Quasi-option values for enhanced information regarding genetically modified foods AgEcon
Donaghy, Peter; Rolfe, John; Bennett, Jeffrey W..
Issues concerning the long-term environmental and health risks associated with the production of genetically modified foods remain highly topical in Australia. It is unclear how consumers values for a precautionary approach to the release of genetically modified crops compares to the opportunity costs of forgoing economic growth associated with the use of these technologies. In this paper, an application of the contingent valuation method is reported. That technique was used to estimate quasi-option values held by consumers regarding a potential five year moratorium on the use of genetic modification in Australian agriculture. The results are compared to the estimated opportunity costs of imposing such a ban o Queensland consumers.

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...

Policy responses to invasive native species: issues of social and private benefits and costs AgEcon
Farquharson, Robert J.; Kelly, Jason A.; Welsh, Pam; Mazur, Kasia; Bennett, Jeffrey W..
Farm and catchment managers in Australia face decisions about controlling invasive native species (or scrub) which may infest agricultural land. The treatment of this land to remove the infestation and re-establish native pastures is likely to be expensive for landholders. Yet there are potential social benefits from such remediation and so a policy question arises of what to do to about facilitating such change. New South Wales state government legislation addresses this issue through regulations, and the Catchment Management Authorities are responsible for administering public funds to achieve associated natural resource improvements. However, the extent of the private costs and social benefits associated with such changes are not known, which precludes...

Willingness to pay for wetland improvement in Vietnam's Mekong River Delta AgEcon
Do, Thang Nam; Bennett, Jeffrey W..
A lack of information on economic values, especially non-market values, has contributed to wetland degradation in the Mekong River Delta. To fill this information gap, this study uses choice modelling to estimate biodiversity values of Tram Chim National Park in Vietnam. It is found that Vietnamese respondents are willing to pay for the wetland conservation. However, the willingness to pay estimates differ among sub-populations and are reduced by the use of a cheap talk script. Some issues of applying choice modelling, including questionnaire designs and survey methods are discussed in the context of a developing country.

Non Use Economic Values of Marine Protected Areas in the South-West Marine Area AgEcon
Gillespie, Robert; Bennett, Jeffrey W..
Australian governments are committed to the expansion of marine protected areas (MPAs) in Australian waters and have already established over 200 MPAs. However, this policy direction has a range of costs and benefits for the community which have largely remained unquantified. One of the main benefits of establishing MPAs are the non use values that the community for the protection of marine biodiversity. This study uses a dichotomous choice contingent valuation format with follow-up open-ended willingness to pay question to estimate these non use values for the establishment of MPAs in South-west Marine Region of Australia. It was found that on average Australian households would be WTP $104 for the establishment of MPAs that cover 10% of the South-west...

Cooperation And Competition In Tropical North Queensland's Nature-Based Tourism Industry AgEcon
Huybers, Twan; Bennett, Jeffrey W..
In this paper, the initial results of a survey of the strategic business relationships between nature based tourism operators in Tropical North Queensland are presented. While operators in the region cooperate in their collective competition with other tourism destinations, they compete with each other for the business of the tourists who visit the region. These simultaneous cooperative and competitive relationships between tourism businesses define the structure of the region’s tourism industry. The findings in this paper pertain mainly to the areas of cooperation between tourism operators in Tropical North Queensland. The two major areas of cooperation are destination promotion and activities regarding environmental protection.

Modelling heterogeneity in response behaviour towards a sequence of discrete choice questions: a probabilistic decision process model AgEcon
McNair, Ben J.; Heshner, David A.; Bennett, Jeffrey W..
There is a growing body of evidence in the non-market valuation literature suggesting that responses to a sequence of discrete choice questions tend to violate the assumptions typically made by analysts regarding independence of responses and stability of preferences. Decision processes (or heuristics) such as value learning and strategic misrepresentation have been offered as explanations for these results. While a few studies have tested these heuristics as competing hypotheses, none has investigated the possibility that each explains the response behaviour of a subgroup of the population. In this paper, we make a contribution towards addressing this research gap by presenting a probabilistic decision process model designed to estimate the proportion of...

An Integrated Assessment approach to linking biophysical modelling and economic valuation tools AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W.; Jakeman, Tony.
Natural resource management (NRM) typically involves complex decisions that affect a variety of stakeholder values. Efficient NRM, which achieves the greatest net environmental, social and financial benefits, needs to integrate the assessment of environmental impacts with the costs and benefits of investment. Integrated assessment (IA) is one approach that incorporates the several dimensions of catchment NRM, by considering multiple issues and knowledge from various disciplines and stakeholders. Despite the need for IA, there are few studies that integrate biophysical modelling tools with economic valuation. In this paper, we demonstrate how economic non-market valuation tools can be used to support an IA of catchment NRM changes. We develop a Bayesian...

Effects of alternative elicitation formats in discrete choice experiments AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
An elicitation format prevalently applied in DCE is to offer each respondent a sequence of choice tasks containing more than two choice options. However, empirical evidence indicates that repeated choice tasks influence choice behavior through institutional learning, fatigue, value learning, and strategic response. The study reported in this paper employs a split sample approach based on field surveys using a single binary elicitation format with a majority vote implementation as the baseline to expand the research on effects of sequential binary DCE formats. We provide evidence for effects caused by institutional learning and either strategic behavior or value learning after respondents answered repeated choice questions. However, we did not find any...

Estimating society's willingness to pay to maintain viable rural communities AgEcon
Bennett, Jeffrey W.; van Bueren, Martin; Whitten, Stuart M..
Declining populations in rural and regional areas have become a high political priority in Australia. Calls for measures to support rural communities have been prompted by substantial population declines in some country areas. In Europe and the USA, similar political pressures to halt population losses in rural and regional areas are also apparent; often as a component of the multifunctionality of agriculture. The question addressed in the present paper is whether or not the Australian tax‐paying public would be willing to pay to avoid losses of people from rural and regional areas that may result from environmental protection measures. As an integral component of two recent non‐market, environmental valuation exercises using Choice Modelling, the value of...

A BIO-ECONOMIC MODEL OF WETLAND PROTECTION ON PRIVATE LANDS AgEcon
Whitten, Stuart M.; Bennett, Jeffrey W..
Wetland ecosystems on privately owned farms – such as those on the Murrumbidgee River Floodplain in the state of New South Wales, Australia – provide a mix of potentially valuable outputs to their owners and the wider community. The mix of values generated is dependent on the biophysical status of the wetlands, which in-turn, is dependent on the land management in and around these multiple-output ecosystems. Despite the range of private and public values generated, management decisions are based primarily on the private values that landowners receive. These private land management decisions also affect social values. Hence, there is potentially a demand for public policy to influence decisions based on the social values wetlands generate. This paper...

Integrating economic values and catchment modelling AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Integrated catchment policies are widely used to manage natural resources in Australian catchments. Decision support tools available to aid integrated catchment management are often limited in their integration of environmental processes with socio-economic systems. Fully integrated models are required to support assessments of the environmental and economic trade-offs of catchment management changes. A Bayesian Network (BN) model is demonstrated to provide a suitable approach to integrate environmental modelling with economic valuation. The model incorporates hydrological, ecological and economic models for the George catchment in Tasmania. Information about the non-market costs and benefits of environmental changes is elicited using Choice Experiments,...

Scale and scope effects on communities’ values for environmental improvements in the Namoi catchment: A choice modelling approach AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
This report presents results of research designed to investigate variations in willingness to pay (WTP) estimates across different scales and scopes of environmental investments. The goal is to help catchment management authorities better prioritise their natural resource management actions at both catchment and farm levels. Five split samples were used to test for scale and scope effects. A choice-modelling (CM) analysis was used to elicit household WTP for improvements in environmental quality attributes in the Namoi catchment. The approach was developed so that value estimates could be more accurately transferred between different action scopes.

Revegetation of Regent Honeyeater habitat in the Capertee Valley: a Cost-Benefit Analysis AgEcon
Greyling, Tertius; Bennett, Jeffrey W..
This study considers the costs and benefit of the Regent Honeyeater Project in the Capertee Valley over the past 10 years. The benefits are estimated using choice modelling and the costs are based on project expenditure and forgone agricultural production. A comparison of the benefits and costs yields a benefit-cost ratio (BCR) of 4.45, which implies that the benefits outweigh the costs. However, variation in the underlying assumptions reveal significant sensitivity to the uncertainty associated with the maturation of native tree plantings and the successful establishment of a significant population of birds within the native vegetation. The Cost Benefit Analysis (CBA) is dominated by the benefit derived from protection of the native species (i.e. the...

ESTIMATING THE BENEFITS OF BIODIVERSITY PROTECTION AgEcon
Bennett, Jeffrey W..
What are the benefits of biodiversity protection? Why should those benefits be estimated? When should they be estimated … now or across future generations? Where should the benefits be estimated … locally, nationally or internationally? And, of course, how can they be estimated, if at all? This sequence of questions forms the basis of this paper. The specific benefits associated with the provision of biodiversity protection are firstly defined. The role of benefit estimation in the process of making decisions regarding the future use of ecosystem resources is then briefly reviewed noting the importance of biodiversity benefits in that process. The “extent of the market” for biodiversity protection is considered with respect to the beneficiaries across both...

Private Sector Initiatives in Nature Conservation AgEcon
Bennett, Jeffrey W..
The provision and management of protected natural areas has generally been regarded as the province of governments. Yet there are theoretical arguments to support the contention that the private sector can play a valuable role in nature conservation. There are also numerous examples of private sector initiatives in countries as economically, culturally and environmentally diverse as Australia, New Zealand, Germany and Vanuatu.

Willingness to pay for kerbside recycling the Brisbane Region AgEcon
Gillespie, Robert; Bennett, Jeffrey W..
Waste policy in Australia has a strong focus on kerbside recycling. This has a range of costs and benefits to the community, including non-market benefits. However, in Australia, there has been little investigation of household willingness to pay for kerbside recycling. This paper used mixed logit choice modelling to estimate the willingness to pay of households in Brisbane, Australia for kerbside waste collection services including kerbside recycling. It was found that households in Brisbane have a positive and significant willingness to pay of $131.49 per annum for fortnightly kerbside recycling and would be willing to pay an additional $18.30 to increase the frequency of this service to weekly. The utility of respondents was, however, found to decline...

Valuing New South Wales rivers for use in benefit transfer AgEcon
Morrison, Mark; Bennett, Jeffrey W..
The results from seven choice modelling applications designed to value improved river health in New South Wales are reported. These applications were designed to provide value estimates that could be used, through benefit transfer, to value improvements in the health of other rivers within the state. Because of limitations on the number of rivers that could be valued and populations sampled, a pooled model for use in benefit transfer was also estimated. The results indicate that both use and non‐use values were found to exist for all catchments. In addition, value estimates were found to differ across catchments when populations resident within catchments were sampled. However, when populations resident outside catchments were sampled for two of these...
