Outline of Final Research Achievements |
In this study, we conduct laboratory experiments based on a one-shot gift exchange game in the context of firm-worker relationships. Our design admits two types of worker proposals on the contracts to his/her firm, defined as cheap talk. One contains only the desirable wage of the worker, while the other additionally contains his/her future effort. We find that worker preferences become biased in a more self-serving direction by making proposals in bargaining. That is, both types of worker cheap talk undermine reciprocity, thus deteriorating efficiency in an incomplete contract. Additional experiments show that the negative effect of cheap talk in bargaining is robust even for repeated interactions. By contrast, worker proposals including future efforts lead to successful coordination, which outweigh the negative effect on reciprocal behaviors.

Academic Significance and Societal Importance of the Research Achievements |
交渉を含む事前コミュニケーションの負の側面はこれまでにも指摘されてきたが、コミュニケーションが発話者自身の互恵的選好を毀損することで経済効率性を悪化させる可能性を示したのは本研究がはじめてである。とくに、本実験研究のベースとなったモラルハザード問題は、労使関係だけでなく、医師と患者、政治家と官僚、学生と教員の利害対立など、プリンシパル・エージェント関係全般に発生するものであり、本研究の応用範囲は広い。その成果は、プリンシパルとエージェントの利害対立を緩和するコミュニケーションのあり方や制度設計を検討する際の一助となるものである。
