How does risk tolerance vary with stake size? This important question cannot be adequately answered if framing effects …, nonlinear probability weighting, and heterogeneity of preference types are neglected. We show that the increase in relative risk … to gains, no coherent change in relative risk aversion is observed for losses. These results not only challenge expected …

anonymized unpublished manuscripts are examined in an experiment where subjects are paid according to their identification …

, regardless of his preferences, initial wealth or investment problem. It is also shown that no prior-independent informativeness …

useful for out-of-sample prediction. Nor do we find practical applications of Bernoulli functions in major risk …

We study the correlation of choice under risk in Holt-Laury lotteries for gains and losses with gender, the use of … the digit ratio (2D:4D) in more than 200 subjects. In males, salivary testosterone is negatively correlated with risk … aversion for gains only. In females, salivary cortisol is positively correlated with risk aversion for gains only. No other …

We correlate choice under risk in Holt-Laury lottery tasks for gains and losses with salivary testosterone, estradiol … more than 200 subjects. Risk aversion is negatively correlated with testosterone and positively correlated with cortisol, a … stress hormone, for gains only. In males, testosterone is negatively correlated with risk aversion for gains only. In females …

We study risk taking on behalf of others, both with and without potential losses. A large-scale incentivized experiment … others are more risky. Using structural estimation, we show that this increase in risk stems from a decrease in loss aversion …
