Key Terms
Average fixed cost: Fixed cost per unit AFC= TC/Q

Average variable cost: Variable cost per unit; AVC = TVC/Q
Diminishing marginal productivity: Falling MP as more units of a variable factor are added to a fixed factor
Long run production: Time period where all factor inputs are variable
Marginal cost: MC is change in total cost from supplying one extra unit
Short run production: Time period when at least one factor input is fixed
Sunk cost: A cost that cannot be recovered in a business closes down or leaves an industry
Total cost: TC = total fixed cost + total variable cost
Total fixed cost: Costs that do not depend on the level of output in the short run
