Economies as Evolutionary Systems
Hunter gatherer economies (Pleistocene)
“Limited wants, unlimited means”
Accumulation = death
Agricultural economies (Holocene)
Property rights, division of labor, political hierarchy
Population density, knowledge, and rate of change
Industrial economics (Dawn of Anthropocene)
Fossil fuels, non-renewables
Competitive self-interest, capitalism and growth
Great acceleration (population etc., 1950 on)
Economies as Evolutionary Systems
Financial economics (now)
Profound change in our lifetimes
Price from negative to positive feedback loops
From growth to unequitable redistribution
Information economy and Ecological Economy (emerging)
Degrowth and equitable distribution (contraction and
convergence) essential
Cooperation and altruism necessary and more efficient
Economy as a physical system:
Laws of Physics
Can’t make something from
nothing or vice versa
Can’t do work without energy
Disorder increases
Laws of ecology
Conversion of ecosystem structure into economic
products degrades and destroys ecosystem functions
e.g. water purification, habitat
Waste emissions degrade and destroy ecosystem
services e.g. climate stability
Laws of Economics
• When marginal
costs exceed
marginal benefits,
stop
• 4x increase in
population, 9x
increase in per
capita consumption
in 100 years
• Uneconomic growth
Societal Challenges on a Finite Planet
Planetary Boundaries
Social Foundations
demands just and sustainable degrowth
Marginal value (cost)
Ecological thresholds and the
economic supply curve
Must sum together all costs: labor,
capital, biodiversity loss, nitrogen,
climate change, etc.
(marginal cost)
Degrowth
essential
Economic output (fossil fuel economy)
Trade-offs: Life
sustaining
benefits
Value:
Increasing
rapidly with
decreasing
quantity.
Trade-offs:
Resilience,
increasingly
important
benefits
food security, household security
Value: shift from
marginal to total
value (e.g.
diamond-water
paradox)
physiological threshold: e.g. starvation
Marginal value (benefit)
Physiological boundaries/thresholds and the
demand curve
Value: low and stable
Trade-offs: relatively
unimportant benefits
Essential resources (social foundation), e.g. calories/day
Societal Challenges on a Finite Planet
Market Solutions
Competition, self-interest and choice
Preference satisfaction
Internalize externalities
Make prices reflect full costs
Creates incentives for innovation and substitution
Preferences weighted by purchasing power
Americans spend 6% of income on food for home consumption;
~1% on raw food
Many Africans spend 75%; ~ 50% on raw food
What happens when prices double?
Preferences prioritized over physiological need
Middle class
food security, household security
Price
Rich
physiological threshold: e.g. starvation
Market Demand curve for essential resources
Poor
Food production (in calories/day/capita)
Markets in Action
Marginal market costs
(Market supply curve)
Ignore
ecological
costs
Ignore needs of the
poor
Why markets fail
Non-excludability (ecosystems)
Lack of laws and institutions, e.g. oceanic fisheries, waste
absorption capacity, population
Inherently non-excludable, e.g. climate regulation,
protection from storm surges, etc.
Only collective ownership is possible
Non-rivalry (e.g. information and green technology)
Physical characteristic
Resources not depleted through use; prices create artificial
scarcity
Optimal price is zero
Collective provision with no ownership is optimal
Why markets fail
Essential Resources
Demand insensitive to price
Gross inequality
Preferences of the rich trump needs of the poor
Prisoner’s Dilemmas
Global Climate Change
Population growth
Natural resource depletion/biodiversity loss
(finite raw material sources, finite services)
Innovation in the information age
E.g. green technology
Cooperation is best solution
Collective ownership
Collective production/protection
Can People Cooperate?
Stupid question?
Are people good or evil?
Characteristics of an evil person
Characteristics of a good person
Evolution of Cooperation
Genetic
Multi-level selection
Distribution of pro-social behavior
Good person puts group ahead of individual
Bacteria, slime-molds, social insects, humans (super cooperators)
Oxytocin
Cultural
Altruistic punishment (public good game; ultimatum game)
Punishing non-punishers
Group identity
Reciprocity and indirect reciprocity
Economics of Cooperation
Alternative energy, sustainable food system technologies
Values maximized at price of zero
Competitive markets create scarcity (production and
consumption)
“Energy transitions produce cultural transitions”
Myxococcus xanthus, Dictyostelium discoideum and the
human predicament
“Struggle for energy causes violent conflict”
Cooperation for energy ends violent conflict
Institutions for Cooperation
Institutions can make generous people act
selfishly, or selfish people act generously
Economics, money and cooperation

Reciprocity, altruistic punishment, social
norms
Intrinsic vs. extrinsic motivation
From Markets to Commons
Essential ecosystem functions cannot be made into
private property
Collective decision making, protection is necessary
No one owns waste absorption capacity
Green technologies should not be private property
Collective provision, open access is most efficient
Unilateral action is possible
Redefining the group
Altruistic behavior towards group
Monitoring and enforcement: altruistic punishment
Changing Complex Systems
Change the paradigm
What is biophysically possible
Human nature
Change the goals
From growth and maximizing monetary value to
sustainability, justice and basic needs
Change the rules/institutions
Depends on what is possible and desirable
Based on science, not ideology
Conclusions
Markets emerged simultaneously with fossil fuels
Nature of ‘scarce’ resources has changed from rival,
excludable to non-rival and/or non-excludable
Cannot transform physical characteristics of resources to
fit market model
Must transform economic system to resource
characteristics, human behavior
Prisoner’s dilemmas
Physiological necessities
Cooperation and common ownership for most pressing
problems
Naïve and utopian?
