Nonlinear Monetary Policy Tradeoffs

Thu, 01 Jan 2026 00:00:00 +0000

This paper measures how the inflation-unemployment tradeoff associated with monetary policy varies with both the sign of the monetary intervention (easing versus tightening) and the state of the business cycle (booms versus recessions) for the US economy over 1973:M1 to 2019:M6. The motivation is that standard linear Phillips-curve estimates implicitly impose a constant tradeoff, yet a flat Phillips curve would simultaneously predict that (i) stimulating activity during a recession costs nothing in terms of inflation and (ii) reducing inflation costs very large amounts of unemployment — both empirically extreme predictions that have very different policy implications. The paper challenges both extremes.
