1. The substitution effect describes howa. an increase in income causes buyers to

purchase different productsb. the opportunities for minorities are

affected by affirmative action’s policiesc. the additional satisfaction from each

additional unit of the product consumed in a given time period decreases

d. a price increase creates incentives for buyers to seek alternatives

D. The substitution effect occurs when the price of a good falls, consumers will substitute it for other goods, which are now relatively more expensive.

3

2. If the income effect is the only economic principle operating, when price increases the quantity

a. demanded of a normal good will increaseb. demanded of an inferior good will increasec. demanded of a complement will increased. demanded of any good will decrease

B. The income effect occurs when a fall in the price of a good increases consumer’s real income, making them more able to purchase all goods, so the quantity demanded increases.

4

3. Total utility a. has all of the following as correct responses

b. decreases as price increasesc. can be used to compare two people’s

experiencesd. depends on individual attitudes and

preferences

D. Utility is the satisfaction received from consuming a good or service or a collection of goods and services; satisfaction, sense of wellbeing.

5

4. A word that can be substituted for utility is a. cost

b. pricec. satisfactiond. income

C. Same as previous answer.

5. Economic analysis of utility a. is used to teach consumers how to spend

their incomeb. is used to explain how tastes develop and

why different people have different tastesc. is used to measure utility objectively and to

compare the utilities of different peopled. assumes that tastes are given and that they

are also stable

D. Economists have little to say about the origin of tastes or why tastes seem to differ across individuals - they simply assume that although people have different tastes, an individual’s tastes are not changing all the time.

7

6. Marginal utility is the a. overall satisfaction from consuming a goodb. additional satisfaction from consuming one

more unit of a goodc. average satisfaction from consuming a

goodd. the change in satisfaction from consuming

1% more of a goodB. The word margin always means a change or

the last increment. Marginal utility is the change in total utility derived from a one unit change in consumption of a good.

8

7. Total utility can be measured asa. the sum of all marginal utilitiesb. the sum of all average utilitiesc. the total revenue spent on goods and

servicesd. the price of a product

A. Total utility is the total satisfaction a consumer derives form consumption.

9

8. The basic hypothesis of utility theory states that as more of a commodity is consumed during a given period of time,

a. total utility and marginal utility will both decreaseb. total utility and marginal utility will both

increasec. total utility will increase but marginal

utility will eventually decreaseC. Economists assume that the economy is

made up of people who would rather have more of something then less. However, beyond a certain point, each additional unit of a good brings less and less satisfaction to a person.

10

9. Newspaper vending machines illustrate that newspaper publishers believea. the average utility of two identical

newspapers is zero or lessb. the total utility from two identical

newspapers is zero or lessc. the marginal utility of a second identical

newspaper is zero or lessd. the marginal utility of a second identical

newspaper is greater than the marginal utility of the first newspaper

C. If this were not the case people would take more than one newspaper from the machine.

11

10. Using numerical values to measure utility a. is essential, and is the only way to analyze

utilityb. shows the relationship between total utility

and marginal utility in a simple mannerc. allows us to compare utility between

different consumersd. is only possible in a world without scarcity

B. A unit measure of utility is called a Util. The first hamburger bought may bring you 10 utils worth of satisfaction, a second hamburger may only bring you 7 utils etc.

12

11. Negative marginal utility means that a. total utility is also negative

b. marginal utility is increasingc. the price of the product is increasing as

additional units are consumedd. total utility is decreasing as additional

units are consumed

D. If you were forced to eat ten hamburgers beyond a certain amount, say four, each hamburger consumed will inflect pain instead of pleasure.

13

12. Given the following total utility schedule, what is the marginal utility of the third unit consumed?

14. If a good is offered to a rational individual for free, she will

a. accept unlimited quantities of the good each time periodb. stop consuming it when its marginal utility

begins to increasec. stop consuming it when its marginal utility

begins to diminishd. stop consuming it when its marginal utility

equals zero

D. When the marginal utility is zero a consumer receives no satisfaction from consuming that last unit.

16

15. As long as scarcity exists,a. product prices play no role in utility

maximizationb. income plays no role in utility maximizationc. income and product prices must both be

considered in utility maximizationd. consumers maximize utility by consuming

all products until their marginal utility is zero

C. The reason why a good has a price is that there is not enough of it to go around to everyone who wants it for free. The one’s who receive the good are those who want it the most and have the money to pay for it.

17

16. In terms of utility theory, equilibrium in the real world means that

a. households are consuming as much of every commodity as they would likeb. households have spent their incomes in

such a way that their overall satisfaction is maximized

c. households have spent their incomes in such a way that their marginal utility is zero for every product consumed

B. Economists always assume that consumers will make choices to maximize their total utility.

18

17. On a hot summer day, an individual decides to eat three ice-cream sundaes at a price of $2 each. If he is a utility-maximizer, what is the value of the marginal utility of the fourth sundae to him that day?

a. less than $2b. more than $2c. zerod. negative

A. This means that the person places a greater value on his $4 than he does on a fourth sundae.

19

18. The utility-maximizing combinations of goods occurs whena. the marginal utility of each good is equalb. the total utility of each good is equalc. the quantity consumed of each good is

equald. the marginal utility per dollar spent on

each good is equal

D. If a consumer can increase his total utility by purchasing less of one good and more of another good, he will do so. This person will have no incentive to change his spending priorities if by so doing will not increase his total utility.

20

19. As a utility-maximizer, you would be willing to pay twice as much for Good X as you pay for Good Y if

a. Goods X and Y are substitutes for each otherb. you purchase twice as much of Good Y as

you do of Good Xc. you spend equal amounts on both goodsd. the last unit of Good X you buy is twice as

satisfying as the last unit of Good Y you buy

D. How much you are willing to spend on a good is determined by how much satisfaction you think you will derive from the good.

21

20. A utility-maximizing consumer buys only CDs and books. After all of his income is spent, he finds that the last CD he bought gave him 60 units of satisfaction, and the last book he purchased gave him 30 units of satisfaction. CDs cost $12 each and books cost $5 each. Which statement is true? a. he should buy fewer CDs and fewer booksb. he should buy more CDs and more booksc. he should buy more CDs and fewer booksd. he should buy more books and fewer CDs

D. The last CD has twice as much utility than the last book, however, the last CD is priced more than double the last book.

22

21. Johanna often buys her favorite soft drink every week. She will buy cans up to the last can where her marginal utility is greater than the price (MU>P).a. Trueb. False

A. TRUE As long as her MU > P she is placing a greater value on the can of soda pop than she is the money she has to pay for the soda pop. At the first unit where her MU < P she will not buy that can of pop because she will not give up something of greater value to receive something of lower value.

23

22. To derive a consumer’s demand curve using utility analysis, note the effect of the consumer’s utility-maximizing combination of goods purchased when

a. the consumer’s marginal utilities changeb. the consumer’s income changesc. the consumer’s tastes and preferences

changed. the price of a product changes

D. A demand curve shows how many units will be demanded at various prices. Therefore, what is pertinent here is a change in price.

24

23. The law of demand states that a. quantity demanded is inversely related to

priceb. quantity demanded is directly related to

incomec. marginal utility is inversely related to

quantity consumedd. demand curves are linear

A. The word inverse here means “moves in the opposite direction.” As the price of a good increases consumers will tend to buy fewer units and vice versa.

25

24. In animal experiments examining implications of the law of demand, researchers

a. discovered that the law of demand does not apply to animal behaviorb. were unable to establish “prices”, so could

not answer the question of whether the law of demand applies to animal behavior

c. proved that rats will not drink root beerd. found that animal consumption choices are

consistent with the law of demand

D. Even animals make decisions, eat or not to eat, stay inside or go outside etc.

26

25. Along a consumer’s demand curve, price reflectsa. the costs of productionb. the dollar value of the total utility from the

goodc. the dollar value of the marginal utility of

each additional unit of the goodd. the maximum quantity which could be

purchased, given incomeC. Economists derive demand curves by using

marginal utility analysis. The price that a consumer is willing to pay for something is determined by their MU of that last unit.

27

26. Consumer surplus is defined asa. the amount by which quantity supplied

exceeds quantity demanded at the current market price

b. the amount by which quantity demanded exceeds quantity supplied at the current market price

c. the difference between the maximization amount that a consumer is willing to pay for a given amount of a good and the amount that the consumer actually pays

C. Because the price of identical units of a product is the same at one place at one time, some people will end up with consumer surplus, that is, all consumers are different.

28

27. If you are willing to pay $250 for a certain VCR, but you purchase it on sale for $200, your consumer surplus isa. impossible to determine from the

information givenb. 1/5 = 0.2c. $250d. $50

D. You bought the VCR for less money than you would be willing to pay for it, precisely $50 less.

29

28. When price decreases, consumer surplus a. increases

b. remains constantc. decreasesd. becomes negative

A. In questions like this we always make the “everything else being equal” assumption. Everything else being equal, a person’s consumer surplus will increase as the price of the good decreases.

30

29. Let’s suppose you own a business and you are considering raising the price of your product. If the demand curve of your product faces an inelastic demand curve then the higher price will increase your total revenue.

A. TRUEB. FALSE

A. TRUE This is the definition of elasticity. If you raised your price and the result was a lower revenue then the product would face an elastic demand curve.

31

30. The market demand curve for a product isa. the horizontal sum of the demand curves

for each of the individual brands of the product

b. the horizontal sum of the demand curves of each of the individual buyers in the market

c. the same as the demand curve facing each of the individual sellers in the market

d. the same as the individual demand curve of one of the buyers in the market

B. This is how economists determine the market demand curve for a product.

32

31. Which of the following is not true with regard to consumer surplus?a. consumer surplus reflects the net benefit to

consumers from market exchangeb. consumer surplus is zero if the good is

given away for freec. consumer surplus is used as a measure of

economic welfared. consumer surplus can be used to compare

the effects of different market structures and different tax policies

B. If a good is given away for free when a person would have been willing to pay something for that good, then consumer surplus is positive.

33

32. Consumer surplus exists a. when actual market price is greater than

the equilibrium market priceb. when actual market is less than the

equilibrium market pricec. because producers charge a price that is

greater than the cost of productiond. when consumers pay the same price for

each unit of a good, because the price reflects only the value of the last unit purchased to the consumer

A. This means that there are people paying less for the good than they would be willing to pay

33. Refer to Exhibit 19-1. Consumer surplus at market equilibrium is

a. represented by triangle RPTb. represented by triangle PTKc. represented by triangle RTKd. zero

D. Consumer surplus at T is zero because, as a whole, at this level the quantity demanded exactly equals the quantity supplied. At prices above P there will be some consumers who were willing to pay a higher price but paid a lower price, thus they experience some consumer surplus.

34. A Medicaid experiment in California showed that a nominal fee of $1 charged for doctors’ visitsa. caused beneficiaries to stop going to the

doctor altogetherb. significantly reduced benefits to those

covered by Medicaid without reducing the cost of the program to taxpayers

c. reduced the cost of the program to taxpayers without creating a substantial burden for recipients

C. Society still benefited from the program because at one dollar there was considerable consumer surplus.

37

35. The cost of consumption has two components:a. the substitution effect and the income effectb. the law of demand and the law of

diminishing marginal utilityc. the price effect and the income effectd. the money price and the time price

D. Let’s suppose that you want to see a movie and tickets are selling for $5, which you think is a fair price to see the movie. However, when you get to the theatre the line to get in extends all the way around the corner. Now, all of a sudden, the total price to see the movie is more than just the $5 ticket.

38

36. In most markets, each consumer a. faces the same money price and time price

b. faces different money prices and different time prices

c. faces the same money price but different time prices

d. has the same individual demand curve for the product

C. Wal-Mart may offer low prices, but if I have to drive 50 miles to get to the nearest Wal-Mart store, my time price is higher than someone who lives right next to the store.

39

37. Your willingness to pay additional dollars for time-saving goods depends primarily ona. the opportunity cost of your timeb. your wealth and propertyc. your social statusd. the distance between your home and your

workplaceA. Will you do home repairs yourself or hire

someone to do the repairs? Assuming that the task is a simple one you can do (but time consuming), your decision will be partly based on how much money will you be giving up to do the repairs yourself because you cannot be making money and doing the repairs at the same time.

40

38. Which of the following people would probably be least likely to search the newspaper ads for bargains and clip store coupons?

a. a retired personb. an unemployed personc. a waitress earning $5 an hourd. an attorney earning $100 an hour

D. The attorney’s opportunity cost of spending time clipping coupons is very high compared to someone else who only makes $7 an hour.
