One money with several cycles? Evaluation of European business cycles using cluster analysis. ACES Cases No. 2009.3

Optimal currency area theory suggests that business cycle comovement is a sufficient condition for monetary union, particularly if there are low levels of labour mobility between potential members of the monetary union. Previous studies of co-movement of business cycle variables (mainly authored by Artis and Zhang in the late 1990s) found that there was a core of member states in the EU that could be grouped together as having similar business cycle comovements, but these studies always used Germany as the country against which to compare. In this study, the analysis of Artis and Zhang is extended and updated but correlating against both German and euro area macroeconomic aggregates and using more recent techniques in cluster analysis, namely model-based clustering techniques.

Measuring the intermittent synchronicity of macroeconomic growth in Europe. ACES Cases No. 2010.1

Synchronization of growth rates are an important feature of international business cycles, particularly in relation to regional integration projects such as the single currency in Europe. Synchronization of growth rates clearly enhances the effectiveness of European Central Bank monetary policy, ensuring that policy changes are attuned to the dynamics of growth and business cycles in the majority of member states. In this paper a dissimilarity metric is constructed by measuring the topological differences between the GDP growth patterns in recurrence plots for individual countries. The results show that synchronization of growth rates were higher among the Euro area member states during the second half of the 1980s and from 1997 to roughly 2002. Apart from these two time periods, Euro area member states do not appear to be more synchronized than a group of major international countries, signifying that globalization was the major cause of international business cycle synchronization.

Europe on the Road to the Third Stage of EMU: Recent Evidence. CES Germany & Europe Working Papers, No. 07.2, 1996

The paper deals with Europe's effort to proceed to the thud stage of EMU and establish a common currency. It is argued that the success of the common currency experiment will greatly depend on the fulfillment of the Optimum Currency Area (OCA) criteria, on the adoption of the proper adjustment policies as well as on the political desirability of the project. The paper is organized as follows: Section 1 deals briefly with the index of criteria that define an OCA. Section 2 examines the extent to which Europe experiences common demand disturbances, while sections 3 and 4 focus on evidence about the mobility of factors of production across Europe, namely labor and capital. Section 5 examines the possibility of an increase in trade volume across the EU under fixed exchange rates or a common currency regime. Section 6 sheds light on the possibility of the EURO (the ex-ECU} to become a vehicle currency in the international financial system, and Section 7 is concerned with the benefits and costs of the establishment of a European Central Bank (ECB), paying special attention to seigniorage revenues. Section 8 deals with the necessity of establishing an EU federal mechanism facilitating adjustment. Section 9 sketches out a proper role for a hegemonic power in a common currency regime. Finally, section 10 examines EMU prospects during the transitional period. The paper closes with some concluding remarks, where the role of politics and coordination of economic policies are particularly emphasized as of cardinal importance on the road to the third stage of EMU.

A parallel currency for Greece. CEPS High-level Brief, 20 May 2015

Greece and its creditors seem to be engaged in a game of chicken: both sides expect the other to yield at the last moment. The game will almost certainly end with each side deviating somewhat from its preferred course. This High-Level Brief discusses how a parallel currency could contribute to a resolution of the conflict. In the author's view, it would be the least-bad option for both sides among three possible options on the table.

The Fate of Greece in a ‘Genuine Economic and Monetary Union’: Lessons from a small island state. CEPS Hi-Level Brief, 19 June 2015 Friday, 19 June 2015

As the Greek debt drama reaches another supposedly decision point, Daniel Gros urges creditors (and indeed all policy-makers) to think about the long term and poses one key question in this CEPS High-Level Brief: What can be gained by keeping Greece inside the euro area at “whatever it takes”? As he points out, the US, with its unified politics and its federal fiscal transfer system, is often taken as a model for the Eurozone, and it is thus instructive to consider the longer-term performance of an area of the US which has for years been kept afloat by massive transfers, and which is now experiencing a public debt crisis. The entity in question is Puerto Rico, which is an integral part of the US in all relevant economic dimensions (currency, economic policy, etc.). The dismal fiscal and economic performance of Puerto Rico carries two lessons: 1) Keeping Greece in the eurozone by increasing implicit subsidies in the form of debt forgiveness might create a low-growth equilibrium with increasing aid dependency. 2) It is wrong to assume that, further integration, including a fiscal and political union, would be sufficient to foster convergence, and prevent further problems of the type the EU is experiencing with Greece.

The Euro as a Foreign Currency for Greece Friday, 19 June 2015

In contrast to his contribution just a month ago, which examined how a Greek parallel currency to the euro could allow the Greek government to gain some room for manoeuver in fiscal policy while at the same time continuing the adjustment programme demanded by the country’s creditors, Thomas Mayer explores in the present note the question of how the Greek population could still keep the euro after a default of its government. Contrary to general belief, he finds that Grexit and the reintroduction of the euro as a foreign currency would probably be positive for the Greek economy, although its creditors would be hard hit. It is therefore primarily in their interest that default and Grexit are avoided.

The Greek economy is unlikely to benefit from further devaluation. CEPS Commentary, 3 July 2015

Martin Wolf offers an excellent analysis of how the Greek voter may feel about Sunday’s referendum.1 There is no good option: either be engulfed in the chaos following the rejection of the programme, exit and collapse of the economy or accept another programme.

The Drivers of Current Account Surplus in Germany and the Politics of Rebalancing in the Eurozone. EU Centre, Singapore Working Paper No. 24, April 2015

Current account deficits have caught the public’s attention as they have contributed to the European debt crisis. However, surpluses also constitute an issue as a deficit in any country must be financed through a surplus in another country. In 2013, Germany, now the world’s largest surplus economy, registered a record high US$273 billion surplus. This paper looks at what accounts for Germany’s surplus, revealing that the major driving factors include strong global demand for quality German exports, domestic wage restraint, an undervalued single currency, high domestic savings rate and interest rate convergence in the euro area. This paper echoes the US Treasury’s view that a persistent German surplus makes it harder for the eurozone as a whole and the southern peripheral economies in particular to recover from the current financial crisis by imposing a Europe-wide “deflationary bias” through pushing up the exchange rate of the euro, exporting feeble German inflation and projecting its ultra-tight macroeconomic policies onto crisis economies. This paper contends that Germany’s trade surplus is likely to endure as Germany and other eurozone countries uphold diverging views on the nature of the surplus engage in a blame-game amidst a sluggish rebalancing process. Prizing the surplus as a reflection of hard work and economic competitiveness, German authorities urge their southern eurozone colleagues to undertake bold structural reforms to correct the imbalance, while the hand-tied governments in crisis-stricken economies call on Germany to do its “homework” by boosting German demands for European goods and services.

An essential partner in the background. Europe in China's policy during the rule of Xi Jinping. OSW STUDIES 56 2016

Chinese elites do not treat Europe as an equal partner and are convinced that China holds the upper hand over Europe. They see a growing asymmetry in bilateral relations. China’s sense of its own potential is boosted by internal divisions within the European Union. At the same time, Europe is China’s key economic partner and an ‘economic pillar’ supporting China’s growth on the international stage. Beijing strives to maintain Europe’s open attitude towards the Chinese economy, in particular its exports, technology transfer to China, location of investments and diversification of China’s currency reserves. Cooperation with Europe and support from Europe are necessary to enable China to improve its position in the international economic and financial system, mainly in order to legitimise China’s actions in the area of multilateralism and global governance. Similarly, Beijing attaches great importance to maintaining Europe’s non-involvement in two issues: China’s core interests and Chinese-American relations.
