question
Don Keene promotes boxing matches. He makes $6,500 per fight. Which cost is most relevant to a decision as to whether to promote one more fight?
answer
the marginal cost of promoting one additional boxing match
question

answer
$15
question
A firm's total fixed cost equals $2,500. The firm's average fixed cost at 1, 5, and 10 units of output, respectively, will be:
answer
$2,500, $500, and $250
question

answer
Marginal cost is less than average total cost.
question
Luke realizes that his space taxi service is operating in the region of diminishing marginal product. As he provides more taxi service in the short run, what will happen to the marginal cost of providing the additional service?
answer
Marginal cost will increase
question
If the total cost of producing 10 units equals $90, and the average total cost of producing 11 units equals $8.75, then the marginal cost of the eleventh unit produced
answer
is less than the average total cost of producing ten units
question
When economies of scale exist, a decrease in the level of output will lead to
answer
an increase in cost per unit
question
What will pull up/down the average total cost and average variable cost curve?
answer
Marginal cost curve
question
Which of the following is true about perfect competition?
answer
-Since a perfectly competitive seller can sell all he wants at the market price, her demand curve is horizontal at the market price over the entire range of output that she could possibly produce.
-Because perfectly competitive markets have many buyers and sellers, each firm is so small in relation to the industry that its production decisions have no impact on the market.
- Because consumers believe that all firms in a perfectly competitive market sell identical (homogeneous) products, the products of all the firms are perfect substitutes.
- Perfectly competitive markets have easy entry and exit.
-All of the above are true about perfect competition.

question
A profit-maximizing firm in a perfectly competitive market will always produce a quantity of output that:
answer
maximizes the amount by which total revenue exceeds total cost
question
A firm sells grapefruit in a perfectly competitive market at a price of $1.50 per pound. The firm's marginal revenue
answer
equals $1.50
question
If a perfectly competitive firm's marginal revenue was less than its marginal cost
answer
it would contract its output but not raise its price in order to increase its profits
question
Which of the following is true of perfectly competitive firms?
answer
For a perfectly competitive firm, as long as the price derived from expanded output exceeds the marginal cost of that output, the expansion of output creates additional economic profits
question
At the level of output where marginal revenue equals marginal cost, price is less than average total cost but greater than average variable cost. In this instance, a profit-maximizing firm should:
answer
continue operating at that output level in the short term, since total revenue will cover all of the firm's variable costs and some of its fixed costs.
question
When the demand curve is horizontal (straight line) the firm can be classified as
answer
-A price taker
-very small relative to market output as a whole
-producing a homogeneous product
-very small relative to market output as a whole
-producing a homogeneous product
question
When market price falls below AVC (average variable cost) the firm should:
answer
Shut down. Because they cannot cover their variable costs or fixed costs.
question
To maximize profits, a firm should produce the output at the point where:
answer
MC(Marginal Cost)=MR(Marginal Revenue)
question
When price is more than average variable cost, but less then average total cost, the firm should:
answer
keep operating in the short run in order to minimize losses, since price exceeds average variable cost
