Gender-Differentiated Selection and Outside Options
Women accept lower reservation rates (WTA is 2.3 to 3.0 MWK lower for women, p < 0.01), sort 0.76 more units per day, and make 0.16 fewer errors than men. The negative selection effect is driven exclusively by men, where a 10 MWK higher minimum WTA is associated with sorting 0.20 to 0.50 fewer units per day (p < 0.05); women display no significant selection relationship.
