An experimental comparison of dichotomous choice contingent valuation questions and real purchase decisions

• The results of an experiment comparing the dichotomous choice contingent valuation approach with real purchase decisions for a consumer good are reported. In addition to comparing the standard DC CV approach with real decisions, the hypothesis is tested that a more conservative interpretation of the DC approach, where only absolutely sure yes responses are counted as yes responses, correctly predicts real purchase decisions. The results show that the hypothetical yes responses overestimate the real yes responses and that the hypothetical absolutely sure yes responses underestimate the real yes responses.
