Oliver DekeInstitute for World Economics (IfW) Kiel Supply side externalities in markets for genetic resources
Motivation • 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. Markets for genetic resources
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 benefits“access and benefit sharing”-regulation contribution to biodiversity conservation
Structure of the talk >>To what extent can trade with genetic resources induce conservation? • Empirical evidence • Theoretical modelling framework • Solving for the equilibrium • Numerical simulation • Summary & Outlook
Empirical evidence • market prices and traded quantities? anecdotal evidence on trade with genetic resources variety of arrangements; yet limited data • economic studies: indirect prices > users’ WTP for a single species or for access to habitats low WTP (0-20 US$ per ha, e.g.) >> small revenues >> insufficient incentives for private conservation! different properties of genetic resources and its uses>> different results (max. of9177 US$ per ha, e.g.) >> different (at least no unambiguous) implications!
Theoretical framework (1) extent of conservation market structure Theoretical background: Simpson et al.(JPE,1996) [SSR] ecological conditions costs and revenues Monopsony: only one R&D firm Boundaries of habitats boundaries of land properties:Externalities among landowners
Theoretical framework (2) • (N) landowners; parcels of identical size land use decision: conservation conversion exogenous payoff () from conversion • firm’s WTP for access to a conserved parcel value of a collection of species (SSR) how many species? how dispersed across conserved parcels? > impact from externalities: the more parcels are conserved the more species are preserved. > even distribution: every species in each conserved parcel.
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:
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 R&D firm: conclude not more than one contract, any additional parcel would preserve only redundant species. • Condition for (n=1): exp. value of a single GR > cost of testing + share of cost of compensation
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
Solving for the equilibrium (3) weak ecological stability - variant • unpredictable ecological adjustments >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:
define the value ofgenetic informationV in relative terms of the costs of conservation for parameter values, numbers from existing studies Numerical simulation
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.
Outlookfuture research • stylized ecological modeling (homogeneity) >heterogeneity of parcels • market structure - monopsony >competitive demand: competition in research • no investment costs of conservation >land use decision when sunk investment prevail • static framework >dynamic aspects: firms’ incentives for long-term conservation in the presence of non-rivalry
