Benford’s Law and Greece
Eddy Elfenbein, September 14th, 2011 at 9:17 amI’ve written about Benford’s Law before. The law predicts the frequency at which first numbers ought to appear in a random distribution. The law has been used to catch folks who have fudged their data.
Tim Harford highlights some researchers who have turned Benford’s Law on Greece’s economic data:
Manipulated data often fail to satisfy Benford’s Law. A manager who must submit receipts for expenses over £20 may end up filing claims for lots of £18 and £19 expenses – and the data will then contain too many ones, eights and nines. A forensic accountant can easily check this, and while not an infallible check (fraudster Bernard Madoff filed Benford-compatible monthly returns), it’s an indicator of possible trouble.
Which brings us back to the data Greece submitted to the European statistics agency. According to Rauch and his colleagues, Greek data are further from the Benford distribution than that of any other European Union member state. Romania, Latvia and Belgium also have abnormally distributed data, while Portugal, Italy and Spain have a clean bill of health.
Would a Benford-style analysis have helped spot Greece’s problems? In principle, yes. In practice, one wonders whether politics would have trumped statistics. A shame: according to Benford’s Law, Greece’s data were particularly odd in 2000, just before it joined the euro.

Retail Sales Unchanged
Eddy Elfenbein, September 14th, 2011 at 8:58 amThe futures indicate that the market will open higher this morning. The surprising news of this morning is that the Democrats lost the by-election to replace Anthony Weiner in New York’s ninth congressional district. This was seen as a relatively safe seat for the Democrats.
The retail sales report for August was unchanged from July. Wall Street was expecting an increase of 0.3% so this was a bit of a surprise. Some economists are concerned that the summer swoon had a larger impact on consumer spending than was first realized. Also, the initial retail sales report for July showed an increase of 0.5%. That was revised down to 0.3%.
The PPI report showed that wholesale inflation was flat last month which is welcome news for inflation hawks. The “core rate” rose by just 0.1%.
There’s more bad news for French banks this morning. These banks had the most exposure to the problems in Greece. Moody’s has downgraded the long-term debt of two major French banks, Société Générale and Crédit Agricole. Additionally, BNP Paribas is under review for a downgrade. Actually, some investors think Moody’s action could have been harsher.

The Power of Momentum
Eddy Elfenbein, September 13th, 2011 at 7:49 amIn a post yesterday, I criticized some sloppy analysis which tried to make overly broad statements based on long-term stock data. Here’s a good example of how long-term data ought to be used. The chart below shows the historical performance of stocks ranked by momentum decile (meaning 10% slices).
I took the numbers from Ken French’s data library. The reason why this is a more sound method is that we’re using long-term data to isolate one particular aspect of stock performance.
It turns out that stocks that are in motion have a very long record of continuing to stay in motion. Just to be clear, momentum is defined by performance over the 11-month period starting 12 months ago and ending one month ago. The month directly prior to each period is excluded. At the end of the month, the whole thing is repeated.
The deciles are perfectly ranked by momentum. The portfolio with the highest momentum did the best. The second-best came in second and so on, all the way down to the worst momentum which came in last.
