1. For each of the following economies, select the term—inflation, deflation, or

disinflation—that best describes what the economy is experiencing. (LO1)

March April May

Annual percent change in the

consumer price index

Economy A -1.5% -1.5% -1.5%

Economy B 3.2% 2.3% 0.8%

Economy C 1.5% 1.5% 1.5%

Answer:

Economy A is experiencing deflation, as the price level is falling each period.

2. As a monetary policymaker, would you be more concerned if the aggregate price

level were persistently rising by 2 percent or persistently falling by 1 percent?

Explain your answer. (LO3)

Answer: The deflation scenario, where the price level is falling, should be of more

concern, as conventional monetary policy tools are less effective in the face of

deflation. For example, assuming the effective lower bound on nominal interest rates

Data Exploration

1. Are long-term inflation expectations “well anchored?” Using monthly data since

2003, plot a measure of long-term inflation expectations based on the difference

between the yields on a five-year Treasury bond (FRED code: GS5) and a five-year

Treasury Inflation Protected Securities (TIPS) bond (FRED code: FII5). What do you

conclude? How did the financial crisis of 2007-2009 affect the measure? (LO1)

Answer: Based on this measure, long-term inflation expectations were reasonably

consistent with the Fed’s 2-percent inflation target for the decade though mid-2013,

and have drifted down a bit since that time. The key exception was during the

2. Is investment sensitive to the real interest rate? Plot since 1990 a measure of the real

interest rate – based on the difference between Moody’s Baa corporate rate (FRED

code: BAA) and a survey of expected inflation (FRED code: MICH) – and (on the

right scale) the share of investment (FRED code: GPDIC1) in real GDP (FRED code:

GDPC1). Explain the cyclical pattern. (LO2)

Answer: The data are plotted below, where falling real interest rates through the

1990s were associated with rising capital investment. Note that during the recession

of 2001, investment fell as the real interest rate rose. Falling rates again saw rising

3. How sensitive is private investment to risk? Plot since 2004 the share of real gross

private domestic investment (FRED code: GPDIC1) in real GDP (FRED code:

GDPC1) and (on the right scale) a measure of anticipated stock market volatility

(FRED code: VIXCLS). Explain the pattern. (LO2)

Answer: The data plot below is for a short horizon, but suggests that expectations of

rising stock market volatility (measured on the basis of stock options prices) are

associated with falling capital investment. Firms become cautious about investment if

4. A recession may reflect declines in aggregate demand, aggregate supply, or both. Are

swings in consumer sentiment characteristic of recessions? Plot a measure of

sentiment (FRED code: UMCSENT) and discuss its evolution during the recessions

since 1980? Explain why consumer sentiment is an important example of an

aggregate demand shock. (LO2, LO3)

Answer: Consumption is about 70 percent of U.S. GDP, so swings in household

sentiment about the economy can have a major impact on the timing, depth, and

5. How often are negative supply shocks associated with recessions? Plot on a quarterly

basis since 1971 the real price of oil – measured as the ratio of the nominal spot price

of West Texas intermediate oil (FRED code: OILPRICE) to the U.S. consumer price

index (CPIAUCSL). To extend this measure, add a second line showing the ratio of

West Texas intermediate oil prices (FRED code: MCOILWTICO) to the consumer

price index (CPIAUCSL). (These series will overlap for their common period, so use

the Format option in FRED to plot then with the same color.) Identify recessions that

may have been triggered in part by an oil price shock. (LO4)

O3)

Answer: Sharp increases in the real price of oil preceded several U.S. recent

recessions. The most obvious instances are the recessions that began in 1973, 1979,
