The Millennium Development Goals require a doubling of funds for economic development by 2015. Examining innovative ways to secure these resources, this book sets out a framework for the economic analysis of different funding sources, applying the tools of modern public economics and considering the underlying political economy. It examines in turn a series of new and controversial proposals, including global taxes such as a carbon tax, a global lottery, pre-commitment of aid, increased private donations, and increased remittances by emigrants.
