of inflation was
a. 5 percent.

family bought 4 loaves of bread at 50 cents
per loaf and two bottles of wine for $9 per

a. 100.
b. 115.
c. 126.
d. 130.

4. As shown in Exhibit 13-5, the rate of
inflation for Year 2 is
a. 5 percent.
b. 10 percent.
c. 20 percent.
d. 25 percent.
B. A percent increase of decrease between
two numbers is the difference divided by

100 = 10%

inflation for Year 5 is
a. 4.2 percent.
b. 5 percent.
c. 20 percent.
d. 25 percent.
A. A percent increase or decrease between
two numbers is the difference divided by

6. Deflation is a (an):
a. increase in most prices.
b. decrease in the general price level.
c. situation that has never occurred in
U.S. history.

7. Which of the following would overstate the
consumer price index?
a. Substitution bias.
b. Improving quality of products.
c. Neither (a) nor (b).
d. Both (a) and (b).
D. Substitution bias refers to the law of
demand in which people buy less when
the price rises. However, the CPI is
based on a fixed market basket. Since
improving quality is difficult to measure
increases in the CPI overstate inflation.

8. Suppose a typical automobile tire cost $50 in
the base year and had a useful life of 40,000
miles. Ten years later the typical automobile
tire cost $75 and had a useful life of 75,000
miles. If no adjustment is made for mileage, the
CPI would
a. underestimate inflation between the two
years.
b. overestimate inflation between the two
years.
c. accurately measure inflation between the
two years.
d. not measure inflation in this case.
B. Quality changes are difficult to measure.
When the quality of items improves, increases
in the CPI overstate the change in prices.

9. When the inflation rate rises, the
purchasing power of nominal income
a. remains unchanged.
b. decreases.
c. increases.
d. changes by the inflation rate minus one.

B. Real income =
CPI ÷ 100
A larger value for the CPI
decreases nominal
income.

10. Last year the Harrison family earned $50,000. This
year their income is $52,000. In an economy with an
inflation rate of 5 percent, which of the following is

b. The Harrison’s nominal income and real income
have both fallen.
c. The Harrison’s nominal income has fallen, and
their real income has risen.
d. The Harrison’s nominal income has risen, and
their real income has fallen.
D. % change real income 52,000 - 50,000 - 5%,

4% - 5% = -1%

11. If the nominal rate of interest is less than
the inflation rate,
a. lenders win.
b. savers win.
c. the real interest rate is negative.
d. the economy is at full employment.
C. The real rate of interest is negative
because the lender is receiving less money
back, in real terms, than was lent out.

12. Demand-pull inflation is caused by
a. monopoly power.
b. energy cost increases.
c. tax increases.
d. full employment.
D. Demand-pull inflation is caused by an

raising prices.
