2I. Economics - Worldviews
- Command Economic System - economic decisions made
by government - Capitalistic System - Market competition between
sellers and buyers brings about the greatest
efficiency of resource use - Pure Market Economy - Philosophy of Adam Smith
- Every individual necessarily labors to render
the annual revenue of the society . for his own
gain, and he is in this, led by an invisible hand
to promote an end which was no part of his
intention. By pursuing his own interest he
frequently promotes that of the society more
effectually than when he really intends to
promote it. - Mixed Market Economy - Gov. control necessary
to fix problems of pure market economy
3- At the end of the 19th Century, the field of
economics divided into two camps - Political Economy was concerned with social
structures, value systems, and relationships
among classes - Neoclassical Economics adapted principles of
science to develop modern economic theory - Retained emphasis on supply and demand in
determining prices and resource allocation - Become dominant guide of 20th Century economics
4- Demand is the amount of a product or service
consumers are willing to buy at various prices - Supply is the quantity of that product being
offered for sale at various prices
5- Two key points in Neoclassical Economics
- Growth is seen as a necessity (a meas. of
vitality) - Natural resources viewed as merely factors of
production rather than critical supplies of
materials, services, and waste sinks
Unimportance of nature
6- II. Problems with pure market economy
- Monopolies / Cartels
- Cycles / Lags (esp. in agriculture)
- Price elasticity (supply/demand not affected by
price) - Providing public goods services (e.g.,
education, police) - Inequitable wealth distribution
- Maintaining public health safety
- Protection of Environment (Sustainability) !
7- How much is clean air worth?
- Can you charge somebody for damaging your air?
- How much are you willing to pay for clean air?
- Should you have to pay for clean air?
8Market Economy promotes environmental damage in
many ways
- Lack of full cost pricing
- Market price includes only internal (direct)
costs - Omits external cost to society future
generations (e.g., contaminating air, water,
resource loss) - Damage to some resources by use of others
(cutting forest gt damage to watershed) - Lack of ownership (responsibility) of some
resources (air, water, ground water) - Lack of ability to correctly cost account for
resource loss - Incorrect method of evaluating economic well-being
9Solving Environ. Problems via the Market a.
Accounting for External Costs
- Internal Costs - Expenses borne by those
marketing a good/service or buying it - External Costs - Expenses born by someone other
than the explicit market participants - Include global warming, ocean pollution, resource
depletion, etc. - Internalizing Costs - Ensuring those that reap
the benefits of resources, labor, capital, etc.
bear all the costs of the use of the resources
10b. Protecting Communal Resources
- Communal Property Resources(Ocean resources,
forests, ground water) - Lack of ownership of resources leads to their
degradation and loss - Tragedy of the Commons Garret Hardin
- Commonly held resources are inevitably degraded
because self-interests of individuals tend to
outweigh public interests
11c. Choosing appropriate Discount Rates
- DR assumes that something is worth less in the
future than it is today - Example A 5 discount rate (DR) predicts a
Future Value of 100 in 20 years is worth 38
today (Net Present Value) Net Present Value
Future Value / (1DR)years - Consider a growing forest stand, in which the
amount of wood will double in 20 years A timber
company could1. Cut the trees and sell them now
(50 each)2. let them grow and increase in value
(100 value in 20 years 38 NPV)
12Normal Discount Rates create a bias against
conservation and undermine efforts towards
sustainability
- High discount rates favor converting natural
resources to human-made capital, since that will
likely yield a higher return - Discount rates undervalue
- intangible resources,
- most natural resources, and
- using resources slowly over time
13d. Market-Based Environmental Protection
- Pollution Charges - Fees assessed per unit of
effluent - Encourages businesses to perform as much
pollution control as possible - Tradable Permits - Allows companies or nations
that can reduce pollution below target levels to
sell their excess capacity
14Market Solutions Pigouvian Taxes
- Taxes on any goods that cause pollution equal to
the cost to society of that pollution - Efficiently raises the price of goods, such that
the amount consumed is reduced to the optimal
level, e.g. tax on gasoline, or tax on carbon - A good way to deal with widespread, multifaceted
issues such as pollution - Government taxation accomplishes two things
- Covers societal costs of pollution (health
effects, land degredation, etc) - Creates incentives for firms to innovate, so as
to reduce tax and increase profits - Becomes part of culture
15- NY Times, Gas Taxes Lesser Evil, Greater Good
- Cheap gas is no longer compatible with a secure
nation, a healthy environment or a healthy
economy - if ever it was. - The real question is whether we should continue
paying the extra dollar or two per gallon in the
form of profits to the Saudis and other
producers, or in the form of taxes to the United
States Treasury, where the money could be used to
build true energy independence. - Gas taxes have been effective in most European
nations - However, taxes are singularly negative in the
U.S., and the most often used from of political
attack
16- Gas or carbon tax
- Reduce greenhouse gas emissions
- Reduce road congestion and accidents
- Encourage exercise walking/biking
- Effective public transit now difficult due to
car-centered development, with highly dispersed
land-use patterns - Better than fuel economy standards, which
- encourage more driving as fuel economy increases
and - fleet level standards basically mean a hybrid
car simply allows car company to produce more
large SUVs, which crush hybrid cars in accident
17Market Solutions Tradable Permits
- Tradable Pollution Permits
- Firms that can lower pollution cheaply, sell
permits - Firms where it is expensive to lower pollution
can buy permits - Drawbacks hot spots can be created (mostly in
rural and low income communities - e.g., current administration proposed marketable
permits for Mercury, which would have allowed
levels to egreatly exceeded those considered safe
18- Tradable Harvest Permits
- Excellent solution for over-harvested fisheries
- Problem Too many commercial anglers chasing too
few fish - e.g., New Zealand fisheries
- Each angler given a Tradable Harvest Permit for X
fish - Low-profit anglers sell their permits and
eventually leave business! - Low cost anglers buy permits and subsidize the
downsizing!
19e. Cost-Benefit Analysis for Economic Decisions
- Attempts to assign values to resources and social
and environmental effects of carrying out any
undertaking - Tries to find optimal efficiency point at which
the marginal cost of pollution control equals the
marginal benefit - Criticisms include absence of standards,
inadequate attention to alternatives, and placing
appropriate monetary values on intangible costs
and benefits
20Fig. 14.21
21f. Jobs and the Environment
- For years, business leaders portrayed
environmental protection as costing jobs (as
opposed to affecting profits) - Ecological economists found only 1 of all
large-scale layoffs in the US in recent years
were due to governmental regulations of any kind - Many aspects of sustainable living promote jobs
- Recycling requires more labor than using virgin
materials
22- Study of four industries (Paper, Plastic,
Petroleum, and Steel) by Morgenstern et al. 2002
JEEM - About 2 of manufacturing jobs lost from all
environ. Issues - However, nationally, the average gross job effect
is a net gain of 1.5 jobs per 1 million in
additional abatement spending - A jobs transfer instead of jobs lost due to
environmental regulation!

24Biggest Negative toward sustainable economy is
using GDP for evaluating Economic Well-being !
- Even worse is that we use Growth in GDP
- GDP (Gross Domestic Product) is total value of
all economic activity in a nation for a year - It is a very poor way to evaluate true Economic
Well-being - Growth in GDP promotes environmental damage, poor
health, and population growth
25Problems with GDP
- Does not distinguish between beneficial and
harmful growth - Does not account for resource depletion or
ecosystem damage - Most negatives are added to GDP (? cost of ill
health gt ? GDP !)Pollution is a triple
negative Higher Corp. profit Value from
cleanup Value of neg. health effects - Underestimates environmental / social positives
(e.g., energy efficiency, good health,
sustainability))
26- Growth in GDP overestimates society well being
- 1950-2000 GDP ? 170 But Wages ? 14 Oil
reserves ? 40 - Alternatives to GDP
- Index of Sustainable Economic Welfare (ISEW)
- Genuine Progress Indicator (GPI)
- Takes into account real per capita income,
distributional equity, natural resource
depletion, environmental damage, etc. - GPI increased 60 from 1950 to 1970, but has
remained unchanged since then
27Fig. 14.22
28Growth in GDP vs. population growth
29A New Economic Philosophy is Needed !
- Too much and too long, we have surrendered
community excellence and community values in the
mere accumulation of material things. - Our gross national product - if we should
judge America by that - counts air pollution and
cigarette advertising and ambulances to clear our
highways of carnage. It counts the destruction of
our redwoods and the loss of our natural wonders
in chaotic sprawl - Yet the gross national product does not allow
for the health of our children, the quality of
their education, or the joy of their play. It
measures neither our wit nor our courage neither
our wisdom nor our learning neither our
compassion nor our devotion to our country. - It measures everything, in short, except that
which makes life worthwhile.
Robert F. Kennedy Address, University of Kansas,
March 18, 1968 3 months before he was assassinated
30III. Sustainable Economiesa. Ecological
Economics
- Acknowledges dependence on essential life-support
services provided by nature - Regards some aspects of nature as irreplaceable
and essential - Sustainable economy is characterized by, use of
renewable energy sources, material recycling, and
emphasis on efficiency, stability, and true
measures of economic well being
31Prevailing economic philosophy treats Natural
Resources as equivalent to all others
- Types of Economic Capital
- Natural
- Manufactured
- Human (Labor, Entrepreneurial)
- Social (Education, Health, Safety)
- Capital is a resource converted to human use and
available to produce more wealth - Prevailing philosophy assumes complete resource
inter-substitutability
32- Debate over value / substitutability of Natural
Resources - Economically recoverable reserves are not rigidly
fixed - Human ingenuity and technology often allow us to
respond to scarcity in ways that alleviate
predicted effects - Technological developments led to price declines
for most raw materials during the industrial
revolution - Economists generally believe this pattern will
continue, while Ecologists disagree(so far,
economists have been right!)
33(No Transcript)
34- However, Natural Resources are not equivalent!
- Nonrenewable resources - Materials present in
fixed amounts in the environment (e.g., metals,
fossil fuels, some ground water) - Renewable resources - Materials that can be
replenished or replaced (e.g., water, forest
products, food) - Intangible resources - Abstract resources such as
open space, beauty, areas for solitude etc.
35Viewpoint 2 The world will run out of oil
36Prevailing Economic System
- Private ownership of material resources
- Public ownership of sinks
- Perfect functioning of the market
- Infinite substitutability of resources
- Subsidized disposal, energy, water
37In prevailing economies the Ecosystem is seen as
a sector of the Economy Mostly serves as
subsidized source of resources sink for wastes
Economy
Ecosystem
38Ecological Economics considers human economic
systems to be part of natural ecosystems
39Summary of Current vs. Ecological Economics
- Current economic system
- Depends on the scale of material/energy
throughput - Subsidizes resource extraction and pollution
- Taxes productive activities
- Does not measure welfare
- A system based on Ecological Economics would
- Shift taxes to waste, inefficiency, and pollution
away from wages, productivity, and
investment - Focus on dematerialization, energy efficiency,
decarbonization, and waste reduction - Measure true welfare instead of absolute monetary
transactions material gain - Support an Sustainability Revolution
40b. Sustainable Living
- Involves educated citizenry and leadership at
local, national and global levels - Starts with individuals acting to protect their
own health and that of their local environment - Individuals can chose to support environmentally
sustainable businesses - Our leaders must eliminate subsidies to
environmentally destructive businesses and
activities - The global community must act in the interest of
protecting the Earth and the well being of all
peoples
41- The economy responds to signals it is sent
- Cheap waste disposal
- Low costs for emissions (air, water, land)
- Low cost for environmental impacts
- Cheap and subsidized resources
- Tax benefits for resource depletion
- We need to send new signals!
- Recognizing the value of Nature
- Change from consumption-driven economy
- Supporting green businesses
- Leaders with vision to challenge status quo

44Supporting Green Business
- Consumers support Businesses that recognize that
raw materials are not inexhaustible that
maintain the highest standards for worker health
and benefits - Businesses operate in a socially responsible
manner that is consistent with principles of
sustainable development - Good for business consumers
- E.g., pollution from inefficiency waste lower
profits
45- Green businesses -)
- Newmans Own 100 organic profits to Earth
sustaining activites - 3 M Company reducing resource use and reusing
and recycling resources - BioShield makes environ. friendly paints,
thinners, - Canon global recycling taken action for
reducing global warming - Kinkos many programs to reduce paper
consumption - American Apparel no sweat shops! favorable
worker health conditions - Patagonia Clothing organic cotton! support
worker health / environ. causes - Esperanze Threads organic cotton!
- Aveda Cosmetics Body Products environmentally
friendly products - Burts Bees Body Products use natural
ingredients - REI donates profits to conservation, using
renewable energy - Ikea eliminated plastics, and reduced waste in
furniture manufacture - Johnson Johnson - has cut air and water
pollutants dramatically - Trader Joes organic foods renewable energy
support
46- Black Businesses (
- Mitsubishi - most environmentally destructive
corporation ever!!! - Clearcutting of tropical forests in Indonesia
- Clearcutting of tropical forests in Ecuador
- Dumping of radioactive wastes in Malaysia
- Dumping of toxic wastes and acids in Mexico the
Ocean - Walmart business practices encourge
externalizing costs - Exxon-Mobil huge amts of pollution,
environmental exploitation, legislative lobbying - Also Chevron, Pemex
- DOW huge amounts of pollution, health worker
safety - Arthur Daniels Midland massive agricultural
impacts (chemicals, fertilizers, etc) - Boise-Cascade Paper products derived from
deforestation in Cent S. America - Kimberly-Clarke (Kleenex other paper products)
massive forest clearcutting - Ford Motor Co. lobbying for polluting vehicles,
leading user of "Maquiladoras" - (Most other auto companies, as well)
- Nike / Reebok sweat shops with heinous working
conditions and very low wages - Abercombie Fitch sweat shops, deceptive
labeling (says made in USA, but not) - GAP Clothing sweatshops with low wages and poor
working conditions
47World Economic Issues
- According to economic theory, each place has
goods or services it can supply in better
quality, or at better prices, than its neighbors - Basically, this keeps less-developed countries in
a perpetual role of resource suppliers to
more-developed countries - General Agreement on Trade and Tariffs has played
a hugely negative role in promoting
environmentally destructive practices - World Trade Organization (part of GATT) has never
to my knowledge ruled in favor of the
environment! - World Bank - a consortium of banks from developed
countries looking to exploit cheap labor and lack
of environ. regulations in developing countries
48Trade Development
- According to economic theory and comparative
advantage, each place has goods or services it
can supply in better quality, or at better
prices, than its neighbors - In practice, however, most trade keeps
less-developed countries in a perpetual role of
suppliers of resources and cheap labor to
more-developed countries - Many lending practices also promote this
inequality (IMF, World Bank)
49Fig. 14.5
50Micro-lending
- Small loans to individuals families promote
local economies
- Mohammad Yunus and Grameen Bank shared the 2006
Nobel Peace Prize - Grameen now has 6 million borrowers worldwide
51What is a Maquiladora?
- Maquiladoras originated as part of Mexican
governments Border Industrialization Program
(1965) - Maquiladoras are foreign-owned manufacturing
plants that process or assemble imported
components for export - Maquiladoras account for 49 of Mexicos exports
Maquiladoras employ mostly women aged 18-25 for
its labor force
52Examples Maquiladoras in Mexico
- Bali Company
- Bayer / Medsep
- BMW
- Casio
- Chrysler
- Eastman Kodak / Verbatim

56- Enormous amounts of toxins used in maquiladoras
- Majority of workers are not provided with the
necessary education or protection concerning
the chemicals they are exposed to on a daily
basis
57Lets end on a bright note!
