  1. Chapter 16 What Should Central Banks Do? Monetary Policy Goals, Strategy, and Tactics

  2. The Price Stability Goal • Low and stable inflation • Inflation • Creates uncertainty and difficulty in planning for future • Lowers economic growth • Strains social fabric • Nominal anchor • Time-inconsistency problem

  3. Other Goals of Monetary Policy • High employment • Economic growth • Stability of financial markets • Interest-rate stability • Foreign exchange market stability

  4. Should Price Stability be the Primary Goal? • In the long run there is no conflict between the goals • In the short run it can conflict with the goals of high employment and interest-rate stability • Hierarchical mandate • Dual mandate

  5. Monetary Targeting • Flexible, transparent, accountable • Advantages • Almost immediate signals help fix inflation expectations and produce less inflation • Almost immediate accountability • Disadvantages • Is there a strong and reliable relationship between the goal variable and the targeted monetary aggregate?

  6. Inflation Targeting • Public announcement of medium-term numerical target for inflation • Institutional commitment to price stability the primary, long-run goal of monetary policy • Information-inclusive approach in which many variables are used in making decisions • Advantages • Does not rely on one variable to achieve target • Easily understood • Reduces potential of time-inconsistency trap • Stresses transparency and accountability • Disadvantages • Delayed signaling • Too much rigidity • Potential for increased output fluctuations • Low economic growth during disinflation

  7. Implicit Nominal Anchor/Greenspan Standard • Forward looking and preemptive • Advantages • Uses many sources of information • Avoids time-inconsistency problem • Demonstrated success • Disadvantages • Lack of transparency and accountability • Strong dependence on the preferences, skills, and trustworthiness of individuals in charge • Inconsistent with democratic principles

  8. Tactics: Choosing the Policy Instrument • Tools • Open market operation • Reserve requirements • Discount rate • Policy instrument (operating instrument) • Reserve aggregates • Interest rates • May be linked to an intermediate target • Can’t have interest-rate and aggregate targets • Choose one or the other Criteria for Choosing Policy Instrument • Observability and Measurability • Controllability • Predictable effect on Goals

  9. Taylor Rule, NAIRU, and Phillips Curve • React to inflation gap and to output gap • Stabilizing real output is an important concern • Output gap is an indicator of future inflation as shown by Phillips curve • NAIRU • Rate of unemployment at which there is no tendency for inflation to change
