| Water pollution is widely considered to be one of the most important environmental issues facing New Zealand. Waikato region residents have reported that water pollution is easily their most important environmental concern in each of four attitude surveys conducted by Environment Waikato. Technical and regulatory mechanisms to reduce water pollution, especially non-point source pollution from agriculture are the focus of an intensive research effort both in New Zealand and internationally. This work should assist farmers and policy makers to identify the most cost effective options for achieving any given improvement in water quality. Research described in this paper aims to complement existing research projects by developing appropriate methodology for... |

| Researchers using stated preference environmental valuation techniques are interested in identifying the extent to which framing effects impact on value estimates. Framing effects occur when the context in which the hypothetical scenarios and tradeoffs put to respondents in an application differ from those that would be important if actual transactions were involved. Because scenarios have to be defined succinctly to respondents, the challenge for researchers is to identify how the particular ‘frame’ used affects responses, and how different groups of respondents may view settings. In this paper, an application of a stated preference technique termed Choice Modelling is reported in the context of pastoral land development in Queensland and the Northern... |

| This paper describes a Choice Modelling experiment set up to investigate the relationship between distance and willingness to pay for environmental quality changes. The issue is important for the estimation and transfer of benefits. The Choice Modelling experiment allows testing distance effects on parameters of environmental attributes that imply different trade-offs between use and non-use values. The sampling procedure is designed to provide a "geographically balanced" sample. Several specifications of the distance covariate are compared and distance effects are shown to take complex shapes. Welfare analysis shows that disregarding distance produces under-estimation of individual and aggregated benefits and losses, seriously hindering the reliability of... |
