This study elucidates the role of control in the context of information privacy to develop a better understanding of the interactions between general privacy concerns and transactional privacy concerns. We posit that general privacy concerns moderate the effects of information collection and profile control on transactional privacy concerns, which in turn, influence willingness to delegate profile to Facebook apps. We test the research model in the context of Facebook apps installation. Results support our propositions. Theoretical contributions and practical implications for service providers and users are discussed.
