From Blogs.worldbank.org:
In Doha last month, CommGAP learned about the work of 5th Pillar, which has a unique initiative to mobilize citizens to fight corruption. In India, petty corruption is pervasive – people often face situations where they are asked to pay bribes for public services that should be provided free. 5th Pillar distributes zero rupee notes in the hopes that ordinary Indians can use these notes as a means to protest demands for bribes by public officials. I recently spoke with Vijay Anand, 5th Pillar’s president, to learn more about this fascinating initiative.
According to Anand, the idea was first conceived by an Indian physics professor at the University of Maryland, who, in his travels around India, realized how widespread bribery was and wanted to do something about it. He came up with the idea of printing zero-denomination notes and handing them out to officials whenever he was asked for kickbacks as a way to show his resistance. Anand took this idea further: to print them en masse, widely publicize them, and give them out to the Indian people. He thought these notes would be a way to get people to show their disapproval of public service delivery dependent on bribes. The notes did just that. The first batch of 25,000 notes were met with such demand that 5th Pillar has ended up distributing one million zero-rupee notes to date since it began this initiative. Along the way, the organization has collected many stories from people using them to successfully resist engaging in bribery.
