We define a simple criterion for assessing the plausibility of Willingness to Pay (WTP) estimates obtained from discrete choice experiments. The criterion compares WTP for the bundle of attributes yielding the highest utility with a threshold value related to the highest level of the cost...

We briefly review and discuss traditional conjoint analysis (CA) and discrete choice experiments (DCEs), widely used stated preference elicitation methods in several disciplines. We pay particular attention to the origins and basis of CA, and show that it is generally inconsistent with economic...

Disagreement among researchers regarding types of optimal choice experiments is often best seen as resulting from differences in the set of assumptions researchers are willing to make about the underlying data generating process. Much of the current debate may have confused, rather than...
