Hello Sawtooth Community,
I did a traditional Conjoint value Analysis (CVA, full-profile method, cards had to be ranked) and I just estimated the part-worth utilities for the different attributes (organic label) and their levels (EU organic label, organic store label, etc.).
Now I want to test if the subjects which where interviewed in France, Netherlands, and Germany have different parth-worth utilities for the EU organic label. What is the best way of doing this? Can I perform a t-test or it is better to do a ANOVA?
Is it possible that I estimate the subjects´ willingess to pay? My problem is that I incorporated price as an additional attribute in order to provide WTP estimates. Now I just read the paper by Breidert, Hahsler and Reutterer (2006) and they say that the WTP cannot be calculated when using a traditional conjoint approach. Is there a way arround this problem, so that I can calculate the subjects WTP in the different countries?
Thanks very much for your help.
Best regards from Germany
