Speaker: Date: Venue: Associate Dr David Philens, Centre for Study of Choice, Faculty of Business, University of Technology Sydney Tuesday 26th May, 2-3pm E4A Room 523 (level 5 seminar room) Title: Recent Developments in Best-Worst Scaling (BWS) Case 3 Abstract: BWS Case 3 is a type of Discrete Choice Experiment (DCE). Instead of experimental participants choosing the best (or 'most preferred') option in each choice set, participants choose the best and worst profiles from sets of three or more profiles. Case 3 has advantages over traditional 'first choice' DCE elicitation procedures as one obtains much more information about preferences in each choice set. In many cases, one obtains enough information to estimate choice models for single persons. We summarize and discuss key formal properties of Case 3, including how and why the task structure leads to several potential model forms. The model forms are 'new', or at least we are unaware of prior work comparing models for sequential choices with other choice strategies like strict ranking or strictly best choices. We compare the new models with current models for an example data set of choice of mobile phones. Brief Biography: David Pihlens is the Deputy Director (Academic) of the Centre for the Study of Choice (CenSoc) at the University of Technology, Sydney.
