Abstract
In this paper, we analytically prove that the sufficient condition in proposition 3 of [Zhou B, Zou T (2023) Competing for recommendations: The strategic impact of personalized product recommendations in online marketplaces. Marketing Sci. 42(2):360–376] never holds. We provide a new sufficient condition that actually holds, and discuss its implications.
