Effects of alternative elicitation formats in discrete choice experiments AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
An elicitation format prevalently applied in discrete choice experiments (DCEs) offers each respondent a sequence of choice tasks. Each choice task contains more than two choice options. Empirical evidence shows, however, that repeated choice tasks influence choice behaviour through institutional learning, fatigue, value learning and strategic response. The study reported in this paper uses a split sample approach. This approach was based on field surveys using a single binary elicitation format. To expand the research on effects of sequential binary DCE formats, a majority vote baseline was used. We present evidence for effects caused by institutional learning, and by either strategic behaviour or value learning, after respondents answered repeated...

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...

Environmental value and valuation over time AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
Time and value are related concepts that influence human behaviour. Although classical topics in human thinking throughout the ages, few environmental economic non-market valuation studies have attempted to link the two concepts. Economists have estimated non-market environmental values in monetary terms for over 30 years. This history of valuation provides an opportunity to compare value estimates and how valuation techniques have changed over time. This research aims to compare value estimates of benefits of a protected natural area. In 1978, Nadgee Nature Reserve on the far south coast of New South Wales was the focus of the first application of the contingent valuation method in Australia. This research aims to replicate that study using both the...

Estimating non-market values under scenario and policy ambiguity: the case of climate change mitigation in Australia AgEcon
Akter, Sonia; Bennett, Jeffrey W..
This report proposes an extension to existing models of non-expected utility (NEU) in the stated preference (SP) literature. The extension incorporates the impact of multiple sources of ambiguity in individual decision making behaviour. Empirical testing of the proposed decision model was carried out in Australia using a dichotomous choice contingent valuation study of a national carbon pollution reduction scheme (CPRS). The results of the study demonstrate that subjective expectations of the context scenario and subjective policy expectations are important determinants of individual decision making in a stated preference framework. The results of the study also demonstrate that decision weight functions are non-linear (quadratic) in subjective scenario...

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...

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...

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...

Household perceptions of climate change and preferences for mitigation action: the case of the Carbon Pollution Reduction Scheme in Australia AgEcon
Akter, Sonia; Bennett, Jeffrey W..
The study aims to reveal Australian households’ perceptions of climate change and their preferences for climate change mitigation actions. A web-based survey was conducted in November 2008 in which about 600 New South Wales households were asked for their willingness to bear extra household expenditure to support the ‘Carbon Pollution Reduction Scheme (CPRS)’ as proposed by the Australian government. The Contingent Valuation Method (CVM), a widely used non-market valuation technique, was applied using the single bounded dichotomous choice elicitation format. Results of the study demonstrate that, currently, there is a positive demand for climate change mitigation action in Australia. The main motivation for this positive demand stems from a desire to avoid...

Household perceptions of climate change and preferences for mitigation action: the case of the Carbon Pollution Reduction Scheme in Australia AgEcon
Akter, Sonia; Bennett, Jeffrey W..
This study aims to show how Australian households perceive climate change and what they are prepared to do to reduce the harmful effects of climate change. A web-based survey in November 2008 asked approximately 600 New South Wales households about their willingness to pay additional household expenses caused by the Carbon Pollution Reduction Scheme (CPRS) proposed by the Australian government. The Contingent Valuation Method (CVM), a widely used non-market valuation technique, was applied. Results of the study show there is a positive demand to mitigate climate change in Australia resulting from a wish to avoid climate change. Households’ willingness to pay (WTP) for climate change was, however, significantly curbed as households was uncertain about...

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...

Investigating the Effects of Attribute Level Framing and Changing Cost Levels in Choice Experiments AgEcon
Kragt, Marit Ellen; Bennett, Jeffrey W..
Choice experiments (CE) are increasingly used to estimate the values of non-market goods and services. A cost attribute is typically included in a CE questionnaire to estimate monetary values for changes in the non-market attributes presented. Although the cost attribute is centrally important, there has been limited research into the impacts of varying cost attribute levels on respondents’ choices in CE surveys. The context in which non-market attributes are presented to respondents (the ‘attribute frame’) may also affect value estimates. The challenge for CE practitioners is to identify the ‘appropriate’ attribute frames and cost level range. Results from a CE study in Tasmania show that respondents’ preferences are not impacted by describing an...

Location differences in communities’ preferences for environmental improvements in selected NSW catchments: A Choice Modelling approach AgEcon
Mazur, Kasia; Bennett, Jeffrey W..
To elicit household willingness to pay (WTP) for improvements in environmental quality in three NSW catchments (Lachlan, Namoi and Hawkesbury-Nepean), a choice modelling (CM) study was conducted. This report presents results of research designed to investigate variations in WTP across different communities. The communities included local residents, distant/urban and distant/rural residents. Nine split samples were established to test for ‘location effects’. The analysis involved both conditional logit and random-parameters logit models. Natural resource management (NRM), including Catchment Management Authorities (CMAs), can use the non-market values obtained from this study to guide their investment decisions.

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...

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...

Ordering effects and strategic response in discrete choice experiments AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
This study explores ordering effects and response strategies in repeated binary discrete choice experiments (DCE). Mechanism design theory and empirical evidence suggest that repeated choice tasks per respondent introduce strategic behavior. We find evidence that the order in which choice sets are presented to respondents may provide strategic opportunities that affect choice decisions (‘strategic response’). The findings propose that the ‘strategic response’ does not follow strong cost-minimization but other strategies such as weak cost-minimization or good deal/ bad deal heuristics. Evidence further suggests that participants, as they answer more choice questions, not only make more accurate choices (‘institutional learning’) but may also become...

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...
