Economic and health impacts of genetically modified eggplant: Results from a randomized controlled trial of Bt brinjal in Bangladesh por Ahmed, Akhter, Hoddinott, John F., Abedin, Naveen, Hossain, Nusrat Z.

“…The differences in net yields were driven by two outcomes: the quantity harvested was higher on Bt brinjal fields, by 114 kilograms per farmer; and after harvesting, fewer fruits were discarded because of damage due to pests and diseases, by 40 kilograms per farmer. Increased production, together with a 14 percent increase in price and a 10 percent reduction in costs, leads to a substantial increase in profits from cultivating Bt brinjal for treatment farmers compared with conventional brinjal produced by control farmers. …”
