This means that the law is not applicable in all cases. For this reason, the marginal physical product curve must intersect the maximum point on the average physical product curve. Sum up the main idea The essence of this explanation is that the supply price that sellers are willing and able to receive for a good depends on the production cost. The people are not busy on land throughout the year. If your tenth friend had also exactly £20 on him, then the average would have remained unchanged; £200 divided by 10 is still £20. The arrival of your tenth friend has reduced the average because the amount he added to the total, the marginal, was less than the prevailing average. Causes for the Operation of Law of Diminishing Returns General Application of the Law : The causes for the operation of law of diminishing returns are discussed below: 1.
It may also happen in case of other factors of production. All these factors put a check on the operation of the law of diminishing returns. Even, in case man makes all best efforts but nature is not in favour, the law of diminishing returns is surely to apply. The reason is that in the agricultural sector most of the work is done by hands. In this case the law also applies to societies — the opportunity cost of producing a single unit of a good generally increases as a society attempts to produce more of that good. In the zone A — B there are decreasing returns, and beyond B there are negative returns. Because the marginal product drives changes in the average product, we know that when the average physical product is falling, the marginal physical product must be less than the average.
The law of diminishing returns is a fundamental principle of economics. The marginal cost curve will intersect the average cost curve at its minimum point. This is because after a certain point, the factory becomes overcrowded and workers begin to form lines to use the machines. If there are too few machines, things will run slowly. All three of these are required in combination to convert an input to finished goods and services.
So then, if he has 1,000 acres, he will use 1,000 small cans, which we will assume to be 500 large cans of fertilizer per 1,000 acres. As you add another agent, the service level may improve because the agents aren't overwhelmed and they don't miss calls. The maximum profit can be attained if marginal cost is equal to marginal revenue. In other words, we are dealing with the output per worker, on average. In addition, with the help of graph of law of diminishing returns, it becomes easy to analyze capital-labor ratio. If your tenth friend had had £30 on him, the new total would have been £210, and the new average would have been £210 divided by 10, which is £21. The second worker adds a further 8 units, so the total is now 13 5 + 8 , and so on.
Diminishing returns are due to the disruption of the entire productive process as additional units of labor are added to a fixed amount of capital. The output is measured in physical units like tones, kilograms etc. This curve indicates that as more units of labour and capital are employed, every new unit is producing less marginal production than the preceding one. In such a case, an organization would prefer to hire 20 workers to meet the optimum level of output in case if the labor is available at free of cost, which is not possible. Therefore the law of diminishing returns sets in after the fourth employee is added point A on the chart.
Similarly, increases in workers or in square footage will show a decrease in factory output after some point. This concept can also be applied to consumption. . The variable factor is the labor. In the classic example of the law, a farmer who owns a given acreage of land will find that a certain number of labourers will yield the maximum output per worker. Why is it a law? Therefore, the law of diminishing returns applies in agricultural sector.
First dose of labour and capital applied to land yields more return as compared to second dose. The marginal utility curve has the downward negative slope. But this does not continue for very long. The first worker makes 5 units, so the total is 5. In addition to land, other factors include quantity of seeds, fertilizer, water, and labor. Therefore, the number of workers employed depends on optimum output, product price, and wage rate.
The marginal utility of money declines with richness but never falls to zero. Therefore, it cannot be applied universally. In fact, you can work out the marginals from the totals. This is the reason; it is called universal as it applies everywhere and anywhere. If certain factor becomes fixed, the adjustment of factor of production will be disturbed and the production will not increase at increasing rates and thus law of diminishing returns will apply. This condition known as Negative Returns is widely experienced in practice, but it is not implied by the Law of Diminishing Returns.
