Designing public policies : an approach based on multi criteria analysis and computable general equilibrium modeling This book presents a methodological approach for the joint design of economic and environmental policies. The starting point is the observation that in practice policy makers do not usually have a well defined objective but they are typically concerned about a number of economic and environmental indicators that conflict with each other. In view of this policy making is addressed by combining two separate analytical approaches: multiple criteria decision making (MCDM) and computable general equilibrium (CGE) modeling. The aim is to come up with a methodological framework for policy design which is both operational and consistent with economic theory. In short this book offers a unified view of this novel approach paying special attention to the connections between economic and environmental objectives. The methodological foundations are presented as well as some real applications that illustrate the pragmatic value of the theoretical proposal.
