This course focuses on how basic economic concepts — supply, demand, and opportunity cost — can be used to understand and manage a wide range of environmental problems. Topics include the sources of market failure for environmental goods, externalities and policy approaches for their control, discounting and benefit-cost analysis, nonmarket valuation, and management of nonrenewable and renewable resources. The emphasis is on conceptual understanding rather than formulas or solution algorithms; students have to understand economic reasoning more than they will use math. The tests and much of the homework assignments are short-answer questions that require students to explain their reasoning. Lectures will cover key concepts; discussion sections and readings will provide reinforcement through examples and problem-solving. Students completing this course will have an improved understanding of the economics paradigm, the sources of environmental problems, and some ideas for their solution.
