Between 1995 and 2005, the German economy has experienced a phase of weak economic growth. We analyze whether this weak growth performance can be attributed to the stance of monetary conditions during that period. We show that the real effective exchange rate did have almost no dampening effects...

In the standard New Keynesian sticky price model the central bank faces no contradiction between the stabilization of inflation and the stabilization of the welfare relevant output gap after a productivity shock hits the economy. When the standard model is enhanced by real wage rigidities or...

We analyze optimal monetary policy when a central bank has to learn about an unknown coefficient that determines the effect of surprise inflation on aggregate demand. We derive the optimal policy under active learning and compare it to two limiting cases---certainty equivalence policy and...

This paper has two aims. First, it provides simple theoretical models that highlight two channels whereby monetary shocks have permanent real effects and the interactions between these channels. Second, it presents an empirical dynamic model, covering a panel of EU countries, and derives the...

This paper takes a new look at the long-run dynamics of inflation and unemployment in response to permanent changes in the growth rate of the money supply. We examine the Phillips curve from the perspective of what we call "frictional growth", i.e. the interaction between money growth and...

Using a macroeconomic model with asset prices, we analyze how optimal monetary policy, and macroeconomic dynamics and performance are affected by the central bank’s desire to be robust against model misspecifications. Considering the worst-case model, we show that an increase in the central...

Monetary shocks largely affect economic activity in Western Australia. In smaller proportion, those shocks generate contractions in New South Wales, Victoria and South Australia, while economic activity in Queensland is significantly less affected. Finally, we develop a new approach to uncover...

In case of speculative attacks, the central banks' decisions to intervene or not to intervene seem to play an important role for the economic costs of currency crises. The central bank can either abstain from intervening or start an intervention, which in turn can be successful or unsuccessful....

Though the hypothesis that exchange rate regimes fully predetermine monetary policy in the face of external shocks hardly finds any advocates in the field of theory, it has crept into empirical research. This study adopts a careful and rigorous empirical approach that looks at monetary policy...
