Abstract
At the initial stage of planning conflict over infrastructure projects, players propose game form each other, and finally share the same game form. Once non-appropriate game form is shared, alternatives for agreement will be limited. In this paper, such iireversibility of planning conflict is focused on, and the model for describing players' behaviors at the initial stage. First, we constructed the model where players take actions depending on action norms. Then we analyze players' strategic choices of action norms. and find the relationshin between the types of planning conflicts and outcomes.
