What law of diminishing marginal returns?

Answer 1

The law of diminishing marginal returns states that as the input of one factor of production is increased while keeping the amounts of other factors constant, the resulting increase in output will eventually become less proportionate. In other words, after a certain point, each additional unit of input will yield smaller and smaller increases in output. This law suggests that there is a limit to the efficiency gains achieved by adding more of a particular input.
