Richard Posner does an excellent job of describing the economic mess were in, and why traditional measures of economic stimulus likely won't work. More importantly though, he examines the Obama program--asking the important questions.
There are three basic questions to ask about the program. The first is whether it is necessary, the second whether it has the right structure, and the third whether it is the right size.
His answer to the first question doesn't really give my any comfort though.
Ben Bernanke, the chairman of the Federal Reserve Board and the leading economic student of the Great Depression of the 1930s, is a conservative economist. Conservatives don't like huge deficit-spending programs, or at least the public-works and transfer-payment components of them, which increase government involvement in and control over the economy. Bernanke supports the program, after having failed to avert a depression by means of monetary policy alone. Almost the entire economics profession converted--virtually overnight--from being Milton Friedman monetarists (Friedman believed that only bad monetary policy could turn a recession into a depression) to being John Maynard Keynes deficit spenders.
Yeah, that much is obvious, but in rhetorical terms, this isn't an argument, its an appeal to authority--smart guys think this is the right way to go. The irony here is that Posner is one of these smart guys, and he's relying on the other smart guys to provide his own comfort on the question.
I am not happy.
On the other hand, he does offer opinions on why he favors some proposals and disfavors others.
Programs to transfer wealth are very difficult to abolish, because interest groups form about them. The problem is somewhat less serious with public-works programs, especially road-building and other infrastructure projects, and especially those infrastructure projects that were planned or begun by states or municipalities and interrupted or deferred because of the fall in tax revenues resulting from the depression. The federal government can finance these projects until the depression is over, and then the states can continue them with its own tax money.
Posner's explanation of why he opposes wealth transfer is a bit cryptic, but essentially his criticism is that its inflationary. It moves the economy from a diversified structure, to a far more simpler one, directly more money to fewer suppliers. It would be as if we had wallets full of cash, and all the grocery store had to sell was Clamato juice, and not enough of it--the price would eventually become ridiculous.
Everybody likes the infrastructure idea, but there are many problems with it as well. Major projects take years to plan and license, and there is no indication of how many ready-to-go infrastructure projects there are available to stimulate economic activity. Its also a fact of life that building roads, bridges, etc... is hugely energy intensive. We can expect the demand for oil to spike seriously, even as Pelosi and her merry band of idiots attempt to close ANWR permanently to energy development.
Posner suggests that doing it "well" might not matter, because its the fact that somebody is spending money that counts, but he doesn't sound convinced.
Properly structured, a Keynesian program can help to check a downward economic spiral. With monetary policy apparently inadequate to avert a downward spiral big enough to trigger deflation, there may be no good alternative to such a program.
That sounds suspiciously like, "Do you have a better idea?"
In my view, it sounds like all the big economic brains are seriously out of their depth, and hedging their bets by opting into a consensus--there is protection in the herd. Ironically, this is precisely what got us into trouble in Iraq--listening to a bunch of herd animals in the officer corps. Bush tapped Petraeus, Roosevelt tapped Eisenhower--neither a herd animal, and both men ultimately the right choices to deal with ambiguous circumstances.
Obama has neither the education or experience to understand the economy and even be remotely capable of recognizing a truly good idea. In fairness, McCain wouldn't have been any better. It seems to me that we need a brainstorm outside of the halls of Congress if we have any hope of avoiding another Great Depression.
