Research output: Contribution to journalArticlepeer-review

Abstract

Information function method is a powerful tool for analyzing the information requirements of social welfare functions. However, the original information function provides only a coarse description of information structure. In this article, we propose a refinement of this method by changing the range of the information function. We also analyze the role of partially relevant information in preference aggregation through an application of the refined version of the information function method.
