Although stated-preference surveys take various forms, the use of either text or visuals to represent attributes is uncontroversial, and they remain the commonly used formats. While prior research has investigated the impact of these commonly used formats in other disciplines, little is known about their effects on results in terms of relative importance in environmental economics literature. We conduct surveys on households’ preferences for water efficient technologies in South Africa, where we compare three presentation formats, namely text, visuals, and both text and visuals.

To the extent that diversifying income portfolio is used as a strategy for shielding against production risk, both individual risk preferences and weather uncertainty could affect crop diversification decisions. This paper is concerned with empirically assessing the effects of risk preferences and rainfall variability on farm level diversity. Unique panel data from Ethiopia consisting of experimentally generated risk preference measures combined with rainfall data are employed in the analysis.
This paper presents an application of the conditional logit model to a small, Nelson Mandela Bay neighbourhood housing data set, with the objective of determining the impact of proximity to a low-cost housing development on nearby property prices. The results of this pilot study show that the average household in the neighbourhood of Walmer is willing to pay between R27 262 and R195 564 to be located 86m further away from an existing low—cost housing development.
A large number of child deaths in developing countries could be averted if ill children received care sooner rather than later. This paper analyses the healthcare treatment pathway that is followed for children under the age of six. The majority of these children receive treatment within 24 hours. However, we find that income affects the probability of any treatment, despite freely available public healthcare, while delayed treatment for severely ill children is more likely to occur in more expensive private facilities.
