Good evening, I have got three questions:
1) Can we have both contingent valuation models [like eg. double bounded dichotomous choice or payment vehicle method] with a discrete choice experiment? Where the first DBDC method tries to know the wtp for only one attribute out of the 5 attributes in the next choice experiment. But with screening questions with slightly separate scenario descriptions. Will doing this influence the choice experiment ? Is it allowed?
2)If not or if other than DBDC type models, you have recommendation of some better alternative methods for doing a wtp study that can be used before choice experiment or simultaneously with it? to be used
3)Can we do such a DBDC study using NGENE and Survey engine? Or are they suited only for DCE?
Thank you so much for your reply.
