  • Supply side externalities in markets for genetic
    resources

2
Motivation
  • 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.

3
Motivation (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

4
Structure 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

5
Empirical 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!


6
Theoretical 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
7
Theoretical 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.

8
Theoretical 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
9
Solving 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
10
Solving 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
11
Solving 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

12
Numerical simulation
  • define the value of genetic information V in
    relative terms of the costs of conservation ?
  • for parameter values, numbers from existing
    studies

13
Summary
  • 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.

14
Outlookfuture 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
