, spend OC amount on capital and OL amount on labour. Concept of Isoquant 2. What are the types of isoquant? Conclusion So friends, this was the concept of Properties of Isoquants Properties of Isoquants in Economics.
