Monetary policy and learning in an open economy
Martin Ellison ()
, Lucio Sarno and Jouko Vilmunen ()
Abstract: In this paper, we examine the incentives for central bank
activism and caution in a two-country open-economy model with uncertainty
and learning. We find that the presence of a strategic interaction between
the home and foreign central banks creates an additional motivation for
caution in monetary policy. An activist policy designed to help the
learning of the home central bank is suboptimal since it generates a strong
reaction from the foreign central bank. As joint learning by the home and
foreign central banks is shown to be detrimental to welfare, the optimal
policy is cautious.
