We test the implications of ambiguity aversion in a principal-agent problem with multiple agents. When output distributions are uncertain, models of ambiguity aversion suggest that tournaments may become more attractive than independent wage contracts, in contrast to the case where output...

We test the implications of ambiguity aversion in a principal-agent problem with multiple agents. Models of ambiguity aversion suggest that, under ambiguity, comparative compensation schemes may become more attractive than independent wage contracts. We test this by presenting agents with a...

This paper provides a comprehensive analysis regarding strategic interaction under expectation-based loss-aversion. First, we develop a coherent framework for the analysis by extending the equilibrium concepts of Koszegi and Rabin (2006, 2007) to strategic interaction and demonstrate how to...

We introduce a simple, easy to implement instrument for jointly eliciting risk and ambiguity attitudes. Using this instrument, we structurally estimate a two-parameter model of preferences. Our findings indicate that ambiguity aversion is significantly overstated when risk neutrality is assumed....

We propose a single evolutionary explanation for the origin of several behaviors that have been observed in organisms ranging from ants to human subjects, including risk-sensitive foraging, risk aversion, loss aversion, probability matching, randomization, and diversification. Given an initial...

Extending the equilibrium concepts of Kőszegi and Rabin (2006, 2007), this paper analyzes the strategic interaction of expectation-based loss-averse players. For loss-averse players with choice-acclimating expectations the utility from playing a mixed strategy is not linear but convex 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...

We study the bilateral trade problem put forward by Myerson and Satterthwaite (1983) under the assumption that agents are loss-averse, using the model developed by Kőszegi and Rabin (2006, 2007). We show that the endowment effect increases the sellers information rent, and that the attachment...

We give a full characterization of the continuation and stopping regions of optimal stopping of diffusions. We consider separately the case of a naive agent who is unaware of the possible time inconsistency in her behavior and the case of a sophisticated agent who is fully aware of such an...

Loss aversion, the principle that losses loom larger than gains, is among the most widely accepted ideas in the social sciences. The first part of this article introduces and discusses the construct of loss aversion. The second part of this article reviews evidence in support of loss aversion....
