A Reconsideration of Inter-Group Cooperation with Defect Problem, with an Application to the Climate Change Issue

In this paper, I reconsider this problem using knowledge gained from various disciplines ranging from psychology to social economics, to gain more insight. As an exercise, I apply the result to analyze the dealing with the climate change, while other applications are possible.
