All questions

Question 1

In the short run, if a central bank increases the nominal interest rate and inflation expectations remain unchanged, the real interest rate will

  1. increase, encouraging investment and consumption.
  2. increase, discouraging investment and consumption. (correct answer)
  3. decrease, encouraging investment and consumption.
  4. remain unchanged due to the Fisher effect.
Explanation: The real interest rate is the nominal interest rate minus expected inflation. If the central bank raises the nominal rate while inflation expectations are sticky (unchanged) in the short run, the real interest rate (r = i - πeπ^e) will increase. A higher real interest rate increases the cost of borrowing, which discourages both business investment and household consumption.

Question 2

An investor purchases a conventional 10-year government bond with a fixed nominal yield of 3%. A friend purchases a 10-year Treasury Inflation-Protected Security (TIPS) with a fixed real yield of 1%. If the average annual inflation over the 10 years is 3%, which investor earned a higher real return?

  1. The conventional bond investor, with a real return of 3%.
  2. The TIPS investor, with a real return of 4%.
  3. The TIPS investor, with a real return of 1%. (correct answer)
  4. Both investors earned a real return of 0%.
Explanation: For the conventional bond, the ex-post real return is the nominal yield minus actual inflation: r = 3% - 3% = 0%. For the TIPS, the real return is guaranteed to be 1%, regardless of the inflation rate. Therefore, the TIPS investor earned a higher real return of 1%.

Question 3

A government reduces the tax rate on nominal interest income. If expected inflation and the pre-tax nominal interest rate remain constant, this policy will

  1. increase the after-tax real return on saving. (correct answer)
  2. decrease the after-tax real return on saving.
  3. have no effect on the after-tax real return on saving.
  4. decrease the pre-tax real interest rate.
Explanation: The after-tax real return is calculated as r_after-tax = i(1-t) - π, where i is the nominal rate, t is the tax rate, and π is inflation. If the tax rate (t) is reduced, the term i(1-t), which is the after-tax nominal return, will increase. Since inflation (π) is assumed constant, the entire expression for the after-tax real return will increase. This creates a greater incentive to save.

Question 4

A central bank announces a credible commitment to maintain a 3% inflation target. If the nominal interest rate on 10-year bonds is currently 7%, but market participants expect the central bank to overshoot its target by an average of 1.5 percentage points annually, what real interest rate are investors demanding?

  1. 4%, because investors use the official inflation target when calculating expected real returns
  2. 2.5%, because investors expect actual inflation of 4.5% despite the 3% official target (correct answer)
  3. 3.5%, because investors split the difference between the target and their inflation expectations
  4. 5.5%, because investors add a risk premium to compensate for inflation uncertainty above the target
Explanation: The real interest rate investors demand equals the nominal rate minus their expected inflation. Expected inflation = 3% (target) + 1.5% (expected overshoot) = 4.5%. Therefore, expected real interest rate = 7% - 4.5% = 2.5%. Investors base decisions on their actual expectations, not official targets.

Question 5

A bank offers a certificate of deposit with a nominal interest rate that equals 2% plus the previous year's inflation rate. If inflation rates for three consecutive years are 1%, 4%, and 2% respectively, what nominal and real interest rates does a depositor earn in the third year?

  1. Nominal rate of 6% and real rate of 4%, since the bank rate adjusts for cumulative inflation effects
  2. Nominal rate of 4% and real rate of 4%, since the adjustment mechanism perfectly hedges against inflation
  3. Nominal rate of 6% and real rate of 2%, since the bank rate includes both current and lagged inflation
  4. Nominal rate of 6% and real rate of 4%, since the lagged adjustment creates a mismatch with current inflation (correct answer)
Explanation: In the third year, the nominal rate = 2% + previous year's inflation = 2% + 4% = 6%. The real rate = nominal rate - current inflation = 6% - 2% = 4%. The one-year lag in the adjustment mechanism means depositors earn a higher real return when current inflation (2%) is lower than the previous year's inflation (4%) used to set the nominal rate.

Question 6

During a period of deflation, Country A experiences a -2% inflation rate while maintaining a 1% nominal interest rate. Country B experiences 3% inflation with a 6% nominal interest rate. Which country offers the higher real interest rate, and by how much?

  1. Country A offers a real rate 0% higher than Country B, since both countries have identical real rates of 3% (correct answer)
  2. Country B offers a real rate 0% higher than Country A, since deflation eliminates any real return advantage
  3. Country A offers a real rate 0% higher than Country B, since deflation makes nominal and real rates equivalent
  4. Country A offers a real rate 6% higher than Country B, due to the combined effects of deflation and lower nominal rates
Explanation: Country A's real rate = 1% - (-2%) = 1% + 2% = 3%. Country B's real rate = 6% - 3% = 3%. Both countries offer identical real interest rates of 3%. The deflation in Country A creates a positive real return despite the low nominal rate, while Country B achieves the same real return through higher nominal rates that compensate for inflation.

Question 7

An economy experiences an unexpected surge in inflation from 2% to 6% during a year when the nominal interest rate on government bonds remains fixed at 5%. If investors had initially expected 2% inflation when purchasing these bonds, what is the actual real interest rate earned by bondholders, and how does this compare to their expected real interest rate?

  1. The actual real interest rate is -1%, which is 4 percentage points lower than the expected real interest rate of 3% (correct answer)
  2. The actual real interest rate is 3%, which is 2 percentage points higher than the expected real interest rate of 1%
  3. The actual real interest rate is 1%, which is 2 percentage points lower than the expected real interest rate of 3%
  4. The actual real interest rate is 5%, which equals the nominal rate since inflation expectations were initially met
Explanation: The actual real interest rate = nominal rate - actual inflation = 5% - 6% = -1%. The expected real interest rate = nominal rate - expected inflation = 5% - 2% = 3%. The difference is -1% - 3% = -4 percentage points. Bondholders earn 4 percentage points less in real terms than they expected due to the unexpected inflation surge.

Question 8

Two countries have identical nominal interest rates of 8%, but Country M experiences 3% inflation while Country N experiences 6% inflation. If purchasing power parity holds and exchange rates adjust accordingly, what happens to the real exchange rate between the currencies over time?

  1. Country M's currency appreciates in real terms because its higher real interest rate attracts international capital flows
  2. Country N's currency appreciates in real terms because higher inflation signals stronger economic growth and demand
  3. The real exchange rate remains constant because purchasing power parity adjustments exactly offset inflation differentials (correct answer)
  4. The real exchange rate becomes indeterminate because nominal interest rate equality eliminates arbitrage opportunities
Explanation: Under purchasing power parity, exchange rates adjust to offset inflation differentials, keeping the real exchange rate constant. Country M has a 5% real interest rate (8%-3%) while Country N has a 2% real interest rate (8%-6%). However, PPP ensures that Country M's currency appreciates nominally by the inflation differential (3% annually), exactly offsetting the real interest rate advantage and maintaining real exchange rate stability.

Question 9

A pension fund manager must choose between a 20-year government bond yielding 6% nominal and a 20-year inflation-protected security yielding 2.5% real. Current inflation is 3%, but the fund's actuaries expect inflation to average 4% over the next 20 years. Which choice provides higher expected returns, and what is the key risk trade-off?

  1. The nominal bond provides 0.5% higher expected returns, but exposes the fund to inflation risk that could erode real purchasing power
  2. The inflation-protected security provides 0.5% higher expected returns, while eliminating inflation risk entirely for better liability matching (correct answer)
  3. The nominal bond provides 1.5% higher expected returns, but creates duration risk that increases with inflation volatility over time
  4. Both securities provide identical expected real returns of 2.5%, but differ in their exposure to interest rate and inflation risks
Explanation: Expected real return on nominal bond = 6% - 4% (expected inflation) = 2%. Real return on inflation-protected security = 2.5%. The inflation-protected security provides 0.5% higher expected real returns (2.5% vs 2%) while also eliminating inflation risk, making it superior for pension fund liability matching where real purchasing power preservation is critical.

Question 10

An individual invests $10,000 in a certificate of deposit (CD) for one year at a stated nominal interest rate of 4%. The Consumer Price Index (CPI) is 250 at the start of the year and 260 at the end of the year. What is the approximate real rate of return on this investment?

  1. 4.0%
  2. 1.5%
  3. 0.0% (correct answer)
  4. -6.0%
Explanation: First, calculate the inflation rate: π = [(New CPI - Old CPI) / Old CPI] * 100 = [(260 - 250) / 250] * 100 = (10 / 250) * 100 = 4%. Second, use the Fisher equation to find the approximate real interest rate: r ≈ i - π = 4% - 4% = 0%. The nominal return was completely offset by inflation.

Question 11

A corporation is deciding whether to invest in a capital project that is expected to yield a 5% real rate of return. The corporation must borrow funds to finance the project. The nominal interest rate is 8% and the expected rate of inflation is 4%. Which of the following is the correct decision and reasoning?

  1. Invest, because the project's expected real return of 5% is greater than the expected real interest rate of 4%. (correct answer)
  2. Do not invest, because the nominal interest rate of 8% is greater than the project's real return of 5%.
  3. Invest, because the project offers a positive real return, which will increase the firm's profits.
  4. Do not invest, because the project's expected real return of 5% is less than the nominal interest rate of 8%.
Explanation: Investment decisions are based on comparing the expected real return of the project to the expected real cost of borrowing. The expected real interest rate is the nominal interest rate minus the expected inflation rate: r_e = 8% - 4% = 4%. Since the project's expected real return (5%) is greater than the expected real cost of borrowing (4%), the firm should undertake the investment.

Question 12

A saver deposits money in a bank account that pays a nominal interest rate of 6%. The saver is in a 25% marginal income tax bracket, and taxes are levied on nominal interest income. If the inflation rate is 3%, what is the saver's after-tax real rate of return?

  1. 4.5%
  2. 3.0%
  3. 1.5% (correct answer)
  4. 0.75%
Explanation: First, calculate the after-tax nominal interest rate. The nominal rate is 6%, and the tax rate is 25%. The tax paid is 0.25 * 6% = 1.5%. The after-tax nominal rate is 6% - 1.5% = 4.5%. Second, calculate the after-tax real rate of return by subtracting inflation from the after-tax nominal rate: 4.5% - 3% = 1.5%.

Question 13

If the nominal interest rate is 5% and the expected inflation rate is 2%, an unexpected increase in the money supply leads to an actual inflation rate of 4%. The ex-post real interest rate is

  1. 1%, and wealth is redistributed from lenders to borrowers. (correct answer)
  2. 3%, and wealth is redistributed from borrowers to lenders.
  3. 1%, and wealth is redistributed from borrowers to lenders.
  4. 3%, and wealth is redistributed from lenders to borrowers.
Explanation: The ex-post (actual) real interest rate is the nominal interest rate minus the actual inflation rate: r = 5% - 4% = 1%. The ex-ante (expected) real interest rate was 5% - 2% = 3%. Because the actual real rate (1%) is lower than the expected real rate (3%), borrowers pay back less in real terms than anticipated, and lenders receive less in real terms. Thus, wealth is redistributed from lenders to borrowers.

Question 14

Suppose you borrow $1,000 for one year at a nominal interest rate of 10%. At the end of the year, you repay $1,100. If the price level has increased by 15% during the year, what is the approximate real interest rate you paid on the loan?

  1. 10%
  2. 5%
  3. -5% (correct answer)
  4. -15%
Explanation: The nominal interest rate (i) is 10%. The inflation rate (π) is 15%. The real interest rate (r) is approximated by the nominal rate minus the inflation rate. r ≈ i - π = 10% - 15% = -5%. The borrower paid back funds that had significantly less purchasing power, resulting in a negative real interest rate, which is beneficial for the borrower.

Question 15

A central bank has its policy nominal interest rate at the zero lower bound (0%). If the economy experiences persistent deflation of 1.5%, what is the real interest rate and how does this affect monetary policy effectiveness?

  1. The real interest rate is -1.5%, which is stimulative to the economy.
  2. The real interest rate is 0%, which is neutral for the economy.
  3. The real interest rate is 1.5%, which is contractionary and difficult for the central bank to lower. (correct answer)
  4. The real interest rate cannot be determined without knowing the expected rate of deflation.
Explanation: When the nominal rate is 0% and there is deflation of 1.5% (inflation = -1.5%), the real interest rate is r ≈ 0% - (-1.5%) = 1.5%. This positive real interest rate discourages borrowing and spending, acting as a drag on the economy (contractionary). It makes monetary policy difficult because the central bank cannot lower the nominal rate further to reduce the real rate.

Question 16

Suppose an economy is experiencing deflation at a rate of 2% per year. If the nominal interest rate for a one-year savings bond is 1%, what is the approximate real interest rate for the holder of the bond?

  1. -3%
  2. -1%
  3. 1%
  4. 3% (correct answer)
Explanation: The real interest rate is approximated by the nominal interest rate minus the inflation rate (r ≈ i - π). Deflation of 2% means the inflation rate is -2%. Therefore, the real interest rate is r ≈ 1% - (-2%) = 1% + 2% = 3%. During deflation, the real return is higher than the nominal interest rate.

Question 17

An entrepreneur borrows funds to start a new business, agreeing to a fixed nominal interest rate of 7% per year. At the time the loan is made, the expected annual rate of inflation is 3%. If the actual rate of inflation over the loan period is 5%, which of the following statements is correct?

  1. The lender benefits because the actual real interest rate is higher than the expected real interest rate.
  2. The borrower benefits because the actual real interest rate is lower than the expected real interest rate. (correct answer)
  3. Neither the borrower nor the lender is affected because the nominal interest rate was fixed by contract.
  4. The borrower is harmed because the purchasing power of their revenue is eroded by the higher-than-expected inflation.
Explanation: The expected (ex-ante) real interest rate was 7% - 3% = 4%. The actual (ex-post) real interest rate was 7% - 5% = 2%. Because the borrower is paying a lower real interest rate than they anticipated, they benefit from the unexpected inflation. Conversely, the lender is harmed because they receive a lower real return than anticipated.

Question 18

Country A has a nominal interest rate of 15% and an inflation rate of 12%. Country B has a nominal interest rate of 5% and an inflation rate of 1%. From the perspective of an international investor making a decision based solely on real returns, which of the following is true?

  1. Country A is more attractive because its real interest rate is 3%.
  2. Country B is more attractive because its real interest rate is 4%. (correct answer)
  3. Country A is more attractive because its nominal interest rate is 10 percentage points higher.
  4. Both countries are equally attractive because the differential between their nominal and real rates is the same.
Explanation: Investment decisions should be based on real interest rates. For Country A, the real interest rate is r_A ≈ 15% - 12% = 3%. For Country B, the real interest rate is r_B ≈ 5% - 1% = 4%. Since the real interest rate in Country B (4%) is higher than in Country A (3%), Country B offers a higher real return and is more attractive to the investor.

Question 19

An investor comparing two investment opportunities finds that Investment X offers a 8% nominal return with expected inflation of 3%, while Investment Y offers a 6% nominal return with expected inflation of 1%. If actual inflation turns out to be 4% for both investments, what are the actual real returns?

  1. Investment X earns 4% real return and Investment Y earns 2% real return, maintaining their relative advantage
  2. Investment X earns 5% real return and Investment Y earns 3% real return, both exceeding their expected real returns
  3. Investment X earns 4% real return and Investment Y earns 2% real return, both falling short of their expected real returns (correct answer)
  4. Investment X earns 2% real return and Investment Y earns 5% real return, reversing their relative advantage completely
Explanation: Investment X actual real return = 8% - 4% = 4% (expected was 8% - 3% = 5%). Investment Y actual real return = 6% - 4% = 2% (expected was 6% - 1% = 5%). Both investments earned 1 percentage point less in real terms than expected due to higher-than-anticipated inflation, but X still outperforms Y by 2 percentage points.

Question 20

A borrower takes a variable-rate loan with a nominal interest rate that adjusts monthly to maintain a constant 2% real interest rate. If inflation rises from 3% to 7% during the loan period, what happens to the borrower's nominal interest payments and real burden of debt?

  1. Nominal payments increase from 5% to 9%, while the real debt burden remains constant at the contracted rate (correct answer)
  2. Nominal payments remain at 5% to protect the borrower, while the real debt burden decreases due to inflation
  3. Nominal payments increase from 5% to 9%, while the real debt burden decreases because inflation erodes the principal
  4. Nominal payments adjust to 4.5% to split inflation costs, while the real debt burden increases due to uncertainty
Explanation: With a constant real rate contract, nominal rate = real rate + inflation rate. Initially: 2% + 3% = 5%. After inflation rises: 2% + 7% = 9%. The borrower's nominal payments increase to maintain the 2% real interest rate. The real burden of debt service remains constant at 2%, but the nominal payment burden increases significantly.
