The term “Stated Preference Methods” refers to a family of techniques which use individual respondents´ statements about their preferences in a set of options to estimate utility functions. The options are typically descriptions of situations or contexts constructed by the researcher. By their nature, stated preference methods require purpose-designed surveys for their collection of data. “Contingent Valuation” is often referred to as a stated preference model.
