I examine the impact of alternative monetary policy rules on a rational asset price bubble, through the lens of an overlapping generations model with nominal rigidities. A systematic increase in interest rates in response to a growing bubble is shown to enhance the fluctuations in the latter,...

The desirability of flexible exchange rates is a central tenet in international macroeconomics. We show that, with forward-looking staggered pricing, this result crucially depends on the monetary authority's ability to commit. Under full commitment, flexible exchange rates generally dominate a...

We employ Markov-switching regression methods to estimate fiscal policy feedback rules in the U.S. for the period 1960-2002. Our approach allows to capture policy regime changes endogenously. We reach three main conclusions. First, fiscal policy may be characterized, according to Leeper (1991)...

There has been a lot of interest recently in developing small scale rule-based empirical macro models for the analysis of monetary policy. These models, based on the conventional view that inflation stabilization should be a concern of monetary policy only, have typically neglected the role of...

Within a small open economy we derive a tractable framework for the analysis of the optimal monetary policy design problem as well as of simple feedback rules. The international relative price channel is emphasized as the one peculiar to the open economy dimension of monetary policy. Hence...
