Bank of England forecasts 'improved'
The Bank of England has made "big improvements" in its ability to forecast the UK economy, the Bank's chief economist has told MPs.
Andy Haldane made his comment to the Treasury select committee.
He acknowledged that "sizeable" economic forecasting errors had been made in the past, especially at the time of the 2008 financial crisis.
He also said more forecasting errors were likely or possible, though not on the same scale as before.
Mr Haldane was being questioned along with other Bank officials, including governor Mark Carney, about their most recent inflation forecast, which substantially upgraded the Bank's forecast for the UK's economic growth this year.
In response to opening comments from committee chairman Andrew Tyrie, Mr Haldane acknowledged that some of the factors leading to the financial crisis had been predictable in advance, such as the rise of borrowing in the banking system, which he said was clear for all to see.
"We have seen financial crisis in the past and their seeds are often sown in leverage, and in that sense, some of the lessons of history had been forgotten to some degree," Mr Haldane said.
"[This was] by, not just parts of the central bank community but across the policy community, across academia and elsewhere."
Big improvements in forecasting had now been made, Mr Haldane asserted.
But one of Mr Haldane's colleagues, Gertjan Vlieghe, who is a member of the Bank's Monetary Policy Committee (MPC), tempered that reassurance in response to other questions from the MPs.
"We are not going to forecast the next financial crisis, we are not going to forecast the next economic recession," he said.
"Our models are just not that good," he added.
The Bank officials were challenged by John Mann, who accused them of looking at the wrong things and therefore misunderstanding how the UK economy was functioning.
He cited the ability of employers to draw in large numbers of low-paid workers from abroad, and he accused the Bank of overlooking the effect of the decline in home ownership during the past decade.
But Mr Haldane said that some recent mistakes in the Bank's forecasts, such as misjudging the immediate economic effect of last year's Brexit vote, were not on anything like the same scale as the mistakes made in the lead-up to the financial crisis nearly a decade ago.
