This book presents insights from the Nordic, mostly Swedish, journeys towards controlling corruption. It challenges the assumption that corruption must be attacked in a direct way with harder punishments and stricter rules (principal-agent theory). Instead Rothstein argues for an indirect approach - policies that create a social contract based on a problem of collective action. Such policies are likely to 'undermine systemic corruption by creating an implicit contract between citizens and the state to produce common goods', e.g. handling taxes, universal education, meritocracy, gender equality, supreme audit office, welfare state programs. It was not always easy to comprehend the text but the data and arguments are very interesting. Strongly recommend for those in the good governance sector.
