We argue here that Hampel’s classical notion of qualitative robustness is not suitable for risk measurement, and we …When estimating the risk of a P&L from historical data or Monte Carlo simulation, the robustness of the estimate is … propose and analyze a refined notion of robustness that applies to tail-dependent law-invariant convex risk measures on Orlicz …

The most distinctive prediction of prospect theory is the fourfold pattern (FFP) of risk attitudes. People are said to … be (1) risk-seeking over low-probability gains, (2) risk-averse over low-probability losses, (3) risk-averse over high …-probability gains, and (4) risk-seeking over high-probability losses. Using simple gambles over real payoffs, we conduct a direct test …

This paper tests new "independence" properties to compare three models of risky decision making. According to the rank-affected multiplicative (RAM) weights model, all three properties should be satisfied; according to the transfer of attention exchange (TAX) model, two should be satisfied and one...

The Allais Paradox, or common consequence effect, has been a standard challenge to normative theories of risky choice since its proposal over 60 years ago. However, neither its causes nor the conditions necessary to create the effect are well understood. Two experiments test the effects of...

We demonstrate that in simple 2×2 games (cumulative) prospect theory preferences can be (semi-)evolutionarily stable, in particular, a population of players with prospect theory preferences is stable against more rational players, i.e. players with a smaller degree of probability weighting. We...
