What is the difference between the CPI and TIs Bribe Payers Index (BPI)?
While the CPI indicates perceived levels of corruption in countries, the BPI focuses on the propensity of firms from leading export countries to bribe abroad — providing an indication of the ‘supply side’ of corruption. The most recent Bribe Payers Index was published in October 2006 and can be found under: http://www.transparency.org/policy_research/surveys_indices/bpi.
