This is the second episode of the 'Introduction to' series in which experts provide an overview of some of the key issues in the corruption field. In this episode Liz Dávid-Barrett, Dan Hough and Sam Power (all Centre for the Study of Corruption) discuss the leading theories for corruption analysis, including rational choice, collective action and social norms approaches.
