Frequently, descriptions of corruption are over-simplified, reducing them to isolated acts between two different agents: the one who offers a bribe, and the one who receives it. In other words, as the often repeated quote puts it: “it takes two to tango”. Yet in reality, corruption is a complex crime. Many modern cases of corruption are the result of a series of actions and agreements to subvert government processes, influence or manipulate policies and oversight mechanisms, extract rents, and hide the proceeds. Committing an act of corruption requires the complicity, and secrecy, of a group of individuals and organizations. In other words, a corruption network.
