Understanding the Taylor Rule

The Taylor rule is a monetary policy guideline that prescribes how central banks should set interest rates in response to changes in inflation and economic output. Named after economist John Taylor, it provides a systematic approach to monetary policy decision-making.

Taylor Rule Formula

Original Taylor Rule

  • i = r* + p + 0.5(p - p*) + 0.5(y - y*)
  • i = Nominal interest rate
  • r* = Equilibrium real interest rate
  • p = Actual inflation rate
  • p* = Target inflation rate
  • y - y* = Output gap

Simplified Version

  • i = r* + p + a(p - p*) + ß(y - y*)
  • a = Inflation response coefficient
  • ß = Output response coefficient
  • Typically a = 1.5, ß = 0.5
  • More flexible parameters

Key Components

Elements of the Taylor Rule

Equilibrium Real Rate

  • Long-run real interest rate
  • Neutral policy rate
  • Typically 2-3% in developed economies
  • Adjusts for potential growth

Inflation Gap

  • Difference between actual and target inflation
  • Primary focus of monetary policy
  • Strong response to inflation deviations
  • Prevents inflation expectations from becoming unanchored

Output Gap

  • Difference between actual and potential GDP
  • Measures economic slack
  • Secondary response to economic conditions
  • Helps stabilize employment

Taylor Rule Coefficients

Coefficient Typical Value Purpose Policy Implication
Inflation Response (a) 1.5 Control inflation Strong anti-inflation stance
Output Response (ß) 0.5 Stabilize output Moderate employment focus
Equilibrium Rate (r*) 2.0% Neutral policy Long-run policy anchor
