Private labels and platform competition

Saruta, Fuyuki (2023): Private labels and platform competition.

Abstract

This study examines the degree and manner by which first-party selling by a platform affects the profits of a third-party seller and a competing platform. After developing a model in which a third-party seller distributes goods through two competing platforms, with only one platform able to have a private label, we analyze first-party selling effects in both monopoly and duopoly platform cases. Our findings demonstrate the following. In a monopoly case, a platform consistently reduces the seller fee when introducing a private label. In a duopoly case, the two platforms will jointly raise or lower fees upon private label introduction. Additionally, first-party selling can either positively or negatively affect the competing platform's profit. Results suggest that competition among platforms might upset the influence of first-party selling on commission fees. Consequently, platforms might opt for first-party selling as a strategy to weaken commission fee competition and retail competition.
