Gregory Kersten, Eva Chen, Dirk Neumann, Rustam Vahidov, and Christof Weinhardt. On Comparison of Mechanisms of Economic and Social Exchanges: The Times Model. In Negotiation and Market Engineering.

An e-market system is a concrete implementation of a market institution; it embeds one or more exchange mechanisms. The mechanisms are – from the economic point of view – disembodied objects (models and procedures) which control access to and regulate execution of transactions. E-market systems are also information systems which are information and communication technologies artifacts. They interact with their users; have different features and tools for searching, processing and displaying information. This work puts forward an argument that the study of e-markets must incorporate both the behavioural economic as well as the information systems perspectives. To this end the paper proposes a conceptual framework that integrates the two. This framework is used to formulate a model, which incorporates the essential features of exchange mechanisms, as well as their implementations as IS artefacts. The focus of attention is on two classes of mechanisms, namely auctions and negotiations. They both may serve the same purpose and their various types have been embedded in many e-market systems.
