The economic concept of the second-best involves the idea that multiple simultaneous deviations from a hypothetical first-best optimum may be optimal once the first-best itself can no longer be achieved, since one distortion may partially compensate for another. Within an evolutionary framework,...

Are individuals always better off when their preferences can be represented by expected utility?I study this question in a bargaining game where individuals bargain over a pie of fixed size, and I contrast the share received in the long-run by expected utility maximisers with the share they...

We investigate what statistical properties drive risk-taking in a large set of observational panel data on online poker games (n=4,450,585). Each observation refers to a choice between a safe 'insurance' option and a binary lottery of winning or losing the game. Our setting offers a real-world...

I show theoretically that applying the model of Köszegi and Rabin (2006) to a simple purchasing decision where consumers are ex-ante uncertain about the price realisation, gives - when changing the underlying distribution of expected prices - rise to counterintuitive predictions in contrast...

An important advance in the study of reference-dependent preferences is the discipline provided by coherent accounts of reference point formation. Kőszegi and Rabin (2006) provide such discipline by positing a reference point grounded in rational expectations. We examine the predictions of...

This project examines the role of heterogeneity in gain-loss attitudes for identi- fying models of expectations-based reference dependence (Kőszegi and Rabin, 2006, 2007) (KR). Different gain-loss attitudes lead to different signs for KR comparative statics. Failure to account for the known...

This project examines the role of heterogeneity in loss aversion for identifying models of expectations-based reference dependence (Kőszegi and Rabin, 2006, 2007) (KR). Different levels of loss aversion lead to different signs for comparative statics previously used to test the KR model. In an...

This paper shows that prospect theory, extended to account for differences across individuals in their patience and their valuation of the vaccination as a common good can explain why more than 40% of the population has intent to reject the Covid-19 vaccination, as well as the differences in...

This paper tests Birnbaum’s (2004) theory that the constant consequence paradoxes of Allais are due to violations of coalescing, the assumption that when two branches lead to the same consequence, they can be combined by adding their probabilities. Rank dependent utility and cumulative...

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...
