Decision makers in health, public policy, technology, and social science are increasingly interested in going beyond ‘one-size-fits-all' policies to personalized ones. Thus, they are faced with the problem of estimating heterogeneous causal effects. Unfortunately, estimating heterogeneous...

Internet recommender systems are popular in contexts that include heterogeneous consumers and numerous products. In such contexts, product features that adequately describe all the products are often not readily available. Content-based systems therefore rely on user-generated content such as...

Online recommendation systems recommend products with widely different prices than that of their focal products. While conventional wisdom suggests that consumers may prefer lower priced recommendations, prior literature also indicates that consumers may not accept such products if their prices...

We study product recommendations in an online environment where a firm provides strategic product recommendations to consumers. We develop an analytical framework to integrate recommendations into the consumer product search process. The firm sells two imperfectly substitutable products with...

We develop a general agent-based modeling and computational simulation approach to study the impact of various factors on the temporal dynamics of recommender systems' performance. The proposed agent-based simulation approach allows for comprehensive analysis of longitudinal recommender systems...

Online behavioral advertising, on websites and in online applications, requires companies to make intricate trade-offs between promises of increased revenue and potential risks for alienation of consumers. To guide companies in making such trade-offs, we answer the research question: How do...

I study a platform-mediated two-sided matching with incomplete information. Platform users voluntarily disclose their taste information to the platform, and the platform aggregates and redistributes the collected information back to each user before they form matches. I characterize conditions...
