Boundary effects in the Marschak-Machina triangle
Journal Title: Judgment and Decision Making - Year 2018, Vol 13, Issue 6
Abstract
This paper presents the results of a study that sheds new light on the shape of indifference curves in the Marschak-Machina triangle. The most important observation, obtained non-parametrically, concerns jumps in indifference curves at the triangle legs towards the triangle origin. These jumps, however, do not appear at the hypotenuse. The pattern observed suggests discontinuity in lottery valuation when the range of lottery outcomes changes and is best explained by decision-making models based on the psychological phenomenon of range dependence (Parducci, 1965; Cohen, 1992; Kontek & Lewandowski, 2018). Models founded on other psychological phenomena, e.g., discontinuity in decision weights (Kahneman & Tversky, 1979), cumulative probability weighting (Tversky & Kahneman, 1992), attention shifting (Birnbaum, 2008), overweighting of salient payoffs (Bordallo, Gennaioli & Shefrin, 2012), and treating stated probabilities as imperfect information (Viscusi, 1989), predict indifference curve shapes that differ from the one obtained in this study.

Magical thinking in predictions of negative events: Evidence for tempting fate but not for a protection effect
In this paper we test two hypotheses regarding magical thinking about the perceived likelihood of future events. The first is that people believe that those who “tempt fate” by failing to take necessary precautions are m...
How should we measure Americans’ perceptions of socio-economic mobility?
Several scholars have suggested that Americans’ (distorted) beliefs about the rate of upward social mobility in the United States may affect political judgment and decision-making outcomes. In this article, we consider t...
The influence of identifiability and singularity in moral decision making
There is an increased willingness to help identified individuals rather than non-identified, and the effect of identifiability is mainly present when a single individual rather than a group is presented. However, identif...
Making decision research useful - not just rewarding
An experienced decision aider reflects on how misaligned priorities produce decision research that is less useful than it could be. Scientific interest and professional standing may motivate researchers - and their funde...
