I have a couple of questions. In his opening statement, Professor McMahon spoke about fiscal gimmickry, non-core expenditure and the way in which it is presented. He made the point that much of the spending is likely to be long lasting and, therefore, should be calculated in core expenditure. What is Professor McMahon's definition of long lasting?
