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.
The Law of Diminishing Marginal Returns 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 occur in the short run when one factor is fixed (e.g. capital) If the variable factor of production is increased (e.g. labour), there comes a point where it will become less productive and therefore there will eventually be a decreasing marginal and then average product.
