Peter Praet: Improving the functioning of Economic and Monetary
Union - lessons and challenges for economic policies
Keynote dinner speech by Mr Peter Praet, Member of the Executive Board of the European
Central Bank, at the NABE (National Association for Business Economics) International
Symposium "Global Recovery: The Good, the Bad and the Ugly", Madrid, 16 April 2018.

The ongoing economic expansion shows that our monetary policy has been effective in laying the
1
groundwork for a return of inflation to a rate below, but close to, 2% over the medium term.
Euro area real GDP has expanded for 19 consecutive quarters. The latest economic data and
survey results point towards some moderation of late, following several quarters of very strong
growth Inflation developments, however, remain subdued, and we have not yet met the
Governing Council's three criteria - convergence, confidence and resilience - for a sustained
adjustment in the path of inflation, which is our stated condition for ceasing our net asset
purchases. Overall, an ample degree of monetary stimulus remains necessary for underlying
inflation pressures to continue to build up and support headline inflation developments over the
medium term. Hence, we must be patient, persistent and prudent with our policy.
Our monetary policy has effectively contributed to euro area macroeconomic adjustment through
the staunch pursuit of our price stability mandate. Monetary policy, however, is only one side of
the story. Price stability is a necessary, but not a sufficient condition for sustained and balanced
growth in Europe. The run-up to the crisis proved that macroeconomic imbalances can grow
amid price stability (see Figure 1 and 2), highlighting the need to keep economic policy high on
Europe's agenda.
Tonight I would like to concentrate on economic policies and their essential role in ensuring a
smooth functioning of Economic and Monetary Union (EMU). I will look back at the experience of
the euro area since 1999 and illustrate the emergence of macroeconomic imbalances by
focusing on three countries: Spain, Germany and France.
The crisis acted as a litmus test for Europe's institutional framework, revealing the need for a
number of institutional reforms. Lessons have been learned and significant progress towards
strengthening EMU has been achieved, including elevating the responsibility of banking
supervision from national to the European level, the creation of the European Stability Mechanism
as a permanent crisis management institution, and improvements in the EU surveillance
2
framework for economic policies. Progress towards completing the banking union and the
capital markets union has rightly emerged as one of the immediate priorities in strengthening
EMU, not least as such progress is seen as crucial in supporting macroeconomic adjustment in
a monetary union.
Today it is fair to say that the euro area has lived up to the challenges posed by the existential
crisis and euro area countries have displayed a strong commitment to EMU. Macroeconomic
adjustment in EMU has made significant progress, with countries implementing significant
growth-enhancing reforms and correcting external imbalances, but this process has been
difficult. Countries most affected by the crisis were confronted with significant hardship, even
though financial support provided by the Union and its Member States to countries facing acute
financing difficulties prevented catastrophic outcomes and cushioned some of its impact by
providing time for economic adjustment. Looking forward, in order to sustain a high level of social
welfare in the long term, it is essential for euro area countries to improve their capacity to prevent
crisis and hence to ensure that macroeconomic adjustment progresses in a smoother way.
The emergence of macroeconomic imbalances
The crisis has demonstrated how persistent losses in competitiveness can translate into
macroeconomic imbalances, eventually leading to a painful adjustment. Spain's experience
during the crisis is instructive in this regard.
With the start of Monetary Union, the disappearance of exchange rate risk premia and the
unprecedented fall in interest rates facilitated capital inflows and encouraged risk-taking
behaviour, resulting in a rapid rise in private debt and a property boom. The expectation of higher
levels of income led to excessive consumption and investment relative to the supply capacity of
the Spanish economy. This continuous demand pressure generated a positive inflation
differential vis-à-vis the rest of the euro area, leading to a strong appreciation of the real
4
exchange rate and an erosion of price competitiveness.
When the crisis hit, the subsequent adjustment was severe - with unemployment rising above
25 percent, a rapid erosion of the fiscal position and a number of bank failures - leading to a
significant contraction in both domestic demand (see Figure 3) and real GDP. The same was
true for other current account deficit countries, such as Portugal, Ireland and Greece.
For countries with large current account deficits, the adjustment was painful. The correction of
euro area macroeconomic imbalances was particularly asymmetric, with the bulk of the
adjustment falling on current account deficit countries through a strong contraction in domestic
demand, with limited support from a higher demand contribution from current account surplus
countries, despite those countries being less affected by the crisis. Growth in the surplus
countries, including Germany, became even more export-oriented (see Figure 4).
An important lesson from the crisis was that the euro area had insufficient tools at its disposal to,
on the one hand, prevent the build-up of unsustainable asset price booms and, on the other
hand, mitigate their impact if they do occur. The answer to such problems lies, ex ante, in better
macroprudential and microprudential policies and better regulation of the financial system and, ex
post, in better resolution institutions. Strengthening Europe's financial framework, including the
establishment of the banking union, is the right way to address this source of macroeconomic
imbalances. It is of the utmost importance to complete the banking union without delay.

Competitiveness problems in the euro area can also be attributed to factors other than the
financial cycle, such as the lack of adequate wage and price flexibility or impediments to factor
mobility. The importance of such economic factors already featured prominently in the theory of
optimal currency areas, as pioneered by Mundell in 1961. Competitiveness imbalances are one
of the most visible symptoms of insufficient macroeconomic adjustment mechanisms in the euro
5
area. The developments in Germany and France - two countries which together represent
nearly half of euro area GDP, and have seen broadly similar movements in GDP and in prices
(see Figures 5 and 6) since the start of Monetary Union - are instructive in this regard.

Germany, at the start of Monetary Union, was considered the "sick man of Europe". At the time,
the country was still recovering from the high costs associated with its reunification and its
6
conversion rate was widely considered to be overvalued. The national policy response was a
7
prolonged period of union-backed wage moderation together with a significant labour market
overhaul which aimed, among other things, at improving job search efficiency and employment
8
flexibility. The result was striking: from 1999 to 2008, nominal unit labour costs were virtually
unchanged for the economy as a whole (see Chart 8) and were thus growing significantly below
9
what the "golden wage rule" would suggest. This resulted in a strong export performance, but
weak domestic demand. The economic policies Germany pursued before the crisis largely
explain why it emerged relatively unscathed from the Great Recession. Exports recovered swiftly
and currently stand at an all-time high, roughly equalling half of the country's GDP. Exports
recovered particularly strongly towards non euro area countries. As a result, the decline in the
euro area share in total German exports accelerated. Meanwhile, the domestic demand
contribution to GDP continued on its downward path, in part on account of subdued wage growth
together with a tight fiscal policy (see Figure 12).

In contrast to Germany, France entered Monetary Union in much better shape. Growth in the
initial years was strong and unemployment declined by more than a fourth within five
10
years. Wage increases remained moderate, even below euro area averages (see Chart 7),
and unit labour costs moved according to the "golden wage rule", i.e. at an average annual rate
below, but close to, 2%. However, with German unit labour costs remaining virtually unchanged
over the period, a significant competitiveness gap built up. This was further aggravated by the
crisis, during which French wages remained relatively sticky, in spite of the sharp fall in
11
productivity. The consequences were especially detrimental for the French export sector, which
suffered significant losses in market share (see Figure 9), despite the substantial squeeze in
profit margins (see Figure 10). At the same time, the contribution of domestic demand to growth
became increasingly important, supported by fiscal policy (see Figure 11) and sticky wage
developments.

As a result, there is now a striking divergence between France and Germany on a number of
macroeconomic dimensions: in Germany, the domestic demand to GDP ratio is now among the
lowest across advanced economies, whereas in France, it is among the highest. The opposite is
true for exports (see Charts 13 and 14).

The recent economic policy orientations and plans set out by the German and French authorities
are steps in the right direction. In particular, the labour market reforms that have already been
implemented by the French authorities, and those that are still planned, could yield sizeable
growth benefits and improve competitiveness. These recent developments show that
crosscountry interdependencies in the Monetary Union are better internalised in national
decisionmaking processes.
Some lessons for the future
Our monetary policy measures are bearing fruit, and the growth outlook confirms our confidence
that inflation will converge towards our aim of below, but close to, 2% over the medium term.
Monetary policy alone cannot prevent divergences in a monetary union. Sound economic policies
are the key drivers of Europe's prosperity. They are pivotal to the smooth functioning of EMU,
thereby preventing the emergence of macroeconomic imbalances.
The nature of EMU makes macroeconomic adjustment in the euro area more complex than in a
federal state. Monetary policy is a competence assigned at EU level. The European Central
12
Bank's price stability objective is enshrined in the Treaty. By contrast, economic policy remains
13
in the remit of Member States. It is, however, a Treaty obligation for Member States to regard
their economic policies as a matter of common concern and to coordinate them.
Our framework for the coordination of economic policies was clearly not effective in preventing
the emergence of lasting imbalances in the euro area in the run-up to the crisis. Protracted
losses of competitiveness eventually led to unsustainable external positions and even "sudden
stops" in the financing of external deficits. This is not new. Unfortunately, we can point to several
episodes in history when governments and social partners failed to internalise external
constraints, resulting in widening imbalances. This typically led to currency crises and exchange
rate realignments in Europe. Monetary instability prevented Europeans from reaping the full
benefit of the internal market and limited Europe's growth potential and emergence as a global
economic actor.
In our institutional framework for economic policies, it is primarily up to the Member States to
respond to the economic challenges they are faced with, thereby ensuring that their economic
structures are compatible with participation in Monetary Union. To reap the full benefit of
Monetary Union, it is essential to ensure that national economic policies lead to sustainable
growth. Preventing the emergence of economic imbalances and creating the conditions for a
thriving social market economy is not only a matter of national interest. It is also a matter of
common concern, as a crisis in one country has repercussions for all members of Monetary
Union. Effective surveillance is needed at both EU and national level.
Looking ahead, we need to further enhance the coordination of national economic policies.
National economic policies, the effects of which can propagate through the EU, should no longer
be decided in isolation. At the European level, the European Semester process for the
coordination of economic policies - including the macroeconomic imbalance procedure - which
14
was introduced by the EU in 2011, can play a key role. However, it should be used to its full
potential. Equally important, though, is for national debates and decision-making processes to
more fully internalise what it means to be part of Monetary Union. Precisely for this purpose, the
15
Five Presidents' Report of 12 February 2015 called for the set-up of National Competitiveness
16
Authorities. These bodies are intended to foster national responsibility for identifying any
necessary reforms and facilitating their implementation. Subsequently, the Council of the
European Union adopted on 19 September 2016 a Recommendation for the establishment of
17
National Productivity Boards and Member States were invited to implement the
Recommendation by 20 March 2018. We should make full use of this Recommendation. National
Productivity Boards have the potential to become an important catalyst in supporting the sound
functioning of national adjustment mechanisms.

The "two-pack" and "six-pack" legislative packages, which bundle together 6 regulations and 1 directive, aim to
more closely coordinate economic policies through (i) a strengthening of budgetary surveillance under the
Stability and Growth Pact, (ii) the introduction of a new procedure in the area of macroeconomic imbalances, (iii)
the establishment of a framework for dealing with countries experiencing difficulties with financial stability and
(iv) the codification in legislation of integrated economic and budgetary surveillance in the form of the European
Semester (see, for instance, eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A52014DC0905 ).

The golden wage rule states that real wages should grow in line with (medium-run) national productivity and
nominal wages so as to be compatible with price stability. This implies that nominal wages in each country
should equal (medium-run) national productivity plus the target inflation rate of the central bank (see, for
instance, European Commission, 2005). In practice, this would mean that on average, unit labour costs growth
should approximately equal the target inflation rate of the central bank.

To reinforce ex ante coordination of EU Member States' economic and fiscal policies, a new monitoring cycle
was introduced in 2011: the "European semester" - a six-month period every year during which national
budgetary and structural policies will be reviewed to detect any inconsistences and emerging imbalances while
major budgetary decisions are still under preparation. Specifically, the reform reinforces the preventive arm of
the Stability and Growth Pact, introduces a new procedure for addressing macroeconomic imbalances, and
places greater emphasis on monitoring the national fiscal frameworks, identifying macrostructural growth
bottlenecks and detecting macrofinancial risks in the Member States (see W. Köhler-Töglhofer and P. Part
(2011), Macro Coordination under the European Semester. Monetary Policy and the Economy December 2011
