When valuing risky prospects, people typically overweight small probabilities and underweight medium and large probabilities, but there is vast heterogeneity in individual behavior. We explore the relationship between person-specific probability weights, estimated from investment decisions in a...

In this paper we analyze a large sample of individual responses to six lottery questions. Wederive a simultaneous estimate of risk aversion ? and the time preference discount rate ? perindividual. This can be done because the consumption of a large prize is smoothed over a largertime period. It...

We establish a class of fully nonlinear conditional expectations. Similarly to the usage of linear expectations when a probabilistic description of uncertainty is present, we observe analogue quantitative and qualitative properties. The type of nonlinearity captures the agents sentiments of...
