Gender in Committees

How does a group’s gender composition influence its decisions? Economists have found women to be more generous and egalitarian than men, so one might expect groups with more women to be more generous/egalitarian. Group polarization, whereby discussions amplify preexisting attitudes (a phenomenon well-established in psychology), would enhance that effect. We report experimental evidence. Femalemajority groups are more generous/egalitarian than male-majority groups,ut female unisex groups are not the most generous/egalitarian. We discuss how these findings accord with our derived conjectures, and what can be learned regarding the influence of gender composition on committee decision-making more generally.
