Topics: Joint Decision Making in Dyad Calling Behavior

In this study, we investigate the joint decision making in wireless phone service consumption. Unlike other products and services, phone calls require two parties to jointly and simultaneously consume.  As both parties may pay the fees for communication and as phone calls are a way of joint consumption, the calling activity between two parties can be viewed as the outcome of a joint decision.  Using a large wireless telecommunication dataset, we estimate such a joint-decision model. We find that initiating callers enjoy more weights than the receiving callers in deciding the calling durations. We also find the call duration between a pair of consumers is positively affected by the strength of their tie measured by the number of their common contacts.  We demonstrate the implications of our results for designing the optimal pricing schemes.
