Economics and the Environment
Economic theory explains what we observe in reality
Microeconomic analysis can also be used to analyze environmental problems

Economics and the Environment
Circular Flow Model – the basis for modeling the relationship between economic activity and the environment Real Flow Factor Market Output Market Money Flow
Does not explicitly show the linkage between economic activity and the environment

Economics and the Environment Materials Balance Model – illustrates the
relationship between economic activity and the environment Flow of Resources
Natural Resource Economics – concerned with flows of resources from nature to economic activity
Flow of Residuals Residuals – by-products released back into the environment Assimilative Capacity – environmental ability to absorb
residuals Recovery Recycling and Reuse – methods to delay the flow
of residuals

Economics and the Environment
Materials Balance Model Science and Materials Balance
First Law of Thermodynamics – matter and energy can neither be created nor destroyed
Second Law of Thermodynamics – nature’s capacity to convert matter and energy is not without bound

Fundamental Concepts in Environmental Economics Causes of Environmental Damage: Types of
Pollutants Natural Pollutants – nonartificial Anthropogenic Pollutants – human induced and
include all residuals associated with consumption and production
Of greater concern to environmental economists

Fundamental Concepts in Environmental Economics Sources of Pollution: Classifying Polluting
Sources Source Grouped by Mobility
Stationary Sources – fixed site Mobile Source – any non-stationary source
Sources Grouped by Identifiability Point source – single identifiable source Nonpoint Source – a source that cannot be
accurately identified

Fundamental Concepts in Environmental Economics Identifying the Scope of Environmental
Damage: Local, Regional, and Global Pollution Global Pollution – widespread environmental effects
with global implications Examples:
• Global warming• Ozone depletion

Identifying Environmental Objectives
Environmental Quality – reduction in anthropogenic contamination to socially acceptable levels
Sustainable Development – management of resources to ensure long-term quality and abundance
Biodiversity – the variety of distinct species, genetic variability, and variety of inhabitable ecosystems

Environmental Policy Planning: An Overview
National Environmental Policy Act Risk Analysis
Risk Assessment – qualitative and quantitative evaluation of risk posed by an environmental hazard
Risk Management – decision process of choosing from alternative responses to environmental risk
![Page 15: Environmental Economics and Management: Theory, Policy, and Applications 3e by Scott Callan and Janet Thomas © 2004 Thomson Learning/South-Western.](https://reader035.fdocuments.net/reader035/viewer/2022062216/56649d2b5503460f94a000e9/html5/thumbnails/15.jpg)

Environmental Policy Planning: An Overview
Policy Evaluation Criteria Allocative Efficiency – requires resources be
appropriated such that benefits are equal to costs Cost-effectiveness – requires the least amount of
resources be used to achieve an objective Environmental Quality – concerned with the fairness
of the environmental risk burden across segments of society or geographic region
![Page 16: Environmental Economics and Management: Theory, Policy, and Applications 3e by Scott Callan and Janet Thomas © 2004 Thomson Learning/South-Western.](https://reader035.fdocuments.net/reader035/viewer/2022062216/56649d2b5503460f94a000e9/html5/thumbnails/16.jpg)

Environmental Policy Planning: An Overview
Government’s Overall Policy Approach Command-and-control Approach – regulates polluters
through the use of rules Market Approach – incentive policy that encourages
conservation or pollution reduction “Polluter-pays Principle” – polluter pays for the damage
caused
Setting the Time Horizon Management Strategies – a short-term strategy intended to
manage an existing problem Pollution prevention – long-term strategy aimed at
reducing the amount of toxicity of residuals released to nature
