Abstract

This paper analyzes optimal monetary policy under zero lower bound in the presence of cost channel. Cost channel introduces trade-o¤ between output and inflation when economy is out of ZLB. As a result, exit time both under discretion and commitment is endogenous in the presence of cost channel. Paper also finds that commitment outperforms discretion by promising future boom and inflation and a T-only policy closely replicates commitment both under presence and absence of cost channel.
