ìNew" Views on the Optimum Currency Area Theory: What is EMU Telling US?

This paper traces the advancements of the optimum currency area theory through its successive phases: the "pioneering phase," the "cost-benefit phase," the "reassessment phase," and the "empirical phase" in which we focus mostly on Europe because there is now a wealth of data, research and other information on European integration. The thrust of the pioneering contributions is still relevant and that the analysis of the benefits and costs from monetary integration has greatly evolved. There are more benefits and some of the perceived costs are smaller than previously thought. We also need to distinguish between an "OCA question" and an "EMU question."

Endogeneities of Optimum Currency Areas: What brings Countries Sharing a Single Currency Closer together?

This paper brings together several strands of the literature on the endogenous effects of monetary integration: i.e., whether sharing a single currency may set in motion forces bringing countries closer together. The start of the European Economic and Monetary Union (EMU) has spurred a new interest in this debate. There are four areas that we analyse in this context: the endogeneity of economic integration, in which we look primarily at evidence on prices and trade; the endogeneity of financial integration or equivalently insurance schemes that can be provided by capital markets; the endogeneity of symmetry of shocks and (similarly) at synchronisation of outputs; and the endogeneity of product and labour market flexibility. The paper presents a conceptual framework within which to illustrate such endogeneities. We present diverse arguments and, where possible, explore the incipient empirical literature focussing on the euro area. On the whole, concerning EMU, our preliminary conclusion is one of moderate optimism. The different endogeneities that exist in the dynamics towards optimum currency areas are at work. How strong these endogeneities are and how quickly they do their work remains to be seen.Optimum Currency Area, Economic and Monetary Integration and EMU

What effects is EMU having on the euro area and its member countries? An overview

This paper addresses the effects of the European Economic and Monetary Union (EMU) since the introduction of the euro -- on economic and financial structures, institutions and performance. What type of changes is the euro fostering? What forces is it setting in motion that were not there before? Six years after the launch of the euro, was an appropriate time to start taking stock of these effects. For this purpose, in June 2005, the ECB held a workshop on “What effects is EMU having on the euro area and its member countries?” The workshop was organised in five areas: 1. trade integration, 2. business cycles synchronisation, economic specialisation and risk sharing, 3. financial integration, 4. structural reforms in product and labour markets, and 5. inflation persistence. This paper sets the workshop in the context of the current debate on the effects of EMU and brings together several of the issues raised by the leading presentations: i.e., this paper serves as an overview. Overall, the effects of the euro observed are beneficial. However, progress has been uneven in the above areas. Many potential concerns preceding the launch of the euro have been dispelled. Moreover, it will take more time for the full effects of the euro to unravel. JEL Classification: E42, F13, F33, F42Economic and Monetary Integration and EMU, Optimum Currency Area

Endogeneities of optimum currency areas: what brings countries sharing a single currency closer together?

This paper brings together several strands of the literature on the endogenous effects of monetary integration: i.e., whether sharing a single currency may set in motion forces bringing countries closer together. The start of EMU has spurred a new interest in this debate. Four areas are analysed: the endogeneity of economic integration, in which we look primarily at evidence on prices and trade; the endogeneity of financial integration or equivalently of insurance schemes based on capital markets; the endogeneity of symmetry of shocks; and the endogeneity of product and labour market flexibility. We present diverse arguments and, where possible, explore the incipient empirical literature focussing on the euro area. Our preliminary conclusion is one of moderate optimism. The different endogeneities that exist in the dynamics towards optimum currency areas are at work. How strong these endogeneities are and how quickly they will do their work remains to be seen.

Convergence of fiscal policies in the euro area

This paper aims at determining whether economic, financial and monetary integration on the one hand, and institutional factors on the other, may have led to gradual convergence in key fiscal variables across the euro area over the recent period, bringing fiscal positions closer together. The Maastricht convergence criteria have facilitated this process but we investigate here whether the structural factors bringing fiscal positions closer together have been a feature of European integration starting already in the 1970s. The alternative scenario is that the euro zone is still characterised by largely idiosyncratic national fiscal policies. Over the 1970-1998 period we run contemporaneous cross-correlation, dispersion and cointegration tests using annual data for government net lending, and total current revenue and expenditure to uncover common trends, as measures of fiscal convergence. We also investigate whether the short term fiscal position in a given country shares both a common euro area component and national features (i.e., idiosyncratic national cycles) using a dynamic factor analysis on quarterly data for the four largest euro area countries since 1985. We find convincing evidence that for euro area countries cross-correlation has increased steadily over the sample period and that fiscal dispersion has been declining at a sustained pace among all countries in the sample. There is evidence of cointegration across the euro area for several countries on the basis of total current revenue, and also for total current expenditure. However, when the series are corrected for the business cycle, cointegration is only accepted for net lending. There is clearly common fiscal cycles for net lending across the euro area that do not only express common business cycles. However, while countries have followed more similar policies in the 1990s in particular during the run-up to EMU, the timing of fiscal adjustment differed across countries. In addition, idiosyncratic components still contribute to a significant share of the variability of individual countries. JEL Classification: H60, E61, C22

"New" views on the optimum currency area theory: what is EMU telling us?

This paper surveys the optimum currency area (OCA) literature. It is organised into four phases: the 'pioneering phase' which put forward the OCA theory and its properties, the 'reconciliation phase' when its diverse facets were combined, the 'reassessment phase' that led to the 'new OCA theory' and the 'empirical phase' during which the theory was subject to due empirical scrutiny. We make systematic reference to the European economic and monetary union (EMU) to which the OCA theory has been most frequently applied. All pioneering contributions are still relevant. Several early weaknesses have now been amended. Meanwhile, the balance of judgements has shifted in favour of currency unions. They are now deemed to generate fewer costs in terms of the loss of autonomy of domestic macroeconomic policies, and there is greater emphasis on the benefits. Looking ahead we are confronted with two distinct paradigms -- specialisation versus endogeneity of OCA.

Economic and monetary integration of the new Member States - helping to chart the route

This paper examines diverse aspects of the monetary integration of the ten new Member States (NMS) which joined the EU on 1 May 2004 into the euro area. Most NMS have undergone a rapid and deep transformation in all areas with considerable progress in their processes of reform and convergence, and more is underway. While trade integration with the other 15 EU Member States (EU15) has progressed quickly, convergence in output specialisation to EU standards has been slow, especially if measured in real terms. This may influence negatively the pace of real convergence. Most NMS lag significantly behind in building up and deepening their financial systems. There is also evidence that exchange rate flexibility may still be serving as a useful shock absorber for some NMS, and so far the evidence indicates that real exchange rates have moved, broadly speaking, in line with long term fundamental equilibria. On the positive side, many NMS are quite advanced relative to the euro area in the process of labour market and institutional reform (their labour market structures are more flexible than those of the euro area countries). There is also some evidence that a few NMS have a significant degree of business-cycle synchronisation with the euro area: hence, they may become less likely to be affected by different economic shocks. This, however, is not true for all NMS. The monetary policy institutions of the NMS have also converged to some degree - goals and institutional settings of central banks are now much more similar than before. A case-by-case approach to adopting the euro, based on country-specific conditions, seems natural due to the differences between the countries.Optimum Currency Area, Economic and Monetary Integration, EMU.

The Eurosystem, the US Federal Reserve and the Bank of Japan: similarities and differences

The paper provides a systematic comparison of the Eurosystem, the US Federal Reserve and the Bank of Japan. These monetary authorities exhibit somewhat different status and tasks, which reflect different historical conditions and national characteristics. However, widespread changes in central banking practices in the direction of greater independence and increased transparency, as well as changes in the economic and financial environment over the past 15-20 years, have contributed to reduce the differences among these three world’s principal monetary authorities. A comparison based on simple “over-the-counter” policy reaction functions shows no striking differences in terms of monetary policy implementation.

The working of the eurosystem - monetary policy preparations and decision-making – selected issues

The ECB’s monetary policy has received considerable attention in recent years. This is less the case, however, for its regular monetary policy preparation and decision-making process. This paper reviews how the factors usually considered as critical for the success of a central banking system and the federal nature of the Eurosystem are intertwined with its overall design and the functioning of its committee architecture. In particular, it examines the procedures for preparing monetary policy decisions and the role of the decision-making bodies and the committees therein. We suggest that technical committees, involving all national central banks (NCBs), usefully contribute to the regular processing of a vast amount of economic, financial and monetary data, as well as to the consensus building at the level of the Governing Council. A federal organisational structure, including a two-tier committee structure with the Executive Board taking the lead in preparing the monetary policy decisions and the Governing Council in charge of the decisions with collective responsibility for them, as well as committee work at the various hierarchical levels, contributes to the efficiency of the ECB’s monetary policy decision-making, and thereby facilitates the maintenance of price stability in the euro area. A fully-fledged committee structure has also contributed to the smooth integration of non-euro area Member States into the Eurosystem’s monetary policy decision-making process.
