Lawrence Macdonald, vice president for communications and policy outreach at the Center for Global Development, explains how CGD helped make $1 trillion available to developing countries after the global financial crisis. In the spring of 2009, the participation of developing countries in the global stimulus was made possible at the G-20 summit. But how much money was needed for the most vulnerable countries and where would it come from? Nancy Birdsall, president of CGD, prepared a note stating that they would need access to 1 trillion dollars to cope with the effects of the crisis. Birdsall then put together a blueprint for making the resources available. By channeling the plan to the right people and testifying in front of Congress, CGD helped to unlock the $1 trillion and make it possible for the IMF and World Bank to help vulnerable countries cope with the crisis.
