If an independent Scotland chose to follow the Republic of Ireland’s low-tax route, as SNP leader Alex Salmond has indicated it would, Scotland’s growth rate might be expected, over a five-year period, to move closer to Ireland’s trend growth rate of 7 percent. Given a further five years of Scottish growth at that trend level, and before diminishing returns set in, Scotland’s growth over the ten-year period would put its index 71.5 higher, more than a two-thirds increase in GDP.

By contrast, says Stein, the rest of the UK would be expected to have grown rather less, by just over a quarter. The result would be dramatic for Scotland. Measured in household income per head, Scotland, which started £1,700 behind the rest of the UK, could be expected to be £6,000 ahead of it at the end of that period.
