This article provides an encyclopedic survey of the platform strategy literature and is organized around launch strategies, governance, and competition. A platform strategy is the mobilization of a networked business platform to expand into and operate in a given market. A business platform, in...

We consider dynamic competition among platforms in a market with network externalities. A platform that dominated the market in the previous period becomes “focal” in the current period, in that agents play the equilibrium in which they adopt the focal platform whenever such equilibrium...

We consider platform competition in the presence of small users and a user-group. One platform enjoys a quality advantage and the other benefits from favorable beliefs. We study whether the group mitigates the users' coordination problem -- i.e., joining a low-quality platform because they...

An increasingly common practice among media platforms is to provide premium content versions with fewer or even no ads. This practice leads to an intriguing question: how should ad-financed media price discriminate through versioning? I develop a two-sided media model and illustrate that price...

This paper presents a model in which a monopoly platform not only operates a marketplace intermediating direct transactions between consumers and third-party sellers, but also sells its first-party products at the marketplace, which is designated herein as platform encroachment. When...

This paper examines a monopoly platform's two-sided pricing strategies in a setting with seller competition, which gives rise to not only positive cross-side network effects between buyers and sellers, but also a negative same-side network effect among sellers. We show that platform pricing...

We consider platform competition in the presence of small users and a usergroup. One platform enjoys a quality advantage and the other benefits from favorable beliefs. We study whether the group mitigates the users' coordination problem i.e., joining a low-quality platform because they believe...

In this paper, we analyze the impact of cooperation on R&D investments in a two-sided market, where platforms compete in quantities. We show that if indirect externalities are of a moderate magnitude, the threshold degree of spillovers above which cooperation spurs R&D investments and enhances...

We consider a heretofore unexplored explanation for why platforms, such as Internet service providers, might impose download limits on content consumers: doing so increases the degree to which those consumers view content providers products as substitutes. This, in turn, intensifies competition...

We consider a heretofore unexplored explanation for why platforms, such as Internet service providers and mobile-phone networks, offer plans with download limits: through one of two mechanisms, doing so causes the providers of the content consumer purchase to either reduce their prices or...
