Two discrete choice experiments on laboratory safety decisions and practices

Ranking in discrete choice experiments

A common problem in ethology is ranking of animal preferences for several discrete stimuli or options. We considered experiments where animals chose one of all possible simultaneously presented options. The animals might be observed at repeated occasions. In the ethological literature the analysis is often focused on testing the global hypotheses of no difference in preferences by non-parametri...

Discrete Choice Experiments Are Not Conjoint Analysis

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 demand theory, and is subject to several logical inconsistencies that make it unsuitable for use in a...

Validity and Reliability of Willingness-to-Pay Estimates from Two Overlapping Discrete- Choice Experiments

Discrete-choice experiments, while becoming increasingly popular, have rarely been tested for validity and reliability. This contribution purports to provide some evidence of a rather unique type. Two surveys designed to measure willingness-to-accept (WTA) for reform options in Swiss health care and health insurance are used to provide independent information with regard to two elements of refo...
