Phillips Curve Equation with Adaptive Expectations
The Phillips curve equation, which states that inflation is the sum of expected inflation and the bargaining gap (), can be specified for the case of adaptive expectations. Under this assumption, economic agents form their expectation of inflation based on the previous period's inflation rate, meaning . Substituting this into the general equation yields the formula: This equation demonstrates that current inflation depends on past inflation and the current bargaining gap, providing a mathematical basis for the wage-price spiral and accelerating inflation when a positive bargaining gap persists.

Analyzing Wage Negotiations and Inflation
An economy is operating with stable prices and an inflation expectation of 0%. A new government policy is introduced that significantly reduces the collective bargaining power of workers. Assuming wages are the primary determinant of prices and inflation expectations do not change, what is the most likely immediate effect?
In an economy where the actual inflation rate is determined by the sum of what people expect inflation to be and a 'bargaining gap' reflecting labor's negotiating strength, it is observed that for several years, actual inflation has been consistently higher than expected inflation. What does this persistent difference imply about the state of the labor market during this time?
Arrange the following events into the correct causal sequence that explains how the actual inflation rate is determined, based on the model where wages are the primary cost of production.
Calculating and Interpreting the Bargaining Gap
An economy's inflation is determined by the sum of what people expect inflation to be and the 'bargaining gap' that reflects workers' negotiating power. This relationship holds because it is assumed that firms set prices based solely on their labor costs. Consider a scenario where expected inflation is 3% and a strong labor market creates a positive bargaining gap of 2%. If a sudden, separate global event causes the cost of imported raw materials to rise for all firms, what will be the resulting inflation rate?
According to the principle that the inflation rate is determined by the sum of what people expect inflation to be and the 'bargaining gap', the actual observed inflation rate can never be lower than the expected inflation rate.
Critique of the Wage-Driven Inflation Model
In a simplified economy, it is assumed that the percentage increase in prices is determined solely by the percentage increase in wages. Workers expect prices to rise by 3% and, due to a strong labor market, successfully negotiate a 5% nominal wage increase. However, the actual measured price increase at the end of the year is only 4%. Which of the following provides the best explanation for why the price increase was lower than the wage increase?
Match each economic term with its correct definition in the context of a model where price changes are driven by wage changes.

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?
