Appendix : Key Features of U.S. Sky Trust
Here are the key features of the proposed U.S. Sky Trust.
o Carbon emissions cap set initially at 1.346 billion tons, the 1990 level
o Tradable carbon emission permits sold annually to energy companies at the top
of the carbon chain.
o All revenue from permit sales goes into a nationwide trust.
o Trust pays equal annual dividends to all U.S. citizens (like the Alaska Permanent
Fund).
o Dividends can be placed tax-free in Individual Retirement Accounts or Individual
Development Accounts for children.
o Initial price ceiling on carbon emission permits of $25 a ton; ceiling rises 7
percent a year for four years.
o Transition Fund to help those most adversely affected by higher carbon prices.
Fund starts at 25 percent of permit revenue, declines 2.5 percent per year.

possible.”
-Milton Friedman 1962
BIAYA REGULASI
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”

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!

Non-rival,

Market Good:
Food, clothes, cars, land,
timber, fish once captured,
farmed fish, regulated
pollution
Potential market good
(Tragedy of the “noncommons”)but inefficient:
patented information,
Pond, roads (congestible),
streetlights
Private beaches, private
gardens, toll roads, zoos, movies
Non-Excludable
Open Access Regime: (misnamed:
Tragedy of the commons)
Oceanic fisheries, timber
etc. from unprotected
forests, air pollution, waste
absorption capacity
Pure Public Good:
climate stability, ozone layer,
clean air/water/land,
Biodiversity, information,
habitat, life support functions,
etc.
Public beaches, gardens, roads,
etc.
