Because consumers do not internalize the value of information they bring to others, their incentive for trying out the product can be socially insufficient. Given such a challenge, I study how the platform can improve social welfare by designing its recommendation policy. In a model with binary product quality and general trial-generated signals, I find that the optimal design features a U-shaped sequence of recommendation standards over the product’s life, and the optimal learning dynamic can involve temporary suspensions following negative consumer feedback when the product is young. Comparative statics and extensions explore how the optimal design adjusts under changes in trial informativeness, consumer arrival rates, and platform bias. My analysis also illustrates the usefulness of a Lagrangian duality approach for dynamic information design.</div></div>","PeriodicalId":48393,"journal":{"name":"Journal of Economic Theory","volume":"232 ","pages":"Article 106150"},"PeriodicalIF":1.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147397126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, it is always optimal to form a nested split graph at each stage, regardless of the discount function. Second, when the planner is sufficiently myopic, the optimal strategy uniquely generates a quasi-complete graph in each period.

The modal subject exhibits a preference for both early resolution of risk and ambiguity, but with only a minimal willingness to pay to realize either over late resolution. While preferences in both domains are positively correlated, the strength of that correlation varies based on ambiguity attitudes.
