Heterogeneous Consumer Reactions to Health News
研究了消费者对鱼类健康新闻的反应差异，发现仅16%的消费者对特定新闻有强烈反应，且这些消费者更关注一般健康信息。
Abstract We investigate heterogeneity in how consumers react to health‐related media information. Our specific focus is on news relating to fish and the consumption of different types of fish. We specify a dynamic empirical model that allows for pervasive heterogeneity in all basic parameters of consumer behavior, as well as in how consumers react to information. We estimate the model using a unique household panel tracking consumption, prices, news stories, and media habits over 24 quarters. We find that only 16% of consumers react to news that is specific to fatty fish. These consumers have a large reaction to such news, with a modest initial over‐reaction. Furthermore, these consumers are also more attentive to general media information about the healthiness of fish.
