Hindsight Bias and Individual Risk Attitude within the Context of Experimental Asset Markets

Abstract

This paper investigates the robustness of hindsight bias in experimental asset markets, the time-invariance of the different experimental risk elicitation methods of certainty equivalents and binary lottery choices, and their correspondence. The results of our within-subject approach with 133 traders do not support the conjecture that hindsight bias is a general phenomenon. Furthermore, our findings challenge the presumption of time-stable risk preferences and of procedural invariance with respect to different experimental risk elicitation methods.
