Issues: Air Pollution Ground Level Ozone (O 3 ) Nitrogen Oxides (NOx) Particulate Matter (PM, TSP) Sulphur Oxides (SOx) Volatile Organic Compounds (VOCs) Carbon Monoxide (CO)
Ozone: 11 AM, Bay&Wellesley
Ozone: Monthly Averages
NOx: 11 AM Bay&Wellesley
NO2: Monthly Averages
TSP: Bay&Wellesley
TSP: Monthly Averages
SO 2 : Bay&Wellesley

Air Pollution vs Income Is it like this?
Air Pollution vs Income
Air Pollution Since 1940: USA
Air Pollution vs Income: USA
Water Pollution (Kg/worker/day) vs Income
Water Pollution: Great Lakes
Global Issues: Ozone Layer
Instruments Standards Emission Standards Technology Standards Emission Charges (Taxes) Tradable Emission Permits Tort Law
Standards E.g. US motor vehicle emission standards
Tradable Emission Permits E.g. US EPA SO 2 Allowance Market
Tradable Emission Permits Number of trades
Institutions Canada Federal Government Inland waterways, CCME, International Treaties, Environmental Assessment, Motor vehicles, Endangered Species, Toxic Substances Provincial Government Air and water contaminant regulation, Energy, Municipal oversight (e.g. solid waste management) Courts Tort law, property rights
Models of Economic Growth and the Environment Substitution Effect: Growth uses up natural assets Income Effect: Expands resources for environmental protection
Models of Economic Growth and the Environment Output constraints
Models of Economic Growth and the Environment Preferences
Models of Economic Growth and the Environment Combining:
Environmental Kuznets Curve Low income: pollution rises as income rises High income: pollution falls as income rises
Beltratti Model Utility Function Production Function Environmental Quality Capital Stock
Beltratti Model Environment deteriorates according to
Beltratti Model Simple structure, yet: Has no steady state Can generate any relationship between pollution and income U, ∩, ~, etc. Bottom line: growth theory unlikely to make one single prediction about pollution v growth, but might help explain different histories
