Information Transparency, Multihoming, and Platform Competition: A Natural Experiment in the Daily Deals Market

Abstract

Platform competition is shaped by the likelihood of multi-homing (i.e., complementors or consumers adopt more than one platform). To take advantage of multi-homing, platform firms often attempt to motivate their rivals’ high-performing complementors to adopt their own platforms, or attempt to prevent their current complementors or consumers from multi-homing. In this paper, we study the effectiveness of such strategies in the context of the online daily deals market. We first develop a game-theoretical model that takes into account multi-homing on both sides of the market and strategic behavior of all participants—consumers, platform firms, and merchants. We then derive hypotheses and empirically test them. The empirical analysis leverages a policy change of Groupon that reduced information transparency and weakened LivingSocial’s ability to identify popular Groupon deals and poach the corresponding merchants. Our results show that limiting information transparency reduced multi-homing: after the policy change, LivingSocial copied fewer deals from Groupon and increased its efforts to source new deals. Consequently, industry-wide deal variety increased. We also observe a seesaw effect in that reduced merchant-side multi-homing led to increased consumer-side multi-homing, thereby strengthening LivingSocial’s market position on the consumer side. Overall, after accounting for changes in both lifetime value of the customer base and acquisition cost of merchants, Groupon’s policy change reduced LivingSocial’s profitability.
