The revised second-quarter GDP numbers are here -- and again dismal. What to do? "Janet Yellen is calling for investment in public infrastructure ... monetary policy tools have reached their limit .."
But here is a more plausible view: The Perils of Public Capital. Read the whole thing. It cites the many bridges to nowhere and other similar missteps. Are all of these failures invisible to Yellen and Summers -- and the many others of their persuasion?
The blinders seem to come on when the old-time religion, more public spending, is evoked. One can excuse the pandering and posturing Clinton and Trump, but the smart people are another story.
Here are two thoughts. First, for many academics, their intellectual capital is their whole being. Hold on to it at all costs. If nearly $1 trillion of spending on "shovel-ready" projects did nothing, suggest to spend even more. The model says so. Second, and related, many smart people have a strong need for closure. Ambiguity and open-endedness are no fun. The theory has to work.
So why all this sidewalk psychiatry? Because it is bizarre that our best and brightest will say anything on behalf of good old-fashioned public spending. And convenient for you-know-who.
Econ 101 says that capital markets are essential so that scarce resources not go into mal-investments. But we are in the unfortunate situation where public infrastructure and mal-investment have become almost synonymous.
