Developing a benefit transfer database for environmental values in Queensland AgEcon
Windle, Jill; Rolfe, John.
made in one situation to related circumstances. The benefit transfer process is typically reliant on the availability of a number of source studies which have appropriate levels of reliability and relevance to the issue of interest. However, the limited number of non-market valuation studies to draw on for source values currently limits the benefit transfer process. In this paper, an alternative approach to benefit transfer is outlined where a series of valuation studies were specifically performed to build a reference data base of values for benefit transfer purposes. The choice modelling technique was used to estimate community values for protecting soil, water and vegetation stocks in Queensland, Australia, where both state and regional populations were...

A Choice Modelling Survey of Community Attitudes to Improvements in Environmental Quality in NSW Catchments AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
The survey was designed to estimate environmental values suitable for integration into MOSAIC, a bio-economic model for catchment and farm level planning. Local residents, as well as distant rural and distant urban communities, were surveyed in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean) using choice modelling (CM). The survey aimed to find out respondents’ attitudes about, and preferences for, potential natural resource management (NRM) improvements. In total, 3,997 responses were collected from seven different locations in NSW. Fourteen split samples were established to allow for testing of incentive compatibility in CM, the impact of respondent location on values held, and scale effects. This research report describes the development...

Consumer Acceptance of GM Applications in the Pork Production Chain: A Choice Modelling Approach AgEcon
Novoselova, Tatiana A.; van der Lans, Ivo A.C.M.; Meuwissen, Miranda P.M.; Huirne, Ruud B.M..
This study evaluates consumer acceptance of different GM applications in the pork production chain. In general, results indicate that consumers prefer conventional pork over pork for which genetic modification was applied. However, the negative impact of the GM applications is compensated by improvements in quality, increased animal welfare, a lower impact on the environment, less residues and a price discount. Of these benefits, increased animal welfare has the most positive effect on consumer choices. With substantial monetary compensation and presence of various benefits the consumers will attach higher utility to the GM pork than to the conventional pork. The amount of monetary compensation is dependent on the type of GM application.

Using focus groups to design a choice modelling questionnaire for estimating natural resource management benefits in NSW AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
In this study, focus group discussions were used to design a choice modelling (CM) questionnaire to estimate community wide values for the environmental and social benefits provided by natural resource management changes in the Namoi, Lachlan and Hawkesbury-Nepean catchments. This report describes the logistics of the focus groups and outlines the main conclusions drawn from the discussions. The research team conducted eight focus groups in the main urban areas of the regions where the CM survey will be conducted (Tamworth, Cowra, Goulburn and Sydney). How the CM questionnaire was developed with focus group participant input is also discussed in the report. The focus group meetings resulted in a draft questionnaire to be refined in consultation with...

Consumer's WTP for Environment-Friendly Production Methods and Collective Reputation for Place of Origin: The Case of Val di Gresta's Carrots AgEcon
Scarpa, Riccardo; Thiene, Mara; Marangon, Francesco.
This paper investigates preferences for various environment-friendly production system for carrots using discretechoice multi-attribute stated-preference data amongst buyers and explore the effect of collective reputations from growers of an Alpine valley known to be completely dedicated to organic production. Results show that buyers distinctly recognize only organic production as a production system different from the conventional one, and there is some evidence of recognition of collective reputation. As well as for marginal utility of income, substantial unobserved heterogeneity is found for many skin imperfections, origin from the organic Alpine valley and the organic production methods. The implied sample distributions of WTP for each of these random...

Protecting the Booroolong Frog in the Namoi Catchment: A Cost-Benefit Analysis AgEcon
Greyling, Tertius; Bennett, Jeffrey W..
The Booroolong frog project in the Namoi Catchment represents an environmental investment to protect the species and around 10.7 kilometres of its habitat in the catchment. The project’s benefit-cost ratio (BCR) of 8.6 indicates that the benefits outweigh the costs by a significant margin. The measures introduced by landholders, at relatively low cost, should therefore result in a significant return on investment upon project completion in 10 years time. The benefits are estimated using a choice modelling study which was recently developed for the valuation of investment in natural resource management in the Namoi Catchment. As this is a largely ex ante cost-benefit analysis, the BCR is subject to uncertainty associated with assumptions which had to be...

Decision-Making in a Social Welfare Context AgEcon
Scarborough, Helen; Burton, Michael P.; Bennett, Jeffrey W..
This paper presents analysis of the decision-making strategies adopted by respondents when confronted with potential policy options that include changes in both aggregate levels of welfare and equity in distribution. The analysis is based on the results of a choice experiment designed to estimate intergenerational distributional preferences. Non-linear welfare functions are employed within a conventional conditional logit framework. The heuristics employed by respondents in the stated preference context provide valuable insights into the application of welfare principles by respondents in determining trade-offs between the potential changes in the well-being of different generations.

Choice modelling in the development of natural resource management strategies in NSW AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
Protecting environmental services generates social benefits. At the same time, private landholders supplying these benefits may face some costs. To provide these services efficiently, policy makers need information about community values for the environment as well as landholders’ costs. This study explores how choice modelling (a non-market valuation technique) is used to estimate comment values. These include use and non-use values for increasing environmental quality in NSW catchments. Non-market valuation techniques for estimating environmental values are reviewed. This is followed by a discussion of methodological aspects of the choice modelling technique and its potential as a regional planning tool for Catchment Management Authorities (CMA’s)

Die Analyse von Lebensmittelpräferenzen mit Hilfe von Discrete-Choice-Modellen am Beispiel ökologisch produzierter Wurstwaren AgEcon
Enneking, Ulrich.
Preferences for food products are usually analysed employing multi-attributive Attitude Measurement, Conjoint Analysis and recently Discrete Choice Modelling approaches. From a theoretical point of view, Choice Modelling based on random utility theory (RUT) outperforms traditional Conjoint Analysis because of its microeconomic foundation. In this article, consumers' choice behaviour on ecologically produced sausages is analysed. A market experiment reveals brand specific reactions towards the 'Bio-Siegel', a German quality label for organic food introduced in 2002. It can also be shown that regular customers of organic food are much less price sensitive than occasional buyers.

Location differences in communities’ preferences for environmental improvements in selected NSW catchments: A Choice Modelling approach AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
A choice modelling (CM) study was conducted to elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean). This paper presents results of research designed to investigate variations in WTP across different communities including local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effect’. The analysis involved both conditional logit and random parameters logit models.

Neoclassical consumer theory and genetically modified food AgEcon
Kaye-Blake, William.
Three axioms underpin consumer choice in neoclassical theory: weak order, independence, and continuity. Two of these axioms may not hold, however, for consumers’ choices regarding genetically modified (GM) food. Consumers may evaluate product attributes differently depending on whether the food is GM or not, violating attribute independence. Some consumers may not want GM food at all, violating continuity. The axioms were empirically investigated with a choice experiment survey. The paper discusses evidence of violations of both independence and continuity, as well as a non-neoclassical approach to modelling consumer choice.

The Policy Relevance of Choice Modelling: An Application to the Ningaloo and Proposed Capes Marine Parks AgEcon
McCartney, Abbie.
One issue surrounding the use of Choice Modelling (CM) in policy is whether public and expert preferences diverge regarding particular environmental attributes. To investigate this issue two case studies use CM to value ecological attributes for the Ningaloo and proposed Capes marine parks in Western Australia. Public and expert populations are sampled, with consideration of information effects. Attention is also given to whether policy relevance can be improved by considering not only desired outcomes of the hypothetical policy options in the CM exercise, but also the management process used to achieve these outcomes. Preliminary results of the public sample identify significant impacts of both information and management process effects.

Public values for improved water security for domestic and environmental use AgEcon
Windle, Jill; Rolfe, John; Brouwer, Roy.
Metrics for evaluating environmental trade-offs can be developed with varying levels of consistency across case study sites. A key issue is whether standard evaluation experiments can be conducted over multiple sites, or whether experiments have to be tailored to each case study application. To test how useful a consistent approach is, choice modelling (CM) has been used in a number of countries. Choice modelling assess the trade-offs households are prepared to make between water use restrictions, maintaining environmental conditions in waterways, and increased water costs. This research paper reports the results of the Queensland survey. The results show that it is not possible to downplay case study framing issues and that it is not appropriate to...

Cost-Benefit Analysis of the protection of Malleefowl in the Lachlan Catchment AgEcon
Greyling, Tertius; Bennett, Jeffrey W..
A cost-benefit analysis (CBA) of an investment in the protection of malleefowl and associated native vegetation in the Lachlan Catchment’s central-west yielded a benefit-cost ratio of 1.4. The CBA is based on project expenditures over the past four years coupled with benefit estimates from a recent Choice Modelling study in the Lachlan Catchment. The project targets the protection of malleefowl on private land which has not yet been surveyed but where the species is known to be present. The CBA is subject to significant uncertainty due to a lack of available data. Nonetheless, sensitivity analysis indicates that the BCR is consistently larger than unity, if marginal in some cases. This suggests that the project is a worthwhile investment at this early...

Designing choice experiments to incorporate tests for geographic scale and scope differences AgEcon
Rolfe, John; Windle, Jill; Bennett, Jeffrey W..
Designing a choice modelling (CM) experiment to place a value on increasing protection of the Great Barrier Reef (GBR) raises complex issues. The size and diversity of the GBR, and the number of different pressures impacting on it, mean protection and improvement scenarios can be drafted in several different ways. This report discusses some of the considerations in selecting, describing and combining choice attributes. It also looks at how to incorporate tests for geographic scale (size) and scope (complexity) differences into the design of the CM survey instrument. The potential to include information about management options designed to achieve increased protection, and the associated risk and uncertainty, is also discussed.

Investigating distance effects on environmental values: a choice modelling approach AgEcon
Concu, Giovanni B..
Analysis of the relationship between distance and willingness to pay (WTP) is important for estimation and transfer of environmental benefits. Several contingent valuation (CV) studies have investigated this topic, but results are mixed. This paper describes a choice modelling (CM) application that estimates distance effects on parameters of three environmental attributes. Combinations of these attributes create different management policies for native vegetation. The CM study is based on a sampling procedure that provides a geographically balanced sample and statistical tests to choose the best specification of the distance–WTP relationship. Welfare analysis shows that disregarding distance causes under-estimation of individual and aggregated benefits and...

Diversification choices in agriculture: a Choice Modelling case study of sugarcane growers AgEcon
Windle, Jill; Rolfe, John.
Growers in the sugarcane industry have been struggling under financial pressure for several years. One option to improve farm viability might be to diversify farm enterprise income. Choice Modelling, an economic valuation technique, was used to explore the trade-offs growers make between different attributes of diversification, and how their choices may be related to certain socio-economic characteristics. Application of the technique involved surveys of cane growers in three regions of Central Queensland. This is a novel approach to assessing grower intentions that has the potential to reveal detailed information about influences on grower choices.

Exploring Scope and Scale Issues in Choice Modelling Design AgEcon
Rolfe, John; Wang, Xuehong.
The key tasks in the design of a choice modelling (CM) experiment are to define the scope, scale and frame of the tradeoffs presented to respondents. This study explores the scale and scope of choice tasks and then develops definitions of these terms. The scope of a good in a stated preference experiment refers to the dimensions used to define the good as well as the tradeoffs involved. The scale refers to the quantities involved. The framing refers to the context in which the choices are made. The discussion helps identify issues when setting the contingent market for a choice experiment.

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...
