That is one of the reasons, of course, that some people say the public sector accounts for as much as 62% of employment in Northern Ireland. Some of it is disguised in the way the hon. Lady suggests.
We have to consider whether we can simply sit on our hands. However, there is a second consideration for the Northern Ireland Executive. Yes, there is some risk attached to the policy; all economic policies carry some risk, but in measuring and trying to balance that risk, we have to consider the impact of the policy elsewhere, especially in areas similar to Northern Ireland. I have already mentioned the approach of the Republic of Ireland Government.
As the changes to the rules on accounting and disclosure come forward, I know that some of the financial services issues might be addressed, but we have not touched on
the ongoing cost of the devolution of corporation tax, which is currently reckoned to be about £300 million. However, as the economy grows, a formula will be imposed in respect of the loss of revenue, and given that there could be a substantial reduction in corporation tax in Northern Ireland, the formula must not be draconian. For example, if it was set at an unrealistic rate, based on the performance of better performing regions or of the UK economy as a whole, the burden could become substantially higher as time goes on. We need clarity on that issue.
The right hon. Member for North Shropshire (Mr Paterson) said that from this day on the Executive should be proceeding with this matter, but we cannot do so because the Bill has not yet been passed. I know he is enthusiastic, but I think his enthusiasm has run away from the reality: the Bill has to pass its stages as normal.
