Definitions:

Isoquants

Curves that represent combinations of different inputs that produce the same output level, used in production theory.

Marginal Productivity

The increase in output resulting from a one-unit increase in the input of a particular resource, while holding inputs of all other resources constant.

Output Constant

A fixed amount of production that does not change with the levels of input.

Isocost Line

A graph representing all combinations of inputs which cost the same total amount.
