AB  - We introduce a protocol for measuring the construct validity of competing Willingness-To-Pay (WTP) distributions derived from mixed logit models. The protocol is based on a two-round survey. Round one consists in a standard Discrete Choice Experiment (DCE) sample survey at the end of which competing models are estimated. Round two introduces additional respondents who, in addition to taking part in the same DCE, are asked to identify the money value interval that better reflects their preferences using a set of values drawn from the estimated range of WTPs obtained from competing models estimated on the previous sample.
