Cli-ents who have not worked with a particular consultancy face considerable risk when they place an order while lacking reliable information about the service quality they can expect. There is a strong link between trust and reputation, as the positive reputation of a consultancy can act as a substitute for a new client’s missing individual experience with the provider, fostering trust in the service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo facilitate trustworthy signals, we design and implement a novel reputation mechanism that carries a monetary weight stored on a blockchain network as an immutable, decentralized, and transparent ledger. Based on an implementation in the Ethereum network and subsequent evaluation, we conclude that the reputation mechanism can contribute to leveling information asymmetry and reducing risk while increasing reputation and trust. The mechanism lends itself to being used in other business-to-business scenarios that suffer from similar information asymmetries."}],"editor":[{"first_name":"Volker","last_name":"Nissen","full_name":"Nissen, Volker"}],"status":"public"},{"status":"public","type":"journal_article","extern":"1","file_date_updated":"2018-12-13T15:11:05Z","_id":"5614","department":[{"_id":"277"}],"user_id":"61579","intvolume":"         6","citation":{"short":"G.

In their efforts to take countermeasures against the threats posed by future natural disasters, the United Nations formulated the ?Hyogo Framework for Action?, which aims at assessing and reducing risk. This framework and a global review of disaster reduction initiatives of the United Nations acknowledge the need for information systems research contributions in addressing major challenges of natural disaster management. In this paper, we provide a review of the literature with regard to how information systems research has addressed risk assessment and reduction in natural disaster management. Based on the review we identify research gaps that are centered around the need for acquiring general knowledge on how to design IS artifacts for risk assessment and reduction. In order to close these gaps in further research, we develop a research agenda that follows the IS design science paradigm."}],"file":[{"content_type":"application/pdf","relation":"main_file","date_updated":"2018-12-13T15:11:05Z","date_created":"2018-12-07T11:50:26Z","creator":"hsiemes","file_size":2708161,"file_name":"Risk reduction in NDM - Revision 1.pdf","access_level":"open_access","file_id":"6044"}],"publication":"International Journal of Information Systems for Crisis Response and Management (IJISCRAM)","keyword":["Natural Disaster Management","Risk Reduction","Hyogo Framework","IS Design Science","Literature review"],"ddc":["000"],"language":[{"iso":"eng"}],"year":"2014","issue":"1","title":"Risk Reduction in Natural Disaster Management Through Information Systems: A Literature review and an IS design science research agenda","date_created":"2018-11-14T13:58:50Z"}]
