Although there is a vast body of academic and practitioner literature championing the importance of trust in long-term business relationships, relatively little has been written discussing the development and maintenance of trust in networks that are formed at short notice and that often operate for a limited period of time. However, some models of trust and trusting behavior in such “hastily formed relief networks” (HFRN) do exist, and the aim of this chapter is to consider the theoretical application of one of the most prominent examples – that known as “swift trust” – to a post-disaster humanitarian logistics scenario. Presented from the perspective of a HFRN, this chapter presents a discussion of the practical application of the swift trust model.
