All of the following are ways a business can earn economic profits except
Discover new products.
→
Maximize implicit costs but not explicit costs.
Take above-average risks.
Find new and better methods of production.
To earn economic profits, a business must see opportunities that others have missed, discover new products, find
new and better methods of production, or take above-average risks. A firm will want to minimize costs in order to
maximize profit.

Accounting costs and economic costs differ because
Accounting costs exceed economic costs whenever any factor is not paid an explicit wage.
Accounting costs include implicit costs, and economic costs do not.
→
Economic costs include the opportunity costs of all resources used, while accounting costs include
actual dollar outlays.
Accounting costs include explicit costs, and economic costs do not.
Accounting costs refer to the explicit dollar outlays made by a producer. Economic costs, in contrast, refer to the
value of all costs, both explicit and implicit.

The cost of taxes.

The return on inventory investment.
The cost of rent.

Suppose a firm has an annual budget of $200,000 in wages and salaries, $75,000 in materials, $30,000 in new
equipment, $20,000 in rented property, and $35,000 in interest costs on capital. The owner/manager does not choose to
pay himself, but he could receive income of $90,000 by working elsewhere. The firm earns revenues of $360,000 per
year.
What is the accounting profit for the firm described above?
-$90,000.
→
$0.
$90,000.
$200,000.
Accounting profit is equal to revenue ($360,000) minus explicit costs ($360,000), which is $0.

Many firms.
Identical products.
→

A perfectly competitive firm risks losing all of its customers, who will shop elsewhere, if it increases the price of its

Product price is constant at all levels of output.
Product price decreases as output increases, and demand is elastic.
Product price increases at all output levels.
Because a competitive firm can sell all its output at the prevailing price, its total revenue curve is linear.

As much as it is capable of producing.
The output where the ATC curve is at a minimum.
The output where the marginal cost curve is at a minimum.
If a competitive firm wanted to maximize its total revenue, it would always produce at capacity because the individual

Average total costs are minimized.
Total revenue is maximized.
Marginal revenue is zero.

Marginal revenue is equal to marginal cost.

Refer to Figure 22.3 for a perfectly competitive firm. Which of the following statements is true for this firm between the
prices of $10 and $15?
The firm is experiencing zero economic profits.
The firm is experiencing economic profits because the market price is greater than or equal to the
minimum AVC.
The firm is experiencing economic losses and should shut down.
→
The firm is experiencing economic losses but should continue to produce.
A firm should shut down only if the losses from continuing production exceed fixed costs. This happens when price is
less than average variable cost. When the price is between $10 and $15, price is less than ATC, so the firm is losing
money, but it is losing less than it would if it shut down.
