What are the primary targets of most central banks in macro stabilization, and why is the choice important for the policy rule?

• A. Price stability (inflation) and maximum sustainable employment (output); credibility and the chosen rule depend on the target, influencing response to shocks.
• B. Currency stability and budget balance
• C. Stock market performance and trade balance
• D. Public debt reduction and tax policy autonomy

Answer: (A)

Central banks stabilize the economy by aiming for price stability (steady, predictable inflation) and maximum sustainable employment (the level of output and jobs the economy can sustain without generating accelerating inflation). This pairing shapes the policy rule because the central bank’s response to deviations from its targets depends on what it is trying to achieve. If inflation is above target, the rule typically pushes policy rates up to bring inflation back down; if output is below potential, the rule may ease policy to support demand. When both inflation and employment are targets, the central bank must balance keeping prices stable with supporting the real economy, which changes how aggressively it responds to different shocks and how it weighs inflation against output in the rule. Credibility matters: a well-anchored inflation target helps expectations remain stable, making policy more effective and allowing smaller adjustments to achieve stabilization. The other potential goals—currency stability, budget balance, stock market performance, or debt reduction—do not represent the typical dual mandate and would lead to different rules and trade-offs.
