Structure Types of cost curves Fixed variable and total cost functions Average fixed, average variable and average cost functions Marginal cost functions Marginal and variable cost functions Marginal and average cost functions Short run and long run cost curves
Structure Types of cost curves – Fixed, variable and total cost functions – Average fixed, average variable and average cost functions Marginal cost functions Marginal and variable cost functions Marginal and average cost functions Short run and long run cost curves
Types of Cost Curves A tota| cost curve(总成本曲线)is the graph of a firm's total cost function A variab| e cost curve(可变成本曲线 is the graph of a firm's variable cost function An average total cost curve(平均成 本曲线) is the graph of a firm's average total cost function
Types of Cost Curves A total cost curve （总成本曲线）is the graph of a firm’s total cost function. A variable cost curve （可变成本曲线 ）is the graph of a firm’s variable cost function. An average total cost curve （平均成 本曲线）is the graph of a firm’s average total cost function
Types of Cost Curves An average variable cost curve (1 均可变成本曲线) is the graph of a firm's average variable cost function An average fixed cost curve(平均固 定成本曲线) is the graph of a firn’s average fixed cost function A marginal cost curve(边际成本曲线 is the graph of a firm's marginal cost function
Types of Cost Curves An average variable cost curve （平 均可变成本曲线）is the graph of a firm’s average variable cost function. An average fixed cost curve （平均固 定成本曲线）is the graph of a firm’s average fixed cost function. A marginal cost curve （边际成本曲线 ）is the graph of a firm’s marginal cost function
Types of Cost Curves How are these cost curves related to each other? How are a firms long-run and short run cost curves related?
