The existence of environmental dilemmas and political conflicts leads us to appreciate the need for individuals and groups to behave strategically in order to achieve their goals and maintain their wellbeing. Global issues such as climate change, resource depletion, and pollution, as well as revolts and protests against corporations, regimes, and other central authorities, are the result of increased levels of externalities among individuals and nations. These all require policy intervention at international and global levels.
