marginal product (MP) of any single input is defined as the change in total product resulting from a small change in the amount of that input used. Marginal product first rises as the result of more effective use of fixed inputs, and then falls.
Exhibit 2: Total Product and Marginal Product
As the amount of a variable input is increased, the amount of other (fixed) inputs being held constant, a point ultimately will be reached beyond which marginal product will decline. This is called diminishing marginal product, which stems from the crowding of the fixed input with more and more of the variable input.
A firm never knowingly allows itself to reach the point where the marginal product becomes negative, the situation in which the use of additional variable input units actually reduces total product. In such a situation, there are so many units of the variable input--inputs with positive opportunity costs—actually impair the efficient use of the fixed input.
