In sticky price models with endogenous investment, virtually all monetary policy rules that set a nominal interest rate in response solely to future inʿation induce real indeterminacy of equilibrium. Applying the Samuelson-Farebrother conditions, we obtain a necessary and suffcient condition...

This paper shows that announced credible disinflations under inflation targeting lead to a boom in a standard New Keynesian model (i.e. a disinflationary boom). This finding is robust with respect to various parameterizations and disinflationary experiments. Thus, it differs from previous...

In a model with forward-looking expectations, the paper examines communication of central bank forecasts when the inflation target is subject to unobserved changes. It characterizes the effect of disclosure of forecasts on inflation and output stabilization and the choice of an active versus...

We study the design of optimal monetary policy (Ramsey policies) in a model with sticky prices and unionized labour markets. Collective wage bargaining and unions monopoly power tend to dampen wage fluctuations and to amplify employment fluctuations relatively to a DNK model with walrasian...

This paper studies the relative performance of alternative monetary policy rules in the presence of oil price shocks in a small open economy optimizing model. Our analysis shows that it is important to distinguish between alternative price indices (CPI, core CPI, and GDP deflator) when modeling...

We examine 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 locally but not globally stable. Large pessimistic shocks to expectations can lead...

This article investigates the empirical relationship between monetary policy in the United States (US) and international equity, bond and real estate security markets for the sample period 01/1994 to 12/2007. The empirical results suggest that equity markets close to the US have a statistically...

This paper studies the effects of ECB communications about unconventional monetary policy operations on the perceived sovereign risk of Italy over the last five years. More than fifty events concerning non-standard operations are identified and classified with respect to the specific ECB...

We provide a systematic analysis of fiscal consolidation in a medium-scale dynamic general equilibrium model. Our results show that the choice of the consolidation instrument is very important, not only with respect to the short- and long-run output effects of the different consolidation...

This paper uses a dynamic general equilibrium optimizing two-country model to analyze how the formation of exchange rate expectations shapes the effects of monetary policy shocks in open economies. The model implies that the short-run output effects of permanent monetary policy shocks diminish...
