This document discusses food policy and international markets. It notes changes in the agri-food system including a move from commodities to differentiated products due to changes in consumer preferences, technological progress, global competition, and decreased government support for agriculture. Examples of new products include genetically modified, organic, sustainable, natural, rBST-free, and cage-free products. Certification and labeling are critical for product differentiation, consumer decisions, and capturing price premiums. Labeling policy is also important for research and development and market access. Labeling of genetically modified products is highly controversial with different policies between regions. Food policy research at the University of Nebraska-Lincoln examines various related issues.
