Several articles have considered procedures for identifying markets susceptible to coordination. When a checklist of factors is considered, firms are usually assumed to be coordinating based on price. In this article, this approach is adapted to accommodate markets that may be coordinating on other focal points based on geographic or customer allocations. Some of the check-list features are still valid, but others need to be seen in a new light. New approaches for identifying tacit collusion in these markets are outlined. The example of the recent UK market investigation into cement is discussed as well as some other literature.
