Blameworthiness in Strategic Games
This work addresses a foundational issue in game theory and multi-agent systems by formalizing blameworthiness, but it is incremental as it builds on existing notions of responsibility.
The paper tackled the problem of defining coalitional blameworthiness in strategic games using the principle of alternative possibilities, resulting in a sound and complete bimodal logical system for describing blameworthiness properties in one-shot games.
There are multiple notions of coalitional responsibility. The focus of this paper is on the blameworthiness defined through the principle of alternative possibilities: a coalition is blamable for a statement if the statement is true, but the coalition had a strategy to prevent it. The main technical result is a sound and complete bimodal logical system that describes properties of blameworthiness in one-shot games.
