%0 Journal Article %T Ensuring Trust in One Time Exchanges: Solving the QoS Problem %A Bernardo A. Huberman %A Fang Wu %A Li Zhang %J Physics %D 2005 %I arXiv %X We describe a pricing structure for the provision of IT services that ensures trust without requiring repeated interactions between service providers and users. It does so by offering a pricing structure that elicits truthful reporting of quality of service (QoS) by providers while making them profitable. This mechanism also induces truth-telling on the part of users reserving the service. %U http://arxiv.org/abs/cs/0512034v1
