Vertical Integration, Exclusivity, and Game Sales Performance in the US Video Game Industry

Abstract

This paper empirically investigates the relation between vertical integration and video game performance in the US video game industry. For this purpose, we use a widely used data set from NPD on video game montly sales from October 2000 to October 2007. We complement these data with handly collected information on video game developers for all games in the sample and the timing of all mergers and acquisitions during that period. By doing this, we are able to separate vertically integrated games from those that are just exclusive to a platform. First, we show that vertically integrated games produce higher revenues and sell more units at higher prices than independent games. Second, we explore the causal effect of vertical integration and find that, for the average integrated game, most of the difference in performance comes from better release and marketing strategies that soften competition and not from ex-ante differences in video game quality. We also find that exclusivity is associated with lower demand. Our estimates suggest that consumers value vertical integration features in their games between 4 and 34 dollars per game.

When Old Meets New: Wholesale and Agency Models in the Market for Printed and Electronic Books

“…However, it has also been demonstrated that revenue sharing may not be a panacea for double marginalization. For instance, if costly advertising becomes critical to boosting sales, it can be shown that royalty payments based on a revenue-sharing formula would not coordinate the channel [4,5]. Along the same line, this work also shows that revenue-sharing arrangement does not automatically translate to lower margins and a lower retail price for e-books.…”

The Impact Of Platform On Global Video Game Sales

“…This is most clearly seen when the platform producers also develop the content for the platform (Claussen, 2011;Gil & Warzynski, 2010). Halo is a top-selling video game franchise which has capitalized on this phenomenon.…”

Strategic timing of entry: evidence from video games

“…that require greater ex ante investment. Publishers decide whether to vertically integrate into game development versus outsourcing it to third-party developers (Gil and Warzynski, 2010).…”
