Fools and Gold

Krugman cites Keynes and Adam Smith on some modern money follies. Regulars will not be not find the theme surprising.

The third money pit is hypothetical. Back in 1936 the economist John Maynard Keynes argued that increased government spending was needed to restore full employment. But then, as now, there was strong political resistance to any such proposal. So Keynes whimsically suggested an alternative: have the government bury bottles full of cash in disused coal mines, and let the private sector spend its own money to dig the cash back up. It would be better, he agreed, to have the government build roads, ports and other useful things — but even perfectly useless spending would give the economy a much-needed boost.

Clever stuff — but Keynes wasn’t finished. He went on to point out that the real-life activity of gold mining was a lot like his thought experiment. Gold miners were, after all, going to great lengths to dig cash out of the ground, even though unlimited amounts of cash could be created at essentially no cost with the printing press. And no sooner was gold dug up than much of it was buried again, in places like the gold vault of the Federal Reserve Bank of New York, where hundreds of thousands of gold bars sit, doing nothing in particular.

Figuring out the other two money pits is left at the link - or as an exercise for the student.

Anti-Libertarian: re-post

The most pointed critique of social security and liberalism in general is the libertarian critique. The problem with libertarians, for a liberal, is that we have too much in common. We both believe in individual rights, tolerance of individual differences, and dislike government prescription of religion. The basic difference, it seems to me, is the different answers we give to Cain's (with thanks to the Captain - my original version had the corpse asking the question!) famous question: "Am I my brother's keeper?" That's not really my basic bitch against the libertarians though. My real complaint is the same as my complaint against most religion - its premise is a fraud. For those who can't stand to wait for the punchline, I believe that trying to implement libertarian principles leads to tyranny or social disintegration. Demonstrating that takes some historical (and pre-historical) context. For all but the last 15,000 or so of the 100,000 years the human spec

Uneasy Lies The Head

Uneasy lies the head that wears a crown ........... Shakespeare Henry IV, Part II. So it is with us and our slightly distant primate cousins , so it seems. A 9-year study of wild baboons in Kenya by Princeton University and the Institute of Primate Research may turn conventional assumptions of alphas males upside down. The study found that alpha males have high testosterone levels, which allows them to dominate other baboons, get access to more food, and attract better mates. This is expected. Surprisingly, though, the alpha males also have high levels of stress hormone glucocorticoid, which scientists measured from their feces samples. In fact, the stress of alpha baboons was on par with low-ranking baboons. The convention wisdom is that access to food and females provides life security and thus less stress for dominant males. Conversely, weak males who are constantly threatened by starvation and physical violence from stronger males are thought to be more stressed. The st

We Call it Soccer

The US played its best, and maybe only good game of World Cup, but lost thanks to brilliant goalkeeping by the Swedish keeper and the bizarre method soccer uses to settle ties when three US stars could not put the ball on frame from the 12 yard spot.  At the end it came down to a blocked shot that spun in by maybe a couple of centimeters. Well, that's football - too much like life.   Which brings me to a modest proposal.  Replace the thirty minute overtimes with as many 7-player 15 minute periods as needed to settle it.  Scoring should be much easier with fewer players.
