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 |
