Economic analysis of spatial preferences heterogeneity of water quality AgEcon
Martin-Ortega, Julia; Brouwer, Roy; Berbel, Julio.
The main objective of this study is to account for spatial preference variability in the economic valuation of water quality improvements in the river basin context. This is expected to be particularly relevant for the implementation of the European WFD, as it will involve spatially differentiated perceptions of the benefits of water quality changes. A choice experiment is developed based on maps to elicit welfare measures for water quality improvements across sub-basins in the Guadalquivir River Basin in Spain. Variation is introduced simultaneously in the spatial distribution of goods and services and their beneficiaries, for the accounting of spatial preference heterogeneity (i.e. people’s different valuation of changes in environmental good provision...

Economic Benefits Generated by Protected Areas: the Case of the Hoge Veluwe Forest, the Netherlands Ecology and Society
Hein, Lars; Department of Environmental Sciences, Wageningen University; lars.hein@wur.nl.
Eliciting the economic benefits provided by protected areas is important in order to ensure that they are properly considered in policy and decision making. There are relatively few studies that provide a comprehensive overview of the economic benefits provided by European forest ecosystems, in spite of the large share of forests in the protected area system in most countries. An economic valuation of the ecosystem services supplied by the Hoge Veluwe forest in the Netherlands is presented. The Hoge Veluwe forest is one of the largest and most well-known protected areas in the country. The services included in the study are wood production, supply of game, groundwater recharge, carbon sequestration, air filtration, recreation, and nature conservation. A...

Economic Consequences of Pollinator Declines: A Synthesis AgEcon
Bauer, Dana Marie; Sue Wing, Ian.
This paper surveys the literature on pollinator declines and related concerns regarding global food security. Methods for valuing the economic risks associated with pollinator declines are also reviewed. A computable general equilibrium (CGE) approach is introduced to assess the effects of a global catastrophic loss of pollinators. There appears to be evidence supporting a trend towards future pollinator shortages in the United States and other regions of the world. Results from the CGE model show economic risks to both direct crop sectors and indirect non-crop sectors in the economy, with some amount of regional heterogeneity.

Economic Valuation of Forest Ecosystem Services: Methodology and Monetary Estimates AgEcon
Chiabai, Aline; Travisi, Chiara M.; Ding, Helen; Markandya, Anil; Nunes, Paulo A.L.D..
By using ad hoc value transfer protocols, this paper offers a methodological contribution and provides accurate per hectare estimates of the economic value of some selected ecosystem services for all forest biomes in the world, identified following the Millennium Ecosystem Assessment taxonomy MEA. The research also estimates potential total economic losses from policy inaction in year 2050. Final results show that total losses are significant. The total figure is €78 billion, the greatest losses coming from North America and Mexico, followed by Africa, Russia and some Asiatic countries. Most of this loss is attributable to provisioning services and carbon sequestration, while only a minor part is due to loss of cultural services. In terms of biomes the...

Effects of methodology and stakeholder disaggregation on ecosystem service valuation Ecology and Society
Brooks, Emma G. E.; University of Southampton; Global Species Programme, IUCN (International Union for Conservation of Nature); emma.brooks@soton.ac.uk; Smith, Kevin G.; Global Species Programme, IUCN (International Union for Conservation of Nature); kevin.smith@iucn.org; Holland, Robert A.; University of Southampton; R.A.Holland@soton.ac.uk; Poppy, Guy M.; University of Southampton; G.M.Poppy@soton.ac.uk; Eigenbrod, Felix; University of Southampton; F.Eigenbrod@soton.ac.uk.
Contingent valuation is one of the most commonly used methodologies utilized in ecosystem service valuation, thereby including a participatory approach to many such assessments. However, inclusion of nonmonetary stakeholder priorities is still uncommon in ecosystem service valuations and disaggregation of stakeholders is all but absent from practice. We look at four site-scale wetland ecosystem service valuations from Asia that used nonmonetary participatory stated preference techniques from a range of stakeholders, and compare these prioritizations to those obtained from the largest monetary assessments available globally, the Ecosystem Service Value Database (ESVD). Stakeholder assessment suggests very different priorities to those from monetary...

Extension multi-indice del metodo beta en valoracion agraria AgEcon
Perez, Jose Garcia; Cruz, Salvador; Rosado, Yolanda.
Resumen: El objetivo de este artículo es el estudio y generalización del método de las dos funciones de distribución, utilizado en la teoría de valoración y, más concretamente, en las valoraciones agrarias. El fundamento básico de este método, propuesto por Ballestero (1973), está en la utilización de un índice representativo del activo que pretendemos valorar y en la aceptación de una serie de hipótesis sobre la distribución de la variable índice y de la variable valor del activo. Hasta este momento y en todos los trabajos publicados sobre este método, se ha mantenido la limitación de utilizar un solo índice (aunque éste sea una síntesis de varios a los que pretende representar). En este trabajo se presenta un método que generaliza el anterior y que...

FLOODING RISK AND HOUSING VALUES: AN ECONOMIC ASSESSMENT OF ENVIRONMENTAL HAZARD AgEcon
Daniel, Vanessa; Florax, Raymond J.G.M.; Rietveld, Piet.
Climate change, the ‘boom and bust’ cycles of rivers, and altered water resource management practice have caused significant changes in the spatial distribution of the risk of flooding. Hedonic pricing studies, predominantly for the US, have assessed the spatial incidence of risk and the associated implicit price of flooding risk. Using these implicit price estimates and their associated standard errors, we perform a meta-analysis and find that houses located in the 100-year floodplain have a –0.3 to –0.8% lower price. The actual occurrence of a flooding event or increased stringency in disclosure rules causes ex ante prices to differ from ex post prices, but these effects are small. The marginal willingness to pay for reduced risk exposure has increased...

Generating Revenues from WTP for Ecosystem Restoration: An Auction Experiment on Public Goods AgEcon
Smith, Elizabeth C.; Swallow, Stephen K..
Research on public good auctions is intended to initiate development on new approaches to finance public goods, beyond government and philanthropic efforts. The researchers evaluate the potential to identify economic value for a subset of ecosystem services and markets that have the potential to provide for them. Empirical analysis focuses on public valuation for three specific types of ecosystem activities (bird habitat, sea grass restoration and shellfish restoration) in coastal Virginia. Data was collected using a field experiment employing an experimental auction approach with mechanisms to reduce free riding often seen in the experimental economics literature. These incentive mechanisms are applied to individual restoration activities and willingness...

Global Compensation for Oil Pollution Damages: The Innovations of The American Oil Pollution Act AgEcon
Boyd, James.
Via technology and operations standards, U.S. regulation exerts an important influence over worldwide marine safety standards. But in addition, several other aspects of U.S. law deserve wider international consideration and adoption. First, the Oil Pollution Act's natural resource damage provisions are an innovative and effective way to deter marine pollution and provide for the restoration of injured ecological resources. Second, the relatively strict financial requirements imposed on marine transporters help ensure that polluters, rather than the public, pay if damage is caused. Liability and financial responsibility rules are not unknown in other countries. But the United States has a longer history with implementation and applies its rules more...

Habitat Scale Mapping of Fisheries Ecosystem Service Values in Estuaries Ecology and Society
O’Higgins, Timothy G.; Scottish Association for Marine Sciences; tim.ohiggins@gmail.com; Ferraro, Steven P.; U.S. Environmental Protection Agency;; Dantin, Darrin D.; U.S. Environmental Protection Agency;; Jordan, Steve J.; U.S. Environmental Protection Agency;; Chintala, Marnita M; U.S. Environmental Protection Agency;.
Little is known about the variability of ecosystem service values at spatial scales most relevant to local decision makers. Competing definitions of ecosystem services, the paucity of ecological and economic information, and the lack of standardization in methodology are major obstacles to applying the ecosystem-services approach at the estuary scale. We present a standardized method that combines habitat maps and habitat–faunal associations to estimate ecosystem service values for recreational and commercial fisheries in estuaries. Three case studies in estuaries on the U.S. west coast (Yaquina Bay, Oregon), east coast (Lagoon Pond, Massachusetts), and the Gulf of Mexico (Weeks Bay, Alabama) are presented to illustrate our method’s...

Integrated Hydro-Economic Modelling: Challenges and Experiences in an Australian Catchment AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Integrated catchment policies are widely used to manage natural resources in Australian catchments. Integration of environmental processes with socio-economic systems is often difficult due to the limitations of decision support tools. To support assessments of the environmental and economic trade-offs of changes in catchment management, fully integrated models are needed. This research demonstrates a Bayesian Network (BN) approach to integrating environmental modelling with economic valuation. The model incorporates hydrological, ecological and economic models for the George catchment in Tasmania. Choice experiments were used to elicit information about the non-market costs and benefits of environmental changes. This allows the efficiency of alternative...

Is Choice Modelling Really Necessary? Public versus expert values for marine reserves in Western Australia AgEcon
Rogers, Abbie A..
One of the motivations for choice modelling is to provide values that can be used to inform decisionmakers about the non-market costs and benefits of proposed projects or policies. However, the question must be asked as to whether decision-makers consider choice modelling to be a policy relevant tool. There may be more cost-effective and convenient means of providing comparable policy guidance than commissioning a choice modelling study. For example, advice on decision options may be sought from experts, such as scientists. However, expert advice may not accurately reflect the value judgements of the public. The aim of this study is to investigate whether public and expert preferences diverge, using the choice modelling technique. Two case studies are...

Is Embedding Entailed in Consumer Valuation of Food Safety Characteristics? AgEcon
Morkbak, Morten Raun; Christensen, Tove; Gyrd-Hansen, Dorte E.; Olsen, Soren Boye.
Consumers’ preferences for food safety characteristics are investigated with particular focus on existence of an embedding effect. Embedding exists if consumer valuation of food safety is insensitive to scope. Two choice experiments have been conducted valuing food safety in respectively minced pork and chicken breasts, exemplified by avoiding human risks of Salmonella infections and strengthening the restrictions of using antibiotics in the pork production and in terms of avoiding human risks of Salmonella and Campylobacter infections respectively. The results showed no indications of an embedding effect between the food safety characteristics, in neither of the cases.

Knowledge and the Valuation of Public Goods and Experiential Commodities: Information Provision and Acquisition AgEcon
Tisdell, Clement A..
Provides empirical evidence of significant lack of relevant knowledge of some public goods and experiential commodities. It also analyses whether information provision about the attributes or characteristics of commodities is likely to result in individuals’ finding their ‘true’ preferences for these, and identifies the type and nature of information that should be conveyed to enable commodities to be appropriately valued. It also recognizes that sometimes commodities may contain attributes that individuals are unable to evaluate. Furthermore, individuals acquire and filter information about commodities. Factors influencing these activities require analysis. A cost-benefit analysis of information acquisition suggests that individuals are less likely to...
