Autism, a disorder characterized by:
• Absorption in self-centered subjective
mental activity (such as daydreams,
fantasies, delusions, and hallucinations)

Pareto Efficiency
When no one can be made better
off without harming someone else
Fundamental Theorems of
Welfare Economics
1. Pareto Efficiency implied by:
a. Maximization of consumer preferences
under budget constraints.
b. Maximization of profits under technology
constraints.
2. Any Pareto Efficient outcome can be
supported with lump sum transfers.
Policy Implications

Pillars of the First Theorem
1. A theory of human behavior based on an
isolated, rational, self-maximizing
individual at a point in time
2. A theory of firm behavior based on
perfect competition, production as
allocating fixed resources, and
exogeneous technical change
The Efficiency Criterion requires we:
• Ignore interpersonal, intergenerational,
and interspecies comparisons
• Accept the rational actor model of human
behavior
• Accept perfect competition
• Accept an economic system devoted to
material production, free of social and
biophysical constraints
The Ecological Economics Umbrella
• Human economy as a social system
embedded in a biophysical universe
• Efficiency as a third-tier goal, behind
sustainable scale and equitable
distribution
• Allocation of scarce means among
alternative desirable ends
