Definitions:

Isoquant

A curve that represents all combinations of inputs that produce the same level of output in production theory.

Marginal Product

The additional output resulting from a one-unit increase in the use of a variable input, holding all other inputs constant.

Average Product

The Average Product is an economic term that describes the output per unit of input, calculated by dividing total product by the number of units of input.

Diminishing Returns

The principle where the increase in the quantity of input will, after a certain point, yield progressively smaller increases in output.
