Process of Group Decision Making under Decision Rule

Abstract

In group decision making among the residents, they may reveal their preference with considering the others' revealed preference. This influences the process of group decision making. This study focuses on the interaction between group decision process and decision rule. As a result, even if the residents are homogenous in terms of preference, the residents reserve to reveal their preference under some rule. This suggests that it is impossible for those who are not participants to interpret the residents' preference by using the fact that they reserve to reveal their preference.
