Immigration in the News

Immigration may be the only real issue that gets any progress during the next two years. Here are some things happening at the state level.
Georgia seeks to keep immigrants' kids out of higher ed, while California seeks to give them a path to citizenship through education or public service (The Economist) I would say a reasonable compromise might be to let them be admitted, but charge full tuition.
SB1070 aftermath in Arizona. When neo-Nazis are among your most vocal supporters, it might be a sign that you're not doing the right thing, even if half of all Arizonans are on your side.

Some links: Robot soldiers, wine allergies, and junk.

Arnold Kling thinks liberals are hypocrites for teaching their kids to work hard; would the corrolary be true (conservatives are hyocrites for teaching their kids to share and be nice)?
Using AI to data mine on the battlefield and optimize decision making. Proceed with caution.
Wine allergen found.
Do hands on my junk make me more safe? Probably not, but I don't care enough to complain (and certainly not enough to hassle a guy getting paid 15 bucks an hour.
Bruce Schneier, a security guru, calls all this “security theatre”. He suspects they merely prompt attackers to change targets, and reckons it makes more sense to invest in better intelligence.

Von Missing the Point

I am not an expert on the Austrian school of thought, but I have been reading a great deal more about it lately. I think that it has some interesting insights, but I find a recent piece in the Economist to be completely off-point in its attempt to give positive press to the school. Buttonwood writes:
A one-paragraph explanation of the Austrian theory of business cycles would run as follows. Interest rates are held at too low a level, creating a credit boom. Low financing costs persuade entrepreneurs to fund too many projects. Capital is misallocated into wasteful areas. When the bust comes the economy is stuck with the burden of excess capacity, which then takes years to clear up.

This is reasonably accurate. Unfortunately, this explanation is not terribly unique to the Austrian school. The Keynesian school proposed that there could be a credit boom (although they were less apt to blame the government for the fact that interest rates were too low). In fact, in a bit more precise way of looking at it, uncertainty and adaptive expectations (what Mr. Keynes called "animal spirits") play a more prominent role in the boom and bust cycle in the Keynesian model. It turns out that this is also true of the Austrian school. In fact, both schools attribute some of the fluctuation in the business cycle to a "coordination problem" in the processing of information revealed by noisy market signals.
OK, so where are they different? Well, basically on the matter of policy response. There is some evidence that keynesian deficit spending can help. There is other evidence that shows that a more austere approach is better. As in all things it is probably simply the case that the devil is in the details. Government spending is probably most helpful when it is invested in things that would be useful to have anyway (like roads, bridges, and energy infrastructure), and not simply money transfers that just substitute for other spending now or in the future (like transfers to states, tax cuts, or entitlement spending).
