Dr. Eddie Casey:

There is huge uncertainty around those types of estimates, the ones the Central Bank would have used and that we use. Part of the reason is they tend to be average effects over the course of a full cycle, but when you are in a position like this when there has never been a jobs market this tight and we have never had employment rates this high, it is hard to really be that convinced that it could be of that order. It could be much larger again. The worry is the persistence of it, that once it is kept it higher, it gets on track, becomes deanchored and you see it for longer.
