According to the OECD’s research on international bribery and corruption, most international bribes are paid by large companies, usually with the knowledge of senior management. Bribes are generally paid to win contracts from state-owned or controlled companies in advanced economies, rather than in the developing world, and most bribe payers and takers are from wealthy countries. Almost two-thirds of 400 cases analysed worldwide, occurred in just four sectors: extractive (19%); construction (15%); transportation and storage (15%); and information and communication (10%). Intermediaries, mostly agents or corporate vehicles, were involved in three out of four foreign bribery cases. This demonstrates the need for more effective due diligence and oversight of corporate compliance programmes. Governments should strengthen sanctions, make settlements public and reinforce protection of whistleblowers as part of greater efforts to tackle bribery and corruption.
