Office for Budget Responsibility, what is it good for? “Absolutely nothing”
seems to be the answer in Andrew Alexander’s column
for the Daily Mail
this morning. It surmises that George Osborne must
regret establishing this independent institution for fiscal forecasts as “so
far he is the only man it has bitten”. This is because the OBR’s predictions,
which Mr Osborne must operate within, have “proved consistently wrong … and,
worse, consistently in the wrong direction.”

much to agree with in all this. After all, the OBR’s forecasts—most
significantly, its growth forecasts—have often been undone by economic
realities. In the ‘pre-Budget
it delivered in June 2010, the organisation foresaw growth of 1.3
per cent, 2.6 per cent and 2.8 per cent in 2010, 2011 and 2012, respectively.
And the actual outcome? 1.8 per cent, 0.9 per cent and roughly zero. Given that
the forecasts for tax receipts and borrowing and debt are largely built from
these numbers, it’s rather a problem. As I said in a column
of my own
last year, we’ve had to learn a difficult lesson over the past
few years: that there are few fiscal certainties.

I still think Alexander is being a bit harsh here. For starters: if the OBR is
to be attacked for dodgy predictions, then it’s worth pointing out that almost
every forecasting body in town made—and has continued to make—similar errors.
Indeed, the Treasury produces a useful document
each month collecting the forecasts made by a range of independent organisations,
from Citigroup to the IMF. In May 2010, the average
growth forecasts made by these organisations were 1.1 per cent for 2010, 2.1
per cent for 2011, and 2.4 per cent for 2012. The OBR may have been slightly
more optimistic than that average, but not by much. ‘Most everyone was
underestimating the trauma to come.    

it’s not as though the Treasury had a great forecasting record itself, before
the OBR was established. As I like
to point out
: if you compare the actual amounts borrowed in the five years
to 2007 with the original forecasts made in Gordon Brown’s Budgets, New Labour
exceeded their expectations by over £100 billion — and that was during the good

not enough to defend the OBR by saying that others are just as bad – but,
happily, there’s a positive story to tell, too. Having an independent
forecaster attached to the Treasury is important for one particularly reason:
it diminishes the Chancellor’s—any Chancellor’s—capacity to use his political
power for ill. I mean, remember Gordon
Brown’s fiscal rules
? Until the financial crisis became too bad to pretend
any different, forecast horizons and borrowing projections were consistently
massaged just to make sure these rules weren’t broken. Debt was stuffed behind
HMT filing cabinets. It was a charade. Whereas now, if George Osborne is to
break his fiscal rules, the OBR will just say so – and already has. There’s
less smoke and fewer mirrors.

there are other joys afforded by the OBR, among them its annual “Fiscal
Sustainability report”
. Alexander dismisses this as a “waste of paper” –
yet while I’d agree (and have
) that there’s something weird about a report which tries to make
fiscal forecasts for fifty years hence, when The Jetsons is set, I wouldn’t say it’s a waste. What the OBR is
trying to do is point out the long-term strains on our public finances, the
effects of a growing and ageing population. That, in itself, is an important
public service.

any case, the OBR is here to stay – it would be politically toxic for any party
to deliver less transparency and less independence in how the public finances
are calculated, from now on. So while this forecasting body is biting George
Osborne at the moment, it’s going to bite other Chancellors in future. And, after
the excesses and deceptions of the Brown years, that ought to be a cause for
