Fighting Corruption through Collective Action – A Guide for Business and its companion web portal were launched in June 2008. This new guide outlines multiple options for combating market corruption based on proven “how-to” examples from many regions and sectors. Cases from a diverse group of countries, including Mexico, Germany and Pakistan, are detailed in the guide, as well as a range of tools, such as decision trees and process steps, that help users to tailor collective action frameworks to their specific circumstances and needs.
