How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: State one way inflation affects purchasing power.

Answer: Decreases purchasing power as prices increase. Each dollar buys fewer goods and services as general price level rises.

Flashcard 2: What is 'unanticipated inflation'?

Answer: Inflation that occurs unexpectedly, affecting contracts and plans. Creates greater economic disruption as contracts weren't designed for price changes.

Flashcard 3: Define 'cost-push inflation'.

Answer: Inflation caused by increased costs of production. Supply-side pressures from wages, raw materials, or energy price increases.

Flashcard 4: How can inflation affect interest rates?

Answer: Interest rates often rise to compensate for lost purchasing power. Lenders demand higher rates to maintain real returns during inflationary periods.

Flashcard 5: Identify one cost of deflation.

Answer: Increases real debt burden as the value of money rises. Fixed debt payments become more expensive as money gains value.

Flashcard 6: What are 'menu costs'?

Answer: Costs to firms of changing prices due to inflation. Named after restaurant menus that need frequent price updates during inflation.

Flashcard 7: How does inflation affect pensioners?

Answer: Erodes purchasing power if pensions are not inflation-indexed. Fixed pensions lose real value unless adjusted for price level changes.

Flashcard 8: How does inflation impact long-term contracts?

Answer: Creates uncertainty, complicating contract negotiations. Future payment values become unpredictable, increasing business risk.

Flashcard 9: What is the 'Phillips Curve'?

Answer: Illustrates an inverse relationship between inflation and unemployment. Shows short-run tradeoff between unemployment and inflation rates.

Flashcard 10: Identify one impact of inflation on international competitiveness.

Answer: Can reduce competitiveness if domestic prices rise faster than global prices. Higher domestic costs make exports more expensive relative to foreign competitors.

Flashcard 11: Identify one way governments measure inflation.

Answer: Consumer Price Index (CPI). Tracks price changes in a representative basket of consumer goods.

Flashcard 12: Identify one monetary policy tool to control inflation.

Answer: Adjusting the interest rate. Higher rates reduce money supply and cool inflationary pressures.

Flashcard 13: What is a 'price index'?

Answer: A measure that examines the weighted average of prices of a basket of goods. Statistical tool comparing current prices to a base period benchmark.

Flashcard 14: Identify one effect of unexpected inflation on lenders.

Answer: Lenders lose as the real value of repayments decreases. Fixed loan payments become worth less in real terms when inflation rises.

Flashcard 15: What is 'inflation targeting'?

Answer: A monetary policy strategy aimed at keeping inflation within a target range. Central banks set specific inflation goals, usually around 2% annually.

Flashcard 16: How does inflation affect investment decisions?

Answer: Creates uncertainty, potentially reducing long-term investments. Unpredictable future costs make long-term project planning more difficult.

Flashcard 17: Identify one cost of deflation.

Answer: Increases real debt burden as the value of money rises. Fixed debt payments become more expensive as money gains value.

Flashcard 18: What is 'hyperinflation'?

Answer: An extremely high and typically accelerating inflation rate. Often exceeds 50% monthly, can destroy economies and currencies completely.

Flashcard 19: How does inflation affect the real wage?

Answer: Reduces real wage if nominal wages do not increase with inflation. Purchasing power of wages declines when price increases outpace wage growth.

Flashcard 20: How does inflation impact income distribution?

Answer: Can worsen inequality if wages do not keep pace with price increases. Fixed-income earners suffer most while asset owners may benefit.

Flashcard 21: What is the difference between nominal and real interest rates?

Answer: Real interest rate = nominal rate - inflation rate. Real rate measures actual purchasing power return after inflation adjustment.

Flashcard 22: What is a 'price index'?

Answer: A measure that examines the weighted average of prices of a basket of goods. Statistical tool comparing current prices to a base period benchmark.

Flashcard 23: What is 'deflation'?

Answer: A decrease in the general price level of goods and services. Opposite of inflation, where general price levels fall over time.

Flashcard 24: What is 'deflation'?

Answer: A decrease in the general price level of goods and services. Opposite of inflation, where general price levels fall over time.

Flashcard 25: What is 'hyperinflation'?

Answer: An extremely high and typically accelerating inflation rate. Often exceeds 50% monthly, can destroy economies and currencies completely.

Flashcard 26: Identify one effect of unexpected inflation on borrowers.

Answer: Borrowers gain as the real value of repayments decreases. They pay back loans with money that has less purchasing power than borrowed.

Flashcard 27: What is the impact of inflation on tax brackets?

Answer: Brackets may not adjust, leading to higher taxes on nominal gains. Taxpayers pushed into higher brackets despite no real income increase.

Flashcard 28: What is 'stagflation'?

Answer: A period of high inflation combined with stagnation in economic growth. Combines the worst aspects of inflation and economic recession simultaneously.

Flashcard 29: How does inflation impact long-term contracts?

Answer: Creates uncertainty, complicating contract negotiations. Future payment values become unpredictable, increasing business risk.

Flashcard 30: Define 'demand-pull inflation'.

Answer: Inflation resulting from increased demand exceeding supply. Occurs when aggregate demand grows faster than economy's productive capacity.

Flashcard 31: How does inflation impact consumer behavior?

Answer: May lead to increased spending to avoid future price rises. Consumers may accelerate purchases expecting continued price increases.

Flashcard 32: What is 'stagflation'?

Answer: A period of high inflation combined with stagnation in economic growth. Combines the worst aspects of inflation and economic recession simultaneously.

Flashcard 33: How does hyperinflation differ from normal inflation?

Answer: Hyperinflation is an extremely rapid and out of control inflation. Typically defined as monthly inflation rates exceeding 50% or higher.

Flashcard 34: What is 'unanticipated inflation'?

Answer: Inflation that occurs unexpectedly, affecting contracts and plans. Creates greater economic disruption as contracts weren't designed for price changes.

Flashcard 35: What is the impact of inflation on tax brackets?

Answer: Brackets may not adjust, leading to higher taxes on nominal gains. Taxpayers pushed into higher brackets despite no real income increase.

Flashcard 36: What is 'demand-pull inflation'?

Answer: Inflation driven by increased aggregate demand. Excess demand in economy drives prices upward across multiple sectors.
