      abstract = {This paper aims at comparing the performance of three  conjoint analyses (CA) in terms of estimated partworths,  predictive power and estimated WTP: choice experiment (CE);  ranking conjoint analysis (RCA) and best-worst scaling  (BWS). Comparisons are made in a non-hypothetical setting.  For comparison purposes in the last two formats only the  information on the most preferred option is considered. The  hypothetical CE is used as the benchmark. Olive oil is the  food product used in our experiment. Results reveal  preferences regularity between samples’ responses across  the formats implying not statistically differences in the  marginal participants’ WTP. Moreover, in an incentive  compatible context, RCA and BWS compared with CE provide  similar results regarding to the in-sample and  out-of-sample predictive power and also in terms of  decision consistency when just only the first rank data is  analyzed.},
