Chapter 23 Economics, Environment, and Sustainability
2
New Economic and Environmental Vision Ecological Economists - Redesign economic and political systems Environmental Economists - Reform of current economic systems rather than redesign Sustainability revolution=economic revolution
3
ECONOMIC SYSTEMS An economic system produces and distributes goods and services by using natural, human, and manufactured resources.
4
Economic Systems Are Supported by Three Types of Resources Natural Resources-goods and services produced by the earth’s natural processes Human Resources-people’s physical and mental talents that provide labor, innovation, culture, and organization Manufactured Resources-machinery, equipment, and factories, which are made from natural resources with the help of human resources
5
Three Types of Resources Are Used to Produce Goods and Services
6
Market Economic Systems Pure Free-market economic system –Theoretical model in which buyers and sellers interact in markets without any gov’t interference. –Pure free markets do not exist in today’s capitalist market system Companies lobby for gov’t subsidies, tax breaks, or regulations to get advantages $ 1 trillion in gov’t subsidies given out each year.
7
Supply and Demand Supply-the amount of a good that is available Demand-The amount of a good that people want Price-market cost of a good or service Profit or loss-the difference between the cost of producing something and the price buyers are willing to pay
9
Government Intervention in Market Economic Systems Governments intervene in market systems to help provide economic stability, national security, and public services such as education, crime protection, and environmental protection.
10
Problems with Capitalist market system Do not make widespread use of indicators that monitor environmental health and quality Do not include the harmful environmental costs of goods in their market prices. Do not consider long-term harmful environmental consequences because the focus is on short term profits
11
Environmentally Sustainable Economic Development: Copying Nature Models of ecological economists are based on these assumptions: –Resources are limited. –Encourage environmentally beneficial and sustainable forms of development. –The harmful environmental and health effects of producing goods and services should be included in market prices.
12
We Can Estimate Optimum Levels of Pollution Control and Resource Use Relationship between –Marginal benefit of resource use –Marginal cost of resource production Optimum level of resource use Optimum level for pollution cleanup
13
Marginal Cost/Benefit Marginal Cost-the additional cost of producing one more unit of a good or service. -The difference between a seller’s starting price and the new price Marginal Benefit-The increase in benefit that it provides to the buyer when one more unit of a good or service is produced.
14
–Mitigation cost: how much it takes to offset any environmental damage. –Willingness to pay: determine how much people are willing to pay to keep the environment in tact (e.g. protect an endangered species).
15
Optimum Pollution Control
16
Cost-benefit Analysis Making economic decisions about how to control pollution and manage resources Estimate optimum level of pollution cleanup or resource use Estimating costs for –Pollution control regulation –Building a dam on a river –Preserving an area of forest
17
Economic Indicators GDP and per capita GDP –Provide a standardized and useful method for measuring and comparing the economic outputs of nations –Doesn’t determine between the good that are environmentally or socially beneficial or harmful –New ideas Add to the GDP items concerning environmental quality Subtract from GDP cost that lead to lower quality of life/ degrade natural resources
18
GPI GPI- Genuine Progress Indicator –Estimated values of beneficial transactions that meet basic needs, but in which no money changes hands, are added to the GDP. Unpaid volunteer work, health care, childcare, housework GPI= GDP+ benefits not included in transactions - harmful environmental and social costs
19
Monitoring Environmental Progress: Comparing Per Capita GDP and GPI
20
Estimating Future Value of a Resource Economists use discount rates (estimate resource’s future value compared to current) to estimate the future value of a resource. The market price you pay for something does not include most of the environmental, health, and other harmful costs associated with its production and use. (Full Cost Pricing)
21
Full Cost Pricing Environmentally honest market system –Way to deal with the harmful costs of goods and services –External Costs are health and environmental costs, not usually included in market price –Harmful indirect or external costs of goods or services in their market prices to reflect as close as possible to Full costs Full Cost= internal costs+ external costs
22
Full-Cost Pricing Marketed price of a good or service includes the cost to make the good or produce the service, plus the harmful indirect cost, including health and environmental effects Encourages producers to become more resource efficient and produce less pollution
23
Objections Producers would have to charge more for their goods. They might go out of business It is hard to put a price tag on environmental and health costs
24
Product Eco-labeling Encouragement to develop green product US Green Seal –Easy for consumers to buy these products
25
Subsidies Phase out environmentally harmful subsidies and tax breaks. They create huge economic incentive for unsustainable resource depletion –Extracting minerals –Cutting timber on public lands –Supplying fertilizers –Low cost water for farmers
26
Subsidies Typical American taxpayer pays at least $2500 a year to provide environmentally harmful subsidies and then pays $1000 due to environmental degradation, pollution cleanup, and higher health and insurance costs
27
Subsidy Shifting Phase in environmentally beneficial subsidies and tax breaks –High subsidies for Energy conservations Renewable energy Sustainable forestry Sustainable agriculture Soil and water conservation Etc.
28
Subsidy Shifting in Other Countries Japan, France, and Belgium have phased out all coal subsidies Germany plans to do so by 2018 China has cut coal subsidies by nearly 73% New Zealand has phased out virtually all agricultural subsidies
29
Objection Organizations currently receiving subsidies lobby to resist change
30
Taxes Encourages- what we want less of –Pollution, resources waste Discourages- what we want more of –jobs, income
31
Green Taxes Tax amount of pollution and hazardous waste produced. Tax use of fossil fuels, nitrogen fertilizer, timber, minerals etc.
32
Tax Shifting Reduce tax on profits and income = Good Tax pollution, overuse of resources = Bad In Europe, green tax = 7% of total tax revenue In Denmark, tax on a new car is more than price of the car
33
3 requirements for Green Taxes 1. 15 to 20 years to phase in 2. mechanism to ensure that the revenues from such taxes improve environmental quality/reduce taxes on labor, income and wealth 3. Poor and lower class need an economic safety net- reduce regressive nature of taxes
34
Selling Services Material flow economy -> service flow economy –Customers can ecolease or rent services that good provide –Document services- leasing a photocopier (XEROX) –Chemical services- leasing organic solvents –Mobility services- lease a vehicle
35
Worldwide Poverty Poverty: the inability to meet one’s basic economic needs 1.1 billion people struggle to survive on less than $1 a day About half the world’s population live on a daily income of $1-2
36
Solutions: Reducing Poverty Cancel debts of poorest countries Mount global effort to combat malnutrition and infectious diseases Provide universal primary school education and eradicate illiteracy Stabilize population growth in developing countries Microloans
37
Grameen Bank in Bangladesh Lending $50-$500 at a time instead of large amounts Solidarity groups of 5 Less than 3% of payments are late About half of those borrowing money have escaped poverty within 5 years
38
Microloans Muhammad Yunus won Nobel Peace Prize in 2006 Citibank and TIAA-Cref have each committed $100 million to microloans
