Working Paper 57: Mapping and strengthening the evidence base for anti-corruption Collective Action

This Working Paper provides a theoretical and practical contribution to strengthening the evidence base for anti-corruption Collective Action – i.e. collaborative efforts by diverse actors from the private sector, civil society and public institutions to address integrity challenges that no single actor can resolve alone. It combines a new conceptual framework for Collective Action initiatives, updated data and practical tools. Together, these will help researchers, practitioners and policymakers compare initiatives, test assumptions and design more effective collaborations. The paper provides insights into how Collective Action works in practice; the impact of different social and political environments; how to link Collective Action with real-world improvements in corruption prevention; and whether initiatives’ activities are actually contributing to their stated goals.
