The Law of Diminishing Returns

Diminishing returns is also known as the law of Diminishing Returns. The law of diminishing marginal productivity states the law of Diminishing Returns. The law of Diminishing Returns occurs when there is a decrease in the marginal output of the production process as a consequence of an increase in the amount of a single factor of production, while the amounts of other parameters of production remain constant. The theories of production describe the law of Diminishing Returns as a fundamental principle of economics.

According to the law of diminishing marginal returns, counting an additional factor of production results in outcomes of small growth. After some ideal level of volume is achieved, the adding of any bigger amounts of a factor of production will only yield reduced per-unit incremental returns.

The law of Diminishing Returns is quickly applicable in the fields of agriculture, mining, forests, fisheries and building industries.

Definition of Law of Diminishing Returns

As per economists, the law of Diminishing Returns is the phenomenon when more and more units of a changing input are to be used. On a given quantity of fixed data, the total output may initially increase at an increasing rate and then at a constant rate. The fact that It will eventually increase at a decreasing rate explains the law of Diminishing Returns.

Various economists have defined the law of Diminishing Returns.

When the total output initially increases with an increase in changing input at a given quantity of fixed data, but it starts decreasing after a point of time, illustrates the law of Diminishing Returns.

The significance of the law of Diminishing Returns can be understood by referring to the theory of production.

To properly illustrate the law of Diminishing Returns, some examples are given in this article

The law of Diminishing Returns owes its origin to the efforts of early economists such as James Steuart, David Ricardo, Jacques Turgot, Adam Smith, Johann Heinrich von and Thomas Robart Malthus. These economists propounded the definition of the law of Diminishing Returns.

An example to further illustrate the law of Diminishing Returns: Let’s take an example of a firm that has a set stock of tools and machines, and an uneven supply of labour. As the number of workers increases in the firm, the total output of the firm rises, but at an ever-decreasing rate. It is due to this reason that after a certain point, the firm gets overcrowded and workers start to form lines to use the machines. The permanent solution to this problem is to increase the stock of capital, buy more machinery and build more firms. The above-provided example discusses the law of Diminishing Returns.

Significance of the Law of Diminishing Returns

The law of Diminishing Returns states that the result of adding a factor of production is a smaller increase in output. The addition of any amount of a factor of production, after some best possible level of capacity utilization, will inevitably capitulate decreased per-unit incremental returns. Various factors can be given to illustrate the law of Diminishing Returns.

There are many significant laws of Diminishing Returns. In mathematics, the optimization theory explains the law of diminishing returns as equivalent to a second-order condition. This theory makes perfect sense in economics.

Let us take an example to illustrate the law of diminishing returns. Suppose that the profits of a given company do not decrease with higher levels of production, it could mean that the company would decide to produce an infinite amount of their product for the same Infinitum benefit and returns. Like this, there can be various scenarios for a better understanding of the definition of the law of Diminishing Returns.

The Theory of Production explains the Law of Diminishing Returns

The significance of the law of Diminishing Returns can help in the formulation of various economic policies, to explain the tax difference in the income of different classes

In short, the Law of Diminishing Returns is a perfect phenomenon for the maximization of profit. Failing to prove this second-order condition will mean that the person is minimizing the returns, instead of maximizing them.

The law of Diminishing Returns states that in a production process with which all other factors are fixed except one if the quantity of the variable factor increases by a fixed rate, the level of production will increase by a decreasing rate.

Assumptions

The definition of the law of Diminishing Returns gives some assumptions, which are as follows-

• Homogeneous variable factors

• The measurement of output

• The law of Diminishing Returns states that this law applies only when there is no change.

The law of the Diminishing Returns indicates the following factors:

• Fixed factors of production

• Scarce factors

• Lack of perfect alternatives

• Optimum production

The above-mentioned operation shows the significance of the law of Diminishing Returns.

Did you Know?

Historically, economists were worried that Diminishing Returns would lead to global misery and the gradual ending of human civilization. They saw the application of Diminishing Returns to farmland and observed that at a fixed point any given acre of land has an optimal result of food output per employee.

Economists have for a long time defined the law of diminishing marginal returns roughly and incompatibly. To economists of today’s times, diminishing returns occur only and only when a marginal product goes down at a growing rate of a variable homogeneous input. But economists of earlier times have always confused short-run and long-run returns, average and marginal returns, homogeneous and heterogeneous inputs, and much more. The law of diminishing returns is rooted back in the 18th century and has evolved ever since.
