摘要
Central banks face uncertainty about the true location of the effective lower bound (ELB) on nominal interest rates. We model optimal discretionary monetary policy during a liquidity trap when the central bank designs policy that is robust with respect to the location of the ELB. If the central bank fears the worst-case location of the ELB, monetary conditions will be more expansionary in the period before the liquidity trap.
