Potential response of Mexican consumers to a Ban on genetically modified Maize imports

Mexico enacted a decree to ban the sale of genetically modified (GM) maize seed and maize for human consumption. Maize is particularly important to the average diet in Mexico as it is the main feed for the primary source of protein (poultry) and the main ingredient for the primary source of calories (corn tortillas). This study aimed to assess consumer awareness of the decree, support for the decree, and sensitivity of support given possible economic outcomes related to the decree. Additionally, we estimate the premiums consumers were willing to pay (WTP) for non-GM products relative to GM products (i.e., chicken meat, eggs, and corn tortillas). Results show that 54% of the Mexicans were unaware of the ban and that 77% of those aware supported the ban. Many consumers were willing to pay premiums to cover potential price increases due to the ban; however, not all low-income consumers would pay the potential premiums. Focusing on low-income consumers is particularly important, given they will likely be affected disproportionately more by the burden of increased food prices.
