Competition, Privacy, and Multi-Homing

Abstract

Two digital firms compete in prices and information disclosure levels. A consumer signing up to one firm's service decides how much personal information to provide. We find that firms essentially trade-off between consumer valuations and disclosure levels to determine their business strategies when consumers single-home. Under multi-homing, business strategies are more complex to assess and may completely shift compared to single-homing. All things being equal, implementing a strict privacy regime with no data disclosure can be optimal under single-homing, while a soft privacy regime with data disclosure may be preferred under multi-homing.
