The euro’s impact on southern EZ members is a key topic in national and European debates. This column argues that the economic evidence is twisted to fit preconceptions. It presents evidence based on the ‘synthetic control’ approach, finding that the euro raised trade, lowered interest rates and inflation, but had a small negative impact on per capita incomes.

As banks repay their loans from the Long-Term Refinancing Operation, the ECB’s balance sheet is shrinking. This column argues that, given the slow recovery and sustained low inflation, the ECB should replace its bank lending programme with quantitative easing. Buying short-term government debt would be consistent with the ECB’s inflation target, would keep the ECB’s monetary policy separate from its role in bank supervision, and would create a built-in exit strategy from unconventional policy.

Large flows of bank lending from core countries in the Eurozone to the periphery lead to large financial imbalances. This column explains what motivated such financial flows. With the advent of the Eurozone, banks in core countries gained relative advantage in lending to the periphery, making such lending very attractive. They also served as intermediaries for financial flows from outside the Eurozone to the periphery. Now – five years since the start of the euro crisis – Eurozone financial markets remain segmented.

Some view the improvements in current accounts for Greece, Italy, Portugal, and Spain as short-lived – the result of a temporary compression of import demand that is likely to be reversed as the recession eases. This column argues the contrary, based on the fact that their improving trade balances reflect better export performance. This development points toward a fundamental stabilisation of the competitiveness of these economies.

Although progress has been made on resolving the Eurozone crisis – vulnerable countries have reduced their current-account deficits and implemented some reforms – more still needs to be done. This column argues for a ‘consistent trinity’ of policies: structural reforms within countries, more symmetric macroeconomic adjustment across countries, and a banking union for the Eurozone.

Agnès Benassy-Quéré, Shahin Vallee, Thursday, March 27, 2014

The recent crisis has highlighted some problems in the current structure of the Eurozone, such as the lack of political integration. This column introduces the Eiffel group – a group of French experts – and its call for a ‘political community of the euro’. The economic and political rationales behind the proposal are discussed in detail. This proposal (also shared by experts in other countries) calls for a debate about the architecture and institutions underpinning the European Monetary Union.

Since 2007, there has been a buildup of TARGET imbalances within the Eurosystem – growing liabilities of national central banks in the periphery matched by growing claims of central banks in the core. This column argues that, rather than signalling the collapse of the monetary system – as was the case for Bretton Woods between 1968 and 1971 – these TARGET imbalances represent a successful institutional innovation that prevented a repeat of the US payments crisis of 1933.

Daniel Gros, Wednesday, March 19, 2014

Since the onset of the sovereign debt crisis, the argument for a system of fiscal transfers to offset idiosyncratic shocks in the Eurozone has gained adherents. This column argues that what the Eurozone really needs is not a system which offsets all shocks by some small fraction, but a system which protects against shocks which are rare, but potentially catastrophic. A system of fiscal insurance with a fixed deductible would therefore be preferable to a fiscal shock absorber that offsets a certain percentage of all fiscal shocks.

The European Resolution Fund is intended to reach €55 billion – much less than the amount of public assistance required by individual institutions during the recent financial crisis. This column argues that the Resolution Fund can nevertheless be large enough if it forms part of a broader architecture resting on four pillars: prudential regulation and supervision, ‘no forbearance’, adequate ‘reserve capital’, and provision of liquidity to the bank-in-resolution. By capping the Resolution Fund, policymakers have reinforced the need to ensure that investors, not taxpayers, bear the cost of bank failures.

A popular view among economic commentators is that rich countries face a serious risk of deflation, and should adopt aggressive macroeconomic stimulus policies to ward it off. This column argues that despite similar headline inflation rates, the US, Europe, and Japan in fact face very different macroeconomic conditions. In the US, much of the recent disinflation is attributable to positive supply-side developments. In Europe, an aggressive round of quantitative easing might encourage policymakers to delay the reforms that are necessary to avoid a prolonged Japanese-style malaise.

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, Tuesday, January 21, 2014

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.

Willem Buiter, Friday, January 10, 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.

Marco Buti, Wednesday, January 8, 2014

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.

Kaushik Basu, Joseph Stiglitz, Thursday, January 2, 2014

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.

Nicholas Crafts, Friday, December 13, 2013

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.

Alberto Cavallo, Brent Neiman, Roberto Rigobon, Friday, November 29, 2013

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.
