This paper explores the criterion validity of stated preference methods through experimental referenda that capture key characteristics of a stated preference survey for a proposed environmental program. In particular, we investigate whether advisory referenda, where participant votes have either known or unknown weight in the policy decision, can elicit values comparable to that of a standard, incentive-compatible referendum. When participants regard their votes as consequential, our results suggest there is no elicitation bias with advisory referenda. For advisory referenda where participants view their votes as inconsequential, and for purely hypothetical referenda, we observe elicitation bias.
