Explain the law of diminishing return Solution Law of diminishing returns is an economic law which states that as one unit of input is increased (all other inputs being constant), the output will increase at an increasing rate intially but a point will eventually be reached when these additions of the input will yield diminishing increases in output. In other words, the output will increase but at a diminishing rate. Let us take an example of a chocolate factory and let the variable input be labor hours. As it can be seen from the above table, earlier as the labor hours increased, the chocolates produced increased at an increasing rate till 5 hours. From the 6th hour of additional labor, the marginal chocolates produced started decreasing which shows that the production increased at a diminishing rate. This is what is stated by the Law of Diminishing Returns.Labor HoursChocolates ProducedMarginal chocolates produced15521163198432135491766314774118828987510892.
