Jutta Roosen, Stephan Marette and Sandrine Blanchemanche   ''Value Elicitation using BDM and a Discrete Choice Mechanism'' ( 2010, Vol. 30 No.2 )     We compare the Becker-DeGroot-Marschak (BDM) mechanism to a discrete choice mechanism for revealing willingness to pay (WTP) in a lab experiment. Differences in WTP disappear when considering only engaged bidders with non-zero bids. Only WTP elicited with BDM are sensitive to the variation of quantity offered to participants.     Keywords: experimental economics, substitution JEL: C9 - Design of Experiments: General I1 - Health: General   Manuscript Received : May 16 2010   Manuscript Accepted : May 26 2010   This abstract has been downloaded 1976 times                The Full PDF of this paper has been downloaded 173658 times
