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 both the overall performance of the monetary union and the country-specific situation are analysed. It is shown that asymmetries are not only critical for country-specific performance but also for the overall performance of the monetary union. A striking finding is that aggregate output volatility is not strictly increasing in nominal rigidities but hump-shaped. Moreover, a disproportionate share of the consequences of wage inflexibility may fall on small countries. In the case of country-specific shocks, a country unambiguously benefits in terms of macroeconomic stability by becoming more flexible, while this is not necessarily the case for aggregate shocks. There may thus be a tension between the degree of flexibility considered optimal at the country level and at the aggregate level within the monetary union.

The future European Central Bank needs monetary policy instruments which have yet to be agreed. At present, the range of instruments is very heterogeneous in the potential member states. This book offers a systematic analysis of the issue, considering general theoretical arguments as well as the concrete institutional situation in European countries. Taking the Bundesbank's instruments as the starting point, their rationale is discussed against the background of experience elsewhere. The theoretical and empirical treatment leads to several competing concepts. Taking the three goals of monetary efficiency, fair competition and decentralization establishes a strong case for the use of "standing facilities" and to a lesser extend "reserve requirements", albeit modified and brought up-to-date

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 both the overall performance of the monetary union and the country-specific situation are analysed. It is shown that asymmetries can have important effects, and that there are substantial spill-over effects. Among other things, it is found that aggregate output volatility is not strictly increasing in nominal rigidity but hump-shaped. A disproportionate share of the consequences of wage inflexibility may fall on small countries. In the case of country-specific shocks a country unambiguously benefits in terms of macroeconomic stability by becoming more flexible, but in general an inflexible country does not necessarily achieve more output stability by becoming more flexible. As this may be desirable for the monetary union as a whole, there is a risk of a ?reform deficit? in an asymmetric monetary union.

This paper investigates the dynamic effects of monetary and fiscal policy in a monetary union, which is characterized by asymmetric interest rate transmission. This asymmetry gives rise to intertemporal reversals in the relative effectiveness of policy on member country outputs. The direction and the number of these reversals depend on whether policies are unanticipated or anticipated. We also study the coordination between monetary and fiscal policy in a monetary union. Monetary policy may completely stabilize European output after unanticipated fiscal policy shocks. With anticipated fiscal policy shocks, complete stabilization throughout the overall adjustment process requires monetary policy to be time-inconsistent.

Using a DSGE model calibrated to the euro area, we analyze the international effects of afiscal devaluation (FD) implemented as a revenue-neutral shift from employer's socialcontributions to the Value Added Tax. We find that a FD in 'Southern European countries'has a strong positive effect on output, but mild effects on the trade balance and the realexchange rate. Since the benefits of a FD are small relative to the divergence incompetitiveness, it is best addressed through structural reforms
