Does Music Affect Visitors’ Choices for the Management and Conservation of Ecosystem Services?

Abstract

Psychological research has long demonstrated that preferences can be influenced by stimuli coming from the environment. Music, as an external stimulus influencing people behaviours, purchasing processes and spending, has been widely analysed in consumer behaviour and marketing literature. Here, we focus on the effect of music genres on preferences and willingness to pay for selected ecosystem services of a Nature Park when they are elicited with a Discrete Choice Experiment. This aspect is important in non-market valuation because music can represent an element of context-dependence for the assessment of individual choices, so that the assumption of preference stability does not hold, and welfare estimates may be biased. The results of a generalized mixed logit model evidenced a significant effect of music on preferences. If elicited preferences depend on the context on which the survey is implemented, wrong information to decision makers is provided when the choice context is altered by an uncontrolled external stimulus. This result is particularly important for applied researchers and policy makers. First, the use of protocols and guidelines that instruct respondents about the ambient background when answering a questionnaire is highly recommended, particularly for online surveys. Second, specific genres of music should be used in educational and ecosystem services conservation campaigns and also piped in visitor centres and virtual tours to encourage nature conservation and improve visitors’ sensitiveness for the environment.
