One of the
difficulties faced by the authors of the Government Expenditure and Revenues
Wales study (GERW) was that information on many items of expenditure and
revenue was not available separately for Wales, so they had to make estimates. And any estimate will always be based on one
or more assumptions. There’s nothing at
all wrong with that; it’s the only way of producing even an outline idea of
Wales’ position. The problem arises in
deciding which assumptions to make; different people would make different
assumptions – and I suspect that the same people might make different
assumptions as well, if the context were different.
That question
of context is one of the reasons why a study aimed at analysing Wales’ position
in the past (2014/2015) within
the UK will never produce the same answers as a study aimed at considering
Wales’ position in the future
as an independent nation. GERW was
clearly aimed at doing the former not the latter, and it seems to me that the
assumptions made are reasonable in that context, and that the document
therefore helps a great deal to aid understanding in that context.
If we were to
attempt to look to the future rather than the past, even within the context of
the continuation of the union, we would need to make a range of additional
assumptions about future policies and their impact on revenues and
expenditures, and we would also need to change some of the existing assumptions
on apportionment of revenue and expenditure.
I won’t cover all of those, but it’s worth considering a few just to
give a flavour of the differences which would emerge.
Firstly, what
would be the position in relation to the national debt? What would Wales’ share be? At the time of the Scottish referendum, the
UK Treasury indicated at one stage that it would continue to be responsible for
the whole of the debt, even if Scotland became independent. That was more about reassuring the lenders
than about establishing a start position for negotiation; and the SNP’s
response (that Scotland would take a share) was similarly about establishing
and maintaining international credibility.
But on what
basis should we estimate Wales’ share of the debt? GERW uses a per capita basis, but there are
other approaches. Part of the reason for
the debt is current expenditure, so if Wales receives more in benefits should we
take a larger share? But part of it is
also about funding infrastructure projects, where Wales receives less money
than our fair share, so should our share of the debt be less than on a per
capita basis? And even after
establishing a base line (difficult enough in itself) at the point of
independence, if we want to project forward we need to make assumptions about
future budget deficits or surpluses, borrowing patterns and rates of interest. None of these factors is entirely straightforward
or uncontroversial.
Or take defence
spending. GERW uses a per capita basis –
entirely reasonable to estimate Wales’ share of current spending. But
the UK spends around 2% of GDP on defence – other countries spend less (Germany,
for instance, spends around 1.1%). What
would an independent Wales spend on defence?
And GERW draws a clear distinction between spending for Wales and
spending in Wales; much of the current spending on defence goes outside Wales,
which means that we pick up the cost in the GERW figures, but don’t get the
whole GVA benefit, or the multiplier effect.
In an independent Wales, whatever we spend on defence would be in Wales
as well as for Wales.
Or take pensions. How do we assign the costs of pensions? Wales has a higher proportion of pensioners
than the rest of the UK taken as a whole.
Part of the reason for that is that people choose to retire to
Wales. Who should pay their
pensions? In a unitary UK, the question
doesn’t arise, but in the scenario of an independent Wales, it most certainly
does. When citizens of the UK retire to
France or Spain for example, their pensions are paid by the state in which they
contributed when they were working, i.e. the UK. France and Spain do not pay those
pensions. So, in an independent Wales,
would Wales be expected to bear the cost, or would the arrangements be the same
as they are for any other member country of the EU? The latter seems likely, but even then there
is a further complication – does that apply to existing retirees or only to new
ones? The latter would seem to me to be
easier to implement and manage, but the historical commitment might well be a
factor which those negotiating a share of the national debt would wish to take
into account.
My purpose in
all the above is in no way to disparage the work of those who have produced
GERW; indeed, we should be grateful to them.
It is, rather, to give a flavour (there are many more points which could
be made) of why a study of Wales’ current position cannot simply be extrapolated without significant change to a
conclusion about the position of an independent Wales at some future date. And that's a project which will require a lot more work.
