虚高的推荐

Inflated Recommendations
The RAND Journal of Economics · 2025 · Martin Peitz、Anton Sobolev

中文摘要

在消费者异质的市场中,有偏的推荐会自然产生。我们研究这样一个模型:垄断者向偏好异质的消费者群体提供一种经验品,并给出个性化的购买推荐。我们给出了企业以正的概率作出降低福利的购买推荐的条件,从而导致虚高的推荐。我们将这一洞见拓展到由中介作出推荐、而由卖方制定零售价的情形。禁止虚高推荐的监管干预可能带来更高的社会福利,也可能适得其反。

Abstract

ABSTRACT 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.
