I delivered these comments as part of a roundtable on the future of the euro at the University of Auckland, New Zealand, in October of 2012. Enjoy!
"First, thanks to Univ of Auckland for hosting this event and
in particular to Prof David Mayes and Mutsumi Kanazawa of the Europe Institute for
organizing the event.
The starting point for me is the economic theory behind
whether you should adopt a single currency or not. As any student of international economics
will know, Nobel Prize-winning economist, Robert Mundell, formulated the
conditions under which it would be advantageous for a country or member state
to join a single currency area. This is
known as the optimal currency area theory, and essentially says that your
business cycle has to be synchronized with that of the other members of the
group, or have some prospect of becoming synchronized, for it to be
advantageous to join.
Mundell specified that you could also have some offsetting features
that would then mitigate any lack of synchronization with the single currency,
namely a high degree of labor mobility or supranational fiscal transfers. Note that Europe has neither of these
offsetting features.
So in 1991 when the Maastricht Treaty passed, it contained legal
criteria for joining the euro, which had clearly been put in place by
politicians and their civil servants, as at the time it was widely criticized
by economists for being inappropriate.
The criteria were i) keep budget deficits below 3% of GDP; ii) keep
public debt below 60% of GDP, including falling towards that level from higher
levels; iii) keep long term interest rates within 2% of the average of the
lowest 3 in the EU; iv) keep inflation rates within 1.5% of the average of the
lowest 3 in the EU; and v) stay within the ERM for at least 2 years beforehand.
As you can see these criteria have little in common with
Mundell’s simple idea of an optimal currency area, and indeed, not only were
the Maastricht criteria misguided, but they also allowed too many EU member
states that were not suited to a single currency into the euro area, Greece and
Portugal being the prime examples.
To give you an analogy, it’s a bit like saying you’re going
to start a bowling club, and although you know that the best members,
regardless of their weight, ethnic background, height or hair color, will be
those that are interested in bowling, you decide that membership should depend
on being over a certain weight, under a certain height, long arms, and
preferably black or blonde hair, simply because you might have watched
professional bowling and seen that the players tend to have these
characteristics, and therefore at the time of membership application these were
the features you thought to look for. This is precisely analogous to what
happened with the euro area. Those that were let in had to satisfy certain
criteria at a certain point in time which had very little to do with whether
the member state would be an appropriate member of a single currency.
Now there is also an extension to the OCA theory called the
Endogenous OCA approach – it says that because monetary unions usually occur on
top of common markets ( - think most federal or confederal states), then using
the euro might stimulate more flows of factors of production between the member
states, making them more economically integrated with one another which might then
lead their business cycles to move more closely together. In other words, before the fact or ex-ante, a
member state might not look as though it’s eligible to be a member, but once it
becomes a member or ex-post, it’s economic dynamics might change so that it
would be selected as a member under the OCA approach.
So moving back to our analogy with the bowling club, if you
let members in who were not very good at bowling but were committed to regular
attendance and keen to get stuck in and to socialize and ask other more
experienced and better players for advice, they could become good bowlers after
a time. Of course if you used the
analogous method to the Maastricht criteria, in other words selecting members
according to certain specific features, you would hope that the members you let
in would grow longer arms, become shorter and weigh more, and change their hair
color. Oops, maybe my analogy breaks
down a little here!
Given that we have this membership problem right at the
outset, even before the economic downturn at the end of the last decade, some
stresses and strains within the euro area were already apparent. This is particularly because member states
had to continue to limit their budget deficits under the Stability and Growth
pact, but obviously when the major downturn occurred the OCA theory really
began to highlight the membership problem.
What I’m really trying to say here is that economics truly
matters. Just like you can’t build a
house without obeying some principles of construction ( - unless you like to
witness disasters), you can’t build a monetary union without having some
preconditions and those preconditions are very neatly laid out in Mundell’s
optimal currency area theory. Ignore
them at your peril!

Now when you look at the euro area through this lens, and
I’ll be doing exactly this at my research seminar tomorrow, you’ll realize that
as there is very limited labour mobility in the EU, and currently little
prospect of a federal political system being introduced in Europe, then having
synchronized business cycles is key to remaining part of the euro area. My research shows that certain member states,
although they might have been hitting the headlines recently for their economic
problems, are much more easily going to be able to stay in the euro area than
other troubled member states. Member
states like Spain and Italy, for example, even though they have deep-seated economic
problems, have growth patterns that are quite similar to other euro area member
states, while member states like Greece and Portugal do not have such similar
patterns of growth, and therefore do not fit well, in good times or bad. Some
member states like Finland seem to conform to the endogenous OCA view, as
Finland started off not fitting too well, but over time it’s growth dynamic now
appears to be much more in line with that of the rest of the EU.
So what should happen to resolve and therefore end the euro
crisis? My opinion is unashamedly
research based, which is where I think we economists need to hang our hats if
we are to have any credibility, particularly given our lack of foresight in
other areas of major concern where we failed to take warnings seriously and do
proper research to be able to make useful policy recommendations.
So, in my humble opinion, either one of two things needs to
happen. Either:
1 – we move towards a more federalist structure in the EU,
with permanent mechanisms in place for fiscal transfers. Canada has them set up as a formal policy
structure (the “equalization payments”) and the US has them on an informal
basis ( - through the US budget). Either
would work, but that is the only way that if we stay with the current members
that we’ll see this situation resolved in the long term; or
2 – the member states that do not form part of an OCA, and
given that they’ve been members for over 5 years already, show little sign of
becoming part of one in the future, need to be told to leave. As an economist, I don’t care what means are
used to get member states like Greece out of the euro – bribe them if necessary
– but they need to leave, and leave fast before the situation there spirals out
of control and the EU has more than just an economic crisis on it’s hands.
In my opinion the most dangerous path is that the Greeks
decide to try and stay, despite the fact that their economy is in meltdown
mode, and the austerity packages continue to fail because the economy is
shrinking and so tax revenue is falling while at the same time public
expenditures and wages are having to be savagely cut, hence reinforcing the
downward spiral. The costs of leaving
might be large, but the given that I cannot see any way for things to get
better right now, this is the only way to put some light back in the tunnel, so
to speak.
On the EU side, the danger of neither of the options
occurring is probably greater than the danger of one of the corrective actions
I have recommended. Why is that? Because if nothing is done, then internal
indebtedness inside the EU must increase as lending to certain member states
has to be maintained for them to remain members. So if the Europeans decide to be polite – then
no one is going to ask you to leave given that you want to stay, so the only
way to stop contagion to other member states is to keep changing your bailout rules
and mounting new lending programs, as we lurch from one emergency to the next.
As Willem Buiter, who incidentally was one of my Professors
at Bristol when I was there, recently said in the FT – if this continues much
longer you might start to see Germany, Finland, Austria and others start to make
noises about leaving the euro themselves, as despite the advantages of being
members right now, if things continue too far down the road of trying to keep
the current membership at the expense of the clear OCA members ( - the “hard
core” if you like), then the disadvantages of being members may start to
outweigh the advantages. So the scales
might then tilt so that it might appear to be the best course of action for
these natural OCA euro members to leave.
So, now to put my political economy hat on, there are 2
remaining questions: of the options I have outlined, which a) would be
preferable in an ideal world and why; and b) is going to be more palatable from
a political point of view.
I think that from the perspective of European integration, a
more federalist structure is preferable, as it then means that the OCA problem
nicely goes away and no one gets booted out of the club. Even Merkel has referred to this as being the
best long term solution. The big
downside is that It likely means that Europe will splinter, as a federalist
type EU governance structure is not something that the UK or many Central and
East European member states ( - such as Poland) want. But the EU cannot be all
things to everyone, and at some point the EU will have to accept this, and move
into a world of what I think of as a permanent state of so-called “variable
geometry”.
The upside to the second option, that of asking member
states to leave (either directly by telling them to go, or indirectly by
refusing to make any further concessions or mount bailouts), is that once done,
you don’t have to worry about the euro area being an OCA either, because you
lose the member states that were the problem in the first place, leaving the
rest of the members to get on with it.
But the downside is really not good.
It means that there will be considerable resentment and bitterness in
Greece, Cyprus and perhaps Portugal, if they end up leaving too. It also means that the EU’s vision of a
single currency for the whole of Europe can be essentially written off. Of
course with this option you don’t have to consider further integration –
essentially you move backwards and recognize that a monetary union without
further integration is only viable with certain member states involved.
The most difficult aspect of this whole thing lies in the
response to the last question I want to ask today: which of these options is
going to be more palatable from a political standpoint? The honest truth is that neither solution is
palatable to the EU at the present time.
I think it will take another crisis of some sort to get them to act, and
in the meantime the “hard core” of the EU will start making life more difficult
for Greece et al so that it hopefully decides to leave on it’s own accord. That would open the door for others to
follow.
So to end with, I see a much bigger danger here if the
current trend of the “hard core” making life more difficult for the likes of
Greece, Spain and Portugal continues, and that is that member states start to
act on the basis not of the good of the whole (i.e. the EU), but in terms of
what they themselves want. This will obviously
lead to much less compromise in the EU and will make it much harder to get agreements
in other policy areas, as member states are more likely to be unwilling to
compromise if they feel that they’ve been bullied or not dealt with fairly when
it comes to their involvement in the single currency.
Let’s hope we don’t go down that path.
Thank you for your kind attention."
