National accounts data are always revised. Not only recent data, but also figures dating many years back can be revised substantially. This means that there is a danger that an important part of the central bank's information set is flawed for a long period of time. In this paper we present a...

We consider the properties of two monetary policy rules ("strict inflation targeting", "constant money growth rule") in an intertemporal equilibrium model with flexible prices in which monetary policy is "active", while fiscal policy is "passive". Specifically, we assume that the fiscal agent...

This paper develops a small New Keynesian model with capital accumulation and government debt dynamics. The paper discusses the design of simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption,...

We analyse the interaction between private agents? uncertainty about inflation target and the central bank's data uncertainty. In our model, private agents update their perceived inflation target and the central bank estimates unobservable economic shocks as well as the perceived inflation...

In this paper we carry over a static version of a New Keynesian Macro Model to a monetary union. For a similar approach see Uhlig (2002). We will show in particular that a harmonious functioning of a monetary union critically depends on the correlation structure of shocks that hit the currency...

I analyze how the introduction of financial frictions can affect the trade-off between output stabilization and inflation stability and whether, in the presence of financial frictions, the optimal outcome can be realized or approached more closely if monetary policy is allowed to react to...

Liquidity plays an important role in explaining how banks determine their allocation of funds. This paper analyses whether this fact can explain the term structure of interest rates and yield spreads. The paper models banks' demand for liquidity in a manner similar to that used to study...

In this paper we carry over a static version of a New Keynesian Macro Model developed in previous papers (see Bofinger, Mayer, and Wollmershäuser 2002) to a monetary union. For a similar approach see (Uhlig 2002). We will show in particular that a harmonious functioning of a monetary union...

A dynamic general equilibrium two-country optimizing model is used to analyze the welfare effects of monetary policy in open economies. The distinguishing feature of the model is that households' preferences feature a "keeping up with the Joneses" effect. This effect implies that households'...

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...
