Description

Abstract: 
Using visualization in stated preference studies has become a widespread practice while other stimuli, despite their relevance in explaining people’s valuation of nature, are rarely used. In our experiment in the field, we tested whether providing olfactory stimuli affects stated preferences compared to only showing visual stimuli. We experimentally varied the visual and olfactory states of beach quality to systematically test whether combining these stimuli could reduce the hypothetical bias in stated preference elicitation and lead to greater evaluability. To test the effect of the setting, we ran the experiment in a field setting, i.e. at the beach, and outside the field setting. Consistent with earlier studies, we observed a distinct effect of the visual stimulus. However, this effect was larger when the visual stimulus was combined with an olfactory stimulus, and it differed between users and non-users. While challenging to implement in real-world settings, our empirical results demonstrate that omitting stimuli relevant to a particular environmental setting is likely to introduce bias into the results of stated preference studies, with implications for their elicitation.
