Regional Business Cycle Synchronization in Europe? Bruges European Economic Research (BEER) Papers 11/June 2007

We analyse regional business cycle synchronization in the Euro Area, using Gross Value Added in 53 NUTS 1 regions for a period of thirty years (1975-2005), detrended by Hodrick-Prescott and the Christiano-Fitzgerald filters. We conclude that, on average, synchronization has increased for the period considered with exceptions during the eighties and the beginning of the nineties. Still, the correlation of the business cycle in some regions with the benchmark remained low or even decreased. Our findings also support the hypothesis of the existence of a ‘national border’ effect.

Cross-country insurance mechanisms in currency unions. Bruegel Working Paper 2014/04, 27 March 2014

Countries in a monetary union can adjust to shocks either through internal or external mechanisms. We quantitatively assess for the European Union a number of relevant mechanisms suggested by Mundell’s optimal currency area theory, and compare them to the United States. For this purpose, we update a number of empirical analyses in the economic literature that identify (1) the size of asymmetries across countries and (2) the magnitude of insurance mechanisms relative to similar mechanisms and compare results for the European Monetary Union (EMU) with those obtained for the US. To study the level of synchronization between EMU countries we follow Alesina et al. (2002) and Barro and Tenreyro (2007). To measure the effect of an employment shock on employment levels, unemployment rates and participation rates we perform an analysis based on Blanchard and Katz (1992) and Decressin and Fatas (1995). We measure consumption smoothing through capital markets, fiscal transfers and savings, using the approach by Asdrubali et al. (1996) and Afonso and Furceri (2007). To analyze risk sharing through a common safety net for banks we perform a rudimentary simulation analysis. |

Supporting the Revolution: America, Democracy, and the End of the Cold War in Poland, 1981-1989. ACES Working Paper (Report) No. 8, 2007

Early on the morning of December 13, 1981, General Wojciech Jaruzelski, the leader of the communist Polish United Workers' Party (PZPR), declared martial law, ending the so-called "Polish Crisis," which began with the creation of the Independent Free Trade Union "Solidamosc" in August 1980. Over the next eight years, the Communist government and the opposition struggled over power, culminating in 1989 with the creation of a Solidamosc-led government which ended fifty years of Communist rule in Poland and led the way to further democratic revolutions throughout Eastern Europe. The purpose of this dissertation is to utilize newly available and underutilized archival sources as well as oral history interviews, from both international and American perspectives, to fully chronicle American policy toward Poland from the declaration of martial law until the creation of the Solidarnosc government. Rather than explaining Polish-American relations in bilateral terms, the dissertation illuminates the complex web of influences that determined American policy in Washington and affected its implementation within Poland. This includes descriptions of internal tensions within the Reagan administration, differences between American decisions in Washington and implementation in Warsaw, lobbying from Polish-American groups, clashes between Capitol Hill and the White House, coordination with American labor organizations to support Solidarnosc, disagreements with West European allies in NATO and international financial organizations, cooperation with the Vatican and the Polish Catholic Church, synchronization with American humanitarian organizations working in Poland, limitations caused by the realities of Soviet power in Eastern Europe, and complications caused by domestic Polish concerns. By taking a broad view of American policy and highlighting internal Polish decisions, with both the Communist government and the democratic opposition, the dissertation provides concrete examples of America's role in Poland's transformation, arguing, however, that this role was very limited. These conclusions are relevant to arguments about the end of the Cold War, the nature of American power, as well as current discussions about possibilities to promote democracy within hostile regimes.

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.
