| Paper Abstract | spike command allows for a non-zero probability of zero willingness-to-pay in referendum-style contingent valuation experiments as suggested by Kristrom (1997). This property is particular usefull in experiments in which a large fraction of the population chose not to consume good being offered. In such circunstances the use of traditional parametric models based on probit and logit models are likelly to predict a negative willingness-to-pay. |
