Abstract: The mobile internet enables consumers to switch quickly across multiple scenarios. In this context, this paper explores the mechanism and boundary condition of how the impact of privacy violation further spreads to other seemingly unrelated consumption scenarios. Five experimental studies reveal that privacy violation enhanced consumers' preferences for unique products in subsequent consumptions. The underlying process driving this effect is that consumers perceived their personal boundaries have been invaded when encountering privacy violation and thus sought to rebuild their psychological boundaries by using unique products which symbol invisible boundaries. However, this effect does not exist among consumers with low privacy concerns.
