Abstract: Spurred by the need to account for non-market values in various policy applications, a lively and extended debate has surrounded the presence and magnitude of hypothetical bias in stated value studies (e.g., applications of the survey-based contingent valuation method). Using the rapidly accumulating set of comparison studies, List and Gallet (2001) conducted an initial meta-analysis of the experimental protocol that may be influencing the disparity between real and hypothetical values in stated value studies. We expand the original meta-analysis by using a significantly larger (29%) data set, including variables to account for referendum formats, certainty corrections, and cheap talk scripts.
