Definitions:

Returns To Scale

An economic concept describing how the increase in inputs affects the level of output of a production process.

Production Function

A mathematical equation that describes the relationship between inputs and the maximum output that can be produced with those inputs.

Inputs

Resources used in the production process, such as labor, capital, materials, and energy.

Production Isoquant

A production isoquant is a curve that represents all combinations of inputs that yield the same level of output, used in production theory to analyze efficient production.
