The purpose of this session was to showcase and discuss some of the recent research work that has been carried out on budget support. The meeting  touched on the current OECD/DAC sponsored budget support evaluations that are taking place in Mali, Tunisia, and Zambia. It will cover issues related to new evaluation methodologies, policy implications – responding to emerging or familiar unresolved questions such as the role of conditionality and the right objectives of budget support - and outstanding evidence gaps.
