This study assesses the relative reliability of the most common incentive-compatible value elicitation techniques, and compares valuations generated by each technique to those from a hypothetical question. Specifically, we collect valuations for 18 common aid interventions from 793 potential aid recipients using 6 randomly assigned elicitation methods. In a follow up survey, respondents were given a ‘take-it-or-leave-it’ (TIOLI) offer for an intervention – we measure reliability as whether the elicitation method predicts the respondent’s choice at follow-up. Our results show that valuations are systematically overstated across methods and are generally not consistent with responses to a concrete TIOLI offer – only 40% of valuations were consistent with TIOLI choices.
