We have completed some additional research and analysis in our research into international charities:

• Interpreting the Disability-Adjusted Life-Year (DALY) metric: This page answers the following questions: What is a DALY? What are the limitations of the DALY metric? Why does GiveWell not focus exclusively on it?
• Converstations with international-aid experts: In the process of creating our report on international aid, we consulted with many people who shared their experience and expertise. This page provides a link to -- when available -- an audio recording and/or approximate transcript of our conversations. This page includes information from conversations with William Easterly, David Roodman, and Prabat Jha, among others.
• Issues related to developing-world drug quality: This is an important issue for any programs providing drugs for treatment or prevention.
• Standard of Living in the Developing World: This page seeks to answer the question "If a donor's funds save a live, what sort of life is saved?" It discusses subjective life satisfaction, incomes, mortality, morbidity, and what problems people in the developing world would most like addressed.
