Scotland Bill

The hon. Gentleman is presenting the Laffer curve argument. He suggests that a corporation tax cut could pay for itself. As he knows, I support that idea and am looking at what the Government are doing in that connection. It is not altogether surprising that there are advantages in reducing corporation tax, but, initially at the very least, it comes at a cost. We had to put that in the Red Book. Does he believe that there would be no cost, or does he believe that the tax cuts would immediately pay for themselves?
