Public corruption is a crime that involves at least two parties, the public officer or politician who is offered or asks for a bribe in exchange for an irregular act in the course of his or her professional activities which favours a private actor, a citizen, or a company. Most research in criminology on corruption and anti-corruption is limited to the public sector partner in corruption. Recently, due to pressure from American and British anti-corruption legislation, companies have started to worry about their policy. In this contribution we present the results of an empirical study of the perceptions of corruption and anti-corruption policy in the private sector. The research is based on interviews with key figures from the Belgian business world and a quantitative questionnaire of company lawyers working for companies located in Belgium. These results form part of a research project on the tipping points of anti-corruption policy in the public and private sectors that has been set up in 2008.
