| 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... |

| 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... |

| 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. |

| 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. |
