4. Also note that the formulation in equation (3) has two major foundations that permit us to link choice behavior stated in a conjoint choice survey and the respondent's preference for the attributes. The first is the Lancastrian utility theory, which states that consumers derive utility from attributes of a good or service, rather than from the good directly. The second is the random utility theory, which postulates that individual utility is unknown but can be decomposed into a systematic or deterministic component and the stochastic error component. Thus, attributes of a good are perfectly correlated with the service perceived by the consumer. This theoretical distinction is useful when analysts want to examine which signals most effectively communicate the service that provides the desired utility (Darby et al. 2008).
