Two methods for calibrating discrete choice contingent valuation responses – the dichotomous choice with followup certainty question method of Champ et al. (1997) and the multiple bounded method of Welsh and Poe (1998) – are evaluated using data from a field validity comparison of...

Two methods for calibrating discrete choice contingent valuation responses—the dichotomous choice with follow-up certainty question method of and the multiple-bounded method of —are evaluated using data from a field validity comparison of hypothetical and actual participation decisions in a...

To date, much of the policy and research debate on contingent valuation mode effects has relied on experiences drawn from other research disciplines. This study provides the first contingent valuation phone-mail comparison that meets current standards for response rates, draws from a general...

This study provides the first contingent valuation phone-mail comparison that meets current standards for response rates, draws from a general population, is relevant to the valuation of general environmental goods, and allows comparisons with actual participation rates. Social desirability...
