Accelerating Change Conference

The 2004 Accelerating Change Conference focused much more on current changes than last year’s attempts at providing long-term visions led me to expect.

The one topic that excited me was a virtual world called Second Life. While it might sound superficially like just a virtual Burning Man, the designers are serious enough about their nationbuilding to encourage commerce, both within the system and via currency exchanges such as The Gaming Open Market with other worlds. Their VP of Product Development Cory Ondrejka described Hernando de Soto’s book The Mystery of Capital as "must reading". They have been careful to insure that people have few incentives to take disputes arising in the virtual world to meatspace courts. For instance, they once banned a vandal from the game who owned a fair amount of land; they auctioned off the land and sent him a check for most of the proceeds – $1600.

Some of their customers are doing well enough in the virtual world that the company that runs Second Life has trouble offering them a salary good enough to compete with what they’re making in virtual life.

They don’t seem as concerned about the highly deflationary effects of their monetary policy as I expect they ought to be. Why will people buy their land (the sale of which seems to be their main source of income) if they can earn a safe and sure return by just holding the local currency?

The responsiveness of the company to citizen complaints (e.g. simplifying and later abolishing taxes in response to tax revolts) is fairly strong evidence that a non-monopolistic dictator is better than a democracy with monopoly power.

Tradesports compared to the pollsters

Once again, I feel somewhat humbled for underestimating the accuracy of presidential election markets. At least I was cautious enough to mainly bet against Bush winning states where he appeared to be behind, and against him winning 400 electoral votes, which made up for what I lost betting that Kerry would win the election and popular vote.

Assuming the preliminary results are accurately indicating the final results, Tradesports did quite well at predicting the elections (except for a few hours on Tuesday afternoon when it mistakenly reacted to exit polls). It’s Monday evening prices correctly indicated which presidential candidate would win each state. And it did a good job of indicating which states were closest (saying Iowa and Ohio were the least certain).

Manipulating futures markets

Alex Tabarrok writes about the apparent attempts to manipulate the Bush re-elected contract at Tradesports.com (which just dropped to exactly 50!), and CNBC has mentioned the same report today (with a denial from George Soros that he is responsible).

I want to warn people not to treat the failure of this manipulation as strong evidence that manipulation won’t have much effect on the reliability of the prices. If an experienced trader such as Soros tried to engage in this kind of manipulation, he would use a much more patient and cost-effective strategy than quickly driving the price down from 55 to 10.

To estimate the harm done by manipulation, we need to look at careful studies of how accurate markets have been, plus experiments such as the one Robin Hanson arranged. Note also that Robin’s attempt at a theoretical argument on this subject is unconvincing because it unrealistically assumes that traders aren’t risk-averse.

Greenspan and bubbles

According to an October 19 Bloomberg article, Greenspan said:

"Housing price bubbles presuppose an ability of market participants
to trade properties as they speculate about the future," and the
expense and difficulty of moving "are significant impediments to
speculative trading and an important restraint on the development of
housing price bubbles,"

I wonder how he would describe the Japanese real estate prices of the late 1980s.
It might not be a coincidence that the dollar has dropped against gold and other currencies the past couple of days.

I’m not yet willing to bet money that a significant housing bubble is developing in the U.S., but it wouldn’t take too much for me to decide it’s time for such a bet.

Efficiency of presidential election futures markets

Tyler Cowen and Mike Linksvayer discuss the somewhat confusing reaction of Bush wins futures to the first debate.

I have some different theories about what might have happened. The size of a typical trade seems to be a few hundred dollars or less, so the typical reward for being quick to exploit inefficient prices is probably in the $10 to $30 range. It’s fairly easy for me to imagine that the most sophisticated traders value their time enough that such rewards don’t cause them to react quickly. I’ve been making a small but steady return from fairly regular trades on Tradesports the past few months, but I only log in about once every two days.

Another possibility is that the best informed traders get their information by talking to undecided voters over several days after the debate.

Either way, as an experienced investor it doesn’t surprise me that markets are slow to react to information that isn’t very clear. Markets often show more frequent patterns of prices following a trend than I would expect from random behavior. I interpret this as evidence that some information gets reflected slowly in those prices. That doesn’t mean it’s possible to get rich by any simple trend following rule – enough of those trends are false signals created by traders trying to exploit the naive trend follower that it’s hard to get useful information out of the trends unless you combine it with good information about what the efficient price should be.
