Throughout the Eurozone’s economic crisis, little attention has been given to wage-setting practices. This lack of attention is surprising given that wages have been considered an important instrument for managing the economy in a currency union since the 1960s and have even been emphasized in successive blueprints for Economic and Monetary Union (EMU). Recent scholarship has found differences in wage-setting practices a key feature distinguishing healthy and crisis-stricken Eurozone countries. Indeed, in this emerging literature, countries that coordinate wages effectively have remained competitive under EMU and had fewer troubles in responding to the crisis, while those with weakly-coordinated wages have struggled mightily. In effect, this literature finds differences in EMU members’ wage-setting regimes at the heart of the economic crisis now facing the Eurozone and the trade imbalances between its Northern and Southern members. However, very little work has examined the specifics of individual labour market models under EMU. Indeed, while this new literature on wage setting and the crisis places wage setting models at its centre, it does not delve into the differences among highly coordinated systems. This oversight is problematic given that scholars of monetary union have suggested that the single currency may amplify the effects of subtle differences in national socioeconomic models, while others have suggested that EMU may be corrosive to some labour market models that coordinate wage setting. This study addresses this gap in the literature, dissecting labour market models by the mechanisms that deliver horizontal and vertical coordination, as well as the indicators to which they are calibrated. Using this framework, it then traces the experiences of Belgium, Germany and the Netherlands under EMU, who use very different mechanisms to coordinate wages. It argues that while EMU has exacerbated longstanding problems in the Belgian wage-bargaining system, it has had little impact upon the German and Dutch systems. Rather, underlying changes in the institutions that manage wage setting in these countries, and changes in social partner organizations – particularly the trade unions – are far more consequential for their continued functioning under EMU. More broadly, these findings suggest that in fact, many designs of highly coordinated wage setting are capable of managing pressures from the single currency. For those Eurozone countries currently refashioning their labour market models, tighter coordination may be just as viable an option as dismantling their wage-bargaining institutions. / Graduate / 0615 / ifdumka@gmail.com

Syftet är att undersöka om Sverige tillsammans med ett eller flera av de nordiska länderna kan utgöra en optimal valutaunion. Utifrån ett svenskt perspektiv visar resultaten att det är lämpligast för Sverige att ingå i en valutaunion med Norge och Danmark eftersom den ekonomiska integrationen mellan dessa länder har varit störst. Taylors ränteregel visar att Sverige och Norges räntebanor samvarier mest och Optimal currency area-index (OCA-index) visar att Sverige, Danmark och Norge präglas av störst ekonomisk integration. Vi har använt två olika metoder för att undersöka en optimal nordisk valutaunion utifrån ett svenskt perspektiv, OCA-index och Taylors ränteregel. De båda tillvägagångssätten fokuserar på hur ekonomiskt integrerade länderna är, men genom olika variabler och ekonomiska storheter. Ett OCA-index har skapats och skattningen visar att variabeln som beskriver konjunkturcykeln är den som har störst inverkan på den beroende variabeln, växelkursvolatilitet. För att undersöka hur de nordiska länderna har påverkats av chocker har taylor-räntor beräknats och skillnader i korrelation har analyserats. Analysen visar på svårigheter i att mäta ekonomisk integration, något som OCA-teorin hävdar är viktigt för en optimal valutaunion. Beroende på vilken utgångspunkt som väljs varierar resultatet för vilket land Sverige skulle kunna bilda en optimal valutaunion med. Resultaten skiljer sig från tidigare forskning, delvis i tolkningen av variabeln för exportsektorsammansättning och delvis på grund av den studerade tidsperioden. / The aim is to investigate if Sweden constitutes a possible optimal currency area with one or more of the Nordic countries. The results show that Norway and Denmark are the two most suitable partners to join Sweden in a currency union since the economic integration between these countries is the strongest. The Taylor interest rate rule indicates that the interest rate paths between Sweden and Norway correlate the most. The variables in the optimal currency area-index (OCA-index) show that it is Sweden, Denmark and Norway that enjoys the strongest economic integration and therefore constitutes a possible optimal currency area. Two different methods have been used to investigate the possibility of an optimal currency area; the OCA-index and the Taylor interest rate rule. Both methods focus on the level of economic integration between the countries but do this by assessing different economic variables. The OCA-index has been compiled and the estimation indicates that the variable describing the business cycle has the greatest impact on the dependent variable, exchange rate volatility. In order to examine how the Nordic countries have been affected by shocks, Taylor interest rates have been calculated and differences in correlation have been examined. The conducted analysis points toward difficulties measuring economic integration, which according to the OCA-theory is important for an optimal currency union. There are several consistencies between the results of the two methods but also important differences such as which country would be the best partner in a currency union with Sweden. The findings differ from earlier scientific results mostly regarding the interpretation of the variable describing the export sectorial composition and the considered time period.

Asian efforts towards bond market development are driven by the 1997-98 financial crises; Central and Eastern European efforts by the transition towards EMU. The small size of most of the economies underlying these still "emerging" bond markets poses the question of minimum efficient scale and which options to pursue. We argue that the joint bond funds and regional bond market linkups that follow existing trade, FDI and bank ties will broaden the sources of finance, can improve market discipline, provide signals to the market, and thus increase financial stability. Based upon bond market data and analysis of regional efforts like the Asian Bond Funds, we argue that bond market development should be given more attention to foster growth and stability.

In the 2003 Treaty of Accession, the signatories agreed that all New Member States (NMS) that joined the European Union (EU) in 2004, would adopt the euro, even if no timetable was provided. Why have some NMS not been able to join the euro area even if they made serious attempts at the outset? What are the circumstances and policies in these countries that have led them not yet to adopt the euro? Has it been lack of political will on the part of the government, a strong voice in the opposition, a euroskeptic president, insufficient administrative capacity, or lack of policy learning? Though there is no consensus among economists as to whether or not adopting the euro in the short run is a good idea, an economic cost-benefit analysis would suggest that in the long run euro adoption is positive for NMS. Yet, macroeconomic analyses cannot explain the change in government policies that may lead to euro adoption. Political scientists have typically focused on collective identity, policy learning, ideas and knowledge transfer among central bankers and other political elites, as well as adjustment to global pressures and Europeanization. This political science literature is unable to provide a satisfactory explanation as to why the Czech Republic, Hungary and Poland have not adopted the euro yet. I argue that the role of domestic politics is key to explaining the process of euro adoption in Czech Republic, Hungary and Poland: government policies, elections, electoral cycles as well as constitutional rules, veto points, central banks, public opinion and the media turn out to be crucial in explaining the lagging euro adoption process in these countries. / Graduate

Cette thèse analyse la convergence au sein d’une union monétaire par l’intermédiaire de la dynamique des prix et des taux de change d’équilibre. Dans le premier chapitre nous présentons les caractéristiques générales des zones monétaires, ainsi que l’historique de celles que nous étudions : l’UEM et la zone CFA. Le deuxième chapitre traite de la convergence des prix au sein de la zone euro par le biais de modèles à transition lisse. La convergence est non-linéaire, et les vitesses d’ajustements sont différentes selon les pays. Ceci s’explique par les différences dans l’évolution de la compétitivité-prix, les rigidités du marché du travail, mais aussi les schémas de spécialisation. Le troisième chapitre évalue la validité de la Parité des Pouvoirs d’Achat absolue au sein de l’UEM à travers des tests de racine unitaire et de cointégration en panel de deuxième et de troisième générations. Dans l’ensemble, la dynamique des prix apparaît hétérogène et dépendante des périodes d’évolution de l’UEM ainsi que des groupes de pays considérés. Le quatrième chapitre relie les déséquilibres externes à la crise de la dette souveraine que connait l’UEM depuis 2009. Nous montrons que lorsqu’un pays appartenant à une union monétaire fait face à un déséquilibre externe vis-à-vis d’un autre pays membre, l’écart de taux d’intérêts correspondant tend à s’accroître. De plus, lorsque ces déséquilibres persistent, ils peuvent déclencher une crise de la balance des paiements. Enfin le dernier chapitre s’intéresse à la pérennité de la zone CFA. En comparant cette dernière à un échantillon composé d’autres pays d’Afrique Subsaharienne, nous mettons en évidence que malgré son non-respect des critères d’optimalité, la zone CFA a favorisé les équilibres internes et externes, et facilité les ajustements aussi bien au niveau de l’ensemble de la zone, qu’au niveau individuel. Ceci laisse penser que cette union est soutenable. / This thesis analyses the convergence among a monetary union through the price dynamics and the equilibrium exchange rates. In the first chapter we introduce the main characteristics of the monetary areas, as well as the history of those under study: the EMU and the CFA franc zone. The second chapter deals with the price convergence inside the Eurozone via smooth transition regressions. This process is non-linear, and adjustment speeds are dissimilar depending on the countries. It is explained by the differences in the evolution of price competitiveness, labor market rigidities, but also specialization patterns. The third chapter investigates the validity of the absolute Purchasing Power Parity within EMU thanks to second and third generation panel unit root and cointegration tests. On the whole, price dynamics seems to be heterogeneous and depends on the EMU period and group countries considered. The fourth chapter links external disequilibria to the sovereign debt crisis experienced by EMU since 2009. We exhibit that when a country belonging to a monetary union faces an external disequilibrium relative to its main partner, the interest rates spread tends to increase. Moreover, when these disequilibria are persistent, they may trigger a balance of payments crisis. Finally, the last chapter pays attention to the permanence of CFA franc zone. By comparing the latter to a sample of other Sub-Saharan African countries, we evidence that the CFA franc zone has fostered external and internal balances, facilitated adjustments in the zone as a whole, as well as in each of its member, even if it does not fulfill the optimality criteria. This suggests that the union is sustainable.

This paper summarizes the main Optimum Currency Area Theories (AMO), in order to use this branch of regional integration, to verify the configuration, in a cluster scenario, the euro area member countries during the period 2002-2013, from the perspective of macroeconomic imbalances factors, evidenced by the euro crisis, recent. Therefore, making use of statistical methods of multivariate analysis, and, factor analysis and cluster analysis were allowed to result in that during the period before the outbreak of the euro crisis had agreater concentration of countries in the first group, composed of countries more mature and more competitive economy. However, during the most turbulent crisis years, there is a greater amount of the groups formed by making the first less concentrated and dispersed in the composition of the other group. Only in the last two years of observation, 2012 and 2013, we find again a concentration of member countries in a group, then it is observed that in the years most critical crisis, show up macroeconomic disparities in the euro zone countries. Thus, the research contributes in order to verify, by means of multivariate analysis every year, over a period of time, and contrast with the reality that reaches the monetary union in Europe, to confirm that the disparities that existed before the outbreak of the crisis, and continue to exist between the members of the currency area. Confirming that the convergence criteria has not stopped economic disparities were reduced. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / O presente trabalho faz um resumo das principais Teorias de Área Monetária Ótima (AMO), de modo a utilizar este ramo de integração regional, para verificar a configuração, em um panorama de agrupamento, dos países-membros da área do euro, durante o período de 2002 a 2013, pela ótica de fatores de desequilíbrios macroeconômicos, evidenciado pela crise do euro, recente. Logo, fazendo uso de metodologias estatísticas de análise multivariada, mais precisamente, análise fatorial e análise de agrupamento, permitiu-se resultar em que durante o período anterior à eclosão da crise do euro havia uma maior concentração de países no primeiro grupo, composto por países de economia mais madura e mais competitiva. Entretanto, durante os anos mais turbulentos de crise, observa-se uma maior quantidade de grupos formados, tornando o primeiro grupo menos concentrado e disperso na composição dos demais. Apenas nos dois últimos anos observados, 2012 e 2013, verifica-se novamente uma concentração de países-membros em um grupo, logo se observa que nos anos mais críticos de crise, evidenciam-se as disparidades macroeconômicas dos países da zona do euro. Assim, a pesquisa contribui no sentido de verificar, por meio de análise ultivariada ano a ano, ao longo de um período de tempo, e contrastar com a realidade que atinge a união monetária na Europa, ao confirmar que as disparidades, que já existiam antes da eclosão da crise, e continuam a existir entre os integrantes da área monetária. Confirmando que os critérios de convergência não impediu que as disparidades econômicas fossem diminuídas.

Afin de répondre au questionnement général de cette thèse qui traite de la viabilité de l'union monétaire européenne, ce travail est divisé en trois parties. Dans la première, nous analysons notre objet d'étude à un niveau méta. Nous montrons ainsi que l'architecture institutionnelle de la zone euro est axée sur la stabilité monétaire sans proposer formellement des mécanismes d'ajustement aux chocs. La deuxième partie s'intéresse à la question de la synchronisation des économies européennes par l'intermédiaire de deux essais. Nous montrons que d'importantes hétérogénéités demeurent. La troisième partie analyse des questions relatives à la transmission de la politique monétaire. Cela se réalise avec deux essais qui montrent d'une part que la transmission de la politique monétaire dans la zone euro a été fortement perturbée par la crise des subprimes et, d'autre part, que l'influence de la BCE sur les actions des marchés européens est faible. Cette thèse insiste par conséquent sur le caractère incomplet du processus d'intégration économique et monétaire européen et sur sa nécessaire réforme. / The main objective of this thesis is to investigate the problematic of the viability of the European monetary union. This work is divided in three parts. In the first one, we analyse our object of research in order to precise several research axes to study in priority. We show that the European monetary union in mainly focused on the monetary stability without any formal adjustments mechanisms. The second part is focused on the question of the European members' economies synchronisation. We show that large heterogeneities remain. Two essays on the monetary policy pass-through compose the third part. We demonstrate that the interest rate pass-through was affected by the subprimes crisis and that the ECB's influence over the European stock markets is weak. This thesis insists on the fact that the European monetary and economic process of integration is incomplete and should be reinforced.
