Professor Edgar Morgenroth:

We can do with more of it. If we had more detail as to what we might want a united Ireland to look like, we could do more research on that and the effects of it, and try to optimise what might happen. We opened up with this. We set out scenarios for potential costs - values are completely different. We want to minimise those costs and maximise the benefits. That is what we should be doing, and I think doing more research will help us do that.
