Researchers in political science, policy analysis, and policy for specific areas examine policy formulation tools. Their topics include tools for coping with complexity and future uncertainty, computerized models as tools for assessing the future of complex systems, whether cost-benefit analysis is a tool that is both useful and influential, a developing country perspective on policy formulation tool use in emerging policy spheres, and the MARKAL energy model as an example of using computerized models in different policy formulation venues.
