The Economist Article on Cartels: Just one more fix

By Rosa M. Abrantes-Metz on March 27, 2014

The Economist discusses the incentives to join a cartel – even while trustbusters are getting better at breaking them up. In the article, they discuss methods to uncover cartels, including the use of screens, citing our colleague Rosa Abrantes-Metz:

“Some countries are employing eggheads to search for suspicious price patterns by screening markets. These statistical tests have proved most effective in markets with lots of data, such as financial benchmarks and derivatives, though they have also been useful in cement and fishing: they provided the first evidence of manipulation of the London Interbank Offered Rate (LIBOR) in 2008 and, last year, of foreign-exchange rates.

Not everyone is convinced by screening. The DoJ ditched it after concluding that it produced too many false positives. Grand-jury subpoenas can rock companies, says Scott Hammond, a former DoJ cartel-enforcement chief, now with Gibson, Dunn & Crutcher, another law firm. It is a mistake to unleash them based on tests that have falsely pointed to wrongdoing.

Rosa Abrantes-Metz of New York University’s Stern School of Business, whose number-crunching helped expose the LIBOR affair, thinks the Americans are too sceptical. She argues that market screening, like the medical sort, is useful as an indicator that prompts further investigation.”
