Hello William,

Thanks for your response! If our proposal is successful, our study design enables us to measure the actual process of storage, include usage of pesticides, with detailed surveys. Your point about other welfare outcomes like healthcare and school fees is very important and we are mindful that we need to measure these outcomes, and not just quantity of maize stored, to be able to say anything meaningful about them.

Thank you for your comment. In addition to storing cowpeas, PICS bags have proven to be effective in storing a variety of crops, like maize (Williams et al, .2014, Baoua et al., 2014), pigeon peas (Vales et al., 2014) , cowpeas (Murdock et al., 2012) so these bags appear to be a promising storage technology.

We also envision our idea as enabling ROSCA members to share the costs, both monetary and non-monetary (like the common practice of re-drying stored maize periodically) associated with storing maize.
