Africa is working toward the goal of creating a common currency that would serve as a symbol of African unity. The advantages of a common currency include lower transaction costs, increased stability, and greater insulation of central banks from pressures to provide monetary financing. Disadvantages relate to asymmetries among countries, especially in their terms of trade and in the degree of fiscal discipline. More disciplined countries will not want to form a union with countries whose excessive spending puts upward pressure on the central bank's monetary expansion. In T he Monetary Geography of Africa, Paul Masson and Catherine Pattillo review the history of monetary arrangements on the continent and analyze the current situation and prospects for further integration. They apply lessons from both experience and theory that lead to a number of conclusions. To begin with, West Africa faces a major problem because Nigeria has both asymmetric terms of trade—it is a large oil exporter while its potential partners are oil importers—and most important, large fiscal imbalances. Secondly, a monetary union among all eastern or southern African countries seems infeasible at this stage, since a number of countries suffer from the effects of civil conflicts and drought and are far from achieving the macroeconomic stability of South Africa. Lastly, the plan by Kenya, Tanzania, and Uganda to create a common currency seems to be generally compatible with other initiatives that could contribute to greater regional solidarity. However, economic gains would likely favor Kenya, which, unlike the other two countries, has substantial exports to its neighbors, and this may constrain the political will needed to proceed. A more promising strategy for monetary integration would be to build on existing monetary unions—the CFA franc zone in western and central Africa and the Common Monetary Area in southern Africa. Masson and Pattillo argue that the goal of a creating a s

" Assessing the potential benefits and risks of a currency union Leaders of the fifteen-member Economic Community of West African States (ECOWAS) have set a goal of achieving a monetary and currency union by late 2020. Although some progress has been made toward achieving this ambitious goal, major challenges remain if the region is to realize the necessary macroeconomic convergence and establish the required institutional framework in a relatively short period of time. The proposed union offers many potential benefits, especially for countries with historically high inflation rates and weak central banks. But, as implementation of the euro over the past two decades has shown, folding multiple currencies, representing disparate economies, into a common union comes with significant costs, along with operational challenges and transitional risks. All these potential negatives must be considered carefully by ECOWAS leaders seeking tomeet a self-imposed deadline. This book, by two leading experts on economics and Africa, makes a significant analytical contribution to the debates now under way about how ECOWAS could achieve and manage its currency union, andthe ramifications for the African continent.

The past twenty years have seen two waves of research on currency unions, prompted by the early experience of the European Economic and Monetary Union and by the existential crisis experienced by the euro area as a part of the global financial crisis. Alongside an original introduction, this important collection assembles key papers exploring a range of themes in these two waves of research, including subtopics such as reassessment of optimal currency area theory, new views on the policy choices, and the past and present experience of various currency unions. With a concluding section that addresses the question of complementary institutions going beyond an inflation-focused central bank, this two-volume collection provides an ample and comprehensive overview of currency unions.

The European Community is negotiating a new treaty to establish the constitutional foundations of an economic and monetary union in the course of the 1990s. This study provides the only comprehensive guide to the economic implications of economic and monetary union. The work of an economist inside the Commission of the European Community, it reflects the considerations influencing the design of the union. The study creates a unique bridge between the insights of modern economic analysis and the work of the policy makers preparing for economic and monetary union.

The book covers problems relating to international macroeconomics and international finance. The first part develops new approaches to exchange rate modeling. The second part is a collection of papers on the theory and empirical analysis of monetary unions. The third part contains criticism of the mainstream macroeconomic models and proposes alternative modeling approaches.

Currency Unions reviews the traditional case for flexible exchange rates and "countercyclical"—that is, expansionary during recessions and contractionary in booms—monetary policy, and shows how flexible exchange rate regimes can better insulate the economy from such real disturbances as terms-of-trade shocks. The book also looks at the pitfalls of flexible exchange rates—and why fixed rates, particularly full dollarization—might be a more sensible choice for some emerging-market countries. The contributors also detail the factors that determine the optimal sizes of currency unions, explain how currency union greatly expands the volume of international trade among its members, and examine the recent implementation of dollarization in Ecuador.
