We leverage economic theory, network theory, and social network analytical techniques to bring greater conceptual and methodological rigor to understand how information is exchanged during disasters. We ask, "How can information relationships be evaluated more systematically during a disaster response?" "Infocentric analysis"—a term and approach we develop here—can (a) define an information market and information needs, (b) identify suppliers of information and mechanisms for information exchange, (c) map the information exchange network, and (d) diagnose information exchange failures. These steps are essential for describing how information flows, diagnosing complications, and positing solutions to rectify information problems during a disaster.
