This paper takes a first step in analysing how a monetary union performs in the presence of labour market asymmetries. Differences in wage flexibility, market power and country sizes are allowed for in a setting with both country-specific and aggregate shocks. The implications of asymmetries for...

The optimal policy response to a low-probability extreme event is examined. A simple policy problem is solved for a sequence of different loss functions: quadratic, combined quadratic/absolute-deviation, absolute-deviation, combined quadratic/constant, and perfectionist. The Paper shows that,...

The present paper extends the literature on central bank transparency that relies on information heterogeneity among private agents in four directions. First, it adds the interest rate to the list of signals that the central bank can reveal. Second, it allows for more than one economic...

This survey outlines the general lessons of the recent literature on imperfectly competitive macroeconomies for the theory of monetary and fiscal policy. A general framework is presented which encompasses most of the existing literature. Although money is of itself neutral in these models, the...

We consider standard cash-in-advance monetary models and show that there are interest rate or money supply rules such that equilibria are unique. The existence of these single instrument rules depends on whether the economy has an infinite horizon or an arbitrarily large but finite horizon.

Within a simple New Keynesian model emphasizing forward-looking behaviour of private agents, I evaluate optimal nominal income growth targeting versus optimal inflation targeting. When the economy under consideration is mainly subject to shocks that do not involve monetary policy trade-offs for...

?This Paper considers monetary policy when the weight policy makers put on output loss relative to inflation is their private information. I show that in the first period of a two-period term, all policy makers but the least inflation averse inflate less – but respond more to shocks – than...

This paper focuses on the interaction of monetary policy and wage formation in economies with strong labour unions. Government and unions are viewed as endogenous utility maximizers, and the macroeconomic consequences of their interaction are explored with the aid of some elements of game...

We present an empirical analysis of German money demand, money supply and monetary policy after German monetary union in 1990. Empirical models for velocity and forecast models for the money multiplier are estimated. Stability analysis reveals that structural stability of the demand for broad...

This paper addresses a number of questions which are essential to a proper understanding of the causes and effects of the inflationary process and to an assessment of the contribution of monetary policy to the achievement of long-term price stability. These questions are: (1) what are the...
