举一反三
- If, in long run equilibrium, the competitive price of some good is $16.67, then, for each and every firm in the industry, A: marginal cost > average cost = $16.67. B: marginal cost < average cost = $16.67. C: $16.67 = marginal cost = average cost. D: $16.67 = marginal cost > average cost.
- In the long run Firm A incurs total costs of $1,200 when output is 30 units and $1,600 when output is 40 units. Firm A exhibits_________. A: constant returns to scale because average total cost is constant as output rises B: diseconomies of scale because total cost is rising as output rises C: economies of scale because average total cost is falling as output rises D: diseconomies of scale because average total cost is rising as output rises
- When marginal cost is less than average cost,
- A competitive firm maximizes profit by choosing the quantity at which ( ) A: average total cost is at its minimum. B: marginal cost equals the price. C: average total cost equals the price. D: marginal cost equals average total cost.
- In short run the shutdown point is that point at which A: price equals marginal cost. B: average fixed cost equals marginal cost. C: average variable cost equals marginal cost. D: average total cost equals marginal cost.
