Abstract

Eliciting subjective probability distributions in developing countries is often based on visual aids such as beans to represent probabilities and intervals on a sheet of paper to represent the support. The authors conducted an experiment in India that tested the sensitivity of elicited expectations to variations in three facets of the elicitation methodology: the number of beans, the design of the support (pre-determined or self-anchored), and the ordering of questions. The results show remarkable robustness to variations in elicitation design. Nevertheless, the added precision offered by using more beans and a larger number of intervals with a predetermined support improves accuracy.
