The information exchanged under REACH: A cost-sharing analysis

This article addresses the question of data-sharing mechanisms under REACH. The members of an information exchange forum have to share their data. This exchange requires the adoption of a compensation scheme: the owner of a data receives a monetary compensation in return for the access to his/her data. We are interested in the choice of a compensation scheme that would be fair for all participants. In order to answer this question, the exchange of information is modeled as in Dehez and Tellone [2010]. We list a collection of axioms for the compensation schemes. Various combinations of these axioms characterize several compensation schemes. Some of them coincide with well-known solutions of an associated cooperative game with transferable utility.
