Mr. Brian Keegan:

It does occur to me that where one has high-value processes carried out by highly-skilled and highly-educated individuals, there is going to be a substantial difference between the productivity of Irish and other workers, if measured in terms of sales. There will also be a substantial difference if a big part of the value of those sales is derived from intellectual property wherever relevant. I accept the Deputy's point that he does not have any figures in front of him, but beyond those two general observations I do not know if I can comment sensibly any further.
