These social networks help people cope with adversity but can also promote favouritism and corruption, posing a dilemma for development practitioners. Using Papua New Guinea's wantok system as a case in point, we develop a tripartite model for understanding how reciprocity networks function. This model provides insights into how practitioners can start designing context-specific responses to the challenges associated with informal systems of reciprocity.This report was commisioned by U4 Anti-Corruption Resource Centreapplication/pdfen-AU© 2020 Michelsen Institutehttps://creativecommons.org/licenses/by-nc-nd/4.0/basic servicesinformal institutionssocial normsPapua New GuineaOceania20202020-12-13Creative Commons Attribution-NonCommercialNoDerivatives 4.0 International licence (CC BY-NC-ND 4.0)
