Global warming is widely considered to be one of the most serious environmental problems for current and future generations. Moreover, the apparent failure of the Kyoto protocol to effect a meaningful reduction in greenhouse gas emissions has increased the importance of economic research into new ways to control global warming. In this exhaustive study, the authors break new ground by integrating cutting edge insights from three different perspectives: game theory, cost-effectiveness analysis and public choice. For each perspective the authors provide an overview of important results, discuss the theoretical consistency of the models and assumptions, highlight the practical problems which are not yet captured by theory, and explore the different applications to the various problems encountered in global warming. They demonstrate how each perspective has its own merits and weaknesses, and advocate and integrated approach as the best way forward. They also propose a research agenda for the future which encompasses the three methods to create a powerful tool for the analysis and resolution of global pollution problems.
