"The purpose of aid is to reduce the size of the growth deceleration that African countries will experience. This is the result we are seeking to achieve with additional aid. Such results are hard to measure preciselywe would need to know the size of the growth deceleration in the absence of additional aidwhich is why Bob Zoellick suggested possible activities that the money could be spent on. Of course, each country will have to tailor its spending according to its particular needs and circumstances. When they do, we will, as we increasingly do now, develop monitorable indicators of performance to hold them and us accountable." This seems like a sensible proposal. Where do you expect the money to come from? Simply the World Bank? Other ideas?
