These notes try to clarify some discussions on the formulation of individual intertemporal behavior under adaptive learning in representative agent models. First, we discuss two suggested approaches and related issues in the context of a simple consumption-saving model. Second, we show that the...

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 attempts to assess the relative activism of these three central banks, with reference to the debate on interest rate smoothing. It investigates smoothing in terms of the pattern of interest rate changes, and estimates a series of Taylor-type policy rules for each bank, using quarterly...
