Formulation of commons dilemma: Dawes model reconsidered

Abstract

This paper examines Dawes (1975) model on commons dilemma (CD) situation and proposes an alternative model which formulates CD. Firstly, it makes clear that Dawes model does not have the characteristics of CD. Secondly, it specifies “resource unit condition” which models of commons dilemma must satisfy. Thirdly, it presents CD model, which is obtained by setting the condition in Dawes model. And lastly, it examines some nature of the proposed model and find that in CD situation, fine is distributed proportionally to each player's property.

Key words:

• social dilemma
• commons dilemma
• group size
• resource unit condition
• temptation of defection
• mathematical model
