The document discusses the OECD Guidelines for Fighting Bid Rigging in Public Procurement. The guidelines help public officials reduce the risks of bid rigging in public tenders through careful design of procurement processes and detection of bid rigging conspiracies. Bid rigging illegally raises prices or lowers quality by groups of firms conspiring in public tenders, costing governments billions annually. The OECD runs training and reviews to assist adoption of the guidelines in fighting bid rigging.
