Taylor Rule (1993)
β€”
Balanced Approach Rule
β€”
Divergence (Balanced βˆ’ Taylor)
β€”
When U > U*, the Balanced Approach prescribes a lower rate than Taylor. Divergence = 0 when unemployment is exactly at NAIRU.
Current Adjusted Taylor (1993)
4.34%
Current First-Difference Rule
4.14%
Both are path-dependent (accumulated ELB shortfall / lagged actual FFR), so they're shown as latest computed values rather than live-editable β€” see historical chart above.

Taylor Rule (1993): R = r* + Ο€ + 0.5Β·(Ο€ βˆ’ Ο€*) βˆ’ 1.0Β·(U βˆ’ U*)

Adjusted Taylor (1993): R = max(R_T93 βˆ’ Z, ELB), where Z is the cumulative sum of past Taylor-rule shortfalls below the ELB (Reifschneider-Williams "lower-for-longer" makeup).

Balanced Approach Rule: R = r* + Ο€ + 0.5Β·(Ο€ βˆ’ Ο€*) βˆ’ 2.0Β·(U βˆ’ U*)

First-Difference Rule: R = FFR_(tβˆ’1) + 0.5Β·(Ο€ βˆ’ Ο€*) βˆ’ (U_t βˆ’ U_(tβˆ’4))

The first three rules are written using the unemployment gap (via Okun's Law), where a 1% rise in unemployment β‰ˆ 2% drop in output. The Balanced Approach doubles the unemployment coefficient from βˆ’1.0 to βˆ’2.0, prescribing 200 bps of cuts per 1% of excess unemployment vs. 100 bps under Taylor. The Adjusted Taylor rule accounts for periods when the Taylor rule prescribes a rate below the effective lower bound (ELB) by holding the prescribed rate lower for longer once liftoff occurs, to make up for the shortfall in accommodation. The First-Difference rule instead anchors off the prior quarter's actual fed funds rate and reacts to the year-over-year change in unemployment, making it inertial and less sensitive to real-time estimates of r* or U*.
