I haven't read Dambisa Moyo's book, but I did hear her speak and I think she is an articulate person. In terms of her broader message, I should preface by saying I would actually agree with Paul Collier and others like Jeff Sachs in the field who kind of dispute her notion that aid to Africa doesn't work. Even she has said she's been misquoted on that fact.
In terms of the bed net analysis, we know what to do when it comes to malaria: bed nets, ACTs, and spraying huts. We know how to eradicate malaria on this planet, and the globe has come together on that. We are actually close to complete coverage in terms of bed nets. We've had a lot of successes on that front. That's an example of the cost-effective, tangible solutions where we can invest and have an impact.
Should there be more production of bed nets within the continent of Africa? Yes.
