Why the Last Economic Stimulus Package Should Have Included Infrastructure Investments

Mark Thoma explains:

.... If we had included, say, infrastructure spending as part of the initial stimulus package, then the effects would kick in on a sustained basis over time rather than as a one-time hit as with the tax cuts. Thus, this type of spending could have provided the continuous stimulus Shiller is calling for. And if we are wrong and there is no recession, how big a problem is that? Well, what's so bad about building new infrastructure repairing what we already have, don't we need to do that anyway? With a stronger economy, wouldn't it be easier to pay for it? Insurance that also has investment value seems like a good bet to me. ....
