Online feedback mechanisms harness the bi-directional communication capabilities of the Internet in order to engineer large-scale word-of-mouth networks. Best known so far as a technology for building trust and fostering cooperation in online marketplaces, such as eBay, these mechanisms are...

Commerce depends on buyers and sellers fulfilling their contractual obligations; mechanisms inducing such performance are essential to well-functioning markets. Internet-enabled reputation mechanisms that collect and disseminate consumer feedback have emerged as prominent means for inducing...

Online reputation mechanisms are emerging as a promising alternative to more established mechanisms for promoting trust and cooperative behavior, such as legally enforceable contracts. As information technology dramatically reduces the cost of accumulating, processing and disseminating consumer...
