Formula for Inflation with Adaptive Expectations

Policymaker's Incentive to Counter a Negative Demand Shock

An economy experiences a sustained, severe decline in aggregate demand, causing the unemployment rate to rise significantly and the inflation rate to fall from its long-run average of 4% to 2% in the first year. If this high level of unemployment persists into the second year, what is the most likely outcome for the inflation rate in that second year, and why?

An economy is hit by a sustained negative aggregate demand shock, causing a recession. Arrange the following events to correctly describe the resulting disinflationary process.

Analyzing a Disinflationary Trend

The Mechanics of a Disinflationary Process

In the disinflationary process that results from a sustained negative demand shock, the economy's adjustment is characterized solely by a movement downward along a single, stable short-run Phillips curve.

Sustained vs. Temporary Economic Shocks

Match each component of the disinflationary process that follows a sustained negative demand shock with its correct description.

In the disinflationary process that follows a sustained negative demand shock, the observed lower rate of price increases causes individuals and firms to revise their ____ downward, which is the direct cause of the downward shift in the short-run Phillips curve.

An economy experiences a persistent and severe decline in aggregate demand, leading to a prolonged recession. The central bank, expecting a rapid self-correction, decides not to intervene with expansionary policy. In the first year of the recession, the inflation rate falls from its stable rate of 3% down to 1%. Given the sustained nature of the recession and the central bank's inaction, what is the most likely outcome for the inflation rate in the following year?
