B. the average fixed cost curve must lie above the average variable cost curve.
C. marginal cost must be less than average total cost.
D. total cost must also be declining.
Suppose that a business incurred implicit costs of $200,000 and explicit costs of $1
million in a specific year. If the firm sold 4,000 units of its output at $300 per unit, its
accounting profits were:
A. $100,000 and its economic profits were zero.
B. $200,000 and its economic profits were zero.
C. $100,000 and its economic profits were $100,000.
D. zero and its economic loss was $200,000.
If an industry’s long-run average total cost curve has an extended range of constant
returns to scale, this implies that:
A. technology precludes both economies and diseconomies of scale.
B. the industry will be a natural monopoly.
