24. What are two related effects that combine to make a consumer able and willing to buy more of a specific
product at a lower price than a higher price? Explain the logic of both effects.
25. A student asserts in class that the income and substitution effects lead to a decrease in the consumption of a
normal good when the price decreases. Do you agree with the statement? Explain using an example.
26. Assume that a person only purchases two goods, food and clothing, and has a fixed budget constraint. Both
goods are normal goods. If the price of food decreases, what will happen to the consumption of clothing
based on the income effect?
27. In a typical month, a family buys six bags of candy bars as snacks when the price of a bag costs $4.00.
When the price of the candy bars falls to $3.00 a bag, the family buys seven bags of candy bars a month.
When the price of a bag of candy bars rises to $6.00, the family buys three bags a month. Answer these
questions: (a) How did the fall in the price affect real income in terms of bags of candy bars? (b) How did
the rise in the price affect real income in terms of bags of candy bars? [Hint: How many bags of candy bars
could the family buy in situation (a) and in situation (b) without changing the amount they spend on candy
bars in a typical month?]
28. How can the utility-maximizing rule be used to explain the substitution and income effect?

29. Discuss the cost of leisure time in industrially advanced countries relative to those in developing countries.
30. A vice president of a company argues that the president of the company should raise workers’ wages if the
president wants less absenteeism. The president says that wages probably should be cut so that the workers
could not afford to miss so much work. Evaluate the two views using the income and substitution effects in
your analysis.
The analysis must be based on the idea that most workers prefer leisure to working for the president of the
company. Therefore, the higher their income, the more leisure they can afford (income effect). On the
31. Use marginal-utility analysis to explain why the growing popularity of iPads over laptop and desktop
computers.
32. Why would an ounce of gold be priced higher than an ounce of coffee beans, even though coffee is
generally considered more essential than gold? Explain the paradox in terms of marginal and total utility.

33. Is the following quotation consistent with the theory of consumer behavior? “The yield on time spent
working increases as the result of economic growth. Productivity per hour rises. This means that the time
allocation which has represented equilibrium at our previous income level is disrupted. The yield on time
devoted to other activities must also be raised. We are aware that time in production becomes increasingly
scarce with economic growth. What we will now claim in addition to this is that changes in the use of time
will occur, so that the yield on time in all other activities is brought into parity with the yield on working
time. In other words, economic growth entails a general increase in the scarcity of time.” (From: Staffan
Linder, The Harried Leisure Class)
34. A person has a basic choice between eating meals at home and eating meals in a restaurant. The cost of the
food that is eaten at home is $10 per meal. The cost of a restaurant meal is $20. It takes two hours to eat a
meal at home (including preparation time and cleanup time). It takes one hour of time to eat a meal in a
restaurant. The marginal utilities of the home meal and the restaurant meal are the same. The person
values time at $12 per hour. What does the theory of consumer behavior suggest the rational consumer will
decide to do: eat at home or in a restaurant? Answer by first excluding the value of time from the decision.
Then include the value of time in the decision.
If time is not a consideration in the cost of a meal, then the marginal utility per dollar of a meal at home is
greater than the marginal utility per dollar of the restaurant meal (MUh/$10 > MUr/$20). The consumer
35. How does the pricing of medical care in the United States affect the quantity consumed?
36. Explain why, in most cases, you would rather receive a gift of $25 cash over receiving a $25 sweater
chosen by your significant other.

37. Meaning well, your grandmother gives you a new wool sweater for your birthday that she knitted herself.
You, however, hate wearing wool. What is the utility problem that you face? What can you do to remedy
the problem?
38. (Last Word) Describe the relationship between raising the marginal cost of crime and the quantity of crime
committed. Explain the implications of this relationship as applied to property crimes.
39. (Last Word) Suppose Billy is determining whether he should steal a movie from Walmart. The cost of the
movie is $25 and the direct cost and the opportunity cost of stealing the movie is zero. There is a 15 percent
chance of getting caught, and caught, a fine of $250 will be charged.
(a) Will Billy steal the movie?
(b) Suppose Billy has a guilt cost of $10. Will Billy steal the movie?
40. (Last Word) Discuss the decision a criminal must make before deciding whether or not to steal.
A criminal, like a consumer, must compare the marginal utility of the good with the price it. The price of
the good, in the case of stealing, is the cost the criminal would bear by stealing the item. The marginal
utility of the good is the value the individual places on the item. The potential costs of stealing include
direct costs (supplies and tools), forgone income from legitimate work opportunities, and guilt costs. If the
criminal is caught he or she may bear additional costs in the form of fines, imprisonment, and shame.

47. Why are indifference curves downsloping?
48. What is the rationale for the slope of an indifference curve in a two-product (A and B) case?
49. Explain two important characteristics of indifference curves for two goods.
First, indifference curves are downsloping because both goods will yield utility for the consumer. Because
total utility is constant for each indifference curve, the consumption of more of one good would increase
total utility and this must be offset by the decrease in the amount consumed of the other good. More utility
is derived from the consumption of one good; less utility is obtained from the other good. This inverse
relationship produces the downward (negative) slope of the indifference curves.
