I copy here the BoE's forecast, source: ONS
We are heading for growth between 2.3% +/- 2%.
Where is the cliff edge that you are so worried about?
Your lack of objectivity is evident.
Tell me why do you imagine this "Growth" will occur, when the only thing keeping the so call "Brexit Boom" going is the fact that consumers are spending money as if it is going out of fashion?
And where are we going to sell goods that we don't currently make, using Trade Deals we haven't got yet, to?
And that is assuming (Which we can't) that the Financial Swindles worked from London will continue without suffering any setbacks?
You are looking at an Extremely "Best Case Scenario" so while you are at it, why not factor in a sudden Discovery of Gold or Uranium in the old Cornish mines , or do these so optimistic Projections already have assumed that?
Here is an alternative view not sponsored by the Leave Campaign
FT verdict
With clear and easily specified economic risks in the short and medium- term, Brexit does not easily pass any cost-benefit analysis.
Michael Saunders, an economist at Citigroup, anticipates a series of three big shocks: “Worse export performance due to inferior EU access for business and financial services; lower potential growth and lower consumer spending from reduced migration inflows; and weaker investment growth, reflecting the above factors plus extra uncertainty.” This would hit the government budget, requiring higher taxes or lower public spending amid higher costs of financing the deficit, he adds.
Remind me, who's level of objectivity is suspect?
