| Tiivistelmä: | The NOAA Panel on Contingent Valuation advocated a "no answer" response option to dichotomous-choice payment questions, but did not give guidance as to how this additional response should be interpreted conceptually or analytically. In this paper the econometric modeling and response effects associated with multiple-bounded, polychotomous-choice payment question are explored. It is shown that using multiple bids with responses to each bid can increase the effectiveness of welfare estimates, but this approach is not free from bid design effects. Moreover, explicitly modeling uncertain responses can increase welfare estimates by over 100%. |
