Figure 4.14: Causal Chain from Last Year's Inflation to This Year's Inflation

Derivation of the Inflation Formula with Adaptive Expectations

In an economy where wage and price setters form their inflation expectations based on the previous year's inflation rate, suppose the inflation rate last year was 4%. If the economy is currently experiencing a positive bargaining gap of 1.5%, what will be the inflation rate for the current year?

An economy is experiencing a persistent positive bargaining gap, and its participants (workers and firms) form their inflation expectations based on the inflation rate of the previous period. Arrange the following events to illustrate the correct causal chain that explains how inflation from one period influences the next.

Explaining Inflation Dynamics

Determinants of Current Inflation

In an economic model where expectations about future price increases are based on the most recently observed rate of price increases, the presence of a zero bargaining gap will cause the rate of price increases to immediately fall to zero.

Match each component of the inflation process with its specific role in determining the current period's inflation rate, assuming expectations are formed based on recent past experience.

The Dynamics of Persistent Inflation

In an economy where inflation expectations are based on the previous period's inflation rate, for the current inflation rate to be the same as the previous period's rate, the bargaining gap must be ____.

Policy Impact on Inflation Dynamics

An economy's inflation rate over four consecutive years is shown below. Assume that economic agents in this economy form their inflation expectations based on the actual inflation rate of the previous year.

• Year 1: 2.0%
• Year 2: 3.5%
• Year 3: 5.0%
• Year 4: 5.0%

Based on this data, which statement most accurately describes the state of the bargaining gap from the beginning of Year 2 to the end of Year 4?
