We live in turbulent times. In a post-crisis world, we need innovative ideas and a fresh look at a broad range of development issues. A research and policy area in urgent need of a fresh approach and new ideas is development finance, broadly defined to include domestic resource mobilization and financial sector development as well as foreign aid and other external capital flows. In this context, it is not surprising that the global financial ‘architecture’ is currently once again being questioned and the whole development finance ‘system’ (or ‘non-system’) is being re-examined.
