| Choice modelling, a non‐market valuation technique, is used to explore framing issues in the context of environmental valuations. Choice modelling appears to have promise in simultaneously valuing a pool of substitute amenities and goods. Describing choices according to component attributes can also help to frame choices according to a number of trade‐offs. The statistical information available helps to determine where framing effects have occurred. Three choice modelling experiments were reviewed to show that framing effects may be more widespread in non‐market valuation studies than is commonly thought. |

| Estimates of the compensating surplus generated by changes in non-marketed environmental amenities can be estimated using stated preference valuation techniques. These are typically framed in terms of WTP tradeoffs, even if the situation of interest involves a property right vestment that calls for a WTA question. The differences created by the two questioning formats are explored in this paper using the results of two choice modelling applications. Both applications were framed on the potential for irrigation development and environmental losses in the Fitzroy River Basin, Central Queensland. The scenarios used in the applications differed only in that they used alternatively WTP and WTA questioning formats. The results indicate that robust models could... |

| 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. |

| Estimates of environmental values are frequently required as inputs to cost‐benefit analyses when evaluating alternative options for managing natural resources. One strategy to avoid the high cost of conducting empirical work when non‐market values are involved is to use value estimates from an existing source study and to transfer them to the target context of interest (a practice known as benefit transfer). However, the transfer of values is subject to a host of potential errors and could lead to significant overestimation or underestimation of welfare change. The present paper reports the results of a choice modelling study in which household values for the impacts of land and water degradation in Australia are estimated. A key objective of the present... |

| Choice experiments (CE – otherwise known as Choice Modelling) have become a widespread approach to environmental valuation in Australia, with many examples assessing the tradeoffs between river catchment management and socio-economic impacts. There is, however, limited information on the values of Australian estuaries. Furthermore, none of the existing valuation studies address catchment management changes in Tasmania. The CE study reported in this paper aims to elicit community preferences for the protection of the rivers and estuary of the George catchment in north-eastern Tasmania. Results from conditional and mixed logit models show that respondents are, on average, willing to pay between $2.47 and $4.46 for a km increase in native riverside vegetation... |

| A major limitation to the effectiveness of benefit-cost analyses of proposals involving natural ecosystems is the assertion of existence demand. Not only has confusion arisen regarding its exact definition but little has been done to establish its magnitude. Existence benefits are defined and an empirical study of the value a sample of Canberra residents places on the continued provision of the existence benefits of a particular ecosystem, Nadgee Nature Reserve, is outlined. It is concluded that while the measurement technique employed, the direct questioning of respondents, may be subject to a problem of response bias, it is capable of providing a reasonable estimate of these existence benefits. The average existence value per Canberra adult is at least... |
