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 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. The law of Diminishing Returns is quickly applicable in the fields of agriculture, mining, forests, fisheries and building industries. 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 the 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 giving in this article.
These economists propounded the definition of the law of Diminishing Returns. As the number of workers increases in the firm, the total output of the firm rises, but, at an ever-decreasing rate. Keeping control of large numbers of employees across multiple facilities can be inefficient and expensive. Therefore, expanding production may sometimes affect efficiency up to the point when the overall profit actually decreases.
Expanding the production process may lead to a loss of motivation and a decrease in employee morale. When employees experience difficulty connecting to their company, the result may be a decrease in productivity that makes an increase in production more expensive. The law of diminishing returns and the diseconomies of scale are similar in the sense that they are both ways in which an organization can decrease its production efficiency when the input increases.
However, the two concepts are significantly different, as the law of diminishing returns refers to a decrease in production output as a result of an increase in only one input, while diseconomies of scale refer to an increase in cost per unit as a result of an increase in output.
Another major difference between the law of diminishing returns and the diseconomies of scale is that the first can typically only occur in the short term, while the second is an issue that can take a long time to happen.

A factory machine requires two employees to operate and is capable of running for 24 hours each day.
The company hires four people in full-time positions: two to work the eight-hour first shift and two to work the eight-hour second shift. This means the machine produces the goods it's supposed to for two shifts, meaning 16 hours per day. Hiring an additional two people to work the eight-hour third shift increases the returns of the machine by using it to its maximum capacity, which is 24 hours each day.
From this point on, hiring any extra employees to work the machine will only decrease the machine's efficiency, since the production cannot physically be increased. An auto shop has two technicians that are each capable of changing the oil on 25 cars per day, resulting in a total output of 50 oil changes per day.
They add a new technician and production increases to 75 oil changes per day. They then add a fourth technician, but production only increases to 90 oil changes per day. The reasons can be related to a lack of workspace and equipment to fully accommodate all four technicians or lack of demand. A farmer owns a certain amount of land and can use fixed amounts of seeds, water and human labor. However, they can increase the amount of fertilizer they use to increase production yield.
As the amount of fertilizer used increases, the same land will produce a better crop than before. After a certain point, however, adding more fertilizer will not result in the same increase in output as too much fertilizer could damage the crops. Popular Courses. Financial Ratios Guide to Financial Ratios. Key Takeaways The law of diminishing marginal returns states that adding an additional factor of production results in smaller increases in output.
After some optimal level of capacity utilization, the addition of any larger amounts of a factor of production will inevitably yield decreased per-unit incremental returns.
For example, if a factory employs workers to manufacture its products, at some point, the company will operate at an optimal level; with all other production factors constant, adding additional workers beyond this optimal level will result in less efficient operations.

Related Terms Law of Diminishing Marginal Productivity Explains the Decay of Cost Advantages The law of diminishing marginal productivity states that input cost advantages typically diminish marginally as production levels increase.
What Is the Isoquant Curve? The isoquant curve is a graph, used in the study of microeconomics, that charts all inputs that produce a specified level of output. Demand For Labor The demand for labor describes the amount and market wage rate workers and employers settle upon at any given moment. It is also known as a marginal value product.
It follows the law of diminishing returns, eroding as output levels increase. Why Minimum Efficient Scale Matters The minimum efficient scale MES is the point on a cost curve when a company can produce its product cheaply enough to offer it at a competitive price.
