Abstract

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.

墨西哥消费者对转基因玉米进口禁令的潜在反应

墨西哥颁布法令，禁止销售转基因玉米种子和供人类食用的玉米。玉米对墨西哥人的普通饮食尤为重要，因为它是主要蛋白质来源（家禽）的主要饲料，也是主要热量来源（玉米饼）的主要成分。本研究旨在评估消费者对该法令的认知度、对该法令的支持度，以及在该法令可能带来的经济后果下对支持度的敏感度。此外，我们还估算了相对于转基因产品（即鸡肉、鸡蛋和玉米饼）而言，消费者愿意为非转基因产品支付的溢价（WTP）。结果显示，54% 的墨西哥人不了解禁令，而了解禁令的人中有 77% 支持禁令。许多消费者愿意支付保险费，以弥补禁令可能导致的价格上涨；但并非所有低收入消费者都愿意支付潜在的保险费。关注低收入消费者尤为重要，因为他们受到食品价格上涨的影响可能更大。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
