Definitions:

Implicit Cost

The monetary income a firm sacrifices when it uses a resource it owns rather than supplying the resource in the market; equal to what the resource could have earned in the best-paying alternative employment; includes a normal profit.

Law of Diminishing Returns

The economic principle stating that as one input variable is increased, there is a point at which the marginal gain in output begins to decrease, holding all other inputs constant.

Diseconomies of Scale

Diseconomies of scale occur when a firm's costs per unit increase as the scale of its output increases, often due to inefficiencies that arise from managing a larger organization.

Average Fixed Costs

Costs that do not change with the level of output and are spread over the units of output, thus decreasing per unit as production increases.
