    Stake effects on ambiguity attitudes for gains and losses2017In: Theory and Decision, ISSN 0040-5833, E-ISSN 1573-7187, Vol. 83, no 1, p. 19-35Article in journal (Refereed)
    Abstract [en]

    We test the effect of stake size on ambiguity attitudes. Compared to a baseline condition, we find subjects to bemore 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.

    Physician behavior and conditional altruism: the effects of payment system and uncertain health benefit2019In: Theory and Decision, ISSN 0040-5833, E-ISSN 1573-7187, Vol. 87, no 3, p. 365-387Article in journal (Refereed)
    Abstract [en]

    This paper experimentally investigates the altruistic behavior of physicians and whether this behavior is affected by payment system and uncertainty in health outcome. Subjects in the experiment take on the role of physicians and decide on the provision of medical care for different types of patients, who are identical in all respects other than the degree to which a given level of medical treatment affects their health. We investigate physician altruism from the perspective of ethical principles, by categorizing physicians according to how well their treatment decisions align with different principles for priority setting. The experiment shows that many physicians are altruistic toward their patients but also that the degree of altruism varies across patients with different medical needs. We find a strong effect of payment system that is overall unaffected by the introduction of risk and ambiguity in patients health outcomes. There is, however, substantial heterogeneity across individuals, in particular under the capitation payment system where physicians responses to the introduction of uncertainty in patient health are modulated by their own generic risk and ambiguity preferences.
