Previous research indicates that risky and uncertain marginal returnsfrom the public good significantly lower contributions. This paper presentsexperimental results illustrating that the effects of risk and uncertainty dependon the employed parameterization. Specifically, if the value of the...

In the framework of expected utility theory, risk attitudes are entirely capturedby the curvature of the utility function. In cumulative prospect theory (CPT) riskattitudes have an additional dimension: the weighting of probabilities. With thismodication, one question arises naturally: since...

The study investigates protective responses in low probability and high loss risk situations.Particularly, it (1) detects individual protection valuations to variations in probability versus tovariations in loss for payment decisions and choice decisions, (2) elicits the thresholdprobability in...

In a cascade experiment subjects are confronted with artificial predecessors prdecting in line with the BHW model (Bikhchandandi, Hirshleifer and Welch, 1992). Using the BDM mechanism we study subjects' probability assignments based on price limits for participating in the prediction game. We...

We examine the explanatory power of cascade models by implementing the BDM-mechanism in a simple cascade experiment in which subject have to decide on the prediction of a randomly choasen urn. Assigned price limits to participate in the prediction game are used as indicators of subjective...

This paper investigates (i) the robustness of hindsight bias in experimental assetmarkets, (ii) the time invariance of the different experimental risk elicitationmethods of certainty equivalents and binary lottery choices, and (iii) their correspondence.The results of our within-subjects...

We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices.Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

The concept of a non-extreme-outcome-additive capacity (neo-additive capacity ) is introduced.Neo-additive capacitiesmodel optimistic and pessimistic attitudes towards uncertaintyas observed in many experimental studies. Moreover, neo-additive capacities canbe applied easily in economic...

This paper empirically examines the behavioral precautionary saving hypothesis that uncertainty about future income triggers an increase in saving because of loss aversion. Guided by the theoretical model of Koszegi and Rabin (2009), we first extend their theoretical analysis to also consider...

Robo-advisors are novel tools in financial markets that provide investors with low-cost financial advice, usually based on individual characteristics like risk attitudes. In a portfolio choice experiment running over 10 weeks, we study how much investors benefit from robo advice. We also study...
