摘要:Labels have been used to make food attributes transparent and to satisfy the increasing consumer demand for information about food credence values. Several types of prevalent U.S. food labels, their contributions, and the regulatory agencies behind them are examined in this paper. Additionally, studies dealing with the willingness-to-pay (WTP) for labeled products and the use of food labels as nontariff trade barriers are discussed. While unilateral labeling requirements are identified as a major form of non-tariff trade barriers, positive media influence and trust in the government and science are important factors that affect consumer WTP for food credence characteristics.
