The experiment reported in this paper identifies the effect of experience on revealed risk attitudes by examining “one-shot” insurance choices made by subjects faced with a low-probability risk and their choices when they are faced with repeated exposure to an identical risk. I find that...

We provide a model that can explain empirically relevant variations in confidence and risk taking by combining horizon-dependent risk aversion (“anxiety”) and selective memory in a Bayesian intrapersonal game. In the time series, overconfidence is more prevalent when actual risk levels are...

A risky choice experiment is based on one-dimensional choice variables and risk neutrality induced via binary lottery incentives. Each participant confronts many parameter constellations with varying optimal payoffs. We assess (sub)optimality, as well as (non)optimal satisficing, partly by...

We propose a simple, parameter‐free method that, for the first time, makes it possible to completely observe Tversky and Kahneman's (1992) prospect theory. While methods existed to measure event weighting and the utility for gains and losses separately, there was no method to measure loss...

We conduct a controlled laboratory experiment in which subjects dynamically choose to allocate their portfolio between (i) a safe asset, (ii) a risky asset and (iii) a skewed asset with negative expected value (a “bet”), in an environment where they can sometimes choose to acquire some...

Prospect Theory (PT) and Constant Relative Risk Aversion (CRRA) have clear-cut implications for the optimal asset allocation between stocks and the risk-free asset as a function of the investment horizon. While CRRA preferences imply that the allocation should be independent of the horizon, we...

We report a portfolio-choice experiment that enables us to estimate parametric models of ambiguity aversion at the level of the individual subject. The assets are Arrow securities that correspond to three states of nature, where one state is risky with known probability and two states are...

Most textbook finance literature assumes risk to be the standard deviation of returns (volatility), which is not only used by academics but also financial advisors, regulators and more. This paper comprehensively examines whether volatility is consistent with investors’ actual perception of...

Many important economic and political decisions are made by teams. In the economic literature, however, the decision units are frequently modeled as individual economic agents. The paper experimentally investigates the question to what extent observed team decisions under risk are actually...
