The Role of Central Bank Credibility in Anchoring Inflation Expectations
Central banks closely monitor inflation expectations because they are crucial for price stability. A central bank can prevent these expectations from rising—a process known as anchoring—by establishing a track record of reliability in keeping inflation near its target. This credibility is fundamentally built on the central bank's demonstrated willingness to confront policy dilemmas, even if it means temporarily raising unemployment to prevent inflation from becoming entrenched. By successfully anchoring expectations, the central bank makes its own job of managing the economy significantly easier.

An economy experiences a sudden, sharp increase in the price of all imported raw materials, leading to higher production costs for most businesses. In response, the central bank announces it will prioritize maintaining the current level of employment and will avoid any immediate actions that might slow down the economy. Based on this policy choice, what is the most significant risk the central bank is accepting?

An economy, initially at a stable rate of inflation and employment, is hit by a severe drought that drastically reduces agricultural output and pushes up food prices.

Central Bank Policy in Response to an Inflationary Shock
Two countries, Country A and Country B, experience an identical, unexpected surge in global energy prices, causing a temporary spike in inflation. The central bank of Country A has a long-established, proven track record of keeping inflation at its target, whereas the central bank of Country B has a history of prioritizing short-term employment over its inflation target. Based on this information, which of the following outcomes is most likely?
Building Central Bank Credibility
