Belief Elicitation with a Synchronized Lottery Choice Menu
that is Invariant to Risk Attitudes
By Charles A. Holt and Angela M. Smith
This paper uses a Bayesian information processing task to compare belief elicitation mechanisms including a quadratic scoring rule, a Becker-DeGroot-Marschak pricing procedure, and a two-stage menu of lottery choices that is structured to identify a precise point of probability indifference. The choice menu yields a higher incidence of correct Bayesian responses and lower belief error averages. Unlike the quadratic scoring rule, the binary payoffs for the lottery choice mechanism are synchronized to provide theoretical incentive-compatibility regardless of risk attitudes. In addition, the choice menu structure is more transparent and intuitive than the Becker-DeGroot-Marschak procedure.
