“Current account imbalances in the euro area:
competitiveness or demand shock?”
*The views expressed here are my own and should not necessarily be interpreted as those of the Banque de
France or the Eurosystem
2. Outline
• EA CA imbalances: facts and causes
• Building-up of imbalances (graphs)
• Rebalancing? (graphs)
• What to do?
• Structural reforms: the cost of non-
coordination

5. Competing narratives
• Negative competitiveness (supply) shock in
the South /North
• Excess demand in the South
• Financial shock: excess credit, real estate
bubbles, larger non-tradable sector…
• Deleveraging + Sudden Stop, lack of lender of
last resort… until “whatever it takes”
– De Grauwe: EA countries issue debt in a “foreign”
currency

6. My favorite narrative
• The crisis revealed growing divergence across EA
countries, where convergence was expected
• In a sense the euro worked as it promoted cross-
border flows of capital within the EA
• But this capital was misallocated: non-tradables
versus tradables (Kalantzis 2015 –more below),
• (Anticipated) spread convergence, and not “catching-
up”, caused EMU imbalances (Sienna 2016)
6
7. • Clear lack of macro-prudential supervision before the
crisis
• Asymmetric adjustment: CA adjustment supported by
deficit countries (capital account reversal) with little
adjustments in surplus countries
• Imbalances (NEP) are still there and need to be
addressed: too much savings in the Euro Area hamper
the recovery process
• Growing EA surplus (a drag on demand elsewhere)
• Relative price adjustments are still needed and this
requires cooperation

8. Who is responsible?
• Excess saving in the North (GE +NL, AT) had to
be balanced by excess investment in the South
(given a stable EA CA)
• Creditors (in GE, FR, etc.) failed to identify the
accumulation of credit risk linked to cross-
border lending activities
• Excess investment/borrowing in South or
excess saving/lending from North?
Low interest rates suggest excess lending
8
9. “South” is/was heterogeneous
• Spain: convergence, but only intensive (more
capital and labor, low productivity growth),
construction boom fuelled by inward funds
(through banking sector), private debt
• Greece: signs of convergence but clear excess
public spending
• Ireland: real estate boom, private debt
• Portugal: no convergence, no construction boom,
loss of EU structural funds and remittances

10. Kalantzis "Financial fragility in small open economies: firm
balance sheets and the sectoral structure" (2015), Review of
Economic Studies, 82 (3).
• Increase in financial openness
• larger capital in flows lead to a larger relative size
of the non-tradable sector.
• access to cheaper foreign loans leads firms to
increase their leverage
• Kalantzis (2015) shows how the evolution of
these two factors tends to make crises more
likely. N-to-T ratios and large credit-to-GDP ratios
are good predictors of twin crises (Sudden
stop+Banking crisis)

31. Cleansing effect of the crisis: demand shocks
• Within-sector reallocation across firms is more sizeable among European
countries with large current account adjustment.
• Explained by relative demand shocks faced by high and low productive firms in
home and foreign markets (Berthou, 2016)

stressed and non-stressed economies
Source: Bartelsman et al. (2015a), based on CompNet data (sample with 20+
employees). Notes: CompNet The non-stressed countries are Belgium, Germany, Finland and France, while the
stressed countries are Spain, Italy and Slovenia. Pre-crisis data cover the period 2004-08 (with the exception of Spain,
for which only 2008 data are available), while crisis period data cover the period 2009-12.

33. Net external debt crucial
• Luis Catão, Gian Maria Milesi-Ferretti 2013
• “Debt seems to be a lightning rod for crises
[…] the ratio of net foreign liabilities to GDP, and
in particular its net external debt component, is
indeed a significant crisis predictor”
33
36. Global perspective, at the ZLB
• EA surplus clearly not a solution
• In a global ZLB environment surplus countries hold
world output down (Caballero et al 2015:”Global imbalances
and currency wars at the ZLB”, Eggertsson et al 2016 “A contagious
malady? Open Economy dimensions of secular stagnation”)
• Coeuré 2015: “[…] help policymaking escape the
obsession of “competitiveness” which, when
narrowly defined, focuses on export market shares,
real exchange rates and unit labour costs. Such an
approach indeed risks perpetuating the fallacy of
composition where all economies aim to export low
demand”
36
37. What to do?
• EA NEP OK but (own) debt matters: EA debt must be
shifted away from deleveraging countries/agents to
countries/agents with better balance sheet, less
financially constrained
– Does not imply that investments should be made only in
GE: channel savings to where they can be best employed
(solar panels in GR?)
• Blanchard 2016: EA should engineer higher inflation
to allow Southern countries to reestablish
competitiveness and eventually recover
– Successful rebalancing through relative price adjustments
extremely difficult with low EA inflation (Berthou &
Gaulier 2013)
37
38. What to do?
• Coordination of economic policies
• Macroprudential policy, Banking supervision
• Fiscal and Competitiveness Councils
• Financing and Investment Union
• EA fiscal capacity
• Which tasks for a euro area Finance Minister?
(Villeroy de Galhau 2016)
– preparing the euro area-wide collective strategy
– supervising the implementation of policy objectives
and institutional discipline
– implementing centralized crisis management
38
39. Structural reforms: the cost of non
coordination (Gaulier 2016, France Stratégie)
• At the ZLB some structural reforms could be
detrimental to output (deflationary impact drives
up the real interest rate. See Eggertsson)
• Empirical results: null or negative impact of
(some) labor market reforms when macro is bad
(see , Duval et al 2015)
• But because of competitiveness gains unilateral
reform is still profitable
• Beggar-thy-neighbor structural reforms
implemented
• Classic prisoner dilemma: a negative sum game

Export/GDP (~Tradables share) strongly correlated with
ULC, both before and after the crisis

48. Pay attention to Gross flows
• “…current accounts deficits or surpluses,
linked to net capital flows, miss important
dimensions of the process of international
adjustment of countries and of their financial
fragility in crisis times. After all, the euro area
was running a balanced current account vis-a-
vis the US and yet it was deeply affected by
the US financial crisis of 2007-8.” (Gourinchas
& Rey 2013)
