Wolfers on New Hampshire and Clemens
I had a long conversation about prediction markets and data-crunching with Justin Wolfers at the Money:Tech conference last week, which continued over the weekend via email. Given that we’re both bloggers, it seems time to bring the debate out into … Continue reading

Counterfeiting Statistics: Still Atrocious
Do you remember the atrocious and disappointing OECD report on counterfeiting? Rather than come up with a realistic estimate for the value of counterfeits traded worldwide, it came out with a hugely exaggerated "ceiling" of $200 billion. All the same, … Continue reading

Payrolls: An Apology
Why did I pick today to resuscitate my extremely occasional series of blog entries on the uselessness and irrelevance of the payrolls report? In reality, it would seem that the report was responsible for the decimation of technology stocks, the … Continue reading

Payrolls: Still Best Ignored
The day after the Iowa caucus, with the media full of horse-race coverage of presidential politics, is a good one to miss the news of the monthly jobs report. Good. The non-farm payroll report, which comes out on the first … Continue reading

Dubious Statistics Watch: Thanksgiving Retail Sales
Bloomberg News seems to be running two stories – on the same subject, and by the same authors – at the same time. The first has quite an apocalyptic headline: "U.S. Consumers Spent Average of 3.5% Less on Shopping". Which … Continue reading

Gay Demographics Datapoint of the Day
Gary Gates: Since 1990, the Census Bureau has tracked the presence of same-sex "unmarried partners," commonly understood to be lesbian and gay couples. From an initial count of about 145,000 same-sex couples in 1990, the 2006 data show that this … Continue reading

Las Vegas vs the Law of Large Numbers
Nassim Taleb likes to use Las Vegas as an example of a mathematical odds-based business which exists in economic theory much more often than it exists in real life. If you run a bunch of casinos with hundreds of thousands … Continue reading

The Limits of Empiricism
Two interesting reviews today: David Leonhardt on Ian Ayres, and Daniel Davies on Steven Levitt and Roland Fryer. There’s a meme catching hold – think Freakonomics and Moneyball – which says that rigorous empirical analysis can reveal otherwise-unobtainable insights. But … Continue reading

Stretching Credulity on Identity Theft Costs

apropos the Live Earth estimates of 2 billion viewers: "Is it OK to cite
questionable estimates in service to a good cause?" The answer, of course,

Realistic Counterfeiting Numbers Emerge
I’ve been waiting over two years for this. Since the end of 2004, I’ve had a close interest in counterfeiting statistics, and eventually I wrote a long piece in June 2005 saying that all counterfeiting statistics are bullshit. Towards the … Continue reading
