Rectal microbicides (RMs) may offer substantial benefits in expanding HIV prevention options for key populations. From April to August 2013, we conducted Tablet-Assisted Survey Interviewing, including a discrete choice experiment, with participants r...

Addressing preference heterogeneity, multiple scales and attribute attendance with a correlated finite mixing model of tap water choice. (2015)
Journal Article

Unobserved heterogeneity of error scale in choice models is a recent extension of the better investigated issue of heterogeneity of taste intensity. It is achieved by fitting choice panel data with specifications that simultaneously handle inter-pers...

Estimating the willingness to pay for Warmer and Drier Homes (2015)
Journal Article
Gibson, J., Scarpa, R., & Rohorua, H. (2017). Estimating the willingness to pay for Warmer and Drier Homes. New Zealand Economic Papers, 51(1), 15-27. https://doi.org/10.1080/00779954.2015.1108356

New Zealand is one of several countries to use subsidies for retrofitting insulation and installing improved heating devices such as heat pumps. The valuation of these devices by the affected populations remains unknown. We investigate willingness to... Read More about Estimating the willingness to pay for Warmer and Drier Homes.

The effect of within-season variability on estimates of recreational value for trout anglers in New Zealand. (2015)
Journal Article
Mkwara, L., Marsh, D., & Scarpa, R. (2015). The effect of within-season variability on estimates of recreational value for trout anglers in New Zealand. Ecological Economics, 119, 338-345. https://doi.org/10.1016/j.ecolecon.2015.09.012

Recreational benefit estimates can be substantially improved by incorporation of data on attributes that are averaged over shorter periods of time so as to better represent within-season variability. This approach may be advantageous across a wide ra... Read More about The effect of within-season variability on estimates of recreational value for trout anglers in New Zealand..
