📄️ What is inflation?
Learn what inflation means, how it affects your money and purchasing power, and why central banks monitor it closely.
📄️ Demand-pull inflation
Learn how excess demand drives up prices when the economy produces less than consumers want, and why it's called 'too much money chasing too few goods.'
📄️ Cost-push inflation
Learn how rising production costs drive prices up independently of demand, including wage increases and commodity price shocks.
📄️ Built-in inflation
Learn how past inflation becomes embedded in expectations and behavior, creating momentum that persists even after original causes disappear.
📄️ The wage-price spiral
Learn how rising wages push up prices, which push up wages again, creating a self-reinforcing cycle that's difficult to break.
📄️ Inflation expectations
Learn how people's expectations about future inflation shape wage demands, prices, and economic behavior—and why central banks prioritize managing them.
📄️ Headline vs core inflation
Learn the difference between headline and core inflation, why the Fed focuses on core, and what each metric tells you about economic conditions.
📄️ Consumer Price Index (CPI)
Learn how the CPI is calculated, why it matters for investments and policy, and how to interpret CPI data releases.
📄️ PCE price index
Understand the Personal Consumption Expenditures price index, the Fed's preferred inflation measure, and how it differs from CPI.
📄️ Producer Price Index (PPI)
Understand the Producer Price Index, what it measures, why it matters, and how it differs from consumer inflation measures.
📄️ Shelter inflation
Understand why housing costs dominate inflation, how shelter is measured in CPI, and what it means for the economy.
📄️ Services vs goods inflation
Understand the difference between services and goods inflation, why they move differently, and what it means for the economy.
📄️ Import Price Inflation
Learn how global prices affect domestic inflation when importing goods from abroad. Currency, tariffs, and supply chains explained.
📄️ Stagflation
Learn what stagflation is, why it occurs, and how the 1970s oil crisis created the worst economic environment for policy. Causes and solutions.
📄️ Disinflation vs Deflation
Learn the difference between disinflation (falling inflation) and deflation (falling prices). Why disinflation helps economies heal and deflation traps them.
📄️ Hyperinflation Mechanics
Understand how hyperinflation erupts: fiscal deficits, currency collapse, and the wage-price spiral. Historical cases and the path from inflation to crisis.
📄️ Deflation Mechanics
Understand how deflation creates economic traps: rising real debt, postponed spending, falling wages. Why escaping deflation is harder than escaping inflation.
📄️ Inflation targeting
Inflation targeting is how central banks use a specific inflation goal to guide monetary policy. Learn how it works, why central banks use it, and what happens when it fails.
📄️ Anchored vs unanchored expectations
Inflation expectations determine how fast inflation actually rises or falls. Anchored expectations mean the public believes inflation will stay near the central bank target; unanchored expectations mean they've lost faith.
📄️ Real vs nominal rates
The nominal rate is what the bank advertises; the real rate is what you actually earn after inflation. Learn why the difference matters for savers, borrowers, and policymakers.
📄️ Fisher's equation
Fisher's equation is the mathematical relationship between nominal interest rates, real interest rates, and inflation. It's the foundation for understanding how inflation affects borrowing and saving.
📄️ Inflation as redistribution
Inflation redistributes wealth from savers and creditors to borrowers and debtors. Learn who wins and loses when prices rise, and why this matters for inequality and financial stability.
