The Bank of England has make restitution for “big improvements” in its ability to forecast the UK economy, the Bank’s chief economist has divulged MPs.
Andy Haldane made his comment to the Treasury Select Committee.
He admitted that “sizeable” economic forecasting errors had been made in the before, especially at the time of the 2008 financial crisis.
He also said numerous forecasting errors were likely or possible, though not on the same prorate increase as before.
Mr Haldane was being questioned along with other Bank officials, containing governor Mark Carney, about their most recent inflation vaticination, which substantially upgraded the Bank’s forecast for the UK’s economic growth this year.
In his opening questions, the committee chairman Andrew Tyrie, beseeched Mr Haldane about his recent speech, in which he had said that prognosis errors leading up to the financial crisis had been a “Michael Fish” tick for the entire economics profession.
Mr Haldane acknowledged that some of the components leading to the financial crisis had been predictable in advance, such as the wax of borrowing in the banking system, which he said was clear for all to see.
“We have perceived financial crises in the past and their seeds are often sown in leverage, and in that feel, some of the lessons of history had been forgotten to some degree,” Mr Haldane bid.
“[This was] by, not just parts of the central bank community but across the design community, across academia and elsewhere.
“That was a big error,” he admitted.
Big advances in forecasting had now been made, Mr Haldane asserted.
But one of Mr Haldane’s colleagues, Gertjan Vlieghe, who is a fellow of the Bank’s Monetary Policy Committee (MPC), tempered that reassurance in return to other questions from the MPs.
“We are not going to forecast the next financial danger, we are not going to forecast the next economic recession,” he said.
“Our models are reasonable not that good,” he added.
The Bank officials were confronted by John Mann, who accused them of looking at the wrong things and accordingly misunderstanding consumer behaviour and how the UK economy was functioning.
He cited the ability of companies to draw in large numbers of low-paid workers from abroad, and he accused the Bank of permitting the effect of the decline in home ownership during the past decade.
“This is something almost which we will have to pay particular attention in the coming years if there’s, as is to be look for, some adjustment to the nature, scale, magnitude of inward migration to this boondocks,” Bank governor Mark Carney responded.
But Mr Haldane said that some up to date mistakes in the Bank’s forecasts, such as misjudging the immediate economic begin of last year’s Brexit vote, were not on anything like the done scale as the mistakes made in the run-up to the financial crisis nearly a decade ago.
“I as a matter of fact was drawing a distinction between our learning from the time of the global economic crisis – which was a big one, massive error, to which we and others have then be affected – and the events over the last six to 12 months where the error was on nothing equal to the scale.
“Quite a lot of what we have learned is basically new news, numbering policy changes.”
Addressing the issue of inflation, which is the Bank’s biggest responsibility, Mr Carney said he expected the fall in the value of sterling since the Brexit show of hands to push inflation higher for some time, potentially until 2020.
“One of the schools we learnt from the depreciation of 2007-08 is that exchange rate pass-through is entirely protracted,” he said.
The Bank’s most recent inflation report prognosis that inflation, as measured by the consumer price index, would be at 2.4% in three years’ notwithstanding – above the Bank’s 2% inflation target.
