The lottery-panel task for bi-dimensional parameter-free elicitation of risk attitudes

Abstract

We propose a simple task for the elicitation of risk attitudes, initially used in Sabater-Grande and Georgantzís (2002) [SGG], capturing two dimensions of individual decision making: subjects’ average willingness to choose risky projects and their sensitivity towards variations in the return to risk. We report results from a large dataset obtained from the test and discuss regularities and the desirability of its bi-dimensionality when used to explain behaviour in other contexts.Financial support by Bancaixa (P1 1B2007‐14) and the Spanish Ministry of Science and Innovation (SEJ2008/04636/ECON).
