b. False Average total cost is equal to marginal cost where marginal cost is at a minimum.
b. False If the long-run average cost curve slopes upward over some range of output, then the firm is experiencing increasing returns to scale over that range of output.
b. False The point of inflection of the short-run total variable cost function corresponds to the level of output where marginal cost is at a minimum.
b. False If marginal cost is greater than average total cost, then average total cost is rising.
b. False The vertical distance between the short-run average total and average variable cost curves is equal to marginal cost.
b. False The minimum short-run average total cost occurs at a level of output that is greater than that at which average variable cost is at a minimum.
b. False The slope of a ray drawn from the origin to any point on a total cost curve is equal to average total cost at that point.
b. False If a ray that is drawn from the origin to a point on a total cost curve is tangent to the total cost curve, then its slope is equal to the minimum average total cost of production.
b. False The point at which the marginal product of a variable input is at a maximum corresponds to the point at which marginal cost is at a maximum.
b. False The level of output at which the average product of a variable input is at a maximum corresponds to the level of output where short-run average total cost is at a minimum.
b. False All costs are variable costs in the long run.
b. False The long-run total cost curve is derived from the firm's expansion path.
b. False The long-run average cost curve is tangent to the lowest points on all possible short-run average total cost curves.
b. False Long-run average cost slopes downward over a range of output where a firm experiences decreasing returns to scale.
b. False If long-run marginal cost is greater than long-run average cost, then the firm is experiencing decreasing returns to scale.
b. False Long-run marginal cost is equal to short-run marginal cost at the level of output where the corresponding short-run average total cost curve is tangent to the long-run average cost curve.
b. False Industries where the long-run average cost curve has a positive slope over a wide range of output are referred to as natural monopolies.
b. False Industries in which small and large firms coexist successfully have long-run average cost curves that are nearly horizontal. T
b. False Firms that produce more than one type of product cannot benefit from economies of scope.
b. False Learning curves slope upward.
b. False If a learning curve is represented by C = aQ, then b > 0.
b. False The brain drain refers to the emigration of highly skilled workers from their home countries.
b. False Cost-volume-profit analysis is used to determine the profit-maximizing level of output.
b. False The contribution margin per unit is equal to price minus short-run average variable cost.
b. False Breakeven output is equal to total fixed cost divided by the contribution margin per unit.
b. False The degree of operating leverage is equal to the ratio of the firm's total fixed cost to total variable cost.
b. False An increase in operating leverage results from the substitution of fixed costs for variable costs.
b. False Economic theory suggests that a cubic function is an appropriate form for an empirical short-run total variable cost curve.
b. False The survival technique is used to estimate short-run total variable cost functions.
b. False Logistics is also referred to as supply chain management.
b. False Just-in-time inventory management and globalization have contributed to the emergence and growth of logistics.
b. False Logistics refers to the rational assessment of supply and demand by consumers.
b. False While it may contribute to cost savings, logistics is not a source of competitive advantage.
b. False Logistics merges a firm’s design and manufacturing functions into a centrally managed unit.
b. False When marginal cost is equal to the average variable cost average variable cost is on the minimum amount?Marginal cost is equal to average variable cost when the average variable cost is minimized. The two dashed lines represent average variable cost AVC and marginal cost MC. They intersect at the lowest point for both. This means that when the AVC is at its lowest point, the marginal cost is also at its lowest.
When the marginal cost is equal to average total cost the average total cost is?The point at which marginal cost equals average total cost (MC = ATC) is known as the break-even point.
When the marginal cost is equal to average cost the slope of the average cost is?By calculus, the slope of a curve is zero at the minimum point. Hence, the slope of the average total cost is zero when the average cost is equal to the marginal cost.
Can marginal cost be equal to average cost?When average cost is neither rising nor falling (at a minimum or maximum), marginal cost equals average cost. Other special cases for average cost and marginal cost appear frequently: Constant marginal cost/high fixed costs: each additional unit of production is produced at constant additional expense per unit.
