Definition and Statement of the Law: The law of diminishing marginal utility describes a familiar and fundamental tendency of human behavior.

Gossen, a German economist, was first to explain this law in 1854.
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.
