| 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... |

| The willingness to pay (WTP)/willingness to accept (WTA) disparity raises serious questions about preference elicitation techniques based on the Hicksian model of decision-making. In this paper we investigate the possibility of incorporating the strategies suggested by Plott and Zeiler (2005) in a Pivot Process mechanism and in a Choice Modelling experiment to eliminate the WTP/WTA disparity. The goal is to improve the reliability of the benefit estimates by comparing and contrasting these two methodologies. No methodological and analytical obstacles prevent the use the Pivot Process to calibrate the Choice Modelling estimates. By combining the two methods, a calibration procedure can be usefully developed to validate good hypothetical surveys and correct... |

| A Choice Modelling (CM) experiment is developed with the purpose of gaining some insight on how to identify the relevant population for the valuation of an environmental asset. The experiment is based on a survey of Perth residents over the values they attach to Kings Park, the largest urban park in Western Australia, 4/5 of which is native bushland. We design the experiment in order to isolate NUVs form UVs so that trade-offs between attributes of the asset imply tradeoffs between Use Values, Non-Use Values and money. One can then estimate the coefficients for each attribute and analyse the effect of distance on patterns of use. Preliminary results are obtained using data from a pre-survey trial of the questionnaire. |
