Mechanism of Expectations-Driven Inflation

Anchored Inflation Expectations

Consider two distinct economic scenarios. In Scenario 1, a sudden and temporary disruption to global supply chains causes a one-time increase in the price of imported goods. In Scenario 2, a central bank makes a credible announcement that it will tolerate a higher rate of price increases in the future, leading workers and firms to anticipate this higher rate in their wage and price-setting decisions. How do these two scenarios fundamentally differ in their effect on the economy's underlying trade-off between inflation and unemployment?

Analyzing Inflationary Pressures

The Self-Fulfilling Nature of Inflation Expectations

Consider an economy where, following a decade of price stability, a one-time, unexpected increase in energy prices causes the overall price level to rise for a single year before returning to its previous stable trend. This temporary price increase is best characterized as a fundamental, upward shift in the economy's underlying inflation-unemployment trade-off, driven by a lasting change in public expectations.
