Quiz: Inflation and the Business Cycle

Test your understanding of how inflation is measured, why prices rise, and how economic cycles work.

1. What is inflation?

  1. A one-time increase in the price of a single product
  2. A sustained increase in the general price level of goods and services over time
  3. The total amount of money in an economy
  4. A decrease in the unemployment rate
Show Answer

The correct answer is B. Inflation is a sustained increase in the general price level, meaning most prices are rising over time, not just a single item. A temporary spike in gas prices due to a hurricane is not inflation; it is a supply shock to one product. When inflation occurs, each dollar buys fewer goods and services, reducing purchasing power.

2. The Consumer Price Index (CPI) measures inflation by tracking changes in the cost of what?

  1. All products sold in the United States
  2. Only luxury goods and services
  3. A representative "basket" of goods and services that typical consumers buy
  4. Stock market prices
Show Answer

The correct answer is C. The CPI tracks the prices of a "market basket" of goods and services that represents typical consumer spending. The Bureau of Labor Statistics surveys households to determine what Americans actually buy and weights each category by its share of spending. Housing (33%) carries the most weight, followed by transportation, food, and medical care.

3. When the economy is booming and consumers have lots of money to spend but production cannot keep up, the resulting inflation is called what?

  1. Cost-push inflation
  2. Deflation
  3. Stagflation
  4. Demand-pull inflation
Show Answer

The correct answer is D. Demand-pull inflation occurs when aggregate demand exceeds what the economy can produce, described as "too much money chasing too few goods." This often happens during economic booms when employment is high, interest rates are low, or government stimulus puts extra money in consumers' hands. Prices rise because buyers bid up prices competing for limited output.

4. If the CPI was 250 last year and is 260 this year, what is the inflation rate?

  1. 10%
  2. 260%
  3. 4%
  4. 2.6%
Show Answer

The correct answer is C. The inflation rate is the percentage change in the CPI: (260 - 250) / 250 x 100 = 4%. This means prices rose by 4% over the year. The CPI index number itself (260) tells you prices are 2.6 times higher than the base period, but the inflation rate measures the change from one year to the next, not the cumulative change.

5. Deflation (falling prices) sounds like good news for consumers. Why do economists consider it dangerous?

  1. Because it makes exports cheaper
  2. Because consumers and businesses delay purchases waiting for even lower prices, reducing economic activity
  3. Because it automatically raises interest rates
  4. Because it only affects luxury goods
Show Answer

The correct answer is B. Deflation creates a vicious cycle: when prices are falling, consumers and businesses delay purchases because things will be cheaper tomorrow. This reduces spending, which reduces business revenue, leading to layoffs and further reduced spending. Deflation also increases the real burden of debt, since borrowers must repay loans with money that is worth more. Japan experienced a prolonged deflationary period that stunted its economy for decades.

6. If your paycheck stays at $1,000 per month but inflation is 5%, what has happened to your purchasing power?

  1. It increased by 5%
  2. It stayed the same because your pay did not change
  3. It decreased because the same dollars now buy fewer goods
  4. It doubled due to compounding
Show Answer

The correct answer is C. Purchasing power is the quantity of goods and services your money can buy. With 5% inflation, prices are 5% higher, so your $1,000 buys roughly 5% less than before. If wages do not keep up with inflation, workers experience a real pay cut even though their nominal (dollar) wage has not changed. This is why economists distinguish between nominal and real income.

7. Which phase of the business cycle is characterized by declining GDP, rising unemployment, and falling consumer confidence?

  1. Expansion
  2. Peak
  3. Recession
  4. Trough
Show Answer

The correct answer is C. A recession is officially defined as a significant decline in economic activity lasting more than a few months, visible in GDP, employment, income, and other indicators. During recessions, businesses cut production, lay off workers, and investment drops. Consumer and business confidence falls, creating a negative feedback loop that can deepen the downturn until the economy hits a trough and begins recovery.

8. Stagflation is an unusual economic condition that combines what two problems?

  1. High growth and high unemployment
  2. Deflation and high employment
  3. Stagnant economic growth (or recession) combined with high inflation
  4. Low interest rates and high government spending
Show Answer

The correct answer is C. Stagflation combines economic stagnation (slow growth, high unemployment) with high inflation. This is particularly troubling because the typical policy solutions conflict: stimulating the economy to reduce unemployment can worsen inflation, while fighting inflation can worsen unemployment. The US experienced stagflation in the 1970s due to oil price shocks and loose monetary policy.

9. Rising oil prices cause production costs to increase across many industries, leading to higher consumer prices. This type of inflation is called what?

  1. Cost-push inflation
  2. Demand-pull inflation
  3. Deflation
  4. Hyperinflation
Show Answer

The correct answer is A. Cost-push inflation occurs when rising production costs force businesses to raise prices. An oil price spike increases transportation, manufacturing, and energy costs across the economy. Unlike demand-pull inflation (caused by excess spending), cost-push inflation originates from the supply side. Supply chain disruptions and rising wages are other common triggers.

10. Why is moderate inflation (around 2%) generally considered healthier than zero inflation?

  1. Because it helps the government collect more taxes
  2. Because it gives central banks room to lower real interest rates during recessions and encourages spending over hoarding
  3. Because it benefits only wealthy investors
  4. Because it makes imports cheaper
Show Answer

The correct answer is B. Moderate inflation gives central banks flexibility to set negative real interest rates during downturns (if inflation is 2% and the nominal rate is 0%, the real rate is -2%, which stimulates borrowing). Moderate inflation also encourages spending and investment today rather than hoarding cash. With zero inflation, the economy risks tipping into deflation, which is much harder to escape.
