This paper is the online appendix for "Multiproduct Firms, Consumer Search, and Demand Heterogeneity". In this online appendix, we discuss a uniqueness and an existence of symmetric equilibria. First, we show that the system of the first-order-conditions has a unique solution. Then, we show that such first-order-conditions are sufficient for defining equilibrium prices for the specific distribution of match utilities. In the following context, we omit superscripts of density functions.
