55: Firm Costs Flashcards
fixed cost
the cost that doesn’t depend on the quantity of output produced (cost of fixed inputs)
variable cost
cost that depends on the quantity of output produced, cost of variable inputs
total cost
fixed + variable cost
marginal cost
the added cost of producing one more unit of output
marginal cost equation
∆TC / ∆Q
graphical representation of marginal cost
slope of total product curve
average total cost equation
TC / Q
AFC + AVC
average fixed cost eq
FC/Q
Average variable cost
VC / Q
things that influence ATC
1) spreading effect
2) diminishing returns effect
spreading effect
larger output means that there is a greater quantity over which fixed cost is spread, reducing ATC
diminishing returns effect
larger output means that more variable costs are required, increasing ATC
minimum cost output
quantity of output at which ATC is lowest, where ATC = MC
