External imbalances within the Eurozone grew substantially between the introduction of the euro in 1999 and the global financial crisis of 2008–09. Using new empirical evidence, this column argues that imbalances in the Eurozone periphery were mainly driven by a domestic demand boom, triggered by greater financial integration, with changes in the periphery’s competitiveness playing only a minor role. Internal devaluation may thus have been of limited effectiveness in restoring external balances, although better external competitiveness may eventually boost medium-term growth.

Before the introduction of the euro, it was hoped that by promoting increased intra-regional trade it would increase business-cycle synchronisation within the Eurozone, and thus help it to fulfil the criteria for an optimum currency area. This column presents recent research that compares the evolution of business-cycle synchronisation in the Eurozone and east Asia. While the euro has had some impact on business-cycle synchronisation in the Eurozone, it has done so not through increased intra-regional trade intensity, but rather through some other channel – most likely financial integration.

Nicholas Crafts talks to Viv Davies about his recent work on the threatening issue of public debt in the Eurozone. Crafts maintains that the implicit fault line in the EZ is evident; several EZ economies face a long period of fiscal consolidation and low growth and that a different sort of central bank might be preferable. They also discuss the challenges and constraints of banking, fiscal and federal union. The interview was recorded in London on 17 January 2014.

Fiscal sustainability has become a hot topic as a result of the European sovereign debt crisis, but it matters in normal times, too. This column argues that financial sector reforms are essential to ensure fiscal sustainability in the future. Although emerging market reforms undertaken in the aftermath of the financial crises of the 1990s were beneficial, complacency is not warranted. In the US, political gridlock must be overcome to reform entitlements and the tax system. In the Eurozone, creating a sovereign debt restructuring mechanism should be a priority.

Though in the past two years substantial progress has been made in completing the structure of Europe’s Economic and Monetary Union, not all economic inconsistencies have been solved. This column discusses three main challenges that still need to be addressed. First, sound fiscal policies need to be conducted while keeping sustainable welfare systems. Second is the conflict between policy objectives and economic realities – vulnerable economies cannot reduce their debts and simultaneously gain competitiveness. Third, financial stability and integrated financial markets cannot be established unless the relationship between banks and their sovereigns is reformed. Addressing each of these challenges is important, and it could benefit all Eurozone members.

On 19 October 2010, Angela Merkel and Nicolas Sarkozy agreed that in future, sovereign bailouts from the European Stability Mechanism would require that losses be imposed on private creditors. This agreement was blamed for the increase in sovereign spreads in late 2010 and early 2011. This column discusses recent research on the market reaction to the surprise announcement at Deauville. With the exception of Greece, the rise in spreads was within the range of variability established in the previous 20 days.

The Eurozone crisis exposed weaknesses in the Eurozone’s design. This column – by Nobelist Joe Stiglitz and World Bank Chief Economist Kaushik Basu – argues that the Eurozone’s financial architecture can be improved by amending the Treaty of Lisbon to permit appropriately structured cross-country liability for sovereign debt incurred by EZ members.

This column argues that the legacy of public debt resulting from the crisis in the Eurozone is a serious threat. Both the size of the problem and the options to address it make life much more difficult for policymakers than was the case in the late 1930s after the collapse of the gold standard. For some countries, a ‘subservient’ central bank might be preferable to the ECB.

Labour mobility is one of the keys to a successful currency union – be it within or across nations. This column discusses new evidence showing that the shock-absorbing role of migration has increased in Europe and declined in the US. During the Great Recession, European migration remained high – although not high enough given the vast differences across the Eurozone. Overall, Europe has strengthened this essential adjustment mechanism.

During the recent turmoil in the Eurozone, little attention has been paid to one of the euro’s founding objectives – price convergence. This column argues that the euro has in fact been very successful in this regard. In a study of the pricing behaviour of Apple, IKEA, H&M, and Zara, the authors find that price dispersion is 30–50% lower for countries in a currency union than for those with a fixed exchange rate.

The sustainability of government debt cannot be determined with certainty. This column presents an early warning indicator to predict sovereign debt crises using a stochastic simulation framework. What counts is the risk of a significant rise in public debt, more so than the expected evolution of the debt level. A key determinant of the indicator is the quality of budgetary policies in controlling the government budget in the event of adverse shocks.

Having promised to do ‘whatever it takes’ to ensure the survival of the euro, the ECB now faces the problem of record high unemployment combined with a strong currency. There is accumulating evidence that the ECB is more willing to fight currency appreciation than the Bundesbank would have been. Capital inflows have been a key source of recent upward pressure on the euro. Should this continue, the ECB may need to intervene more aggressively in order to promote economic recovery in the Eurozone.

Since the advent of the Eurozone sovereign-debt crisis, economic commentators have drawn attention to macroeconomic imbalances within the Eurozone. This column presents evidence on the link between macroeconomic imbalances and differences in culture – or more specifically, interpersonal trust. A conservative estimatation suggests that a one standard-deviation increase in trust reduces macroeconomic imbalances by about a quarter of a standard deviation. Moreover, differences in interpersonal trust can explain a fifth of the variation in intra-Eurozone imbalances.

Many Eurozone banks are still in a fragile state following the Global Crisis. This vulnerability will be highlighted as the ECB takes charge of bank supervision, and the EZ moves towards a banking union. This column proposes a Eurozone bank restructuring agency as a way to speed up the crisis resolution. This temporary, centralised agency would be in charge of restructuring viable and non-viable banks throughout the Eurozone. Solving the problem of legacy assets is a necessary step towards a banking union.

Sovereign bankruptcies occur regularly and violently. The nature of sovereign-debt problems has changed in comparison to ten years ago. This column discusses policy proposals to better resolve debt crises and prevent them from happening in the future. Such proposals are given both for the Eurozone, and at a global level.

The EZ crisis increased north-south conflicts between bailout providers and recipients – especially between Germany and Greece. This column shows evidence that political conflict directly translated into losses of market share for German car producers in Greece – especially in areas where German armed forces committed massacres during World War II. Six decades later, memories of conflict are never far from the surface in Europe.

Much has happened since VoxEU published an eBook on the banking union in Europe one year ago. In this column, the editor of the eBook reviews the developments and plans of the past year. Many of the issues flagged by eBook contributors are still relevant and have not yet been addressed. While immediate pressures seemed to have receded, the crisis is still very much with us and is still awaiting resolution.

The European sovereign-debt crisis has raised many questions regarding the link between sovereigns and banks. This column goes to the heart of one and shows that tensions in Eurozone government-bond markets were transmitted internationally through the bank lending channel. Lending by European banks with sizeable exposures to sovereign debt from the troubled Eurozone countries became impaired after the start of the crisis, resulting in a reallocation away from foreign (especially US) markets.

The Eurozone has been going through an existential crisis since 2010. The column discusses research that draws an analogy between the careful planning in the 1980s leading to the creation of the euro and the planning that led to the Bretton Woods system. The outcome for the Eurozone, as in the earlier creation of a man-made international system, may be similar – collapse or at least major reworking.

The doom-loop between banks and the national governments played a dominant role in the Eurozone crisis for Ireland and Cyprus. A Eurozone banking union is usually viewed as the solution. This column argues that the doom-loop cannot be undone as long as banks hold oversized amounts of their government’s debt. A simple solution would be to apply the general rule that banks are prohibited from holding more than a quarter of their capital in government bonds of any single sovereign.
