Intro to Ecological Economics
DEFINE TERMS
1) SCALE-Size of the economy in relation to the biosphere (macro-economics)
2) DISTRIBUTION-Apportionment of income and wealth among different individuals
3) ALLOCATION-Apportionment of resources to production of different goods and services
4) CONSILIENCE, (EO WILSON)-Theories must be consistent with other sciences

NEO-CLASSICAL ECONOMICS 1890-
No Ingredients, only labor and capital
P = f(L,K)= ALa . BKb (Cobb-Douglas multiplication)
Labor (Chef )
Capital (Mixing bowl)

Quotable Quotes
• “There is no reason we can’t have a perfectly healthy economy with virtually no resources whatsoever” Robert Solow
• “We can do without agriculture because it’s only 2% of the economy.”Norgaard?
• “neo-classical economics is a form of brain damage” -- Hazel Henderson

ALLOCATION
PARETO EFFICIENCY:
“No other allocation of resources would make someone better off without making someone else worse off.”
Rivalness and Excludability• rival
– My use leaves less for you to use
• Excludable (property rights)– One person can keep another from
using the good– Consumer must pay, market will
supply
Must have a price to work in the free market!
Rivalness and Excludability• Non-rival
– My use does not leave less for you to use
– Market sells for a price, discouraging use, but social cost of use = 0, therefore market should not supply
• Non-excludable– One person can’t keep another from
using the good– Consumer will not pay, market will
not supply
Must have a price to work in the free market!
Rival}
Non-rival}
Excludable Non-Excludable
Market Good: Food, clothes, cars, land, timber, fish once captured, farmed fish, regulated pollution
Potential market good(Tragedy of the “non-commons”)but inefficient: patented information,Pond, roads (congestible),streetlights
Pure Public Good:climate stability, ozone layer, clean air/water/land, Biodiversity, information, habitat, life support functions, etc.
Open Access Regime: (misnamed: Tragedy of the commons)Oceanic fisheries, timberetc. from unprotected forests, air pollution, waste absorption capacity
Non-rival,congestible
Private beaches, private gardens, toll roads, zoos, movies
Public beaches, gardens, roads, etc.
“Maximization of Shareholder Value”
“Golden Rule of Publicly held companies:
Rational behavior:
Externalize costs
Influence politics to
Seek subsidies and favors
“Invisible boot”
“Altruism is evil and selfishness is a virtue.” -Ayn Rand
Quotable Quotes
“Few trends could so thoroughly undermine the very foundations of our free society as the acceptance by corporate officials of a social responsibility other than to make as much money for their stockholders as possible.”-Milton Friedman 1962
Enron, World Com, Tyco????
Cost of regulations-OMB report
Annual Cost: $37-43 billion
EPA conservative approach, Consistently overestimates costs, not considering least cost approach and technical innovation
Annual Benefits: $121-193
EPA consistently underestimates benefits
USING ACTUAL NOT THEORETICAL CASES BENEFITS OUTWEIGH COSTS 5:1
CONSILIENCE
“~Resources are infinite and the economy can grow forever” -Julian Simon
“Anyone who thinks you can have infinite growth on a finite planet is either a madman or an economist” Kenneth Boulding
