As well as being accountability mechanisms in their own right, donor agencies face a range of other domestic accountability structures, such as elected legislatures, independent audit offices, the law, relationships to other government departments or ministries, and formal channels for engaging domestic stakeholders. These structures impact both positively and negatively on the way that agencies are able to deliver aid. This potentially reduces the potential for the agencies to implement the Paris Declaration principles and so could affect the delivery of more effective aid. This project aims to develop a pilot framework to analyse the impact that these different accountability structures might have. It will test the framework by looking at the impact of the legislatures on DFID and USAID.
