The inherent problems associated with applying dummy coding when including a fixed comparator in a discrete choice experiment are discussed, and the misinterpretations that may arise if the analyst is not aware of the problem are illustrated.
Abstract
This paper discusses the inherent problems associated with applying dummy coding when including a fixed comparator in a discrete choice experiment, and seeks to illustrate the misinterpretations that may arise if the analyst is not aware of the problem. This note provides two examples of possible misinterpretations with dummy coding and how it is solved with the use of effects coding.

Journal of Economic PsychologyIdentifying and analysing dominant preferences in discrete choice experiments: An application in health care
198 Citations2002Anthony Scott
The assumption that goods are traded-off to maximise utility underpins many choice-based empirical methods used to elicit stated preferences and is tested and examined in the context of a discrete choice experiment that examined stated preferences for different models of out of hours care provided by General Practitioners.
Health EconomicsThe veil of experience: do consumers prefer what they know best?
175 Citations2000Glenn Salkeld, Mandy Ryan +1 more
The results showed that consumers had a statistically significant preference for the existing service (status quo) when all other factors remained constant, suggesting that consumers make decisions under a 'veil of experience'.
Health EconomicsUsing stated preference and revealed preference modeling to evaluate prescribing decisions

Joint analyses highlight how stated preference data can be used to estimate parameters for attributes that are not observed in the marketplace, that do not vary in the Marketplace, or that are highly collinear with other attributes in actual markets.
Scottish Journal of Political EconomySensitivity of Willingness to Pay Estimates to the Level of Attributes in Discrete Choice Experiments
116 Citations2000Mandy Ryan, Sarah Wordsworth
The main issue addressed is the sensitivity of WTP estimates to the level of attributes, and the need for further research into the design and application of DCEs as a method for estimating WTP.
Health EconomicsAn experiment on simplifying conjoint analysis designs for measuring preferences
98 Citations2003Tara Maddala, Kathryn A. Phillips +1 more
This study examined whether simplifying the choice task in CA designs, by using a design with more overlap of attribute levels, provides advantages over standard minimal-overlap methods, and found no significant improvement in consistency, willingness to trade, perceived difficulty, fatigue, or efficiency.

A discrete choice experiment is carried out with users of a rheumatology clinic in the Grampian area of Scotland and was concerned with preferences for a specialist-nurse-led clinic, testing the axioms of rationality, continuity and symmetry.

Results suggest that inclusion of a two-dimensional structure to explain the relationship between cost and utility may avoid erroneous conclusions and give rise to significant changes in implicit WTP estimates.

This paper addresses the issue of response-ordering effects that may result from the ordering of dimensions of benefit within a question and shows no evidence of ordering effects.
