Join us to celebrate the launch of Charles Kenny's latest book, Results Not Receipts: Counting the Right Things in Aid and Corruption. This work illustrates a growing problem: an important and justified focus on corruption as a barrier to development has led to policy change in aid agencies that is damaging the potential for aid to deliver results. Donors have treated corruption as an issue they can measure and improve, and from which they can insulate their projects at acceptable costs by controlling processes and monitoring receipts. Results Not Receipts highlights the weak link between donors’ preferred measures of corruption and development outcomes related to our limited ability to measure the problem. It discusses the costs of the standard anti-corruption tools of fiduciary controls and centralized delivery, and it suggests a different approach to tackling the problem of corruption in development: focus on outcomes.
