Elicitation effects in contingent valuation: Comparisons to a multiple bounded discrete choice approach

This paper develops a multiple bounded discrete choice elicitation technique that allows respondents to express their level of voting certainty for a wide range of referendum thresholds. The paper concludes with the results of an empirical study comparing values obtained from a multiple bounded model with values derived from three standard contingent valuation elicitation formats: dichotomous choice, payment card, and open-ended. The multiple bounded discrete choice format covers the range of values associated with the other three predominantly used elicitation methods. Moreover, alternative parameterizations of the multiple bounded discrete choice model correspond to these standard elicitation techniques. (C) 1998 Academic Press.
