The document summarizes a presentation on the relationship between competitiveness and external capital flows in EU countries. It discusses the Euro Plus Pact, which assumes that weak competitiveness, as measured by increasing unit labor costs, leads to current account deficits. However, the presentation finds that empirical evidence does not support this relationship. Granger causality tests and VAR models instead indicate that increased capital inflows lead to a short-term real exchange rate appreciation and deterioration of competitiveness. The findings suggest the Euro Plus Pact has the causal relationship backwards and that relative wages are highly dependent on credit availability.

4. Main “idea” of the Euro Plus Pact
Crisis countries are crisis countries because of weak competitiveness!
The (relative) unit labour costs of GIP(S) countries Greece, Ireland, Portugal
and Spain have increased: this is the fundamental cause of their problems as
export performance must have been bad, pushing them into current account
deficits.
Gros (2011, p. 1):
Competitiveness ↓ (e.g. Unit Labour Cost = ULC ↑)
⇒
“Deterioration” of Current Account balance, CA ↓
Financial vulnerability ↑
⇒
Crisis if financial shock
[Empirical proof a la Commission ]

Is the implied / assumed direction of causality of the Euro Plus Pact correct?
▫ Time-based identification of direction of causality… ☺
Linkage(s) between capital flows and competitiveness important in itself

Original name Pact of competitiveness
German / Commission suggestion in late 2010 not enough to impose constraints
on fiscal policy – competitiveness to ensure financial stability
Next name Pact for the euro
German-French compromise
Final name Euro Plus Pact
Goals
Competitiveness
Employment
Public finances
Financial stability
(Tax policy coordination)
Implementation and “enforcement” “Open Method of Coordination”

10. Main focus
Competitiveness measured using developments in Unit Labour Cost = ULC
Policies in Euro Plus Pact to improve competitiveness
▫ Abolish wage indexation
▫ Reform wage bargaining
▫ Public wages ↓
▫ Deregulate industries
▫ Infrastructure ↑
▫ Education ↑
Here
Does improved competitiveness reduce financial imbalances?
▫ Does relative ULC ↓ ⇒ current account ↑?

11. 3. Briefly on the literature
Discussion of Euro Plus Pact
Mostly from spring and summer 2011
Gros & Alcidi, Gros (Eurointelligence), Schiliro, Wyplosz
How to measure competitiveness?
▫ Why not start ULC index series in 1992?
▫ ULC ↑ if more attractive product
Adjustment by deficit countries vs. adjustment by surplus countries
Urgent crisis, but slow-working instruments

12. Linkages between capital flows and competitiveness
Competitiveness ↓ ⇒ current account balance ↓
Theory trade sensitivities
Real exchange rate appreciation / ULC ↑ / competitiveness ↓ ⇒ NX ↓ ⇒ current
account ↓

Theory the transfer effect
Capital inflow ⇒ demand for non-traded products ↑ ⇒ wages etc. ↑ ⇒ unit labour
costs ↑ / real exchange rate appreciation [ “demand story”]

▫ Dutch disease foreign exchange earnings ↑ ⇒ real exchange rate appreciation

14. Conclusion from literature
Theory both directions possible
Gaps in literature
Few / no papers examines underlying logic of Euro Plus Pact
Few / no papers examining current account balance and competitiveness in the EU
Few (one?) papers examining causality in both directions
NB: No explicit theory is tested “descriptive statistics”

15. 4. Data
Panel
27 EU countries
Annual data 1995-2011
Notation
RULC = Relative Unit Labour Costs (in euro, relative to EA12 average)
▫ RULC ↑ ⇒ competitiveness ↓
GRULC = Growth in Relative change in Unit Labour Cost, %
▫ GRULC > 0 ⇒ competitiveness ↓
CA = Current Account balance, % of GDP
▫ CA < 0 negative current account balance capital inflow
DCA = Difference in Current Account balance, %-points of GDP
▫ DCA < 0 “deterioration” of current account balance capital inflow ↑

GRULC, DCA panel stationary in sample 1997-2011 ☺
CA borderline case [ use DCA in baseline regressions]

Questions
Does DCA Granger-cause GRULC? does lagged DCA help explain GRULC?
Does GRULC Granger-cause DCA? does lagged GRULC help explain DCA?
Estimations (1 year lag)
DCA = α0 + α1DCA(-1) + α2GRULC(-1) + εCA
GRULC = β0 + β1GRULC(-1) + β2DCA(-1) + εGRULC
GRULC ⇒ DCA if H0: α2 = 0 cannot be rejected

19. Panel estimations
Few observations along time dimension
“Average effect” across EU countries ☺
NB1: Few observations along time dimension 1 and 2 year lags
NB2: Most often country fixed effects
Clustered standard errors in ( )-brackets, p-values in [ ]-brackets
/12EPP-show9_EP.doc 19
22. Summary of results of Granger causality tests
No effect from GRULC(-1) to DCA
Effect from DCA(-1) to GRULC
▫ Sign “correct” DCA ↓ ⇒ GRULC ↑
▫ Magnitude reasonable (-0.4 to -0.6)
Robustness similar but slightly less “clear” results with CA

23. 6. VAR models
Advantages
Model dynamic linkages between endogenous variables
Allow contemporaneous effects
Panel Vector AutoRegressive models GRULC, DCA ~ I(0)
Results
Estimates from GRULC to DCA (violet) small and statistically insignificant
Estimates from DCA to GRULC (orange) larger (in numerical terms) and
statistically significant
Country fixed effects
/12EPP-show9_EP.doc 23
24. NB: Estimates like (2.4)-(3.4), (2.5)-(3.5) and (2.6)-(3.6), but standard errors not
clustered

29. Results
Competitiveness ↑ ⇒ capital inflow / current account 0
▫ At short-term “positive” effect, possible counter-intuitive effect in longer term
Capital inflow ↑ ⇒ competitiveness 2-3 year ↓ ☺
Robustness
Without country fixed effects

Sample shortening (not so strong for EA12…)
CA level (but results of CA ↑ on GRULC less clear…)

30. 7. Final comments
Summary
No / few signs of effect from competitiveness to current account balance
Effect from current account balance to competitiveness
▫ Increased capital inflow ⇒ real exchange rate appreciation in the short term
▫ Relative wages / competitiveness “very endogenous” variable dependent on
credit availability…
Lessons
Euro Plus Pact the cart in front of the horse?
Understand pattern in Estonia before crisis – and after crisis…
Important to understand causes and effects of capital flows – current account
balance matters also in a currency union!
Policy discussion
Possible to address “excessive” capital flows?
▫ Macro-prudential regulation
▫ Inflows and/or outflows. When excessive? Which policies?
