Published in the peer-reviewed journal Governance, this paper interprets informal networks as investments made by citizens and business people to cope with the public sphere. Informal networks often orchestrate corruption, connecting public and private actors. The paper aims to understand their key characteristics, scopes, and functional roles.

Donors, governments and anti-corruption practitioners seeking alternative tools to address systemic corruption are increasingly turning to behavioural science. Behavioural anti-corruption approaches appear promising because they respond to a growing body of descriptive evidence on how certain social norms and mental models drive corruption, particularly in fragile contexts. Interventions that target social norms and seek to shift people’s behaviours away from corrupt practices could be more effective and long-lasting than ones that, for example, simply add more regulations and controls.

This report relates to the research project Addressing bribery in the Tanzanian health sector: A behavioural approach. As part of the project, a pilot behavioural intervention was implemented at a Tanzanian hospital that aimed to shift hospital users’ and health providers’ attitudes and perceived social norms around gift-giving. It also aimed to reduce actual exchanges of gifts.

This Working Paper provides guidance on developing anti-corruption interventions based on a Social Norms and Behaviour Change (SNBC) approach. Still a relatively nascent field, SNBC interventions typically address social norms that make corruption acceptable or expected, and attempt to influence behaviours away from corrupt practices. 

This Problem Analysis is a review of the efficacy and opportunities for using social norm and behaviour change (SNBC) approaches to combat illegal wildlife trade (IWT) and other natural resource-related corruption.

Why do many countries still struggle with high levels of corruption, in spite of years of investment in anti-corruption programmes and even where the right laws, rules and institutions are in place?

We believe one reason is that anti-corruption laws and policies are too often focused narrowly on individuals, rather than networks of individuals.
