Expert "refutes" Dead Aid but can't do Math

From William Easterly:

A mass email went out to journalists yesterday from The Centre for Development and Population Activities: “Expert Refutes Bestselling "Dead Aid"; Available for Background and Interviews”. The available expert was Carol Peasley, President & CEO, The Centre for Development and Population Activities. Among the expert arguments refuting “Dead Aid” (from Peasley's piece in the Huffington Post) was that “Child deaths [in Malawi] have been reduced by nearly 100 percent (from 221 per thousand in 1990 to 120 in 2007).” I guess the expertise being made available did not include math.
