Abstract

In SSA, if maize moisture content cannot be detected, traders and consumers have no incentive to dry maize to ≤ 13.0 percent moisture, resulting in fungal growth and aflatoxin contamination. Using an experimental auction in SSA, we elicit trader and consumer WTP for maize labeled with varying moisture contents. Participants revealed a preference for drier maize when they knew the moisture content, but could not distinguish between unlabeled maize dried to ≤ 13.0 percent moisture and 14-15.9 percent moisture.
