Discrete choice experimental design for alternative specific choice models: an application exploring preferences for drinking water
Seminar Room 1, Newton Institute
AbstractHealth economic applications of discrete choice experiments have generally used generic forced choice experimental designs, or to a lesser extent generic designs with an appended status quo or opt out option. Each has implications for the types of indirect utility functions that can be estimated from such designs. Less attention has been paid to allowing for alternative specific choice experiments. This paper focuses on the development and use of an experimental design that allows for both labelled alternatives and alternative specific attribute effects in the context of a best worst choice study designed to investigate preferences for different types of drinking water. Results including testing for alternative specific effects and preferences for different types of drinking water options are presented, with implications explored.
