In economics, average variable cost (AVC) is a firm's variable costs (labor, electricity, etc.) divided by the quantity of output produced. Variable costs are those costs which vary with output. : where VC = variable cost, AVC = average variable cost, and Q = quantity of output produced. Average variable cost plus average fixed cost equals average total cost: : A firm would choose to shut down if marginal revenue is below average variable cost at the profit-maximizing positive level of output. Producing anything would not generate revenue significant enough to offset the associated variable costs; producing some output would add losses (additional costs in excess of revenues) to the costs inevitably being incurred (the fixed costs). By not producing, the firm loses only the fixed costs. ==See also== *Variable cost *Fixed cost *Cost curve 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Average variable cost」の詳細全文を読む スポンサード リンク
