Merging capabilities and livelihoods: analyzing the use of biological resources to improve well-being
Provedor de dados: Ecology and Society
Autores: Lienert, Juri; University of Basel, Department of Social Sciences, Sustainability Research Group; juri.lienert@gmail.com; Burger, Paul; University of Basel, Department of Social Sciences, Sustainability Research Group; paul.burger@unibas.ch.
Especially poor people in developing countries depend on biological resources to manage their livelihoods and to generate income. Because these resources are usually public goods, their use is often subjected to what is known as the tragedy of the commons, potentially leading to resource depletion, environmental degradation, and loss of biodiversity, which consequently undermines the availability and capacity of resources to contribute to residents&amp;#8217; well-being in the long run. We suggest addressing this typical sustainability issue from a new angle. Against the backdrop of identifiable shortcomings within two popular analytic approaches, the capability approach (CA) and the sustainable livelihood approach (SLA), we argue for an improved...

Many Eyes on Nature: Diverse Perspectives in the Cape Horn Biosphere Reserve and Their Relevance for Conservation
Provedor de dados: Ecology and Society

Relationships between humans and nature take multiple forms. This is a fundamental issue in conservation but one that is often neglected, leading to poor conservation outcomes. It is thus imperative that we come to understand better the complex relationships between humans and nature. To do so, we need to examine &amp;#8220;nature&amp;#8221; and the often assumed dichotomy between humans and nature. We conducted a qualitative social research inquiry to explore the societal relationships with nature in the Cape Horn Biosphere Reserve in Chile. From the results, we developed a framework that illustrates how different &amp;#8220;natures&amp;#8221; are created in the three-way relationship among the individual, society, and the physical world. We further...

Economic Benefits Generated by Protected Areas: the Case of the Hoge Veluwe  Forest, the Netherlands
Provedor de dados: Ecology and Society
Autores: 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...

Effects of methodology and stakeholder disaggregation on ecosystem service valuation
Provedor de dados: Ecology and Society

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...

Culture, Nature, and the Valuation of Ecosystem Services in Northern Namibia
Provedor de dados: Ecology and Society
Defining culture as shared knowledge, values, and practices, we introduce an anthropological concept of culture to the ecosystem-service debate. In doing so, we shift the focus from an analysis of culture as a residual category including recreational and aesthetic experiences to an analysis of processes that underlie the valuation of nature in general. The empirical analysis draws on ethnographic fieldwork conducted along the Okavango River in northern Namibia to demonstrate which landscape units local populations value for which service(s). Results show that subjects perceive many places as providing multiple services and that most of their valuations of ecosystem services are culturally shared. We attribute this finding to common experiences and modes of...

There is an increasing emphasis on the restoration of ecosystem services as well as of biodiversity, especially where restoration projects are planned at a landscape scale. This increase in the diversity of restoration aims has a number of conceptual and practical implications for the way that restoration projects are monitored and evaluated. Landscape-scale projects require monitoring of not only ecosystem services and biodiversity but also of ecosystem processes since these can underpin both. Using the experiences gained at a landscape-scale wetland restoration project in the UK, we discuss a number of issues that need to be considered, including the choice of metrics for monitoring ecosystem services and the difficulties of assessing the interactions...

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&amp;#8211;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&amp;#8217;s...

Practical application of the Ecosystem Service Approach (ESA): lessons learned and recommendations for the future
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Beaumont, Nicola J; Mongruel, Remi; Hooper, Tara.
An Ecosystem Service Approach (ESA) is increasingly advocated for use in both environmental management and academic applications. However, despite extensive conceptual development, there are still very few examples of the effective use of the ESA for operational management. This contribution reports on the field application of the ESA at six marine and coastal case study sites. Each case study demonstrates a variation on an interdisciplinary approach to translate complex natural science data into ecosystem service terminology, and then explores the usefulness of this information in a management context. From these experiences 6 key recommendations are made to aid the future application of the ESA: (1) Invest resources in collective planning of ESA; (2)...

This paper reports the results of policy simulations of environmental and human health externalities arising from the production of electricity. The primary purpose of this paper is to illustrate the Maryland Externalities Screening and Valuation Model, developed for the State of Maryland's Department of Natural Resources. A secondary purpose is to estimate likely Maryland benefits from Title IV emissions reductions at electric power generation facilities. Sources and scope of benefits, and the potential of policy to achieve specific environmental and human health goals, are suggested by the results. We find that expected health benefits from reductions in power plant emissions dominate the estimated benefits of improved recreational visibility and...

RESUMEN La valoración económica de bienes ambientales complejos presenta una serie de aspectos problemáticos. Este trabajo se centra en dos de ellos: la linealidad de los atributos en función de valor de estos bienes y la heterogeneidad en las funciones de utilidad de los individuos. Para ello se propone una metodología basada en la Teoría de la Utilidad Multiatributo que permite contrastar la importancia dada a estos aspectos. Dicha metodología se aplica a un espacio natural protegido en la provincia de Granada. De los resultados se puede concluir que la no-linealidad de los atributos y la heterogeneidad de las funciones de utilidad individuales son aspectos relevantes en la valoración de bienes ambientales.

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...

Generating Revenues from WTP for Ecosystem Restoration: An Auction Experiment on Public Goods
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

FLOODING RISK AND HOUSING VALUES: AN ECONOMIC ASSESSMENT OF ENVIRONMENTAL HAZARD
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

THE INFLUENCE OF SPATIAL LAND USE PATTERNS ON RURAL AMENITY VALUES AND WILLINGNESS TO PAY FOR GROWTH MANAGEMENT: EVIDENCE FROM A CONTINGENT CHOICE SURVEY
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Johnston,   Robert J.; Bauer,   Dana Marie; Swallow,   Stephen K.
This paper reports on a contingent choice study in which residents of a rural Rhode Island community were asked to express their preferences for packages of growth management outcomes, where surveys presented both spatial and non-spatial attributes of growth management outcomes. Survey results provide insight on the extent to which estimated willingness to pay (WTP) for marginal changes in specific landscape features or land uses may be influenced by spatial considerations.  Results also characterize the potential impact of spatial context on public preferences and WTP for coordinated packages of growth management outcomes.

Integrated Hydro-Economic Modelling: Challenges and Experiences in an Australian Catchment
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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.

Economic Valuation of Forest Ecosystem Services: Methodology and Monetary Estimates
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

Global Compensation for Oil Pollution Damages: The Innovations of The American Oil Pollution Act
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

Economic Consequences of Pollinator Declines: A Synthesis
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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.

Designing choice experiments to Test for Anchoring and Framing Effects
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kragt,   Marit Ellen; Bennett,   Jeffrey W.
Choice experiments (CE) are increasingly used as a stated preference technique to value changes in non-market goods. Respondents to a CE survey are asked to make repeated choices between alternatives. Each alternative is described by a number of attributes – the attributes levels vary across alternatives and choice sets. A monetary attribute is typically included so that marginal values for changes in the non-market attributes presented can be estimated.   The monetary attribute has central importance. However, there has been limited research on the impacts on respondents’ choices of changing the (range in) levels of the monetary attribute presented in CE surveys. This is known as the ‘anchoring’ effect. The ‘framing’ of non-market attributes may also...

What's the Use? Welfare Estimates from Revealed Preference Models when Weak Complementarity does not Hold
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Herriges,   Joseph A.; Kling,   Catherine L.; Phaneuf,   Daniel J.
The focal point of the revealed preference (RP) valuation literature, including recreation demand and random utility maximization (RUM) models, has been on eliciting the "use" value associated with environmental amenities; i.e., that portion of value associated with direct use of a resource. Maler's (1974) concept of weak complementarity is typically invoked to justify this focus. Indeed, weak complementarity explicitly or implicitly underlies most of the RP literature. In this paper, we consider the measurement of welfare in RP models when weak complementarity does not hold. In particular, the Kuhn-Tucker (KT) framework (e.g., Phaneuf et al. 2000) does not impose weak complementarity a priori, raising the possibility of rejecting weakly complementary in...

Autores: 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...

Economic analysis of spatial preferences heterogeneity of water quality
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

RESULTS OF THE NORTH DAKOTA LAND VALUATION MODEL FOR THE 2001 AGRICULTURAL REAL ESTATE ASSESSMENT
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Aakre,   Dwight G.; Vreugdenhil,   Harvey G.
This report summarizes the results of the North Dakota Land Valuation Model. This model is used annually to estimate average land values by county, based on the value of production produced on that land. The county land values developed from this procedure form the basis for the 2001 valuation of agricultural land for assessment of real estate taxes. The average all land value from this analysis is multiplied by the total acres of agricultural land on the county abstract to determine each county's total agricultural land value. The State Board of Equalization compares this value with the total value assessed to agricultural property in each county. Each county is required by state statute to assess a total value of agricultural property within 5 percent of...

Is Choice Modelling Really Necessary? Public versus expert values for marine reserves in Western Australia
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: 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...

Stated Choice Experiments with Complex Ecosystem Changes: The Effect of Information Formats on Estimated Variances and Choice Parameters
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Hoehn,   John P.; Lupi,   Frank; Kaplowitz,   Michael D.
Stated choice experiments about ecosystem changes involve complex information. This study examines whether the format in which ecosystem information is presented to respondents affects stated choice outcomes. Our analysis develops a utility-maximizing model to describe respondent behavior. The model shows how alternative questionnaire formats alter respondents’ use of filtering heuristics and result in differences in preference estimates. Empirical results from a large-scale stated choice experiment confirm that different format presentations of the same information lead to different preference parameter estimates and error variances. A tabular format results in choice parameter estimates with statistically smaller variances than parameters estimated from...

A Ricardian analysis of the impact of climate change on African cropland
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Kurukulasuriya,   Pradeep; Mendelsohn,   Robert.
This study examines the impact of climate change on cropland in Africa, using a Ricardian cross-sectional approach. Relying on farm data from an 11-country survey of over 9500 farmers, annual net revenue is regressed on climate and other variables. The study confirms that current climate affects the net revenues of farms across Africa. Applying these results to possible future climates reveals that dryland farms are especially climate sensitive. Even as early as 2020, climate change could have strong negative impacts on currently dry and hot locations. By 2100, dryland crop net revenues could rise by 51% if future warming is mild and wet but fall by 43% if future climates are hot and dry. The crop net revenues of currently irrigated farms are likely to be...

Using Experimental Auctions for Marketing Applications: A Discussion
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lusk,   Jayson L.
The present article discusses general issues associated with experimental auctions and their relative advantages and disadvantages over other marketing research techniques.  Experimental auctions create an active market environment with feedback where subjects exchange real goods and real money, which is not generally the case with other methods.  The article also discusses four experimental design issues associated with experimental auctions: auction mechanism, market feedback and bidder affiliation, demand reduction and wealth effects, and multiple attribute valuation. Each of these experimental design issues, if not properly controlled, have the potential to create serious flaws in marketing recommendations.

This study introduces a prototype model for evaluating policies to abate agricultural nutrients in the Baltic Sea from a Finnish national point of view. The stochastic simulation model integrates nutrient dynamics of nitrogen and phosphorus in the sea basins adjoining the Finnish coast, nutrient loads from land and other sources, benefits from nutrient abatement (in the form of recreation and other ecosystem services) and the costs of agricultural abatement activities. The aim of this study is to present the overall structure of the model and to demonstrate its potential using preliminary parameters. The model is made flexible for further improvements in all of its ecological and economic components. Results of a sensitivity analysis suggest that...

On the Valuation of Companies with Growth Opportunities
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Dapena,   Jose Pablo.
Each company faces day to day investment opportunities. Just by staying in business the company is taking a decision of reinvesting capital. These opportunities have to be fairly valued to overcome misallocation of resources. A project with high growth opportunities requires high reinvestments to take full advantage of them until it reaches its mature stage. These investments can be seen as a succession of call options on future growth. When a company with such prospects is valued using the discounted cash flow technique and growth is taken implicitly in the growing cash flows and the residual value, the value thus obtained will be higher than the true one (under certain circumstances). Technology advances and the effects of globalization create enormous...

Autores: 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.

Land Preservation in British Columbia: An Empirical Analysis of the Factors Underlying Public Support and Willingness to Pay
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Androkovich,   Robert A.; Desjardins,   Ivan; Tarzwell,   Gordon; Tsogaris,   Peter.
This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province’s most productive agricultural land. ‘To ensure that local food production is maintained,’ ‘the economic importance of British Columbia’s agricultural sector,’ and ‘to protect the environment’ are the most important factors that underlie support for the reserve. Aggregate, provincewide willingness to pay to maintain the land reserve is substantial, with our most conservative estimate being Can$91.18 million per year.

The economic cost of wetland destruction
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Schmidt,   Carmel Elizabeth.
Wetlands are often refereed to as the ‘kidney of the river’, but what is the value of the water filtration they provide, and what is the cost of wetland destruction? This paper determines the economic value of wetlands for water filtration. It demonstrates that wetlands are of considerable economic value, even where the volume of water filtered is in excess of that required for domestic consumption. It argues that if legislation required those who destroy natural wetlands to replace the water filtration process the wetlands once provided, it would be necessary to construct water filtration plants at significant cost.

BIDDING ON RAILCARS FOR GRAIN: A STRATEGIC ANALYSIS
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Wilson,   William W.; Dahl,   Bruce L.
Many of the U.S. railroads have introduced highly differentiated services for grain shipments in recent years, generally in the area of forward guaranteed car service.  Taken together with other alternatives, these mechanisms have had the effect of establishing priority allocations among shippers.  In most cases, pricing and allocation of these services has been with some type of bidding mechanisms.  This paper explores the economic implications of these mechanisms on the grain shipping industry.  A model was developed to identify factors affecting the value of these services and was analyzed in the context of a typical midwestern grain shipment.  A game theory model of competitive bidding was also developed to analyze the effects of critical strategic...

Analysis of Farm Household Preferences in the Management of Invasive Species: The Case of Miconia in Hawaii
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Chan-Halbrendt,   Catherine; Yang,   Fang; Thomas,   Lynna; Pant,   Archana.
A major threat to Hawaii's ecosystem is the spread of invasive plant species. One such species is Miconia calvescens. Given that this plant was originally introduced to Hawaii by the horticulture industry and has negative effects on agricultural productivity, it is logical to find the farm households' preference for the control of Miconia. Using Conjoint Choice Experiment methodology, this study designed a survey to measure farm households' preferences for Miconia calvescens control program attributes. Results of the surveys indicate that the farm households are willing to support Miconia control programs if they prevent severe soil erosion and loss of biodiversity.

Autores: Tait,   Peter R.; Cullen,   Ross.
Intensification of agricultural practices is occurring in Canterbury. Dairy farm conversions continue with land use increasing 132% since 1995. Current concerns emanate predominantly from issues of water quantity and quality, in particular the degradation of lowland streams. These and other costs are not transmitted through markets for dairy products, these negative externalities represent allocation and equity concerns for regional policy makers. This study canvassed regional policy administrators, assembled available valuation studies and performed rudimentary calculations based on reviewed New Zealand literature to form an estimate of the external costs of dairy farming in Canterbury.  External costs are estimated at $28.7 to $45 million annually. Using...

This paper examines the effect of the payment vehicle on the valuation of an environmental good with the contingent valuation method (CVM). Results from three CV studies comparing different payment vehicles by using split samples when valuing environmental encroachment caused by roads in Sweden are presented and compared to results from other such split-sample studies of payment vehicle effects. The results are consistent and show that the payment vehicle affects the valuation, but not always the way expected when considering incentives to behave strategically.

With a relatively small population and 7% of the world's available freshwater resources, Canada is well placed for a world of water scarcity where the real value of water in its many uses becomes more and more apparent.  However, action is necessary to ensure that Canada continues to benefit from the social, economic and environmental goods and services derived from water resources. Experience and analysis suggests that policy and incentives play critical roles in the sustainable exploitation of natural resources. In particular, properly valuing water in all its forms and uses appears to be critical.   Analysis abroad has underlined the benefits of clearly delineating the roles of regulators, resource managers, infrastructure operators and service...

Autores: Boyer,   Tracy A.; Briggeman,   Brian C.; Norwood,   F. Bailey.
This study elicits preferences for multimedia in the classroom for students and faculty members in agricultural economics. Employing an Internet-based conjoint ranking survey, the results show that students prefer multimedia instructional tools over a traditional chalkboard/whiteboard lecture format while faculty members do not. Neither students nor faculty members are enthusiastic about electronic textbooks, and students will accept them only if they save $80. Finally, preferences for multimedia are shown to differ with students who self-report differing note-taking abilities, preferences for chalkboard lectures, and the need for an engaging class. Successful multimedia adoption requires appropriate use and lowering costs for students.

Characterizing Spatial Pattern in Ecosystem Service Values when Distance Decay Doesn’t Apply: Choice Experiments and Local Indicators of Spatial Association

Autores: Johnston,   Robert J.; Ramachandran,   Mahesh; Schultz,   Eric T.; Segerson,   Kathleen; Besedin,   Elena Y.
Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly abandoned by non-economics disciplines in favor of approaches that allow for spatial patchiness. This paper develops parallel methods to evaluate local patchiness and hot spots in stated preference welfare estimates, characterizing relevant patterns overlooked by traditional approaches.
