Definitions:

Long-Run Minimum Cost

The lowest cost at which a firm can produce any given level of output in the long run, when all inputs can be varied.

Average Total Cost Curve

A graph that shows the cost per unit of output at different levels of production, illustrating how average total cost changes with changes in output.

Short-Run

A period in which at least one of a firm's inputs is fixed and cannot be changed.

Average Fixed Cost

The fixed costs of production divided by the quantity of output produced, which decreases as production increases.
