Policymakers aim to anchor inflation expectations to a stable, low target to prevent the Phillips curve from shifting upward. The primary motivation for this goal is to avoid the need for a costly recession. While inducing a recession with higher unemployment may seem economically wasteful, it becomes the only available tool to combat inflation if expectations become unanchored. Successfully anchoring expectations makes such painful economic measures unnecessary.

Policy Goal of Anchoring Inflation Expectations

Based on the following scenarios, analyze why the central bank in Country B faces a significantly more difficult and potentially more economically costly task in bringing inflation back down to its target compared to the central bank in Country A.

Central Bank Credibility and Policy Challenges

A central bank governor states, "Our most important task is not just to control current inflation, but to firmly anchor the public's expectations of future inflation at our low target. Failing to do so would force us to make painful choices down the road." Analyze this statement. Explain why unanchored inflation expectations would necessitate "painful choices" and how successfully anchoring them helps avoid such a scenario.

The Rationale for Stable Inflation Expectations

If a central bank successfully keeps the public's expectations about future inflation low and stable, it means that the short-run trade-off between inflation and unemployment has been completely eliminated.

Imagine a scenario where a central bank has failed to keep inflation low and stable for several years. As a result, businesses and workers now anticipate that high inflation will continue indefinitely. What is the primary reason this change in public expectation makes it more difficult for policymakers to bring inflation back down to a low target?
