Does Food Safety Information Impact U.S. Meat Demand?
构建了消费者对食品安全信息反应的理论模型，并应用于美国肉类消费数据，发现食品安全担忧对需求的影响总体较小且短暂，仅在重大事件期间有较大但短暂的冲击。
A theoretical model of consumer response to publicized food safety information on meat demand is developed with an empirical application to U.S. meat consumption. Evidence is found for the existence of pre-committed levels of consumption, seasonal factors, time trends, and contemporaneous own- and cross-commodity food safety concerns. The average demand response to food safety concerns is small, especially in comparison to price effects, and to previous estimates of health related issues. This small average effect masks periods of significantly larger responses corresponding with prominent food safety events, but these larger impacts are short-lived with no apparent food safety lagged effects on demand.
