We derive the optimal fiscal transfer scheme for countries in a monetary union to off-set the welfare losses resulting from asymmetric shocks and nominal rigidities. Optimal transfers involve a trade-off between reducing national output gaps and the provision of consumption insurance across countries, where the weight of the former increases relative to the latter as consumption home bias rises. The welfare gains from optimal transfers increase in both home bias and export substitutability. When these parameters are calibrated to the data for specific euro area countries, the welfare gains from optimal transfers are as high as 3.6% of permanent consumption. ; The ADEMU Working Paper Series is being supported by the European Commission Horizon 2020 European Union funding for Research & Innovation, grant agreement No 649396.

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.

"This book introduces readers to the world of international financial markets and their integration on a global and regional scale. The author presents the theoretical and practical issues concerning the processes of financial market integration, with a particular focus on the monetary union. The empirical research results are based on econometric modelling, thus simplifying them for a non-specialist audience, who can instead concentrate on the author's conclusions, which comprise the results of these complicated research methods. The author outlines the role and functions of financial markets in the economy, in particular the relationship between financial intermediaries and financial markets and tackles the question of integration of new EU member countries' financial markets within the Eurozone. The integration of financial markets in an international context is inevitable and the author argues that we must learn how to benefit from it from in terms of economic growth. This book will be a valuable resource for students of economics and finance, particularly those studying financial management and international business and finance, as well as professionals in these fields. Further, this book will be of interest to anyone looking to discover more about the problems of globalization and the integration of financial markets in the modern economy"--

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
