Sammanfattning
We seek to disentangle the effect of knowledge about an environmental
good on respondents' propensity to ignore one or more attributes on the
choice cards in a discrete choice experiment eliciting people's
preferences for increased protection of cold-water corals in Norway. We
hypothesize that a respondent's level of knowledge influences the degree
to which she ignores attributes. Respondents participated in a quiz on
cold-water coral prior to the valuation task and we use the result of
the quiz as an
ex-ante measure of their knowledge. Our results
suggests that a high level of knowledge, measured by a high quiz score,
is associated with higher probabilities of attendance to the three
non-cost attributes, although this effect is only significant for one of
them. A higher quiz score is also associated with a significantly lower
probability of attending to the cost attribute. Furthermore, although
being told your score has mixed directional effects on attribute
non-attendance, it does not significantly affect the probability of
attending to any of the attributes. Finally, allowing for attribute
non-attendance leads to substantially lower conditional
willingness-to-pay estimates. This highlights the importance of
measuring how much people know about the goods over which they are
choosing, and underlines that more research is needed to understand how
information influences the degree to which respondents ignore
attributes.
