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...

Assessing the marginal dollar value losses to an estuarine ecosystem from an aggressive alien invasive crab AgEcon
Bell, Brian A.; Menzies, Sharon; Yap, Michael; Kerr, Geoffrey N..
This paper reports on a case study to establish dollar values for loss of biodiversity in the New Zealand coastal marine environment. The study uses the European Shore Crab (Carcinas maenas) as the example alien invasive species and the Pauatahanui Inlet, Wellington, New Zealand, as the ecosystem representative of the coastal marine environment. Choice modelling is the stated preference tool used to elicit marginal dollar values for these various attributes of the inlet. Reallocation of existing government expenditure is used as the payment mechanism. Results indicate a wide range of dollar values for the marginal losses to the environment, with no clear trend on a distance-decay relationship. The probability distributions of the dollar values of the...

Capturing Preference Heterogeneity in Stated Choice Models: A Random Parameter Logit Model of the Demand for GM Food AgEcon
Rigby, Dan; Burton, Michael P..
Analyses of data from random utility models of choice data have typically used fixed parameter representations, with consumer heterogeneity introduced by including factors such as the age, gender etc of the respondent. However, there is a class of models that assume that the underlying parameters of the estimated model (and hence preferences) are different for each individual within the sample, and that choices can be explained by identifying the parameters of the distribution from which they are drawn. Such a random parameter model is applied to stated choice data from the UK, and the results compared with standard fixed parameter models. The results provide new evidence of preferences for various aspects of the UK food system, particularly in relation to...

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)

Comparing choice models of river health improvement for the Goulburn River AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W.; Lloyd, Chris; Dumsday, Robert G..
The extent of the benefits of improved river health remain uncertain. Quantifying these benefits is useful in prioritising policy investments. This study uses the Choice Modelling technique to estimate the value that households attach to attributes of improved river health. Data from a choice modelling survey supported by DSE Victoria are employed to elicit household preferences in a case study of the Goulburn River. Results from conditional and nested logit model specifications indicate that respondents hold positive values for higher levels of fish and bird populations and for increasing riverside vegetation. The standard Hausman test for Independence-from-Irrelevant-Alternatives (IIA) assumptions violations is found to give inconsistent results. The...

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.

Consumer attitudes toward GM food with hypothetical functional characteristics AgEcon
Marin, Floriana; Notaro, Sandra.
Since their introduction in the early 1990s, genetically modified organisms in agriculture tended to emphasize improved yield. Europeans, perceiving unacceptable risk and too little benefit, resoundingly disapproved of GMO use in agro-food processes. More recently, research has turned to developing products that use GMO components that better match consumer interest, including nutritionally enhanced foods, environmentally friendly crops, and other areas. The question that arises is whether Europeans perceive that the new, prospective benefits outweigh the olds risks, opening the market to such products. This paper investigates consumer preferences for a number of hypothetical genetic modifications in a widely consumed food product: yoghurt. We explore the...

Consumer demands for organic and genetically modified foods AgEcon
Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W..
Issues concerning consumer demands for genetically modified and organic food remain topical. It is unclear how consumers perceive issues associated with food production such as food safety, environmental impacts or animal welfare. It is also unclear how consumers might value potential changes in those issues in regional and metropolitan centres. This paper reports on research using the choice modelling technique to estimate and compare consumer demand for genetically modified and organic foods in Australia. The case study considers tomatoes, milk and beef commodities. The results draw comparisons between the contribution of associated factors influencing consumer purchasing decisions in a regional and metropolitan city. The results are relevant to the...

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...

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...

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.

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.

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...

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.

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.

Environmental economics and valuation: towards a practical investment framework for Catchment Management Authorities in New South Wales AgEcon
Farquharson, Robert J.; Hill, Christine M.; Bennett, Jeffrey W.; Tracey, Jacqueline.
The Catchment Management Authorities in New South Wales have programs that are collectively investing $436 million over four years to achieve catchment-wide natural resource/environmental improvements. In this paper, we consider the question of how to best allocate these resources so as to increase the well-being of the public within catchments and the state. We consider the current approaches used by CMAs and make a case for Benefit-Cost Analysis as an alternative means of assessing ex ante questions of priority setting at the catchment level and for project appraisal. A major issue for BCA is the estimation of potential benefits from project investments, particularly the estimation of values that catchment communities and those living outside the...

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.

Framing for incentive compatibility in choice modelling AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
The incentives that motivate respondents to reveal their preferences truthfully have been a long-standing area of research in the non-market valuation literature. A number of studies have been undertaken to investigate incentive compatibility in nonmarket valuation. Most of these used laboratory environments rather than field surveys (e.g. Carson and Burton, 2008, Harrison, 2007, Lusk and Schroeder, 2004, Racevskis and Lupi, 2008). Only a few studies investigating incentive compatibility have considered multi-attribute public goods with an explicit provision rule in a choice experiment (Carson and Groves, 2007, Collins and Vossler, 2009, Carson and Burton, 2008). The design of a choice modelling study that avoids strategic behaviour has proven particularly...

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...

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...
