Combining a standard measure of concern about low relative wealth and a standard measure of relative risk aversion leads to a novel explanation of variation in risk-taking behavior identified and documented by social psychologists and economists. We obtain two results: (1) Holding individual i's...

The paper develops an axiomatic framework for rational decision making. The von Neumann-Morgenstern axioms give rise to a richer risk attitude than that captured in the standard discounted expected utility model. I derive three models that permit a more comprehensive risk evaluation. These...

The literature reports a tendency that future losses are discounted less than future gains, the so-called sign effect in intertemporal decision making. In this article, we study implications of the sign effect on risk taking: If future losses are discounted less than future gains, mixed...

Companies are increasingly adopting Artificial Intelligence (AI) today. Recently however debates started over the risk of human cognitive biases being replicated (and scaled) by AI. Research on biases in AI predicting consumer choice is incipient and focuses on observable biases. We provide a...

We study the effect of changing income on optimal decisions in the multidimensional expected utility framework with strongly separable preferences. Using the Kihlstrom and Mirman (1974) (KM) utility representation, we show that the effect of changing income can be decomposed into a modified...

Building on Kihlstrom and Mirman (1974)'s formulation of risk aversion in the case of multidimensional utility functions, we study the effect of risk aversion on optimal behavior in a general consumer's maximization problem under uncertainty. We completely characterize the relationship between...

Evidence from hypothetical scenarios strongly suggests the existence of a sunk cost bias, the tendency to ‘throw good money after bad money.’ However, the few studies using incentives are inconclusive. In addition, evidence on potential psychological channels underlying such a bias is...

Do emotions affect the decision between change and the status quo? We exploit exogenous variation in emotions caused by rain and analyze data on more than 870,000 municipal vote outcomes in Switzerland to address this question. The empirical tests are based on administrative ballot outcomes and...
