We study theoretically and experimentally decision making under uncertainty in a social environment. We introduce an interdependent preferences model that assumes that the decision maker evaluates monetary outcomes in relation both with his individual and his social reference point. In the...

It has been widely documented in laboratory experiments that subjects act more risk-averse when they make their decisions frequently (e.g., one as opposed to several decisions at a time), a phenomenon dubbed "myopic loss aversion" by Benartzi and Thaler (1995). The present paper uses two new...

In standard models of ambiguity, the evaluation of an ambiguous asset, as of a risky asset, is considered as an independent process. In this process only information directly pertaining to the ambiguous asset is used. These models face signi ficant challenges from the finding that ambiguity...

Prospect theory (PT) is the dominant descriptive theory of decision making under risk today. For the modeling of choices, PT relies on a psychologically founded separation of risk attitudes into attitudes towards outcomes, captured in a value function; and attitudes towards probabilities,...

This study test whether social reference points impact individual risk taking. In a laboratory experiment, decision makers observe the earnings of a peer subject before making a risky choice. We exogenously manipulate the peer earnings across two treatments. We find a significant treatment...

This paper examines the distributional impact of increases to out-of-work transfers, increases to work-contingent transfers, and increases in higher rates of income tax over the whole of life. We find that, in contrast to what is implied by standard snapshot analyses, increases to...

We propose a simple, parameter‐free method that, for the first time, makes it possible to completely observe Tversky and Kahneman's (1992) prospect theory. While methods existed to measure event weighting and the utility for gains and losses separately, there was no method to measure loss...

This paper presents a new two-parameter probability weighting function for Tversky and Kahneman (1992) cumulative prospect theory as well as its special cases — Quiggin (1981) rank-dependent utility and Yaari (1987) dual model. The proposed probability weighting function can be inverse...
