Do Free Goods Stick to Poor Households? Experimental Evidence on Insecticide Treated Bednets
TL;DR: In this article, the authors quantify the effect of the endowment effect on the resale of in-kind transfers and show that very few nets will be resold by recipient households.

Samuel Mutiga,Vincent M. Were,Vivian Hoffmann,Jagger Harvey,Michael G. Milgroom,Rebecca Nelson +5 more
TL;DR: Investigation in maize intended for immediate human consumption in eastern Kenya found a higher occurrence of aflatoxin was associated with smaller maize farms, lower grain yield, and monocropping systems, while a larger magnitude of the toxin was observed in the subhumid agroecological zone.
