7A good question, no simple answer
- Should curreny area borders coincide with
national borders? - If not, how best to delineate currency areas?
- What economic criteria should be used?
8 The economic toolkit
- There must be benefits and costs involved
in adopting a common currency - The solution has to involve trading off
these benefits
9In a nutshell
- The benefits
- Money exhibits increasing returns to scale
(network externalities) - E.g. you save transaction costs for money
exchange the people use your currency - The world is the way to maximize these benefits
- The costs
- Loss of monetary and exchange rate instruments
- Matters in presence of
- Price and wage stickiness
- Asymmetric shocks
10Focusing on costs
- Start with the idea that benefits argue for one
worldwide currency - Ask why not
- Look at the costs
- No precise way of estimating costs and benefits
so, in the end, a matter of judgement - Look at asymmetric costs
- How they create trouble
- What makes them more likely
- What makes them less painful
11Asymmetric shocks
- Simplest example an adverse demand shock
how can the exchange rate help? - Assumption sticky prices and wages
- Definition of exchange rate
- EP/P
- or in terms of wages
- E W/W
12Asymmetric shocks
- Simplest example an adverse demand shock
how can the exchange rate help?
If domestic prices and wages are sticky, adverse
demand shock will reduce production to C if
exchange rate does not adjust
13Asymmetric shocks
- Simplest example an adverse demand shock
how can the exchange rate help?
If exchange rate adjusts, production declines to
D.
14Asymmetric shocks adverse demand shock in 2
country CU
15Asymmetric shocks adverse demand shock in 2
country CU
No currency union caseReal exchange rate
declines in country A to ?1, production declines
to B, country B remains unaffected. What would
happen if exchange rate stays at ?0?
16Asymmetric shocks adverse demand shock in 2
country CU
No currency union caseReal exchange rate
declines in country A to ?1, production declines
to B, country B remains unaffected. What would
happen if exchange rate stays at ?0?
17Asymmetric shocks adverse demand shock in 2
country CU
Currency union caseCentral Bank let currency
decline to ?2. production declines in country A
to C, in country B to D, and excess demand
creates inflationary pressure D-D.
18Asymmetric shocks adverse demand shock in 2
country CU
Disequilbria dont last forever. In country A
wages and prices decline, such that production
moves to equilibrium point B. In country B wages
and prices will increase, until economy is back
to point A as well.
19Implications of asymmetric shocks
- Thus, both countries are hurt when they share
the same currency - Also the case when a symmetric shock creates
asymmetric effects - This is an unavoidable cost of a currency area
20Six critieria for a optimal currency area
- Next questions
- What reduces the incidence of asymmetric shocks?
- What makes it easier to cope with shocks when
they occur - The analysis develops six criteria for an
optimal currency area (OCA) - Three economic
- labour mobility
- diversion
- trade openness
- Three political
- transfers
- homogeneous preferences
- Common destiny
21Criterion 1 (Mundell) Labour mobility
- In an OCA labour moves easily across national
borders. - Caveats
- Labour mobility is easy within national borders
(culture, language, legislation, welfare, etc),
but much less so across national borders - Capital mobility difference between financial
and physical capital - In case of country specialization, skills also
matter and hinder labour mobility
22Asymmetric shocks adverse demand shock in 2
country CU
- What happens with labour mobility?
- Assume exchange rate declines to ?2 and
production is at B in country 1 and D in country
2.
23Asymmetric shocks adverse demand shock in 2
country CU
- Labour mobility shifts supply curve leftwards in
country 1 to S and rightswards in country 2 to
S. - New equilbrium ar C and D.
- Output gap is zero.
24Criterion 2 (Kenen) Production diversification
- Countries whose production and exports are widely
diversified and of similar structure form an OCA.
- Indeed, in that case, there are few asymmetric
shocks and each of them is likely to be of small
concern
25Criterion 3 (McKinnon) Openness
- Countries which are very open to trade and trade
heavily with each other form an OCA. - Distinguish between traded and non-traded goods
- Traded good prices are set worldwide
- A small economy is price-taker, so the exchange
rate does not affect competitiveness - In the limit, if all goods are traded, domestic
good prices must be flexible and the exchange
rate does not matter for competitiveness
26Criterion 4 Fiscal transfers
- Countries that agree to compensate each other for
adverse shock form an OCA. - Transfers can act as an insurance that mitigates
the costs of an asymmetric shock - Transfers exist within national borders
- Implicitly through the welfare system (e.g.
unemployment benefits) - Explicitly in federal states
27Criterion 5 Homogeneous preferences
- Countries that share a wide consensus on the way
to deal with shocks form an OCA. - Matters primarily for symmetric shocks
- Prevalent when the Kenen criterion is satisfied
- Do countries agree how to adress symmetric
shocks? Should we favour exporters (currency
depreciation) or consumers (currency
appreciation)? How much? - May also help for asymmetric shocks
- Better understanding of partners actions
- Encourages transfers
28Criterion 6 Commonality of destiny
- Countries that view themselves as sharing a
common destiny better accept the costs of
operating an OCA. - A common currency will always face occasional
asymmetric shocks that result in temporary
conflicts of interests - This calls for accepting such economic costs in
the name of a higher purpose - Solidarity vs. Nationalism
29Is Europe an OCA?
- A synthetic OCA index
- How much of a currency appreciation/devaluation
vis-à-vis the DM is needed to keep economic
conditions unchanged? - A ten year period is considered.
- Indicator for the relevance of adjustment
pressures from asymmetric shocks.
30Inside the OCA index Openness
- Most EU countries are very open The McKinnon
criterion is broadly satisfied
31Inside the OCA index Diversification
- Most EU countries have a diversified production
structure (intra-industry trade dominates) - The Kenen criterion is broadly satisfied and well
explains which countries joined the euro area
32Inside the OCA index Labour mobility (1)
- The labour mobility criterion cannot be
black-and-white - The migration response to economic incentives
must consider many costs - Moving costs
- Risk of becoming unemployed
- Longer run career opportunities
- Family prospects
- Eligibility to welfare
- Taxation
- Cultural/linguistic differences
- National attachment
33Inside the OCA index Labour mobility (2)
- An international comparison suggests that labour
mobility is low in Europe - Across countries
- Even within countries
34Inside the OCA index Labour mobility (3)
- Low labour mobility implies that unemployment
bears much of the burden of adjustment to shocks - An US-EU comparison
- How much of an initial employment shock is
absorbed by labour mobility?
35Inside the OCA index Transfers
- The EU does not satisfy the transfer criterion
- The overall EU budget
- is low, capped at 1.27 of EU GDP
- entirely used for administration, CAP, regional
and structural funds - These funds do not vary with the business cycle
and are not earmarked to address asymmetric
shocks - This changes with the ESM/ESRM facilities in the
course of the Eurocrisis
36Inside the OCA index Homogeneity of preferences
- Preferences could affect the role of monetary and
fiscal policies to address external shocks - Little is known about this criterion
- Eurbarometer survey suggest that people agree on
common decisionmaking for defence (64), but 67
reject decisionmaking in the area of social
affairs - Eurocrisis show increasing tensions across
nations and their populations and disagreement
e.g. on fiscal transfers and macroeconomic
policies
37Inside the OCA index Commonality of destiny
- Little is known about this criterion
- Public opinion polls did not reveal deep
opposition to EU institutions when EURO was
introduced - But support faded away in course of the EURO
crisis - Differences between the South and North of
Europe, particularly between the crisis countries
and Germany - Criticism of the Troika
38Summarizing
Criterion Satisfied?
Labour mobility No
Trade openness Yes
Product Diversification Yes
Fiscal transfers No (but tend to increase)
Homogeneity of preferences Partly (eroding?)
Commonality of destiny ?
39Overall
- Is the OCA glass half full or half empty?
40History never ends the endogeneity of OCA
criteria
- Living in a monetary union may help fulfill the
OCA criteria over time - Would the US be an OCA without a single common
currency? - Will the existence of the EURO area change
matters too ? - Will the Eurocrisis create further integration
e.g. via fiscal transfers and common fiscal
policies or further disintegration? Split between
the South and the North? - Will no-Eurozone members leave EU, e.g. UK?
41Will trade deepen?
- Little evidence that reducing exchange rate
volatiliy increases trade - Mounting evidence that eliminating exchange
rate volatility by adopting a common
currency raises trade a lot - Estimates range from 50 to 100
- The border effect provides similar estimates
42Will diversification grow or decline?
- Argument 1 intra-industry trade will grow
- Argument 2 specialization will increase
- No firm conclusion so far
43EMU and labour markets
- Mobility may not change much, but wages could
become less sticky - Two views
- The virtuous circle labour markets respond to
enhanced competition by becoming more flexible - The hardening view labour markets respond to
enhanced competition by increasing protective
measures that raise stickiness - The jury is still out EURO crisis has not much
increased labour mobility in 2010, but in 1st
half year of 2013 - E.g. Greek migration in Germany 80.
- But Substantial diversion of migration flows
from NMS equilibriate labour supply between
crisis and non-crisis countries
44Are the other criteria endogenous?
- Transfers
- No support for more taxes fo finance transfers at
beginning of EMU - But Meanwhile 50 of German population support
at least some transfers to bailout Greece - Homogeneity of preferences
- No presumption that it will change soon, but EURO
crisis my force countries to do so (e.g. zero
debt ceiling) - Commonality of destiny
- No presumption that it will change soon, but EURO
crisis my lead to contradicting forces
45In the end
- Monetary union is not only about economics
- The OCA criteria do not send a clear signal
- The EU is not a perfect OCA
- A monetary union may function, at cost
- The OCA criteria tell us only partly where the
costs will arise - Labour markets and unemployment
- Political tensions in presence of deep asymmetric
shocks - Fiscal shocks and imbalances like real estate
bubble remain largely unadressed
46Fiscal Policy and the Stability Pact
- Fiscal Policy and the Stability Pact
- Fiscal policy in the monetary union
- More and more important?
- Borrowing instead of transfers
- Automatic stabilizers and discretionary policy
actions - Fiscal policy externalities
- Spillovers and coordination
- Cyclical income spillovers
- Borrowing cost spillovers
- Excessive deficit and the no-bailout clause
- Collective discipline
47The fiscal policy instrument
- In a monetary union, the fiscal instrument
assumes greater importance - The only macroeconomic policy instrument left at
the national level - Its effectiveness is increased (a result from the
Mundell-Fleming model) - Heavily used in 2008 financial crisis and
subsequent period - A subsitute to transfers
- Yet, many questions arise regarding its
effectiveness and use
48Limits on effectiveness
- The crucial role of private expectations
- A deficit today but a debt tomorrow who will
pay? - A tax cut, but how permanent?
- Slow implementation
- Agreement within government
- Agreement within parliament
- Spending carried out by bureaucracy
- Taxes not retroactive
- Result countercyclical moves can become
procyclical actions and in extreme cases create
fiscal crisis (default of government bonds)
49A crucial distinction automatic vs. discretionary
- Automatic stabilizers
- Tax receipts decline when the economy slows down,
and conversely - Welfare spending rise when the economy slows
down, and conversely - No decision, no lag nicely countercyclical
- Rule of thumb deficit worsen by 0.5 of GDP when
GDP growth declines by 1
50Public debt and automatic stabilizers in Europe
51A crucial distinction automatic vs.
discretionary
- Discretionary actions a voluntary decision to
change tax rates or spending - Technically a change in the structural budget
balance - But no automatic correction of deficits, so a
problem of discipline
52Should instrument be subject to some form of
collective control?
- Yes, if national fiscal policies are a source of
several externalities - (Positive) income externalities via trade
- Important and strengthened by monetary union
- A case for some coordination
- Borrowing cost externalities
- One common interest rate
- But EURO area integrated in world financial
markets - Sovereign debt default risk put other EMU
members or ECB under bail-out pressure
53Income spillovers, 1972 -2005
54What is the problem with the deficit bias?
- The track record is not really good (2005
2013)

Berechnungen.
55What is the problem with the deficit bias?
- The track record is not really good (2005
2013)
- Quelle OECD STAT Database, 2013 eigene
Berechnungen.
56What is the problem with the deficit bias?
- Fiscal indiscipline in parts of the EURO area
might concern financial markets and - Raise borrowing costs for all countries
unlikely, markets can distinguish among
countries - More serious is the risk of sovereign debt
default in one member country - capital outflows and a weak EURO
- pressure on other governments to help out
- pressure on the Eurosystem (European Central
Bank) to help out
57The answer to default risk the no bailout clause
- The no-bailout clause
- Overdraft facilities or any other type of credit
facility with the ECB or with the central banks
of the Member States (hereinafter referred to as
national central banks) in favour of Community
institutions or bodies, central governments,
regional, local or other public authorities,
other bodies governed by public law, or public
undertakings of Member States shall be
prohibited, as shall the purchase directly from
them by the ECB or national central banks of debt
instruments. (Art. 101)
58The answer to default risk the no bailout clause
- The no-bailout clause Question of credibility
- Ex post the world looks different See the
Draghi-statement of the ECB on debt default - Thus, fears remain
- Informal pressure
- Impact on EURO
- Prevention is better, especially given a
tradition of indiscipline
59In the end, should fiscal policy independence be
limited?
- The arguments for
- Serious externalities
- A bad track record, anyway
- The arguments against
- The only remaining macroeconomic instrument
- National governments know better the home scene
60The general principles
- Two general arguments for collective action
- Externalities
- Increasing returns
- Two general arguments against collective action
- Heterogeneity of preferences
- Information asymmetries
- And a caveat
- Governments may pursue own interests
61How to restrain fiscal policies?
- Distinction No.1
- Micro/structural aspects (tax and spending levels
and structure) - Macro aspects (the balance between tax revenues
and spending) - Distinction No.2
- Coordination voluntary and flexible efforts at
taking into account each others action - Binding commitments or rules
62The Stability and Growth Pact
- Formally, the implementation of the Excessive
Deficit Procedure (EDP) mandated by the
Maastricht Treaty - The EDP aims at preventing a relapse into fiscal
indiscipline following entry in euro area - The EDP makes permanent the 3 deficit and 60
debt ceilings and foresees fines - The Pact codifies and formalizes the EDP
63How the Pact works
- Emphasis on the 3 deficit ceiling
- Recognition that the budget balance worsens with
recessions - Exceptional circumstances when GDP falls by 2 or
more automatic suspension of the EDP - When GDP falls by more than 0.75, country may
apply for suspension - Precise procedure that goes from warnings to
fining
64The procedure
- When the 3 ceiling is not respected
- The Commission submits a report to ECOFIN
- ECOFIN decides whether the deficit is excessive
- If so, ECOFIN issues recommendations with an
associated deadline - The country must then take corrective action
- Failure to do so and return the deficit below 3
triggers a recommendation by the Commission - ECOFIN decides whether to impose a fine
- The whole procedure takes about two years
65The fine schedule
- The fine starts at 0.2 of GDP and rises by 0.1
for each 1 of excess deficit
66How is the fine levied
- The sum is retained from payments from the EU to
the country (CAP, Structural and Cohesion Funds) - The fine is imposed every year when the deficit
exceeds 3 - The fine is initially considered as a deposit
- If the deficit is corrected within two years, the
deposit is returned - If it is not corrected within two years, the
deposit is considered as a fine
67The Broad Economic Policy Guidelines (BEPG)
- Emphasis on precautionary measures to avoid
warnings and fines - The stability programmes are embedded in the
wider BEPG, a peer-monitoring process that
includes the Lisbon strategy - Each year, each country presents its planned
budget for the next three years, along with its
growth assumptions - The Commission evaluates whether the submission
is compatible with the Pact
68Issues raised by the Pact (1)
- The BEPG shift the focus to ex ante commitments
- Led to the Irish warning (2001)
- Decisions are taken by the ECOFIN, a political
grouping - France and Germany treated leniently in 2003-4
- Imposition of a fine can trigger deep resentment
- Are fines credible?
- If not, what is left?
69Issues raised by the Pact (2)
- Does the Pact impose procyclical fiscal policies?
- Budgets deteriorate during economic slowdowns
- Reducing the deficit in a slowdown may further
deepen the slowdown - A fine both worsens the deficit and has a
procyclical effect - The solution a budget close to balance or in
surplus in normal years
70Issues raised by the Pact (3)
- What room left for fiscal policy?
- If budget in balance in normal years, plenty of
room left for automatic stabilizers
71Issues raised by the Pact (3)
- What room left for fiscal policy?
- If budget in balance in normal years, plenty of
room left for automatic stabilizers
72Issues raised by the Pact (3)
- What room left for fiscal policy?
- If budget in balance or surplus in normal years,
plenty of room left for automatic stabilizers - Some limited room left for discretion action
- In practice, the Pact encourages
- Aiming at surpluses
- Giving up discretionary policy
- At first glance, the early years seems to be
hardest - Takes time to bring budgets to surplus
- Today we know, it is even harder after a shock
73The early years (before slowdown)
74Further controversies
- Discipline imposed from outside
- A further erosion of sovereignty?
- Arbitrary limits
- Why 3?
- What about the debt celing of 60?
- Asymmetry
- The Pact binds in bad years only
- A budget forever close to balance or in surplus
would drive debt/GDP ratio to 0
