Policy rate ceiling and Taylor's Rule. Taylor's Rule is a formula that links a central bank's policy rate to inflation and economic growth. Developed by economist John Taylor in 1993, this rate assumes an equilibrium federal funds rate of 2% above the annual inflation rate. The Taylor Rule adjusts the equilibrium rate based on the deviation from the central bank's targets in inflation and real GDP growth. Exceeding inflation and growth targets raise the policy rate under the Taylor Rule, while reducing the deficits. The basic Taylor Rule formula does not take into account the ineffectiveness of negative interest rates or alternative monetary policy instruments such as asset purchases. The Taylor Rule formula makes inflation the single most important factor in setting rates, while the Fed has a dual mandate to promote stable prices and maximum employment.

Taylor-type rules have been evaluated in a large literature and it has been claimed that they characterize the near-optimal monetary policy in widely used macroeconomic models.
