A substantial revision of a comprehensive, accessible introduction. Over 50 percent of the material is entirely new, and the text features particularly strong and extensive treatment of welfare economics and market failure concepts, project evaluation, investment theory, land markets and allocation of exhaustible and biological resources, and environmental quality issues. A unique policy orientation links economic theory with the ``real world'' of interest-group politics. This new edition introduces the concepts of scarcity and growth with in-depth definitions of resource types and a more rigorous treatment of project evaluation.
