Trang 1517-2 How Can We Use Economic Tools to Deal with Environmental Problems?
Concept 17-2A Using resources sustainably will
require including the harmful environmental and health costs of resource use in the market
prices of goods and services (full-cost pricing)
Concept 17-2B Governments can help improve
and sustain environmental quality by
subsidizing environmentally beneficial activities and by taxing pollution and wastes instead of
wages and profits.
Trang 16External Costs
Market price leaves out environmental and
health costs associated with its production
Goods and services include external costs
Excluding external costs
services
Trang 17Use of Environmental Economic
Indicators

measure environmental degradation

Environmentally honest market system makes
sense
Not widely used
of business
• Difficult to estimate environmental costs
environmental costs with purchases
Government action needed

Businesses
Encourage shifts

• $2,500 per year in harmful subsidies
• Additional health costs
Trang 23Environmental Taxes and Fees

Trang 24Tax Pollution and Waste
Green taxes discourage pollution and waste
Current tax system
• Discourages jobs and profit-driven innovation
• Encourages pollution, resource waste,
degradation
Tax shift towards green taxes needed
