Using New Keynesian models, we compare Friedman’s k-percent money supply rule to optimal interest rate setting, with respect to determinacy, stability under learning and optimality. We first review the recent literature. Open-loop interest rate rules are subject to indeterminacy and...

The study deals with the international transmission of economic shocks, their consequences for exchange rates and the reconciliation of exchange rate management with monetary policy. The theoretical part of the study consists of a mainstream model of two large, interdependent economies with...

This study is concerned with the determinants of monetary policy in the ERM countries. We derive a monetary policy rule, an interest rate rule, from a minimization problem faced by the central bank. The loss function trades off costs of interest rate instability against benefits from successful...

We examine global dynamics under infinite-horizon learning in New Keynesian models where the interest-rate rule is subject to the zero lower bound. As in Evans, Guse and Honkapohja (2008), the intended steady state is locally but not globally stable. Unstable deflationary paths emerge after...

We examine global dynamics under infinite-horizon learning in New Keynesian models where monetary policy practices either pricelevel or nominal GDP targeting and compare these regimes to inflation targeting. These interest-rate rules are subject to the zero lower bound. Robustness of the three...
