This working paper is based on an empirical investigation of corruption and illicit exchange related to the so-called “Lava Jato” or “Odebrecht” scandal. Focusing on former Peruvian President Alejandro Toledo and his laundering of bribes obtained from the construction giant Odebrecht, the analysis aims to test the usefulness of applying a network lens to better understand the mechanisms underlying grand corruption cases. It also aims to further illuminate the nexus between corruption and money laundering and the role of hidden and offshore financial infrastructures in facilitating the illicit schemes. 

The research used a combination of social network analysis and network ethnography techniques to explore the following questions: 

• How do money laundering activities and offshore financial infrastructures sustain corruption? 
• Who are the key actors involved, how do they interact and what is their division of labour? 
• How do actors and clusters govern the social-financial web of relations? 

Answering these questions with empirical evidence related to a specific case makes it possible to better understand how the connection between corruption and money laundering using offshore financial infrastructure works. It also supports the emerging understanding of corruption as a collective, transnational and financially advanced phenomenon.
