From its inception the Center for Global Development has made its mark on issues of aid and aid effectiveness. Many of our staff and non-resident fellows have been key contributors to a lively debate on the question of whether and how aid and the aid system work. This page brings together published and unpublished work in which authors propose new thinking about aid and the system, and new approaches to operationalizing aid transfers. The focus is on innovations, whether in ideas or operations. We aim to speed and broaden access to new ideas, and thereby increase the likelihood that good new ideas are turned into better aid programs—public and private, bilateral and multilateral, traditional and new donors.
