5
Main problems with current economic theory
  • Externalities
  • - costs not borne by those who create them

Badly defined property rights - environmental
goods perceived as commons
The environment is not subject of rights - the
environments interests are not legally
represented in the economic system
6
Internalization
  • London Congestion Charge
  • 5 daily for driving or parking a vehicle on
    public roads within the congestion charging zone
    between 0700 and 1830, Mon to Fri
  • Goals
  • reduce congestion
  • improve bus services
  • improve journey reliability for car users
  • make the distribution of goods and services more
    reliable, sustainable and efficient

Commodity system challenges
  • What are commodities?
  • What forces drive the commodity markets?
  • What are the challenges of the CS?
  • How to neutralise them?

9
What are commodities?
  • Raw material or only little processed item
  • Traded product
  • Uniform characteristics everywhere the same
  • Standardization and substitutability
  • Choice based on price since all are the same

10
Commodity systems
  • Mono-culture Few similar, specialized
    large-scale producers sell internationally
  • Huge production increases Large price
    decreases

3 commodity systems traps !
Trap Easy to fall in, Hard to get out
17
Evidence of trap 1 resource depletion
18
Resource depletion trap

Regeneration rate
Harvest
Rate


Resource level
-
19
Often when supply seems plentiful
Over-harvest
20
Resource depletion trap WHY?
  • Harvest capacity overgrows
  • passes sustainable yield ? overshoot
  • Market signals of scarcity (prices are said to
    reflect scarcity, arent they?)
  • too weak, too delayed
  • Endgame tactics
  • final desperate efficiency boosts ? harvest
    increase as resource disappears

21
  • Socialism collapsed because it did not allow
    prices to tell the economic truth.
  • Capitalism may collapse because it does not
    allow prices to tell the ecological truth.

Source Dahle, 2001.
22
Resource depletion trap HOW TO ESCAPE?
  • Better information feedbacks
  • Link health of resource with change (increase or
    decrease) in harvest capacity
  • Research to accurately know rates of harvest and
    resource regeneration
  • Better control of capacity
  • Rates of harvest and death never exceed
    regeneration rate

23
Environmental pollution trap
-
Waste level
-

Waste generation
Purification rate
24
All production is joint production !
Implied by the First and the Second Laws of
thermodynamics
  • permits to depict externalities related to
    production
  • solid foundation for the precautionary principle

26
Where do the problems come from?
  • Strength tight information focus
  • Narrow focus down to volume and cost makes system
    lean and efficient
  • Weakness ignorant of long term trends
  • Lack of feedback blinds us to signs of pollution,
    resource depletion, community decline
  • Similar situation in most types of markets

27
How to escape the commodity traps?
  • Market products outside the system
  • High quality products recognized as unique by
    where and how produced
  • Restructure the system
  • Change rules, incentives and penalties to balance
    productive capacity with environmental and social
    goals

28
How to escape? More detailed strategies
  • Collective agreement to limit harvest intensity
  • Producers agree on a new set of rules ?
    individual rational choices add up to sustainable
    harvest
  • Agreements to limit price supports and supply
  • Producers give up the right to produce any amount
    in return for guaranteed minimum prices
  • Certification programs
  • Bring environmental and social goals into the
    system

29
Certification of organic farming

30
Certification ? fair trade coffee
  • price covers the cost of production
  • social premium for development purposes
  • partial payment in advance to avoid small
    producer organizations falling into debt
  • contracts that allow long term production
    planning and sustainable production practices
  • decent wages, good housing, minimum health and
    safety standards, right to unionize, no child or
    forced labor
  • minimum environmental requirements

31
Success ? surviving global price gyrations
Fair trade producers never fall below critical
minimum price
Price drops force many other producers
out. Result starvation in Central America
32
But... certification is only a partial answer
  • Depends on substantial increase in demand
  • Still vulnerable to certain traps such as
    over-production
  • If some use extra income to expand production
    capacity
  • If environmental practices are certified without
    focusing on balancing production with demand ?
    fall into trap of overproduction and declining
    incomes

33
A good certification programme
  • A step to bring multiple goals to commodity
    system
  • Must work with other strategies as part of system
    re-design
  • Changes range of allowed practices, but not
    guaranteed block of production growth drivers
  • Must build on all 3 goals (soc econ ecol)
  • Voluntary consumer behavior is the power behind
    it and also its limitation

34
And finally... we can rely on government
  • Shape incentives and rules
  • legislation
  • directives, rules and sponsoring and leading
    debates that establish agreements
  • New institutional structures
  • taxes, fines, and legal sanctions
  • direct payments
  • bringing different stakeholders into decision
    process

35
(New) institutional economics
  • Aware of interdependencies between economy and
    nature
  • Focused on transaction, empowerment and
    government failures and means to correct them
  • Investigates roles of insitutions (as principal
    agents of change)

36
Less pollution and more funds for education
Iowa tax on fertilizer use Funds used to educate
farmers in more efficient methods
37
Addressing the pollution trap with taxes

38
Lessons from CS (1/2)
  • Solution changing the system structure
  • Introducing new feedback loops
  • information, incentives, regulations concerning
    the state of resources, the surrounding
    environments and producing communities
  • MUST be strong enough to counterbalance the
    inherent pressure to increase efficiency, scale
    and level of production

39
Lessons from CS (2/2)
Designing interventions
  • an intervention should deal with the core growth
    drivers of a system
  • the more effectively it does so, the more likely
    it is that it will neutralise more traps
  • the boundaries of the solution should match the
    boundaries within which the commodity is produced
    and sold
  • e.g. all of the producers selling into a given
    market should participate in the agreement

40
So... what ecological economics is about?
  • Studying the interactions between economic
    systems and the ecosystems that they are part of
  • Shaping those interactions so as to make them as
    harmonious as possible
