We study a many country endogenous growth model in which decisions about innovation and new investment are influenced by growth expectations. Adaptive learning dynamics determine country-specific short run transition paths. Countries differ in basic structural parameters and may impose tariffs...

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...

This topical book addresses the need for emerging economies in Central, Eastern and South-Eastern Europe to find a new, sustainable growth model that fosters continued convergence with the EU without leading to the build-up of new vulnerabilities.

Against the backdrop of the financial crisis that unfolded in 2008, this book deals with policy challenges going forward, focusing in particular on the ongoing catching-up process in Central, Eastern and South-Eastern European countries.

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...

The paper provides an overview of the sovereign debt crisis. I first consider the build-up of the crisis. I then discuss policy choices when a financial crisis erupts and assess the adjustment processes in the crisis countries, including alternatives to policies of austerity. Finally I take up...

The design of interest rate rules for conducting monetary policy have recently been examined for two key concerns. The first issue is determinacy of equilibria. Indeterminacy (multiplicity of stationary rational expectations equilibria) is a concern in models of monopolistic competition and...

We examine a recursive algorithm for learning steady states and cycles in stochastic nonlinear models. Necessary and sufficient conditions for local convergence are shown to be equivalent to easily computable expectational-stability conditions. These conditions are affected by the distribution...
