It is well known that the EL-based CI has attractive properties such as data...

Game theory presents a useful analytical tool for addressing the problem of international cooperation and the formation of institutions. We first examine four problems that must be solved to achieve international cooperation: the common knowledge problem, agreement problem, compliance problem,...
