Expected inflation is the rate at which wage-setters and price-setters believe inflation will be in the next period. This belief is a crucial determinant in their wage and price-setting behavior.

Expected Inflation

Milton Friedman argued that when unemployment is kept low, inflation continuously increases because of the role of expected inflation. As wage and price setters begin to anticipate rising prices, they incorporate these expectations into their wage demands and pricing decisions, which in turn fuels further inflation, making the simple Phillips curve relationship misleading.

The Role of Expected Inflation in Accelerating Inflation

The formation of inflation expectations is influenced by two key elements: how individuals and firms make decisions about the future and how they process and understand signals from current prices.

Factors Shaping Inflation Expectations

Based on the scenario provided, what kind of nominal wage increase is the union most likely to demand in its negotiations, and why is their belief about future price levels a critical factor?

Wage Contract Negotiation

Imagine two identical economies, A and B. Both currently have an inflation rate of 2% and a similar level of economic activity. However, in Economy A, businesses and workers widely anticipate that inflation will rise to 5% next year, while in Economy B, they expect inflation to remain stable at 2%. Analyze how this difference in expectations is likely to affect the actual inflation outcomes in each economy over the next year. In your answer, explain the specific mechanisms through which these expectations influence economic behavior.

The Self-Fulfilling Nature of Inflation Expectations

Imagine an economy where for several years, the annual rate of price increase has been stable at 2%, and both businesses and workers have come to expect this rate to continue. Now, suppose the central bank makes a credible announcement that it will pursue policies leading to a 5% annual rate of price increase. Explain how this change in expectations would likely affect the wage demands of workers and the pricing decisions of firms in the upcoming year, even before the actual rate of price increase changes.

Impact of Shifting Inflation Expectations

A national labor union is negotiating a new three-year wage contract. The current annual rate of price increase is 2%. The union is demanding an average annual wage increase of 4% for the duration of the contract. Which of the following statements provides the most accurate economic explanation for the union's demand?
