Welcome to the June issue of “From Collusion to Competition.” This issue is dedicated to one of my very favorite topics: screening.

Screens have proven themselves effective by flagging many examples of potentially illegal behavior in financial and commodities benchmarks, several of these already confirmed.
In October of 2013 the OECD held a policy table on the use of screens, in which I had the honor of being one of the panelists (a summary of the roundtable and all individual submissions are available at http://www.oecd.org/daf/competition/exofficio-cartel-investigation-2013.pdf.) Even though opinions on screens were split among the member countries – and hence, the glass is both half empty and half full – the recognition of these tools has greatly increased over the last 5 years. 10 years ago for example, virtually no competition authority was discussing actually or potentially using screening. I can only expect this adoption trend to continue. In the future, cartel members will be much more careful not to leave incriminating messages and emails, meaning so-called direct evidence will be much harder to come by.
