Theory-Based Models
Theory-Based Models
A monetary-policy route for seeing how the policy rate moves when inflation overshoots or the economy runs above potential.
Variables
Nominal interest rate set by the central bank.
Observed inflation.
Central bank inflation objective.
Distance from potential output.
Assumptions
The Taylor rule is a benchmark reaction function, not a full optimal policy solution.
It summarizes behavior rather than deriving it from a welfare problem.
Parameters
Real neutral policy benchmark.
Observed inflation for the active point.
Target inflation objective.
How strongly the rule responds to inflation misses.
How strongly the rule responds to output gaps.
Current gap from potential output.
Shock presets
Raises the inflation response coefficient.
Pushes the active point to a positive output gap.
