膨胀的推荐
Inflated Recommendations
摘要
Biased recommendations arise naturally in markets with heterogeneous consumers. We study a model in which a monopolist offers an experience good to a population of consumers with heterogeneous tastes and makes personalized purchase recommendations. We provide conditions under which a firm makes welfare-reducing purchase recommendations with positive probability, resulting in inflated recommendations. We extend this insight to a setting in which an intermediary makes the recommendations, whereas a seller sets the retail price. Regulatory interventions that forbid inflated recommendations may lead to higher social welfare or may backfire.
中文摘要
在消费者偏好异质的市场中，偏见性推荐自然产生。我们研究了一个模型，其中垄断者向具有异质品味的消费者群体提供体验品，并做出个性化购买推荐。我们给出了企业在正概率下做出降低福利的购买推荐的条件，导致推荐膨胀。我们将这一见解扩展到中介机构做出推荐、而卖家设定零售价格的情境。禁止膨胀推荐的监管干预可能提高社会福利，也可能适得其反。
