Abstract: |
Does diversity of cognitive ability among market participants increase
mispricing? Does common knowledge of heterogeneity in relation to cognitive
ability of market participants further increase mispricing? We investigated
these questions by measuring subjects' cognitive ability and categorizing
those above median ability as type `H' and those below median ability as type
`L'. We then constructed three market types, each containing six traders: 6H,
6L, and 3H3L. Subjects were informed of their own cognitive type and,
depending on the treatment, that of the others in their market. We found that
heterogeneous markets (3H3L) generated significantly larger mispricing than
homogeneous markets (6H or 6L) regardless of whether subjects were informed
about the cognitive type of others in their market. Thus, diversity of
cognitive ability among market participants increased mispricing. However,
common knowledge of heterogeneity or homogeneity in the market did not have a
signi cant additional effect. |
