The 2011 bribe payers index ranks the likelihood of companies from 28 leading economies to win business abroad by paying bribes. http://bpi.transparency.org/

The Bribe Payers Index is a unique tool capturing the supply side of international bribery, specifically focussing on bribes paid by the private sector. The 2011 Bribe Payers Index is the fifth edition of the index, ranking 28 of the world’s largest economies according to the likelihood of firms from these countries to bribe when doing business abroad. It is based on the results of Transparency International’s 2011 Bribe Payers Survey. This asked 3,016 senior business executives in 30 countries around the world for their perceptions of the likelihood of companies, from countries they have business dealings with, to engage in bribery when doing business in the executive’s country.
The 28 countries and territories ranked in the index are: Australia, Argentina, Belgium, Brazil, Canada, China, France, Germany, Hong Kong, Italy, India, Indonesia, Japan, Malaysia, Mexico, Netherlands, Russia, Saudi Arabia, Singapore, South Africa, South Korea, Spain, Switzerland, Taiwan, Turkey, United Arab Emirates, United Kingdom and United States. The countries include the largest economies in terms of outward trade and investment and together represent 78 per cent of global foreign direct investment (FDI) outflows and exports. They cover all countries ranked in the 2008 Bribe Payers Index, all G20 countries and other key regional economic trading powers.
South Africa scores 7.6
The Bribe Payers Index scores are anchored to the 0 – 10 parameters of the scale. A score of 0 corresponds with the perceptions of business people around the world that companies from that country always pay bribes when doing business abroad. A score of 10 corresponds with the perception that companies from that country never engage in bribery when doing business abroad. A score of 10 is therefore the benchmark which every country should aim for, as anything less than a 10 is an indication that companies from these countries are perceived to engage in bribery to some degree when doing business across borders. Scores that fall significantly short of a 10 indicate a serious problem, suggesting that companies from these countries are likely to engage in foreign bribery so frequently that it is recognised by the business executives whose perceptions constitute the 2011 Bribe Payers Index.
