What you’ll learn

  1. A Rising Price LevelDefine inflation vs relative prices and introduce CPI and real values.Inflation is a broad, sustained rise in prices. Indexes estimate it; real values adjust nominal numbers for purchasing power.
  2. Demand, Supply, and ExpectationsExplain demand-pull, cost-push, and sticky expectations.Spending pressure, input shocks, and expected inflation interact; credibility helps anchor beliefs.
  3. Money, Policy, and Limits of MetaphorsConnect money, rate policy, and hyperinflation as extremes without giving advice.Long-run money stories matter; policy rates are the usual tool; hyperinflation is institutional breakdown at scale.
