Drying and Storage to Improve Grain Product Quality: Evidence from Senegal

Stacy Prieto, Purdue University


This dissertation consists of two separate but related essays, each dealing with economic impacts of poor grain quality in sub-Saharan Africa (SSA). Inadequately dried grain can be susceptible to fungal growth after a few weeks of storage, resulting in spoilage and lower prices. Essay one examines trader and consumer ability to detect grain moisture content (MC) via a willingness to pay auction in which participants bid on maize unlabeled and labeled with its MC. In addition to spoilage/ lower prices, the fungi that grow on wet maize may produce aflatoxins, which are carcinogens. In essay two, we examine a combination of interventions designed reduce the MC and aflatoxin levels of maize among smallholder farmers.
