In many areas of applied economics, economists use observations of actual choices, or revealed preference (RP) data, to model behaviour. Individuals are assumed to make utility maximizing choices, and utility functions are estimated by analysing observed choices. A need for stated preference (SP) data arises when there are limited or no RP data available, because the good or service is new, not provided in a market context, or there is insufficient variability in choice attributes to obtain reliable estimates of their effects. Discrete choice experiments (DCEs) are an SP method of interest in health economics because they allow analysis of preferences for complex, multi-attribute goods like health care.
