Well, I think I agree with Professor Bartlett. It depends as well on the motivation for the spending. Again, if it were for fiscal stimulus—and here I tend to disagree with you, from a national perspective, about the need for fiscal stimulus—it's no longer there. Of course, we would like to have the benefits from the infrastructure sooner rather than later, but major projects, such as the ones you've maybe alluded to for reducing congestion in major cities, take a lot of time and planning. They often cannot be forced to meet some other timetable.
I think we need to think of these two types of infrastructure spending quite separately. As I indicated in my remarks, I'm quite negative about the notion that infrastructure spending is an appropriate use for fiscal stimulus.
