Yesterday on the blog we ran a piece that highlighted, through the use of the sectoral balances approach, that the Scottish macroeconomy looks completely different depending on whether we include oil and gas revenues or not. If we include Scotland's geographical share of oil and gas Scotland is a very rich country indeed. If we do not they are quite poor.
In that blog post we mentioned that even if an independent Scotland does get access to their geographical share of the North Sea oil reserves there still may be substantial macroeconomic instability due to the instability of oil revenues. Some readers wondered just how volatile these revenues might be.
Below we have included a graph that shows Scottish oil and gas exports as a percentage of GDP, Scotland's net exports as a percentage of GDP and finally the Brent oil price. (All data on Scotland is taken from the Scottish government statistics database while the Brent oil price data is sourced from FRED).
As we can see, Scotland's trade balances is dominated by oil and gas exports. When the latter rise/fall so too does the former. We can also see that Scotland's trade balance is, for this reason, extremely sensitive to movements in the oil price.
We should also note something rather important about the measures. Since we have measured oil and gas exports against GDP and since GDP is generally growing, in order for oil and gas exports to continue to buttress Scotland's trade surplus they must continuously grow in lockstep with GDP growth.
This means that, in order for Scotland to maintain a persistent trade surplus, either the price or quantity of oil and gas sold abroad must increase sufficiently over time to keep pace with GDP growth.
The fact of the matter is, however, that the amount of oil and gas Scotland sells abroad does not grow continuously over time. In part this is reflective of the fact that in order to increase the supply of oil sold abroad Scotland must make new oil and gas discoveries, and in part this is reflective of the fluctuations in the oil price.
The following graph maps the percentage change in total oil and gas exports against the oil price. What we see is a high degree of sensitivity of oil and gas exports to the price of oil.
Particularly concerning is that as the oil price has stopped climbing in the last three years the year-on-year increase in oil and gas exports in Scotland has fallen and even gone into the negative. This suggests that in the past decade Scotland has been relying on rising oil and gas prices to ensure that their oil and gas exports grew at pace with GDP.
This provides strong evidence for what we wrote about yesterday: namely, that an independent Scotland needs an extremely flexible macroeconomic framework which can deal with such potential shocks. To this we would now add that they also require a long-term plan because, as oil and gas reserves dwindle and price increases peter out, Scotland will need to replace this source of exports with new industries that are attractive to foreign buyers.

A Tale of Two Countries: The Sectoral Balances of Scotland
When examining the Scottish economic statistics one thing immediately jumps out: namely, the dependence of just about every key macroeconomic variable on oil exports.
Without taking into account the geographic shares of oil and gas the Scottish economy comes across as extremely weak. But once we include the geographic share of oil the Scottish economy comes across as one of the strongest in Europe.
Yesterday the Scottish government released an experimental data series estimating the amount of oil and gas exports and imports coming out of and into the country. By combining this new dataset with other datasets that have been published -- namely, the quarterly national accounts and the estimates of public sector revenues -- we can form a relatively complete picture of the Scottish macroeconomy.
The best way to see the overall macroeconomy is through the lens of the sectoral balances approach as pioneered by the great British economists Lord Nicholas Kaldor and Wynne Godley. The sectoral balances show what each sector is contributing to the economy at large. It is a basic accounting identity that shows how one sector's surplus is another sector's deficit and vice versa (a more thorough breakdown of the framework can be found here while a less technical discussion can be found here).
The simple intuition lying behind the sectoral balances framework is that if one sector is net spending another sector is receiving income and net saving. This framework can tell us a lot about the structure of the macroeconomy. For example, prior to the 2008 financial crisis many countries had large private sector deficits. This led to instability in these economies as the debts accumulated by firms and households became too large.
Likewise, in the wake of the crisis many countries today have very large public sector deficits. These allow the private sector, by accounting identity, to net save, deleverage and draw down debt.
Here we will lay out two different sectoral balances for Scotland. One will show the sectoral balances for Scotland if the geographical oil and gas exports are included. The other will show the sectoral balances for Scotland if the geographical oil and gas exports are excluded. What we see when we examine these is two very different macroeconomic pictures. Here are the graphs.
The differences between these two charts is so striking that it is almost difficult to know where to begin.
As we can see, in the first chart -- the one which includes the geographic share of oil and gas exports -- we see a very robust economic picture. The private sector in Scotland is in a healthy position of large net savings -- implying very strong balance sheets and a low level of net private sector debt. Meanwhile the government does not have very large deficits -- an unusual situation in a world where, since 2008, public sector deficits of upwards of 8-10% have become the norm.
The reason for this healthy economic picture is the large amount of oil and gas exports. These ensure healthy trade surpluses which provide an inflow of income into the country and buttress Scottish saving.
When we take the geographic share of oil and gas out, however, we get a very different picture. In the second graph it is clear that Scotland is, apart from oil and gas, a country with a very large trade deficit -- this deficit is about twice the size of the otherwise large British and American trade deficits. In addition to this, when you remove the revenue generated from oil and gas the public sector also tends to run enormous deficits.
The net result is that private sector balances sheets look far more precarious. The private sector basically relies on enormous public sector deficits for its rather meager net saving position. It is easy to imagine how, if a Scottish government denied of its oil and gas revenues (which, by the way, are extremely volatile due to price and quantity fluctuations) ever tried to engage in austerity to reduce the size of its public sector deficits the economic contraction would be enormous.
We can also see from the above graph that if Scotland ever issued its own currency and did not have access to its geographic share of oil and gas the currency would likely collapse under the weight of enormous public sector deficits and trade deficits.
There are a lot of lessons contained in the above two charts and we have only begun to hint at them here. But the easiest takeaway from these graphs is that there are indeed two Scotlands. One Scotland, the Scotland with its geographic share of oil and gas, is rich and stable with high savings rates. The other Scotland, the Scotland with no oil and gas, is poor and would be prone to macroeconomic instability due to its large public sector deficits and trade deficits.
If Scotland does decide to shoot for independence come September of this year it had better have access to its geographic share of oil and gas. And even in such a circumstance the country will require a robust and flexible macroeconomic framework in place to ensure stability when volatility is inevitably encountered in the oil and gas market.
Update 14/02/2014: There have been some questions regarding just how Scotland's macroeconomy might respond to oil and gas fluctuations. In a post today we lay out the relevant statistics.

Note on sources: Despite enormous and valiant efforts on the part of the Scottish government and its statisticians, Scottish economic statistics are only in their most primitive phase. While the data seems so far robust it is presently only available for limited periods and for limited sectors. For this reason the above private sector balances are derived from the published trade and public sector statistics as they do not currently have an independent existence.

Carney’s Hedge
The media reaction to Bank
of England governor Mark Carney’s speech in Edinburgh this week has been rather
dramatic. Under the rather prosaic and dull title of The Economics of Currency
Unions, Carney’s talk – given the time, timing, place and audience – was
intended to be a ‘technocratic assessment’ of the pros and cons of the proposed currency
union that is integral to the SNP’s plans for an independent Scotland.
Rarely, I think, has a
lunch lecture to business dignitaries on such a topic set pulses racing. Yet
the London commentariat – despite their best efforts to hide their jubilation –
figuratively jumped for joy when the governor made his speech.
Of course, there has been a
lot of hedging of late on the issue of Scottish independence – not least as
most London-based national newspapers have relatively healthy circulations in
Scotland and are chary of losing 6 million potential customers. Usually there
is at least a pretence of impartial coverage. So it was interesting to see that
their reaction to this speech – detailing a cornerstone of prospective SNP
policy – nearly made them thrown caution to the wind and gloat over the central
banker’s intervention.
Of course, much of the
coverage fell along the usual predictable lines; most outlets decided this was
a disastrous intervention that boded incredibly badly for the Scottish
nationalist road-map. More measured analysts paint Carney’s approach as a calculated effort to remain above the fray. But what
precisely is Carney saying? Very few pundits
have attempted to paint this as positive endorsement of post-independent
Scotland’s monetary structures. Most have, instead, narrowed in on Carney’s
concluding remarks that ‘‘a durable, successful currency union requires some
ceding of national sovereignty’’. This is understandable, nor is it unusual to
surmise that Carney would not endorse any pro-independent policy.
Carney is, after all, a
political appointee and a deeply conventional economic thinker. When this fact
translates into his position on any given policy, it is typical to conclude
that his stance would be antipathetic to drastic alterations in the political
or economic structures of the United Kingdom. It is therefore unsurprising that
news outlets concluded that this was a ‘pounding’ of pro-independence
aspirations.
If this is an operating
assumption – and it is understandable to suppose so – then it might be worth
applying this presumption of Carney’s conservatism to the structure and
statements of his Edinburgh luncheon. That is, if our stating assumption is
that Carney attempted to put a damper on the independence blueprint, we should
look at how he went about it.
Firstly, the speech was
structured in particular way. Roughly, it was a speech of two parts that got
increasingly vague, incoherent and political toward the second half. After the
usual flattery and platitudes addressed to his Scottish audience (Scotland’s
great, thanks for the free lunch, Adam Smith etc.) Carney commenced with a
brief – very brief – description of the benefits of currency union. These
appear to be many, but were swiftly covered in the speech. Low transaction
costs, mitigation of foreign exchange risk, access to liquidity, the
maintenance of liquid markets, reduced borrowing costs (both personal and
sovereign), increased trade and easier mobility for labour and capital all flew
by in a few paragraphs. This was followed by the drawbacks of currency union in
relation to independent monetary policy.
The second half is more
interesting, but loaded with value-laden terms like ‘credibility’, ‘prudence’
and ‘stability’. There Carney indicated that a successful currency union would
have to maintain a central bank (the Bank of England) as a lender of the last
resort, a shared supervisory structure (the Prudential Regulatory Authority and
the Financial Conduct Authority) and a common financial deposit guarantee and
compensation structure (the Financial Services Compensation Scheme). It is
worth noting that this does not depart from SNP plans
for independence
– these will all be maintained, with only the Financial Ombudsman Service
becoming part of a ‘super’, all-inclusive consumer
dispute resolution service in Scotland.
So, this ‘banking union’ is
uncontroversial – it exists now and would continue to exist if the SNP had
their way. But Carney’s next point best illustrates his conservative position.
It is also indicative of the thinking that has sadly characterized economics in
the last few years. The lessons Mr Carney seemed to learn from the Eurozone
crisis seem firmly derived from the ‘peripheral irresponsibility’ school of thought. There
is not room here to point out how silly and flawed this argument is – but
applied to this debate, Carney indicated that fiscal policies in an independent
Scotland would have to be limited and monitored from London in case a departure
from ‘‘prudent behaviour’’ caused contagion in the wider currency zone.
Furthermore, a bizarre
argument based on moral hazard was put forward. Put bluntly, Carney stated that
a currency union would incentivize reckless spending by weaker countries –
because they were aware that they would be bailed out by the stronger country
that had ‘‘run their finances prudently in the first place.’’ That is, that
they would engage in reckless spending because the safety of the wider currency
union would be jeopardized if they were not bailed out from the effects of
their spending. The logical (in Carney’s argument) conclusion was an alleged
need for ‘‘tight fiscal rules’’ – namely, control of national budgets that
would render the intended results of Scottish independence negligible.
Obviously, this is both
insulting and intended to pander to an ingrained idea of Scottish
public-spending proclivity that is gaining increasing purchase in England. Let’s get it straight
however – Carney’s argument is that currency union (without ‘tight fiscal
rules’) would cause an independent Scottish government to spend too much due to
their awareness that Rump UK would ‘bail them out’ eventually. This is
nonsense. Does any government – or would any government – ever behave this way?
Of course not. Most bailouts have occurred due to unforeseen systemic shocks or
market shifts that reduce revenue, cause bank-runs or increase bond-yields.
They don’t occur because a government consciously overspends due to the
mercenary calculation that they will be ‘bailed-out’.
Of course, this is meat for
many opposed to Scottish independence. Yet there is something incredibly
encouraging from Carney’s intervention. Firstly, it was terribly mistaken, but
infinitely more measured than many other interventions (compared to, say, the
Treasury’s shrill prognostications and jeremiads). It is also possible that
Carney has no personal emotional investment in Scottish independence and was
attempting to edge debate toward considering a separate currency altogether. Carney
may also have been attempting a qualified endorsement of a currency union –
with the tacit caveat that it would be difficult to operate. For all that,
Carney did not hide his ideological stripes. He spoke as an austerian and
betrayed the incredibly unimaginative nature of his economic thought – one that
brought up the Euro-bogeyman frequently but doesn’t seem to have imbibed any
real lessons from the Eurozone crisis.
Mark Carney probably went
to Edinburgh intending to scupper the economic vision of the Scottish
nationalists. That his contribution was so weak and vague is heartening – after
disregarding much of the false assumptions and bad examples, a limited array of
modified financial instruments and decent policies could, and should, be able
to overcome the stifling limitations placed on Scottish economic policy before
and after independence. Failing that, let us hope, at least, that some sort of
imagination begins to be seen in tediously repetitive and acrimonious debate on
Scottish independence.

The Spanish Armada Sets Sail... For Scotland
The current debate on Scottish independence
– though far from quiet – has gotten louder as we approach the final
nine months before the referendum date of 18 September 2014.
These contributions are divisible into several noticeable
‘schools’ of commentary. First are the ‘hedgers’, who strive to be
inoffensive as possible. They generally have little of interest to say.
While much of the output has been informative, it is hard to avoid
noticing that diagnoses and predictions are indelibly
marked with the attitude of the organ or author – namely, it is easy to
tell when purportedly detached analyses is favourably disposed toward
independence or not.
Another strain of commentary tries to dismiss the debate as the latest in a series of long-running historical antipathies. These reductive accounts are generally hostile to independence and couched in terms that condescendingly view separatism as residual Anglophobic atavism - although, it must be admitted, the Scottish Government’s choice of the seven-hundredth anniversary of the Battle of Bannockburn for the referendum date does give that impression. Failing that, friction among the constituent peoples of the British Isles is presented as a timeless constant that may, or may not, be resolved without too much thought or action on the part of politicians, policy-makers and voters.

Failing that, friction among the constituent peoples of the British Isles is presented as a timeless constant that may, or may not, be resolved without too much thought or action on the part of politicians, policy-makers and voters.
Ireland is usually the ghost at the feast of this smorgasbord of commentary. Allusions are
made
– sometimes even whole
articles are devoted to the
sister isle. Of course, Ireland is incredibly important in this debate.
As the only state in existence that was once part of the union, it’s
political and economic travails over the past
century offer valuable lessons to British observers. The neglect of a
‘green’ angle to the debate has been lamentable, despite the recent,
very tardy integration of Irish lessons into considerations of this
issue over the past few months. But any meandering
beyond these narrow, archipelagal boundaries tend to be minimal. In
some respects his is a habit common to all political communities – that
of thinking that their problems are unique and do not extend beyond or
even exist outside their borders. The debate
remains firmly, even obsessively, focused on ‘British’ contexts,
replete with wild prognostications and ill-conceived pseudo-historical
pontifications.
Perhaps this constitutional conundrum is
better understood as the untimely coincidence of two specific contexts
that combine to promote already latent fissiparous tendencies, rather
than being solely a British issue. These two
contexts are the European context and the economic context – the
convergence of which has created the conditions for previously content
historic nations to attempt the separatist plunge. Essentially, this
originates in the combination of economic ideology
and political reality that has prevailed in Europe since the financial
crisis of 2008.
Regarding this political reality, the most
obvious contributing factor is the almost Byzantine levels of
continental, national, regional and local government that has become
Europe’s political structure over the past half-century.
From once unified nation-states, with strong local and civic
government, Europe has transmogrified into a trade-bloc, an incomplete
monetary union and a patch-work political entity. This state of affairs
mirrors the haphazard and disjointed evolution of Europe
over the past half-century. With free movements of labour, capital and
limited currency controls in a unified trade-bloc under the Schengen
Accord, there is little motivation for peripheral to remain within the
previous ‘nation-state’ unions they joined centuries
before.
The deleterious economic context refers to
the current ideological quagmire in the Euro and Sterling zones that
endorse obstinate and short-sighted austerity programmes. This adherence
is grounded in vaguely-defined economic theory,
but generally couched in terms of immediate personal morality; state
budgets are directly (and erroneously) approximated to household or
personal budgets. This has the understandable effect of scaring people –
but also promotes separatism in peripheries with
strong social democratic tendencies.
The political reality creates the
conditions that make separatism viable; the economic ideology causes
alienation in peripheral nations that makes separatism increasingly
likely.
Nothing illustrates the connection between
European and economic contexts better than Spanish Prime Minister
Mariano Rajoy’s recent
ham-fisted
intervention in the Scottish independence debate.
Why Rajoy, the Spanish Prime Minister,
should intervene so publicly in the domestic affairs of another EU state
might confuse an uninformed observer. It is even more surprising given
the Spanish government’s
posturing
over Gibraltar – posturing
which has seen them vigorously contest the right of British sovereignty
over the peninsula. So, did Rajoy’s intend to crow over the potential
dissolution of this one-time world power? On
the contrary, he intervened to weigh-in on the side of the British
government by warning that any future Scottish state could count on
Spain being as obstructive as possible when it came to EU membership.
The fact that the Spanish government raised
this as an issue shows some of the difficulties – even paradoxical
behaviour – caused by the growth of peripheral nationalism in Europe.
But the Spanish prime minister has indicated
that he will make it as difficult as possible to let Scotland into the
EU, not for any cohesive geo-political reason – Rajoy is doing so mainly
for domestic political reasons.
The current Spanish government is having a
difficult time. Due to their difficulty managing dissent in their
pursuit of Spanish austerity, they have (rather cynically) started
raising hackles about Gibraltar, willing to conscience
the possibility of isolating one part of the EU from another – against
the strict letter of European law and diplomatic convention.
They are also refusing to hold a debate on
Catalonia. Why the sudden urge for independence in Catalonia? Well,
Catalonia is a wealthy periphery, like Scotland, determined to maintain
their welfare state and standard of living
during a period of austerity from the centre of an established – and
quite old – multi-national state. In the case of both, such impulses are
coming from Madrid and London under the aegis of political parties that
have majorities in the ‘heartland’ of each
multi-national state; Castile on one hand and England on the other.
Both Catalonia and Scotland are, according to one commentator, ''middle
class enclaves in a more backward country - capitalist societies
struggling to be free, as it were.''
Thus, the current Spanish government has threatened to veto Scottish aspirations to EU membership in order to
scuttle
Catalonian ambition. And, while
goading Britain with smothered war over Gibraltar, hopes to comprise a
broad anti-separatist front with the UK in return for stifling these
same aspirations.
Obviously, their stance (as well as
austerity measures) have been the best endorsement possible for Catalan
nationalists. But by refusing to hold a referendum on independence they
are sowing trouble for the future - and they
may well reap a whirlwind. The same cocktail of peripheral nationalism,
class division, economic upheaval and conservative reaction led to the
Spanish Civil War. Officers of the Spanish armed forces have already
said they will intervene if
the
constitution is violated – a threat which, incidentally, went unreported in most media outlets.
Analysis
has, thus far, been somewhat narrow, focusing in separatist impulses
that supposedly inhere in sentiment, sense of self and ethno-linguistic
distinction. These, however, have always
been present. What, then, has compelled electorates in areas like
Scotland and Catalonia (and Val d’Aosta, Flanders, Lapland, Savoy, etc.)
to contemplate separate sovereign journeys? This is twofold – due to
the deleterious economic practices that lower standards
of living alongside the reality of multi-layered European sovereignty.
It is therefore, ideological and structural; or, in layman’s terms, it
is the EU and austerity.
The astute among you will have notice that the structural reality produces the economic pressure – but that is for another post. As it stands, if one of these conditions alter, nationalist votes might very well melt away like snow. It might be too late; differing political conditions have created different (and largely irreconcilable) political cultures.
