Finance Bill

As I said, I think the Laffer curve is an interesting principle, but I prefer empirical curves and empirical results from experiments. We know from the ’80s that if the rate is cut, it increases the take. For me, the uncertainty is not about whether reducing the rate from 50p to 45p will cost the Exchequer £100 million, but about whether it will add £100 million or £200 million to the Exchequer as fewer people seek to avoid tax.
