Returns to a factor relates to the behavior of total output as one variable input say labour is varied. It is a short run concept. There are three aspects of returns to a factor.
1. Increasing Returns to a factor,
2. Constant Returns to a Factor, and
3. Diminishing Returns to a Factor.

Diminishing returns to a factor may occur due to following reasons:-
1. Fixity of the factor: As more and more units of the variable factor continue to be combined with the fixed factor, the later gets over-utilized.
2. Imperfect Substitution among Factor: Beyond a certain limit, factors of production can not be substitute for one another e.g. more and more of labour cannot be continuously used in place of additional capital.
