The elicitation of time preferences
We compare three methods for the elicitation of time preferences in an experimental setting: the Becker-DeGroot-Marschak (BDM) procedure (BDM), a second price auction and the multiple price list format. The first two methods have been used rarely to elicit time preferences. Although all methods used are broadly strategically equivalent, and should induce the same 'truthful' revelation, we find that the methods do differ: the money discount rates elicited with the multiple price list tend to be higher than those elicited with the other two methods. Furthermore, there are no significant differences between the rates elicited with the BDM and the auction elicitation procedure.
