Criticism of 'The Market for Aid'

Leah Pinto blogs at NextBillion.net to say that she doesn't believe that increased competition between aid agencies will make them more efficient. Well, that's true, but I think she's missed the point - competition may not increase efficiency, but if aid agencies are properly evaluated, with the best ones expanded and the worst shut down, that would be another matter.
Leah also proposes that the private sector be strengthened and that sustainable microfinance institutions be established.
