Mobile computing has provided technology to an unprecedented user base and has created a market for applications that is expected to reach $77 billion by 2017, involving over 268 billion downloads. Nearly every download involves privacy messages that request permissions to access information such as contact, calendar, and location information. Recent cases have revealed that users are often surprised when they discover the permissions they have granted, which implies that not everyone reads them carefully. In this paper we propose a research agenda focusing on the decisions that users make about those permissions requests. Several theories provide promising antecedents to explain acceptance of privacy permissions. Nine propositions are presented, with three from each research bases from social, economic, and cognitive perspectives. The research agenda thus is a combination hybrid social/economic/cognitive approach. The agenda complements extant research that has focused on privacy calculus theory.
