please quote some IFS style sources from proper policy economists independent of party politics that say that abandoning the RUK tax payers funding of Scotland through the Barnett formula is a great idea for Scotland
No one has said it will be great for Scotland. Neutral-ish would be good. It's not about suddenly being a ridiculously rich country, it's about being to manage our finances ourselves to our own priorities. It is also worth noting that a future within in the UK is not looking particularly rosy either... Anyway according to this not-particularly-neutral source independence would not be an unmitigated disaster...
"An independent Scotland might have been able to negotiate a good deal on the share of the UK’s debt it took on. Lower debt would mean lower debt interest payments and would therefore reduce the budget deficit. However, it is worth noting that even if an independent Scotland had inherited none of the UK’s central government debt, its budget deficit would likely still be substantial: around 7.6% of national income (rather than 9.4%) in 2016-17 and 4.4% of national income (rather than 6.2%) in 2020-21 holding all other elements of our projections fixed.
Independence could affect Scottish economic performance. A weaker performance – which perhaps may be expected in the short term – would tend to push up Scotland’s deficit. But if, as the Scottish Government have previously claimed, independence would allow policies to grow the Scottish economy more quickly, such faster growth would tend to push up revenues and reduce Scotland’s deficit.
Independence would also, in principle, give the Scottish Government more freedom to tax and spend more or less, which could have implications for the Scottish budget deficit. In practice, however, if an independent Scotland faced a budget deficit anything like that in our projections, spending cuts or tax rises would be needed to put the public finances on a firmer footing"
