Abstract

How does known diversity in cognitive ability among market participants in ufence market outcomes? We investigated this question by first measuring subjects' cognitive ability and categorizing them as 'H' type for those above median ability and 'L' type for those below median ability. We then constructed three kinds of markets with six traders each: 6H, 6L, and 3H3L. Subjects were informed of their own cognitive type and that of the others in their market. We found heterogeneous markets (3H3L) generated signi cantly larger mispricing than homogeneous markets (6H or 6L). Thus, known diversity in cognitive ability among market participants impacts mispricing.
