Última Efficiency benefits of choice model experimental design updating: a case study AgEcon Kerr, Geoffrey N.; Sharp, Basil M.H.. Efficient experimental designs offer the potential to reduce confidence intervals for parameters of interest in choice models, or to reduce required sample sizes. C-efficiency recognises the salience of willingness to pay estimates rather than utility function parameters. This study reports on a choice model application that incorporated updated statistical designs based on initial responses in order to maximise C-efficiency. The revised design delivered significant improvements.

C-efficiency recognizes the salience of willingness to pay estimates rather than utility function parameters.

Ano: 2009 URL: http://purl.umn.edu/97156 Benefit Transfer: Choice Experiment Results AgEcon Kerr, Geoffrey N.; Sharp, Basil M.H.. Benefit transfer entails using estimates of non-market values derived at one site as approximations to benefits at other sites. The method finds favour because it can be applied quickly and cheaply, however the validity of benefit transfer is frequently questioned. Published studies generally indicate that errors from the approach can be extremely large and could result in significant resource misallocations. Assessing the validity of benefit transfer is complicated by differences in the nature of study and policy sites, the changes being valued, valuation methods, time of study, availability of substitutes and complements, and demographic, social and cultural differences. A choice experiment was used to evaluate the transferability of benefit estimates...

Ano: 2004 URL: http://purl.umn.edu/97774 A Portfolio Approach for the New Zealand Multi-Species Fisheries Management AgEcon Yang, Ming Ming; Sharp, Basil M.H.; Sbai, Erwann. Marine species are reproducible resource. Maintaining the stock level of marine species and the sustainability of fisheries development become critical issues in current scientific research areas due to the explosion of human population and exacerbation of natural environment. The traditional method that protects the marine species is the single species approach which set maximum sustainable yield (MSY) to prevent over-harvest. However, with the development of technology and comprehension of marine science, the single species approach has been found obsolete and incapable of dealing with problems of severe depletion of fish stocks and escalation of fisheries confliction. Studies show that when regulations are species specific and species are part of a...

Ano: 2008 URL: http://purl.umn.edu/96660 Flood prone risk and amenity values: a spatial hedonic analysis AgEcon Samarasinghe, Oshadhi; Sharp, Basil M.H.. This study examines the impact of flood hazard zone location on residential property values. The study utilises data from over 2,000 private residential property sales occurred during 2006 in North Shore City, New Zealand. A spatial autoregressive hedonic model is developed to provide efficient estimates of the marginal effect of flood prone risks on property values. Our results suggest that a property located within a flood hazard zone sells for 4.3% less than an equivalent property located outside the flood hazard zone. Given the median house price, estimated discount associated with flood risks is approximately NZ$22,000.

Ano: 2008 URL: http://purl.umn.edu/6013 Understanding values associated with stormwater remediation options in marine coastal ecosystems: A case study from Auckland, New Zealand AgEcon Bastone, Chris; Stewart-Carbines, Megan; Kerr, Geoffrey N.; Sharp, Basil M.H.; Meister, Anton D.. This paper describes the design and implementation of a choice experiment to understand Aucklanders’ preferences for environmental qualities associated with the effects of urban run-off on marine coastal environments. Auckland’s coastal environments are affected by a range of ecological and human factors. While much research has been undertaken in the area of ecology, little is understood of human preferences for coastal environments and their management. An unlabelled choice experiment was developed with three environmental quality attributes specified at three broad coastal categories. The environmental qualities are ecological health, water clarity, and underfoot conditions. Willingness to pay estimates for these attributes indicates that respondents...
