Condition for Falling Inflation under Adaptive Expectations

Inflation Dynamics in a Booming Economy

An economy's inflation rate last year was 3%. This year, the bargaining gap is +2%. If economic agents form their inflation expectations based on last year's inflation rate, what will be the inflation rate this year?

In an economic model where inflation expectations for the current period are based on the actual inflation rate of the previous period, what is the consequence of a positive bargaining gap that persists for several consecutive years?

In an economic model where inflation expectations are based on the previous period's inflation rate, the current inflation rate will be equal to the previous period's inflation rate if, and only if, the bargaining gap is zero.

Analyzing the Bargaining Gap

An economy's inflation rate is observed to be 3% in Year 1, 5% in Year 2, and 7% in Year 3. If it is assumed that people's expectation of inflation in any given year is equal to the actual inflation rate of the previous year, what can be concluded about the bargaining gap during this period?

Explaining the Wage-Price Spiral Mechanism

Suppose an economy experienced an inflation rate of 5% last year. The central bank's goal is to achieve an inflation rate of 3% this year. Assuming economic agents form their inflation expectations based on last year's actual inflation rate, what must the bargaining gap be this year for the central bank to meet its target?

An economy starts with zero inflation. A persistent positive bargaining gap then emerges. Assuming people's inflation expectations for any given period are based on the actual inflation rate of the previous period, arrange the following events in the correct chronological order to describe the resulting wage-price spiral.

A government official claims that to permanently lower inflation from 5% to a new, stable rate of 3%, it is sufficient to implement a policy that creates a temporary, one-period negative bargaining gap of -2%. After this single period, the bargaining gap will return to zero. Within a framework where inflation expectations are based on the previous period's inflation rate, is this claim correct?
