Health Values and Prospect TheoryA CommentDepartment of Health Economics, University of Ulm, Germany
Department of Health Economics, University of Ulm, Germany, thomas.klose{at}mathematik.uni-ulm.de In a recent volume of Medical Decision Making, Treadwell and Lenert stated that under prospect theory, community members compared with patients underestimate the utility of health improvements. In this comment, the authors show that this statement holds only for a subset of possible preference functions. Furthermore, the authors provide arguments that, in general, the raters current health state is not the appropriate reference level if applying prospect theory to health valuations.
