Proposal of a model of commitment relationship formation introducing mechanisms of trust and betrayal.

Abstract

This paper examines the impact of trust and betrayal on networks. A generative model of a network of trust is proposed that introduces a mechanism of trust and betrayal. Assuming that a node is a person in the network and an edge is a commitment relationship between two persons, the proposed model generates a network by linking edges, which are commitment relationships, when two persons in the network have an opportunity to trade and trust each other. The results show that betrayal strengthens the ties in the network, but on the other hand increases the number of isolated nodes.
