Deck 8: Output,Price,and Profit: The Importance of Marginal Analysis

Question 1

Answer 1

True

Question 2

Answer 2

False

Question 3

Accounting profit is usually smaller than economic profit.

Answer 3

False

Question 4

Price and output decisions are two aspects of the same choice.

Question 5

A small business owner who is earning a positive economic profit,no matter how small,is doing better than if she sold her business and went to work for another firm.

Question 6

A firm that is earning zero economic profit should go out of business.

Question 7

Once a firm has selected a price for its product,quantity is decided by consumers and their demand curves.

Question 8

The addition to total revenue resulting from one more unit of output is called marginal revenue.

Question 9

Economists assume that business firms have many goals,and profit maximization is just one of them.

Question 10

Marginal revenue equals the change in total revenue that is earned by selling one more unit of output.

Question 11

Total revenue cannot be derived from the demand curve or a demand schedule.

Question 12

A firm's total revenue is simply the price of its product multiplied by the quantity sold.

Question 13

It can be shown that average revenue and price are always equal.

Question 14

Marginal,average,and total figures are bound together.If any two are known,the third can be calculated.

Question 15

Economists and accountants have very different definitions of profit.

Question 16

Accounting profit is usually larger than economic profit.

Question 17

Economists and accountants use the same definition of profit.

Question 18

Economists assume that business firms attempt to maximize their profits.

Question 19

A firm's total profit is the difference between its sales and what it pays out in costs.

Question 20

Total revenue is equal to quantity multiplied by average revenue.

Question 21

Marginal cost curves and average cost curves are both purely upward sloping.

Question 22

Average cost can be thought of as the cost per unit.

Question 23

Given total cost and the quantity of output,marginal cost and average cost can be determined.

Question 24

If marginal cost of an additional unit of output is greater than average cost,then average cost will rise.

Question 25

Marginal profit is the slope of the total profit curve.

Question 26

If marginal cost is less than average cost,average cost must fall when more units are produced.

Question 27

Profits will be maximized when the slope of the total revenue curve and the slope of the total cost curve equal zero.

Question 28

Average cost is the cost of producing the next unit.

Question 29

If marginal cost is rising,then average cost must be rising.

Question 30

Total profit is represented by the vertical distance between a total revenue curve and a total cost curve.

Question 31

Marginal revenue is the addition to total revenue resulting from the addition of one unit to total output.

Question 32

Profits will be maximized when the slope of the total revenue curve and the slope of the total cost curve are equal.

Question 33

If total profit is at a maximum,then average profit is zero.

Question 34

Marginal cost is defined by the slope of the total revenue curve.

Question 35

Average cost equals total cost multiplied by the number of units of output.

Question 36

A graph of total profits is always likely to be positively sloped throughout its length.

Question 37

If the average cost of a product is $10 per unit and the price is $5,the firm is losing money.

Question 38

Total cost equals average cost multiplied by the quantity of output.

Question 39

A firm that sells at a price below average cost is losing money.

Question 40

If average cost is falling,then marginal cost must be falling.

Question 41

A firm should use marginal analysis when making a price-output decision.

Question 42

When a firm's fixed costs increase it should raise its prices in order to maximize profits.

Question 43

If the marginal profit of the next unit is negative,the firm should produce more output in order to generate greater profit.

Question 44

Profit is maximized at the output at which marginal revenue equals marginal cost.

Question 45

Marginal profit equals the difference between marginal revenue and average cost.

Question 46

Profit maximization occurs when MC = MR.

Question 47

A firm is generally more interested in marginal profits than in total profits.

Question 48

All business firms should consider their fixed costs in determining the prices they set.

Question 49

Marginal profit is the additional profit that accrues to the firm when the output rises by one unit.

Question 50

If a firm's marginal profit is negative,it should reduce its output level.

Question 51

If marginal profit is zero,then average profit is at a maximum.

Question 52

Profit is maximized at the output at which marginal revenue exceeds marginal cost by the greatest margin.

Question 53

An optimal level of output is one at which marginal profit > 0.

Question 54

A firm that decides to make a price cut assumes that marginal profit is negative.

Question 55

Net benefit is equal to total benefit minus marginal cost.

Question 56

Marginal profit equals the difference between marginal revenue and marginal cost.

Question 57

If marginal profit is zero,then total profit is at a maximum.

Question 58

If total profit is maximized,then marginal cost must equal marginal revenue.

Question 59

The rule of equating marginal benefit with marginal cost is proper for economics,but it does not describe the way in which people make non-economic decisions.

Question 60

A firm should keep producing output as long as the marginal profit is greater than zero,no matter how small it is.

Question 61

Any change in a firm's fixed costs will change its profit-maximizing level of output.

Question 62
