The Impact of Anchored Expectations on Disinflation Costs
The degree to which inflation expectations are anchored has a significant effect on the economic costs associated with reducing inflation. If expectations are firmly anchored at the target, a central bank can bring inflation under control with a smaller negative impact on economic output, because price and wage-setting behaviors are already aligned with the low-inflation goal.

The Impact of Anchored Expectations on Disinflation Costs
Central Bank Credibility and Inflation Expectations
Consider two countries, both with a stated inflation target of 2%. The central bank in Country A has a long and consistent track record of meeting this target, earning significant public trust. In contrast, the central bank in Country B has frequently missed its target, and its policy announcements are often viewed with skepticism. If both countries experience an identical, temporary external shock that pushes current inflation to 5%, how would the public's long-term wage and price-setting behavior most likely differ between the two countries?
The Credibility Gap: Actions vs. Announcements
True or False: If a central bank has established high credibility and successfully anchored the public's inflation expectations at 2%, a sudden, temporary increase in oil prices that pushes current inflation to 5% will likely cause long-term wage negotiations to immediately incorporate an expectation of 5% future inflation.

Central Bank Policy Scenarios
Imagine two countries, Country A and Country B, both aiming for a 2% inflation rate. The central bank in Country A has a long, consistent history of meeting this target, earning high public trust. The central bank in Country B has a history of frequently missing its target, leading to public skepticism about its commitments. If both countries experience a sudden, identical surge in inflation to 8% and both central banks announce identical policies to bring inflation back down to 2%, which of the following outcomes is most likely?

Public Trust and the Economic Cost of Taming Inflation
If a country's businesses and workers widely expect inflation to remain high, a central bank can reduce the actual inflation rate with a smaller increase in unemployment than if expectations were low and stable.
