The biggest argument against infrastructure spending as a stimulus is simply that you can not get the money into play fast enough for it to make a difference. These days, infrastructure building is a S-L-O-W process. Even the projects that are already approved and could be started immediately still have to be put out to tender - a process that typically takes months. Then once a company wins the bid it has to finish up projects it is currently doing and transfer resources to the new job. And this is assuming that all the up-front analysis, requirements, approvals, environmental studies, and other regulatory and engineering tasks have been met.
I’ve been looking for estimates on this, and it seems to me that there’s no way reasonable infrastructure projects could consume more than 200 billion within 12 months, and even that is pushing things. And many of these projects could take years to complete.
And with an accelerated approval process and an accelerated bid/tender process, any bets that these projects will eventually come in grossly over budget and over time? And that there won’t be enough oversight to prevent fraud and abuse?
But there are many, many other problems with trying to stimulate the economy with infrastructure. One is that you wind up with a more inefficient infrastructure afterwards, because the focus was on speed of implementation and political power rather than on what really needs to be done. This happened to Japan with its massive infrastructure ‘stimulus’ (which did not fix their recession, btw).
Yet another problem is the distortionary effect such a large injection of work will have on the economy. You’re not going to be able to staff all these projects from the ranks of the unemployed, because the kinds of people who need to do these jobs in any given area could easily be in short supply. You might have 15% unemployment in a geographic region and still not be able to come up with the number of mechanical insulators or certified steelworkers needed to do the job. And if you try to hire non-union workers for such jobs, I’m sure the Steelworkers of America and other unions will scream bloody murder.
Then there’s the Davis-Bacon act, which requires that all public works projects pay ‘prevailing’ wages, which generally means union wages. You’re not going to hire these workers for minimum wage, which means these jobs are going to be particularly expensive. Instead of putting one million workers to work at minimum wage, you’ll be putting 200,000 to work at $20/hr.
This act also means that the public works projects will often be the best-paying jobs in a region, which could easily have the result of pulling experienced workers from existing jobs where they are productive and enticing them into public works jobs. Then when the job is over, these workers will have no place to go, because the companies they used to work for will have either hired replacements or have gone out of business.
The majority of people who have lost their jobs are not $20/hr workers, but lower-paid service workers without the kinds of skills needed for these projects. Are you going to put unskilled workers into skilled trades and double their salaries in the process, in the name of a ‘stimulus’?
Injecting a trillion dollars worth of new work into the economy will change capital flows, reward some businesses and hurt others, cause shortages of materials and subsequent price spikes, etc (what will the price of steel and concrete do with a huge influx of construction jobs into the market?)
A ‘stimulus’ like this reminds of attempts to ‘manage’ ecosystems by injecting new predators or controlling populations in an attempt to be smarter than nature. It almost always has unintended consequences. It’s the height of hubris for a few hundred people in Washington to think they can push around a 20 trillion dollar economy and tweak and tune it with injections of capital. They don’t have the foggiest notion of what they are doing or what the unintended consequences of their monkeying will be.
If you want to stimulate the economy, you’d be better off just cutting business and payroll taxes (as Obama seems to be moving more towards), and letting the market sort out what to do. That, plus selected infrastructure spending for projects that are already set to go and were going to be started anyway in the next year or two is all that should be done.
