We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. The intended steady state is locally but not globally stable. Unstable deflationary paths emerge after large pessimistic shocks to expectations. For...

This paper reports on the findings of Evans, Guse, and Honkapohja (2007) concerning the global economic dynamics under learning in a New Keynesian model in which the interest rate rule is subject to the zero lower bound. Under normal monetary and fiscal policy, the intended steady state is...
