| Tiivistelmä: | This paper has four purposes. First, the authors outline the controversy surrounding the issue of negative willingness to pay (WTP) in contingent valuation (CV) studies. Second, they use Monte Carlo simulation to examine the performance of alternative distributional assumptions in estimating WTP in the presence of varying proportions of the population holding negative WTP values. Third, they extend the simulation to investigate the performance of the mixture models that have recently been proposed for handling/identifying non-positive WTP values. Fourth, they extend the simulation to investigate the performance of the nonparametric lower bound Turnbull approach. |
