I appreciate the publication of my first paper on economic benefits from suppressing malaria in Africa, printed in the MWJ of 2014 v5 n4 and cited on the MWJ webpage. I demonstrated that the return on investment in malaria suppression was about 6.5 to 1, a really good investment, don't you think?
Recently I published another paper based on a slightly larger set of data "Increased economic productivity after suppressing malaria transmission in 14 African countries" in the ejournal African Policy Journal, 2014 v9 Apr. This is a new journal run by students at Harvard Graduate School of Govt, and does not get picked up by the normal search engines, so I urge you to go to their website at African Policy Journal for their current articles.
Sorry Bart, this is the only way I can think of to get the article cited by you, since appartently you do not get notice of the articles in the Africa Policy Journal.
This second article indicated that the return on investments was very high, about 23 to 1, even higher than the ratio reported in the first paper. I have a third paper coming up which summarizes the first two papers, plus some other relevant data. It looks like malaria suppression is a really good investment for African countries.
