This paper addresses the issues of how learning and fatigue effects related to the repeated choices potentially affect respondents’ stated preferences in a Choice Experiment setting. In a case study concerning food quality attributes in chicken breast filet, the results show that a learning effect is indeed present in a sequence of 16 choice sets, whereas there is no evidence of fatigue effects...

In this paper we propose theoretically consistent welfare measurement of use and nonuse values for an improvement in environmental quality with revealed and stated preference data. An analytical model based on the comparative static analysis of the variation function that describes the relationship between recreation demand and dichotomous choice contingent valuation models is estimated. Our re...

The first study, “Combining Revealed Preference Data with Stated Preference Data: A Latent Class Approach”, proposes a new framework to combine revealed and stated preference data when the convergent validity assumption is not hold. While a substantial literature assume that convergence of the two elicitation approches in an “all or nothing” proposition; i.e., the RP and SP data are either cons...

Transportation researchers have recently introduced a stated-preference (sp) method in which the attributes of the sp alternatives are based on the choice that the respondent made in a real-world setting. This practice can enhance the realism of the sp task and the efficacy of preference revelation. However, the practice creates dependence between the sp attributes and unobserved factors, contr...

Over the past two decades, hundreds of stated preference studies have been conducted in less-developed countries. This article examines what has been learned on the methodological front from stated preference research, and it summarizes the empirical evidence from stated preference studies about household preferences in lessdeveloped countries. The main conclusion is that households’ willingnes...

A growing body of literature demonstrates that many behavioral anomalies observed in stated-preference elicitation methods such as the contingent valuation method are also observed in actual choices and vice versa. This presentation furthers the argument that such parallel behaviors should be viewed as a strength of stated-preference methods. Three well-known anomalies observed in both stated p...
