Risk aversion and framing effects
Louis Lévy-Garboua,Louis Lévy-Garboua,Hela Maafi,Hela Maafi,David Masclet,David Masclet,Antoine Terracol +6 more
TL;DR: The authors investigated framing effects by replicating the Holt and Laury's (Am. Econ. Rev. 92:1644-1655, 2002) procedure for measuring risk aversion under various frames.
Journal ArticleDOI
Estimating representations of time preferences and models of probabilistic intertemporal choice on experimental data
Pavlo R. Blavatskyy,Hela Maafi +1 more
TL;DR: Rank-dependent discounted utility and its special case, the maximization of present discounted value, was found to be the best-fitting theory for about two-thirds of all subjects.
Journal ArticleDOI
Estimating Representations of Time Preferences and Models of Probabilistic Intertemporal Choice on Experimental Data
Pavlo R. Blavatskyy,Hela Maafi +1 more
TL;DR: For a great majority of subjects, the representation of time preferences in Luce’s choice model provides the best fit, and rank-dependent discounted utility and its special case—the maximization of present discounted value—turn out to be the best-fitting theory.
Journal ArticleDOI
Consistent inconsistencies? Evidence from decision under risk
TL;DR: In this paper, the authors propose an experiment in which subjects are asked to report their preferences over risky bets so as to obtain, for each subject, three measures of inconsistencies: classical preference reversals, framing effects and preference instability.
Journal ArticleDOI
A new test of convexity–concavity of discount function
Pavlo R. Blavatskyy,Hela Maafi +1 more
TL;DR: In this article, a simple test of convexity, concavity of discount function, is proposed. But this test can be used with any utility function (which can be linear or not) and any preferences over risky lotteries (expected utility theory or not).
