Strategic bias in discrete choice experiments

An induced value laboratory experiment is conducted to explore the vulnerability of discrete choice experiments strategic misrepresentation preferences. We consider behaviour arise when an agent: (i) believes will be used determine a provision decision over set alternatives; and (ii) has expectations about relative likelihood those alternatives being selected delivered. In experiment, agents receive values for provisioning alternatives. treatments where information that their first best outcome unlikely win, we investigate extent which choices change, in manner consistent with them seeking deliver second decision. find 27% respondents misrepresent preferences reveal evidence bias. this sufficient change inferences preferred at aggregate level.
