Dr. Kieran McQuinn:

One always looks at targets in terms of this or that level of investment in the economy or capital expenditure and what ratio one should have. In doing so, one is guided by international comparisons. However, it is more a case of looking at investment generally and seeing whether it is adding to the productive capacity of the economy. Overall, however, it is not a case of identifying a target and stating one must reach it. It is more a case of individually appraising different projects and seeing whether they make a contribution to growth.
