- Supply side externalities in markets for genetic
resources
2Motivation
- Markets for genetic resources
- Genetic resources show different economic
properties than other natural resources - uncertain value and non-rival use of genetic
information - Instrument for biodiversity conservation (CBD)
- natural areas withheld for a supply of genetic
resources - other ecosystem services jointly provided as
public goods.
3Motivation (2)
- Issues in genetic resources
- markets ? common property resources
- property rights
- design of (intellectual) property rights for a
sustainable (in-situ) supply of genetic
information - equitable sharing of benefitsaccess and benefit
sharing-regulation - contribution to biodiversity conservation
4Structure of the talk
gtgtTo what extent can trade with genetic
resources induce conservation?
- Empirical evidence
- Theoretical modelling framework
- Solving for the equilibrium
- Numerical simulation
- Summary Outlook
5Empirical evidence
- market prices and traded quantities?
- anecdotal evidence on trade with genetic
resources - variety of arrangements yet limited data
- economic studies indirect prices gt users WTP
for a single species or for access to habitats - low WTP (0-20 US per ha, e.g.) gtgt small
revenues gtgt insufficient incentives for private
conservation! - different properties of genetic resources and
its usesgtgt different results (max. of 9177 US
per ha, e.g.) - gtgt different (at least no unambiguous)
implications!
6Theoretical framework (1)
extent of conservation
market structure
ecological conditions
costs and revenues
- Theoretical background Simpson et al.(JPE,1996)
SSR
Monopsony only one RD firm
Boundaries of habitats?? boundaries of land
properties Externalities among landowners
7Theoretical framework (2)
- (N) landowners parcels of identical size
- land use decision conservation ? conversion
- exogenous payoff (?) from conversion
- firms WTP for access to a conserved parcel
- value of a collection of species (SSR)
- how many species? how dispersed across conserved
parcels? - gt impact from externalities the more parcels
are conserved the more species are preserved. - gt even distribution every species in each
conserved parcel.
8Theoretical framework (3)
exp.payoff value of x species - cost of
compensation
max.number of contracts
participation constraint
value of x species
species within a parcel
strong ecological stability
weak ecological stability
9Solving for the equilibrium
strong ecological stability
- the collection of genetic resources is completed
before any noticeable impact results from the
conversion in adjacent places. - payoff-maximum for the RD firm conclude not
more than one contract, any additional parcel
would preserve only redundant species. - Condition for (n1)
exp. value of a single GR gt cost of testing
share of cost of compensation
10Solving for the equilibrium (2)
weak ecological stability
- immediate ecological adjustments due to
conversion in parcels adjacent to the contracted
bioprospecting area. - firm may not be able to extract all the species
that have existed in the total area at the
point of time when the contract was concluded - - unless more than one landowner is
compensated for his costs of conservation. - equilibrium condition for an interior solution
value of a marginal conserved parcel cost of
compensation
11Solving for the equilibrium (3)
weak ecological stability - variant
- unpredictable ecological adjustments gt thresholds
- if not enough parcels are conserved, no species
with promising genetic information will survive.
- conserving a marginal parcel has two effects
- more species will exist their survival will
become more likely
- modified equilibrium condition for an interior
solution
12Numerical simulation
- define the value of genetic information V in
relative terms of the costs of conservation ?
- for parameter values, numbers from existing
studies
13Summary
- market-induced extent of conservation
- impact of ecological sensitivity (in terms of
externalities among parcels that come into
question for bioprospecting) - benchmark with no externalities
- modest extent of conservation due to
non-rivalry and homogeneous parcels. - when externalities prevail
- the higher the relative value of genetic
information the more natural areas are allocated
to conservation. - when externalities and thresholds prevail
- it is optimal to conserve not all or very large
areas.
14Outlookfuture research
- stylized ecological modeling (homogeneity)
- gtheterogeneity of parcels
- market structure - monopsony
- gtcompetitive demand competition in research
- no investment costs of conservation
- gtland use decision when sunk investment prevail
- static framework
- gtdynamic aspects firms incentives for
long-term conservation in the presence of
non-rivalry
