In this paper we study the problem of network exchange in trust based social networks. Network exchange is of two types: Specialized Exchange and Generalized Exchange, this can be characterized in terms of reciprocity, triads, graph motifs across these networks. Given the lack of standard metrics for Generalized Exchange, we propose a metric to quantify generalized exchange. We observe that the phenomenon of exchange can be used to differentiate networks. A key finding is that the manner in which the network is operationalized i.e., as cumulative network vs. active networks affects the measurement of exchange. Lastly we propose generative mechanisms for exchange in trust networks.
