Hi Martha, At ACF we are working on a cost-effectiveness project. I have linked here two recent publications assessing cost-effectiveness of services to treat and prevent acute malnutrition. Cost-effectiveness of the community-based management of severe acute malnutrition by community health workers in southern Bangladesh [url]http://heapol.oxfordjournals.org/content/early/2012/08/23/heapol.czs070.full.pdf+html[/url] Protecting child health and nutrition status with ready-to-use food in addition to food assistance in urban Chad: a cost-effectiveness analysis [url]http://www.biomedcentral.com/content/pdf/1478-7547-11-27.pdf[/url] I hope this is useful for your research, let me know if you have any questions. Best, Chloe
