The ratio bias—according to which individuals prefer to bet on probabilities expressed as a ratio of large numbers to normatively
equivalent or superior probabilities expressed as a ratio of small numbers—has recently gained momentum, with researchers
especially in health economics emphasizing the policy importance of the phenomenon. Although the bias has been replicated
several times, some doubts remain about its economic significance. Our two experiments show that the bias disappears once
order effects are excluded, and once salient and dominant incentives are provided. This holds true for both choice and valuation
tasks. Also, adding context to the decision problem does not alter this finding. No ratio bias could be found in between-subject
tests either, which leads us to the conclusion that the policy relevance of the phenomenon is doubtful at best. 相似文献

Ambiguity aversion appears to have subtle psychological causes. Curley, Yates, and Abrams found that the fear of negative
evaluation by others (FNE) increases ambiguity aversion. This paper introduces a design in which preferences can be private
information of individuals, so that FNE can be avoided entirely. Thus, we can completely control for FNE and other social
factors, and can determine exactly to what extent ambiguity aversion is driven by such social factors. In our experiment ambiguity
aversion, while appearing as commonly found in the presence of FNE, disappears entirely if FNE is eliminated. Implications
are discussed.

This paper investigates how letting people predict others’ choices under risk affects subsequent own choices. We find an improvement of strong rationality (risk neutrality) for losses in own choices, but no such improvement for gains. There is no improvement of weak rationality (avoiding preference reversals). Overall, risk aversion in own choices increases. Conversely, for the effects of own choices on predicting for others, the risk aversion predicted in others’ choices is reduced if preceded by own choices, for both gains and losses. Remarkably, we find a new probability matching paradox at the group level. Relative to preceding studies on the effects of predicting others’ choices, we added real incentives, pure framing effects, and simplicity of stimuli. Our stimuli were maximally targeted towards our research questions. 相似文献

Economic theory makes no predictions about social factors affecting decisions under risk. We examine situations in which a decision maker decides for herself and another person under conditions of payoff equality, and compare them to individual decisions. By estimating a structural model, we find that responsibility leaves utility curvature unaffected, but accentuates the subjective distortion of very small and very large probabilities for both gains and losses. We also find that responsibility reduces loss aversion, but that these results only obtain under some specific definitions of the latter. These results serve to generalize and reconcile some of the still largely contradictory findings in the literature. They also have implications for financial agency, which we discuss. 相似文献

Performance-contingent compensation by means of stock options may induce risk-taking in agents that is excessive from the point of view of the company or the shareholders. We test whether increasing shareholder control may be an effective checking mechanism to rein in such excessive risk-taking. We thus tell one group of experimental CEOs that they may have to justify their decision-making processes in front of their shareholders. This indeed reduces risk-taking and increases the performance of the companies they manage. Implications are discussed. 相似文献

We test the effect of stake size on ambiguity attitudes. Compared to a baseline condition, we find subjects to be more ambiguity seeking for small-probability gains and large-probability losses under high stakes. They are also more ambiguity averse for large-probability gains and small-probability losses. We trace these effects back to stake effects on decisions under risk (known probabilities) and uncertainty (unknown probabilities). For risk, we replicate previous findings. For uncertainty, we find an increase in probabilistic insensitivity under high stakes that is driven by increased uncertainty aversion for large-probability gains and for small-probability losses. 相似文献
