If a cumulative density function estimated from dichotomous choice data has an unrealistically fat right-hand tail, mean willingness to pay (WTP) will be overestimated. Truncating the range of integration results in a lower-bound estimate of the true mean WTP. A normalization procedure proposed...

In a split-sample contingent valuation study of willingness to pay (WTP) for food safety improvements, the dichotomous choice (DC) elicitation method consistently generated much larger estimates of WTP than did a continuous method. Little or none of these differences was due to bias introduced...
