Abstract: We consider inflation and debt dynamics under a global interest rate rule when private agents forecast using adaptive learning. Given the zero lower bound on interest rates, active interest rate rules are known to imply the existence of a second, low-inflation steady state. Under learning the economy can slip below this low-inflation steady state and be driven to an even lower inflation floor supported by a switch to an aggressive money supply rule. Fiscal policy alone cannot push the economy out of this liquidity trap. Raising the inflation floor sufficiently can ensure a return to the target equilibrium. (Copyright: Elsevier)
