A widely spread belief among economists is that monetary policy has relatively short-lived effects on real variables such as unemployment. Previous studies indicate that monetary policy affects the output gap only at business cycle frequencies, but the effects on unemployment may well be more...

This paper presents a synoptic interpretation of structural unemployment in Europe. The paper consists of three parts. Part 1 summarises some major stilysed facts of the record and the state of unemployment in Europe. In part 2, these facts are taken as the basis for a theoretical interpretation...

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...

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 show that low trend inflation strongly affects the dynamics of a standard Neo-Keynesian model where monetary policy is described by a standard Taylor rule. Moreover, trend inflation enlarges the indeterminacy region in the parameter space, substantially altering the so-called Taylor...

This paper shows that in inflation in industrialized countries is largely a global phenomenon. First, inflations of (22) OECD countries have a common factor that alone accounts for nearly 70% of their variance. This large variance share that is associated to Global Inflation is not only due to...

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

We ask why, in many circumstances and many environments, decision-makers choose to act on a time-regular basis (e.g. adjust every six weeks) or on a stateregular basis (e.g. set prices ending in a 9), even though such an approach appears suboptimal. The paper attributes regular behaviour to...

In this paper, we show that strategic complementarities'such as firm-specific factors or quasikinked demand?have crucial implications for the design of monetary policy and for the welfare costs of output and inflation variability. Recent research has mainly used log-linear approximations to...

Analyzing a large weekly retail transaction price dataset, we uncover a surprising regularity'small price increases occur more frequently than small price decreases for price changes of up to about 10 cents, while there is no such asymmetry for larger price changes. The asymmetry holds for the...
