All right. Your comment here.... Let me take one, then: infrastructure, about productivity. You refer to a recent study on the effect of infrastructure on productivity of Canadian business, which concluded that about one-quarter to one-half of business sector productivity growth over the last four years was attributable to infrastructure capital.
Am I to take it then that you have the ability to look at a model from previous occasions, determine its effect on productivity, but you cannot make a nexus, a connection between investments by governments towards job creation? That doesn't exist? How do economists then forecast what impacts there will be, if Statistics Canada can't give that information?
