Definition: Law of diminishing marginal returns â. At a certain point, employing an additional factor of production causes a relatively smaller increase in output. Diminishing returns occurs in the short run when one factor is fixed (e.g. capital)
The law of diminishing returns states that as one input variable is increased, there is a point at which the marginal increase in output begins to decrease, holding all other inputs constant. At the point where the law sets in, the effectiveness of each additional unit of input decreases.
