This book outlines the roles of environmental policy analysis in design and evaluation of a wide range of environmental policies. The book emphasizes methods and tools for performing policy analysis such as benefit-cost analysis as well as supporting tools such as non-market valuation (travel cost method, contingent valuation and hedonic pricing), input-output models, linear regression techniques, and linear programming/optimization models. Numerous real world examples illustrate how the techniques have been applied in actual policy analyses.
