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.

Confronting Uncertainty and Missing Values in Species Conservation Investment with Environmental Value Transfer AgEcon
Akter, Sonia; Grafton, R. Quentin.
Decision tools for species conservation, such as benefit cost analysis (BCA) and project prioritization protocol (PPP) use monetary values to measure benefits or to assign priorities across species. Non-use (or passive) values are an important, yet difficult to quantify, category of benefits. When not estimated they may be assigned a zero value by decision makers. This results in the under-provision of conservation dollars to substantial non-use values generating projects and actions. To overcome the problem, we provide a guide to environmental value transfer (EVT) that allows decision makers to derive indirect estimates of non-use values. Environmental value transfer, together with consideration of estimated benefits uncertainty, promise better decision...

Determinants of Participation in a Catastrophe Insurance Programme: Empirical Evidence from a Developing Country AgEcon
Akter, Sonia; Brouwer, Roy; Chowdhury, Saria; Aziz, Salina.
The paper presents empirical evidence of the determinants of catastrophe insurance participation in one of the poorest and most disaster prone countries in the world. In a large-scale household survey carried out in 2006 we ask 3,000 residents in six different districts in Bangladesh facing various environmental risk exposure levels about their willingness to participate in a catastrophe insurance programme. Combining factors put forward in risk theory and economics, we estimate a model of insurance participation. We show that the household decision to participate in the insurance programme differs depending on both exogenous and endogenous risk exposure levels. As predicted by micro-economic theory, ability to pay, measured in terms of household income...

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...

Guide to the Ex-Ante Socio-Economic Evaluation of Marine Protected Areas AgEcon
Grafton, R. Quentin; Akter, Sonia; Kompas, Tom.
Marine protected areas (MPA) potentially offer a wide range of use and non-use benefits. These include critical habitat protection, conservation of marine biodiversity, recovery of threatened and endangered marine species, and increased biomass of targeted marine species. To assess whether such benefits exceed the potential costs, we provide the first-ever comprehensive ex-ante, socio-economic guide to MPA evaluation. Our framework shows how to quantify four key values of MPAs: consumptive, non-consumptive, indirect, and non-use values. The framework also shows how to use decision tools to determine the desirability of establishing MPAs. Overall, the guide offers the promise of improved information and better decision making for marine protected areas.

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...

Testing construct validity of verbal versus numerical measures of preference uncertainty in contingent valuation AgEcon
Akter, Sonia; Bennett, Jeffrey W..
The numerical certainty scale (NCS) and polychotomous choice (PC) methods are two widely used techniques for measuring preference uncertainty in contingent valuation (CV) studies. The NCS follows a numerical scale and the PC is based on a verbal scale. This report presents results of two experiments that use these preference uncertainty measurement techniques. The first experiment was designed to compare and contrast the uncertainty scores obtained from the NCS and the PC method. The second experiment was conducted to test a preference uncertainty measurement scale that combines verbal expressions with numerical and graphical interpretations: a composite certainty scale (CCS). The construct validity of the certainty scores obtained from these three...
