Intransitivity

From today’s NYT

“Even though DeLay has nothing to do with Frist, and Frist has nothing to do with Abramoff, how does it look? Not good,” said William Kristol, a key conservative strategist and editor of The Weekly Standard.

Unfortunately for Kristol’s rhetorical exercise, the relation “has nothing to do with” is not transitive, a fact of which he is presumably aware, given this choice of example.

From the previous para in the same story

the string of ethical issues so close together – including the indictment and continuing investigation of the Republican lobbyist Jack Abramoff, who was close to Mr. DeLay … is a source of anxiety in Republican circles.

Saddam trial

Gary Bass in the NYT comments on the possibility that Saddam could be sentenced to death and executed for a 1982 massacre of about 100 villagers, without ever being brought to trial on the main array of charges against him, including killing political rivals, crushing the Shiite uprising in southern Iraq in 1991, invading Kuwait in 1990 and waging the genocidal Anfal campaign against the Kurds in 1988, including gassing Kurdish villagers at Halabja. As Bass says,

 A thorough series of war crimes trials would not only give the victims more satisfaction but also yield a documentary and testimonial record of the regime’s crimes.

But looking at this list raises a more basic question. Why hasn’t Saddam been charged with any crime more recent than 1991?[1]. In the leadup to the war, and in its aftermath, it was routinely claimed that Saddam’s regime, at the time it was overthrown was among the most brutal dictatorships in the world. Even among opponents of the war, including myself, hardly anyone doubted that the regime routinely practised murder and torture. Why then aren’t there any charges covering this period? Presumably both documents and witnesses are more readily available than for a crime committed more than twenty years ago.

Meeting the economists

I’ve been at the Conference of Economists in Melbourne for the last few days. I econobloggers, Stephen Kirchner and Andrew Leigh[1], as well as Andrew’s co-author Justin Wolfers and lots of old friends and sparring partners. I gave a paper on Learning and Discovery, an attempt with Simon Grant to unravel the knotty problem of unknown unknowns. You can read a more accessible summary Unknownunknowns0509here

Olivier Blanchard gave quite an interesting paper on European unemployment, on which I’ll try to comment further. I also found out what’s wrong (and right) with the bootstrap (an econometric technique) and saw an interesting ranking of economics departments, which showed that one of my former homes was ranked #2 in Australia on per capita research output just at the time when it was closed down as part of the reform process.

The singularity and the knife-edge

I’ve been too busy thinking about all the fun I’ll have with my magic pony, designing my private planet and so on, to write up a proper review of Ray Kurzweil’s book, The Singularity is Near. The general response seems to have been a polite version of DD’s “bollocks”, and the book certainly has a high nonsense to signal ratio. Kurzweil lost me on biotech, for example, when he revealed that he had invented his own cure for middle age, involving the daily consumption of a vast range of pills and supplements, supposedly keeping his biological age at 40 for the last 15 years (the photo on the dustjacket is that of a man in his early 50s). In any case, I haven’t seen anything coming out of biotech in the last few decades remotely comparable to penicillin and the Pill for medical and social impact.

But Kurzweil’s appeal to Moore’s Law seems worth taking seriously. There’s no sign that the rate of progress in computer technology is slowing down noticeably. A doubling time of two years for chip speed, memory capacity and so on implies a thousand-fold increase over twenty years. There are two very different things this could mean. One is that computers in twenty years time will do mostly the same things as at present, but very fast and at almost zero cost. The other is that digital technologies will displace analog for a steadily growing proportion of productive activity, in both the economy and the household sector, as has already happened with communications, photography, music and so on. Once that transition is made these sectors share the rapid growth of the computer sector.

Amazing!

A great win for the Swans with a game-saving mark in the final seconds. And finally a reward for the South Melbourne faithful who’ve gone a biblical lifetime (threescore years and ten, with a couple over) without a flag. Tim Dunlop is similarly stunned.

A trillion dollar war (crossposted at CT)

Before the Iraq war began, Yale economist William Nordhaus estimated the likely cost at between $100 billion and $2 trillion. At the time most of the interest lay in the fact that the bottom end of the range was twice as much as the $50 billion estimate being pushed by the Administration. But with a couple of years’ experience to go on, Nordhaus’ upper range is looking pretty accurate. Assuming that Bush ‘stays the course’, it’s safe to estimate that the war will cost the US at least $1 trillion by the time all the bills come in, and it could easily be closer to $2 trillion.

Lurker Week

Via a chain of links starting at Crooked Timber, I found out that it was Lurker Day on September 21. This is the day when readers of blogs who don’t normally post comments are supposed to do so, ideally with some sort of comment about why they read the blog, how they found it and so on. Given that it’s Friday afternoon now, I’m making it a week instead of a day.

Don’t be put off by the term ‘lurker’ which dates back to the days of newsgroups, when there was a feeling that everyone ought to join in[1]. There’s nothing wrong with reading the blog and not commenting, but I’d really like to know that my page views aren’t all robots and spiders, so a short message from you, just this once, would give me lots of encouragement. Feel free to use a pseudonym; most of the regular commenters do.
