The law of return to scale in economics is a concept that refers to the relationship between the inputs (such as labor and capital) used in the production process and the resulting output. It is a key factor in determining the efficiency and profitability of a production process and can have significant implications for the overall competitiveness of a firm or industry.
There are three main types of return to scale: increasing, decreasing, and constant. Increasing return to scale occurs when an increase in the inputs used in the production process leads to a more than proportional increase in output. This can be due to economies of scale, which are cost advantages that arise from an increase in the scale of production. For example, if a company is able to produce a product at a lower cost by increasing the size of its factory or purchasing more advanced machinery, it will experience increasing returns to scale.
On the other hand, decreasing return to scale occurs when an increase in inputs leads to a less than proportional increase in output. This can be due to diseconomies of scale, which are cost disadvantages that arise from an increase in the scale of production. For example, a company may experience decreasing returns to scale if it becomes too large and inefficient, or if it faces bottlenecks or other production constraints that limit its ability to increase output.
Finally, constant return to scale occurs when an increase in inputs leads to a proportional increase in output. This is often the case when a company is operating at optimal efficiency, with all inputs being utilized effectively to produce output.
The law of return to scale is an important concept in economics because it helps to explain why some firms and industries are more competitive than others. Firms that experience increasing returns to scale are able to produce goods and services at a lower cost, which allows them to be more competitive in the marketplace. On the other hand, firms that experience decreasing returns to scale may struggle to compete, as they are unable to produce goods and services as efficiently as their rivals.
In conclusion, the law of return to scale is a key concept in economics that helps to explain the relationship between inputs and output in the production process. Understanding this relationship is important for firms and industries looking to optimize their operations and remain competitive in the marketplace.
Returns to Scale
The two mayÂbe clearly distinguished. These three possibilities result in three forms of returns to scale. An industry can exhibit constant returns to scale, increasing returns to scale or decreasing returns to scale. The chief reason of this kind of behaviour is that when, in the beginning, the scale of production is increased, increased division of labour becomes possible and is adopted and, as a result thereof, output increases rather rapidly.

The Laws of Returns to Scale explains the behavior of long-run This law answers the question that how does total output changes when both the inputs are increased proportionately and simultaneously.
The main cause of the operation of diminishing returns to scale is that internal and external economies are less than internal and external diseconomies. Being prudent means making wise decisions based on principal and managing your practical affairs in a shrewd and discreet manner. As shown in the above figure, the isoquants IQ 1, IQ 2, and IQ 3 represent 100 units, 200 units, and 300 units of output respectively. ADVERTISEMENTS: In the above table, we see that at the outset when we employ one worker on three acres, of land, the total product is 2 quintals. Here, proportionate change in output ΔQ is lower than that of inputs ΔN , so this reflects decreasing returns to scale.
Increasing Returns to Scale Increasing returns to scale indicates a greater percentage increase in output than the percentage increase in input. An increasing returns to scale occurs when the output increases by a larger proportion than the increase in inputs during the production process. Thus A homogeneous function is a function such that if each of the inputs is multiplied by k, then k can be completely factored out of the function. What Does It Mean? This implies that length and breadth of room get doubled. If the inputs are increased by 20%, output increases by 10%. It means, if inputs are doubled, output will be less than doubled.

In the long run, output can be increased by increasing all factors in the same proportion. When the technology shows increasing or decreasing returns to scale it may or may not imply a homogeneous production function. Under increasing returns to scale, the change in output is more than k-fold, under decreasing returns to scale; it is less than k- fold. For example, a firm exhibits increasing returns to scale if its output more than doubles when all of its inputs are doubled. Firms that exhibit constant returns to scale often do so because, in order to expand, the firm essentially just replicates existing processes rather than reorganizing the use of capital and labor.
Increasing returns to scale ii. If the inputs are increased by 10%, output increases by 20%. In the long run all factors of production are variable.

This shows increasing returns to scale. In the short run output may be increased by using more of the variable factor s , while capital and possibly other factors as well are kept constant. The laws of returns to scale refer to the effects of scale relationships. Similarly, movement from combination B to C shows an increase in output by 100 % because of an increase in input by 50%. This is shown by the second expression above, where a more general multiplier of a where a is greater than 1 is used in place of the number 2. Now to increase output, we double the scale, but the total product increases to more than double to 5 quintals instead of 4 quintals and when the scale is trebled, the total product increases from 5 quintals to 9 quintals—the increase this time being 4 quintals as against 3 in the previous case. Generally Accepted Accounting Principles incorporate the prudence concept in many accounting standards, which for example require you to write down fixed assets when their fair values fall below their book values, but which do not allow you to write up fixed assets when the reverse occurs.
Law of Returns to Scale : Definition, Explanation and Its Types
Leather, for example, is less commonly utilised in its raw state until it is converted into attractive products such as shoes, bags, and other accessories. This means that there is a constant proportion of the increase in input. It means when the output increases in the same proportion as the increase in all input, it is called constant returns to scale. ADVERTISEMENTS: Similarly, when we increase the scale, i. To increase the scale of production means that all factors being used in production can be increased at will and indefinitely. There are three possibilities for total production function when all inputs increase: a increase at increasing rate, b increase at a fixed rate or c increase at a decreasing rate. Because there are advantages to production at high level, large companies are at considerable advantage as compared to small firms.
Example Barry's Barbershop was experiencing what it thought was overwhelming customer purchases. Read also What causes hydronephrosis in both kidneys? In short, the tendency under the prudence concept is to either not recognize profits or to at least delay their recognition until the underlying transactions are more certain. This results in a constant increase in output too and shows constant returns to scale. In constant returns to scale, inputs are divisible and production function is homogeneous. In other words, there is at least one factor of production which cannot be varied at will and hence, when more output is desired, the proportion among the factors of production used must change.
