Environmental problem recognized
Full cost accounting
Congressperson drafts legislation
Legislation is passed
EPA now translates law into
regulations
Law enforced
Legislative Success!
National Parks
Decreased soil erosion
Some endangered species improving
Decreased pollution
Improved water
quality
Safer drinking
water
Superfund Act
Economics
Study of how we decide to use scarce
resources to provide goods & services
Free market
Supply & demand determine price
U.S. economy
How Are The Economy &
Environment Related?
Environment is the source of materials
Environment serves as a sink for wastes
Sources & sinks contribute to natural
capital
Resource degradation: overuse of
sources
Pollution: overuse of sinks
Economy & Environment
National Income Accounts
Total income in a nation in one year
GDP & NDP provide estimates
Two problems with current system
1) Natural resource depletion
2) Cost & benefits of pollution control
Natural Resource Depletion
Not figured in national income accounts
Oil
Value is part of GDP
Depletion not
subtracted out
Pollution Control
Currently, cost of
polluting not deducted
from GDP
Estimates of
environmental damage
should be subtracted
from GDP
External Costs
Harmful environmental or social cost
Those not directly involved in
transaction
Not reflected
in market price
Market
increases
pollution
How Much Pollution Is
Acceptable?
Pollution is inevitable
Marginal cost
Added cost of pollution
Must balance:
Cost of more pollution
Cost of giving up goods
Marginal Cost Of Pollution
Added cost of pollution
Marginal Cost Of Pollution
Abatement
Added cost of reducing pollution
Optimum Amount Of Pollution
Economically most desirable
Problems?
Economic Strategies For
Pollution Control
Command and control regulations
Limits and punishments
Some success
Problems?
Incentive-based
regulations
Emission targets
Incentives to
reduce emissions
Case Study: Central &
Eastern Europe
Late 1980s: fall of communist
governments
Much environmental destruction
Governments supported heavy industry
Who suffered?
Case Study: Central &
Eastern Europe
Today, environment must be improved
Some areas improving
Some areas recovering slowly: why?
