This paper studies the role of a recommender's career concerns in his long-run relationship with a consumer when the recommender has a private type in his expertise. An informed type's expertise is valuable for ongoing purchasing decisions of the consumer, whereas an uninformed type lacks the expertise. The uninformed type cannot mimic the informed type, suggesting that the informed type can build a reputation for competence and that an equilibrium should exhibit information transmission. Nonetheless, I find that the relationship completely breaks down if the recommender is sufficiently patient and thus has stronger career concerns. Moreover, this occurs even when the uncertainty of expertise is arbitrarily small.
