This book studies the interactions between monetary and fiscal poUcies in the euro area. It carefully discusses the process of policy competition and the structure of policy cooperation. As to policy competition, the focus is on competition between the European central bank, the American central bank, the German government, and the French government. As to policy cooperation, the focus is on the same institutions. These are higher-dimensional issues. The pohcy targets are price stability and full employment. The policy makers follow co- turkey or gradualist strategies. The policy decisions are taken sequentially or simultaneously. Monetary and fiscal policies have spillover effects. Special features of this book are numerical simulations of policy competition and numerical solutions to policy cooperation. The present book is part of a larger research project on European Monetary Union, see the references at the back of the book. Some parts of this project were presented at the World Congress of the International Economic Association. Other parts were presented at the International Conference on Macroeconomic Analysis, at the International Institute of Public Finance, at the Macro Study Group of the German Economic Association, at the Annual Meeting of the Austrian Economic Association, at the Gottingen Workshop on International Economics, at the Halle Workshop on Monetary Economics, at the Research Seminar on Macroeconomics in Freiburg, and at the Passau Workshop on International Economics.

This book studies the sustainability and optimality of public debt under different scenarios: the closed economy, the small open economy, and a two-country setting. Sustainability refers to the existence and the stability of the long-run equilibrium. Optimality relates to the path of public debt that maximizes discounted utility. The analysis is conducted within the framework of the Solow model, the overlapping generations model and the infinite horizon model. The government can follow different strategies, it either fixes the deficit ratio or the tax rate. As a result, a fixed deficit ratio generally can be sustained. By contrast, a fixed tax rate generally cannot be sustained. Depending on the chosen fiscal strategy, there exists either an optimal deficit ratio or an optimal tax rate that maximizes the sum of consumption and government purchases per capita.

This book studies the strategic interactions between monetary and fiscal policies in the world economy. The world economy consists of two regions, say Europe and America. The policy makers are the central banks and the governments. The policy targets are low inflation, low unemployment, and low structural deficits. There are demand shocks, supply shocks, and mixed shocks. There are regional shocks and common shocks. This book develops a series of basic, intermediate, and more advanced models. Here the focus is on the Nash equilibrium. The key questions are: Given a shock, can policy interactions reduce the existing loss? And to what extent can they do so? Another topical issue is policy cooperation. To illustrate all of this there are a lot of numerical examples. The present book is part of a larger research project on European Monetary Union, see the references given at the back of the book.

A comprehensive study of the international coordination of economic policy in a monetary union. It carefully discusses the process of policy competition and the structure of policy cooperation. As to policy competition, the focus is on competition between the union central bank, the German government, and the French government. Similarly, as to policy cooperation, the focus is on cooperation between the union central bank, the German government, and the French government. The key questions are: Does the process of policy competition lead to full employment and price stability? Can these targets be achieved through policy cooperation? And is policy cooperation superior to policy competition? Another important issue is monetary competition / monetary cooperation between Europe and America.

This book studies the causes and cures of inflation in a monetary union. It carefully discusses the effects of money growth and output growth on inflation. The focus is on producer inflation, currency depreciation and consumer inflation. For instance, what determines the rate of consumer inflation in Europe, and what in America? Moreover, what determines the rate of consumer inflation in Germany, and what in France? Further topics are real depreciation, nominal and real interest rates, the growth of nominal wages, the growth of producer real wages, and the growth of consumer real wages. Here productivity growth and labour growth play significant roles. Another important issue is target inflation and required money growth. A special feature of this book is the numerical estimation of shock and policy multipliers.

This book explores the scope and limits of macroeconomic policy in a monetary union. The focus is on pure policies, policy mixes, and policy coordination. The leading protagonists are the union central bank, national governments, and national trade unions. Special emphasis is put on wage shocks and wage restraint. This book develops a series of basic, intennediate, and advanced models. A striking feature is the numerical estimation of policy multipliers. A lot of diagrams serve to illustrate the subject in hand. The monetary union is an open economy with high capital mobility. The exchange rate between the monetary union and the rest of the world is floating. The world interest rate can be exogenous or endogenous. The union countries may differ in money demand, consumption, imports, openness, or size. Previous versions of some parts were presented at the Annual Conference of the Gennan Economic Association and . at the Workshop on International Economics. I have benefited from comments by Christopher Bliss, Volker Clausen, Johannes Hackmann, Bernd Hayo, Jay H. Levin, Reinar Ludeke, Dirk Meyer, Jochen Michaelis, Franco Reither, Gerhard Rubel, WolfScMfer, Michael Schmid, Reinhard Selten, Hans-Werner Sinn, Sylvia Staudinger, Thomas Straubhaar, Bas van Aarle, and Artur Woll. In addition, Michael Brauninger and Michael Cyrus carefully discussed with me all parts of the manuscript. Last but not least, Doris Ehrich did the secretarial work as excellently as ever. I wish to thank all of them. Executive Summary 1) The monetary union as a whole. First consider fiscal policy.

This book studies the international coordination of monetary and fiscal policies in the world economy. It carefully discusses the process of policy competition and the structure of policy cooperation. As to policy competition, the focus is on monetary and fiscal competition between Europe and America. Similarly, as to policy cooperation, the focus is on monetary and fiscal cooperation between Europe and America. The spillover effects of monetary policy are negative while the spillover effects of fiscal policy are positive. The policy targets are price stability and full employment. The policy makers follow either cold-turkey or gradualist strategies. Policy expectations are adaptive or rational. The world economy consists of two, three or more regions. The present book is part of a larger research project on European Monetary Union, see the references at the back of the book. Some parts of this project were presented at the World Congress of the International Economic Association in Lisbon. Other parts were presented at the International Institute of Public Finance, at the Macro Study Group of the German Economic Association, at the Annual Meeting of the Austrian Economic Association, at the Gottingen Workshop on International Economics, at the Halle Workshop on Monetary Economics, at the Research Seminar on Macroeconomics in Freiburg, and at the Passau Workshop on International Economics.

This book explores the new economics of monetary union. It carefully discusses the effects of shocks and policies on output and prices. Shocks and policies are country-specific or common. They occur on the demand or supply side. Countries can differ in behavioural functions. Wages can be fixed, flexible, or slow. In addition, fixed wages and flexible wages can coexist. Take for instance fixed wages in Germany and flexible wages in France. Or take fixed wages in Europe and flexible wages in America. A special feature of this book is the numerical estimation of shock and policy multipliers. Further topics are inflation and disinflation. Take for instance inflation in Germany and price stability in France. Then what policy is needed for disinflation in the union? And what will be the dynamic effects on Germany and France?

This book studies the dynamics of monetary and fiscal interactions in the Euro Area. The policy makers are the European Central Bank and national governments. The primary target of the ECB is low inflation. And the primary target of a national government is low unemployment. However, there is a short-run trade-off between low inflation and low unemployment. Here the main focus is on sequential policy decisions. Another focus is on simultaneous and independent policy decisions. And a third focus is on policy cooperation. There are demand shocks, supply shocks, and mixed shocks. There are country-specific shocks and common shocks. The key question is: Given a shock, what are the dynamic characteristics of the resulting process?

This is what we ve all been waiting for a book that demystifies the European community 's monetary union. Unlike other books, this one provides readers with a practical yet sophisticated grasp of the macroeconomic principles necessary to understand a monetary union. The most important case in point is the Euro area, where policy targets are price stability and full employment. To illustrate all of this there are numerical simulations of monetary policy, fiscal policy, and wage policy.

This book studies interactions between monetary and wage policies in the Euro area, closely reviewing and discussing the process of policy competition and the structure of policy cooperation. On policy competition, the book focuses on competition between the European central bank, the American central bank, the German labour union, and the French labour union. As to policy cooperation, the focus is on the same institutions. Includes numerical simulations and solutions.

This book studies unemployment and inflation in economic crises, first considering the scenario of a demand shock in Europe. In that case, monetary and fiscal interaction would cause widespread oscillations in European unemployment and European inflation. And what is more, there would be equally far-reaching fluctuations in the European money supply and European government purchases. These monetary and fiscal interactions would have no effects on the American economy. Second, it examines the scenario of a supply shock in Europe, in which monetary and fiscal interactions would have no effects on European unemployment or European inflation; there would also be an explosion of European government purchases and an implosion of the European money supply. Monetary and fiscal interactions would produce uniform oscillations in American unemployment and American inflation. Lastly, we would also see an implosion of both the American money supply and American government purchases.

European monetary unification seems to be one of the most important events in international monetary affairs since the breakdown of Bretton Woods. It pos es a major challenge to central banks, governments, and labour unions. It opens up new fields of economic research that are both intriguing and fascinating. European Monetary Union amounts to a switch of regime. Surely the Mundell Fleming model of the open economy does no longer apply to Germany or France. The effects of shocks and policies on output and prices should have changed dramatically in size. Some of them should even work in the opposite direction now. The present book is part of a larger research project on monetary union, see Carlberg (1999, 2000, 2001, 2002, 2003). Some parts of this project were presented at the World Congress of the International Economic Association in Lisbon. Other parts were presented at the Macro Study Group of the German Economic Association, at the Annual Meeting of the Austrian Economic Association in Klagenfurt, at the Pass au Workshop on International Economics, at the Halle Workshop on Monetary Economics, and at the Research Seminar on Macroeconomics in Freiburg. Moreover, book reviews were published in the Economic Journal, Kyklos, the Journal of Economics, and the Journal of Economics and Statistics."

This book studies the coexistence of inflation and unemployment in a monetary union. The focus is on how to reduce the associated loss. The primary target of the European central bank is low inflation in Europe. The primary target of the German government is low unemployment in Germany. And the primary target of the French government is low unemployment in France. The European central bank has a quadratic loss function. The same applies to the German government and the French government. The key questions are: To what extent can the sequential process of monetary and fiscal decisions reduce the loss caused by inflation and unemployment? Is monetary and fiscal cooperation superior to the sequential process of monetary and fiscal decisions? The present book is part of a larger research project on European Monetary Union, see the references given at the back of the book.
