For several staple grains, the share of trade that originates in and is destined for countries that have approved genetically engineered (GE) varieties continues to expand as a share of total trade. As the GE-world expands, non-adoption of GE technology may isolate a market, effectively eliminating a growing source of food. This research seeks to quantify the impacts of GE approval and non-approval on food prices and access to food from abroad in importing countries. We show that non-adoption of GE technology reduces a country's access to imports and raises its prices. Not only do non-approving importers fail to receive the full benefits of agricultural expansion resulting from genetic engineering, the countries are worse off relative to a world in which the technology never existed.
