摘要：In a choice experiment, when respondents are not given the opportunity to choose none of theoptions offered in a choice set, the choices can be considered forced. In this study of visitsto Hawaiian beaches, we adopt a dual-response choice experiment that allows a comparisonbetween forced and unforced choices while avoiding the possible confounding effect of choiceset complexity found in previous research. The results suggest that individual willingness to payis different in forced and unforced choice sets. Joint tests for parameter equality provide evidenceto support the use of unforced choice designs.
