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.

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...

A cognitive psychological approach of analyzing preference uncertainty in contingent valuation AgEcon
Akter, Sonia; Bennett, Jeffrey W..
The sources of preference uncertainty in contingent valuation (CV) studies have rarely been investigated from a theoretical standpoint. This paper proposes a holistic theoretical framework of preference uncertainty that combines microeconomic theory with the theories of cognitive psychology. Empirical testing of the proposed theoretical model was carried out in Australia in the context of a national ‘Carbon Pollution Reduction Scheme (CPRS)’ to be introduced in 2010. Two separate ordered probit models for a certainty score associated with CV ‘Yes’ and ‘No’ responses were estimated. The results of the estimated regression models provide evidence supporting the hypotheses drawn from the theoretical model.

A THRESHOLD VALUE ANALYSIS OF PROPOSED FOREST RESERVES AgEcon
Bennett, Jeffrey W..
Threshold Value Analysis (TVA) may be a useful input into natural resource decision making when non-market values are involved. The decision rule under a TVA is to protect a natural resource if the (non-marketed and unquantified) benefits so arising are deemed to be greater than a threshold value defined by the (marketed and quantified) developmental benefits foregone. In this paper, threshold values are calculated for a range of forest protection options being considered under the Regional Forestry Agreements being negotiated in New South Wales. A static analysis is first undertaken. This is then enhanced by the incorporation of factors that affect the alternative streams of value through time. Extensive sensitivity testing to demonstrate the impact 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...

Analysing options for the Red Gum Forests along the Murray River AgEcon
Bennett, Jeffrey W.; Dumsday, Robert G.; Gillespie, Robert.
The Victorian Environmental Assessment Council is conducting an investigation into the management of the public land River Red Gum Forests of the Murray River Valley in Victoria. In this paper the authors apply the results of an earlier Choice Modelling exercise commissioned by VEAC to estimate the non-use values of the forests. A Benefit Cost Analysis of VEAC's draft recommendations included assessment of the market and non market values associated with different River Red Gum forest management strategies. It is concluded that the use of water for environmental flows is competitive with its use for irrigation. Other economic values associated with timber harvesting, grazing and duck hunting are small in comparison with the water values.

Australasian environmental economics: contributions, conflicts and ‘cop-outs’ AgEcon
Bennett, Jeffrey W..
Australian and New Zealand environmental economists have played a significant role in the development of concepts and their application across three fields within their subdiscipline: non-market valuation, institutional economics and bioeconomic modelling. These contributions have been spurred on by debates within and outside the discipline. Much of the controversy has centred on the validity of valuations generated through the application of stated preference methods such as contingent valuation. Suggestions to overcome some shortcomings in the work of environmental economists include the commissioning of a sequence of non-market valuation studies to fill existing gaps to improve the potential for benefit transfer.

Australian economic development and the environment: conflict or synergy? AgEcon
Bennett, Jeffrey W.; Gillespie, Robert; Dumsday, Robert G..
The populist view of economic development and the environment is that advances in one will necessarily result in a decline in the other. Evidence in the Australian context is that the dual goals can be achieved simultaneously. As economic development progresses, the increasing levels of income stimulate greater demand for environmental improvements. The population engages in more environmentally focused consumption and calls for its governments to introduce more policies designed to rehabilitate and protect environmental assets. Concurrently, the increasing levels of wealth allow for increasing expenditure on research and development into production processes that generate greater productivity and less environmental damage. The Australian agricultural...

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 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...

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.

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.

Designing choice experiments to Test for Anchoring and Framing Effects AgEcon
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...

Ecological Afforestation in China: A Market-based Approach AgEcon
Xu, Jintao; Zhang, Haipeng; Bennett, Jeffrey W.; Wang, Xuehong; Eigenraam, Mark.
This article focuses on the program of Ecological Afforestation on barren lands, degraded arable lands, harvested sites and sloped farmland in Sichuan, China. Farmers were given the opportunity to propose afforestation activities for which they would be paid an specified amount. These bids and predictions of the expected environmental benefits to be generated were used to assess the net benefit of each proposal. Most features of the bidding scheme were successfully implemented and improvements in the economic efficiency of the afforestation scheme were observed. The market-based approach is demonstrated to be a practical way forward for Ecological Afforestation in China. The bidding scheme showed savings of approximately 110,000 Yuan when compared to past...

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...
