This law of diminishing marginal utility is the counterpart of the law of diminishing marginal returns. The law of diminishing marginal utility is similar to the law of diminishing returns which states that as the amount of one factor of production increases as all other factors of production are held the same, the marginal return extra output gained by adding an extra unit decreases.

In economics, the law of diminishing returns states that, as quantities of one variable factor are increased, while other factor inputs remain constant, all things being equal, a point is reached beyond which the addition of one more unit of the variable factor will result in a diminishing rate of return and the marginal physical product. For the highly competitive firms, the marginal revenue is constant, and the company can produce more outputs until the marginal revenue is equivalent to the cost of producing another unit of the commodity marginal cost.
If units of a resource are added to a fixed proportion of other resources, eventually marginal output will decline.

If the techniques of production undergo a change, in that case the efficiency of production would increase. The law of diminishing returns states that each additional input will less and less output as more are added. Generally, laws of returns to scale refer to an increase in output due to increase in all factors in the same proportion. Total product tells the amount of output produced for each quantity of a variable input. This law only applies in the short run because, in the long run, all factors are variable.
Diminishing marginal returns occur when the marginal product of an additional worker is less than the marginal product of the previous worker. Strictly defined, this refers to a situation faced by.
