Abstract

In this paper, the authors examine strategic communication including ambiguous utterances. Recently, game theoretical approaches are introduced in the study of pragmatics. Parikh's paper is considered as one of the representative studies. He shows that there exist equilibria including an ambiguous utterance as a part of the equilibrium strategy in his model. However, his model has some limitations. First of all, in his model, interests between the sender and the receiver perfectly coincide, and secondly he analyzes with a static solution concept. In this paper, Parikh's model of ambiguous utterances is extended by changing the degree of coincidence of interest between the sender and the receiver, and is analyzed by evolutionary dynamics. The authors found that ambiguous utterances can be a stable outcome with certain conditions. Agent-based simulation also confirmed this finding.
