How agency alliances with complementors moderate quality assurance, product originality, and success in platform ecosystems

초록

Previous research on platform ecosystems has mainly focused on the relationships between users, complementors, and platform owners. However, the growing presence of agencies within platform-based markets has received little attention. Complementors are affiliated with an agency or work independently when offering products on a platform-based market. This study investigates the impact of agency affiliation on complementor success and explores how this relationship is influenced by product quality assurance and originality. Using a panel dataset of 188 mobile game applications from Google Play, we employ Generalized Least Squares (GLS) estimation to analyze agency alliance direct and moderating effects on complementor performance. Our findings indicate that an agency alliance is positively associated with complementor performance. However, it is better to work independently when complementors are capable of developing products that can differentiate themselves from competitors. This study contributes to the literature by shedding light on agencies' role as intermediaries within platform ecosystems and expands our understanding of platform dynamics. © 2025 The Authors
