Returns to scale refer to the changes in output that result from a change in the inputs of a production process. There are three types of returns to scale: increasing, decreasing, and constant.
Increasing returns to scale occur when an increase in inputs leads to a more than proportional increase in output. This can be caused by economies of scale, which are cost savings that arise from increased production. For example, a company may experience increasing returns to scale if it is able to negotiate bulk discounts on raw materials or if it is able to spread fixed costs over a larger production volume.
Decreasing returns to scale occur when an increase in inputs leads to a less than proportional increase in output. This can be caused by diseconomies of scale, which are cost increases that arise from increased production. For example, a company may experience decreasing returns to scale if it is required to hire additional management or administrative staff to oversee a larger production volume, or if it encounters logistical challenges in distributing its products to a wider market.
Constant returns to scale occur when an increase in inputs leads to a proportional increase in output. In other words, the ratio of output to inputs remains constant. This can occur when a production process is operating at an optimal level, where all inputs are being used efficiently and there are no economies or diseconomies of scale.
It is important to note that returns to scale are not the same as economies of scale, which refer specifically to cost savings that arise from increased production. Returns to scale take into account both the change in output and the change in cost, while economies of scale only consider the change in cost.
In conclusion, understanding the types of returns to scale is important for businesses, as it can help them determine the most efficient and cost-effective production methods. Increasing returns to scale can lead to cost savings, while decreasing returns to scale can indicate the need for cost-cutting measures. Constant returns to scale may indicate that a production process is operating at an optimal level.
Returns to Scale: Meaning, Cobb Douglas Production Function, Examples
But in case of decreasing returns to scale, output increases by 10 units, which is less than double. The input is the number of 40-hour employees in March 2016 and the output is the total amount of students registered in March 2016. The rate of change of outputs is a measure of returns to scale as it shows the production levels. Management Science, 30 9 : 1078-1092. To produce 100 units, the firm uses ОС + OL quantities of capital and labour and to double the output to 200 units, double the quantities of labour and capital are required so that ОС 2 + OL 2 lead to this output level at point N. Constant returns to scale When a proportionate change in output equals the proportionate change in output, we speak of constant returns to scale.
Formula and Calculation of Returns to Scale The mathematically gifted among us may be interested in calculating returns to scale. There are three kinds of returns to scale: constant returns to scale CRS , increasing returns to scale IRS , and decreasing returns to scale DRS. Although output increases by 30 units each time, the increase in output is still greater than the increase in input. In this stage, any increase in the inputs results in a direct increment of outputs at the same rate. Like all other stages of production, the IRS stage also cannot be maintained forever. Therefore, returns to scale is a term related to the production of goods and services.
What Is Returns To Scale? Definition, Assumption, Types
In figure 10, we see that increase in factors of production i. Considering the production function studied in Economics, the downward concavity with positive slope is the format of frontiers that express the technology of firms with a high scale of production, and, therefore, the increase of inputs will reduce the marginal productivity of outputs. On the other hand, returns to scale relate to the long period production function when a firm changes its scale of production by changing one or more of its factors. The size increases the efficiency of all inputs and the increasing returns operates. It shows the relationship between inputs and outputs in a production process which is crucial because any imbalance in production would mean that supply is affected negatively. In the long run, all factors of production are variable and subject to change in response to a given increase in production scale.
Returns to Scale and Cobb Douglas Function: With Diagrams & Examples
The DEA-BCC model presents an efficient convex frontier. It is clear from diagram 9. The phenomenon of CRS is generally seen in the middle stages of the production process. This outcome is termed increasing returns to scale IRS. What is meant by return to scale? In other words, comparing a high scale efficient BCC DMU to another which is also efficient, with a shorter scale, necessarily the DMU with more inputs presents a lesser marginal productivity. European Journal of Operational Research, 88 3 : 525-536.
3 Most Important Types of Returns to Scale in Production
The concept of returns to scale is a long-run concept, because it refers to a case where all inputs are variable. In practice he is fixed and indivisible input and on account of change in other variable inputs the ratio under the large scale leads to imbalances and the law of diminishing returns to scale operates. . What are the three types of returns to scale? Here, 2 units of labour and 3 units of capital produced 200 kg of paddy. The factors of production are labor, land, capital, and entrepreneurship.

Article Link to be Hyperlinked For eg: Source: 1 — Constant Returns To Scale It means that increasing the input in proportion to the output gives the same level of increase in the output during the production. All the factors are increased or decreased together. Although the BCC frontier shows a benevolence over CCR and considers efficient DMUs with lower productivity than efficient CCR; there are cases that the BCC downward border neglects DMUs that have marginally increasing productivity and therefore should be considered efficient as well. New York: Harcourt Brace Jovanovich. When the demand is high, producers need to be in this segment of production to get maximum benefits.

The indivisibility of factors is another reason for this. The distance on scale line OP are equal. If the output is less than doubled, then DRS occurs and if it is more than doubled, then IRS occurs. An introduction to the economic theory of market behavior: microeconomics from a Walrasian perspective. This kind of frontier could consider some DMUs efficient that work on a small scale of production, and therefore, cannot reach the level of efficiency of the most productive DMU. What is diminishing returns to scale? It means if all inputs are doubled, output will also increase at the faster rate than double.
Returns to Scale and Returns to Factor (With Diagram)
A Increasing Returns to Scale: Increasing returns to scale arises when output increases in a greater proportion compared to the increase in the inputs. WSEAS Transactions on Systems, 7 5 : 510-520. In other words, the law of returns to scale states when there are a proportionate change in the amounts of inputs, the behavior of output also changes. Departament of Economics, Ohio State University. Types of Returns to Scale 3. When quantity of both the inputs are doubled, i. When a proportionate increase in all inputs results in the rise in output by the same proportion, the production function is said to exhibit Constant returns to scale CRS.
This behavior of output with the increase in scale of operation is termed as increasing returns to scale, constant returns to scale and diminishing returns to scale. If output increases by the same proportional change as all inputs change then there are constant returns to scale CRS. Primont 1995 Multi-Output Production and Duality: Theory and Applications. The distance between iso-product curves is indicated by E, E 1, E 2 and E 3. This is known as homogeneous production function.
