Abstract

In many areas of economics there is a growing interest in how expertise and
preferences drive individual and group decision making under uncertainty. Increasingly,
we wish to estimate such models to quantify which of these drive decision
making. In this paper we propose a new channel through which we can empirically
identify expertise and preference parameters by using variation in decisions
over heterogeneous priors. Relative to existing estimation approaches, our \PriorBased
Identi cation" extends the possible environments which can be estimated,
and also substantially improves the accuracy and precision of estimates in those
environments which can be estimated using existing methods.
