Claudia Baez Camargo, Head of Public Governance at the Basel Institute, talks to Liz Dávid-Barrett about her work on applying social norms theory to analysing corruption issues. The episode takes in examples of applied research in East Africa and Ukraine, while Claudia's thinking on corruption is also influenced by her upbringing in Mexico. Claudia describes some successes in altering social norms around corruption in health settings but equally some of the challenges in sustaining these initiatives. In addition, Claudia talks about her work analysing informal networks of corrupt actors as well as how we might use insights from behavioural science to improve anti-corruption interventions.
